Answer:
There were 39 children at the party
Step-by-step explanation:
Here, we want to know the number of children at the party
To do this, we have to add the y-values ( frequencies of the age grades)
We have this as;
8 + 8 + 7 +10 + 6 = 39
I'ts 5x, 5x and then x = 1 is 2 and then y = e equals 3 and then 2x + 3 = 5x
Answer:
yes. The cost of the insurance is less than the probability cost of the operation
Step-by-step explanation:
yes. The cost of the insurance is less than the probability cost of the operation
The cost of health insurance = $1200
Cost of dramatic injury operation= $500,000
chances of need of operation= 47.3% over a 20 years period
the amount of pay insurance after 20 years= 
probable of cost operation= 0.473*500,00= $236,500
clearly the cost of insurance is less than the probable cost of operation.
Answer: 1.3125 gallons
Step-by-step explanation: The machine pumps 2.1 gallons of water every 1.6 minutes. 1.6 minutes is 1.6x more than 1 minute. So, we have to divide 1.6 by 1.6. Next, we have to divide 2.1 by 1.6. We can make this a bit easier by multiplying both of them by 10 to get 21/16 which is 1.3125.
Answer:
What are you asking? If you're asking for the area of the prism, it's <em>774in²</em>.
Step-by-step explanation:
First you need to use this formula.
2(wl + hl + hw)
w = width
l = length
h = height
Since we already know what all of those values are, we don't need to do any solving for them.
In this case:
width = 9
length = 9
height = 17
Plug those numbers into the formula and solve.
2(9 × 9 + 17 × 9 + 17 × 9)
It would be easiest to multiply the numbers before doing your adding.
2(81 + 153 + 153)
Add.
2(387)
Multiply what is in the parenthesis with the number on the outside, 2.
There's your answer, <em><u>774</u></em>.
Since this is area, you have to specify the type of measuring you're using (example: inches, feet, yards) and you have to be sure to include the ² after the measurement you're using because you may get points off for that.
<u>774in²</u>
