Jeremy received a basket containing 8 red and 4 green apples.

When he randomly selects and eats two apples from the basket, these are
events.

The probability that both of the apples Jeremy eats are green is
.

Answers

Answer:

It is more probable that he pick two red apples than green. Because their are more red apples thank green so the chances of him picking green apples are very slim.

Have a nice day/night!

This is an example of probability without replacement and can simply be done using the formula.

The probability that both apples he ate will be green is 1/12

Probability without replacement

This is done when we pick a value from a data set and does not replace it and hence affects the value of the original data set.

Data;

Red = 8Green = 4

Jeremy ate two apples from the basket and the probability this is green would be

[tex]8 + 4 = 12\\[/tex]

The number of green apples are = 4

[tex]\frac{4}{12} * \frac{3}{12} = \frac{12}{144} = \frac{1}{12}[/tex]

The probability that both apples he ate will be green is 1/12

Find the producer's surplus at market equilibrium for a product if its demand function is p = 121 − [tex]x^{2}[/tex] and its supply function is p = [tex]x^{2}[/tex] + 6x + 65. (Round your answer to the nearest cent.)

Answers

The market equilibrium is the point where the demand and supply functions are equal

The producer's surplus at market equilibrium for a product is #105

How to determine the producer's surplus

The functions are given as:

[tex]p = 121 - x^2[/tex]

[tex]p = x^2 + 6x + 65[/tex]

Equate both functions

[tex]x^2 + 6x + 65 = 121 - x^2[/tex]

Collect like terms

[tex]x^2 + x^2 + 6x + 65 - 121 = 0[/tex]

Evaluate the like terms

[tex]2x^2 + 6x -56 = 0[/tex]

Divide through by 2

[tex]x^2 + 3x -28 = 0[/tex]

Expand

[tex]x^2 + 7x - 4x - 28 = 0[/tex]

Factorize

[tex]x(x + 7) - 4(x +7)= 0[/tex]

Factor out x + 7

[tex](x - 4)(x +7)= 0[/tex]

Solve for x

x = 4 or x = -7

The number of units cannot be negative,

So, we have:

x = 4

Substitute 4 for x in [tex]p = 121 - x^2[/tex]

[tex]p = 121 - 4^2[/tex]

p = 105

Hence, the producer's surplus at market equilibrium for a product is #105

Parents pay $1,800.
What is the amount that the student will need to save every month in order to pay off the remaining costs in 10 months?
a. $525
b.$630
c.$1,200
d. $1,440

Answers

Answer:B $630 Per Month So B

Step-by-step explanation: $22,500-$10,000=$12,500-$4,400=$8,100-$1,800=$6,300/10Months=$630

Answer:

$690

Step-by-step explanation:

If the student will need to save every month in order to pay off the remaining costs in 10 months, the amount she will need to save per month is $690

Amount and interest

Given the following information from the question

The total cost of fee =  $23,500

Amount got as help;

An academic scholarship of $8,200.

Other scholarships and grants of $7.400.

Grandparents pay $1,000

Amount she had = 8200 + 7400 + 1000

Amount she had = $16600

Amount remaining = 23500 - 16600

Amount remaining = $6900

If the student will need to save every month in order to pay off the remaining costs in 10 months, the amount she will need to save per month is $690

hope helpful~

Answer:

Value of k is 74

Step-by-step explanation:

Here we have been provided with the values of n and w that is 4 and -6 respectively.

Equation that we have,

k = 5n² + w

Substituting the values of n and w in the equation,

[tex] \implies \: \sf{k \: = \: 5(4) {}^{2} \: + \: ( - 6)}[/tex]

[tex]\implies \: \sf{k \: = \: 5(4 \times 4) \: + \: ( - 6)}[/tex]

[tex] \implies \: \sf{k \: = \: 5 \: (16) \: + \: ( - 6)}[/tex]

Multiplying 16 by 5,

[tex]\implies \: \sf{k \: = \: 5 \: \times 16 \: + \: ( - 6)}[/tex]

[tex]\implies \: \sf{k \: = \: 80 \: + \: ( - 6)}[/tex]

[tex]\implies \: \sf{k \: = \: 80 \: - \:6)}[/tex]

Subtracting 6 from 80,

[tex]\implies \: \red{\bf{k \: = \: 74}}[/tex]

Therefore, value of k is 74..!!

Answers

Answer:

Step-by-step explanation:

We are given the expression [tex]\displaystyle \large{x^2-9}[/tex]:—

To factor this expression, we have a formula for it which is difference of two squares:—

[tex]\displaystyle \large{a^2-b^2=(a+b)(a-b)}[/tex]

You can also swap from [tex]\displaystyle \large{(a+b)(a-b)}[/tex] to [tex]\displaystyle \large{(a-b)(a+b)}[/tex] via multiplication property.

From the expression, factor using the formula above:—

[tex]\displaystyle \large{x^2-9=(x^2)-(3)^2}\\\displaystyle \large{x^2-9=(x-3)(x+3)}[/tex]

Therefore, the factored expression is:—

[tex]\displaystyle \large{\boxed{(x-3)(x+3)}}[/tex]

A scientist mixes water (containing no salt) with a solution that contains 20% salt. She wants to obtain 140 ounces of a mixture that is 5% salt. How many ounces of water and how many ounces of the 20% salt solution should she use?

Answers

Let x represent ounces of water.
Ounces of 30% salt solution required = 140 - x

(Percentage of salt solution)(ounces of 30% solution required) = (5% salt solution needed)(extra salt solution needed)

(20/100)(140-x) = (5/100)*140
(1/5)(140-x) = (1/20)*140
28-1/5x = 7
Multiply both sides of the equation by 5 to isolate x:
5*(28-1/5x = 7)*5
140-x = 35
-x = 35 - 140
-x = -105
x = 105

Ounces of salt solution = 140 - 105 = 35

Therefore, 105 ounces of water is required and 35 ounces of salt solution is required

so he have a total of 10 shares

next, we divide 50 by total shares to get what one share is

50 ÷ 10 = 5

5 is one share

fins what each is

for 3

3 shares so 3 fives

3 × 5 = 15

The average number of words in a romance novel is 64,436 and the standard deviation is 17,071. Assume the distribution is normal. Let X be the number of words in a randomly selected romance novel. Round all answers to 4 decimal places where possible.

a. What is the distribution of X? X ~ N(
64436
Correct,
17071
Correct)

b. Find the proportion of all novels that are between 72,972 and 90,043 words.


c. The 75th percentile for novels is
words. (Round to the nearest word)

d. The middle 60% of romance novels have from
words to
words. (Round to the nearest word)

Answers

b. You're looking for the probability

Pr [72,972 ≤ X ≤ 90,043]

Transform X to Z ∼ Normal(0, 1) using the rule

X = µ + σ Z

with µ = 64,436 and σ = 17,071. Then the probability is

Pr [(72,972 - µ)/σ ≤ (X - µ)/σ ≤ (90,043 - µ)/σ]

≈ Pr [0.5000 ≤ Z ≤ 1.5000]

You probably have a z-score table available, so you can look up the probabilities to be about

Pr [Z ≤ 0.5000] ≈ 0.6915

Pr [Z ≤ 1.5000] ≈ 0.9332

and then

Pr [0.5000 ≤ Z ≤ 1.5000] ≈ 0.9332 - 0.6915 = 0.2417

c. The 75th percentile word count that separates the lower 75% of the distribution from the upper 25%. In other words, its the count x such that

Pr [X ≤ x] = 0.75

Transforming to Z and looking up the z-score for 0.75, we have

Pr [(X - µ)/σ ≤ (x - µ)/σ] ≈ Pr [Z ≤ 0.6745]

so that

(x - µ)/σ ≈ 0.6745

x ≈ µ + 0.6745σ

x ≈ 75,950

d. Because the normal distribution is symmetric, the middle 60% of novels have word counts between µ - k and µ + k, where k is a constant such that

Pr [µ - k ≤ X ≤ µ + k] = 0.6

Also due to symmetry, we have

Pr [µ - k ≤ X ≤ µ + k] = 2 Pr [µ ≤ X ≤ µ + k]

⇒   Pr [µ ≤ X ≤ µ + k] = 0.3

Transform X to Z :

Pr [(µ - µ)/σ ≤ (X - µ)/σ ≤ (µ + k - µ)/σ] = 0.3

⇒   Pr [0 ≤ Z ≤ k/σ] = 0.3

⇒   Pr [Z ≤ k/σ] - Pr [Z ≤ 0] = 0.3

⇒   Pr [Z ≤ k/σ] - 0.5 = 0.3

⇒   Pr [Z ≤ k/σ] = 0.8

Consult a z-score table:

Pr [Z ≤ k/σ] ≈ Pr [Z ≤ 0.8416]

⇒   k/σ ≈ 0.8416

⇒   k ≈ 14,367

Then the middle 60% of novels have between µ - k = 50,069 and µ + k = 78,803 words.
