find the values the thing like beta
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

Okay so ur at a party and they have donuts, 5/25 of the donuts are eaten. What percent of them are left?
If it's not too much trouble could you explain how to solve it? If not I guess I'll live:(
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.

Select the correct answer. 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, 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. B. C. D.
The time at which the minimum likely occurred is: A. n = 2(t - 2)² + 7: 12 Pm.
How to determine when the minimum occur?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.

A teacher offers gift cards as a reward for classroom participation. The teacher places the gift cards from four different stores into a bag and mixes them well. A student gets to select two gift cards at random (one at a time and without replacement). Each outcome in the sample space for the random selection of two gift cards is equally likely. What is the probability of each outcome in the sample space?
1/16
1/6
1/4
1/2
Answer:
1/6
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.

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
