Answer:
Graph A is a function, and Graph B is not
Step-by-step explanation:
A function is when each x-value (aka input) has 1 corresponding y-value (or output).
We see that graph 1 is linear, and that each x-value has it's own y-value, and not multiple y-values.
However, Graph B curves, making it so some of the x-values have more than 1 y-value.
Answer:
Step-by-step explanation:
Given that a nutrition lab tested 40 hot dogs to see if their mean sodium content was less than the 325-mg upper limit set by regulations for "reduced sodium" franks
90% confidence interval is
(317.2, 326.8)mg.
Using confidence intervals,we can check whether null hypothesis is true.
Here
(left tailed test at 10% significance level)
We check whether confidence interval 90% contains the mean value.
We find 325 belongs to the confidence interval
Hence H0 is true
The hot dogs do not satisfy.
This is a problem of guess and check; there's no easier way to do it.But in this case you must have an odd number of nickels to make the 5 cents, so your answer is 9 nickels.you can check this by multiplying each one by .05:
9*.05=.45
the rest of the coins left, are 8 of them, and their dimes.
.10*8=.80
.80+.45= 1.25
This would be Delores because it goes katy, Delores, Alex, Sam, Beth
