Answer:

a. Mean = 84.25. Median = 89. Mode = 89. b. Sum = 1554.

Step-by-step explanation:

a. Mean: add together 70, 89, 89, and 89, to get 337. Divide by 4 to get the mean, which is 84.25.

Median: The "middle" number, which is 89.

Mode: The number that occurs most often, which is 89.

b. 21 times 74 equals 1554. This is the sum of the test scores.

Hope this helps!

X=-9. To do this equation you had to do a multi-step problem solver teqnique. But I would recommend Khan Academy for any questions. My best advice would be for that. Or you can just try to simplify the equation down as much as possible. To do so, you'd have to multiply the first parentheses by -3. Which would equal: (-9x+-65) -(10+x) =35. Next you will add 65 to each side. But always remember if you to something on this side, you must always do it on the other side over the equal sign. Which would equal to: -9-(10+x) =100. So from here you will subract 10 to eliminate the number 10. Like so: -9x+x=90. So from here, you will just add the two x's together because, in math simplifying in the most important thing ever!: -10x/10=90/10. (The parentheses mean division btw) Then after dividing you will get x=-9. Hope that helps and after getting this through your head it's a piece of cake. Good luck

Need help on this ttm question ASAP

Answer:


Books should be kept in second box.

Step-by-step explanation:

If the sum of all  the weight of all books is between 4 and 6 pounds then it should be kept in first box

If the sum of all  the weight of all books is between 5 and 7 pounds then it should be kept in second box

If the sum of all  the weight of all books is between 8 and 9 pounds then it should be kept in first box .

Here sum of the weighs of all the  books = 3.1lb+2.4lb +0.75lb

                                                                     = 6.25 lb

Here we can see that 6.25 lb lies between 5 and 7  which is the weigh limit

for the second box

therefore we can keep the books in second  box.

Triangle IJK is similar to triangle LMN. Find the measure of side LM. Round your answer to the nearest tenth if necessary.
Andre45 [30]

Answer:

It's either 39.2 or 39.3 (a more accurate answer) because it depends on what you round by. since it's Delta Math, you should get 2 attempts.

Step-by-step explanation:

Since they are similar, they are proportional.

54/11=4.90909091 or 4.9

Multiply 11 by 4.90909091 and you get 54

Multiply 8 by 4.90909091 and you get 39.3

if you multiply by 4.9 you get 39.2
