To divide fractions, you flip the second one and multiply them so it would be:
(-3/8) / (7/12)
-3/8 * 12/7
-36/56
This can be simplified to :
-9/14
Because you divide both the numerator and denominator by 4.
Hope this helps :)
Answer:

Answer:
6x - 8 = 16
Step-by-step explanation:
Solve the equation for x
5(3x - 7) = 25 ( divide both sides by 5 )
3x - 7 = 5 ( add 7 to both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Thus
6x - 8 = 6(4) - 8 = 24 - 8 = 16
Answer: 3.13; The regression line underpredicts the student's math test score.
Step-by-step explanation:
Given the equation of a regression model:
ŷ = −23.5 + 0.8534s,
where ŷ = predicted math score
s = IQ score
An actual math test score for a student is 73.5 with an IQ of 110.
Using the model to predict the score is f the student above ;
ŷ = −23.5 + 0.8534(110)
ŷ = −23.5 + 93.874
y = 70.374
Actual score = 73.5
Hence, since the actual score is greater Than the predicted score, then the model underpredicted the score by
Residual = actual - predicted = (73.5 - 70.374) = 3.126 = 3.13
Answer:
uh the area is 45 for the first one because 15*9 is 135 and 15*6 is 90 because you get 6 from 15-9 to get the length for the triangle. Then 135-90 is 45.
Step-by-step explanation:
The area for the second shape is 114 because you will take 14 multiplied by 12 and you get 168, then you will take 6*9 which is 54 and subtract that from 168, and you should get 114.
The area for the third shape is i dont even know because it doesnt give numbers unless your trying to find it with the letters but at least you got the first two
