Answer:
Nina is not correct because she divided by 4, whereas she should’ve divided by 5.
Step-by-step explanation:
To find the mean, we add and divide by however many numbers. In this case, 6 + 7 + 4 + 0 + 3 = 20. Now, we divide by 5, because there are 5 scores in the data. This is where she went wrong, as she divided by 4. Instead, she should’ve divided by 5. This would’ve given her a mean of 4.

Answer:
V = 235.5
or V = 18π
Step-by-step explanation:
V=πr^2h
Volume of a cylinder is (pi)(radius)(radius)(height)
V = (3.14)(3)(3)(2)
V = 56.52
Or, since it said you can leave it as pi,
V = 18π

answers are
60m cubed
360m cubed
1130m cubed
2260m cubed
Answer:
≈ 1130 m³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the radius and h the height )
Here r = 6 and h = 10 , then
V = π × 6² × 10 = π × 36 × 10 = 360π ≈ 1130 m³

Consider the quadratic equation x^2 +7x+8=0. Which of the following is the correct form after substituting a, b, and c into the
Quadratic Formula?
Answer:
ax²+bx+c=0
Being the standard formula
Step-by-step explanation:
By direct substitution
a=1
b=7
c=8
If the quadratic equation x² +7x+8=0 then the correct form after substituting a, b, and c into the Quadratic Formula is x=-7±√7²-4(1)(8)/2(1)
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The given quadratic equation is x² +7x+8=0.
The quadratic equation standard form is ax²+bx+c=0
When we compare both the equations
The value of a is 1, b is 7 and c is 8
x=-b±√b²-4ac/2a
x=-7±√7²-4(1)(8)/2(1)
=-7±√49-32/2
x=-7±√17/2
Hence, if the quadratic equation x² +7x+8=0 then the correct form after substituting a, b, and c into the Quadratic Formula is x=-7±√7²-4(1)(8)/2(1)

A shirt originally cost $41.10, but it is on sale for $36.99. What is the percentage decrease of the price of the shirt? If necessary, round to the nearest percent. A. 10% B. 90% C. 11% D. 8%
Answer:
10%
Step-by-step explanation:
The first step is to calculate the decrease
Original price= $41.10
New price= $36.99
= 41.10-36.99
= 4.11
4.11/41.10 × 100
= 0.1×100
= 10%
Hence the percentage decrease is 10%

Write an equation of the line below
Answer:
y = 4/5x - 2
Step-by-step explanation:
To create an equation with just a line compare two points on the graph and see how far the x and y points are on the graph then put them into a fraction with y over x then find the y intercept or find where the x coordinate equals 0 in this case it was (0, -2). Now put it all together:
y = mx + b
mx = comparison of two points
b = y intercept

In circle R with QRS=90 and QR= 3 units find the length of arc QS round to the nearest hundredth
Hello, I Am BrotherEye
Answer:
27.92 units
Step-by-step explanation:
Radius (qr) = r = 16 units
<QŘS = θ = 82°
Length of an arc = (Θ / 360) * 2πr
L = (θ / 360) *2πr
L = (82 / 360) * 2π * 16
L = 0.2777 * 100.53
L = 27.917 units
L = 27.92 unit

What is the MODE of the data - (12, 8, 6, 12, 16, 12) *
help plsssss
Answer: Mode = 12
Explanation: The mode is the most frequent value, so it is the value that shows up the most. In this case, that would be the value "12" since it shows up three times (while the other values only show up once).
Answer:
12
Step-by-step explanation:
For future reference mode means MOST. So in this data, number 12 is repeated the most. That would mean the MODE is 12.
