Answer:
69
Step-by-step explanation:
First, find the angle FCB by subtracting 70 and 41 from 180. You should get 69. Then, because it says AD paralell EG, you could use the transversal FC to locate some angles. Fortunately, GFC and FCB are opposite interior angles, meaning they are equal in angle measure.

Which statement best describes the formation of metamorphic rocks?
A. Magma cools and crystallizes slowly beneath Earth’s surface.
B. Liquid lava erupts from a volcano and cools quickly at Earth’s surface.
C. Sand and gravel are deposited at the mouth of a river and, over time, form layers that solidify into rock.
D. Ancient sandstone beaches become buried deep beneath Earth’s surface, where they are exposed to extreme heat and pressure.
Answers
Answer:
D
Step-by-step explanation:
Metamorphic rock is formed when rocks or minerals are subjected to high heat and high pressure, or a combination of these two factors. Answer D is the only answer that explicitly describes a rock or mineral being subject to these two things, so therefore D is the best answer.

g Suppose 40% of the students in a university are baseball players. If a sample of 781 students is selected, what is the probability that the sample proportion of baseball players will be greater than 43%
Answers
Answer: 0.1271
Step-by-step explanation:
Let p= probability of the students in a university are baseball players.
Given: p= 0.40 , sample size : n= 781
The probability that the sample proportion of baseball players will be greater than 43% will be:
[tex]P(p>0.43)=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.43-0.41}{\sqrt{\dfrac{0.41(1-0.41)}{781}}}\\\\=P(Z>1.14)\ \ \ [Z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}]\\\\=1-P(Z<1.14)\\\\=1- 0.8729=0.1271[/tex]
Hence, the probability that the sample proportion of baseball players will be greater than 43% = 0.1271

Find three consecutive even integers if their sum, decreased by the third, equals -22.
Answers
Three consecutive even integers:
x, x + 2, x + 4
x + x + 2 + x + 4 - (x + 4) = -22
2x + 2 = -22
2x = -24
x = -12
X = -12
X + 2 = -10
X + 4 = -8
As per linear equation, the required three consecutive even integers those have a sum of - 22 are - 8, -10, - 12.
What is a linear equation?"An equation that has the highest degree of 1 is known as a linear equation. This means that no variable in a linear equation has an exponent more than 1. The graph of a linear equation always forms a straight line."
Let, three consecutive even integers are x, x+2, and x+4.
Therefore, sum of these three consecutive even integers is
= [x + (x + 2) + (x + 4)]
Given, the sum of the three consecutive even integers decreased by the third is - 22.
Now, [x + (x + 2) + (x + 4)] - (x + 4) = - 22
⇒ x + (x + 2) = - 22
⇒ 2x + 2 = - 22
⇒ 2x = -24
⇒ x = - 12
Now, x + 2 = - 12 + 2 = - 10
Similarly, x + 4 = - 12 + 4 = - 8
Therefore, required three consecutive even integers with a sum of - 22 are - 8, - 10, - 12.

Thunder is the sound caused by lightning. You hear thunder 5 seconds after a lightning strike. The speed of sound is about 1225 kilometers per hour. About how many miles away was the lightning?
Answers
Answer:
it is 1.05
Step-by-step explanation:
The lightning was 1.7 kilometer away.
What is speed?In unit time, the distance covered by any object is called speed.
In mathematical term, Speed is express as S=D/T,
where S=speed, D=distance, T= time.
Given that,
The speed of sound = 1225 kilometers per hour
The speed of sound = 340.277 meter/second
Also, the time after thunder heard = 5 seconds
To find distance, use formula distance = speed × time,
Distance = 340.277 × 5
= 1701.3 meter
= 1.7 kilometer
The lightning was 1.7 kilometer away.

Will, an art student, randomly sampled oil paintings in a museum. He wanted to find out how many oil paintings in the museum contained the color ultramarine blue. The proportion of paintings that were created using the color ultramarine blue was 0.17, with a margin of error of 0.02. Construct a confidence interval for the proportion of oil paintings that contained ultramarine blue.
Answers
Answer:
The confidence interval is [tex]0.15 < p < 0.19[/tex]
Step-by-step explanation:
From the question we are told that
The sample proportion is [tex]\^ p = 0.17[/tex]
The margin of error is [tex]E = 0.02[/tex]
Generally the confidence interval for the proportion of oil paintings that contained ultramarine blue is mathematically represented as
[tex]\^ p - E < p < \^ p + E[/tex]
=> [tex]0.17 - 0.02 < p < 0.17 + 0.02[/tex]

A carpenter is building a rectangular room with a fixed perimeter of 180 ft. What are the dimensions of the largest room that can be built? What is its area?
Answers
Answer:
Answer: 45ft x 45ft
Step-by-step explanation:
we know that
Perimeter = 2(Length) + 2(Width)
180 = 2L + 2W
90 = L + W
90 - L = W
Area = Length *Width
= L(90 - L) → = 180L - L²
There are 2 different methods for solving (depending on which math course you are taking).
Calculus: find the derivative, set it equal to zero, and solve for L.
= 90L - L² → 0 = 90 - 2L → 2L = 90 → L = 45
Algebra: find the vertex.
= - L² + 90L → L = -b/2a → L = -90/2(-1) → L = 45
insert L it into the Perimeter equation to solve for W:
90 - L = W → 90 - 45 = W → W = 45
Answer: 45ft x 45ft

A local BBQ restaurants offers 2 side dishes with a lunch plate. There are 7 side dishes. How many choices of side dishes does a customer have
Answers
Step-by-step explanation:
This is a question that bothers combination. Combination has to do with selection.
When selecting r objects out of a pool of n objects, the number of ways this can be done is:
nCr = n!/(n-r)!r!
If a local BBQ restaurants offers 2 side dishes with a lunch plate, and there are 7 side dishes, the number of choices that the customer have is expressed as:
7C2 = 7!/(7-2)!2!
7C2 = 7!/(5)!2!
7C2 = 7*6*5!/5! * 2
7C2 = 7*6/2
7C2 = 42/2
7C2 = 21 choices
Hence the customer has 21 choices of side dishes to make
