Answer:

Step-by-step explanation:

The null hypothesis is the statement or claim that is believed or assumed to be true. In this case, the null hypothesis is "They believe that 40% of first-time borrowers take out smaller loans than other borrowers". Since we are dealing with proportion, we will denote it with p. The null hypothesis would be

p = 0.4

The alternative hypothesis is what the researcher expects or predicts. It is the statement that is believed to be true if the null hypothesis is rejected. The alternative hypothesis is "They perform a hypothesis test to determine if the percentage is the same or different from 40%". It would be written as

p ≠ 0.4

Let X be the set of all 3×3 matrices whose diagonal entries are all 0. With the usual matrix addition and scalar multiplication, is X a vector space? (b) Let Y be the set of all 3 × 3 matrices whose diagonal entries add up to 0. With the usual matrix addition and scalar multiplication, is Y a vector space?

Choose the true statement.0-2<-3O-2» -3O -2 = -3

Which expression shows the ASSOCIATIVE PROPERTY? 3 + a + b = a + 3 + b 3(ab) = (3a)b (3 + a) + b = 3 + (a + b) 3 - a = 3 - b

Is this right? please correct me if I'm wrong.

**Answer:**

**y = -1.**

**Step-by-step explanation:**

The value of y is -1 as it passes through the y axis. The values of x on the line are infinite.

This line's equation is y = -1.

-1 would be your answer.

Natalie went to the hardware store to buy a water filter and a deadbolt, and

while she was in the checkout line, she also threw some caulk and some

super glue into her shopping cart. Which two products were impulse

purchases?

A. The water filter and the super glue

B. The caulk and super glue

C. The caulk and the deadbolt

D. The water filter and the deadbolt

**Answer:**

B. The caulk and super glue

**Step-by-step explanation:**

An impulse purchase is when you decide to buy something you didn't plan to in the spur of the moment. For example, when you are shopping your groceries and you decide to buy a product you see and that you don't have in your list. According to this, the two products that were impulse purchases are caulk and super glue because Natalie didn't plan to buy these products and she decided to do it when she was in the checkout line to pay for the other products that she planned to buy.

**Answer:**

B.

**Step-by-step explanation:**

took the test

Answer: 16 cans

Step-by-step explanation:

51x32=1632sqft

1632/102=16 cans of wood stain

16 cans ,51x32=1632 square feet, divide that and it’s 16 cans

Whole formula 2*pi*radius^2 + 2*pi*radius*height:

157+942= 1099

SA= 1099

157+942= 1099

SA= 1099

56 degrees

84 degrees

96 degrees

124 degrees

the answer his 24 degrees

False

True

__A statistic is a characteristic of a sample, a portion of the target population. A parameter is a fixed, unknown numerical value, while the statistic is a known number and a variable which depends on the portion of the population.__

**Parameter Definition:** a quantity or statistical measure that, for a given population, is fixed and that is used as the value of a variable in some general distribution or frequency function to make it descriptive of that.

**Population:** The mean and variance of a population are population parameters.

**Statistic Definiton:** A statistic or sample statistic is any quantity computed from values in a sample that is used for a statistical purpose. Statistical purposes include estimating a population parameter, describing a sample, or evaluating a hypothesis. The average of sample values is a statistic.

The answer is: true
