Jacob is traveling down a level roadway with a speed of 9.5 m/s. He slams on the breaks and encounters a coefficient of friction of 0.847. What distance does his 985 kg truck skid before stopping?

Answers

Answer 1

To find the distance that Jacob's truck skids before coming to a stop, we can use the formula for the distance traveled while braking, which is:

distance = initial velocity^2 / (2 * coefficient of friction * acceleration due to gravity)

In this case, the initial velocity is 9.5 m/s, the coefficient of friction is 0.847, and the acceleration due to gravity is 9.8 m/s^2. Plugging these values into the formula, we get:

distance = (9.5 m/s)^2 / (2 * 0.847 * 9.8 m/s^2)

Solving for distance, we get:

distance = 8.76 meters

Therefore, Jacob's truck will skid a distance of 8.76 meters before coming to a stop.

A conglomerate of Christmas tree growers in Oregon wants to know if there is a difference in preference for live Christmas trees between urban and rural regions of the state. They randomly surveyed 160 rural households that put up a Christmas tree the previous season and found that 64 had used a live tree. In a separate random survey, 89 of 261 urban household had put up a live tree the previous season. The 95% confidence interval for the difference of the true proportion of all households (rural - urban) in Oregon that preferred a live tree is between -0.036 and 0.154. Based on the confidence interval, is there convincing evidence that the two population proportions are different

Answers

Answer:

0 is part of the confidence interval, which means that there is not convincing evidence that the two population proportions are different.

Step-by-step explanation:

Based on a confidence interval for the difference of proportions, there will be significant evidence that the proportions are different if 0 is not part of the confidence interval for the difference of proportions.

In this question:

Confidence interval between -0.036 and 0.154

0 is part of the confidence interval, which means that there is not convincing evidence that the two population proportions are different.

order to win the game, and she wants to calculate her probability of winning.
Is the probability of Janessa winning an independent event or dependent event? Why?
O Her probability of winning a dependent event because it does not depend on the results of her
friends' rolls.
Her probability of winning is a dependent event because it depends on the results of her friends' rolls.

you walk into a store that is closing. the pants normally cost $60.00 but it is discounted 75% they are also taking additional 20% of what is the final price that you pay for the pants?

Answers

Answer:

The final cost of the pants is $ 12.

Step-by-step explanation:

Given that at a store that is closing the pants normally cost $ 60.00 but it is discounted 75%, and they are also taking an additional 20% off, to determine what is the final price for the pants, the following calculation must be performed:

100 - 20 = 80

(60 - (60 x 0.75)) x 0.80 = X

(60 - 45) x 0.80 = X

15 x 0.80 = X

12 = X

Thus, the final cost of the pants is $ 12.

Cos(x+y)cos(x-y)=cos^2y - sin^2x

Answers

cos(x + y) cos(x - y) = (cos(x) cos(y) - sin(x) sin(y)) (cos(x) cos(y) + sin(x) sin(y))

… = (cos(x) cos(y))² - sin(x) sin(y) cos(x) cos(y) + sin(x) sin(y) cos(x) cos(y) - (sin(x) sin(y))²

… = (cos(x) cos(y)) - (sin(x) sin(y))²

… = cos²(x) cos²(y) - sin²(x) sin²(y)

… = (1 - sin²(x)) cos²(y) - sin²(x) sin²(y)

… = cos²(y) - sin²(x) cos²(y) - sin²(x) sin²(y)

… = cos²(y) - sin²(x) (cos²(y) + sin²(y))

find the length of the third side of triangle if its midline measures 45cm​

Answers

Answer:

20 cm is the length of third side of triangle

Step-by-step explanation:

Length of 1st side = a

Length of 2nd side = 10cm = b

Length of 3rd side = 15cm = c

So,

Perimeter of triangle = 45 cm

a+b+c = 45cm

a + 10 + 15 = 45 cm

.'. a = 45-25 cm

= 20 cm

The midline or midsegment has a length equal to half of the third side.

Therefore, the length of the third side is 45 cm × 2 = 90 cm.

Response:

The length of the third side is 90 cm

Which theorem can be used to find the length of the third side?

Given:

The length of the midline = 45 cm

Required:

The length of the third side

Solution:

The midline is the line joining the midpoint of two sides of a triangle.

According to the midsegment theorem, the midline of a triangle is

parallel to the third side and has a length equal to half the length of the

third side.

Which gives;

The length of the mid line = [tex]\mathbf{\frac{1}{2}}[/tex] × The length of the third side

Let x represent the length of third side, we have;

45 = [tex]\frac{1}{2}[/tex] × x

Which gives;

The length of the third side, x = 2 × 45 cm = 90 cm

65 is what percent of 120?
(round to the nearest percent)

Answers

Answer:Lets say 60 is rounded to 60. So 60 is half of 120 , which means that the answer is a little bit more than 50% since 50x2=100%

So 50 plus the 5 we took away from the 60 in the beginning is 55%

I think your answer is 55%

Step-by-step explanation:

Your answer is 55%

The percentage of 65 out of 120 will be 54.167%.

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

The whole numbers are 65 and 120.

Then the percentage is written as,

P = (65 / 120) x 100

P = 0.54167 x 100

P = 54.167%

The percentage of 65 out of 120 will be 54.167%.
