Answer:

A, B, C

Step-by-step explanation:

I'm not good at explaining, but whole numbers are all of the positive numbers. An integer is a whole number that can't be converted into a fraction. Also, This number is rational because it is, I can't explain it but I know that's the answer

A parallelogram has one angle that measures 80 degrees. What are the measures of the three other angles in the parallelogram?

san4es73 [151]

The opposite angle is also 80°. since consecutive angles must total 180, the other 2 angles are 100 each. 100+100+80+80=360, as needed for a parallelogram

Sammy bought 15.3 Liters of milk. She poured the milk equally into 5 bottles. There was 0.35 liters of milk left over. Calculate

Zanzabum

Answer:

The capacity of milk in 1 bottle is 2.99 liters

Step-by-step explanation:

Let us solve the question

∵ Sammy bought 15.3 liters of milk

∵ She poured the milk equally into 5 bottles

∵ There were 0.35 liters of milk leftover

→ At first, subtract the leftover from the quantity she bought to

find the capacity of the five bottles

∴ The capacity of the 5 bottles = 15.3 - 0.35

∴ The capacity of the 5 bottles = 14.95 liters

→ To find the capacity of each bottle divide the total capacity by 5

∴ The capacity in one bottle = 14.95 ÷ 5

∴ The capacity in one bottle = 2.99 liters

∴ The capacity of milk in 1 bottle is 2.99 liters

If the coefficient of correlation is .8, then the percentage of variation in the dependent variable explained by the estimated r

Olegator [25]

Answer:

64%

Step-by-step explanation:

The percentage of variation in the dependent variable explained by the estimated regression is calculated with the coefficient of correlation as follows:

First, square the coefficient of correlation: 0.8^2 = 0.64

And then, multiply this result by 100, so that, it is expressed as a percentage: 0.64*100 = 64%

A research student is working with a culture of bacteria that doubles in size every

ser-zykov [4K]

Answer:

$2^{24}*1000$ bacteria

Step-by-step explanation:

The generic form of an exponential function is: $f(n)=ar^n$ , where a is the initial amount, r is the rate, and n is the time.

In this case, the initial amount is 1000, so a = 1000. Also, the rate is 2 because the culture doubles in size every 5 minutes. However, our n is not just n; it's actually n/5 because the rate is doubling per 5 minutes, not per 1 minute. If it was per 1 minute, then the time would simply be n. Unfortunately, that's not the case here, so the exponent of r should be n/5, where n is the number of minutes that have passed.

Now, we have: $f(n)=1000(2)^{n/5}$

Since n is the number of minutes, we need to convert 2 hours to minutes:

2 hours * 60 min/hour = 120 minutes.

$f(120)=1000(2)^{120/5}=1000(2)^{24}=2^{24}*1000$ $f(120)=1000(2)^{120/5}=1000(2)^{24}=2^{24}*1000$

Thus, the answer is $2^{24}*1000$ bacteria.

Hope this helps!
