Answer:
18,20,22
Step-by-step explanation:
18,20,22 are consecutive even numbers that sum to equal 60.
First, you should calculate the square footage of the fence.6ft∗300ft=1800ft2 Then to find the number of gallons of paint needed, divide the area of the fence by the area covered with each gallon of paint: 1800ft2÷400ft2=4.5 So, 4.5 gallons of paint, or rounding up, 5.
Answer:histogram 4
Is this for stats? each number is going by 5 and looking at the numbers you can easily eliminate 2 and 3 as there is nothing in the area of 50-60 that only leaves 1 and 4 look at the numbers and how they add up in the frequency from 70-75 there are two numbers that meet the criteria. Histogram 1 only shows one number for that section so i assume that it should be number 4.
Answer:
6 terms
Step-by-step explanation:
2 − 2/4 + 2/9 − 2/16 + ...
∑ (-1)ⁿ⁺¹ 2 / n²
Applying alternating series test:
lim(n→∞) 2/n² = 0
2/(n+1)² < 2/n², so the series is decreasing.
Therefore, the series converges.
2/(n+1)² < 0.05
(n+1)²/2 > 20
(n+1)² > 40
n+1 > 6.32
n > 5.32
n = 6
