Answer:

[tex]\bold{K = 5n {}^{2} + w} [/tex]

Given ,

value of n = 4

value of w = - 6

Then ,

[tex]\bold{K = 5(4) {}^{2} + ( - 6)} \\\bold{ K = 5(16) - 6} \\\bold{ K = 80 - 6} \\ \fbox\pink{K = 74}[/tex]

hope helpful~

Answer:

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]

[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..!!

Step-by-step explanation:

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

for 2

2 shares so 2 fives

2 × 5 = 10

and for 5

can you work it out and leave in the comments i will say if it is correct

Solution:

The solution to the given system of equation is the intersection point created with the 2 lines. The solution must satisfy all equations. We can see the intersection. To identify the solution, plot the solution on the graph.

Option C is correct.

~Refer to image for plotted solution~

Formula for permutation is:

[tex] \boxed{ \tt^{n} C_{r} = \frac{n!}{r!(n - r)!} }[/tex]

Plug in the values:

Required number of ways = ²C7

[tex] \sf \frac{7 \times 6 \times \cancel{5!}}{ \cancel{5! }\times 2!} [/tex]

[tex] \sf \frac{7 \times 6 }{ 2!} [/tex]

[tex] \sf \frac{42 }{ 2!} [/tex]

[tex] \sf \frac{42 }{ 2} = 21[/tex]

Thus, The players can be selected in 21 different ways!!~

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

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:

The answer is 47.5 and 72.5

Step-by-step explanation:

So,

Let the number be x and the other number be (x + 25).

Now,

x + (x + 25) = 120

x + x + 25 = 120

2x + 25 = 120

2x + 25 – 25 = 120 – 25

2x = 95

2x/2 = 95/2

x = 47.5

Thus, The number be x is equal to 47.5 and other which is more 25 than other number is (47.5 + 25) = 72.5

-TheUnknownScientist 72

Answer:

The numbers are 47.5 and 72.5

Step-by-step explanation:

Let "x" represent the larger number, then the smaller number would be equivalent to:

[tex]x-25[/tex]

Larger Number + Smaller Number = 120

Therefore...

[tex]x+x-25=120[/tex]

Combine like terms:

[tex]2x-25=120[/tex]

Add 25 to both sides (note we are utilizing the Addition Property of Equality which essentially states that if you add a value to one side of the equation, you must add it to the other side as well):

[tex]2x=120+25\\2x=145[/tex]

Divide both sides by 2 (note we are now utilizing the Division Property of Equality which essentially states that if you divide a value from one side of the equation, you must divide it from the other side as well; the same as the Addition Property of Equality, but with division instead):

[tex]x=\frac{145}{2}\\x=72.5[/tex]

Therefore...

[tex]x-25=72.5-25=47.5[/tex]

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:—

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

Answer:

8%

Step-by-step explanation:

The original perimeter is 100cm

The 20cm is representative of the width

30cm is representative of the length

length is increased by 10%

30+(.10 x 30)

(1 + .10) × 30

(100% + 10%) × 30

110% × 30

110 ÷ 100 × 30

110 × 30 ÷ 100

3,300 ÷ 100

= 33

length is increased by 5%

20 + (5% × 20) =

20 + 5% × 20 =

(1 + 5%) × 20 =

(100% + 5%) × 20 =

105% × 20 =

105 ÷ 100 × 20 =

105 × 20 ÷ 100 =

2,100 ÷ 100 =

= 21

New perimeter: 108 cm

Percentage increase:

(108-100):100*100 =

(108:100-1)*100 =

108-100 = 8

= 8%

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

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
