Answer:
The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35
Step-by-step explanation:
Given
Total length of one roll of ribbon = 9 feet
As the pieces have to be cut into inches, we will convert the measurement in feet to inches
As there are 12 inches in one feet, 9 feet will be equal to:
9*12 = 108 inches
Now first of all, we have to see how many 15 inches pieces can be cut from one role
So,
[tex]=\frac{Length\ of\ roll}{Length\ of\ piece}\\=\frac{108}{15}\\=7.2[/tex]
So the seamstress can cut 7 15-inch long pieces from a roll.
Now given that he has to cut from 5 rolls, the total number of 15-inch pieces will be:
[tex]= 5 * 7 =35[/tex]
Hence,
The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35
15) Miguel made $6,743 in February and $8,152 in March. Which is the best 4 estimate for the amount of money Miguel earned when rounding to the nearest hundred. *
Answer:
$14,900
Step-by-step explanation:
Given that,
Miguel made $6,743 in February and $8,152 in March.
We need to find the amount of money Miguel earned.
It is equal to the sum of amount made in February and March.
Sum = $6,743 + $8,152
= $14895
Nearest hundred :
Sum = $14,900
Hence, the total amount is $14,900.
a service station has 92-octane and 98-octane gasoline. How many liters of each should be mixed to provide 12 liters of 96-octane gasoline needed for chemical research
we use the rectangle rule
96-92=4 parts of 92 octane
98-96=2 parts of 98 octane
4x+2x=12
6x=12
x=2
4x=8 liters of 92 octane
2x=4 liters of 98 octane
A boy had 72 coins and lost 25% of them How muy coins

A researcher wants to be sure that the sample in her study is not unrepresentative of the distribution of ethnic groups in her community. Her sample includes 300 whites, 80 African Americans, 100 Latinos, 40 Asians, and 80 others. In her community, according to census records, there are 48% whites, 12% African Americans, 18% Latinos, 9% Asians, and 13% others. Is her sample unrepresentative of the population in her community
Answer:
Yes. Her sample is unrepresentative of the population in her community.
Step-by-step explanation:
a) Data and Calculations:
Population Study Census % Representative Over/Under
Sample Sample Representation
Whites 300 48% 288 (48% * 600) 12
African Americans 80 12% 72 (12% * 600) 8
Latinos 100 18% 108 (18% * 600) (8)
Asians 40 9% 54 (9% * 600) (14)
Others 80 13% 78 (13% * 600) 2
Total 600 100% 600 0
b) There is selection bias in her sample. A representative sample of 600 is the subset of a population that seeks to accurately reflect the characteristics of the larger group. When the sample for each category does not accurately represent the characteristics or attributes of the population categories, then it is unrepresentative.
Sampling is the collection of randomly chosen data from the entire population to come to an end conclusion about the variable to be determined or known.
Yes, the sample is unrepresentative of the entire population.
The reason for the sample being unrepresentative of the entire population in her community is that the selected sample is deviating a lot from the population count.
As per the computation, there is selection bias in her sample. This is because the representative sample is 600 that represents the entire population and reflects the characteristics of the larger group.
The sample becomes unrepresentative when the sample chosen does not accurately represent the true attributes of the population.

1.Plastic plates come in packs of 8, plastic utensils come in packs of 12, and plastic cups come in packs of 20. What are the least numbers of packs you should buy in order to have the same number of plates, utensils, and cups?
Answer:
Least no of packs = 120
Step-by-step explanation:
Given that,
Plastic plates come in packs of 8, plastic utensils come in packs of 12, and plastic cups come in packs of 20.
We need to find least numbers of packs you should buy in order to have the same number of plates, utensils, and cups.
It means we need to find the LCM of 8,12,20
Prime factorisation of 8 = 2×2×2
Prime factorisation of 12 = 2×3×2
Prime factorisation of 20=2×5×2
LCM = 120
Hence, there are 120 least number of packs you should buy in order to have the same number of plates, utensils, and cups

An emergency medical technician earns $19.71 per hour. One month she earns a gross pay of $3326.06. How much did she make per week if it was a 4.5 - week month? Round off the answer to two decimal places also. How much did she make per week if it was a 4.5 - week month? Round off the answer to two decimal places.
Answer:
The emergency medical technician made $739.12 per week
Step-by-step explanation:
Given that:
Per hour pay = $19.71
One month earning of emergency medical technician = $3326.06
Weeks in the following month = 4.5
For per week income, we will divide the monthly salary by number of weeks in the month.
Per week income = [tex]\frac{3326.06}{4.5}[/tex]
Per week income = $739.12
Hence,
The emergency medical technician made $739.12 per week

Hey there!
The formula to this equation is: y2 - y1 /x2 - x1
• y2 = -8
• y1 = 4
• x2 = 5
• x1 = 3
EQUATION:
