Answer:

[tex]6^{2}[/tex]

Step-by-step explanation:

When dividing numbers with same bases with indices this is the rule:

[tex]\frac{x^{y}}{x^{z} } =x^{y-z}[/tex]

So the answer is:

[tex]6^{7-5} = 6^{2}[/tex]

Answer:

True

Step-by-step explanation:

2x + 14y - y  = 2x + 13y

Have a good day :)

Answer:

true

Step-by-step explanation:

Distribute the 2 to the x and 7y. your equation will nob be 2x+14y-y=2x+13. so combine the like terms, 14y and -y, so you get 13y. you now have 2x+13y=2x+13y. which is true

90% of all samples have a confidence interval that contains the right average travel time for all employed adults in California.

Increased Sample Size: This provides more information about the population and allows us to calculate an accurate estimate. Data collection is expensive and time-consuming.

Decrease in Confidence Level: Confidence interval having correct population interval is less confident. It has fewer possible values for true population parameters. Hence, it is less confident about the confidence interval has the correct population parameters.

Non-Response Bias

Nonresponse bias happens when there isn't enough data for everyone in the sample. People whose data is unavailable lead to bias and over- or underestimate the true population. The margin of error is not used because it merely takes potential variation into consideration.

Answer:

B and C

Step-by-step explanation:

A general way to know this is, if the answer can be given as a rate, percentage, or probability, then this is a statistical question

If the answer is yes, no, true, false, or something exact, then the question is not statistical.

Let's analyze the given questions:

a) "How many cups are in a gallon?"

There is an exact number of cups in a gallon (16) so this is not an staistical question.

b) "Which measure spoon do home backers use most frequently?"

While here the answer may be something like "teaspoon", the root of the answer is a percentage, here we actually would see the percent of home backers (so we need to find a sample, study that sample, etc) that use each spoon, and based on that, we could conclude what is the correct answer, then this is a statistical question.

c) "On average, how much salt do professional pastry chefs use in pie crust?"

Here we need to find a mean value, so we would need to do a survey and etc, then this is a statistical question.

d) "Which is larger, 17 ounces or 2 cups?"

Here we have an exact solution, so this is not a statistical question.

e) "Did a specific store sell more measuring cups or measuring spoons on a given day?"

Here we just need to compare the two numbers:

number of measuring cups sold = k

number of measuring spoons sold = m

And we need to see which one is larger, so the answer is exact, thus, this is not a statistical question.

This may be similar to option B, the difference is that in option B we are talking about all home backers, so we need to find a sample and do statistics, while in this case, we are talking about a specific store.

Then the correct options are: B and C

Answer:

8¹

Step-by-step explanation:

The given expression is :

8 to the power 1.

We need to write it in exponential form.

If we write 10³, here 10 is base and 3 is exponent.

8 to the power 1 = 8¹

The base is 8 and exponent is 1.

Hence, the exponential form is 8¹.

Vertex (2, 3)

Axis of Symmetry: x = 2

Step-by-step explanation:

You can look at the labeling from my last answer, the parabola is just upside down but it is still the same label.

Hope it makes sense :)

Answer:

Axis of Symmetry:  x = 2

Vertex:  (2, 3)

Step-by-step explanation:

find axis of symmetry:  x = -b/2a

x = -8 ÷ 2(-2)

x = 2

find vertex by substituting 2 for 'x':

y = -2(2²) + 8(2) - 5

y = -8 + 16 - 5

y = 8 - 5

y = 3

Vertex:  (2, 3)

Answer:

50.24

Step-by-step explanation:

The formula for solving circumference is 2 x pi x r

first the radius is 8 (divide 16 by 2 and get radius)

( pi can be 22/7 or 3.14. but I’m taking 3.14 )

second, we have all values, now we just have to substitute them!

Pi = 3.14

R = 8

so when we do 2x 3.14 x 8 = 50.24

Answer:

The mean of X is 164.5 and the standard deviation is 9.34.

Step-by-step explanation:

For each adult, there are only two possible outcomes. Either they believe that the overall state of moral values is poor, or they do not. The probability of an adult believing this is independent of any other adult, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

Suppose that a recent poll found that 47​% of adults believe that the overall state of moral values is poor.

This means that [tex]p = 0.47[/tex]

350 randomly selected​ adults

This means that [tex]n = 350[/tex]

What is the mean of X and the standard deviation of X?

Mean:

[tex]E(X) = np = 350*0.47 = 164.5[/tex]

Standard deviation:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{350*0.47*0.53} = 9.34[/tex]

The mean of X is 164.5 and the standard deviation is 9.34.
