Answer:
Weight from height ;
409 ;
790 ;
55,505
Yes
Step-by-step explanation:
Height, X :
ΣX = (60+62+63+66.5+73.5+84) = 409
Weight, Y :
ΣY = (99 + 107 + 111 + 125 + 153 + 195) = 790
Height * weight = ΣXY
(60*99 +62*107 +63*111 +66.5*125 +73.5*153 +84*195) = 55,505
To know If to take the bet, we calculate the strength of the relationship :
Correlation Coefficient :
Using calculator :
The correlation Coefficient = 1 ; meaning that there is a perfect relationship between height and weight. Hence, take the bet.
Answer:
6
Step by step explanation:
2 + 2 * x = 10
2x+2=10
2x+2−2=10−2
Therefore, x = 6
Answer: The width is 12 feet.
Step-by-step explanation:
2w + 2l = perimeter
52 = 2w + 2(14)
2 * 14 = 28
28 + 2w = 52
-28
2w = 24
/2
w = 12
