Answer:
-6/6 or -1
Step-by-step explanation:
To find the equation of the line (or the slope, assuming that's what equation means, ) we need to write the formula Y1-Y2/X1-X2
So, we need to fill in the numbers, which gives us the fraction -6-0/-2-(-8)
When we solve for the numerator (-6-0), we get -6.
When we solve for the denominator (-2 - {-8}), we get 6.
So, we have -6/6, which, when simplified, is -1.
(If the problem is not asking for slope when it says equation, then sorry!)

Step-by-step explanation:
Using the same scenario as above, but now you do not know the population variance. You collect a random sample of n = 21 cereal boxes and find the sample mean is 12.8 and the sample standard deviation to be 0.5. Test the null hypothesis H0: µ = 13 against the alternative hypothesis HA: µ < 13 at level of significance α = 0.01.
Required:
a. Find the test statistic.
b. Using the rejection region, do you reject or not reject the null hypothesis?
c. Find the p-value.
d. Using the p-value, do you reject or not reject the null hypothesis?
e. In context of your problem, what is your conclusion about the ounces contained in cereal boxes?
Answers
Answer:
-1.833 ; we do not reject the Null.
Pvalue = 0.0409 ; We do not reject the Null
There is no significant evidence to conclude that the number of ounces contained in the cereal boxes is less than 13
Step-by-step explanation:
H0 : μ = 13
HA : μ < 13
Test statistic :
(xbar - μ) ÷ s/sqrt(n)
(12.8 - 13) ÷ 0.5/sqrt(21)
-0.2 / 0.1091089
= - 1.833
The critical value at α = 0.01 ; df = 21 - 1 = 20 = 2.528
-1.833 > - 2. 528 (left tailed test) ; Hence we do not reject the Null.
Test statistic :
Pvalue from Test statistic at DF = 20 ; α = 0.01
Pvalue = 0.0409
Pvalue > α
0.0409 > 0.01 ; Hence, we do not reject H0.
There is no significant evidence to conclude that the number of ounces contained in the cereal boxes is less than 13
Suppose 10 tosses of a coin were all heads, and you switch to a new coin. What is the probability of tossing this new coin and getting another head?
Answers
Answer:
50% or 1/2 Could be 100% but i think it is 50%
Step-by-step explanation:
Because Changing the coin will make no difference.
The probability of getting heads is same as the probability of tails which is [tex]\frac{1}{2}[/tex].
What is the probability?
The concept of probability is used to assign a numerical description to the likelihood of occurrence of an event.
Probability can be defined as the number of favorable outcomes divided by the total number of possible outcomes of an event.
Here given that,
The [tex]10[/tex] tosses of a coin were all heads, and you switch to a new coin.
So, the probability of getting all heads is [tex]2^{-n}[/tex]
And we have [tex]n=10[/tex],
Then, the probability of getting the heads is
[tex](^{n}C_k)(\frac{1}{2})^k(\frac{1}{2})^{n-k}=2^{-n}(^nC_k)[/tex]
Hence, the probability of getting heads is same as the probability of tails which is [tex]\frac{1}{2}[/tex].

Riley's grandparents drive from city A to city B every spring. It takes them several days. Each day they use the expression 2+ distance over 54 to figure out how many hours they will be on the road. The first day they were on the road for 7 hours. How far did they travel on the first day?
Answers
9514 1404 393
Answer:
270 miles
Step-by-step explanation:
For h hours of driving the distance d is covered:
h = 2 +d/54
Solving for d, we find the distance covered in h hours is ...
d = 54(h -2)
In 7 hours, the distance they traveled is ...
d = 54(7 -2) = 270 . . . miles
They traveled 270 miles on the first day.

Step-by-step explanation:
Shanna is planning a trip from Dallas, Texas, to San Diego, California.
She will travel about = 1,400 miles
The scale of a map is 300 miles = 1 inches
The trip of 1,400 miles = [tex]\frac{1400}{300}[/tex]
= 4.66666 inches ≈ 4.67 inches
Her trip is 4.67 inches far on the map.
g(x) = 2x – 4
h(x)=x²-3
Find (g.h)(5)
Answers
Answer:
40
Step-by-step explanation:
This is asking you to plug in the value of h(5) into g(x). First solve for h(5)
x^2-3 = h(x)
5^2-3= 22
h(5) = 22
h(5) is 22. So now, plug that into g(x).
g(h(5)) = 2(22)-4
44-4=40
(g.h)(5) is 40.

Let x denote the length of the side of each cut-out square. Assume negligible thickness. (a) Find a formula for the volume, V, of the box as a function of x. \ \ V(x)
Answers
Answer:
Volume=[tex]4x^3-44x^2+112x[/tex]
Step-by-step explanation:
Let x denotes the length of the side of each cut
After Cutting square length will be=8-2x (where 2x for 2 squares as on each side two corners are there thus 2 squares will be cut down)
After cutting square width will be=14-2x (where 2x for 2 squares as on each side two corners are there thus 2 squares will be cut down)
Height = x
Volume=Length*width*Height
Volume=(8-2x)*(14-2x)*x
On solving we will get:
Volume=[tex]4x^3-44x^2+112x[/tex]
Mountain officials want to build a new ski lift from B to C, as shown in the figure below. The distance from A to C is 1540 feet. They measure angle DAC to be 38º and angle DBC to be 25º. What is the distance from A to B ? Round your answer to the nearest tenth of a foot.
Answers
Answer:
there is a 13 degree difference from DBC and DAC
with that you divide 1540 by 13 as you get that 118.461 feet
that means that there is a 118.461 difference from B to C and A to B
so the answer is either 1658.461ft or 1421.539ft I am not sure if that is correct or not but best of luck mate

1. attendance (y), time (x)
2. 1,2: increasing; 3: constant; 4: decreasing
3. attendance increases, remains constant, then decreases
4. increasing; pre-heating the oven
Step-by-step explanation:
It is always difficult to read the mind of the author of questions like these. Usually, specific wording is expected. If your curriculum material has examples you can copy from, you should do that.
__
1. The variables and what they stand for are listed on the axes of the graph. The y-variable stands for attendance. The x-variable stands for time. It isn't clear whether the desired answer is "y and x" or "attendance and time".
__
2. The graph slopes upward in intervals 1 and 2. It can be described as "increasing."
The graph remains level in interval 3. It can be described as "constant."
The graph slopes downward in interval 4. It can be described as "decreasing."
__
3. The attendance is adequately described in question 2. Attendance increases, remains constant, then decreases. It isn't clear how general or specific the answer is supposed to be.
__
4. The graph of the function is "increasing." We don't know if the indicated temperature is the temperature of the bread, the oven, or the room containing the oven. If we assume the indicated temperature is that of the oven, we expect an increase during the oven pre-heat interval.
If the indicated temperature is that of the bread, then the increase would be following insertion of the bread into the oven.
