Answer: how'd you do that
Step-by-step explanation:
360 - 4x - (x+40) - (x+10) = A
A = 360 - 4x - x - 40 - x - 10
A = 310 - 6x
A = 142
Answer:
The probability that any 7 randomly chosen parking spots have 2 SUVs and 5 trucks or 3 SUVs and 4 trucks is 49/60
The probability that of any 7 randomly chosen vehicles, exactly 1 is an SUV is = 7/40
Step-by-step explanation:
probability of taking 7 vehicles from 10 vehicles = 10C₇
number of ways taking 2 SUVs and 5 trucks = 3C₂* 7C₅ = 63
number of ways taking 3 SUVs and 4 trucks =3C₁*7C₄ = 35
number of ways taking 2 SUVs and 5 trucks or 3 SUVs and 4 trucks = 63 + 35 = 98
The probability that any 7 randomly chosen parking spots have 2 SUVs and 5 trucks or 3 SUVs and 4 trucks is = 98/120 = 49/60
number of ways taking 7 randomly chosen vehicles, exactly 1 is an SUV = 3C₁*7C₆ = 21
The probability that of any 7 randomly chosen vehicles, exactly 1 is an SUV is 21/120 = 7/40
Answer:
Here's wh as t I found
(X-1)²+(y+4)²=4
Step-by-step explanation:
(x-h)²+(y-k)²=r² with the center being at the point (h,k)
and radius being r.
(x-1)²+(y-(-4))²=2²
(x-1)²+(y+4)²=4
Answer:
9 / 20
Step-by-step explanation:
We can form a ratio with the information "for every 25 ml of orange juice you need 30 ml of apple juice and 45 ml of coconut milk"
25 : 30 : 45
Total = 100
Coconut milk = 45 ml
45 / 100 = 9 / 20
