Answer:
100.45
Step-by-step explanation:
Answer:
x = 96
Step-by-step explanation:
We have, 12.5%(x) = 12
or, 12.5/100(x) = 12
Multiplying both sides by 100 and dividing both sides by 12.5,
we have x = 12(100/12.5)
x = 96
Use the table that shows the results of a class poll.
Question
Yes
No
Do
you walk to school?
18% yes
82% no
Is there a pet in your home?
14
—— yes
25
11
—— no
25
Do you play on a sports team?
0.42 yes
0.58 no
Which category in the table shows the least portion of the class?
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?

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.
What is a cylinder?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.

Solve the following equations for x
13−(2x+2)=2(x+2)+3x
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

3.16 SAT scores: SAT scores (out of 2400) are distributed normally with a mean of 1490 and a standard deviation of 295. Suppose a school council awards a certificate of excellence to all students who score at least 1900 on the SAT, and suppose we pick one of the recognized students at random. What is the probability this student's score will be at least 2100
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:
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

1. In Part A of this lab, you will measure the dimensions (length, width, diameter) of several geometric shapes. a. Using a ruler, you measure the length of a rectangle to be 12.75 cm and the width to be 3.64 cm. Calculate the area of this rectangle (show work), reporting your answer to the correct number of significant figures.
Answer:
The area of this rectangle is 46.41 cm²
Step-by-step explanation:
Area of a rectangle:
The area of a rectangle of width w and length l is given by:
[tex]A = wl[/tex]
That is, the area of a rectangle is the multiplication of its width by its lengt.
In this question:
[tex]l = 12.75, w = 3.64[/tex]
So
[tex]A = wl = 3.64*12.75 = 46.41[/tex]
Width and length in centimeters, so the area is in square centimeters.
The area of this rectangle is 46.41 cm²

Answer:
vertical50°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°.
