what does The standard deviation mean ?

Answer:

80%

Step-by-step explanation:

100%= 25/25. 1 donut = 5%. So you have 20 donuts left x 5.

Answer:

80% are left.

Step-by-step explanation:

So 100 donuts would be 100%. To get to 100 you need to multiply 25x4. Then you also need to multiply 5x4=20. Since it is the 5 that are eaten, you subtract 20 from 100 and get 80, so you are left with 80% of the donuts.

Answer:

Option 4 is correct

Step-by-step explanation:

Here, we want to select from the options, the dataset that is represented on the histogram

From what we have in the question, there is a range from 60 to 100

Also, there are no terms between 70 and 80

option 1 is wrong as we can see terms between 70 and 80

option 2 is also wrong for this reason

option 3 is incorrect ; looking at the frequency, the numbers between 60 and 70 should be 5 only and we have 6 in that set

Option 4 is the correct answer

Answer: 3

Step-by-step explanation:

The time at which the minimum likely occurred is: A. n = 2(t - 2)² + 7: 12 Pm.

First of all, we would rewrite the equation by factorizing in order to reveal the minimum number of customers:

n = 2t² - 8t + 15

n = 2t² - 8t + 8 + 7

n = 2t² - 4t - 4t + 8 + 15 - 8

n = 2(t² - 4t + 4) + 15 - 8

n = 2(t² - 4t + 4) + 7

n = 2(t - 2)² + 7

When n = 2, we have:

n = 2(2 - 2)² + 7

n = 7.

Thus, the minimum likely occurred at n = 2(t - 2)² + 7: 12 Pm.

Complete Question:

The number of customers in a store during the midday hours of 10 a.m. to 5 p.m. can be modeled by this function n = 2t² - 8t + 15, where n is the number of customers t hours after 10 a.m. Rewrite the equation to reveal the minimum number of customers. At what time does that minimum occur?

A. n = 2(t - 2)² + 7: 12 Pm.

B. n = 2(t - 2)² + 15: 2 Pm.

C. n = 2(t - 2)² + 7: 3 Pm.

D. n = 2(t - 4)² + 1: 4 Pm.

Answer:

β = 110

Step-by-step explanation:

Here, we want to find the value of beta

From the diagram;

70 + β = 180

The reason for this is that the sum of angles on a straight line is 180

Thus, we have that

β = 180-70

β = 110

Step-by-step explanation:

i took the test and my teacher explained this.

The probability of each outcome in the sample space = 1/2.

What is probability?

Probability is the chance of happening a situation or event.

Here, the probability to get a single gift card is 1/4.

A student can pick two cards, one at a time without any replacement.

Hence, the probability of the student to pick a second card is 1/3.

Hence, the probability of a student to pick two cards = 1/4 × 1/3 = 1/12.

Here, a student might select any of these combinations {(1, 2), (1, 3), (1, 4), (2, 3), (2, 4), (3, 4)}.

Therefore, the probability of each outcome in the sample space = 1/12 × 6 = 1/2.
