a) find t0.005 when v=6. (b) find t0.025 when v=11. (c) find t0.99 when v=18.

Answers

Answer 1

a) To find t0.005 when v = 6, we need to look up the value in a t-distribution table with a two-tailed area of 0.005 and 6 degrees of freedom. From the table, we find that t0.005 = -3.707.

b) To find t0.025 when v = 11, we need to look up the value in a t-distribution table with a two-tailed area of 0.025 and 11 degrees of freedom. From the table, we find that t0.025 = -2.201.

c) To find t0.99 when v = 18, we need to look up the value with a one-tailed area of 0.99 and 18 degrees of freedom. From the table, we find that t0.99 = 2.878. Note that we only look up one-tailed area since we are interested in the value in the upper tail of the distribution.

Are the ratios 18:9 and 4:3 equivalent?

Answers

No
18/4 is 4.5
9/3 is 3
So ur answer is no

Answer:

No. (see below)

Step-by-step explanation:

If you match up the ratios like this:

18 : 9

4 : 3

Matching the two numbers (one on top of another, since they correspond to each other), you can see that these are not equivalent.

Here's why:

The top ratio is 18 to 9, which can be represented by 18 total people to 9 girls in the amount of total people.

We know that the number of boys will also be 9 because 9 is half of 18.

Let's look at the second ratio:

This can be represented by 4 total people to 3 girls in the amount of total people.

4 - 3 = 1

So there would be only 1 boy. Meaning that they're not equal because 1 is not half of 4. It would only be 1/4.

1/4 ≠ 1/2

If we make them similar denominators, you can really see it:

1/4 ≠ 2/4

Which equation represents the total cost of a repair by an electrician after x hours?
An electrician charges $90 per hour plus a $50 travelling fee.

Answers

Answer:

y = 90x + 50

Step-by-step explanation:

In this situation, let's define the variable and the constant.

The variable is what changes, so in this case the wage ($90) changes with how many hours the electrician is hired for.

The constant is the number that stays the same, in this case it would be the $50 traveling fee because it remains the same every time.

The equation should be written in this form:

y = mx + b

m = slope (variable)

b = y-intercept (constant)

Therefore, you can write the equation like this:

y = 90x + 50

1. Dolores is on a bridge that is 42 feet above a lake. What is the distance from Dolores to the boat? G​

Answers

Answer:

See answer below

Step-by-step explanation:

You are missing data such as the angle of the boat next to Dolores. I found an exercise similar to this, and I'm going to show it here and use the missing data to show you how to do it:

Dolores is on a bridge that is 45 feet above a lake. She sees a boat at a 30 degree angle of depression. What is Dolores' approximate horizontal distance from the boat?

According to that, I will use the angle of 30° to do this, but the distance of 42 feet.

Now, we can see this as a triangle. Dolores is on a bridge 42 feet above a lake, this 42 feet distance should be one side of the triangle (The vertical forming the 90° angle), and the boat that is on the lake, is seen with an angle of 30°. So the distance of the boat, to the spot where dolores is, under the bridge would be the horizontal side.

With this, we have the opposite side (a) and the adyacent side (b) of the triangle, and we have the angle, therefore:

tanα = a/b

Replacing we have:

tan30° = 42/b

b = 42 / tan30°

b = 72.75 feet

Hope this helps

A.

B.

C.
x > 5
D.
x > 7

Answers

Answer:

D. x > 7

Step-by-step explanation:

The mine operates x hours per day and extracts 2 tons of ore per hour.

The amount of ore extracted as a function of hours of operation is

2x

The mine must produce 4 tons plus more than 10 tons each day. The mine must produce more than 14 tons in one day. That means that 2x must be greater than 14.

2x > 14

Divide both sides by 2.

x > 7

Answer: D. x > 7

The area of a rectangle is 735 in squared. The ratio of the length to the width is 5 : 3. Find the length and the width.

Answers

Answer: Length = 35

Width = 21

Step-by-step explanation:

From the question, we are informed that the area of a rectangle is 735 in squared and that the ratio of the length to the width is 5 : 3.

To find the length and the width of the rectangle goes thus. We should note that the area of a rectangle is the length multiplied by the width.

Therefore, 5x × 3x = 735

15x² = 735

x² = 735/15

x² = 49

x = ✓49

x = 7

Recall that length = 5x = 5 × 7 = 35

Width = 3x = 3 × 7 = 21

Answers

Answer:

m= 7.50

Step-by-step explanation:

0.75x5=4.00

4.00+3.50=7.50

A taxi ride cost if Tamika is riding for 5 miles will be $7.25.

What is Linear function?

A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph.

Given, Tamika is ordering a taxi from an online taxi service. The taxi charges $3.50 just for the pickup and then an additional $0.75 per mile driven.

Let "m" be the miles Tamika is riding along.

Total additional charges = m *0.75

pick up charges = 3.50

So, Total charges Tamika has to pay for m miles = 0.75*m + 3.50

For m = 5 miles

Tamika has to pay for 5 miles = 0.75 * 5 + 3.50

Tamika has to pay for 5 miles = 7.25

Therefore, 7.25$ would a taxi ride cost if Tamika is riding for 5 miles.
