Answer:

f-¹(x) = -⅕x - ⅘

Step-by-step explanation:

f(x) = -5x - 4 → x = -5y - 4 → 5y = - x - 4 → y = -⅕x - ⅘ → f-¹(x) = -⅕x - ⅘

Answer:

0.9167 = 91.67% probability that the entire batch will be accepted

Step-by-step explanation:

The CDs are chosen without replacement, which means that the hypergeometric distribution is used.

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]

2100 write-rewrite CDs, and 60 are defective.

This means, respectively, that [tex]N = 2100, k = 60[/tex]

3 of these CDs are randomly selected for testing

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

What is the probability that the entire batch will be accepted?

Probability of none defective, so P(X = 0).

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

[tex]P(X = 0) = h(0,2100,3,60) = \frac{C_{60,0}*C_{2040,3}}{C_{2100,3}} = 0.9167[/tex]

0.9167 = 91.67% probability that the entire batch will be accepted

Answer:

0.8980 = 89.80% probability that a randomly selected firm will earn less than 109 million dollars

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Distributed normally, mean of 90 million, standard deviation of 15 million.

This means that [tex]\mu = 90, \sigma = 15[/tex]

What is the probability that a randomly selected firm will earn less than 109 million dollars?

This is the pvalue of Z when X = 109. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{109 - 90}{15}[/tex]

[tex]Z = 1.27[/tex]

[tex]Z = 1.27[/tex] has a pvalue of 0.8980

0.8980 = 89.80% probability that a randomly selected firm will earn less than 109 million dollars

Step-by-step explanation:

hello there!

Remember all of the angles in a triangle will add up to equal 180 so to find the missing angle we subtract the given angles from 180

180 - 90 - 45 = 45 so the missing angle would equal 45

Answer:

g(30) = 71.8

Step-by-step explanation:

g(30) = 19.6 + 1.74(30)

The value of the g(30) is 71.8 if the function is g(x) = 19.60 + 1.74x

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

g(x)=19.60+1.74x

Plug x = 30

g(30) = 19.60+1.74(30)

g(30) = 19.60 + 52.2

g(30) = 71.8

Thus, the value of the g(30) is 71.8 if the function is g(x) = 19.60 + 1.74x

Answer:700

Step-by-step explanation:

Answer: He can make 688 beads, and 8 beads will be left.

Step-by-step explanation:

First, you need to divide 6,200 by 9.

        6,200 ÷ 9 = 688 R8.

688 will be the number of bracelets he can make, and the remainder, 8, will be the leftover beads because he doesn't have enough to make another bracelet.

          For the labels, it says, "How many bracelets can he make?" and," How many beads will be left?"

           The answers will be: 688 bracelets;8beads

Equation : 6,200÷9=x  6,200÷9=688 R8  x=688 bracelets;8 beads

Answer:

B = 40°

a = 23.0

b = 19.3

Step-by-step explanation:

✔️B = 180° - (90° + 50°) => sum of triangle

B = 40°

✔️Reference angle = 50°

Opp = a

Hypotenuse = 30

Adjacent = b

Find a by applying the trigonometric function, SOH:

Sin 50 = Opp/Hyp

Sin 50 = a/30

30 × Sin 50 = a

23.0 = a

a = 23.0 (nearest tenth)

To find b, apply CAH:

Cos 50 = Adj/Hyp

Cos 50 = b/30

30 × Cos 50 = b

b = 19.3 (nearest tenth)

Answer:

x=25 =18

Step-by-step explanation:

Right angle =90°

you are given 40, therefore 2x has to equal up to 50.

2x=50 divide both sides by 2

x=25

straight line=180°

you are given 90, therefore 5y has to equal to 90.

5y=90

divide both sides by 5

y=18
