Step-by-step explanation:
The size your dog and the number of times you take it to the vet, The amount your drive to school and the amount you have to pay for gas, The number of people at your party and the number of sodas you have in the refrigerator. What correlation are all of these. None, Positive, or Negative thanks so much.
1. No correlation
Those things don't really relate to each other.
2. Positive correlation
The higher the amount you drive your car, the more you'll have to pay for gas.
3. Negative correlation
More people = less soda.
(a) An angle measures 86. What is the measure of its supplement?
(b) An angle measures 34. What is the measure of its complement?
Answer:
a) 94
b) 56
Step-by-step explanation:
a)
Supplement means it adds up to 180 so:
180 - 86 = 94
b)
Complement means it adds up to 90 so:
90 - 34 = 56
A news article estimated that only 5% of those age 65 and older who prefer to watch the news, rather than to read or listen, watch the news online. This estimate was based on a survey of a large sample of adult Americans. Consider the population consisting of all adult Americans age 65 and older who prefer to watch the news, and suppose that for this population the actual proportion who prefer to watch online is 0.05. A random sample of n = 100 people will be selected from this population and p, the proportion of people who prefer to watch online, will be calculated.
(a) What are the mean and standard deviation of the sampling distribution of p? (Round your standard deviation to four decimal places.)
(b) Is the sampling distribution of p approximately normal for random samples of size n 100? Explain.
i. The sampling distribution of p is approximately normal because np is less than 10.
ii. The sampling distribution of p is approximately normal because np is at least 10.
iii. The sampling distribution of p is not approximately normal because np is less than 10
iv. The sampling distribution of p is not approximately normal because np is at least 10
v. The sampling distribution of p is not approximately normal because n(1 - p) is less than 10.
Answer:
a) The mean is 0.05 and the standard deviation is 0.0218.
b) v. The sampling distribution of p is not approximately normal because n(1 - p) is less than 10.
Step-by-step explanation:
Central Limit Theorem
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex].
If [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex], the sampling distribution of the sample proportion p will be approximately normal.
Consider the population consisting of all adult Americans age 65 and older who prefer to watch the news, and suppose that for this population the actual proportion who prefer to watch online is 0.05.
This means that [tex]p = 0.05[/tex]
A random sample of n = 100 people
So [tex]n = 100[/tex]
(a) What are the mean and standard deviation of the sampling distribution of p?
Mean [tex]\mu = p = 0.05[/tex]
Standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.05*0.95}{100}} = 0.0218[/tex]
The mean is 0.05 and the standard deviation is 0.0218.
(b) Is the sampling distribution of p approximately normal for random samples of size n 100? Explain.
[tex]np = 100*0.95 = 95 > 10[/tex]
[tex]n(1-p) = 100*0.05 = 5 < 10[/tex]
As n(1-p) < 10, it is not approximately normal, option v.
What is the least common multiple of 19 and 43?

Step-by-step explanation:
A farmer plants 987 apple trees in 9 rows. Can each row have the same number of trees? How do you know?
Each row cannot have the same number of trees.
What is Divisibility?In mathematics, the term "divisibility" describes a number's ability to be divided by another number in an equal amount without any residue. For instance, it's simple to understand how 40 by 4 can be divided. A huge piece of land that can be divided into smaller chunks and sold separately is said to be divisible, much as it is obvious when you cut into a pan of brownies and distribute equal amounts to each of your friends.
As per the given data:
Number of apple trees = 987
Number of rows = 9
To find whether each row has the same number of trees:
If 987 is divisible by 9 then, the same number of trees can be there else not.
= (987/9) = (329/3) = 109.667
Not divisible, so same number of trees cannot be there.
Hence, each row cannot have the same number of trees.

Step-by-step explanation:
Mr. Williams trains a group of student athletes. He wants to know how they are improving in the number of push-ups they can do.
These dot plots show the number of push-ups each student was able to do last month and this month.
How much did the mean number of push-ups increase from last month to this month?
Question 1 options:
2.75 more push-ups
4.375 more push-ups
7.5 more push-ups
There is not enough information given to answer the question.
Answer:
7.5 more push-ups
Step-by-step explanation:
From the dot plot attached :
Last month mean :
Σfx/Σf
Σfx = [(10*2)+(15*2)+(25*3)+(35*1)] = 160
Σf = (2 + 2 + 3 + 1) = 8
Mean = 160 / 8 = 20
This month mean :
Σfx/Σf
Σfx = [(10*1)+(15*1)+(25*1)+(30*3)+(40*2)] = 220
Σf = (1 + 1 + 1 + 3 + 2) = 8
Mean = 220/8
Mean = 27.5
Difference in mean :
This month mean - Last month mean
27.5 - 20
= 7.5

In the relationship between hours driven and distance traveled is y = 45x, which of the following ordered pairs would be graphed on the line that represents the relationship?
Step-by-step explanation:
(0,0) (1,45) (2,90) (3, 135) (4, 180) etc, etc
Answer:
(4, 180)
Step-by-step explanation:
Choices: (3,5), (4,60), (4,180), (5,9)
y = 45x
The value of y is 45 times the value of x.
The only point in which that is true is (4, 180) since 45 * 4 = 180.
Answer: (4, 180)
What is the value of x???
Answer:
22.5
Step-by-step explanation:
22.5 x 3 = 67.5
67.5 + 22.5 = 90
Graph the line with the equation y = 1/2 x + 5
Find two points and draw a line through them
y = 1/2(2) + 5
y = 1 + 5, 6
One point is (2,6)
y = 1/2(0) + 5
y = 5
Second point is (0,5)
I inserted a graph on desmos for example
Step-by-step explanation:
Rewrite in slope-intercept form.
[tex]y = \frac{1}{2} x + 5[/tex]
Use the slope-intercept form to find the slope and y-intercept.
Slope is : 1/2
y-intercept: (0,5)
Any line can be graphed using two points. Select two x values, and plug them into the equation in order to find the corresponding y values.

a circle centered ar the the orgin has a radius of 1/2 what is the equation of the circle
Answer:
The equation of the circle is [tex]x^2 + y^2 = \frac{1}{4}[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle with center [tex](x_0,y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
Centered at the the origin
Center (0,0), which means that [tex]x_0 = 0, y_0 = 0[/tex]
radius of 1/2
This means that [tex]r = \frac{1}{2}[/tex]
Equation:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
[tex](x - 0)^2 + (y - 0)^2 = (\frac{1}{2})^2[/tex]
[tex]x^2 + y^2 = \frac{1}{4}[/tex]
The equation of the circle is [tex]x^2 + y^2 = \frac{1}{4}[/tex]

Given the function f(x) = 4x3 + 13x, what is the gradient of the function when x = 2 ?
Answer:
y=45x+115
Step-by-step explanation:
We can find the slope of a line tangent to a curve at a point by evaluating the derivative of the function at that point.
We are given the function
f ( x ) = 4 x 3 + 12 x 2 + 9 x + 7
= f ( x ) = 4 x 3 + 12 x 2 + 9 x 1 + 7 x 0
Using the power rule, let's now compute the derivative of f( x )
f ' ( x ) = ( 3 ⋅ 4 x 2 ) + ( 2 ⋅ 12 x ) + ( 1 ⋅ 9 x 0 ) + 0 ⋅ 7 x − 1
f ' ( x ) = 12 x 2 + 24 x + 9
We can now find the slope of f ( x ) at x = − 3 by substituting this value into f ' ( x )
f ' ( − 3 ) = 12 ( − 3 ) 2 + 24 ( − 3 ) + 9
f'(-3)=12(9)+24(-3)+9
f'(-3)=108-72+9
f'(-3)=45(slope of the tangent line at x = − 3
Now that we have a slope for the tangent line, we need to identify a point on the line.
We know the tangent line touches the function f ( x ) at the point x = − 3 , so let's find the value of f ( x ) at this point:
f(-3)=4(-3)3+12(-3)2+9(-3)+7
f(-3)=4(-27)+12(9)+9(-3)+7
f(-3)=108+108-27+7
f'(-3)=-20
So we know the tangent line goes through the point
(-3,-20)
Finally, we can use the point-slope formula for a line to find the equation of the tangent line.
y=mx+b
To find the value of b , substitute the values we have calculated for the point and slope of the tangent line:
(-20)=(45)(-3)+b
-20=-135+b
b=115
So our final answer for the equation of the tangent line is:
y=45x+115
