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

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:

for the first one, go left 10, then down 7, and you have your point. for the second one, go left 5, then down 9, and you have your point.

Step-by-step explanation:

for the x-axis, negative means backwards

for the y-axis, negative means down

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.

Explanation:

The triangle is a special right triangle.

Since it has a 45° in one of the two unknown angles, the other angle is also 45°. This is called a 45-45-90 right triangle.

The rule for that special triangle is that the legs measure the same while the hypotenuse measures a multiplication of √2.

Since one leg is labeled 7 units, the other (which is x) is labeled 7 too.

The geometric mean of 5 and 36 is 13.42.

[tex]= \sqrt{5\times 36}\\\\ = \sqrt{180}[/tex]

= 13.42

Step 2 is incorrect. It should be -4x +2= -12

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:

Step-by-step explanation:

In this case, we use variables to represent the the cost of the big and the smaller boxes. Let x be the selling price of the big boxes while y be the selling price of the bigger boxes.

The total selling price of the smaller boxes is 20x. The total selling price of the bigger ones is 12y.

Now we know he is making a profit of $1,300

Hence in equation form, all the information above can be represented as:

20x + 12y = 1,300

Answer:

a. Slope (m): ⅓

b. y-intercept (b): 5

c. Equation: y = ⅓x + 5

Step-by-step explanation:

3a. Using two pairs from the table, say, (-3, 4) and (0, 5):

Slope = m = ∆y/∆x = (5 - 4)/(0 -(-3)) = 1/3

m = ⅓

b. y-intercept (b) is the value of y, when x = 0.

Thus, from the table, when x = 0, y = 5.

Therefore, y-intercept (b) = 5

c. Substitute m = ⅓, and b = 5 into y = mx + b

The equation is:

y = ⅓x + 5

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
