Lindsay and Justin want to collect data to find out the favorite after school activities of 7th grade students at East Middle School. Which group of people should Lindsay and Justin survey to achieve the most accurate results?.
Answer:
B
Step-by-step explanation:
This is so because, since precise information is required regarding a particular group of students (7th graders), it would be correct to target members of that group to obtain the first samples of information.
That is, by going to the most reliable source, a more reliable sample would be obtained.
. Mr. Donut wants to paint a donut on the wall of his restaurant. The diameter of the outside edge of the donut will be 22 inches. The area of the hole of the donut will be 78.5 square inches. How much area will need to be painted if only the donut needs to be painted? Use 3.14 for π.
Answer:
The area needed to be painted is approximately 301.44 square inches.
Step-by-step explanation:
The shape of a donut is represented by two concentrical circles, whose area is described by the following formula:
[tex]A =A_{g}-A_{s}[/tex] (Eq. 1)
Where:
[tex]A[/tex] - Total area of the donut, measured in squared inches.
[tex]A_{g}[/tex] - Area of the greater circle, measured in square inches.
[tex]A_{l}[/tex] - Area of the lesser circle, measured in square inches.
By using the definition of the area of the circle, we expand the equation above:
[tex]A = \frac{\pi}{4}\cdot D^{2}_{ext} - A_{s}[/tex] (Eq. 1b)
If we know that [tex]\pi = 3.14[/tex], [tex]D_{ext} = 22\,in[/tex] and [tex]A_{s} = 78.5\,in^{2}[/tex], the area needed to be painted is:
[tex]A = \frac{(3.14)\cdot (22\,in)^{2}}{4}-78.5\,in^{2}[/tex]
[tex]A \approx 301.44\,in^{2}[/tex]
The area needed to be painted is approximately 301.44 square inches.

Complete question:
At the beginning of the day the stock market goes down 30 3/4 points and stays at this level for most of the day. At the end of the day the stock market goes up 100 1/2 points from the low at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the day?
Answer:
The total change in the stock market is [tex]69\frac{3}{4}[/tex]
Step-by-step explanation:
Given;
the stock market at the beginning of the day = 30 3/4 points
the stock market at the end of the day = 100 1/2 points
The total change in the stock market from the beginning of the day to the end of the day is given by;
100 1/2 points - 30 3/4 points
[tex]= (100 -30) + (\frac{1}{2} -\frac{3}{4} )\\\\= 70 + (-\frac{1}{4} )\\\\= 70 - \frac{1}{4}\\\\= 69\frac{3}{4}[/tex]
Therefore, the total change in the stock market is [tex]69\frac{3}{4}[/tex]

You have 3 number
1, 9, and a missing number
The mean of the numbers is 4
work out the missing number
Answer:
2
Step-by-step explanation:
The last number is 2
You calculate this by the only way the mean can be 4 is if the 3 numbers= up to 12. so 9 + 1=10 and if were looking for 12 we need 2 more so 2.
10 + 2=12
When dealing with mean you calculate the sum of all the number(check) then divided by the total of numbers so 3
12 divided by 3=4 and 4= your mean

The data in the table can be modeled using an exponential function.
x | -1 | 0 | 1 | 2 | 3 |
y | 4 | 6 | 9 | 13.5 | 20.25 |
Based on the table, which function represents the same relationship?
A.) f(x) = 6 x 1.5^x
B.) f(x) = 0.67^x
C.) f(x) = 4 x 1.5^x
D.) f(x) = 6 x 0.67^x
Answer:
A
Step-by-step explanation:
You can plug in the x and y coordinates of the points to check which one is right.
The easiest point to start with is (0, 6).
[tex]A) 6=6*1.5^0\\B) 6=0.67^0\\C) 6=4*1.5^0\\D) 6=6*0.67^0[/tex]
Any number raised to the power of 0 is 1, so we can replace all of the exponents with 1.
[tex]A) 6=6\\B) 6=1\\C) 6=4\\D) 6=6[/tex]
That means we can immediately rule out B and C, since 6 clearly does not equal 1 or 4.
But since we still don't have our answer, we can plug in another point. Once again, you want to start with low, easy numbers, so let's plug in (1, 9).
[tex]A) 9=6*1.5^1\\D) 9=6*0.67^1[/tex]
Any number raised to the power of 1 is the same number:
[tex]A) 9=6*1.5\\D) 9=6*0.67[/tex]
Now we can multiply out both sides:
[tex]A) 9=9\\D)9=4[/tex]
Once again, it becomes immediately clear that D does not work, and A is therefore the correct equation.

Any help with this would be great, I'm not the best at these, and I'm behind from being sick and need to catch up.
Answer:
Step-by-step explanation:
Let say the following:
p = number of points
We know that they scored the same number of points in Game 1 and Game 2.
But in Game 3, they scored 6 points less than Game 1 and Game 2.
Therefore,
Game 1 = p
Game 2 = p
Game 3 = p - 6
To find the average you use the following formula:
Number of points / number of games = average
Basically,
(Game 1 + Game 2 + Game 3 ) / 3 = 63
So substitute the equations we made earlier and you get:
[tex]\frac{Game 1 + Game 2 + Game 3}{3} = 63\\\frac{p + p + (p - 6)}{3} = 63[/tex]
After this you just want to solve for "p"
Multiply both sides by 3 to get rid of the fraction:
p + p + (p - 6) = 63 x 3 = 189
3p - 6 = 189
Add 6 to both sides.
3p = 189 + 6 = 195
Divide both sides by 3
p = 195/3 = 65
So now we know p = 65 points. Substitute this back into our equations for each game:
Game 1 = p , Game 1 = 65 points
Game 2 = p , Game 2 = 65 points
Game 3 = p - 6 , Game 3 = 65 - 6 = 59 points

Solve for x in the literal equation −5 = xy + z.
Answer: x = -5 -z/y or x= -5/y - z/y
Step-by-step explanation:
-5 = xy + z -- then you need to isolate the x, so subtract z from both sides
-5-z = xy -- then divide both sides by y
x= -5-z/y

Carol gets paid $10 per hour to work as a lifeguard. This weekend, she worked on both Saturday and Sunday. She made a total of $80. Carol worked for 5 hours on Saturday. a For how many hours did she work on Sunday? Let x = hours spent working on Sunday. Choose the equation that represents this problem.
Answer:D
Step-by-step explanation: times the 10 by the amount of hours they did on saturday which is $50. Subtract $50 from the $80 the total and the answer is $30, divide 30 by 10 and thats 3 the amount of hours that they worked on sunday. 10(x+5)=80 x=3 (3+5)=8 10(8)=80
determine the quotient of 1/3/4 divided by 2/5
Answer:
First turn any mixed numbers into improper fractions. 1 3/4 would be 7/4. Becuase you multiply the whole number by the denominator and then add the numerator.
So now you have 7/4 divided by 2/5. Whenever you divide, you flip the 2nd fraction upside down... known as the reciprocal. And after that you multiply the first number by the upside down 2nd number.
So now you have 7/4 X 5/2. When multiplying, just multiply the numerators across and the denominators across. As your answer, you get 35/8 or 4 3/8.
Step-by-step explanation:
Answer:
35/8 or 4 3/8
Step-by-step explanation:
