Answer:
the value of x is 200 I can't explain
Answer:
0.45576
Step-by-step explanation:
z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation.
Standard Deviation = √variance
Mean = 50
= √9
= 3
z = 51 - 50/3
= 0.11111
Probability value from Z-Table:
P(x<51) = 0.54424
P(x>51) = 1 - P(x<51)
= 1 - 0.54424
= 0.45576
The probability that the dealer will sell 51 or more cars is 0.45576
5m + 4m = 72
Combine like terms.
9m = 72
Divide both sides by 9.
m = 8
8x + 4y + 6 <= 70
x = # of salads
y = # of drinks
If he buys 4 salads then
8x + 4y + 6 <= 70
8(4) + 4y + 6 <70
32 + 4y + 6 <= 70
4y + 38 <= 70
4y <= 32
y <= 8
Answer
A. 8
