Select the correct answer. Martin runs 100 meters in 15 seconds. What is the equation for d, the distance in meters that Martin covers per second? O A. 15+ d = 100 B. 100 + d = 15 O c. dx 15 = 100 D. d x 100 = 15

Answers

Answer 1

Answer:

Answer:

C) d*15=100

Step-by-step explanation:

The word problem already gives us the product or the end result “Martin runs 100 meters in 15 seconds. So the 100 has to be equal to the expression.

=100

“Per second” this suggests that we should multiply

the most logical answer is d*15=100 or dx15=100

a. ii. and iv.

b. ii.

Step-by-step explanation:

Hello!

The research study involves elderly persons it was divided into two considering those who suffered depression and those that didn't suffer depression, then the proportion of persons that suffered dementia was counted.

a. Choose the relevant population and the sample.

i. The sample consists of all elderly people.

ii. The sample consists of 949 elderly people.

iii. The population is all younger and elderly people.

iv. The population is all elderly people.

Note: When you determine a population from a text, you NEVER mention a number, even if the population is finite and the total of individuals in it is known. When you determine a sample it always comes with its size.

b. Do the numbers 22% and 17% represent the population parameters or the sample statistics?

i. Population parameters

ii.Sample Statistics

The proportions were determined after taking the sample, as said in the text, first the sample was taken, then the researchers determined from this sample wich elders suffered from depression and which didn't suffer from depression and these two groups, the number of people with dementia was determined. Meaning these are sample values, not population parameters.

I hope it helps!

2Illustrate the following numbers using base 10 blocks:
a) 841
b) 106
c) 3 051

Answers

Final answer:

To illustrate numbers using base 10 blocks, you need to understand the place values and represent each digit using the appropriate base 10 block.

Explanation:

To illustrate numbers using base 10 blocks, we need to understand that each number is made up of different place values—ones, tens, hundreds, and so on. A base 10 block for the number 841 would consist of 8 hundreds blocks, 4 tens blocks, and 1 ones block. For the number 106, we would have 1 hundreds block, 0 tens blocks, and 6 ones blocks. Lastly, for the number 3,051, we would have 3 thousands blocks, 0 hundreds blocks, 5 tens blocks, and 1 ones block.

Tom is the deli manager at a grocery store.He needs to schedule employees to staff the deli department at least 260 person-hours per week.Tom has one part-time employee who works 20 hours per week.Each full-time employee works 40 hours per week.Write an inequality to determine f, the number of full time employees Tom must schedule, so that his employees will work at least 260 person-hours per week. Solve and graph. !PLEASE HELP!

Answers

I hope this is right but:
Let n=number of full time employees

260<=20+n*40
260-20<=N*40
240<=n*40
n>=240/40
n>=6 full time employees

which means he would have to hire at least 6 or more fully time employees

Though I'm not sure if the attached file is the graph you are looking for
