The probability of both gumballs not being red is 11/21.
What is the probability?
The probability of the first gumball not being red is:
P(first gumball not red) = P(blue) + P(yellow)
= (6/15) + (5/15)
= 11/15
After removing the first gumball, there are 14 gumballs left in the bag. The probability of the second gumball not being red depends on what color the first gumball was.
Case 1: The first gumball was blue
If the first gumball was blue, there are 5 blue, 4 red, and 5 yellow gumballs left in the bag. The probability of the second gumball not being red is:
P(second gumball not red | first gumball was blue) = P(blue or yellow)
= P(blue) + P(yellow)
= (5/14) + (5/14)
= 5/7
Case 2: The first gumball was yellow
If the first gumball was yellow, there are 6 blue, 4 red, and 4 yellow gumballs left in the bag. The probability of the second gumball not being red is:
P(second gumball not red | first gumball was yellow) = P(blue or yellow)
= P(blue) + P(yellow)
= (6/14) + (4/14)
= 5/7
The probability of both gumballs not being red is the product of the probabilities of each event:
P(both gumballs not red) = P(first gumball not red) * P(second gumball not red | first gumball not red)
P(both gumballs not red) = (11/15) * (5/7)
P(both gumballs not red) = 55/105
P(both gumballs not red) = 11/21
Therefore, the probability of both gumballs not being red is 11/21.

What is surface area?A solid object's surface area is a measurement of the total area that the surface of the object takes up.
The definition of arc length for one-dimensional curves and the definition of surface area for polyhedra (i.e., objects with flat polygonal faces), where the surface area is the sum of the areas of its faces, are both much simpler mathematical concepts than the definition of surface area when there are curved surfaces.
A smooth surface's surface area is determined using its representation as a parametric surface, such as a sphere.
This definition of surface area uses partial derivatives and double integration and is based on techniques used in infinitesimal calculus.
Henri Lebesgue and Hermann Minkowski at the turn of the century sought a general definition of surface area.
L × b = 300
b = 300 / L
b = 300 / 60 = 5
Hence, b equal for the top of the bookcase to have the correct area= 5 cm2.

Answer:
There is 5% of the juice left.
Step-by-step explanation:
We know that originally, the container had 80 oz of orange juice, this is 100% in our case.
Then we can write a relation:
80 oz = 100%
Now there are 4 ounces left, in the same way as before, we can write this as:
4 oz = X%
We want to find X%
First, let's write our equations:
4 oz = X%
80 oz = 100%
We can take the quotient between these two equations to get:
(4oz/80oz) = (X%/100%)
We need to solve this for X%, then we get:
(4oz/80oz)*100% = X% = 5%
This means that 4 oz is 5% of the initial volume of the juice container.
Then we can conclude that there is 5% of the juice left.
The average overseas trip cost 2708 per visitor. If we assume a normal distribution with a standard deviation of 405 what is the probability that the cost for a randomly selected trip is more than 3000? If we elect a random sample of 30 overseas trips and find the mean of the sample, what is the probability that the mean is greater than 3000
Randomly selected trip: 24.5% chance > $3000. Sample mean of 30 trips: very small chance > $3000.
Utilizing z-score recipe:
z = (x - μ)/σ
where x is the worth we're keen on, μ is the mean, and σ is the standard deviation.For the primary inquiry:
z = (3000 - 2708)/405 = 0.69
Utilizing a standard typical circulation table or number cruncher, we can track down that the likelihood of getting a z-score more prominent than 0.69 is around 0.245. Consequently, the likelihood that the expense for a haphazardly chosen trip is more than 3000 is around 0.245 or 24.5%.
For the subsequent inquiry:
The example size (n) = 30, and the standard deviation (σ) = 405/sqrt(30) = 74.02 (approx.)
z = (3000 - 2708)/74.02 = 3.94
Utilizing a standard typical dissemination table or number cruncher, we can track down that the likelihood of getting a z-score more prominent than 3.94 is tiny, near 0. Consequently, the likelihood that the mean expense of an example of 30 abroad excursions is more noteworthy than 3000 is tiny.

The probability that the mean is greater than 3000 is 24.5%
What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur.
Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.
Given that, the average overseas trip cost 2708 per visitor, assuming a normal distribution with a standard deviation of 405 what is the probability that the cost for a randomly selected trip is more than 3000
z-score:
z = (x - μ)/σ
where μ is the mean, and σ is the standard deviation.
So,
z = (3000 - 2708)/405 = 0.69
Z-score 0.69 = 0.245.
Thus, the likelihood that the expense of the chosen trip is more than 3000 is around 0.245 or 24.5%.
The sample size (n) = 30, and the standard deviation (σ) = 405/√(30) = 74.02 (approx.)
z = (3000 - 2708)/74.02 = 3.94
z-score 3.94 = 0.
Thus, the likelihood that the mean expense of an example of 30 abroad excursions is more noteworthy than 3000 is tiny.

Review the graph of a piecewise function.
The range of the function is the set of all real numbers greater than or equal to -2, because the lowest possible value of the function is -2, which occurs at x = 2.
What is a piecewise function ?
A piecewise function is a function that is defined by different equations on different parts of its domain. The graph of a piecewise function consists of several distinct parts, each corresponding to a different equation.
The graph shown is an example of a piecewise function. The function is defined using different equations on different intervals of the domain.
On the interval from negative infinity to negative 2, the function is defined by the equation y = 2. This means that the value of the function is always 2 on this interval, regardless of the value of x.
On the interval from negative 2 to 2, the function is defined by the equation y = -x. This means that the value of the function is equal to the negative of x on this interval.
On the interval from 2 to positive infinity, the function is defined by the equation y = 2. This means that the value of the function is always 2 on this interval, regardless of the value of x.
At the point x = -2, the function experiences a discontinuity, because the two equations that define it have different values at this point. The function is not differentiable at this point, because it does not have a well-defined tangent line.
The domain of the function is the set of all real numbers, because there are no restrictions on the values of x that are allowed.
Therefore, The range of the function is the set of all real numbers greater than or equal to -2, because the lowest possible value of the function is -2, which occurs at x = 2.

The trapezoid A’B’C’D is a dilation of the trapezoid ABCD. What is the scale factor of the dilation?
Simplify your answer and write it as a proper fraction, an improper fraction, or a whole number.
PLEASE LOOK AT PICTURE!!!!!!
All corresponding side lengths have a ratio of [tex]\frac{1}{3}$[/tex] or less, we can conclude that the scale factor of the dilation is less than or equal to [tex]\frac{1}{3}$[/tex]
How to find factor of dilation?We can use the distance formula to find the length of the sides of both quadrilaterals, and then find the ratio of corresponding side lengths to determine the scale factor of the dilation.
Let's start with the original quadrilateral ABCD. The length of AB is:
[tex]$\sqrt{(9 - (-3))^2 + (3 - 0)^2} = \sqrt{12^2 + 3^2} = \sqrt{153}$[/tex]
Similarly, the lengths of BC, CD, and DA are:
[tex]BC: $\sqrt{(9 - 9)^2 + (9 - 3)^2} = 6$[/tex]
[tex]CD: $\sqrt{(-3 - 9)^2 + (3 - 9)^2} = \sqrt{144 + 36} = \sqrt{180} = 6\sqrt{5}$[/tex]
[tex]DA: $\sqrt{(-3 - (-3))^2 + (3 - 0)^2} = 3$[/tex]
Now, let's find the corresponding side lengths of the dilated quadrilateral A'B'C'D'. The length of A'B' is:
[tex]$\sqrt{(3 - (-1))^2 + (1 - 0)^2} = \sqrt{16 + 1} = \sqrt{17}$[/tex]
Similarly, the lengths of B'C', C'D', and D'A' are:
[tex]B'C': $\sqrt{(3 - 3)^2 + (3 - 1)^2} = 2$[/tex]
[tex]C'D': $\sqrt{(-1 - 3)^2 + (1 - 3)^2} = \sqrt{16 + 4} = \sqrt{20} = 2\sqrt{5}$[/tex]
[tex]D'A': $\sqrt{(-1 - (-3))^2 + (1 - 0)^2} = \sqrt{4 + 1} = \sqrt{5}$[/tex]
Now we can find the ratio of corresponding side lengths:
[tex]$\frac{\text{length of A'B'}}{\text{length of AB}} = \frac{\sqrt{17}}{\sqrt{153}} = \frac{\sqrt{17} \cdot \sqrt{153}}{153} \approx 0.821$[/tex]
[tex]$\frac{\text{length of B'C'}}{\text{length of BC}} = \frac{2}{6} = \frac{1}{3}$[/tex]
[tex]$\frac{\text{length of C'D'}}{\text{length of CD}} = \frac{2\sqrt{5}}{6\sqrt{5}} = \frac{1}{3}$[/tex]
[tex]$\frac{\text{length of D'A'}}{\text{length of DA}} = \frac{\sqrt{5}}{3}$[/tex]
Since all corresponding side lengths have a ratio of [tex]\frac{1}{3}$[/tex] or less, we can conclude that the scale factor of the dilation is less than or equal to [tex]\frac{1}{3}$[/tex]. To find the exact scale factor, we can choose any two corresponding side lengths and take their ratio.

The number of bacteria in a culture is given by the function
n(t)=90e^0.15t
(a) What is the relative rate of growth of this bacterium population?
Your answer is ---------percent
(b) What is the initial population of the culture (at t=0)?
Your answer is---------
(c) How many bacteria will the culture contain at time t=5?
Your answer is----------
(a) The relative rate of growth of the bacterium population is 15% per unit time; (b) the initial population of the culture is 90 bacteria; (c) the culture will contain approximately 239 bacteria at time t=5.
(a) The relative rate of growth of the bacterium population can be calculated by taking the derivative of the function n(t) with respect to t and then dividing it by the value of n(t) at that point, which gives:
relative rate of growth = (dn/dt) / n(t)
= (0.15 * 90[tex]e^0.15t[/tex]) / (90[tex]e^0.15t[/tex])
= 0.15
Therefore, the relative rate of growth is 15%.
(b) The initial population of the culture at t=0 is given by plugging in t=0 in the function n(t):
n(0) = 90[tex]e^0.15[/tex]*0
= 90
Therefore, the initial population of the culture is 90.
(c) The number of bacteria in the culture at time t=5 can be found by plugging in t=5 in the function n(t):
n(5) = 90[tex]e^0.15[/tex]*5
= 385.97 (rounded to two decimal places)
Therefore, the culture will contain approximately 385.97 bacteria at time t=5.

Trigonometric Ratios of Particular Angles: What Are They?It is possible to calculate trigonometric ratios for various orientations. However, we memories the trigonometric ratios of a few particular angles, such as 0°, 30°, 45°, 60°, and 90°, to make computations easier. The numbers of the ratios at these angles can be found in the trigonometric ratios table.
The Pythagorean formula can be applied to the illustration to determine the length of the third side:
c²= a²+ b²
c²= 8² + √(17)²
c²= 64 + 17
c² = 81
c = 9
We can now calculate the trigonometry ratios of angles K and L:
cos(K) = adjacent/hypotenuse = √(17)/9
sin(L) = opposite/hypotenuse = 8/9
Using the same hypotenuse number of 9, we can calculate both cos(K) and sin(L) as follows:

14. (Find LCM of) : ax² - (a² + ab)x+ a²b, bx² - (b² + bc)x + b²c and cx² - (c² + ac)x+ c²a
Answer:
Step-by-step explanation:
To find the LCM of the given expressions, we need to factor each expression completely and then find the product of the highest powers of all the factors.
ax² - (a² + ab)x + a²b can be factored as:
ax² - (a² + ab)x + a²b = a(x - b)(x - a)
bx² - (b² + bc)x + b²c can be factored as:
bx² - (b² + bc)x + b²c = b(x - c)(x - b)
cx² - (c² + ac)x + c²a can be factored as:
cx² - (c² + ac)x + c²a = c(x - a)(x - c)
Now, the LCM is the product of the highest powers of all the factors.
The highest power of a is a², the highest power of b is b², and the highest power of c is c². So, the LCM is:
LCM = a²b²c²(x - a)(x - b)(x - c)
Therefore, the LCM of ax² - (a² + ab)x + a²b, bx² - (b² + bc)x + b²c and cx² - (c² + ac)x + c²a is a²b²c²(x - a)(x - b)(x - c).

Answer:
linear
Step-by-step explanation:
this is a linear function!
linear functions follow y = mx+b, where m is the slope and b is the y-intercept
let's write our y = mx+b equation
for each value that x increases, y increases by DOUBLE that amount. slope is y/x, so since y increases by 2 and x increases by 1, the slope is 2/1 which is 2.
the y-intercept is where the line passes the x axis, or when x is 0. in this table, it gives you your y-intercept, which is -6
your equation is y=2x+(-6); which simplified to y=2x-6
if you plug in the y and x values, you'll get the same thing. i hope this helped!

Average rate of changeThe average rate of change is defined as ...
AROC(g) = (g(b) -g(a))/(b -a)
We can evaluate this directly, or we can simplify it a bit first.
AROC = ((3b² +3) -(3a² +3))/(b -a)
= (3b² -3a²)/(b -a)
= 3(b -a)(b +a)/(b -a)
= 3(b +a)
Interval [-9, 4]The AROC on the interval [a, b] = [-9, 4] is then ...
AROC = 3(4 +(-9)) = 3(-5)

Example 1
Solve 3x − 5 ≤ 3 − x.
Solution
We start by adding both sides of the inequality by 5
3x – 5 + 5 ≤ 3 + 5 − x
3x ≤ 8 – x
Then add both sides by x.
3x + x ≤ 8 – x + x
4x ≤ 8
Finally, divide both sides of the inequality by 4 to get;
x ≤ 2
Example 2
Calculate the range of values of y, which satisfies the inequality: y − 4 < 2y + 5.
Solution
Add both sides of the inequality by 4.
y – 4 + 4 < 2y + 5 + 4
y < 2y + 9
Subtract both sides by 2y.
y – 2y < 2y – 2y + 9
Y < 9 Multiply both sides of the inequality by −1 and change the inequality symbol’s direction. y > − 9
Solving linear inequalities with subtraction

Which best describes why it is helpful to know the slant height of a pyramid to find its surface area?
Responses
1)Knowing the slant height helps because it represents the height of the triangle that makes up the base. So, the slant height helps you to find the area of the base.
2)Knowing the slant height helps because it represents the height of the rectangle that makes up each lateral face. So, the slant height helps you to find the area of each lateral face.
3)Knowing the slant height helps because it represents the height of the triangle that makes up two of the lateral faces. So, the slant height helps you to find the area of those two lateral faces.
4)Knowing the slant height helps because it represents the height of the triangle that makes up each lateral face. So, the slant height helps you to find the area of each lateral face.
Therefore, knowing the slant height is important in calculating the lateral area of the pyramid, which is one component of the total surface area.
by the question.
Option 2 is the correct response. Knowing the slant height is helpful because it represents the height of the rectangle that makes up each lateral face of the pyramid. The lateral faces are made up of triangles and rectangles, and the slant height is used to find the height of these rectangles.
Knowing the slant height helps because it represents the height of the rectangle that makes up each lateral face. So, the slant height helps you to find the area of each lateral face. The formula for the lateral area of a pyramid involves the slant height, the perimeter of the base, and the apothem (the distance from the center of the base to the midpoint of a side). Once you know the lateral area, you can add it to the area of the base to find the total surface area of the pyramid.
The slant height of a pyramid is the height of each triangular lateral face, which is an essential component in calculating the lateral surface area of a pyramid. Knowing the slant height is used in the formula for finding the lateral area of a pyramid, which is the sum of the areas of all the triangular lateral faces. Additionally, the base area of the pyramid is also needed to find the total surface area of the pyramid. So, knowing the slant h
