Answer:

50 degrees

Step-by-step explanation:

APB is an inscribed angle, making its measure equal to 1/2 of the central angle. The central angle is given as 100 degrees, making the inscribed angle = 100/2 = 50 degrees

A restaurant gat an average of 14 calls in a 2 hr time period. What is the probability that at most 2 calls in 45 min period

rodikova [14]

Answer:

0.10512

Step-by-step explanation:

Given the following :

Mean number of calls(μ) in 2 hours = 14

2 hours = 60 * 2 = 120 minutes

Average number of calls in 45 minutes :

= (45 / 120) * 14

= 0.375 * 14

= 5.25

Now find P( x ≤ 2) = p(x = 0) + p( x = 1) + p(x = 2)

Using the poisson probability formula:

P(x, μ) = [(e^-μ) * (μ^x)] / x!

Where :

e = euler's constant

μ = 5.25

x = 0, 1, 2

Using the online poisson probability calculator :

P(x, 5.25) = P( x ≤ 2) = p(x = 0) + p(x = 1) + p(x = 2)

P(x, 5.25) = P( x ≤ 2) = 0.00525 + 0.02755 + 0.07232 = 0.10512

I found a place that will give me 20% discount if I spend over $50.My bill $75.How much money will I save? What is my final bill

kenny6666 [7]

Answer:

You will save: $15

Total cost: $60

Step-by-step explanation:

First turn the percent into a decimal.

To do so move the . over to the left twice.

20% - .20

Now multiply 75 by .20

75 x .20 = 15

So you will save $15

Now subtract 15 from 75

75 - 15 = 60

HELP PLEASE I do not know what to do i can only add photos of the answers i need help fast thank you

IRISSAK [1]

Answer:

f(x) = 3 if x ≤ -2

= 1 if x > -2 ⇒ attached figure

Step-by-step explanation:

* Lets explain how to answer the question

- For the part of the graph on the left side (2nd quadrant)

- There is a horizontal line start from x = -∞ and stop at x = -2

- The end of the line is black dot means x = -2 belongs to the function

- The horizontal line drawn at y = 3

∴ The equation of the horizontal line is y = 3

∴ The function represents this part of graph is y = 3 if x ≤ -2

- The other part of the graph is also horizontal line start from

x = -2 to x = ∞

- The end of the line is white dot means x = -2 does not belong

to the function

- The horizontal line drawn at y = 1

∴ The equation of the horizontal line is y = 1

∴ The function represents this part of graph is y = 1 if x > -2

* f(x) = 3 if x ≤ -2

= 1 if x > -2

- The answer is attached
