Answer: 30%
Step-by-step explanation: 21/70 = 21 divide 70 = 0.3 = 30%
Answer:
a = 6
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 8^2 = 10 ^2
a^2 +64 = 100
a^2 = 100 -64
a^2 = 36
Take the square root of each side
sqrt(a^2) = sqrt(36)
a = 6
Answer:
x = 7/10
Step-by-step explanation:
9/5 x -2/5 = (8x+3)/10
get a common denominator of 10
9/5 x * 2/2 - 2/5 * 2/2 = (8x+3)/10
18 /10 x - 4/10 = (8x+3)/10
multiply by 10 on each side to clear the fractions
10 *(18 /10 x - 4/10) = 10*(8x+3)/10
distribute
10 *(18 /10 x) -10* 4/10) = 10*(8x+3)/10
18x - 4 = 8x+3
subtract 8x from each side
18x-8x -4 = 8x+3 -8x
10x-4 = 3
add 4 to each side
10x-4+4 = 3+4
10x = 7
divide by 10
10x/10 = 7/10
x = 7/10
Answer: H0 : β1 = β2 = β3 = β4 = 0
Step-by-step explanation:
The null hypothesis refers to a hypotheses that simply states that no relationship exists between two phenomenons that are being tested.
In testing the validity of a multiple regression model in which there are four independent variables, the null hypothesis is H0 : β1 = β2 = β3 = β4 = 0.
