Complete Question
A set of magical wand prices are normally distributed with a mean of 50 dollars and a standard deviation of 4 dollars. A blackthorn wand has a price of 45.20. What proportion of wand prices are lower than the price of the blackthorn wand? You may round your answer to four decimal places
Answer:
0.1151
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = $45.20
μ is the population mean = $50
σ is the population standard deviation = $4
We are solving for x < 45.20
Hence:
z = 45.20 - 50/4
z = -1.2
Probability value from Z-Table:
P(x<45.20) = 0.11507
Approximately to 4 decimal places = 0.1151
Therefore, the proportion of wand prices that are lower than the price of the blackthorn wand is 0.1151

Ashley has two jobs: mowing lawns and babysitting. She earns $10 per hour mowing lawns (x) and $8 per hour babysitting (y). And she wants to earn at least $160 per week. Rewrite the inequality from in slope-intercept form
Answer:
18x ≥ 160
Step-by-step explanation:
Ashley has two jobs: mowing lawns and babysitting. She earns $10 per hour mowing lawns (x) and $8 per hour babysitting (y). And she wants to earn at least $160 per week.
Let the number of hours = x
At least = Greater than or equal to
Slope intercept form
= y = mx + c
y = $160
Hence
10x + 8x ≥ 160
18x ≥ 160

convert 4 miles into cm. show your work
Answer:
643737.6
Step-by-step explanation:
1 inch is 2.54 centimeters. 2.54 centimeters is 1 inch. 12x2.54 =30.48. 30.48 is equal to one foot because 12 inches are in 1 foot and one inch is 2.54 centimeters. 1 yard is 3 feet so 30.48x3=91.44. 1 yard is equal to 91.44 centimeters. 1 miles is 1760 yards so 91.44x1760= 160934.4. 1 mile is equal to 160934.4 centimeters. Since 1 mile is equal to 160934.4 centimeters, you have to multiply 160934.4 by 4 to get 4 miles. 160934.4x4=643737.6 and this is your final answer. Therefore, 4 miles is equal to 643737.6 centimeters.

If 3 runners has a mean running time of 6.2, 7.4 and.6.9 and had an interquartile range of 1.1, .02 and .08 who would be the fastest runner
Answer:
The runner with a mean running time of 6.2
Step-by-step explanation:
The value range parameters of the three runners are;
The mean running time of the runner, A = 6.2
The mean running time of the runner, B = 7.4
The mean running time of the runner, C = 6.9
The interquartile range of the runner, A = 1.1
The interquartile range of the runner, B = 0.02
The interquartile range of the runner, C = 0.08
Whereby the number of running times for the 3 runners is large, and with the assumption that distribution of the mean is normal, we have
The mean = The mode of the data
Therefore, the minimum, and maximum running time of the runners are;
Runner A;
Minimum running time = 6.2 - 1.1 = 5.1
Maximum running time = 6.2 + 1.1 = 7.3
Runner B;
Minimum running time = 7.4 - 0.02 = 7.38
Maximum running time = 7.4 + 0.02 = 7.42
Runner C;
Minimum running time = 6.9 - 0.08 = 6.82
Maximum running time = 6.9 + 0.08 = 6.98
The fastest runner has the lowest running time;
Therefore, the fastest runner is runner A with a mean running time of 6.2 with a minimum running time of 5.1

20 divided by 2 1/3 = 8.57
8 batches is the answer.
Answer:
Actually, 20 divided by 2 1/3 equals 8.57 repeating (8.571428...), which can be rounded to 8.57 to two decimal places.
To see why, we can convert the mixed number 2 1/3 to an improper fraction:
2 1/3 = (2 * 3 + 1) / 3 = 7/3
Then, we can rewrite the division as a fraction and simplify:
20 / (7/3) = 20 * (3/7) = 60/7 = 8.571428...
So, 20 divided by 2 1/3 is approximately 8.57.

HOPE THIS HELPS!!Mary, Josephine, Quinn, Taylor, Max, and Taylor went out to lunch and the total bill was $72. Mary puts in $20 , and Josephine puts in $12. The rest of the group splits the bill equally. Which equation and solution represent the amount a that each of the remaining people pay?
Answer:
i. The equation required = [tex]\frac{remaining amount of the bill}{remaining number of people}[/tex]
ii. Remaining people would pay $10 each.
Step-by-step explanation:
Total number of people involved = 6
Total bill of their lunch = $72
Mary and Josephine paid = $20 + $12
= $32
The remaining bill to be paid = $72 - $32
= $40
The rest of the group = 4
Splitting the remaining bill equally,
the equation required = [tex]\frac{remaining amount of the bill}{remaining number of people}[/tex]
= ($40) ÷ 4
= $[tex]\frac{40}{4}[/tex]
= $10
The amount that each of the remaining people would pay is $10.
8 A right rectangular prism is completely filled with small cubes. Each small cube
has edges that are 1/4 in. long. The volume of the prism is 5 in.. How many cubes
does it take to fill the prism?
A-20
B-64
C-125
D-320
The number of cubes in the rectangle prism will be 320. Then the correct option is D.
What is the volume of the rectangular prism?Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as
V = L x W x H
A right rectangular prism is completely filled with small cubes. Each small cube has edges that are 1/4 inches long. The volume of the prism is 5 inches.
Let 'n' be the number of cubes. And all the sides of the cube are congruent. Then the volume of each cube is calculated as,
Volume of cube = (1/4) x (1/4) x (1/4)
Volume of cube = 1 / 64 cubic inches
The volume of the rectangle and the volume of small 'n' cubes will be equal. Then we have
Volume of 'n' cube = Volume of a rectangle
(1 / 64) n = 5
n = 5 x 64
n = 320
The number of cubes in the rectangle prism will be 320. Then the correct option is D.
