Jill, an employee at Old Navy, budgets 18 of her yearly salary for clothing. Jill's total clothing bill for the year is $8,180.

Triss [41]

Answer: $ 45,444.44

Step-by-step explanation:

Given: Jill budgets 18% of her yearly salary for clothing.

His total clothing bill for the year is $8,180.

Let x= her yearly salary

Then according to the question , we have

18% of x = 8180

Convert 18% into decimal by dividing it by 100 , we get

0.18 x= 8180

Multiply both sides by 100

⇒ 18x = 818000

Divide both sides by 18 , we get

x= 45444.44

Hence, her yearly salary = $ 45,444.44

The ______________ probability of an outcome is obtained by dividing the frequency of occurrence of an event by the number of tr

Norma-Jean [14]

Answer:

Empirical probability

Step-by-step explanation:

Empirical probability is data collected from experiment and real-life situation.

The "empirical probability" of an outcome is obtained by dividing the frequency of occurrence of an event by the number of trails of the experiment.

$\Longrightarrow: \sf{P(E)=\dfrac{\text{number of times event occured}}{\text{number of trails}}$

Therefore, the correct answer is empirical probability.

I hope this helps you! Let me know if my answer is wrong or not.

On a coordinate plane, a line has points (negative 2, negative 4) and (4, 2). Point P is at (0, 4). Which points lie on the line

NikAS [45]

Answer:

the correct options are:

(–1, 3), (–2, 2) and (–5, –1)

Step-by-step explanation:

Given that a line passes through two points

A(-2, -4) and B(4, 2)

Another point P(0, 4)

To find:

Which points lie on the line that passes through P and is parallel to line AB ?

Solution:

First of all, let us the find the equation of the line which is parallel to AB and passes through point P.

Parallel lines have the same slope.

Slope of a line is given as:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m=\dfrac{2-(-4)}{4-(-2)} = 1$

Now, using slope intercept form ( $y = mx+c$ ) of a line, we can write the equation of line parallel to AB:

$y =(1)x+c \Rightarrow y = x+c$

Now, putting the point P(0,4) to find c:

$4 = 0 +c \Rightarrow c = 4$

So, the equation is $\bold{y=x+4}$

So, the coordinates given in the options which have value of y coordinate equal to 4 greater than x coordinate will be true.

So, the correct options are:

(–1, 3), (–2, 2) and (–5, –1)
