Answer:

Step-by-step explanation:
The cost is given for <em>1 sweatshirt</em>. To find the cost of 15 sweatshirts, we need to multiply the expression by 15. Let's do this:

This is the expression that represents the cost of 15 sweatshirts.
Answer:
Option a) Type I error would occur if we reject null hypothesis and conclude that the average amount is greater than $3,200 when in fact the average amount is $3,200 or less.
Step-by-step explanation:
We are given the following information in the question:

where μ is the average amount of money in a savings account for a person aged 30 to 40.
Type I error:
- Type I error is also known as a “false positive” and is the error of rejecting a null hypothesis when it is actually true.
- In other words, this is the error of accepting an alternative hypothesis when the results can be attributed by null hypothesis.
- A type I error occurs during the hypothesis testing process when a null hypothesis is rejected, even though it is correct and should not be rejected.
Thus, in the above hypothesis type error will occur when we reject the null hypothesis even when it is true.
Option a) Type I error would occur if we reject null hypothesis and conclude that the average amount is greater than $3,200 when in fact the average amount is $3,200 or less.
Answer:
35.84
Step-by-step explanation:
You would take 19% of 30.12$ by doing 30.12x0.19 to get 5.72.
you then add 5.72 to 30.12 to get your total of 35.84$
9514 1404 393
Answer:
4
Step-by-step explanation:
The function is of even degree. You can tell this because the end behavior is the same at both ends.
There are at least 4 zeros. There are 2 zeros of multiplicity 1 and one zero of multiplicity 2.
The crossings of the x-axis at x=-2 and x=3 have no flat spot, so the multiplicity must be 1; not 3, 5, or some other odd number.
You can tell the zero at x=1 is even multiplicity, because the graph does not cross the x-axis there. You can tell the multiplicity is only 2 because the curve is not flat enough for it to be 4 or more.
A polynomial function with 4 real zeros has a minimum degree of 4.
Answer:
41.67πunits³
Step-by-step explanation:
Since we are not asked what to find, we can as well look for the volume of the cone.
Find the diagram of the cone attached
Volume of the cone = 1/3πr²h
h is the height of the cone
r is the radius of the cone
Volume of the cone = 1/3π(5)²(5)
Volume of the cone= 1/3π(125)
Volume of the cone = 125π/3
Volume of the cone = 41.67πunits³
