What is the slope of the ling in the graph?
Answer:
1
Step-by-step explanation:
Start at any point on the line. Go up 1 and right 1. Now you are on another point on the graph. That is rise = 1 and run = 1.
Slope = rise/run = 1/1 = 1
Answer: 1

Assume that you have a sample of n1=9, with the sample mean X1=46, and a sample standard deviation of S1=4, and you have an independent sample of n2=12 from another population with a sample mean of X2=31 and the sample standard deviation S2=5. Complete parts (a) through (d) below. a. What is the value of the pooled-variance tSTAT test statistic for testing H0: μ1=μ2? tSTAT=nothing (Round to two decimal places as needed.) b. In finding the critical value, how many degrees of freedom are there? nothing degrees of freedom (Simplify your answer.) c. Using a significance level of α=0.1, what is the critical value for a one-tail test of the hypothesis H0: μ1≤ μ2 against the alternative H1: μ1>μ2? The critical value is nothing. (Round to two decimal places as needed.) d. What is your statistical decision? A. Reject H0 because the computed tSTAT test statistic is greater than the upper-tail critical value. B. Reject H0 because the computed tSTAT test statistic is less than the upper-tail critical value. C. Do not reject H0 because the computed tSTAT test statistic is less than the upper-tail critical value. D. Do not reject H0 because the computed tSTAT test statistic is greater than the upper-tail critical value.
Answer:
a. t`= 7.63
b.υ = [s₁²/n1 + s₂²/n2]²/ (s₁²/n1 )²/ n1-1 + (s₂²/n2)²/n2-1
= 18.885 ≈19 The degrees of freedom is always rounded in this calculation.
c. The critical region for one tailed test for alpha= 0.1 and 19 degrees of freedom is 1.328= 1.33
The critical region is ║t║` ≥ t 0.05,19 = 1.729= 1.73
A. Reject H0 because the computed tSTAT test statistic is greater than the upper-tail critical value
Step-by-step explanation:
Answer:
Step-by-step explanation:
We state our null and alternative hypothesis as
H0: μ1=μ2 against Ha: μ1 ≠ μ2
The level of significance is α=0.1
Since the population have unequal variances , the test statistic if H0 is true ,is
t`= x1`- x2`/ √s₁²/n1 + s₂²/n2
which has approximately a t- distribution with υ degrees of freedom where
υ = [s₁²/n1 + s₂²/n2]²/ (s₁²/n1 )²/ n1-1 + (s₂²/n2)²/n2-1
Computations:
t`= x1`- x2`/ √s₁²/n1 + s₂²/n2
t`= 46-31/ √4²/9 + 5²/12
t`= 15/√16/9 +25/12
t`= 15/ √64+75/36
t`=15/1.9649
t`=7.6339
t`= 7.63
υ = [s₁²/n1 + s₂²/n2]²/ (s₁²/n1 )²/ n1-1 + (s₂²/n2)²/n2-1
= [139/36]²/ (16/9)²/8 +(25/12)²/11
= 14.91/ 0.395 + 0.395
= 18.885
≈19 The degrees of freedom is always rounded in this calculation.
The critical region is ║t`║≥ t 0.05,19 = 1.729
Since the calculated value of t` falls in the critical region we reject our null hypothesis of equal means.

Answer:
Drink A
Step-by-step explanation:
Let's find the amount of sugar in each drink in every 35 ounces. (since 35 is the lowest common multiple of 5 and 7)
Drink A
5 fluid ounces --- 11g of sugar
35 fluid ounces --- 11 ×7= 77g of sugar
Drink B
7 fluid ounces --- 10g of sugar
35 fluid ounces --- 10 ×5= 50g of sugar
Since drink A has more sugar in every 35 ounces than drink B, drink A is sweeter.

t, for which Company A is cheaper than Company B.
Answer
10 hours
Explanation
Step one:
given information
Company A
charges $45 per hour and a $150 equipment fee.
Let A represent the amount Company A would charge for t hours
So, the expression for the total is
A= 45t+150--------------------1
Company B
charges $35 per hour and a $200 equipment fee.
Let B represent the amount Company B would charge for t hours
So, the expression for the total is
B= 35t+200--------------------2
Step two:
equating the two equations above
A=B
45t+150=35t+200
collect like terms
45t-35t= 200-150
5t=50
divide both sides by 5
t=50/5
t=10

At ShopRite, chicken sells for $3.75 per pound. How much would it cost to buy 2.25 pounds of chicken?
Answer: 8.4375 U.S. dollars2
Step-by-step explanation:
Answer:
$8.44
Step-by-step explanation:
From the question it self we know that 1 pound of chicken costs $3.75. In order to solve this question we just need to find out how much 1 pound does fit into 2.25 pounds and then multiple the result by $3.75. We can find that out by dividing 2.25 by 1, and we get 2.25. Then we do the following....
2.25 x $3.75 = $8.4375
We got $8.4375 as an answer but we have to remember that when we are talking about money and we have to round to the nearest cent (which is equal to 1 hundredth of a dollar). So now we just have to round to the nearest hundredth, and we get $8.44 as our answer.

Your value to live in a quiet apartment is $400. The neighbor living above your apartment makes noise using her treadmill every day. She values running at $500. Your neighbor has the right to run in her apartment. If the proper conditions are met, what does the Coase Theorem suggest is the likely outcome in this case
Answer:
continuation
Step-by-step explanation:
Since you value a quiet apartment at $400, which is less than $500, you might offer $400 for your neighbor to stop, but she values running higher, so she would likely refuse, resulting in the continuation of what's happening.
The correct statement to the given query is "The neighbor pays you $401 to continue running".
Coase's theorem predicts that throughout the face of such an external cost, contracting groups or two entities would be prepared to arrange as well as achieve a satisfactory solution.Because of this, one's neighbor would then compensate them at minimum the worth of their condominium so that he would rather start operating upon the treadmills.Learn more about Coase theorem here:

(2,-3), slope = 4
What is the answer
We are given:
The line passes through (2,-3)
Slope of the line = 4
Finding the equation of the line:
We know that the general form of the slope-intercept form is:
y = mx + b [where m is the slope and b is the y-intercept]
y = 4x + b [since slope = 4]
Finding the y-intercept:
Now, we are given that the line passes through the points: (2,-3)
which can be written as: x = 2 and y = -3
Since the line passes through these points, these values must satisfy the equation
So,
y = 4x + b
-3 = 2(4) + b
-3 = 8 + b
b = -11 [subtracting 8 from both sides]
Hence, the y-intercept is -11
Equation of the line:
We wrote the equation of the line as:
y = 4x + b (where b is the y-intercept)
now that we know the value of b,
y = 4x - 11
Therefore, the equation of the line is: y = 4x - 11
4x + 6y = 16
x = –8
Solve for x, y
I think the answer is yes=8

Answer:
1. m<UTV=m<STR Vertical angles
2. m<R+ m<S+m<T. Triangles must add up to 180°
3. 3x+2x+85°=180°. Substitution
4. X=19. Algebra
Step-by-step explanation:
So basically we look at angle UTV and it equals to 85 degrees. We have to find another angle that equals 85 degrees and to do this we have to find a vertical angle congruent angle which here is angle RTS and this equals 85 degrees.
Next just use sum of angles in triangle from RTS.
Then substitute the values from angle RTS.
3x + 2x + 85 = 180
Solve for x.

The product of three positive integers is 300. If one of them is 5, what is the
least possible value of the sum of the other two?
Answer and Step-by-step explanation:
So, we are told that 3 positive integers multiply to be 300, and that one of the integers is 5.
First, we divide 300 by 5.
The result is 60.
Now, we take different (reasonable) numbers that add to 16:
10 and 6
12 and 4
We can see here that 10 and 6 are the integers because they add up to 16 and multiplies to 60.
