Answer:
a) 3 people will need 35 days to paint the bridge
b) p=105/t
Step-by-step explanation:
a)
We have 7 people each one is to work 15 days, so the bridge needs a total of 7(15) days of work
7(15)=105
Then we have 3 people each one is to work t days, altogether should do a total of 105 days of work
3(t)=105
Solve for t
t=35
b)
Substitute p for 3 in the second equation
p(t)=105
Solve for p
p=105/t
Jorrel is wrong. 18 shots made out of the 40 shots attempted is 45%. 18 divided by 40 is 45% while 16 shots of him making it would have been a 40% of the shots out of 40 he took.
Answer:
Find every possible factors of 32, and pair them
Step-by-step explanation:
if the same value for width/length cant be repeated, 3 total possible values is possible
1 × 32 = 32
2 × 16 = 32
4 × 8 = 32
if the value of width/length can be repeated, 6 total different values.
1 × 32 = 32
2 × 16 = 32
4 × 8 = 32
32 × 1 = 32
16 × 2= 32
8 × 4= 32
you can easily find all factors using online factor calculator

Check explanation section.
Step-by-step explanation:
So, we have the following parameters or information from the question above:
=> that the regression equation is Score = 31.55 + 10.90 Years.
So, the regression equation is in the form of mx + c.
Thus, the coefficient that is constant = 31.55 and the coefficient that shows or represents the years = 10.90.
=> Also, we have the value which is most important in this question that is the coefficient of Determination which is represented as R-sq and has the value of 83%.
The percentage of the total variation in test scores is NOT explained by the linear relationship between years of study and test scores = 100% - 83% = 17%.
For the percentage of the total variation in test scores is explained by the linear relationship between years of study and test scores = R- sq = 83%.
Let U be plums, A be apples and P be pears.
13U = 2A + P
4U + A = P
Substituting P from the second equation to the first:
13U = 2A + 4U + A
9U = 3A
A = 3U
Now, substituting the value of A into the second equation:
4U + 3U = P
7U = P
7 plums weigh the same as one pear.
