[tex]Answer: y =\dfrac{1}{2}(x +2)^{2}+[/tex]Answer:

Step-by-step explanation:

Vertex form of quadratic function: y =a(x -h)² + k

Where (h,k) is the vertex

vertex (-2 , 6)

y = a(x -[-2])² + 6

y = a(x + 2)² + 6

This is passing through (-4,8)

8 = a(-4 + 2)² + 6

8 = a(-2)²+ 6

8  = 4a  +6

8 - 6 = 4a

4a = 2

a = 2/4

a = 1/2

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

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;

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

Answer:

5/9, 9/12, 6/7, 6/9 are the ones I believe so far

Step-by-step explanation:

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.

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

Answer:

(x-3)(x+3)

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:—

We have to find what one share is

we have 3 shares + 2 shares + 5 shares

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

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,

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]

Multiplying 16 by 5,

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

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

Answer:

377.36(2decimal places)

Step-by-step explanation:

Solution

First write down all known info about problem

Loss(L) percent:47%

Selling price(SP):200

Cost Price is unknown but CP percent equals 100%(basic percent b'cos it represents the basic cost of the item)

When at a loss, the CP is higher than the SP so subtract the L% from the CP% to get the SP percent...

∴SP% equals CP%-L%

100%-47%:53% ∴SP%:53%

We can simply cross multiply now by saying,

If 53% equals 200

∴100% equals a variable(x)

Cross multiplying,we get:

53x equals (200×100) so dividing both sides by 53,

x equals 377.36(2 decimal places)

Therefore, the CP is 377.36

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

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
