#2.) Shipment Times. A survey of 36 selected recording companies showed these numbers of days that it took to receive a shipment from the day it was ordered. Find the class mean and the modal class for the data.
Days / Frequency
1-3 6
4 - 6 8
7-9 10
10 - 12 7
13 - 15 0
16 - 18 5
Answer:
1. Mean => 8.2
2. Modal class => 7 - 9
Step-by-step explanation:
From the question given above, the following data were obtained:
Days >>>>>> Frequency
1 - 3 >>>>>>> 6
4 - 6 >>>>>> 8
7 - 9 >>>>>> 10
10 - 12 >>>>> 7
13 - 15 >>>>> 0
16 - 18 >>>>> 5
Next, we shall determine the the day mark.
The day mark is obtained by adding the the lower and upper class intervals and diving the result by 2.
This is illustrated below:
Days >> Day mark >>> Frequency
1 - 3 >>> 2 >>>>>>>>>> 6
4 - 6 >>> 5 >>>>>>>>> 8
7 - 9 >>> 8 >>>>>>>>> 10
10 - 12 >> 11 >>>>>>>> 7
13 - 15 >> 14 >>>>>>>> 0
16 - 18 >> 17 >>>>>>>> 5
1. Determination of the mean.
Summation of (day mark × frequency) = (2×6) + (5×8) + (8×10) + (11×7) + (14×0) +(17×5)
= 12 + 40 + 80 + 77 + 0 + 85
= 294
Summation of frequency = 6 + 8 + 10 + 7 + 0 + 5
= 36
Mean = Summation of (day mark × frequency) / Summation of frequency
Mean = 294 / 36
Mean = 8.2
2. Determination of the modal class.
The modal class is simply the class with the highest frequency.
Days >>>>>> Frequency
1 - 3 >>>>>>> 6
4 - 6 >>>>>> 8
7 - 9 >>>>>> 10
10 - 12 >>>>> 7
13 - 15 >>>>> 0
Considering the data given above, the class with the highest frequency is 7 - 9.
Thus, the modal class is => 7 - 9

The dimensions of a rectangular sandbox are 4x + 2 by 2x + 4. The dimensions of a rectangular garden are 3x - 2 by x + 4. Which
expression represents how much more area the sandbox covers than the garden?
O A 5x2 + 10x + 16
OB. 10x2 + 8
o C. 8x2 + 20x + 8
O D. 11x2 + 30x
Answer:
A. 5x²+10x+16
Step-by-step explanation:
Sandbox Dimensions - Garden Dimensions
(4x+2)(2x+4) - (3x-2)(x+4)
(8x²+20x+8) - (3x²+10x-8)
5x²+10x+16
Is 3.13 greater than 3.12
Answer:
yes
Step-by-step explanation:
if we figure out the difference between the two numbers by subtracting one from the other, if the product comes out positive, then the number you subtracted from is greater, if the product comes up negative, then the number you subtracted from is lesser
say we did 3.13 as our first number
3.13 - 3.12 = 0.01
this means that 3.13 is greater by 0.01, if we switch the two numbers however...
3.12 - 3.13 = -0.01
then that means that 3.12 is lesser by 0.01
i hope this makes sence, working with decimals may get tricky sometimes lol
Yes, 3.13 is greater than 3.12.
What is decimal?A decimal number is a number in which whole number part is separated from a decimal.
How to find greater number?We have been given two numbers 3.13 and 3.12 and we have to find the greater number from these two numbers. When two numbers are in decimal then firstly we have to see the digit before the decimal, the number having large digit becomes large. If the digit before decimal is same in both numbers then we have to see whether the first digit after the decimal is greater or not. If this digit is also same then we will move towards left and so on.
In the numbers 3.12 and 3.13, 3 which is second digit after decimal is greater than 2. So 3.13 is greater than 3.12.
Hence 3.13 is greater than 3.12.

Leo has purchased a fee-for-service health insurance plan from Leroux Health Insurance. Plan A includes a $225.00 monthly premium and an annual deductible of $5,500.00 (not including co-pays). Except for chronic back pain, Leo is a fairly healthy man. He visits his primary care physician four times a year on scheduled visits. He sees a chiropractic specialist every two weeks to help with his lower back pain. He has no current prescriptions that need refilling regularly. Assuming Leo maintains his regular visits with his primary care physician and his chiropractor, and avoids any trips to the emergency room or urgent care, how much will Leo pay in health care related fees this year, including his premium payments? See the table below: *

what offer is the best price per square inch pizza?
with a radius of 8 inches and a central angle of 45 for 3.75 or
difra offers a slice of pizza with a radius of 7 inches and a central angle of 65 for 4.75
Step-by-step explanation:
The area of a sector is given by :
[tex]A=\dfrac{\theta}{360}\times\pi r^2[/tex]
When r = 8 inches and [tex]\theta=45^{\circ}[/tex]
[tex]A=\dfrac{45}{360}\times \pi \times 8^2\\\\A=25.13\ in^2[/tex]
Now when r = 7 inches and [tex]\theta=65^{\circ}[/tex]
[tex]A=\dfrac{65}{360}\times \pi \times 7^2\\\\A=27.79\ in^2[/tex]
So, the best offer is given by difra i.e. a slice of pizza with a radius of 7 inches and a central angle of 65.

Answer:
4,8 and 16Let the three numbers be a,ar, ar^2 ,
where r is the common ratio.
⇒a+ar+ar^2 =28 and a^3 r^3 =512

Last week at the park Haeather ran 4 miles in 48 minutes when she runs her next race she Hope's to improve her time by 2 minutes per mile
Last week at the park what was haeather rate of speed in miles per hour
Answer:
Haeather ran at a speed of 5 miles per hour.
Step-by-step explanation:
Given that last week at the park Haeather ran 4 miles in 48 minutes, to determine what was Haeather rate of speed in miles per hour the following mathematical calculation must be performed:
48/4 = 12
Thus, Haeather ran 1 mile every 12 minutes.
60/12 = 5
1 x 5 = 5
Therefore, Haeather ran at a speed of 5 miles per hour.
