Answer:
there cannot be any solution of the given linear equation.
Step-by-step explanation:
i) the linear equation of 18x + = 6(3x + 25)
ii) transforming the equation to a simpler form we get
18x + = 18x + 150 which implies that = 150 which is not true.
iii) therefore there cannot be any solution of the given linear equation.
The answer would be 5/27
(If you want me to explain I can)
Hope this helps
Have a great day/night
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.
80 ok because it has that
