The addition of the row and column shows that the number of people polled will be 166.
<h3>How to calculate the number?</h3>
From the information given, the guest thing to do is to add the column. This will be:
= 48 + 118 = 166
Also, it's important to add the row. This will be:
= 69 + 97 = 166
Therefore, the number of people polled will be 166.

Answer:
628
Step-by-step explanation:
using formula 1/3 x pi x r x r x h
1/3 x 3.14 x 10 x 10 x 6 = 628
1 electron has a mass of 9.1 X 10-31 kg. How many electrons n does it take to make 1 kg?
(1 e)/(9.1 X 10-31 kg) = n/(1 kg)
So, n = 1.10 X 1030 electrons
Each electron has a charge of 1.6 X 10-19 C, where C stands for Coulombs. So, the n electrons have a charge of q = ne = (1.10 X 1030 electrons) X (1.6 X 10-19 C/electron) = 1.76 X 1011 C.
Answer:
(-3, 4).
Step-by-step explanation:
When f(x) becomes f(x + 1), all that is happening is that the y-value increases by 1.
So, (-3, 3) becomes (-3, 3 + 1). That is (-3, 4).
Hope this helps!
