Answer:

  3/2

Step-by-step explanation:

The scale factor is the ratio of corresponding side lengths.

  larger/smaller = (21/2)/7 = 21/14 = 3/2

The scale factor is 3/2.

Step-by-step explanation:

First

since its follow the pattern Intercept Max... Intercept Min...

Its a positive sine graph

Asin(B(x-0))<0.25

A=1

B=2π/period

period From the graph = 2π

B=2π/2π

B=1

Sin(x)<0.25

I'd go with C.

Answer: A) Domain: All real numbers , Range: All real numbers

Step-by-step explanation: Since the line of the graph continued to infinity, the answer for both domain (goes from Left to right) and range (goes up to down) would be all real numbers

Answer:

The inverse function is [tex]y = -\frac{x}{4}[/tex]

Step-by-step explanation:

Inverse of a function:

To find the inverse of a function, we exchange x by y, then we isolate y.

y = -4x

Finding the inverse:

[tex]x = -4y[/tex]

[tex]4y = -x[/tex]

[tex]y = -\frac{x}{4}[/tex]

So

The inverse function is [tex]y = -\frac{x}{4}[/tex]

Answer:

Angles EAB = 85 degrees

Step-by-step explanation:

This my answer with the working steps...

Answer:

19

Step-by-step explanation:

point y is 90

x is 3x - 5

w is 2x

so

3x - 5 + 2x = 90

5x - 5 = 90

5x = 95

x = 19

Answer:

  (c)  π/2

Step-by-step explanation:

We know the sine of an angle is the cosine of its complement, and vice versa. The complement of angle x is (π/2-x), so ...

  sin(π/2 -x) = cos(x)

This is shown by the attached graph.

Answer:

The correct option depends on the ACT z-score. If it's higher than 1.47 the best option is the ACT while if it's lower the best option is the SAT.

Step-by-step explanation:

Z-score:

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

In this question:

Whichever test has the higher z-score should be taken.

SAT scores are normally distributed and in the state of Ohio in 2017, the mean was 1149 with a standard deviation of 212. To get accepted into Yale, you need an SAT of 1460.

This means that [tex]X = 1460, \mu = 1149, \sigma = 212[/tex]

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1460 - 1149}{212}[/tex]

[tex]Z = 1.47[/tex]

Z-score for the ACT:

We don't have the mean.

But the correct option depends on the ACT z-score. If it's higher than 1.47 the best option is the ACT while if it's lower the best option is the SAT.

the answer is A

Step-by-step explanation:

Answer:

Area is 195 in

Step-by-step explanation:

I did this assignment :D

Answer:

Part A: 4,300 ≥ 2500 + 0.12s

Part B: Less than or equal to $15,000

Part C: In the image

Step-by-step explanation:

For Part A: The total needs to be at least 4,300. So 4,300 is greater than or equal to how much she earns. 2,500 is the base pay, and it is added to 0.12s, which represents 12% of sales (s).

For Part B:

Using the inequality, solve for s

4,300 ≥ 2500 + 0.12s

Subtract 2500 from both sides

1800 ≥ 0.12s

Now divide both sides by 0.12 to isolate s

15000 ≥ s

So sales must be less than or equal to 15000.

Part C:

Answer:

-9/10

Step-by-step explanation:

The slope of line C is [tex]m=\frac{8-(-2)}{3-(-6)}=\frac{10}{9}[/tex].

The slope of any line perpendicular to line C is the negative (opposite) reciprocal of this slope.

The slope of line F is [tex]-\frac{9}{10}[/tex].

Answer:

i think it would be d

Step-by-step explanation:

the median is just the middle of the numbers, it doesnt say which is the hardest question though

hope this helps.

EDCB is a rectangle, so:

ED = BC = 12

DC = EB = 29

We know that,

= AB = AE + EB

= 34 = AE + 29

= 34 - 29 = AE

= 5 = AE

Now, in triangle EAD, by pythagonas theoram:

= H² = P² + B²

= H² = 5² + 12²

= H² = 25 + 144

= H = √169

= H = 13

So, AD = 13 cm

Answer:

  x = 1

Step-by-step explanation:

The graph of f(x) has a relative minimum where its first derivative (f'(x)) is zero and its second derivative (f''(x)) is positive. (Function f(x) is concave upward when f''(x) > 0.) Since the second derivative is the slope of the first derivative, this means the local minimum will be at the x-value where f'(x) = 0 and is crossing the x-axis from below.

The graph of f'(x) shows a local minimum at x = 1.

__

Desmos does not allow us to define f'(x) directly, so we have called it f₁(x). The function f(x) is the integral of that—shown as the dashed orange line. We wanted you to see the f(x) curve so you could see it has a local minimum at x=1.

Answer: 113.0cm²

Step-by-step explanation:

The surface area if a square is calculated as:

= 4πr²

where, radius = 3cm

Surface area = 4πr²

= 4 × 3.14 × 3²

= 4 × 3.14 × 9

= 113.04

= 113.0cm²

Therefore, the surface area is 113.0cm²

Answer:

John: 19

Jack: 9

Step-by-step explanation:

Answer:

Jack = 9

John = 19

Step-by-step explanation:

Let  the  number  that  Jack  solved  =  N

Then John solved  2N +  1

So

N  + 2N +  1  =   28

3N   =  28  -  1

3N  =   27

N =  27  / 3    =  9   =   number Jack solved

2(9) + 1   =  19  =  number John solved

Answer:

D. 8

Step-by-step explanation:

set up a proportion

3/20 = x/50

to get from 20 to 50 you have to multiply by 2.5

so multiply the top number (3) by 2.5 to find x

this comes out to 7.5 which you then round up to 8

Step-by-step explanation:

Answer:

0.0939 = 9.39% probability that there will be exactly 4 sets of twins.

Step-by-step explanation:

For each birth, there is only two possible outcomes. Either it results in twins, or it does not. The probability of a birth resulting in twins is independent of any other birth. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

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

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

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

And p is the probability of X happening.

The probability that a birth will result in twins is 0.017.

This means that [tex]p = 0.017[/tex]

120 births:

This means that [tex]n = 120[/tex]

The probability that there will be exactly 4 sets of twins is?

This is P(X = 4).

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

[tex]P(X = 4) = C_{120,4}.(0.017)^{4}.(0.983)^{116} = 0.0939[/tex]

0.0939 = 9.39% probability that there will be exactly 4 sets of twins.

Answer:

4.

Step-by-step explanation:

the difference means -.

between a number means use a variable (x) to substitute. so now you have the difference between x and 6 is to. is just means equals so you would set it up like this 6-x=2. you can make this easier by just asking yourself. what number plus 2 equals six? the answer would be 4. 4+2=6-->6-4=2.
