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°.

the answer is 512

Answer:

x = 8

y = 14

Step-by-step explanation:

2x + 6 = 4x - 10 (Corresponding angles so they're equal)

2x - 4x = -10 - 6

-2x = -16

x = 8

2x + 6 + 13y - 24 = 180 (Supplementary angles so they add up to 180)

2(8) + 6 + 13y - 24 = 180

16 + 6 + 13y - 24 = 180

13y - 2 = 180

13y = 182

y = 14

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:

Answer:

5,270

Step-by-step explanation:

155,000 x 3.4%

Answer:

5270

Step-by-step explanation:

multiply 155,000 by 3.4 and then divide it by 100

155,000 x 3.4=527,000

527,00 divided by 100 = 5270

Answer:

yes

Step-by-step explanation:

Yes it is, assuming we decide to use the Pythagorean Theorem to find the hypotenuse (10) it'll be possible considering the formula is c²=√a²+b²

(c being the longest side of the triangle)

a= 6 and b= 8

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.

I hope this helps! Sorry if its doesn't though:( I hope you have a amazing day! And maybe you could mark this brainly?

Answer:

mplete results in the Gradebook and Mastery Dashboards; Start a class ... and a cylinder. What is the volume, in cubic inches, of the crayon balloon? 14 ... Which measurement is CLOSEST to the distance Jen walks to school each morning? 22 ... C-G.2.1.3. Q.Michael stacks 14 14 14 identical disks to form a cylinder.

Step-by-step explanation:

The volume of the cylinder will be 24.72 in³.

In mathematics, a cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance.

Given that, the 14 identical disks are stacked to form a cylinder, each disk is 1/4 inch thick, and their diameter is 3 inches, we need to find the volume of the cylinder,

So, here we can say that the height of the cylinder is the sum of the thickness of all the disks,

So, height = 1/4 x 14 = 3.5 inches.

The volume of the cylinder = π × radius² × height.

= 3.14 × 1.5² × 3.5 [radius = diameter / 2]

= 3.14 × 2.25 × 3.5

= 24.72 in³

Hence, the volume of the cylinder will be 24.72 in³.

Answer:

The standard deviation of the comparison distribution is 0.5657.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

In this question:

Standard deviation of the population is 8, sample of 200. So

[tex]s = \frac{8}{\sqrt{200}} = 0.5657[/tex]

The standard deviation of the comparison distribution is 0.5657.
