Eric's father works two part time jobs, one in the morning and one in the afternoon, and works a total of 40 hours each 5-day workweek. If his schedule is the same each day, and he works 3 hours each morning, how many hours does Eric's father work each afternoon?

Answers

Answer 1
Answer:

Answer:

Eric's father works for 5 hours in the afternoon

Step-by-step explanation:

Eric's father works two part time jobs, one in the morning and one in the afternoon, and works a total of 40 hours each 5-day workweek.

Step 1

The number of hours he works each days is calculated as:

40 hours÷ 5days

= 8 hours per day.

Hence, he works 8 hours per day.

Step 2

We are told in the question that:

If his schedule is the same each day, and he works 3 hours each morning, how many hours does Eric's father work each afternoon?

The total number of hours in works in a day = Number of hours worked in the morning + Number of hours worked in the afternoon

Hence:

8 hours = 3 hours + x

x = 8 hours - 3 hours

x = 5 hours

Therefore, Eric's father works for 5 hours in the afternoon

Lu is making a quilt that is 20 squares wide and has 24 rows. The border of the quilt is made by using each design equally as often. Each square can hold one design. How many of each design does she use for the border?

Answers

Here is the correct answer for this question

The quilt has 4 sides.
The border will have 20 squares two times, and 24 squares two times as well, that is the perimeter or the border.
= 20*2 + 24*2
= 40 + 48
= 88

So, from the answer above, the border will have 88 squares total.
Lu can use any toy design 88 times.

Two minutes after a diver enters the water, he has descended 52 feet After 5 minutes, he has descended 130 feet At what rate is the scuba diver descending

Answers

Answer:

26ft/minute

Step-by-step explanation:

The question asks to calculate the rate at with a scuba diver is descending.

Firstly, we should know that the rate at which the scuba diver is descending is calculated as the total amount of distance descended, divided by the total amount of time taken.

The total amount of distance descended is 52ft + 130ft = 182ft

The total amount of time taken is 5 + 2= 7 minutes

The rate of descending is thus 182ft/7min = 26ft/minute

Answer:

-(8)/(7)

Step-by-step explanation:

-9x+4y=8

-3x-y=4

Multiple the entire second equation by 4

-12x-4y=16

-9x+4y=8

__________

-21x=24

divide each side by -21 and simplify

x= -(8)/(7)

Answer C

Which phrase accurately describes a distribution that's bell-shaped but not symmetric?

Answers

A skewed distribution should be the right answer. It is a distribution that's bell-shaped but not symmetric. A skewed distribution do not have a symmetric appearance unlike a normal distribution. Skewness is the measure of the asymmetry.

Answer:

The answer is skewed distribution.

Step-by-step explanation:

Which phrase accurately describes a distribution that's bell-shaped but not symmetric?

Skewness is defined as asymmetry in a statistical distribution where the curve appears distorted or skewed either to the left or to the right, but not in the center.

When distributions possess a bell shape but is not centered, then they are called skewed distributions.

You roll a six-sided number cube. Which events are mutually exclusive? A) rolling a multiple of 2 and a multiple of 4
B) rolling a multiple of 3 and a multiple of 6
C) rolling an even number and an odd number
D) rolling a prime number and an even number

Answers

mutually exclusive is the events which couldn't happen at the same time, so I suggest you to go with this: C) rolling an even number and an odd number

Answer: C) rolling an even number and an odd number

Step-by-step explanation:

For any event A and B , we say they are mutually exclusive if they are disjoint such that there have no elements in common.

Let's check all the options:

A) rolling a multiple of 2 and a multiple of 4

Multiple of 2 on dice = 2,4,6

Multiple of 4 on dice = 4

They are not disjoint since 4 is the common element.

B) rolling a multiple of 3 and a multiple of 6

Multiple of 3 on dice = 3,6

Multiple of 6 on dice = 6

They are not disjoint since 6 is the common element.

C) rolling an even number and an odd number

Even number on dice = 2,4,6

Odd number on dice = 1,3,5

∴ They are disjoint event as they have no common element.

D) rolling a prime number and an even number.

Prime number on dice = 2,3,5

They are not disjoint since 2 is the common element.
