Answer:

b

Step-by-step explanation:

a) The probability that Sam will be upgraded exactly 3 times in his next 20 flights is 19.01 %

b) The probability that Sam will be upgraded at most 4 times in his next 20 flights is 95.68 %

c) The probability that Sam’s first upgrade will occur on the third flight is 0.0729

What is a Binomial Distribution?

The binomial distribution is a type of probability distribution that predicts the likelihood of obtaining one of two outcomes given a set of inputs. It summarizes the number of tries where each trial has the equal chance of producing the same result.

The formula for Binomial Distribution is given by

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ

where

n = number of trials

x = number of successes

p = probability of getting a success in one trial

q = probability of getting a failure in one trial

q = 1 - p

Given data ,

Let the probability of getting a coach-class ticket be p

The value of p = 0.10

a)

The probability that Sam will be upgraded exactly 3 times in his next 20 flights

The number of trials = 20

The probability of success p = 0.10

The probability of failure q = 1 - p

The probability of failure q = 0.90

x = 3

Substituting the values in the equation , we get

P ( 3 ) = [ 20! / ( 17 )! 3! ] ( 0.10 )³ ( 0.90 )¹⁷

P ( 3 ) = 0.1901

P ( 3 ) = 19.01 %

b)

The probability that Sam will be upgraded at most 4 times in his next 20 flights

The number of trials = 20

The probability of success p = 0.10

The probability of failure q = 1 - p

The probability of failure q = 0.90

x ≤ 4

Substituting the values in the equation , we get

P ( x ≤ 4 ) = [ 20! / ( 16 )! 4! ] ( 0.10 )⁴ ( 0.90 )¹⁶

P ( x ≤ 4 ) = 0.9568

P ( x ≤ 4 ) = 95.68 %

c)

The probability that Sam’s first upgrade will occur on the third flight

A = ( 0.9 ) ( 0.9 ) ( 0.9 ) ( 0.1 )

A = 0.0729

A = 7.29 %

Hence , the solution is calculated by binomial distribution

Answer: x= 47 (If that says 3x+2)(the picture is a little blurry)

Step-by-step explanation:

Linear pairs of angles sum to 180.

37+(3x+2) =180

Combine like terms

39+ 3x = 180

Subtract 39 from both sides

3x = 141

Divide both sides by 3

Step-by-step explanation:

First we multiply by 4. We will get: -16x-12>36

Then we add 12 to both sides. We'll get -16x>48

Then we divide by -16. 48 divided by -16 is -3.

Answer:

g(f(3)) = 49

Step-by-step explanation:

Evaluate f(3), then substitute the value obtained into g(x) , that is

f(3) = 2(3) + 1 = 6 + 1 = 7, then

g(7) = 7² = 49

Answer:

Wendell only has $12 in nickels and dimes

Let Wendell have x dimes

If Wendell has 3 times as many nickels as dimes, how many dimes does he have?

Number of nickels = 3x

dime 10 c

nickel 5c

10x+5*3x = 1200 ( $12=1200 c)

25x = 1200

x= 48 number of dimes

Answer:

576.6

(look at the number by the 10th place and round)

The value of 576.558 after rounding to the nearest tenth-place value is

576.6.

Option A is the correct answer.

The place value of a number is given as:

Example:

1234.567

1 = thousand place value

2 = hundred place value

3 = tens place value

4 = ones place value

5 = tenths place value

6 = hundredths place value

7 = thousandths place value

We have,

576.558

The number in the tenth place is 5 bolded underscore.

576.558

Now,

The next value is 5 which is greater or equal to 5 so we will change the tenth place value 5 into 6.

If the next value was 4 or less we will keep the tenth place value 5 as 5.

Now,

The value of 576.558 after rounding to the nearest tenth-place value is

576.6.

Thus,

The value of 576.558 after rounding to the nearest tenth-place value is

576.6.

Option A is the correct answer.

Step-by-step explanation:

center (-1, -2) , trough point ( 6, 4)

equation of the circle

r² = (x-h)²+(y-k)², where (h, k) are the coordinate of a circle so h=-1, k=-2

r² =(x+1)²+(y+2)², but (x, y ) are coordinates for any point on the circle so x=6 and y= 4

r² =(6+1)²+(4+2)²

r²= 7² +6²

r²= 85

so the equation is

(x+1)²+(y+2)²= 85

to find the points on the circle substitute in the equation x and y

(-10+1)²+(0+2)²= 85 ; 85=85 true

so the pint on the circle is (-10, 0)

Answer:

Step-by-step explanation:

future value: F = $64,700

present value: P = x

annual interest rate: r = 2.18%

compounding periods per year: n = 365

[tex] F = P(1 + \dfrac{r}{n})^{nt} [/tex]

[tex] 64,700 = P(1 + \dfrac{0.0218}{365})^{365 \times 14} [/tex]

[tex] 64,700 = P(1 + 0.0000597260274)^{5110} [/tex]

[tex] 64,700 = P(1.0000597260274)^{5110} [/tex]
