Consider a right-tailed test (upper tail) and a sample size of 40 at the 95% confidence level. The value of t is ________.
a. +2.023
b. -2.023
c. -1.685
d. +1.685
Answers
Answer:
The correct option is d.
Step-by-step explanation:
The directional hypothesis is:
[tex]H_{a}:\mu>\mu_{0}[/tex]
The sample size is, n = 40.
The significance level is:
[tex]\alpha =1-0.95=0.05[/tex]
Use the t-table to compute the right-tailed t-critical value as follows:
[tex]t_{\alpha,\ (n-1)}=t_{0.05, (40-1)}[/tex]
[tex]=t_{0.05, 39}\\\\\approx t_{0.05, 40}\\\\=1.684\\\\\approx 1.685[/tex]
The value is positive since the directional hypothesis suggests that the test is right tailed.
The correct option is d.

If the value of "y" varies directly with "x"
and y = -8 when x = 4.
Find "y" when x = -4.
Answers
Answer:
-16
Step-by-step explanation:
because y varies directly with 4 when you remove 8 from 4 you get -4 and when you remove it from -8 you get -16
The value of y is 8 for the given condition.
What is linear equation?Linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. Generally, the equation is of the form Ax+B=0.
For the given situation,
The value of "y" varies directly with "x" and y = -8 when x = 4.
First we need to form the equation for this condition as [tex]y=kx[/tex].
Here, x=4 and y=-8
⇒ [tex]-8=k(4)[/tex]
⇒ [tex]k=-2[/tex]
Now substitute the value of k and x=-4 in the above equation to get the value of y,
⇒ [tex]y=kx[/tex]
⇒ [tex]y=(-2)(-4)[/tex]
⇒ [tex]y=8[/tex]
Hence we can conclude that the value of y is 8 for the given condition.

A bookshelf sits on top of a large desk. Together, their height is 6.75 feet. The difference between their heights is 1.85 feet. How tall is the bookshelf?? Let the height of the bookshelf = x and the height of the desk = y.
Answers
Answer: 4.9
Step-by-step explanation:
The height of the bookshelf is 4.3 feet and the height of the desk is 2.45 feet.
What is the system of equations?Simultaneous equations are any one or more equations that can have the same number of unknowns and be solved concurrently. The system of equations is a simultaneous equation.
Given:
A bookshelf sits on top of a large desk.
Together, their height is 6.75 feet.
The difference between their heights is 1.85 feet.
Let the height of the bookshelf = x and the height of the desk = y.
x + y = 6.75 {equation 1}
x - y = 1.85 {equation 2}
Add both equations,
we get,
2x = 6.75 + 1.85
2x = 8.6
x = 4.3
And from equation 2,
y = 2.45
Therefore, the solution is x =4.3 and y = 2.45.

i need help with these 9 questions they’re pretty simple
Answers
Answer:
1. n = 4
2. n = -29
3. n = -28
4. n = -48
5. n = -22
6. n = 97
7. n = 220
8. n = -18
9. n = 36
Step-by-step explanation:
1. -n = -4
Multiply both by -1 to get n = 4
2. 12 + n = -17
Subtract 12 from both sides of the equation to get n = -29
3. -n/14 = 2
Multiply by 14 on both sides of the equation to get -n = 28
Multiply -1 on both sides of the equation to get n = -28
4. -42 = n + 6
Subtract 6 from both sides of the equation to get -48 = n or n = -48
5. -4n = 88
Divide -4 on both sides of the equation to get n = -22
6. n + -3 = 94
Add 3 to both sides of the equation to get n = 97
7. 11 = -n/-20
Multiply by -20 on both sides of the equation to get -220 = -n or -n = -220
Multiply -1 on both sides of the equation to get n = 220
8. -108 = 6n
Divide by 6 on both sides of the equation to get -18 = n or n = -28
9. 67 = 31 + n
Subtract 31 from both sides of the equation to get 36 = n or n = 36

What is the slope of the line that passes through the points (8, 7)(8,7) and (4, 5) ?(4,5)? Write your answer in simplest form.
Answers
Work shown in attached image:
The slope of the line is 1 / 2. The equation of the line is y = 1/ 2 x + 3.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the line passes through points (8, 7) and (4, 5). The slope of the line will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 5 - 7 ) / ( 4 - 8 )
Slope = -2 / -4
Slope = 1 / 2
Calculate the y-intercept,
y = mx + c
5 = 1 / 2 x 4 + c
c = 5 - 2 = 3
The equation is written as,
y = mx + c
y = 1/2x + 3
Therefore, the slope of the line is 1 / 2. The equation of the line is y = 1/ 2 x + 3.

Answers
Answer:
28.45%
Step-by-step explanation:
The price of a new cell phone = $225
With the extended warranty, the total cost comes to $289.
We need to find the percent of the purchase price is the price of the warranty. It can be calculated as follows :
[tex]\%=\dfrac{|\text{purchase price-extended warrenty price}|}{\text{purchase price}}\times 100\\\\=\dfrac{|225-289|}{225}\times 100\\\\=28.45\%[/tex]
