Answer:

**Answer:**

c. One sided t-test

**Step-by-step explanation:**

One sided t test because we want to compare two means and alternative hypothesis is directional.

A professor at a university wants to estimate the average number of hours of sleep the students get during exam week. The professor wants to find a sample mean that is within 4.266 hours of the true average for all college students at the university with 99% conconfidence. If the professor knows the standard deviation of the sleep times for all college students is 2.539, what sample size will need to be taken

**Here we will show you step-by-step with detailed explanation how to calculate 48 divided by 32 using long division.**

**Before you continue, note that in the problem 48 divided by 32, the numbers are defined as follows:**

**48 = dividend**

**32 = divisor**

** **

**Step 1:**

**Start by setting it up with the divisor 32 on the left side and the dividend 48 on the right side like this:**

** **

** 3 2 ⟌ 4 8 **

**Step 2:**

**The divisor (32) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:**

** 0 **

** 3 2 ⟌ 4 8 **

**Step 3:**

**Multiply the divisor by the result in the previous step (32 x 0 = 0) and write that answer below the dividend.**

** 0 **

** 3 2 ⟌ 4 8 **

** 0 **

**Step 4:**

**Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.**

** 0 **

** 3 2 ⟌ 4 8 **

** - 0 **

** 4 **

**Step 5:**

**Move down the 2nd digit of the dividend (8) like this:**

** 0 **

** 3 2 ⟌ 4 8 **

** - 0 **

** 4 8 **

**Step 6:**

**The divisor (32) goes into the bottom number (48), 1 time(s). Therefore, put 1 on top:**

** 0 1 **

** 3 2 ⟌ 4 8 **

** - 0 **

** 4 8 **

**Step 7:**

**Multiply the divisor by the result in the previous step (32 x 1 = 32) and write that answer at the bottom:**

** 0 1 **

** 3 2 ⟌ 4 8 **

** - 0 **

** 4 8 **

** 3 2 **

**Step 8:**

**Subtract the result in the previous step from the number written above it. (48 - 32 = 16) and write the answer at the bottom.**

** 0 1 **

** 3 2 ⟌ 4 8 **

** - 0 **

** 4 8 **

** - 3 2 **

** 1 6 **

**You are done, because there are no more digits to move down from the dividend.**

**The answer is the top number and the remainder is the bottom number.**

**Therefore, the answer to 48 divided by 32 calculated using Long Division is:**

**1**

**16 Remainder**

-3x - 10 > 14

X< -8

Answer choices: A: -3x>24 B:-3x>4 C: -3x> -4 D: -3x<24

**Answer:**

A: -3x > 24

**Step-by-step explanation:**

The missing step above is the result of adding 10 to both sides of the inequality.

____

*Comment on the solution of this inequality*

The solution shown is correct and gives correct results, but it requires that you divide by a negative number. That division can be by a positive number if the first step is to add x to both sides. Then the second step is to subtract 14 and you get ...

-24 > 3x

Division by a negative number is not required, and the direction of the inequality stays the same:

-8 > x

*Further comment on the solution*

Using left-pointing inequality symbols (< or ≤) arranges the left-right order of the operands the same way they are arranged on the number line. That is, for the solution to this inequality, all of the values of x are to the left of -8 on the number line. Writing the inequality in the form ...

x < -8

can help you see that. A bit of mental gymnastics is required when the inequality is written ...

-8 > x

and you want to graph or choose values of x that match this result. Of course, once you have -8>x, you can easily swap sides to make it x<-8.

A: -3x>24

The working is shown

we know that

[volume of rectangular prism]=L*W*h

L= 6 in prism A

volume of rectangular prism A=6*w*h

L=6*(1/2)------> L=3 in prism B

volume of rectangular prism B=3*w*h

so

volume of rectangular prism B=[volume of rectangular prism A]/2

the answer is

Volume of B is 1/2 volume of A

[volume of rectangular prism]=L*W*h

L= 6 in prism A

volume of rectangular prism A=6*w*h

L=6*(1/2)------> L=3 in prism B

volume of rectangular prism B=3*w*h

so

volume of rectangular prism B=[volume of rectangular prism A]/2

the answer is

Volume of B is 1/2 volume of A

Assume a standard deck of 52 cards with 4 suits of 13 cards each.

a. There are ways of being dealt a hand consisting of 8 hearts and 2 non-hearts, so the probability of being dealt such a hand is

b. This time, the non-hearts specifically belong to the suit of diamonds, for which there are ways of getting drawn, so the probability is
