6 times _ equals 9
12 times _ equals 3
Answers
Answer:
6 times 1.5 equals 9. Essentially, this is just 1 and a half of 6, meaning you have 6, and half of 6, 3, together.
12 times 0.25 equals 3. Multiplying something by 0.25 has the same effect as dividing by 4, as both results in a quarter of the original number. Since 3 is a quarter, or 1/4 the size of 12, that means that multiplying it by 1/4 or 0.25 will give us 3.

If you spin the spinner 4 times, what is the best prediction possible for the number of times it will not land on green?
NO WRONG ANSWERS PLEASE.
Answers
Answer: 2
Step-by-step explanation:
Probability of not green: 1/2
0.5*4=2
Answer:
2 times
Step-by-step explanation:
The spinner is divided into 2 sections one being yellow, one being green. This implies a 1/2 or 50% chance of landing on yellow.
Spinning it 4 times means a 2/4 chance of landing on yellow, which is equal to 1/2. This means that the prediction is that you will land on yellow 2 out of the 4 total times

If a value of 80.8° is added to the data, how does the range change?
Answers
Answer:
The original data set would be:
57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
So to find the range you would do:
105 - 57 which equals 48.
So the range for the original data set would be 48.
The new data set adding 80.8:
57, 58, 61, 66, 71, 77, 80.8, 82, 91, 95, 100, 102, 105
So to find the range for the new data set you would do:
105 - 57 which would still equal 48.
So the range for the new data set would be 48.
The range for the original and new data set stayed the same.
Step-by-step explanation:
You're welcome.
Step 2: find the range
105 - 57 = 48
The range for the original data set is 48.
The new data set is adding 80.8
Step 1: find the new data set.
57, 58, 61, 66, 71, 77, 80.8, 82, 91, 95, 100, 102, 105
Step 2: find the range
105 - 57 = 48.
The range is still the same for the original and new data set.

When a number is decreased by 19%, the result is 66. What is the original number to the nearest tenth?
Answers
Answer:
80
step by step explanation:
when a number is decreased by 19 %, u calculate backwards, making the % to 119% of 66. Hence it becomes 78.54 to be exact, but in the nearest tenth, it becomes 80.
Answer:
81.48 (81.5 rounded)Step-by-step explanation:
from the question 66 is = 81%
(100% - 19% = 81)
so
66 : 81 * 100 = 81.48 (81.5 rounded)
Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $6100 and his stock in Company B was worth $6480. The stock in Company A has decreased 2% since last year and the stock in Company B has decreased 10%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answers
Investment in Company A by investor = $6100
Investment in Company B by investor = $6480
The decrease in value of the stock of company A is 2%
The decrease in value of the stock of company B is 10%
Value of wealth that investor lost in company A = 6100× 2/100
= 61×2
= $122
The decline in the value of the stock of company B = 6480×10/100
= 648×1/1
= $648
The total decline in the wealth of the investor= 122+648
= $770
The combined wealth of investor in both companies= 6100+6480
= $12580
Percentage of decline in the stock account of investor= 770×100/12580
= 77000/12580
= 6.1%
The total percentage decline in investor's stock account is 6.1%
