The probability of you running into a Mankey Pokemon and then a Pidgey Pokemonis 4/27.
First, let's simplify the inequality as much as we can:
-4x + 7 > 15
-4x > 8
Divide by -4:
x < -2
Answer:
There is sufficient evidence that fuel economy goal has been attained.
Step-by-step explanation:
The hypothesis :
H0 : μ < 30.2
H1 : μ ≥ 30.2
The test statistic :
(xbar - μ) ÷ (s/√(n))
xbar = 32.12 ; s = 4.83 ; n = 50
Test statistic :
(32.12 - 30.2) ÷ (4.83/√(50))
1.92 ÷ 0.6830651
T = 2.811
Using the Pvalue from test statistic calculator :
Since we used the sample standard deviation, we use the T distribution
df = n - 1 = 50 - 1 = 49
Pvalue(2.811, 49) ; one tailed = 0.00354
At α = 0.05
Pvalue < α ; then we reject the null and conclude that there is sufficient evidence that fuel economy goal has been attained
Answer:
The experimental probability would be equal to the number of times the event happened over the number of times it was attempted. In this case, the experiment was tried 48 times, and only 6 times did it land on 2. The experimental probability is 6/48, which simplified to 1/8.
A) profit is 8$, the price increases 8$ every time or each pie is $4
B)N times 4= P
C) 15 times 4= $60 Profit. Because each pie is 4$
D) if 144$ are made and each pie is $4, you’d divide 144 by 4= 36. 36 Pies were sold.
I hope this is correct and helps :)
