Answer:
The claim that he rate of inaccurate orders is equal to 10% is supported by statistical evidnece at 5% level
Step-by-step explanation:
Given that in a study of the accuracy of fast food drive-through orders, one restaurant had 34 orders that were not accurate among 371 orders observed.
Sample proportion 
(Two tailed test at 5% significance level)
p difference = 
Std error if H0 is true = 
Test statistic Z = p diff/std error
=0.539
p value = 0.5899
Since p > 0.05 accept null hypothesis
The claim that he rate of inaccurate orders is equal to 10% is supported by statistical evidnece at 5% level
<span>log (M/N) = log M - log N
so log M - log N = 5
log (P/N) = log P - log N
so log P - log N = 7
If you subtract equation 2 from equation 1, you have log M - log P = -2
That means that log (M/P) = -2 ----> 10^-2 = M/P ---> P = 100M</span>
Answer:
Step-by-step explanation:
If all were dimes, you'd have $3.00. You have $0.40 less. Each dime that is replaced by a nickel subtracts $0.05, so there are $0.40/$0.05 = 8 nickels. That leaves 30-8 = 22 dimes.
You have 22 dimes and 8 nickels in your wallet.
Answer:
what do you want me to answer?
Step-by-step explanation:
N=3 m+7
n-2 m=1 | -2 m => n=1+2m
n=3 <span>m+7
</span><span>n=1+2 m
</span>
n=n
3m+7=1+2m |-7 and -2m
m = -6
n=1+2m
n=1+2*(-6)
n=-11
(-6,-11)
