Answer:
12 meters
Step-by-step explanation:
The area of a parallelogram can be found using:
a=bh
We know that the base is 7 meters, and the area is 84 square meters. Therefore, we can substitute 7 in for b, and 84 in for a.
84=7h
We want to find the height. To do this, we have to get h by itself. Since h is being multiplied by 7, divide both sides by 7.
84/7=7h/7
12=h
So, the height is 12 meters
Answer:
Correct option: A. Weight.
Step-by-step explanation:
In regression analysis there are two kinds of variables: Explanatory and Response variable.
The explanatory variable are used to predict the changes in the response variable. They are also known as independent or predictor variable.
The response variable are observed for any changes caused by the explanatory variable. They are also known as the dependent or experimental variable.
In this case it is provided that heavier cars have lower fuel efficiencies.
It implies that there is linear inverse relationship between the variables weight of the car and fuel efficiency.
The response variable is the fuel efficiency and the explanatory variable is the weight of the car. Since the weight of the car is used to determine the fuel efficiency.
Thus, the explanatory variable is the weight of the car.
Answer:
Step-by-step explanation:
function Fn = Fnorm(A)
[r,c] = size(A);
sum = 0;
for i=1:r
for j=1:c
sum = sum + (A(i,j) * A(i,j));
end
end
Fn = sqrt(sum);
end
A = [5 7 9; 1 8 4; 7 6 2]
fprintf("The Frobenius norm of an m × n matrix is\n");
Fn = Fnorm(A)
=========================================================================================\
X is the number
sum means add
sum of half a number and 4 means
(x/2)+4
result is -16
(x/2)+4=-16
minus 4 both sides
x/2=-20
times 2 both sides
x=-40
the number is -40
