Step-by-step explanation:

Answer:

286 centimeters³

Step-by-step explanation:

identify variable:   L=11    W=2      H=13

use volume of a rectangular prism formula:   V=LWH

substitute variables into formula:         V=(11)(2)(3)

V=286 cm³

Answer: D. Park B showed faster growth between 2009 and 2014, at an average rate of 120 swallows per year.

Step-by-step explanation:

I did the math

The Park B showed faster growth between 2009 and 2014, at an average rate of 100 swallows per year i.e. option A.

The average rate is defined as a measure of how much the function changed per unit, on average, over that interval.

We have,

x is time, in years, since 2005,

and,

f(c) is population in hundreds.

Now,

For Park A,

at x = 4 ,

Swallows Population = 2370

and,

at x = 9,

Swallows Population = 2870

So,

Average Rate [tex]=\frac{2870 - 2370}{10} = 50[/tex]

Now,

For Park B,

at x = 4,

Swallows Population = 2200

and,

at x = 9,

Swallows Population = 2800

So,

Average Rate [tex]=\frac{2800- 2200}{10} = 60[/tex]

So,

Difference in average rate = 60 - 50 = 10

From the average rate of of both park A and Park B,

We can see that,

Park B has faster growth rate of 100 per year.

Hence, we can say that the Park B showed faster growth between 2009 and 2014, at an average rate of 100 swallows per year i.e. option A.

Answer:

Step-by-step explanation:

Angles BGC and FGE share vertex G and are composed of opposite rays. This makes them vertical angles.

Angle BGC and CGD make up a right angle, so they are complementary. That makes angle BGC equal to 90° -40° = 50°.

Vertical angles have the same measure, so ∠FGE = 50°.

Answer:

x = 7

Step-by-step explanation:

Distribute the 2 on the right and the -1 on the left: 13 - 2x - 2 = 2x + 4 + 3x

Combine like terms on each side of the equation: 11 - 2x = 5x + 4

Add 2x to both sides, and subtract 4 from each side: 7 = 7x

Divide both sides by 7: x = 7

Step-by-step explanation:

Answer:

0.2333 = 23.33% probability this student's score will be at least 2100.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution, and conditional probability.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

SAT scores (out of 2400) are distributed normally with a mean of 1490 and a standard deviation of 295.

This means that [tex]\mu = 1490, \sigma = 295[/tex]

In this question:

Event A: Student was recognized.

Event B: Student scored at least 2100.

Probability of a student being recognized:

Probability of scoring at least 1900, which is 1 subtracted by the pvalue of Z when X = 1900. So

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

[tex]Z = \frac{1900 - 1490}{295}[/tex]

[tex]Z = 1.39[/tex]

[tex]Z = 1.39[/tex] has a pvalue of 0.9177

1 - 0.9177 = 0.0823

This means that [tex]P(A) = 0.0823[/tex]

Probability of a student being recognized and scoring at least 2100:

Intersection between at least 1900 and at least 2100 is at least 2100, so this is 1 subtracted by the pvalue of Z when X = 2100.

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

[tex]Z = \frac{2100 - 1490}{295}[/tex]

[tex]Z = 2.07[/tex]

[tex]Z = 2.07[/tex] has a pvalue of 0.9808

This means that [tex]P(A \cap B) = 1 - 0.9808 = 0.0192[/tex]

What is the probability this student's score will be at least 2100?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0192}{0.0823} = 0.2333[/tex]

0.2333 = 23.33% probability this student's score will be at least 2100.

Answer:

The people who said Yes to having a pet in their home is greater

Step-by-step explanation:

We are asked to compare 18% and 14/25. Let's get them to their lowest common denominator:

18% = 18/100

14/25 * 4 = 56/100

18/100 is clearly much less than 56/100. If you don't want to write all this out, you can also eyeball that 14/25 is over half, whereas 18% is not close to half.
