If two parallel lines are cut by a transversal,
then alternate interior angles are congruent.
Since one alternate interior angle measures 60 degrees,
the other alternate interior angle must also measure 60 degrees.
X + (x+2) = 154
combine like terms
2x + 2 = 154
subtract 2
2x = 154
divide by 2
x = 76
so the two numbers are 76 and 78
Well the answer would be
6x2 ( 2 is an exponent) -7
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.
