Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

To find the distance between the line which formed like :

[tex]ax + by + c = 0[/tex]

and the point which is like :

[tex]h = \binom{m}{n} \\ [/tex]

we use following equation :

[tex]d = \frac{ |a(m) + b(n) + c| }{ \sqrt{ {a}^{2} + {b}^{2} } } \\ [/tex]

_________________________________ Step (2)

[tex]y = - x + 4[/tex]

[tex]x + y - 4 = 0[/tex]

So ;

[tex]a = 1[/tex]

[tex]b = 1[/tex]

[tex]c = - 4[/tex]

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

A = ( 2 , - 1 )

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

So we have :

[tex]d = \frac{ | \: 1(2) + 1( - 1) - 4| }{ \sqrt{ {1}^{2} + {1}^{2} } } = \\ [/tex]

[tex]d = \frac{ |2 - 1 - 4| }{ \sqrt{1 + 1} } = \frac{ | - 3| }{ \sqrt{2} } \\ [/tex]

[tex]d = \frac{3}{ \sqrt{2} } \\ [/tex]

And we're done.

Thanks for watching buddy good luck.

Since she earns $180 in 18 hours, she earns a rate of $ 180/18 per hour, which is $10 per hour.

In 30 hours she earns 30 times 10 dollars, which is 300 dollars.

You could also set up a proportion saying that 180/18 = x/30, then cross multiply to get 18x = 5400, and divide by 18 on both sides to get 300.

Answer:

Mabel will earn 300$ in 30 hours

Step-by-step explanation:

I took 180 and divided it by 18 so that I can find how much money she earns per hour.

180÷18= 10

10 × 30= 300

Answer:

65°

Step-by-step explanation:

35° + 80° + x° = 180°

115° + x = 180°

x = 180° - 115°

x = 65°

Answer:

The length is 25.3 yards, while the width is 12.7 yards.

Step-by-step explanation:

Perimeter of a rectangle, P = 2(l + w)

where l is its length and w the width.

Given that:

perimeter = 76 yards

It is twice as long as its wide, length = 2w

width = w

Then,

P = 2(l + w)

76 = 2(2w + w)

divide through by 2, to have;

38 = 2w + w

38 = 3w

⇒ w = 12.67 yards

Thus,

length = 2w = 2 x 12.67 = 25.34 yards

The length is 25.3 yards, while the width is 12.7 yards.

Answer:

2.5y=amount spent on drinks

Step-by-step explanation:

If chips are $2 and drinks are $2.50 and we do not know how many he bought of each, we put this into an equation which is

2x+2.5y

x=number of bags of chips while the 2 is two dollars per bag

so, if he bought 2 bags of chips 2(2)= $4 spent.

y= number of drinks and 2.5 is $2.5 per drink, so if he bought 4 drinks:

2.5(4)= $10 spent on drinks.

Answer: No, its not always true

It is possible to have a parallel line form, but you could easily have the new line intersect the old one. It depends on how you place the points.

Side note: Parallel lines have equal slopes but different y intercepts.

Answer: in the case of rolling a die the event of getting an 'odd-face' and the event of getting 'less than 4' are not mutually exclusive and they are also known as compatible event. The event of getting an 'odd-face' and the event of getting 'less than 4' occur when we get either 1 or 3.

Answer:

a)The average salary, then, for accountants in Canada is $2352

b) The standard deviation of the salary, then, for accountants in Portugal is $388.2

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ,

where:

x is the raw score

μ is the population mean

σ is the population standard deviation.

a) Suppose you are told that an accountant in Canada who makes $2,646.00 has a z-score of +0.50 relative to other accountants in Canada and that the standard deviation of the salary of accountants in Canada is $588.00. The average salary, then, for accountants in Canada is _____.

z = (x-μ)/σ

z = 0.50, x =$2,646.00 μ = ?? σ = $588

Hence,

0.50 = 2,646 - μ/588

0.50 × 588 = 2,646 - μ

294 = 2,646 - μ

μ = 2,646 - 294

μ = $2352

Therefore, the average salary, then, for accountants in Canada is $2352

b) Suppose you are also told that an accountant in Portugal who makes $2, 329.40 has a z-score of +2.00 relative to other accountants in Portugal and that the mean of the salary of accountants in Portugal is $1, 553. The standard deviation of the salary, then, for accountants in Portugal is _____ .

z = (x-μ)/σ

z = 2, x = $2,329.40 μ =$1,553 σ = ?

2 = ($2,329.40 - $1,553)/σ

2σ = $2,329.40 - $1,553

σ = $2,329.40 - $1,553/2

σ = $776.4 /2

σ = $388.2

Therefore, the standard deviation of the salary, then, for accountants in Portugal is $388.2

Answer:

The value of n would be 5

Step-by-step explanation:

This is understanding how to take numbers and writing them in scientific notation.

125,000 = 1.25 x 10⁵

First of all.

125,000 = 125,000.0  (See that decimal point?)

We want that decimal point behind the number 1 as seen in the scientific notation. All you have to do is move that decimal point to the left until you reach the ones place.

125000.  → 1.25

(You're not finished yet)

Since we moved the decimal five times, then we must put an exponential value of 5 above the 10

In conclusion:

125,000 = 1.25 x 10⁵

Answer:

(a) The difference between Kate's IQ and the mean is 21

(b) The z score is 1.4

Step-by-step explanation:

Here is the complete question:

IQ scores have a mean of 100 and a standard deviation of 15. Kate has an IQ of 121. (a) What is the difference between Kate's IQ and the mean (b) Convert Kate's IQ score to a z score.

Step-by-step explanation:

(a) To determine the difference between Kate's IQ and the mean, this can be done by subtracting the mean from Kate's IQ.

Mean = 100

Kate's IQ = 121

Difference between Kate's IQ and the mean = 121 - 100 = 21

Hence, the difference between Kate's IQ and the mean is 21.

(b) To convert Kate's IQ score to a z score,

z score is given by the formula

[tex]z =\frac{x - \mu}{\sigma}[/tex]

Where [tex]x[/tex] is the score

[tex]\mu[/tex] is the mean

and [tex]\sigma[/tex] is the standard deviation

From the question,

[tex]x[/tex] = 121

[tex]\mu[/tex] = 100

[tex]\sigma[/tex] = 15

Then, the z score is

[tex]z =\frac{x - \mu}{\sigma}[/tex]

[tex]z =\frac{121 - 100}{15}[/tex]

[tex]z =\frac{21}{15}[/tex]

[tex]z =\frac{7}{5}[/tex]

z = 1.4

Hence, the z score is 1.4.

Answer:

t(32) = 94

Step-by-step explanation:

a. I think s is the independent variable

b I think t or t(s) is the dependent variable since the total amount of money depends on how many treats are sold.

t(32) = 30 + 2(32)

t(32) = 30 + 64

t(32) = 94

I'm a little unsure on the dependent and independent variable but I know the function is correct.

Hope this helps :)

Answer:

10

Step-by-step explanation:

Answer:

Since the numbers are missing, I looked for a similar question:

Mr. Jones has $9000 to invest in three types of stocks: low-risk, medium-risk and high-risk. He invests according to the following rules: the amount invested in low-risk stocks will be at most $1000 more than the amount invested in medium-risk stocks. At least $7000 will be invested in a combination of low- and medium-risk stocks. No more than $7000 will be invested in a combination of medium- and high-risk stocks. The expected annual returns are 6% for low-risk stocks, 7% for medium-risk stocks, and 8% for high-risk stocks. How much should he invest in each type of stock to maximize his total expected yield?

let:

L = low risk stocks

M = medium risk stocks

H = high risk stocks  

maximize 0.06L + 0.07M + 0.08H

L + M + H ≤ 9000

L ≥ M + 1000

L + M ≥ 7000

M + H ≤ 7000

using solver, the optimal solution = 4,000L + 3,000M + 2,000H , which yields a maximum profit = $610

Mr. Jones should invest $4,000 in low risk stocks, $3,000 in medium risk stocks and $2,000 in high risk stocks.
