Please give me an explanation.

Using a t-distribution calculator, it is found that the critical value of t* for a 98% confidence interval with 25 observations is given by:

B. t* = 2.492

It is found using a calculator, with two inputs, which are given by:

In this problem, we have a confidence level of 98% and 25 - 1 = 24 df, hence the critical value is of t* = 2.492, which means that option B is correct.

Answer:

[tex]y=11x-3[/tex]

Step-by-step explanation:

Given ordered pairs:

(1, 8)  (2, 19)  (3, 30)  (4, 41)

As the y is directly proportional to x (y values increase +11 for every +1 increase for the x-values) then the equation will be linear.

Point-slope form of a linear equation:  [tex]y-y_1=m(x-x_1)[/tex]

(where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex] is a point on the line)

[tex]\textsf{slope }m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Let:

[tex]\implies \textsf{slope }m=\dfrac{19-8}{2-1}=11[/tex]

Using point-slope equation with m = 11 and point (1, 8):

      [tex]y-y_1=m(x-x_1)[/tex]

[tex]\implies y-8=11(x-1)[/tex]

[tex]\implies y=11x-3[/tex]

Answer:

you will multiply the new price plus the original price

Answer:

12 edges, 6 faces, and 7 vertices.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

I say 12 edges because there are 12 meeting points, and an open shape.

6 faces because there are 6 highlighted points on what looks like an unfolded shape.

8 vertices because you add 2 to the number of edges and subtract by the number of faces, 6.

Step-by-step explanation:

= (7+20+9+35+12+15+7+10+20+25) : 10

with 10 = number of values

average distance = 160 : 10 = 16

Answer:

35°

Step-by-step explanation:

There are 4 angles in quadrilateral which is equal to 360°. So...Add 100°, 110° and 80° and you will get 290°. Then, substract 290° from 360°. So you will get 70° which is Angle B. and then there's a straight line crossing the angle B. So divide with 2. You will get 35° which is equal to angle x because of the straight line.

Step-by-step explanation:

The 53rd ball will be blue. I don't really know how to explain but I'll try.

So there are black, white and blue balls. If you look closer you'll see that the words 'black,white,blue,black, blue were repeated twice. So let's say that the first 5 letters are a set. To get the 50th color, all you have to do is 5 × 10 which is 50 and the 50th term is blue. Just add black(51st), white(52nd) and you'll get the 53rd color to be Blue.

Answer:

Colombian coffee bought = 0.5 lbs

French roast coffee beans bought = 0.5 lbs

Step-by-step explanation:

Let Colombian coffee bought = [tex]x[/tex] lbs

Total weight of mixture bought = 1 lbs

Therefore, French roast coffee beans bought = (1 - [tex]x[/tex]) lbs

Price of 1 lb Colombian coffee = $4.25

Price of [tex]x[/tex] lbs of Colombian coffee = $[tex]4.25x[/tex]

Price of 1 lb French roast coffee beans = $3.75

Price of (1 - [tex]x[/tex]) lbs French roast coffee beans = $3.75(1 - [tex]x[/tex])

It is given that total money spent is $4.

As per given statement:

[tex]4.25x+3.75(1-x)=4\\\Rightarrow 0.50x=0.25\\\Rightarrow x=\bold{0.5\ lbs}[/tex]

Colombian coffee bought = 0.5 lbs

French roast coffee beans bought = 0.5 lbs

Use the slope formula to find the slope  m .

Step-by-step explanation:

Hope this helped : )

The slope of the line that passes through the points (-4, -2) and (-4, -22) is an infinite slope.

The slope of a line can be found using the formula below.

Therefore,

x₁  = -4

x₂ =  - 4

y₁ = -2

y₂ = -22

Therefore,

m = -22 - (-2) / - 4 - (-4)

m = -22 + 2 / - 4 + 4

m = 20 / 0

m = infinity

The slope is an infinite slope.

Answer: 4.00, 9.00, 11.00, 4.00

Step-by-step explanation:

When we round, we round from the digit one smaller than the one we're rounding to. In this case, since we're rounding to the dollar, we round from the 10th place. To round, we need to know whether the number we're rounding from is smaller than, equal to, or larger than 5. If the number is smaller than 5, we round down. Larger, and we round up. If the number is equal to 5, we also round up.

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

Make 5 a fraction which would be 5/1

Then make an expression, "5/1 /  1/4"

Then switch and flip meaning make the division sign a multiplication sign and make 1/4 into 4/1.

Your expression should look like 5/1 x 4/1

Then multiply 5 and 4 and you get 20. You do not need to write it as a fraction.

Answer:

His March Earnings is $20000

Step-by-step explanation:

Given

[tex]Salary = \$1500[/tex]

[tex]Commission = 5\%\ of\ sales[/tex]

[tex]March\ Earnings = \$2500[/tex]

Required

Determine the monthly sales

Represent the monthly sales with x

The march earnings can be determined using:

[tex]March\ Earnings = Salary + Commission[/tex]

[tex]March\ Earnings = Salary + 5\%\ of\ x[/tex]

Substitute values of March Earnings and Salary

[tex]2500 = 1500 + 5\% * x[/tex]

[tex]2500 = 1500 + 0.05 * x[/tex]

[tex]2500 = 1500 + 0.05x[/tex]

Solve for 0.05x

[tex]0.05x = 2500 - 1500[/tex]

[tex]0.05x = 1000[/tex]

Solve for x

[tex]x = 1000/0.05[/tex]

[tex]x = 20000[/tex]

Hence:

His March Earnings is $20000
