Yes, it is proportional because the graph of these coordinates is a straight line and the ratios for [y] over [x] are all equivalent to one half.

Proportional relationships are relationships between two variables where their ratios are equivalent. A straight line represents a proportional relationship. Mathematically -

y = kx + c

(y - c)/x = k         [k is constant]

or

y = kx

k = y/x                [k is constant]

Given is the following data -

[x]  42.5      29.2     69.4

[y]   21.25     14.6      34.7

In order to find if the given coordinates represent proportional relationship, plot these coordinates on graph. If the by joining the coordinate points, we get a straight line, then it represents a proportional relationship. Graph is attached with the answer. It can be seen that its graph is a straight line and hence represents a proportional relationship.

Now, the ratio of [y] by [x] -

m = (21.25 - 14.6)/(42.5 - 29.2) = 6.65/13.3 - 0.5 = 1/2

Therefore, we can say that, Yes, it is proportional because the graph of these coordinates is a straight line and the ratios for [y] over [x] are all equivalent to one half.

b.  the probability that it lasted at least 12 days = 0·72575

c.  the probability that it lasted between 17 and 22 days  = 0.30567

d. 72% of all of these types of trials are completed within  13 days

(a)

The x follow normal distribution with mean standard deviation

X ~ N(15,5)

(b)

probability at least 12 days.

P(X≥12) = 1 - P(X ≤12)

            = 1 - P((X - μ)/б ≤ (12-15)/5 ]]

(c)

Probability at least between 16 & 21 days

P(16 < x < 21) = p( (16-15)/5 <  (X - μ)/б - (21-15)/5]

                     = p (0.2 < Z < 1.2 )

                     = p[Z < 1.2] - P[Z < 0.2]

This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability has been applied into mathematics to predict the likelihood of different events. Probability generally refers to the degree to which something is likely to occur. This fundamental theory of probability, which also applies to the probability distribution, can help you comprehend the possible outcomes for a random experiment. Before we can determine the probability that a certain event will occur, we must first know the total number of outcomes.

Step-by-step explanation: Use Substitution

The proof of △AED is congruent to △BEC

What is congruency?

Two figures or objects are congruent in geometry if they have the same shape and size, or if one has the same shape and size as its mirror counterpart. In more technical terms, two sets of points are said to be congruent if and only if one of them can be changed into the other by an isometry, which is a combination of rigid movements such as translation, rotation, and reflection. This implies that one item may be relocated and reflected (but not scaled) to perfectly align with the other. So two separate plane figures on a piece of paper are congruent if they can be cut out and then entirely matched up. It is OK to flip the paper over.

Given, △ABC is congruent to △BAD.

and △AEB is common in both, so

Answer:

[tex](f \circ g)(24)=-36[/tex]

Step-by-step explanation:

Given functions:

[tex]\begin{cases}f(x)=-9x+9\\g(x)=\sqrt{x+1}\end{cases}[/tex]

Function Composition is applying one function to the results of another.

The composite function (f o g)(x) means to substitute the function g(x) in place of the x in function f(x).  

Therefore (f o g)(24) means to substitute the result of g(24) in place of the x in the function f(x).

Calculate g(24) by substituting x = 24 into function g(x):

[tex]\begin{aligned}\implies g(24)&=\sqrt{24+1}\\&=\sqrt{25}\\&=5 \end{aligned}[/tex]

Therefore:

[tex]\begin{aligned}\implies (f \circ g)(24) & = f[g(24)]\\& = f(5)\\& = -9(5)+9\\&=-45+9\\&=-36\end{aligned}[/tex]

Answer:

(f∘g)(24) = -36

Step-by-step explanation:

We are given f(x) = -9x + 9 and  [tex]g(x)= \sqrt{x+1}[/tex].

We want to find (f∘g)(24).

This means that we first want to find g(24), then substitute the value of that into f(x).  

Start by substituting 24 for x in g(x).

[tex]g(24)= \sqrt{24+1}[/tex]

Add 24 and 1 together.

[tex]g(24)= \sqrt{25}[/tex]

Take the square root of 25.

g(24) = 5

Now, substitute 5 as x in f(x) = -9x + 9.

f(5) = -9(5) + 9

Multiply.

f(5) = -45 + 9

Add the numbers together.

f(5) = -36

f(5) in this case has the same value as (f∘g)(24)

This means that (f∘g)(24) = -36

Step-by-step explanation:

From the given figure the value of x is 6 and the measure of angle 3 is 57°.

From the given figure, m∠4=(20x+3)° and m∠6=(9x+3)°.

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.

22). From the given figure

m∠4+m∠6=180° (Coointerior angles sum is equal to 180°)

(20x+3)°+(9x+3)°=180°

⇒ 29x+6=180

⇒ 29x=174

⇒ x=6

m∠4=(20x+3)°=123°

m∠3+m∠4=180° (Adjacent angles sum is equal to 180°)

m∠3+123=180

m∠3=57°

23). From the given figure

m∠3=m∠6 (Alternate interior angles are congruent)

x+10 = 4x-20

⇒ 3x=30

⇒ x=10

Now, m∠6=4x-20

=20

m∠6+m∠8=180° (Adjacent angles sum is equal to 180°)

20+m∠8=180°

⇒ m∠8=160

Therefore, from the given figure the value of x is 6 and the measure of angle 3 is 57°.

The maximum length of each prism is equal to 7.99 centimeter.

First of all, we would determine the maximum surface area of this regular hexagonal prism by using this mathematical expression:

Maximum surface area (quantity) = Cost/unit price

Maximum surface area (quantity) = $11/$0.04

Maximum surface area (quantity) = 275 square centimeter (cm²).

Mathematically, the surface area of a regular hexagonal prism can be calculated by using this formula:

A = 6al + 3√3a²

Where:

Substituting the given parameters into the formula, we have;

275 = 6 × 4l + (3√3 × 4²)

275 = 24l + 48√3

24l = 275 - 48√3

Two or more expressions with an Equal sign is called as Equation.

Given that

Derrick measured wing length was 0.1 m

The wing that Leslie measured was (1/10) as long as the wing that derrick measured.

We need to measure how long is the wing that Leslie measured.

Multiply 0.1 by (1/10)

0.1×1/10

The vertex of the equation is (-3, 2). And the range will be the set of all real numbers equal to or larger than 2, written as:

y ≥ 2.

For an absolute value function of the form:

y = |x - a| + b

The vertex is a the point (a, b).

And the range (the set of the possible values of y that we can get with the function) will be the set of all real values equal or larger than b.

In this case, the absolute value function is:

y = |x + 3| + 2

Comparing it with the general one, we can see that the vertex is (-3, 2)
