Some teenagers collected trash for a beach cleanup. The data for the number of pounds of trash collected by each teenager are shown below. 26, 26, 21, 22, 20, 25, 35 What is the standard deviation of the data? 0 pounds 4.66 pounds 5.03 pounds 25.33 pounds
Answers
Answer:
4.66
Step-by-step explanation:
We are given the following data
26, 26, 21, 22, 20, 25, 35
Step 1
We find the Mean
Mean = 26+ 26+ 21+ 22+20+25+ 35/7
= 175/7
= 25
Step 2
We find the Standard Deviation
The formula for Standard deviation that we would use is the Population Standard deviation, this is because the data given above is the data of the number of pounds of trash collected by each teenager
= √(x - Mean)²/n
= √(26 - 25)²+( 26 - 25)²+ (21 - 25)²+ (22 - 25)² +(20 - 25)²+(25 - 25)²+ (35 - 25)²/7
= √152/7
= √21.7142857
= 4.65985898
Approximately = 4.66
Answer:
5.03 Pounds (C)

The person above me is right, but you gotta solve for sample data; not population.
!This is for standard deviation!

Terry bought a sweater for$24 before tax he had a coupon for 1/4 off the sales tax rate was 6%. How much did terry pay for the sweater, including tax?
Answers
Answer: Terry paid $18.36 for the sweater.
Step-by-step explanation:
Given: Sales price of sweater = $24
Coupon states [tex]\dfrac14[/tex] off the sales, i.e. Terry will get [tex]\dfrac14\times24=\$6[/tex] discount.
Also, tax rate = 6%
Tax will be charged = 6% of Sales price of sweater
= 0.06 x 6
= $0.36
Now , Final amount for Terry = Sales price - discount +tax
= $(24-6+0.36)= $18.36
Hence, Terry paid $18.36 for the sweater.

Answer:
x = 8°, y = 28°
Angles are 64° and 116°
Step-by-step explanation:
Parallelogram
Opposite angles of a parallelogram are congruent, that is, they have the same measure, thus:
4y = y + 87
8x = 7x + 8
These are two separate equations that can be solved independently.
Subtracting y to the first equation:
3y = 87
Dividing by 3:
y = 87/3 = 29
y = 29°
Subtracting 7x to the second equation:
x = 8°
The internal angles of the parallelogram are:
8x = 64°
4y = 116°
The question doesn't have any specific requirements, so I solved the variables and calculated the angles.

Madison and Tanisha went out to lunch. The bill came to $18.94. Madison knows that her lunch cost 9.72. How much did Tanisha's lunch cost?
Answers
Answer:
Tanisha's lunch cost $9.22.
Step-by-step explanation:
Given that,
Total bill = $18.94
Cost for Madison cost = $9.72
Total cost = Tanisha's lunch + Madison's lunch
18.94 = Tanisha's lunch + 9.72
Tanisha's lunch = 18.94 - 9.72
Tanisha's lunch = 9.22
So, Tanisha's lunch cost $9.22.

the answer is -196 im sorry if i got it wrong
Step-by-step explanation:
Answer:
w = ~ - 32.7
Step-by-step explanation:
w6 + 58 = -138
Subtract 58 on both sides
w6 + 58 - 58 = -138 - 58
w6 = -196
Divide by 6 on both sides to isolate the variable
w6/6 = -196/6
w = - 32.66666666666667
w = ~ - 32.7

The diameter of a tire is 2.5 ft. Use this measurement to answer parts a and b. Show all work to receive full credit. A. Find the circumference of the tire.
B. About how many times will the tire have to rotate to travel 1 mile? (1 mile = 5,280 ft)
Answers
Answer:
A. The circumference of the tire is approximately 7.854 feet.
B. The tire rotates about 672 times to travel 1 mile.
Step-by-step explanation:
A. The circunference ([tex]s[/tex]), measured in feet, in terms of diameters is defined by the following formula:
[tex]s = \pi \cdot D[/tex] (1)
Where [tex]D[/tex] is the diameter of the tire, measured in feet.
If we know that [tex]D = 2.5\,ft[/tex], then the circunference of the tire is:
[tex]s = \pi\cdot (2.5\,ft)[/tex]
[tex]s \approx 7.854\,ft[/tex]
The circumference of the tire is approximately 7.854 feet.
B. The value found in A. represents the distance travelled by the tire per revolution. Then, the number of revolutions ([tex]n[/tex]), no unit, associated to the distance travelled is calculated by this expression:
[tex]n = \frac{s}{\pi\cdot D}[/tex] (2)
If we know that [tex]s = 5280\,ft[/tex] and [tex]D = 2.5\,ft[/tex], then the number of revolutions done by the tire to travel 1 mile is:
[tex]n = \frac{5280\,ft}{\pi\cdot (2.5\,ft)}[/tex]
[tex]n \approx 672.270[/tex]
The tire rotates about 672 times to travel 1 mile.
