A 7/37 B 7/30 C 7/23 D 23/30
Answer:
B 7/30
Step-by-step explanation:
P (Purple) = 70 / 300 = 7/ 30
Answer:
B
Step-by-step explanation:
Purple-70/300=7/30
B. 65.84 inches
C. 66.55 inches
D. 69.36 inches
Answer:
B. 65.84
Step-by-step explanation:
You are given the armspan and a relation between that and height. Put the given value in the equation and solve for the unknown.
... 67.5 = 1.123x -6.443
... 73.943 = 1.123x
... 73.943/1.123 = x = 65.84
Riley's height is predicted to be 65.84 inches.

Round your answers to the nearest integer.
a. The computations will be easier to work if you view this problem in terms
of thousands of passengers. Represent each number in terms of thousands
of passengers.
b. What is the mean number of passengers for these five cruise lines? (Give
the full number.)
c. What is the range? (Give the full number.)
d. What is the standard deviation? (Give the full number.)
The numbers in thousands are: 4133, 2369, 1295, 928, 679. The mean is 1881 thousand passengers, the range is 3454 thousand passengers, and the standard deviation is approximately 1218 thousand passengers.
Part A: To represent each number in terms of thousands of passengers, we simplify them as follows: 4,133,000 is 4,133 thousands of passengers, 2,369,000 is 2,369 thousands, 1,295,000 is 1,295 thousands, 928,000 is 928 thousands, and 679,000 is 679 thousands.
Part B: To calculate the mean number of passengers, you would add up all the passenger numbers and then divide by the number of values (5 in this case). This adds up to 9,404,000 passengers or, in terms of thousands, 9,404. Divided by 5, this gives a mean of 1,880,800 passengers, or 1,881 thousands of passengers.
Part C: The range is calculated by subtracting the smallest number from the largest. In this case, that would be 4,133,000 - 679,000 = 3,454,000, which is also 3,454 thousands of passengers.
Part D: Calculating the standard deviation involves multiple steps. First, for each value, subtract the mean and square this result. Then, calculate the mean of these squared differences. Finally, take the square root of this mean. Doing so, the standard deviation is approximate 1,217,982 passengers, or 1,218 thousands of passengers.

Answer:
$9,577
Step-by-step explanation:
Given:
Estimated time for the job = 40 hours
Number of laborers = 2
Per hour laborers cost = $10
Number of masons = 6
Per hour mason cost = $21
Worth of material = $3337
Estimated Profit = $400
Now,
The total amount spent on laborers
= Number of laborers × total working hours × Cost per hour
= 2 × 40 × $10
= $800
The total amount spent on masons
= Number of masons × total working hours × Cost per hour
= 6 × 40 × $21
= $5040
Hence,
the total estimated cost for the job
The total amount spent on laborers $800
The total amount spent on masons $5,040
Worth of material $3,337
Estimated Profit $400
==========================================================
Total estimated cost $9,577
