1. [tex]\frac{3}{8}[/tex]
2. [tex]\frac{1}{4}[/tex]
3a. [tex]-\frac{1}{4}[/tex]
3b. 3
3c. [tex]-\frac{4}{5}[/tex]
4. [tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]
Step-by-step explanation:
1.
Rises 6 inches for every horizontal change of 16 inches
Slope = rise/run
Slope = 6/16
Slope = 3/8
2.
Rises 3 feet for every horizontal change of 12 feet
Slope = rise/run
Slope = 3/12
Slope = 1/4
3a.
[tex]m = \frac{y_1 - y_2}{x_1-x_2}[/tex]
[tex]m = \frac{3-2}{-2-2}[/tex]
[tex]m = \frac{1}{-4}[/tex]
[tex]m = -\frac{1}{4}[/tex]
3b.
[tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]
[tex]m = \frac{-1 - 2}{-1-0}[/tex]
[tex]m = \frac{-3}{-1}[/tex]
[tex]m = 3[/tex]
3c.
[tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]
[tex]m = \frac{1 - (-3)}{-1-4}\\[/tex]
[tex]m = \frac{4}{-5}\\[/tex]
[tex]m = -\frac{4}{5}[/tex]
4.
[tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]

here are the prices of 5 new bicycles in dollars 25,30,50,77,80. The standard deviation is about $26.If a 6th bike is added to the sample that has a price of $400 what happens to the standard deviation?
Answer:
The new standard deviation will be greater than $26
Step-by-step explanation:
The new bicycle has a price much larger than the price of the others. In fact it is almost double the price of the other bicycles. It causes a large increase as a result. Also, I took the quiz.

Jazzmine took out a loan of $17,500 to buy a new car. She received a 3.5% interest rate compounded annually and paid $3,274.50 in interest. How long did it take Jazzmine to pay off the loan?
Answer:
Time period = 5 year (Approx.)
Step-by-step explanation:
Given:
Amount of loan = $17,500
Rate of interest = 3.5% compounded annually
Amount paid as interest = $3,247.5
Find:
Time period
Computation:
Using compounded interest formula
I = P[(1+r)ⁿ - 1]
3,247.50 = 17,500[(1+3.5%)ⁿ - 1]
3,247.50 = 17,500[(1+0.035)ⁿ - 1]
3,247.50 = 17,500[(1.035)ⁿ - 1]
Time period = 4.948
Time period = 5 year (Approx.)

Answer:
[tex]r=\dfrac{PV}{nT}[/tex]
Step-by-step explanation:
The given equation is :
[tex]PV=nrT[/tex]
Where
P is pressure
V is volume
n is no of moles
r is Gas constant
T is temperature
We need to solve the above equation for r.
Dividing both sides of the above equation by (nT). So,
[tex]\dfrac{PV}{nT}=\dfrac{nrT}{nT}\\\\r=\dfrac{PV}{nT}[/tex]
So, the value of r is equal to [tex]\dfrac{PV}{nT}[/tex].

Answer:
Step-by-step explanation:
25 - (9 - y) = 20.7
Putting value of y = 4.3 in equation
25 - (9 - 4.3) = 20.7
25 - 4.7 = 20.7
20.3 = 20.7
Bringing like terms on one side
20.7 - 20.3 = 0.4
Answer; in this question we should have to put the value of y=4.3 and then we will get the answer.
Step-by-step explanation:
25-(9-y)=20.7
25-(9-4.3)=20.7
25-(4.7)=20.7
20.3=20.7
Bring the term on one side
20.7-20.3=0.4 Answer
We are told that the data is representative of the two populations (U.S. males aged 20-29 years and U.S. males aged 75+ years), and we will assume that researchers collected random samples. The samples are very large; therefore, the conditions are met for use of the T-test. Using StatCrunch, we find a T-score of 5.3 and a P-value of "< 0.0001." What can we conclude? Group of answer choices The data prove that, in the U.S., young men weigh about 4.9 kgs more on average than old men. The data suggest that young men weigh more on average than old men in the U.S., but that the difference in mean weights for the two groups is not statistically significant. The data provide strong evidence that young men weigh more on average than old men in the U.S. no conclusion is possible because we did not specify a significance level
Answer:
The data provide strong evidence that young men weigh more on average than old men in the U.S
Step-by-step explanation:
Given :
The null hypothesis ; H0 : μ1 = μ2
The alternative hypothesis ; H1 : μ1 > μ2
T score = 5.3 ; Pvalue = < 0.0001
The decision region :
If Pvalue < α ; We reject the Null
If Pvalue > α ; We fail to reject the Null
When the α - level isn't stated, we usually assume a α - level of 5%
However, even at lower alpha level of 1% = 0.01 ;
The Pvalue < α
Hence, we can conclude that there is significant evidence that there is difference in the mean weight of young men and old men in the U.S

Determine the missing length in each right triangle using the Pythagorean theorem. Round the answer to the nearest tenth, if necessary.
Answer:
answer is 9 yd
Step-by-step explanation:
The missing length in right triangle by using the Pythagorean theorem is,
⇒ 9 yards
What is Pythagoras theorem?
The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
We have to given that;
In a right triangle,
Hypotenuse = 15 yd
Perpendicular = 12 yd
Hence, By Pythagoras theorem;
Base² = 15² - 12²
Base² = 225 - 144
Base² = 81
Base = √81
Base = 9 yards
Thus, The missing length in right triangle by using the Pythagorean theorem is,
⇒ 9 yards
