Answer:
g = j - 12
Step-by-step explanation:
Let's say Jessie installed j axles. Convert words to math:
- "12 more" = + 12
- "the number of engine blocks her friend Gus installed yesterday" = g
Put it together: g + 12. This is equal to j: j = g + 12. Solve for g:
j = g + 12
g = j - 12
Answer:
B
Step-by-step explanation:
Given
(4x² - 3x - 4) - (3x² + 4x - 8) ← distribute by - 1
= 4x² - 3x - 4 - 3x² - 4x + 8 ← collect like terms
= x² - 7x + 4 → B
Answer:
P = 50 ft
Step-by-step explanation:
A = L*W
If
L = 4W
then
100 = 4W*W
100 = 4W^2
W^2 = 100/4
W^2 = 25
W = 5 ft
Then
L= 4(5)
L= 20 ft
P = 2L + 2W
Then
P = 2(20) + 2(5)
P = 40 + 10
P = 50 ft

Answer:
Best predicted value of y' = 86.16 kg
Step-by-step explanation:
Given,
n = 100
Range of heights = 138 - 190cm
Range of weight = 39 to 150 kg
x' =167.46 cm
y' = 81.44 kg
r = 0.108
p value = 0.285
y = - 105 + 1.08x
Significance level = 0.05
We reject H0 since pvalue, 0.285 is less than significance level of 0.05.
Therefore,
Given height of adult male, x = 177 cm
y = - 105 + 1.08x
The best predicted value of y' =
y' = - 105 + 1.08(177)
y' = 86.16 kg
The best predicted value of y' is 86.16kg
They are both correct becuase lets say it was a shirt that was $30 and it was 30% off. For Jasani it would be 30 * 0.7 which equals $9 then you would subtract this 30 - 9 = 21. For Hanna it would be 30 - 0.3(30) which equals $21. So in the end they are both correct!
