Answer:
24
Step-by-step explanation:
Initially, there were 80 runners in the race. After the first half, 1/5 of them dropped out (given). Therefore, 4/5*80=64 runners remain. In the second half, 5/8 of these 64 runners drop out, meaning 3/8*64=24 runners finished the race.

One number is equal to the square of another. Find the numbers if both are positive and their sum is 90.
Answer:
x = y^2
:
Find the numbers if both are positive and their sum is 12
x + y = 12
replace x with y^2, you have a quadratic equation
y^2 + y - 12 = 0
Step-by-step explanation:
Factors to
(y+4)(y-3) = 0
The positive solution is all they want here
y = 3
then
x = 3^2
x = 9
;
they add up to 12

find the surface area of a cube with side edges of 9in. show steps
Answer:
486 sq. in
Step-by-step explanation:
Find the area of one face
Area = s^2
s = 9 in
Area = 9^2
Area = 81
Area 6 sides
There are 6 sides to a cube. So if you have the area of 1 side, you need only multiply by 6 to get the area of the cube
Area = 6 * 81
Area = 486

A chef was preparing for an event. The event was scheduled to have 100 guests in attendance. The chef had a rate of preparing meals for 10 guests every 1 and ½ hrs. At this rate, how many hrs. would it take the chef to prepare the meals for the 100 guests that were scheduled to be at the event?
Answer:
15 hours
Step-by-step explanation:
10 guests - 1.5 hours
1 guest - 1.5 / 10 = 0.15 hours
100 guests - 0.15 x 100 = 15 hours

A spinner is spun 77 times and stops on the color green 17 times. Calculate the experimental probability of the spinner stopping on the color green.
Answer:
[tex]\boxed {\boxed {\sf \ \frac {17}{77}}}}[/tex]
Step-by-step explanation:
The experimental probability is the probability of an event occurring in an experiment that was conducted. It is the ratio of the times an event occurred to the total trials.
[tex]P(event)= \frac{ number \ of times \ event \ occurs} {total \ number \ of \ trials}[/tex]
We are trying to find the experimental probability of landing on green.
The spinner was spun 77 times. This is the total number of trials. The spinner landed on green 17 times. This is the event.[tex]P(green)= \frac{17}{77}[/tex]
This fraction cannot be simplified any further, so the experimental probability of landing on the color green is 17/77

A large home improvement store is considering expanding its selection of moving products, such as cardboard boxes and packing tape. The store constructs a 90% confidence interval to estimate the proportion of all customers who have moved houses at least once in the last five years. In the random sample of 620 customers, 201 (32.4%) replied that they had moved at least once in the last five years. The sample yielded the 90% confidence interval (0.293, 0.355) for the proportion of all customers who have moved in the past five years. What is the correct interpretation of this confidence interval
The correct interpretation of the confidence interval is 90% confidence that the true proportion of all customers who have moved in the past five years is between 0.293 and 0.355.
The confidence interval is also not a guarantee that the true proportion is between 0.293 and 0.355. It is simply a statement of our confidence that the interval contains the true proportion.
This means that if the study were repeated many times, and constructed a 90% confidence interval each time, then 90% of the intervals would contain the true proportion.
In this case, the sample proportion is 0.324, which is within the confidence interval. This means that the sample data is consistent with the confidence interval. However, the sample proportion could be outside of the confidence interval if we had a different sample.
