Answer:

$114.3

Step-by-step explanation:

Number of hours worked last week  = 12hrs

Amount earned for her work hours = $98

 The rate at which she earned =  ?

        Rate = \frac{amount earned }{total work hour}  

        Rate  = \frac{98}{12}    = $8.17/hr

Now;

Since the total hours she worked during the weekend  = 14hrs

  Amount earned  = $8.17/hr   x 14hrs   = $114.3

8. which of the following ordered pairs is a solution of the given system of linear equations
V125BC [204]

Answer:

Option D The solution of the system is the point (-3,5)

Step-by-step explanation:

we have

x+y=2 -----> equation A

y=-2x-1 ------> equation B

Solve the system by substitution

Substitute the equation B in equation A and solve for x

x+(-2x-1)=2

-x-1=2

x=-2-1

x=-3

Find the value of y

y=-2x-1

y=-2(-3)-1

y=5

therefore

The solution of the system is the point (-3,5)

The stemplot displays the selling prices of homes for ABC Realty in April.
Alexxandr [17]

The stemplot displays the entire values for the selling prices of homes for ABC Reality in April.

The correct set of data for the stemplot is the option;

  • <u>$459,000, $227,000, $67,000, $123,000, $213,000, $482,000, $85,000, $181,000, $225,000, $92,000, $181,000, $287,000, $196,000, $276,000</u>

<h3>Method by which the above option is selected</h3>

The data in the stemplot are;

459,000, 482,000, 213,000, 225,000, 276,000, 277,000, 287,000, 123,000, 181,000, 181,000, 196,000, 67,000, 85,000, 92,000

Given that there are no values in the 300,000s, and that 181,000 appear twice, the option that corresponds to the above data is therefore;

  • $459,000, $277,000, $67,000, $123,000, $213,000, $482,000, $85,000, $181,000, $225,000, $92,000, $181,000, $287,000, $196,000, $276,000

The capacity of an elevator is 12 people or 2088 pounds. the capacity will be exceeded if 12 people have weights with a mean gre
boyakko [2]

suppose the people have weights that are normally distributed with a mean of 177 lb and a standard deviation of 26 lb.

Find the probability that if a person is randomly selected, his weight will be greater than 174 pounds?

Assume that weights of people are normally distributed with a mean of 177 lb and a standard deviation of 26 lb.

Mean = 177

standard deviation = 26

We find z-score using given mean and standard deviation

z = \frac{x-mean}{standard deviation}

= \frac{174-177}{26}

=-0.11538

Probability (z>-0.11538) = 1 - 0.4562 (use normal distribution table)

= 0.5438

P(weight will be greater than 174 lb) = 0.5438

How can I find the volume of a cone 9 radius and 18 height​
Anastasy [175]

Answer:

V = 486\pi, or approx. 1,526.814

Step-by-step explanation:

V = \pi*r²*(h/3)

plug in the numbers: V = \pi * (9)² * (18/3)

simplify: V = \pi * 81 * 6

simplify: V = 486\pi, or approx. 1,526.814
