There is a higher chance that the dad is right because he is betting on a pretty much 50/50 chance while the mom is betting on a 25% chance
Answer:
The significance level is
and since we are conducting a right tailed test we need to find a critical value who accumulate 0.01 of the area in the right of the normal standard distribution and we got:

So we reject the null hypothesis is 
Step-by-step explanation:
For this case we define the random variable X as the number of entry-level swimmers and we are interested about the true population mean for this variable . On specific we want to test this:
Null hypothesis: 
Alternative hypothesis: 
And the statistic is given by:

The significance level is
and since we are conducting a right tailed test we need to find a critical value who accumulate 0.01 of the area in the right of the normal standard distribution and we got:

So we reject the null hypothesis is 
Answer:
She probably was supposed to multiply, instead of add.
Step-by-step explanation:
First multiply 24 and 32, which is 768.
Second multiply 768 and 12, which is 9216
9216 is the answer.
ANSWER
Katnis is right
EXPLANATION
We use the Remainder Theorem to check if she is right.
According to the Remainder Theorem, if the polynomial function,

is divided by x+1, then the remainder is given by

We substitute x=-1 into the function to obtain,

We simplify to get:



Katnis is right because the remainder is zero
<u>Answer: </u>
Chance bought a surf board for 249. Now it's on sale for 221.10 and 11.20% is the discount.
<u>Solution:
</u>
Step 1:
Bought price= RS.249
Sale price=RS.221.10
Step 2:
Discount = bought price - sales price
Discount = 249 - 221.10
Discount = 27.9
Step 3:
Discount Percent = 
Substitute the value for Discount which we found in step 2 in the above formulae
Discount Percent = 
On simplification, we get

Discount Percent = 11.20%
Result:
Hence from the given data, we got the discount percent is 11.20%
