Answer:
Letter c
Step-by-step explanation:
You are distributing the 7 to each term in the parentheses.
7(8x) is 56 x
Here is the tricky part. You can think of it a couple of ways:
7(-4y) = -28y a positive times a negative is a negative.
or 7(4y) = 28 , but then remember that you are subtracting so it will become -28
7(6) = 56
56x - 28y +42
Answer:
560 dinners
Step-by-step explanation:
First, find the amount of ounces by multiplying 350 pounds by 16 since every one pound is 16 ounces. 350×16=5600. That means there are 5600 ounces of meat. Therefore, to find the amount of steaks that can be served, divide 5600 divided by 10. 5600÷10=560.
Answer: 90% confidence interval would be (0.448, 0.552).
Step-by-step explanation:
Since we have given that
x = 125
n = 250
So, 
We need to find the 90% confidence interval.
so, z = 1.64
So, interval would be
Hence, 90% confidence interval would be (0.448, 0.552)
Fraction of tank drops in every 10 minutes = 1/3 inches.
We need to find the expected change in the tank's water level after 2.25 hours.
Let us convert 2.25 hours in minutes.
1 hours = 60 minutes.
2.25 hours = 2.25 × 60 = 135 minutes.
<em>We need to divide 135 by 10.</em>
We get 13.5.
Now, we need to <em>multiply 1/3 by 13.5</em>, we get.
13.5/3 = 4.5 inches.
<h3>So, tank would drop 4.5 inches after 2.25 hours.</h3>
