We conduct a chi-square test with 6 degrees of freedom and find a test statistic of 20.32. The p-value for this test would be:
Answer: 0.002429
Step-by-step explanation:
Given that:
Degree of freedom = 6
Value of Chisquare test statistic = 20.32
The P value of the Chisquare distribution with a test statistic of 20.32 and a degree of freedom of 6 can be obtained using a Chisquare p value calculator.
P(20.32, 6), at 0.05 the degree of freedom obtained is :
0.002429
This p value shows that result is significant at p < 0.05.
As the P value obtained is lesser than the significance level.
= 0.002429
What is the slope
A. slope=1/3
B. slope= -3
C. slope = 3
Answer:
3
Step-by-step explanation:
slope = rise/run
Start at an easy to read point, such as (0, -2).
Go up 3 and right 1.
That is a rise of 3 and a run of 1.
slope = rise/run = 3/1 = 3
Answer: 3
Answer:
3
Step-by-step explanation:
Count how many points it goes up and then over to cross a square through the corner. In this case it goes up 3 over one. That simplifies to be just 3. Hope that made sense.
Factor this polynomial completely.
x2 - 6x + 9
O A. (x+3)(x + 3)
OB. (x+3)(x-3)
O C. Does not factor
O D. (x - 3)(x-3)
==========================================================
Explanation:
The last term is 9 and the middle coefficient is -6.
We need to find two numbers that multiply to the last term, and also add to the middle coefficient.
Through trial and error, you should find the two numbers -3 and -3
-3 plus -3 = -6
-3 times -3 = 9
Those two values directly lead to the factorization (x-3)(x-3)
We can FOIL out (x-3)(x-3) to get x^2-6x+9 to help confirm the answer. Distribution works as well. The box method is a visual way to do it also.

What is the equation of a line that is passing through the point (2, 11)
and is parallel to the line y = 4x – 5?
Answer:
y=4x+3
Step-by-step explanation:
since its parallel they have the same slope
y=mx+b
(11)=(4)(2)+b
11=8+b
then subtract 8 on both sides
11=8+b
-8=-8+b
3=b
then y=4x+3
Joe has 5 shirts, 3 pairs of pants and 4 pairs of shoes. He needs to make an outfit containing one of each item. How many different outfits are possible?
Answer:
60 outfits
Step-by-step explanation:
5 shirts x 3 pants x 4 shoes = 60 outfits (containing 1 shirt, 1 pant, 1 shoe)
This is pretty difficult to explain, but this is basically how you do it when you want to see how many combinations of something there are for multiple different things. Basically, for each of the 5 shirts, there are 3 different pants, and for each of the pants there are 4 shoes. So each pant has 4 shoes, then multiply that by 3 for the 3 pants for each shirt. After that, multiply by 5 for each shirt in the outfits.

A toy cannon ball is launched from a cannon on top of a platform. the equation h(t)=-5t^2+15t+10 gives the height h, in meters, of the ball t seconds after it is launched.

B)Explain your answer

Hello,
This is a parabola.
The vertex is for x= 15/2*5=3/2, and then the maximum is reached for
[tex]h(3/2)=-5(9/4)+15(3/2)+10=\dfrac{-45+90+40}{4}=\dfrac{85}{4}[/tex]
As 85/4 < 24 the ball does not reach a height of 24 m
thanks
The ball does not reach a height of 24 m.
What is Parabola?Any point on a parabola is at an equal distance from both the focus, a fixed point, and the directrix, a fixed straight line. A parabola is a U-shaped plane curve. The topic of conic sections includes parabola, and all of its principles are discussed here.
Given:
The height of the toy cannon all launched is expressed as
h(t)=-5t²+15t+10
a) As, the given equation forms a parabola, the vertex is
t = 15/2 x 5
t = 3/2
So, it reached the maximum height at 3/2
h(3/2) = -5(9/4)+ 15 (3/2) + 10
h(3/2) = 85/4
So, 85/4 < 24 the ball does not reach a height of 24 m.

Answer:
17
Step-by-step explanation:
The answer is 17 because the operation PEMDAS
Answer:
17
Step-by-step explanation:
20/ 4+6x2 can be simplified. First, you can divide 20 by 4 because of the order PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction) 20 divided by 4 is 5. You can then multiply 6 and 2 which gives you 12. Therefore, your equation is down to 5+12. You can add those two and you get 17 :) Hope this helps!! :D ~Happy Halloween~

A coin is tossed and a six​-sided die numbered 1 through 6 is rolled. Find the probability of tossing a head and then rolling a number greater than 5.
Answer:
1/12Step-by-step explanation:
This type of probability is independent i.e the occurrence of one does not affect the other.
Probability = expected outcome/total outcome
For a coin:
The total sample space = {H, T} i.e 2
The probability of tossing a head will be:
P(a head) = 1/2
For a die:
Sample space S = {1, 2, 3, 4, 5, 6}
Total number of sample space n(S) = 6
If a number greater than 5 is rolled, the event outcome will be E = {6}
Pr(S>5) = n(E)/n(S)
Pr(S>5) = 1/6
The probability of tossing a head and then rolling a number greater than 5 is expressed as:
Pr(H and S>5) = Pr(H) * Pr(S>5)
Pr(H and S>5) = 1/2* 1/6
Pr(H and S>5) = 1/12
Hence the probability of tossing a head and then rolling a number greater than 5 is 1/12

1.4.AP-6 3 Question Help The calorie count of a serving of food can be computed based on its composition of carbohydrate, fat, and protein. The calorie count C for a serving of food can be computed using the formula C = 3h + 13f + 7p, where h is the number of grams of carbohydrate contained in the serving, f is the number of grams of fat contained in the serving, and p is the number of grams of protein contained in the serving. Solve this formula for f, the number of grams of fat contained in a serving of food.
Answer:
f = (C-3h-7p)/13Step-by-step explanation:
Given the equation of calorie count of food computed by:
C = 3h + 13f + 7p
h is the number of grams of carbohydrate contained in the serving,
f is the number of grams of fat contained in the serving, and;
p is the number of grams of protein contained in the serving
We are to make f the subject of the formula as shown:
C = 3h + 13f + 7p
13f = C-3h-7p
Divide through by 13
13f/13 = (C-3h-7p)/13
f = (C-3h-7p)/13
Hence the formula for f, the number of grams of fat contained in a serving of food is f = (C-3h-7p)/13

People in a public library were polled on how many books they read in the last five years. Preliminary survey results indicate the sample standard deviation is 18.61 books. How many subjects are needed to estimate the mean number of books read by library users in the last five years within four books with 99% confidence
Answer:
144
Step-by-step explanation:
From information available
Margin of error = 4
S = 18.61
ME = Z-alpha/2 x s/√n
Alpha = 1-0.99
= 0.01
Alpha/2 = 0.01/2
= 0.005
Z-alpha/2 =2.576
Putting into the formula we have
4/1 = 2.576 x 18.61/√n
When we cross multiply
We have
√n = (2.576 x 18.61)/4
√n = 11.98484
n = 11.98484²
n = 143.63
n = 144
144 subjects are needed to do this estimation

Suppose the average wait time for a sandwich at a local deli is 55 min with a standard deviation of 33 min. Is it unusual to wait over 1212 minutes to get a sandwich?
Answer:
The wait time is unusual because the probability value obtained is less than 2 standard deviation above the mean
Step-by-step explanation:
From the question we are told that
The average wait time is [tex]\mu = 55 \ min[/tex]
The standard deviation is [tex]\sigma = 33 \ min[/tex]
Generally the probability of waiting over 1212 minutes is
[tex]P(X > 1212) = P(\frac{X - \mu}{ \sigma } > \frac{ 1212 - 55}{ 33} )[/tex]
[tex]P(X > 1212) = P(\frac{X - \mu}{ \sigma } > \frac{ 1212 - 55}{ 33} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
So
[tex]P(X > 1212) = P(Z > 35 )[/tex]
From z table the probability of (Z > 35 ) is
[tex]P(Z > 35 ) = 0[/tex]
Hence
[tex]P(X > 1212) = 0[/tex]
The time is unusual because the probability value obtained is less than 2 standard deviation above the mean
