Answer:
∠RPQ = 53°
Step-by-step explanation:
∠SPR and ∠RPQ are complementary, meaning that they add up to 90°. So,
∠SPR + ∠RPQ = 90°
We know that ∠SPR = 37°, so
37° + ∠RPQ = 90°
∠RPQ = 90° - 37°
∠RPQ = 53°

Step-by-step explanation:
Answer:
B
Step-by-step explanation:
it is important to note that 40/8 = 5.
A real number is one that can be found on the number line, and 5 can be.
A rational number can be made by dividing two integers (40 by 8 in this case).
5 is a whole number since it does not have a decimal/fractional part
an integer is a whole number which is positive/negative (5 is positive in this case)
Simplify using properties of operations and then factor the expressions using the GCF. (2g + 2) - (-4g - 7)
Answer:
3(2g + 3)
Step-by-step explanation:
We start out with the expression (2g + 2) - (-4g - 7).
Firstly, let's distribute the negative:
(2g + 2) - (-4g - 7)
2g + 2 + 4g + 7
Now, combine like terms:
2g + 4g + 7 + 2
6g + 9
The GCF stands for "Greatest Common Factor." In this case, we have to find the GCF between 6 and 9. What is the GCF of 6 and 9? It would be 3. So,
6g + 9
3(2g + 3)

Ramkin is going to flip a fair coin 100 times.
What is the best prediction for the number of times that the coin will land tails up?
Answer:
50 times
Step-by-step explanation:
You are going to flip a coin 100 times. There are 2 sides. So, what you would do is divide 100 by two because there are two sides. There is a 50% chance that the coin will land on heads, and a 50% chance it will land on tails.

What is the domain of the function shown on the graph?
Answer:
B. negative infinity < x < positive infinity
Step-by-step explanation:
When a question asks for the domain of a function, it is asking for all possible x-values, so we can rule out choice A since there are clearly x-values greater than 1. This graph shows arrows pointing left and downward, indicating that the graph continues past what we can see. This tells us that even though the x-values look like they end at -10 and 2, they continue further, so we can also rule out option C and option D. After these eliminations, we are left with choice B, which is a way of writing "All real numbers," and is the domain for all exponential functions, including this one.

Answer:
37/45 ≈ 0.822
Step-by-step explanation:
The formula for an exponential relation is ...
y = a·b^x
This question is asking for the value of b. It can be found by substituting the given values of x and y, and taking the ratio of the resulting equations.
90 = a·b^15
74 = a·b^16
Dividing the second equation by the first, we have ...
74/90 = (a·b^16)/(a·b^15)
74/90 = b
The decay factor is 74/90 = 37/45 ≈ 0.822
Answer:
37/45=0.822 this is my answer

A spherical container has a diameter of 100 centimeters. It is filled with a liquid that costs $80 per cubic centimeter. What is the total value of the liquid in the container?
Use 3.14 for π.
Enter your answer in the box to the nearest penny. will mark brainliest
Answer:
The total value of the liquid in the container is about $41,866,666.67.
Step-by-step explanation:
A spherical container has a diameter of 100 centimeters.
It is filled with a liquid that costs $80 per cubic centimeter.
And we want to determine the total value of the liquid in the container.
We can start by finding the volume of the container.
Since the container has a diameter of 100 centimeters, its radius if 50 centimeters.
The volume of a sphere is given by:
[tex]\displaystyle V=\frac{4}{3}\pi r^3[/tex]
Substitute. We will also use 3.14 for π. So:
[tex]\displaystyle =\frac{4}{3}(3.14)(50)^3=523333.33...\text{ cm}^3[/tex]
(Try not to round intermediate values.)
Since each cubic centimeter costs $80, we will multiply the total volume by the cost per cubic centimeter to find the total value. Thus, the total value is:
[tex](523333.\overline{3})(80)\approx \$41, 866, 666.67[/tex]
The total value of the liquid in the container is about $41,866,666.67.

Elena would like to know the average height of seventh graders in her school district. She measures the heights of everyone in a random sample of 20 students. The mean height of Elena's sample is 58 inches, and the MAD (mean absolute deviation) is 3 inches. Select all the true statements. The mean height of all seventh graders is likely be between 52 and 64 inches. Another random sample of 20 students will always have a mean of 58 inches. A sample of 20 female students would be more likely to get an accurate estimate of the mean height of the population than a sample of a mix of 20 male and female students. m A sample of 100 seventh graders would be more likely to get an accurate estimate of the mean height of the population than a sample of 20 seventh graders. a Elena's sample proves that half of all seventh graders are taller than 58 inches.
Answer:
A. The median height of the sample must be between 59 and 63 inches.
B. Another random sample of 20 students is likely to have a mean between 57 and 65 inches.
E. Elena would be more likely to get an accurate estimate of the mean height of the population by sampling 40 people instead of sampling 20 people.
Step-by-step explanation:
The mean absolute deviation shows the variation in a given data set. It can be determined by calculating the mean of the absolute value of the initial mean and each data set. It describes how spread out the data set are.
With respect to Elena's sampling, the mean absolute deviation is 2. This shows that there is little variation among the data set.
The estimate becomes more accurate if she increase the sample size. Thus options A, B and E are appropriate.
