Solve 24 =y +17.5 y=

Answers

-6.5


17.5-24 you place the 24 near the 17.5 and make 24 a negative so the equation would be

y= 17.5-24

Answer:

[tex] \sf \: y = 6.5[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of y.

The equation is,

→ 24 = y + 17.5

Then the value of y will be,

→ 24 = y + 17.5

→ y + 17.5 = 24

→ y = 24 - 17.5

→ [ y = 6.5 ]

Hence, the value of y is 6.5.

The following table shows the data collected from a random sample of 100 middle school students on the number of hours they do household chores every week:

Number of Students 32 64 3 1


There are 1,500 students in the school. Based on the sample proportion, how many students in the school would be expected to do household chores for at least two hours every week?

A: 480
B: 960
C: 1,020
D: 1,440

PLS DONT ANSWER WITH A LINK! :) My answer ended of being 1,020 but I dont think its right pls help

Answers

Answer:

1020 students

Step-by-step explanation:

the key word is at least, this means anything under that number will not qualify. So that leaves 68 out of the 100 sample students. So if you want to have the same thing but with 1,500 students. Take off the 2 zeros at the end of 1500 and multiply by 68 getting your answer. This is because there is 2 zeros in 100, so to cancel out the 2 zeros in 100, just take out the 2 zeros in 1500 making it a lot easier.

The students in the school would be expected to do household chores for at least two hours every week with 1020 students.

We have given

Time (in hours)                  0–  1    2–3     4–5    6–7

Number of Students           32    64           3        1

What is the random sample?

A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.

The keyword is at least, this means anything under that number will not qualify.

So that leaves 68 out of the 100 sample students.

So if you want to have the same thing but with 1,500 students.

Take off the 2 zeros at the end of 1500 and multiply by 68 getting your answer.

This is because there is 2 zeros in 100, so to cancel out the 2 zeros in 100, just take out the 2 zeros in 1500 making it a lot easier.

A statistical question is defined as a question that can be answered by collecting data that vary.  Basically, it is a question that can be surveyed.  The question, "How many board games have you played in the past month?", is the only one that is statistical because multiple different answers can be given to this question.

How many mg of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel? Which of the following equations could be used to solve this?

Answers

Answer:

3.29 milligrams of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel.

Step-by-step explanation:

To determine how many mg of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel, the following calculations must be performed:

50 + 0.62X = 78

0.62X = 78 - 50

0.62X = 28

X = 28 / 0.62

X = 45.16

100 - 45.16 = 54.84

54.84 = 4

45.16 = X

45.16 x 4 / 54.84 = X

180.64 / 54.84 = X

3.29 = X

Therefore, 3.29 milligrams of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel.

Carla's library account showed that she owed $4.00 in late fees. She made a payment of $7.00. She then lost a library book and was assessed a $12.00 fine. If Carla then makes a payment of $20, what is her balance after the payment?

Answers

Answer:

$9

Step-by-step explanation:

ok so this is what she owes- **i'm 'separating' them to make it easier**

$4 and $12 so let's add those together-

4+12=$16 so she owes 16 dollars in fines and late fees

and let's remember that she paid $7 for her late fee and assuming that she gets her $3 back she has $3 so far then for the 12 dollar fine she pays 20 dollars, and we're assuming that she gets back $6

she should have $9 left

good luck :)
