9. You have been saving your money to buy a new pair of shoes. Three different
stores are having a sale on them. Which store has the best deal? Order from
lowest price (top) to highest price (bottom).
A. Original Price $150 - Take $20 off. Then Take 10% off.
B. Sale Price $115
C. Original Price $160 - Take 10% off. Then take 20 $ off.

Answer:

100

Step-by-step explanation:

Because the 40 degree angle is an inscribed angle opposite of arc u, arc u's angle measure must be 40*2=80 degrees. Since t+u=180 degrees, t must be 100 degrees. Hope this helps!

Answer:

30 mm

Step-by-step explanation:

Formula: A = 1/2bh

Substitution: 240 = 1/2b • 16

Solving:

240 = 8b

240 = 8 • 30

b = 30 mm

Probability that a random sample of 15 bags will have a mean between 9 and 9.5 kgs is 0.0596.

\(\sigmaT = \sigma / \sqrtn = 1.25 / \sqrt15 = 0.3227\)

\(= P[(9 - 10) / 0.3227 < (T - \muT ) / \sigmaT < (9.5 - 10) / 0.3227)]\)

= P(-3.10 < Z < -1.55)

= P(Z < -1.55) - P(Z < -3.10)  

= 0.0606 - 0.001

=  0.0596

Probability that a random sample of 15 bags will have a mean between 9 and 9.5 kgs = 0.0596

csc(θ)= 12/7√2,tan(θ)= 12/7√2` is the value of csc(θ) and tan(θ).

Given, `sec(θ)= 7/11`To find:`csc(θ) and tan(θ)

`Formula used: `secθ = hypotenuse / adjacent`, `

cscθ = hypotenuse / opposite` and

`tanθ = opposite / adjacent`

We know that `sec(θ) = 7/11`

Let's draw a right-angle triangle to solve this problem,

In the given triangle, let `θ` be the acute angle, the hypotenuse is `11`, and the adjacent side is `7`.

Therefore, the opposite side will be `√(11² - 7²) = √(121-49) = √72

As we know, `cscθ = hypotenuse / opposite

Therefore, `cscθ = 11 / √72 = 11√72/72

To simplify the value of `cscθ`, we will multiply and divide `√2` in the denominator.

So, `cscθ = (11/72) * √72 * √2/√2 = 11√144/72√2` = `11/6√2

Also, `tanθ = opposite / adjacent`=`√72 / 7

To simplify the value of `tanθ`, we will multiply and divide `√2` in both numerator and denominator.

So, `tanθ = √72 * √2 / 7 * √2`=`√144 / 7√2` = `12/7√2

Hence, the correct answer is option `(e)` `csc(θ)= 12/7√2,tan(θ)= 12/7√2`.

The BMI of an 118-lb adult who is 5 feet 4 inches tall is approximately 20.25.

BMI stands for Body Mass Index.

It's a measure of body fat based on height and weight that applies to both adult men and women.

BMI is an easy-to-perform screening tool for body fat levels that can help identify individuals who have health risks linked with excess body fatness.

It's important to keep in mind that the BMI measurement should not be used as a diagnostic tool for health conditions and is only one component in an overall evaluation of a person's health status.

Using the formula below, we can calculate the BMI of an 118-lb adult who is 5 feet 4 inches tall: BMI = (weight in pounds / (height in inches x height in inches)) x 703

First, we need to convert the height into inches:5 feet 4 inches = 64 inches

Next, we plug the values into the formula and solve for the BMI:

BMI = (118 / (64 x 64)) x 703BMI = (118 / 4,096) x 703BMI = 0.0288 x 703BMI = 20.2464

Therefore, the BMI of an 118-lb adult who is 5 feet 4 inches tall is approximately 20.25.

The null hypothesis for the data will be 21.62 and the alternate hypothesis is 2.02 for the p-value for the data is 0.2253 .

The charge at which anything happens is referred to as the velocity at which it happens.

The required details for mean rate :

(a) H0: µ = 21.62

Ha: µ ≠ 21.62

(b) t = -1.231

p-value = 0.2253

(c) Stop rejecting H0 right now. No longer significantly different from the domestic water tariff in Tulsa, the suggested household water charge per five CCF for the entire USA.

(d) H0: µ = 21.62

Ha: µ ≠ 21.62

t = -1.231

check statistic ≥ 2.020

Don't dismiss H0 any longer. The suggested five CCF residential water charge for the entirety of the USA is no longer significantly different from the five CCF residential water tariff in Tulsa.

The P-value is higher at 0.05, the level of significance. The impact in this instance is negligible. The attempt to reject the null hypothesis failed.

The conclusion is that there is insufficient statistical support to determine whether other American cities have a different mortality rate than Tulsa.

The crucial values for t at this level of significance are t=2.019.

Given that the statistic t = -1.15 is inside the acceptance range in this case, the null hypothesis is not disproved.

\(\displaystyle \int(3t^3+30t^2+5)\,dt\\\\=\frac{3}{4}t^4+10t^3+5t+C\)

Plug-in initial condition to get C

Answer:

the slope is -1/4 throughout the line.

Step-by-step explanation:

the slope of a line never changes anywhere on the line. otherwise it would not be a line.

the slope is expressed by the ratio y/x indicating how many units y changes, when x changes by a certain number of units.

and in this graphic, when x changes 4 units to the right (positive), y changes 1 unit down (negative).

therefore -1/4

Answer:

3rd option

Step-by-step explanation:

The line has the same slope over the whole line

Calculate slope m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = O (0, 0) and (x₂, y₂ ) = B (- 12, 3)

m = \(\frac{3-0}{-12-0}\) = \(\frac{3}{-12}\) = - \(\frac{1}{4}\)

The slope is - \(\frac{1}{4}\) throughout the line

Carina needs to hit the ball at a height of about 3.04 feet to clear the net and land in the service box.

What is the trigonometric ratio?

There are six trigonometric ratios- sine(sin), cosine(cos), tangent(tan), cotangent(cot), secant(sec), cosecant(cosec). Let θ be the angle of the right-angled triangle then, sin θ = opposite side/hypotenuse or 1/cosθ.

To determine the height Carina needs to hit the ball to clear the net and land in the service box, we can use the following steps:

Draw a bird's-eye view diagram of the tennis court, including the net, the service box, and the path of the ball.

Draw a side view diagram of Carina and the ideal path of the tennis ball, including the measurements that are needed from the bird's-eye view diagram.

Use trigonometry to calculate the height Carina needs to hit the ball.

Determine whether it is reasonable for Carina to reach this height, given her height of 5'7".

Calculate the angle at which the ball hits the ground.

Here are the steps in more detail:

Bird's-eye view diagram:

We can draw a bird's-eye view diagram of the tennis court, with the net located at the center and the service box 21 feet away from the net. The distance from the net to the service box is (78-21)/2 = 28.5 feet. We can label the diagram with these distances and the height of the net (3 feet).

Side view diagram:

Next, we can draw a side view diagram that shows Carina, the ideal path of the tennis ball, and the measurements that are needed from the bird's-eye view diagram. We can label the diagram with the height of the tennis racket (h) and the distance from the racket to the net (x). We also need to label the height Carina needs to hit the ball to clear the net (y) and the height of the net (3 feet).

Calculate the height Carina needs to hit the ball:

To calculate the height Carina needs to hit the ball, we can use the following trigonometric formula:

tan(θ) = y / x

where theta is the angle between the ideal path of the ball and the ground, y is the height Carina needs to hit the ball, and x is the distance from the racket to the net.

Solving for y, we get:

y = x * tan(θ)

We know that x = 21 feet, and we can estimate that the angle theta is about 8 degrees (since the ball needs to clear the net by at least 3 feet). Plugging in these values, we get:

y = 21 * tan(8) = 3.04 feet

So Carina needs to hit the ball at a height of about 3.04 feet to clear the net and land in the service box.

Determine whether it is reasonable for Carina to reach this height:

Carina's height is 5'7", which is equivalent to 67 inches.

If we assume that Carina's arm reaches to about shoulder height, which is roughly halfway between her height and the height she needs to hit the ball (3.04 feet), then she would need to hit the ball about 1.5 feet above her shoulder.

This seems like a reasonable height for a skilled tennis player.

Calculate the angle at which the ball hits the ground:

To calculate the angle at which the ball hits the ground, we can use the following trigonometric formula:

tan(θ) = y / (x + d)

where d is the distance from the net to where the ball lands. We know that y = 3.04 feet, x = 21 feet, and d = 21 + 21 = 42 feet (since the ball travels the same distance on the other side of the court). Plugging in these values, we get:

tan(θ) = 3.04 / 42

θ = arctan(3.04 / 42)

θ = 0.07225

Hence, Carina needs to hit the ball at a height of about 3.04 feet to clear the net and land in the service box.
