Answer:You have roughly the same chance of being called as anyone else living in the United States who has a telephone. This chance, however, is only about 1 in 154,000 for a typical Pew Research Center survey. To obtain that rough estimate, we divide the current adult population of the U.S. (about 235 million) by the typical sample size of our polls (usually around 1,500 people). Telephone numbers for Pew Research Center polls are generated through a process that attempts to give every household in the population a known chance of being included. Of course, if you don’t have a telephone at all (about 2% of households), then you have no chance of being included in our telephone surveys.

Sam and you are going to paint your room together.
Sam takes 10 minutes to paint 25 square feet.
It takes you 5 minutes to paint 25 square feet.
Sam says, "If we paint together, then it will take 15 minutes for us to cover
feet."
TI
of
Give an explanation to convince Sam that she is incorrect.
.
Answer:
Sam is incorrect because you would not add the two times together. Hence there being 2 people working it would take you guys less time. You would actually subtract the times to get 5 minutes
Step-by-step explanation:
Answer:
Sam 's thinking is incorrect.
Step-by-step explanation:
Because If Sam takes 10 minutes to paint 25 square feet, then 5 minutes will be paint 12.5 sf... So if 15 minutes will paint 37.5 square feet. (by Sam)
---For me: if 5 mutes to paint 25 square feet.--->10 minutes will be 50 sf---> then 15 minutes will paint 75 square feet...
So If Same and I paint together will be 12.5 + 75 = 112.5 square feet
---Not 50 square feet...
What Sam says is incorrect....He can't add times together., that' s wrong.

Which of the following is a ray as shown in the drawing?
6 is 30% of _________ .
Answer:20
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
Let N be the number
"Is" in this case is =
"Of" means "multiply"
So we got
6 = .3N divide both sides by .3
6/.3 = 20
N=20
A large pizza has a radius of 7 in. The pizza is cut into 8 slices of equal size. What is the area of 1 slice, rounded to the nearest whole number? Use 3.14 for π.
Answer:
The area of 1 slice is of 19 square inches.
Step-by-step explanation:
Area of a circle:
The area of a circle of radius r is given by:
[tex]A = \pi r^2[/tex]
A large pizza has a radius of 7 in.
So its area of the pizza, in square inches, is of:
[tex]A = \pi(7)^2 = 49\pi = 49*3.14 = 153.86[/tex]
The pizza is cut into 8 slices of equal size. What is the area of 1 slice, rounded to the nearest whole number?
Area of the pizza divided by 8. So
153.86/8 = 19.2
Rounding to the nearest whole number, the area of 1 slice is of 19 square inches.
Without using a calculator, match each expression to the correct point.
Answer:
The locations of each irrational number are the following:
[tex]\sqrt{16}[/tex] - Point [tex]a[/tex]
[tex]\sqrt{27}[/tex] - Point [tex]b[/tex]
[tex]\sqrt{32}[/tex] - Point [tex]c[/tex]
Step-by-step explanation:
[tex]\sqrt{16}[/tex] is an irrational number that is also rational, since [tex]4^{2} = 16[/tex]. Then, [tex]\sqrt{16}[/tex] must be point [tex]a[/tex].
Both [tex]\sqrt{27}[/tex] and [tex]\sqrt{32}[/tex] are greater than [tex]\sqrt{25} = 5[/tex] and less than [tex]\sqrt{36} = 6[/tex]. Then, both are between 5 and 6. Since [tex]\sqrt{27} < \sqrt{32}[/tex], [tex]\sqrt{27}[/tex] must be point [tex]b[/tex] and [tex]\sqrt{32}[/tex] must be point [tex]c[/tex].
Kiran is recalling Easter egg hunts from her childhood. She remembers that there were 2 Easter egg hunts where
she found 8 eggs each and 4 Easter egg hunts where she found 11leggs each. She also knows that she averaged
11.6 eggs per Easter egg hunt. This information is summarized in the table below.
Fill in the missing blank with the number of hunts where Kiran found 14 eggs.
Answer:
In 4 Easter egg hunts she found 14 eggs
Step-by-step explanation:
The table is missing, but the thing we need to complete in the table is a number X, where X is the number of easter egg hunts where she found 14 eggs.
We already know that:
2 times she found 8 eggs
4 times she found 11 eggs
X times she found 14 eggs.
And we also know that the average is 11.6 eggs.
Where the average can be computed as:
The quotient between all the eggs she found in all the Easter egg hunts, and the total number of Easter egg hunts were she attended.
She got a total of: 2*8 eggs + 4*11 eggs + X*14 eggs.
And she attended a total of 2 + 4 + X Easter egg hunts, then:
This is then:
[tex]avg = \frac{2*8 + 4*11 + X*14}{2 + 4 + X} = 11.6[/tex]
Now we just need to solve the above equation for X.
We can rewrite this as:
[tex]2*8 + 4*11 + X*14 = 11.6*(2 + 4 + X)[/tex]
[tex]16 + 44 + X*14 = 11.6*(6 + X)[/tex]
[tex]60 + X*14 = 11.6*(6 + X) = 11.6*X + 69.6[/tex]
[tex](14 - 11.6)*X = 69.6 - 60[/tex]
[tex]2.4*X = 9.6[/tex]
X = 9.6/2.4 = 4
This means that in 4 Easter egg hunts she found 14 eggs.

Factor Зу2 - 4у.
y(4 - Зу)
y(Зу - 4)
y(4y-3)
Find the properties of each Quadratic Function
Answer:
1.) up
2.) (-2,-5)
3.) x = -2
4.) (-2,-5)
5.) y = -5
6.) -∞ < x < ∞
7.) -5 < y < ∞
8.) (0,0)
9.) (0,0) and (-4,0)
10.) two solutions
Step-by-step explanation:
1.) because the parabola opens upward and the vertex is down
2.) the lowest point of the parabola is (-2,-5)
3.) If a line was drawn through the point x = -2, the two halves of the parabola would look symmetrical ( the same on both sides).
4.) The minimum point on the graph is ( -2,-5), because that is the lowest point on this upward parabola, and we can not determine the maximum.
5.) The minimum value of y is y = -5, because that is the lowest value of y on this graph, and we can not determine the maximum.
6.) Because the arms of the parabola continue traveling through negative infinity and positive infinity on the x-axis, the domain is -∞ < x < ∞.
7.) The arms of the parabola go from y = -5 to infinity, so the range of the parabola is -5 < y < ∞.
8.) The parabola first crosses the y-axis at the point (0,0)
9.) The parabola first crosses the x-axis at the points (0,0) and (-4,0)
10,) The solution to the parabola is the variable x. The solutions (x intercepts) of the parabola are x = 0 and x = -4.

A coffee machine dispenses normally distributed amounts of coffee with a mean of 12 ounces and a standard deviation of 0.2 ounces. If a sample of 9 cups is selected, find the probability that the mean of the sample will be less than 12.1 ounces.
Answer:
0.9332 = 93.32% probability that the mean of the sample will be less than 12.1 ounces.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
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 z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
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].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of 12 ounces and a standard deviation of 0.2 ounces.
This means that [tex]\mu = 12, \sigma = 0.2[/tex]
Sample of 9:
This means that [tex]n = 9, s = \frac{0.2}{\sqrt{9}}[/tex]
Find the probability that the mean of the sample will be less than 12.1 ounces.
This is the pvalue of Z when X = 12.1. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{12.1 - 12}{\frac{0.2}{\sqrt{9}}}[/tex]
[tex]Z = 1.5[/tex]
[tex]Z = 1.5[/tex] has a pvalue of 0.9332
0.9332 = 93.32% probability that the mean of the sample will be less than 12.1 ounces.
The average weight of a female hippopotamus is 1½ tons. How many pounds is this?
Answer:
3000 pounds
Step-by-step explanation:
Since there are 2000 pounds in a ton, find how many pounds there are by multiplying 1.5 by 2000
1.5(2000)
= 3000
So, this is 3000 pounds

Michael is debating the two job offers below. Determine which will result in a higher income.
OFFER A
$34,500 ANNUALLY
OFFER B
$2,885 MONTHLY
B
Step-by-step explanation:
In a year, offer B would be more. Since annually is once a year and there are 12 months in a year, multiplying B by 12 would get each to a year.
