16 people would be at the dinner because Jim and Sarah invited 7 friends and each friend brought 1 guest, so you do 7*2=14 and the 14 + Jim and Sarah=16 people.
The equation would be y = -5x - 7
Answer:
<h2>There is a 25% chances of receiving a yellow golf ball next time.</h2>
Step-by-step explanation:
Givens
- There are 8 golf balls in total.
- There are 2 yellow golf balls out of 8.
The experimental probability refers to the ratio between the number of times an even happens and the total number of cases. So,
Therefore, there is a 25% chances of receiving a yellow golf ball next time.
-6 and -4 are your inputs -2 and 7 are your outputs
The formula for an area of a regular parallelogram is:
A = l * w
Where,
l = length
w = width
We are given that the total measurement of fence is only
60 feet and one side of the house is used as one side of the pen. Therefore,
l + 2 w = 60
<span>or simplifying to make an explicit expression for
one variable, say l:</span>
l = 60 – 2 w
<span>Substituting to the 1st equation:</span>
A = (60 – 2 w) * w
A = 60 w – 2 w^2
<span>The maxima are obtained by getting the 1st
derivative then equating dA/dw = 0:</span>
dA/dw
= 60 – 4 w
60 –
4 w = 0
4 w
= 60
w =
15
Since
l = 60 - 2w
l =
60 – 30
l =
30
<span>Therefore
the dimension that will make the largest pen is 15 ft by 30 ft.</span>
<span>ANSWER: C</span>
