PLEASE HELP! WILL MARK BRAINLIEST!

Mathematics
2 answers:
____ [38]4 years ago
4 0

Answer:

b. 75

Step-by-step explanation:

a(n) = a1 + d(n-1)

a(n) = 8.5 + 3.5(n - 1)

a(20) =  8.5 + 3.5(20 - 1)

a(20) =  8.5 + 3.5(19)

a(20) = 8.5  + 66.5

a(20) = 75

Answer:

75.

Step-by-step explanation:

The nth term = a1 + d(n  -1)

Therefore the 20th term = 8.5 + 3.5(20 - 1)

= 8.5 + 3.5 * 19

=  75

The percentage of people under the age of 18 was 23.5% in New York City, 25.8% in Chicago, and 26% in Los Angeles.
Hatshy [7]

Answer:

0.0158 = 1.58% probability that all of them are under 18.

Step-by-step explanation:

Probability of independent events:

If three events, A, B and C are independent, the probability of all happening is the multiplication of the probabilities of each happening, that is:

P(A \cap B \cap C) = P(A)P(B)P(C)

The percentage of people under the age of 18 was 23.5% in New York City, 25.8% in Chicago, and 26% in Los Angeles.

This means that P(A) = 0.235, P(B) = 0.258, P(C) = 0.26

If one person is selected from each city, what is the probability that all of them are under 18?

Since the three people are independent:

P(A \cap B \cap C) = 0.235*0.258*0.26 = 0.0158

0.0158 = 1.58% probability that all of them are under 18.

Look at the triangle below which of the following represents two of the angle measures of the triangle
Gelneren [198K]

Answer:

C. 60° and 80°

Step-by-step explanation:

Sum of triangle = 180°

Therefore,

8x + 4 + 6x - 2 + 10x + 10 = 180

Add like terms

8x + 6x + 10x + 4 - 2 + 10 = 180

24x + 12 = 180

24x = 180 - 12

24x = 168

x = 168/24

x = 7

Find each measure of the angles by substitute x = 7 into each expression

8x + 4 = 8(7) + 4 = 60°

6x - 2 = 6(7) - 2 = 40°

10x + 10 = 10(7) + 10 = 80°

The answer is 60° and 80°

Can someone help me with these functions
ryzh [129]

Answer:

Function 1:

The starting point is (0,0.5)

As x increases, y increases

Function 2:

The starting point is (0,3)

As x increases, y decreases

Step-by-step explanation:

In order to find the starting point, we need to plug in x=0.

y=0.5+3(0)\\\\y=0.5

y=3(0.5)^0\\\\y=3(1)\\\\y=3

As we plug in increasing numbers into function#1, the y-value increases

As we plug in increasing numbers into function #2, the y-value is decreasing
