Answer:
c. 64% of the variation in the weight of luggage is explained by the number of passengers
Step-by-step explanation:
The explained variance is a measure given by the coefficient of determination, R².
The value Given above is the correlation Coefficient, R, which is 0.8
The Coefficient of determination, R² = 0.8² = 0.64, expressing as a percentage ; 0.64 * 100% = 64%
This means that 64% of the variation in the dependent variable is can be explained by the regression line. (independent variable)
Answer:15 per person
Step-by-step explanation:
if you divide 60 divided by 4 (mom,dad,sister,and aunt) you would have to pay them all 15 each
Answer:

Step-by-step explanation:
2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24
4 , 8 , 12, 16, 20, 24
6, 12, 18, 24
8, 16, 24
Looking at the multiples of these numbers, we choose the multiple they all have in common. I usually do this for the two biggest numbers, (8 and 6;) and check my work with the others.

Answer:
492,800
Step-by-step explanation:
Given ith term of an arithmetic sequence as shown:
ai = a(i-1)+2
and a1 = 5
When i = 2
a2 = a(2-1)+2
a2 = a1+2
a2 = 5+2
a2 = 7
When i = 3
a3 = a(3-1)+2
a3 = a2+2
a3 = 7+2
a3 = 9
It can be seen that a1, a2 and a3 forms an arithmetic progression
5,7,9...
Given first term a1 = 5
Common difference d = 7-5= 9-7 = 2
To calculate the sum of the first 700 of the sequence, we will use the formula for finding the sum of an arithmetic sequence.
Sn = n/2{2a1+(n-1)d}
Given n = 700
S700 = 700/2{2(5)+(700-1)2}
S700 = 350{10+699(2)}
S700 = 350{10+1398}
S700 = 350×1408
S700 = 492,800
Therefore, the sum of the first 700 terms in the sequence is 492,800
