The immproper fraction is 14/9. The mixed number is 1 5/9.
Answer:
x = 12.
Step-by-step explanation:
2x + 6 + 4x + 2 = 2(5x - 20) (The sum of the outer parallel sides = 2 * middle parallel line).
6x + 8 = 10x - 40
48 = 4x
x = 12.
3 divided by 4 is .75
so the answer is .75
because the quotient is the answer
Answer:
A
Step-by-step explanation:
You can make an infinite number of triangles with those three angle measures, because the side lengths can be different.
Answer:
834 chirps
Step-by-step explanation:
Given the data:
Chirps in 1 min Temperature (°F)
781 74
1039 85.9
1156 87.2
1218 87.8
1131 91.4
888 75.5
Using technology, the regression model obtained will be in the form :
y = bx + c
b = slope ; c = intercept
y = temperature ; x = chirps per minute
The regression model is :
ŷ= 43.28 + 0.0390x
If outside temperature, y = 76 ; x will be ;
76 = 43.28 + 0.0390x
76 - 43.28 = 0.0390x
32.72 = 0.0390x
x = 32.72 / 0.0390
x = 838.97435
x = 834 chirps per minute
