Answer:
It is binomial:
p= 0.75 = 75%
1-p = 0.25 = 25%
N = 10
k=7
"seven successes in 10 trials"
(10 choose 7) (0.75)^7 ( 0.25)^3 =
(10*9*8 / 3*2) * (0.75)^7 ( 0.25)^3 =
(5*3*8) (0.75)^7 ( 0.25)^3
120 (0.75)^7 ( 0.25)^3
= 0.25028228759765625
or just over 25%
Step-by-step explanation:
If 7x+3=24, that means x would be 3 so if you take 5-4x then that would be -7.
The volume of the room is: 1840 ft^3
Step-by-step explanation:
The volume is the capacity of a given figure.
Given
Width = w = 23 feet
Depth = d = 10 feet
Height = h = 8 feet
The formula for volume is:
The volume of the room is: 1840 ft^3

Every triangle’s inner angles’ addition equals to 180°
So if we find the x:
38°+x+2°+x=180°
40°+2x=180°
2x=180°-40°=140°
x=140°/2
x=70°
Now if we find the I hope this helped :)
