During a cold winter, the temperature stayed below zero for ten days (ranging from -20 to -5). The variance of the temperatures of the ten day period A. is negative since all the numbers are negative B. must be at least zero C. can not be computed since all the numbers are negative D. can be either negative or positive
Using the variance concept, it is found that the correct option is:
B. must be at least zero
The mean of a data-set is the sum of all observations divided by the number of observations.The variance of a data-set is the sum of the differences squared between each term and the mean, divided by the number of values.Since the variance is squared, it's minimum value is 0, and thus, the correct option is:
B. must be at least zero

Find volume
Step-by-step explanation:
The volume of cylinder = [tex]\pi r^{2}h[/tex]
The radius of cylinder = 20 ÷ 2 = 10
The volume of cylinder = [tex](\frac{22}{7})(10^{2} )(7)[/tex]
= [tex](22)(100)[/tex] = 2200
please give me a brainliest answer
Answer:
Volume of cylinder = 2,198 cmSolution:
volume of a cylinder = area of base(pi × radius²) × altitude (height)
Volume = πr² × altitude
V = 3.14 × 10² × 7
V = 3.14 × 100 × 7
V = 314 × 7
V = 2,198 cm

Why might you write the equation in
point-slope form instead of slope-intercept
form?
Step-by-step explanation:
Slope-intercept form is useful when we know the y- intercept of a line. However, we are not always given this information. When we know the slope and one point which is not the y-intercept, we can write the equation in point-slope form.
I hope this will help you out!
The equation of a line whose slope is 'm' and which passes through a point (x1, y1) is found using the point slope form.
We need to check why might we write the equation in point-slope form instead of slope-intercept form.
What is point-slope form?Point slope form is used to represent a straight line using its slope and a point on the line. That means, the equation of a line whose slope is 'm' and which passes through a point (x1, y1) is found using the point slope form. Different forms can be used to express the equation of a straight line. One of them is point slope form. The equation of the point slope form is: y - y1 = m(x - x1)
where, (x, y) is a random point on the line and m is the slope of the line.
The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as: y = mx + b.
We use point-slope form with one coordinate and slope.
Therefore, the equation of a line whose slope is 'm' and which passes through a point (x1, y1) is found using the point slope form.

Step-by-step explanation:
Correct on edge
The function will be one-to-one only if c = 13.
When a function is one-to-one?
A function is one-to-one if and only if each value in the range appears only once.
So, the given set will represent a one-to-one function if c takes a value that is not repeated in any of the other coordinate pairs.
We have:
(1, 2), (2, 3), (3, 5), (4, 7), (5, 11), (6, c)
For the given options, the only element that not already appears in one of the pairs is c = 13, so that is the correct option.

Answer: 135 degrees
Step-by-step explanation:
Answer:
135
Step-by-step explanation:
sum of triangle angles = 180
then JLK =. 180 -(70+65) = 180 - 135 = 45
then JLK = 45
since JLM = 180
then KLM = 180 - 45 = 135

if f(x)=3x-15 and g(x)=2x+11; find f(g(2))
Answer:
f(g(2)) = 30
Step-by-step explanation:
Evaluate g(2) , then substitute the value obtained into f(x)
g(2) = 2(2) + 11 = 4 + 11 = 15 , then
f(15) = 3(15) - 15 = 45 - 15 = 30
Step-by-step explanation:
[tex]f(x) = 3x - 15 \\ g(x) = 2x + 11 \\ f(g(x)) = 3(2x + 11) - 15 \\ f(g(x)) = 6x + 33 - 15 \\ f(g(x)) = 6x + 18 \\ f(g(2)) = 6(2) + 18 \\ f(g(2)) = 12 + 18 \\ \boxed{f(g(2)) = 30}[/tex]

A school gym is set up for an
assembly. There are 17 rows with 28
chairs in each row. Parents are sitting
in half the chairs, but the other half
are empty. How many chairs are empty?
Answer:
238 chairs are empty
Step-by-step explanation:
Firstly,
you'll have to times 17 by 28 to get the total chairs in the school gym
17 × 28
= 476
Next,
divide it by 2 because half of the gym???
476/2
= 238
So, the amount of the empty chairs in the school gym are 238 in total ｡◕‿◕｡
