Answer:

f

Step-by-step explanation:

sum of 15 and -6 is 11

-3 times -2 is 6 because the negatives cancel out

6 plus the 5 left in the parenthesis is 11

brainiest pls

Answer:

13

Step-by-step explanation:

[tex] \sqrt{ {(7 - 2)}^{2} + {( - 5 - 7)}^{2} } = 13[/tex]

Answer:

The expected number of red balls in the sample is 1.2857.

Step-by-step explanation:

The balls are chosen without replacement from the sample, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The expected value of the hypergeometric distribution is:

[tex]E(X) = \frac{nk}{N}[/tex]

3 red balls in the sample:

This means that [tex]k = 3[/tex]

3 balls are drawn:

This means that [tex]n = 3[/tex]

Total of 3 + 4 = 7 balls:

This means that [tex]N = 7[/tex]

What is the expected number of red balls in the sample?

[tex]E(X) = \frac{nk}{N} = \frac{3*3}{7} = 1.2857[/tex]

The expected number of red balls in the sample is 1.2857.

Answer:

[tex]f(g(-4)) = 18[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 4x + 6[/tex]

[tex]g(x) = x^2 + x - 9[/tex]

Required

Find f(g(-4))

First, calculate f(g(x))

We have:

[tex]f(x) = 4x + 6[/tex]

[tex]f(g(x)) = 4g(x) + 6[/tex]

Substitute: [tex]g(x) = x^2 + x - 9[/tex]

[tex]f(g(x)) = 4[x^2 + x - 9] + 6[/tex]

Open bracket

[tex]f(g(x)) = 4x^2 + 4x - 36 + 6[/tex]

[tex]f(g(x)) = 4x^2 + 4x-30[/tex]

Substitute [tex]-4[/tex] for [tex]x[/tex]

[tex]f(g(-4)) = 4*(-4)^2 + 4*(-4)-30[/tex]

[tex]f(g(-4)) = 64 -16 -30[/tex]

[tex]f(g(-4)) = 18[/tex]

Answer: Step-by-step explanation:

Answer:

75 students

Step-by-step explanation:

From the table, we can calculate the total number of students surveyed by Michael:

Total student surveyed = 13 + 15 + 32 = 60 students

We can see that out of the 60 students, 15 students played exactly one sport. Hence:

Proportion of students playing exactly one sport = 15 / 60 = 0.25

Based on the result of the survey, if they are 300 students, number of students playing exactly one sport is:

Number of students playing exactly one sport = proportion * total students = 0.25 * 300 students = 75 students

Answer:

[tex] \displaystyle23.125 \: \text{pounds}[/tex]

Step-by-step explanation:

we are given that,

in order to figure out the weight of the larger bicycle we can consider using equation

let the weight of the larger bicycle be L

according to the second condition

we acquire

[tex] \displaystyle L = 18.5 \times 1\frac{1}{4} [/tex]

to simplify the mixed fraction to improper fraction we can use the formula given by

[tex] \displaystyle \rm c\frac{a}{b} \xrightarrow{ \text{improper fraction}} \frac{b \times c + a}{b} [/tex]

by using the formula we get

[tex] \displaystyle L = 18.5 \times \frac{5}{4} [/tex]

simplify multiplication:

[tex] \displaystyle L =\frac{92.5}{4} [/tex]

simplify division:

[tex] \displaystyle L =23.125[/tex]

hence,

the larger bicycle weighs 23.125 pounds

Answer:

x = -7/5

or x = -1.4

Step-by-step explanation:

2/10 - 4/5 = -3/5

-3/5 * 7 = -21/5

-21/5 ÷ 3 = -7/5

Answer:

$ 80 000

Step-by-step explanation:

provident fund -- x

Wife -- 1/2 of x

Son -- 1/4 of x

Two brothers -- x - (x/2 - x/4)

Therefore, x - (x/2 - x/4) / 2 = 10 000

x = 80 000

Therefore, the amount of provident fund is $ 80 000

Thenks and mark me brainliest :)

Answer:

3/4

Step-by-step explanation:

1 1/2

3/2 make this 6/4 so you can have a common denominator

3/4

Then you subtract and boom 3/4 it also says in the problem lol
