Answer:
C. SSS
Step-by-step explanation:
[tex] \frac{AB}{SQ} = \frac{AC}{SR} = \frac{BC}{QR} = 2 [/tex]
Thus, the ratio of the corresponding side lengths of both triangles are equal. This implies that all three corresponding side lengths of both triangles are proportional to each other.
Consequently, based on the SSS Criterion, we can conclude that both triangles are similar to each other.

Which function is positive for the entire interval (-3, -2]?
Graph 2 represents that the function is positive for the entire interval [-3,-2].
What is a function?A function is a relation in which each possible input value leads to exactly one output value. We say “the output is a function of the input.” The input values make up the domain, and the output values make up the range.
We are given four different graphs for different functions. We have to find the graph that is positive for the entire interval [-3,-2].
We make the following observation from the given graphs.
1. In graph 1 the function has a value of 0 at -3 and the value decreases from -3 to -2. Thus the function is negative in the given interval.
2. In graph 2, it can be clearly seen that the function has a positive value, through the entire given interval.
3. In graph 3, the function shows negative value entirely in the given interval.
4. In graph 4, the function exhibits both positive and negative value in the given interval and in not positive in the entire interval.
Thus, the function in graph 2 is positive for the entire interval [-3,-2].

I need someone really good at math to help me please!! A home is purchased for $394,000 with a 14% down payment. Find the monthly payment if the mortgage has a 7.2% interest rate for 30 years.
9514 1404 393
Answer:
$2300.01
Step-by-step explanation:
The down payment is 14% of $394,000, so is ...
0.14 × $394,000 = $55,160
This means the principal amount of the loan is ...
$394,000 -55,160 = $338,840
__
The amount of the monthly loan payment is given by the amortization formula ...
A = P(r/12)/(1 -(1 +r/12)^(-12t))
where P is the principal amount, r is the annual interest rate, and t is the number of years. Filling in the values, we have ...
A = $338,840(0.072/12)/(1 -(1 +0.072/12)^(-12·30))
= $338,840(0.006)/(1 -(1.006^-360)) = $2300.01
The monthly payment is $2300.01.

One method for estimating the availability of office space in large cities is to conduct arandom sample of offices, and calculate the proportion of offices currently being used. Suppose that realestate agents believe that p = 0.70 of all offices are currently occupied, and decide to take a sample toassess their belief. They are considering a sample size of n = 40.a)
a. Show that this sample size is large enough to justify using the normal approximation to thesampling distribution of p.
b. What is the mean of the sampling distribution of p if the real estate agents are correct?
c. What is the standard deviation of the sampling distribution of p if the real estate agents arecorrect?
d. If the real estate agents are correct, what is the probability that a sample proportion, p,would differ from p = 0.70 by as much as 0.05?
Answer:
a) Since np >= 5 and n(1-p) >= 5, the approximation is justified
b) 0.7
c) 0.0725
d) 0.5098 = 50.98% probability that a sample proportion, p,would differ from p = 0.70 by as much as 0.05
Step-by-step explanation:
We use the normal distribution and the central limit theorem to solve this question.
Normal probability distribution
When the distribution is normal, we use 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.
Central Limit Theorem
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
In this question, we have that:
[tex]p = 0.7, n = 40[/tex]
a. Show that this sample size is large enough to justify using the normal approximation to thesampling distribution of p.
We need that: np >= 5, n(1-p) >= 5. So
np = 40*0.7 = 28 > 5
n(1-p) = 40*0.3 = 12 > 5
Since both conditions are satisfied, the approximation is justified.
b. What is the mean of the sampling distribution of p if the real estate agents are correct?
This is [tex]\mu = p = 0.7[/tex]
c. What is the standard deviation of the sampling distribution of p if the real estate agents are correct?
This is [tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.7*0.3}{40}} = 0.0725[/tex]
d. If the real estate agents are correct, what is the probability that a sample proportion, p,would differ from p = 0.70 by as much as 0.05?
This is the pvalue of Z when X = 0.7 + 0.05 = 0.75 subtracted by the pvalue of Z when X = 0.7 - 0.05 = 0.65. So
X = 0.75
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.75 - 0.7}{0.0725}[/tex]
[tex]Z = 0.69[/tex]
[tex]Z = 0.69[/tex] has a pvalue of 0.7549
X = 0.65
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.65 - 0.7}{0.0725}[/tex]
[tex]Z = -0.69[/tex]
[tex]Z = -0.69[/tex] has a pvalue of 0.2451
0.7549 - 0.2451 = 0.5098
0.5098 = 50.98% probability that a sample proportion, p,would differ from p = 0.70 by as much as 0.05

Parts of New Orleans lie 0.5 meter below sea level. After d days of rain, the equation w=0.3d ± 0.5 represents the water level w in meters. Find the zero, and explain what it means in the context of this situation.
Answer:
[tex]w = - 0.5[/tex]
Step-by-step explanation:
Given
[tex]w = 0.3d - 0.5[/tex] [The correct equation]
Required
Find and interpret the 0
To do this, we set [tex]d = 0[/tex]
Substitute 0 for d in [tex]w = 0.3d - 0.5[/tex]
[tex]w = 0.3 * 0 - 0.5[/tex]
[tex]w = 0 - 0.5[/tex]
[tex]w = - 0.5[/tex]
This means that the level of rain is 0.5m below the sea at day 0

Answer: x=70, y=20
Step-by-step explanation:
From the equilateral triangle, we know that 2y+10=x-y, as all sides must measure the same length.
From the isosceles triangle, we know that x° is 70°, because all triangles must add up to 180°.
70-y=2y+10
Solve for this, and y=20
NOTE: Angles not necessarily drawn to size . what is x?
Answer: 45
Step-by-step explanation: 160-115= 45 you do this because the angles are across the vertex from each other.
Answer:
X=45
Step-by-step explanation:
Method 1 ( the long one)
So AED and CEB are vertical angles, that means that the are the same and have the same value.
So 115 plus x equal 160.
115 + x = 160
from there we just have to subtract 115 from both sides to get x by itself.
115 + x = 160
-115 -115
_________________
x=45
Method 2 (short one
If you know that those are vertical angles, then just subtract 115 from 160 and there you go. You get 45.

A fair six-sided number cube is rolled 60 times. What is the probability that fewer than 10% of the rolls are a five?
Find the z-table here.
Answer:
0.0823 = 8.23% probability that fewer than 10% of the rolls are a five
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal probability distribution
When the distribution is normal, we use 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.
Central Limit Theorem
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex].
A fair six-sided number cube is rolled 60 times.
This means that [tex]n = 60[/tex]
Rolls that are a five:
For each roll, there are 6 possible outcomes: 1, 2, 3, 4, 5 or 6. So the probability of rolling a five is:
[tex]p = \frac{1}{6} = 0.1667[/tex]
The distribution has mean and standard deviation:
[tex]\mu = p = 0.1667[/tex]
[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.1667*(1-0.1667)}{60}} = 0.0481[/tex]
What is the probability that fewer than 10% of the rolls are a five?
This is the pvalue of Z when X = 0.1. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.1 - 0.1667}{0.0471}[/tex]
[tex]Z = -1.39[/tex]
[tex]Z = -1.39[/tex] has a pvalue of 0.0823
0.0823 = 8.23% probability that fewer than 10% of the rolls are a five
Answer: 0.082
