Answer:

sin A  = 40/41

tan A = 40/9

cos A = 9/41

Step-by-step explanation:

sin theta = opp/ hyp

tan theta = opp/ adj

cos theta = adj/ hyp

We want to find the measures for angle A

sin A  = 40/41

tan A = 40/9

cos A = 9/41

Answer:

SinA = opposite/hypotenuse

SinA = 40/41

SinA = 0.976

(0.9756097561)

TanA = opposite/adjacent

TanA = 40/9

TanA = 4.444

(4.44444444)

CosA = adjacent/hypotenuse

CosA = 9/41

CosA = 0.220

(0.2195121951)

Step-by-step explanation:

I did -9×2.2 on my calculator

It will take 7 gallons of gas to drive from Central City to Smithville to Jonesburg in a car that gets 30 miles per gallon.

To calculate the total amount of gas needed to drive from Central City to Smithville to Jonesburg, we need to add up the distances for each leg of the trip and then divide by the car's mileage per gallon.

Central City to Smithville: 85 miles

Smithville to Jonesburg: 125 miles

Total distance: 85 + 125 = 210 miles

Given the car gets 30 miles per gallon, divide total distance by mileage per gallon:

Total gallons of gas needed = 210 miles ÷ 30 MPG = 7 gallons

Therefore, it will take 7 gallons of gas to drive from Central City to Smithville to Jonesburg in a car that gets 30 miles per gallon.

Answer:

44.4%

Step-by-step explanation:

To calculate this, we proceed as follows.

we use the probability equation below;

P(A|B) = P(A and B) / P(B)

Applying the above to the scenario at hand;

P(red | car) = P(red and car) / P(car)

P(red and car) = 40% or simply 40/100 = 0.4

P(car) = 90% = 90/100 = 0.9

P(red | car) = 0.4/0.9

P(red | car) = 0.4444 which is = 44.44% ; to the nearest tenth of a percent = 44.4%

To find the probability of a randomly chosen car being red, you divide the percentage of red cars by the percentage of all cars. The calculation results in 44.4%, which is the probability that a car is red.

To find the probability that a car chosen at random is red, we use the information provided: 90% of all vehicles are cars, and 40% of all vehicles are red cars. To determine the probability of a randomly selected car being red, we must calculate the percentage of red cars within the group of all cars.

This is done by dividing the percentage of red cars by the percentage of all cars, which gives us the probability that a car, given it's a car, is red.

The calculation is (40% / 90%) × 100, which simplifies to 44.4%. Rounded to the nearest tenth of a percent, the probability is 44.4%.

Answer:

x = [tex]i\sqrt{55} , -i\sqrt{55}[/tex]

Step-by-step explanation:

x^2 + 8^2 = 9

Simplify the 8^2

x^2 + 64 = 9

Subtract 64 from both sides

x^2 = -55

Take the square root from both sides

x = +/- [tex]\sqrt{-55}[/tex]

Simplify

x = [tex]i\sqrt{55} , -i\sqrt{55}[/tex]

Hope this helps!

Final answer:

Triangle B is the translation of triangle X as it is moved 3 units down and 4 units to the left.

Explanation:

The question involves finding a triangle that is a translation of another triangle on a coordinate plane. A translation in geometric terms means moving a shape in the plane without rotating or resizing it.

According to the given information, triangle X is translated 3 units down and 4 units to the left to form triangle B.

Based on this information, triangle B is the translated figure of triangle X, and thus it is the correct answer.

Answer:

q = 270 degrees + 360n  where n is an integer

Step-by-step explanation:

2 sin q + 3 = sin q + 2

Subtract sin q from each side

2 sin q - sin q + 3 = sin q + 2

sin q + 3 = 2

Subtract 3 from each side

sin q +3-3 = 2-3

sin q = -1

Take the inverse sin of each side

sin ^-1 (sin q) = sin^-1 (-1)

q = 270 degrees + 360n  where n is an integer

Answer:

65 square inches.

Step-by-step explanation:

To solve for this irregular figure, you must break it into separate rectangles.

Firstly, we can solve for the area of the top rectangle by:

6×4= 24 sq in.

For the next rectangle, we can do:

4×8= 32 sq in.

Finally, the remaining square can be solved by:

3×3= 9 sq in.

To get the ENTIRE area, you will need to add these areas up which gets you:

24+ 32+ 9= 65 sq in.

Answer:

150 degrees

Step-by-step explanation:

Let's call the angle in the triangle next to the 78 A, the one next to the 132 B, and the one next to the x C. You know that the measure of angle A is 180-78=102 because they are linear pairs. Similarly, the measure of angle B is 180-132=48 degrees. Because all of the angles in a triangle must add up to 180 degrees, C must be 180-102-48=30 degrees. Finally, since x and C are linear pairs, x's angle measure must be 180-30=150 degrees. Hope this helps!

Answer:

The cost of each ticket is $4.

Here we know that the family buys 6 tickets, and they also pay $3 for a parking fee.

The total amount that they spend is $27.

If we remove what the paid for the parking fee, we only will have the cost of the 6 tickets, then we have:

$27 - $3 = $24

Now, we divide this by the number of tickets bought:

$24/6 = $4

Each ticket costs $4.

A.) state the linear regression function that estimates the number of new homes available at a specific price.

B.) state the correlation Coefficient of the data, and explain what it means in the context of the problem

Answer:

Y = -0.79X + 249.86

R = -0.9543

Step-by-step explanation:

Sale Price :160 | 180 | 200 | 220 | 240 | 260 | 280

New home     : 126 | 103 | 82 | 75 | 82 | 40 | 20

Calculate the Linear regression equation :

Using the linear regression calculator :

The linear regression equation is :

Y = -0.79X + 249.86

The correlation Coefficient 'R' measures the strength of statistical relationship between the relative movement of two variables. The The value of R is -0.9543 in the question above.

This is a strong negative correlation, which means that high sales price of homes scores correlates with low number of new homes  scores (and vice versa). Homes with high sales price have fewer number of new homes.

The correct answer to the given table based on the linear regression is:

This refers to the number between -1 and +1 where the interdependence of two variables are shown.

Hence, based on the given table:

Sale Price :160 | 180 | 200 | 220 | 240 | 260 | 280

New home    : 126 | 103 | 82 | 75 | 82 | 40 | 20

To find the Linear regression equation :

Y = -0.79X + 249.86

R= -0.9543

Hence, we can see that the correlation coefficient "R" is used to show the statistical relationship between the two variables.

As a result of the strong negative correlation, then there would be higher prices for homes and lower number of new homes.

Answer:

Step-by-step explanation:

The triangular end of the tent has a base of 3 ft and a height of 2 ft. Its area can be found using the formula for the area of a triangle:

  A = (1/2)bh

  A = (1/2)(3 ft)(2 ft) = 3 ft^2

__

The rectangular side of the tent has a length of 4 ft and a width of 2.5 ft. Its area can be found using the formula for the area of a rectangle:

  A = lw

  A = (4 ft)(2.5 ft) = 10 ft^2

___

If we assume the tentmaker makes the two sides not shown exactly the same as these, then the total above-ground material will be ...

  2(3 ft^2 +10 ft^2) = 26 ft^2

If there is on-ground material (a floor), that rectangle adds (3 ft)(4 ft) = 12 ft^2 to the total.

The area of the tent above-ground is 26 square feet. With a floor, it is 38 square feet.
