Answer:

1/6(x) = 16

Step-by-step explanation:

You can just solve for x which goes as follows:

6 * 1/6 = 6 * 16 - Multiply both sides by 6.

x = 96

Answer:

x=96

Step-by-step explanation:

To figure out the weight of the person on the moon we would need to take their weight and divide by 6. we don't know the weight so it's x. We know the final weight so the x divided by 6 should be 16.

this translates to:

x/6=16

x=16*6

x=96

[tex]\textsf{b)} \quad -\dfrac{3\sqrt{13}}{13}[/tex]

Step-by-step explanation:

Trigonometric ratios

[tex]\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}[/tex]

where:

[tex]\textsf{If}\; \tan(\theta)=-\dfrac{2}{3} \implies \sf O=2 \; \textsf{and} \; A=3.[/tex]

Use Pythagoras Theorem to calculate the length of the hypotenuse:

[tex]\sf \implies O^2+A^2=H^2[/tex]

[tex]\implies \sf H=\sqrt{O^2+A^2}[/tex]

[tex]\implies \textsf{H}=\sqrt{2^2+3^2}[/tex]

[tex]\implies \textsf{H}=\sqrt{13}[/tex]

Therefore, substituting the values of A and H into the cosine ratio:

[tex]\implies \cos \theta=\dfrac{3}{\sqrt{13}}[/tex]

[tex]\implies \cos \theta=\dfrac{3}{\sqrt{13}}\cdot \dfrac{\sqrt{13}}{\sqrt{13}}[/tex]

[tex]\implies \cos \theta=\dfrac{3\sqrt{13}}{13}[/tex]

As the terminal side of the angle is in Quadrant II, and cosine is negative in Quadrants II and III, the exact value of cos(θ) is:

[tex]\implies \cos \theta=-\dfrac{3\sqrt{13}}{13}[/tex]

The weight represents the 42nd percentile.

8.3,6.5,6,6,5,4,6.7,6.5,8: 1,9.2,6.4,8 0,6.8,9.0,8.7,9.3,8.0

The ascending order of the data is

5.4,6.0,6.4,6.5,6.5,6.7,6.8,8.0,8.0,8.1,8.3,8.7,9.0

The domain is all values of x that makes the given expression undefined.

The given expression is;

y = (1 - 7x)/8 - 1/|3x - 15|

To find the value of x that will make the expression undefined, it means that we will equate the denominator to zero to get;

|3x - 15| = 0

Thus;

Answer:

[tex]2\sqrt{5}[/tex]

Step-by-step explanation:

You can use the Pythagorean Theorem, which is [tex]a^{2}+ b^{2}= c^{2}[/tex]. So the the distance from -9 to -5 is 4 and the distance from 8 to 6 is 2.

So [tex]4^{2} +2^{2} =c^{2}[/tex]. Which equals [tex]20=c^{2}[/tex].

Then you square root [tex]c^{2}[/tex] to make it c, then you do that to the other side. So you have [tex]\sqrt{20}=c[/tex].

Which equals [tex]2\sqrt{5}[/tex].

Or you can use the Distance Formula, which is [tex]\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }[/tex].

The [tex]x_{1}[/tex] is -5 and the [tex]x_{2}[/tex] is -9. The [tex]y_{1}[/tex] is 6 and the [tex]y_{2}[/tex] is 8. When you plug that in you get [tex]\sqrt{(-9--5)^{2} +(8-6))^{2} }[/tex]. When you simplify that you get [tex]\sqrt{20}[/tex].

Answer:

360 million written in scientific notation is 3.6 × 108.

Step-by-step explanation:

The rate of change of the linear equation that has the given points on its graph is; -2.

The rate of change of a linear function can be determined by using the following formula:

Rate of change = change in y / change in x = y2 - y1 / x2 - x1.

Given the following points on a graph of a linear function:

​(−5​,4​) = (x1, y1)

​(−2​,−2​) = (x2, y2)

Plug in the values

Rate of change = change in y / change in x = (-2 - 4) / (-2 -(-5))

Rate of change = -6 / 3

Rate of change = -2 / 1

Rate of change = -2

Thus, the rate of change of the linear equation that has the given points on its graph is; -2.

Answer:

157.41

Step-by-step explanation:

It can be identified that, given the figure, there is a rectangle and 2 semicircles.

Let's find the area of the rectangle first: A=L*w

Plugging in the given values => A=7.5*15.1 which equals 113.25.

Now the area for the semicircles: 1/2(3.14*r^2)

First, we need to find the radius. To find the radius, you just have to divide the diameter by 2. So, 7.5/2=3.75.

We can plug square the radius which is 3.75 and plug it into the formula: 1/2(3.14*3.75^2)=>22.078125.

22.078125 is the area of only one semicircle so we need to multiply it by 2 because we have two semicircles. So, we get 44.15625.

Finally, we can add them all up to find the total area of the figure: 113.25+44.15625=157.40625.

Rounding to the nearest hundredth=>157.41

The slope of line: 1. m= 6 , 2. m= -6 , 3. m= 2.5,  4. m= .5

The slope of the line :

In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.

The net change in the y-coordinate is represented by Δy and the net change in the x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,

m = change in y/change in x = Δy/Δx

Where “m” is the slope of a line.

Tan θ = Δy/Δx can also represent the slope of the line

So, tan θ to be the slope of a line.

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The letter ‘ m’ usually represents the slope.

If P(x1,y1) and Q(x2,y2) are the two points on a straight line, then the slope formula is given by:

Slope,

m = Change in y-coordinates/Change in x-coordinates

m = (y2 – y1)/(x2 – x1)

Therefore, based on the above formula, we can easily calculate the slope of a line between two points.

In other terms, the slope of a line between two points is also said to be the rise of the line from one point to another (along the y-axis) over the run (along the x-axis). Therefore,

Slope, m = Rise/Run

1.

(-1,-1) & (0,5)

m = (y2 – y1)/(x2 – x1)

m = (5 – (-1)) /(0– (-1))

m = (5 +1)/(0 +1)

m = (6)/(1)

m = 6

2.

(3,5) & (4,-1)

m = (-1 – 5)/(4 – 3)

m = (-6)/(1)

m = -6

3.

(2,1)  & (4,6)

m = (6 – 1)/(4 – 2)

m = (5)/(2)

m = 2.5

4.

(-5,-2) & (3,2)

m = (2 – (-2))/(3 – (-5))

m = (2 +2/(3 +5)

m = (4)/(8)

m = (2/(4)

Using the binomial distribution, there is a 0.1094 = 10.94% probability that exactly 20 adults received a flu vaccine.

For each adult, there are only two possible outcomes, either they received the vaccine or they did not. The probability of an adult receiving the vaccine is independent of any other adult, hence the binomial distribution is used to solve this question.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

For this problem, we have that:

The probability that exactly 20 adults received a flu vaccine is P(X = 20), hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 20) = C_{50,20}.(0.371)^{20}.(0.629)^{30} = 0.1094[/tex]
