Answer & Step-by-step explanation:

$K(5,4)$

Remember this:

$(x,y)$

$(5_{x},4_{y})$

When you are going to graph a point, you always start along the x-axis (the horizontal), then you move on to the y-axis (vertical). Both of the numbers in K are positive, so we will stay in Quadrant I.

For x, starting at (0,0) move to the right to point 5. From here, move up to the line that has value 4. Mark this spot with a dot and label if needed.

*If the x value is positive, you move to the right. If it is negative, you move to the left.

If the y value is positive, you move up. If it is negative, you move down.

Rob is saving to buy an MP3 player. For every 15 dollars he earns babysitting, he saves 6 dollars. On Saturday rob earned $75 do

zhenek [66]

Answer:

Rob saved $30 while he earned $75.

Step-by-step explanation:

Given:

For every 15 dollars he earns babysitting, he saves 6 dollars.

For money earned = $15

Money saved = $6

We will first find the percentage amount saved by rob

Percentage of amount is calculated by dividing money saved with for money saved and then multiplied by 100.

Percentage amount saved = $\frac{6}{15}\times100 =40\%$

Now we need to find the amount of money save when money earned $75.

Amount of money saved can be calculate by multiplying money earned with percentile amount saved.

Framing in equation form we get;

Amount saved = $\frac{40}{100}\times75 =\$30$

Hence Rob saved $30 while he earned $75.

Which equations represent the line that is parallel to 3x − 4y = 7 and passes through the point (−4, −2)? Select two options. y

andriy [413]

Answer:

Step-by-step explanation:

We want a line parallel to 3x − 4y = 7. Any such line will have an equation of the same form but a different constant.

If the new line is to pass through the point (-4, -2), replace x with -4 and y with -2. We obtain:

3(-4) − 4(-2) = -12 + 8 = -4. Thus, the desired new equation is 3x − 4y = -4.

This could also be written as 3x − 4y + 4 = 0. We could also solve this for y, obtaining:

3x + 4 = 4y, or y = (3/4)x + 1.

Consider random samples of size 50 from a population with proportion 0.15

WITCHER [35]

Answer:

a) Mean = 0.75

b) Standard error = 0.051

c) Yes

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 50

Sample proportion , p = 0.15

a) Mean

$\mu = np = 50(0.15) = 7.5$

b) Standard error

$S.E = \sqrt{\dfrac{p(1-p)}{n}} = \sqrt{\dfrac{0.15(1-0.15)}{50}} = 0.051$

c) Application of central limit theorem

Since the sample size is larger than 30, we cam apply central limit theorem for normal approximation.

To manage a rental property, a property manager charges $65 per month plus 6% of the rent.

Igoryamba

Given parameters:

Charge per month = $65

Percentage on rent= 6%

Amount paid by Jack per month = $164

Unknown:

Monthly rent on his property = ?

Solution:

Monthly rent on his property can be found by;

Amount paid by Jack per month = Charge per month + 6% of monthly rent

Let the monthly rent = x ;

So;

164 = 65 + $\frac{6}{100} x$ x

164 - 65 = $\frac{6x}{100}$

99 = $\frac{6x}{100}$

6x = 9900

x = 1650

Monthly rent on his property is $1650
