Answer:
C. The mean increases by 1.4°.
Step-by-step explanation:
if you count the number of numbers in the set {58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57} it is 12 numbers.
The formula for mean is, [tex]mean=\frac{sum- of- the- terms}{number-of-terms}[/tex]
so if you add all the numbers here →, {58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57} you get a sum of 965.
Now 965 ➗12= 80.4166666667
If 98 is added we add 98 to 965 and get 1063.
That also means an additional number is being added so 12+1 = 13.
Now, 1063➗13= 81.7692307692
Ok now we approximate, 80.4166666667 is about 80.4 and 81.7692307692 is about 81.8.
Now we subtract 81.8-80.4 and get 1.4.
It was an increase of 1.4 in the mean so the answer is C.
SORRY IF MY EXPLAINING IS BAD ITS MY 1ST OR 2ND TIME EVER ANSWERING!! :)Grayson is packing 1-inch unit cubes in this box. What is the volume of the box? Fill in the blanks to complete the sentences.
Based on the information, we can infer that the volume of the cube is 1 cubic inch.
How to find the volume of the cube?To find the volume of the cube we must perform the following procedure:
Multiply:
Height * length * width = volume
Volume = 1 * 1 * 1We must bear in mind that the volume is counted in units of volume, so it can be cubic meters, cubic centimeters, cubic inches, cubic feet, among others. According to the above, the volume of this cube would be one cubic inch and its area would be one square inch.

rewrite in simplest terms: −10(−2p+10)−4p
Answer:
16p-100
Step-by-step explanation:
All we have to do is evaluate this expression.
The first step is to distribute -10 among the numbers in the parenthesis:
20p-100
We got 20p-100 from first multiplying -10 to -2p, which the negatives would cancel out and get 20p, and -10 multiplied by 10, which gets you -100
The next step is to subtract the 4p from the entire expression:
20p-100-4p
Or, we can rearrange this expression to make it clearer: 20p-4p-100
=16p-100
Hope this helps :)

can someone simplify 423/16 for me
(show work)
Step-by-step explanation:
1. Find the GCD (or HCF) of numerator and denominator
GCD of 423 and 16 is 1.
2. Divide both the numerator and denominator by the GCD
423 ÷ 1= 323
16 ÷ 1=16
3. Reduced fraction:
423
16
Therefore, 423/16 simplified to lowest terms is 423/16.
Answer: 423/16
Step-by-step explanation:
To be able to simplify 423/16, we need to find their greatest common factor (GCF). This is much easier to do using the smaller number, as it has less factors most of the time.
The factors of 16 are: 1, 2, 4, 8, 16.
If 423 shares one of these factors, we can simplify 423/16.
Since 2, 4, 8, and 16 are even numbers and 423 is odd, we already know that those are not factors of 423.
So, the only factor of 16 left that 423 shares is 1. If you divide 423/1 and 16/1, the fraction still is 423/16. This means that 423/16 is already in its simplest form.
If you want to find the decimal form of 423/16, it is 26.4375. 16 x 26 = 416. 416 + 16 = 432, which is greater than 423.
This means that 16 goes into 423 twenty-six times before it cannot fully go into it anymore.

You want to identify the stem and leaf plot for the 16 scores listed. Their minimum is 0.
Stem and leaf plotA typical stem and leaf plot lists the number of tens in a value at the left margin (the stem), then units digits (in order, least to greatest) of the values with that number of tens.
For example, the scores 0 and 5 both have 0 tens, so would be plotted as ...
0 | 0 5
where the leftmost 0 is the "stem" and the right two digits, 0 and 5, are the "leaves".
The plot will have as many leaves as there are values in the data set.
ApplicationThe two scores less than 10 are 0 and 5, so the first line of the stem-and-leaf plot will be ...
0 | 0 5 . . . . . . . . . eliminates choices B and C
There are 16 scores in the data set, so the plot will have a total of 16 leaves. (eliminates choice A).
The correct stem-and-leaf plot is choice D:
0 | 0 5
1 | 1 5 5 5
2 | 0 0 0 0 3 6
3 | 1 4 9 9

In a baseball tournament teams get 5 points for a win 3 points for a tie and 1 point for a loss. nathans team has 29 points.
a) use and organized list to show how many differnt combinations of wins,ties and losses nathans team could have.
b)what is the probability that nathans team had more losses than ties?
Answer:
a) Here are some different ways you can put it:
5pt, 5pt, 5pt, 5pt, 3pt, 3pt, 3pt (four 5pts and three 3pts)
3pt, 3pt, 3pt, 3pt, 3pt, 3pt, 3pt, 3pt, 5pt (eight 3 pts, one 5 pts)
1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt (twenty-nine 1pts lol)
5pt, 5pt, 5pt, 5pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt, 1pt (four 5pts, nine 1 pts)
And there are so many more combinations you can try out too!
(I'm confused. Do I have to show you all the combinations I can think of or only a few? Just ask me and I'll tell you more. Or other kind people can help you with more options.)
Step-by-step explanation:
a) You can just figure out how many points of each kind (wins, ties, losses) and add them all together to see if they are equal to the number you are going for.
ex) In a baseball tournament teams get 5 points for a win 3 points for a tie and 1 point for a loss. Boston's team has 32 points.
Here you would have to add up points until you reached 32, like this:
5pts + 5pts + 5pts + 5pts + 5pts + 5pts + 1pt + 1pt = 32 points
or 5pts + 5pts + 5pts + 5pts + 5pts + 3pts + 3pts + 3pts + 3pts = 32 points
b) Sorry I'm not so sure about this one because I don't know if I'm supposed to write the answer or write a percentage or fraction or something. Sorry again!

All faces of a bench except the two faces that rest on the ground will be coated with water-resistant paint. The bench is a right prism. What is the total area to be coated with the paint? Show your work.
Answer:
Step-by-step explanation:
234 is the answer
The total area to be painted is 8,316 square inches.
How to calculate total area?The bench has a rectangular base with dimensions 63 in by 14 in. The height of the bench is 54 in. The two faces that rest on the ground do not need to be coated with paint, so the total area to be coated is the sum of the areas of the four remaining faces.
The area of one of the longer faces is:
63 in × 54 in = 3,402 in²
The area of the other longer face is the same, so the total area of the longer faces is:
2 × 3,402 in² = 6,804 in²
The area of one of the shorter faces is:
14 in × 54 in = 756 in²
The area of the other shorter face is the same, so the total area of the shorter faces is:
2 × 756 in² = 1,512 in²
The total area to be coated with paint is the sum of the areas of the four remaining faces:
6,804 in² + 1,512 in² = 8,316 in²
Therefore, the total area to be coated with paint is 8,316 square inches.

Hozumi and Petra each own a hybrid car. They decide to compare the gas mileage for each, and kept track of the weekly average fuel efficiency (in mpg, miles per gallon) for a period of 8 weeks. The results are shown in the tables.
a. 1.45
b. 2.25
c. 3.92
d. 5.37
Answer: 1.45
Step-by-step explanation
It probably should be 1.45 I suppose since if you look at the graph, there is 3 - 39 and in the second, 3 - 52 so if you divided 39 by 3 you'd get 14 and if you divided 52 by 3 you'd get 17.3333333 and if you divided 17.3333333 by 14, you'd get 1.23809523571, which is closest to 1.45. I think that this is probably the answer.

(Question 1)
Now let’s start counting the possible outcomes in an order.
0 wins and0 ties and 29 losses 1 tie and 26 losses2 ties and 23 losses3 ties and 20 losses4 ties and 17 losses5 ties and 14 losses6 ties and 11 losses7 ties and 8 losses8 ties and 5 losses9 ties and 2 losses1 win and 0 ties and 24 losses1 tie and 21 losses2 ties and 18 losses3 ties and 15 losses4 ties and 12 losses5 ties and 9 losses6 ties and 6 losses7 ties and 3 losses8 ties and 0 losses2 wins and0 ties and 19 losses1 tie and 16 losses2 ties and 13 losses3 ties and 10 losses4 ties and 7 losses5 ties and 4 losses6 ties and 1 loss3 wins and0 ties and 14 losses1 tie and 11 losses2 ties and 8 losses3 ties and 5 losses4 ties and 2 losses4 wins and0 ties and 9 losses1 tie and 6 losses2 ties and 3 losses3 ties and 0 losses5 wins and0 ties and 4 losses1 tie and 1 lossSo, totally there are 37 different combinations.
(Question 2)
Number of Losses that Nathan can have = 29/1
= 29 Losses
Number of Ties that Nathan can have = 29/3
= 9 Ties
Total = 29 + 9
= 38
Probability of Losses = 29/38
= 76% (Approximately)
Probability of Ties = 9/38
= 24% (Approximately)
We can easily figure out that the Probability of Losses is more than the Probability of Ties.
The Probability of Losses is more than Probability of Ties by —
Probability of Losses - probability of Ties = 76 - 24 = 52%
