Answer:
17
Step-by-step explanation:
Variance=(standard deviation)^2
√289=standard deviation
Standard deviation=17
solve for y
2x−4y=10
-2x -2x subtract -2x from both sides
-4y = -2x +10
-4 -4 Divide both sides by -4 (coefficient on y)
y = -2/-4x + 10/-4
y = 1/2x - 5/2
the slope is the number on the x (coefficient)
and its 1/2
Answer:
1/3
Step-by-step explanation:
Answer:
L = 14/
<u>OR</u> 9.899
Step-by-step explanation:
cos(angle) = adjacent/ hypotenuse
hypotenuse = length of ladder
adjacent = 7 feet
length of ladder = L
1/L = cos(45)/7
L = 7/cos(45)
<u><em>MAKE SURE CALCULATOR IS IN DEGREE MODE</em></u>
L = 7/(
/2)
L = 14/
