Yuri and Nathan both made posters. Yuri made 1,272 copies of his poster. Nathan made 325 copies of his poster. How many more copies did Yuri make than Nathan?
Answer:
Yuri made 947 more copies than Nathan.
Step-by-step explanation:
Since we are finding the difference from the amount Yuri and Nathan made, the operation is subtraction. Since Yuri made more copies, his number will go first: 1272-325. Then, we solve by subtracting the two numbers, and you should get 947.
Thus, Yuri made 947 more copies than Nathan.

The water works commission needs to know the mean household usage of water by the residents of a small town in gallons per day. They would like the estimate to have a maximum error of 0.14 gallons. A previous study found that for an average family the variance is 1.69 gallons and the mean is 15.9 gallons per day. If they are using a 85% level of confidence, how large of a sample is required to estimate the mean usage of water? Round your answer up to the next integer.
Answer:
A sample of 179 is needed.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.85}{2} = 0.075[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.075 = 0.925[/tex], so Z = 1.44.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
A previous study found that for an average family the variance is 1.69 gallon?
This means that [tex]\sigma = \sqrt{1.69} = 1.3[/tex]
If they are using a 85% level of confidence, how large of a sample is required to estimate the mean usage of water?
A sample of n is needed, and n is found for M = 0.14. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]0.14 = 1.44\frac{1.3}{\sqrt{n}}[/tex]
[tex]0.14\sqrt{n} = 1.44*1.3[/tex]
[tex]\sqrt{n} = \frac{1.44*1.3}{0.14}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.44*1.3}{0.14})^2[/tex]
[tex]n = 178.8[/tex]
Rounding up
A sample of 179 is needed.

A SPINNER IS DIVIDED INTO EQUAL BLACK, WHITE, RED. YELLOW, AND GREEN
SECTIONS. IF I SPIN THE SPINNER 95 TIMES ABOUT HOW MANY TIMES WOULD IT LAND ON YELLOW
Answer:
We would expect to get yellow 19 times.
Step-by-step explanation:
The probability of getting yellow is 1/5 (It is one out of five options)
To find how many times it is probable to get yellow, multiply this probability by the number of trys: (1/5)(95)=19

Solve the equation 6 = p -8
Answer:
p = 14
Step-by-step explanation:
6 = p - 8
We want to isolate p, so add 8 to both sides.
6 + 8 = p
Add.
14 = p
Hope this helps!
Answer is: P = 14
Switch up the numbers.
6 = p - 8 → 6 + 8 = P
Solve for P.
6 + 8 = 14
Hence, 14 is the answer.

What is the value of 6(x + 15) - 12 when x = 12?
provided on your answer document.
Answer: 162
Step-by-step explanation:
6(12+15) Following the order of operations, (P.E.M.D.A.S), you should do parentheses first. So you add 12 and 15 to get 27. Were left with 6(27). So we multiply 6 and 27. The final answer is 162.

Ashley is buying items for her dog Lance. She buys a dog collar for $6.50 and wants to buy dog food at $4 a pound. If she wants to spend exactly $22.50, how many pounds of dog food can she afford? Which equation model this situation? *
1 point
4lbs : 6.50x + 22.50 = 4
5lbs : 4x + 6.50 = 22.50
4lbs : 4x + 6.50 = 22.50
4lbs : 4 + 6.50x = 22.50
Answer:
4 lbs : 4x + 6.50 = 22.50
Subtract 6.50 from 22.50 and divide the remaining number by 4.
a number line is divided into 8 equal parts to show eighths. A point is labeled 1/2. Name the equivalent fraction for the labeled point.
Answer:
4/8.
Step-by-step explanation:
4/8 is the correct answer for this question. This is why. If you take 8 and divide it in half, your answer will be 4. Also because fractions are division so the fraction 8/2 equals 4. This means the 1/2 mark is equal to 4.
P=(L+B), then B=_____?
Answer:
P = L+B
B = P-LHope it helps

Bill launched a model rocket, and estimated its height h, in feet, after 1 seconds. His results are shown in the table.
Time to 1 2 3 4
Height, h 0 110 190 240 255
Bill's data can be modeled by the function h(t) = -16t2 + 128t.
Which value is the best prediction for the height of the rocket after 5.5 seconds?
A. 150 ft
B. 180 ft
C. 220 ft
D. 250 ft
E 260 ft
Answer:
22ft
Step-by-step explanation:
Given the height of Bills modeled by the function h(t) = -16t^2 + 128t.
To get his height after 5.5secs, we will replace t with 5.5 a shown;
h(t) = -16t^2 + 128t.
h(5.5) = -16(5.5)^2 + 128(5.5)
h(5.5) = =-484+704
h(5.5) = 220ft
Hence his height after 5.5secs is 22ft
