Answer: 0.6%
Step-by-step explanation:
We have a selection of 5 numbers, in those selection we have 3 combinations of 3 consecuitve numbers (because the numbers must be in correct order).
The first 3
The 3 in the middle
the last 3.
So a contestant has 3 combinations were he wins.
Now, the number of possible combinations of the 9 numbers given is:
For the first number we have 9 options.
For the second number we have 8 options (because we already selected one)
For the last number we have 7 options (because we already selected 2 numbers)
Then the number of possible combinations is
10*9*8 = 504
The probabilty of winning will be equal to the number of combinations that the contestant has (3) divided by the total number of combinations, this is:
p = 3/504 = 0.006 or 0.006*100% = 0.6%
It is 85 miles from central city to smithville and 125 miles from smithville to jonesburg. How many gallons of gas will it take to drive from central city to smithville to jonesburg in a car which gets 30 miles per gallon?
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:
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)
Which triangle is a translation of triangle X?
On a coordinate plane, triangle X is shifted 3 units down and 4 units to the left to form triangle B.
triangle A
triangle B
triangle C
triangle D
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.
A used car dealer sells SUVs and cars. Of all the vehicles, 90% are cars. Of all the vehicles 40% are red cars. What is the probability that a car chosen at random is red? Round your answer to the nearest tenth of a percent.
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.
Explanation: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:
26 square feet (no floor)38 square feet (with floor)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.

New home : 126 | 103 | 82 | 75 | 82 | 40 | 20
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:
Y = -0.79X + 249.86R = -0.9543What is Correlation Coefficient?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.

Find all of the solutions for the following equation. 2 sin q + 3 = sin q + 2
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
What’s the value of x?
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!

The cost of each ticket is $4.
How to find the price of each ticket?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

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.
