Dillo says that the value of 12 - 3^2 is 81. how did he get that answer?

Answers

Answer:

3^2 is 9, 12-9 is 3, so Dillo is wrong

Step-by-step explanation:

Answer:

As the statement indicates that diallo says that the value of 12-3 to the second power is 81, it means that he subtracted 3 from 12 which is equal to 9. Also, the value of 12-3 to the second power means that he calculed the value of 9 squared which is 81.

b. there were more lightbulbs in the dot plot for brand a than in the dot plot for brand b

c. the mean for brand b is higher than the mean for brand a

d. the mean for brand a is higher than the mean for brand b

Answers

Answer:

Step-by-step explanation:

I dont really know so hope its right.

Answer:

C. The mean for brand B is higher than brand A.

Step-by-step explanation:

What we're looking for is the true statement of these 4.

We already know B is out, because there were 11 lightbulbs on brand B, and 10 on brand A.

Because of that, A is also out, because the means cannot be the same.

As a result, only C and D remain.

Now, add the 10 dots on brand A.

((1000 * 1) + (1100 * 2) + (1200 * 3) + (1300 * 4))/10

(1000 + 2200 + 3600 + 5200)/10

(3200 + 3600 + 5200)/10

(6800 + 5200)/10

12000/10

Brand A has an average of 1200 hours/lightbulb

Then, add the 11 on brand B

((1400 * 1) + (1500 * 4) + (1600 * 2) + (1700 * 1) + (1800 * 1) + (1900 * 1))/11

(1400 + 6000 + 3200 + 1700 + 1800 + 1900)/11

(7400 + 3200 + 1700 + 1800 + 1900)/11

(10600 + 1700 + 1800 + 1900)/11

(12300 + 1800 + 1900)/11

(14100 + 1900)/11

16000/11

Brand B has an average of 1454 hours 27 minutes 16 seconds 364 milliseconds/lightbulb

Comparing the two averages, we come to the realization that D is out because Brand A's average was less than Brand B's.

That leaves C as our answer.

When you are lining up the ratios, make sure they are aligning each other with the same unit.

13) Ok so if you run 1 mile in 8 minutes, the ratio will be 1:8. So you do

8(5) = 40 minutes

You take 40 minutes to run 5 miles.

( because of every 8 minutes you run one mile so you will multiply the amount of minutes(8) by the amount of miles(5).)

14) The ratio for this one is 1:12.5.

You work backwards to find this answer

400/32 (divide 32 into 400)

In one hour you earn 12.5.

To be sure check your answer like this

12.5*32= 400

15) For this one I’m not too sure (someone correct me if I’m wrong) I think the 24 oz would be a better buy.

The 24 oz cost $1.40 while the 32 oz cost $3.09 thats a $1.69 difference in price. If you wanted to get three loafs but you only have 5 dollars. Your best choice would be the 24oz because

$1.40*3 = $4.20
$3.09*3 = $9.27

In this case you will get three loafs for just under 5 dollars making the 24 oz a better buy.

( you multiply the price of one loaf by the amount of loafs you want)

Hope this helped :)

The ratio equivalent to the ratio 4:16 is 1:4.

What is the ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

The given ratio is 4:16.

Here, 4:16 can be written as 4/16

Divide both the numerator and denominator by 4, we get

1/4

So, 1/4 can be written in ratio as 1:4

Therefore, the ratio equivalent to the ratio 4:16 is 1:4.
