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
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:
-
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= -
x - 3y + 7 = 0
x - 3y - 7 = 0
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.
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
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.
