Answer: should be the top left one

Step-by-step explanation:

by plotting the points and trial and error

To evaluate if the athletes have improved in their flexibility, the physical therapist should run a paired t-test.

A paired t-test is appropriate in this scenario because the therapist is comparing the flexibility of the same group of athletes before and after the yoga training program. This test allows for the comparison of the mean flexibility scores within the same group, taking into account individual differences among the athletes.

Here's how the paired t-test works step-by-step:

1. First, the therapist would collect flexibility measurements from the 50 athletes before starting the yoga training program.
2. After the six-week program, the therapist would measure the athletes' flexibility again.
3. The therapist would then calculate the difference in flexibility scores for each athlete by subtracting the pre-training flexibility score from the post-training flexibility score.
4. Next, the therapist would calculate the mean difference in flexibility scores for the entire group.
5. The therapist would also calculate the standard deviation of the differences.
6. Using these calculated values, the therapist would perform the paired t-test to determine if there is a statistically significant difference in flexibility before and after the yoga training program.
7. The result of the t-test would provide a p-value, which indicates the probability of obtaining the observed difference in flexibility scores by chance alone.
8. If the p-value is below a predetermined significance level (typically 0.05), the therapist can conclude that the athletes' flexibility has improved significantly due to the yoga training program.

By running a paired t-test, the physical therapist can objectively evaluate whether the athletes have experienced a statistically significant improvement in their flexibility after participating in the six-week yoga training program.

The critical point of the function f(x) = 3x^2 is x = 0, and the function is decreasing on the interval (-∞, 0) and increasing on the interval (0, ∞). The first derivative test tells us that x = 0 is a local minimum.

To find the critical point(s) of the function, we need to find where its derivative is zero or undefined.

First, let's find the derivative of the given function:

f(x) = 3x^2

f'(x) = 6x

Setting f'(x) = 0, we get:

6x = 0

x = 0

Therefore, the critical point of the function is x = 0.

To determine whether the function is increasing or decreasing on either side of the critical point, we need to examine the sign of the derivative:

When x < 0, f'(x) < 0, so the function is decreasing.

When x > 0, f'(x) > 0, so the function is increasing.

Using the first derivative test, we can conclude that the critical point x = 0 is a local minimum. This is because the sign of the derivative changes from negative to positive at this point, indicating a change from decreasing to increasing

Answer:

The sum of 25 and 16 is 41.

Step-by-step explanation:

The sum of two numbers, 25 and 16, you can break apart the addends and add them separately to simplify the process. Here's how you can do it:

Break apart the numbers into their place values: For 25, you have 20 and 5, and for 16, you have 10 and 6. This step helps you work with the place values individually.

Add the tens place: In this case, you have 20 (from 25) and 10 (from 16). Adding them gives you 30.

Add the ones place: Now you add the ones place, which is 5 (from 25) and 6 (from 16). Adding them gives you 11.

Combine the sum of the tens place and the sum of the ones place: Take the sum of 30 (from step 2) and 11 (from step 3). Adding them together gives you 41.

So, the sun is 41.

Answer:

C

Step-by-step explanation:

To find (g ￮ f)(x), substitute x = f(x) into g(x) , that is

g(2x - 5)

= 3(2x - 5) + 4

= 6x - 15 + 4

= 6x - 11 → C

The interest rate is (1/3)(y*)² - 0.01 and the capital-output ratio is 50.

In the steady state, the output per worker, denoted as y*, is constant.

To find the steady state level of capital, denoted as K*, we can use the following equation:

sY* = (d + n + g)K*

where s is the saving rate, n is the population growth rate (assumed to be zero in this model), and g is the technological progress rate (also assumed to be zero).

Plugging in the values we have, we get:

0.5Y* = 0.01K*

Solving for K*, we get:

K* = 50Y*

Next, we can find the steady state output per worker, y*, by substituting K* into the production function:

y* = (K*/L)^(1/3) = \((50Y^*/L)^{1/3}\)

The interest rate is given by:

r = MPK - d

where MPK is the marginal product of capital, which represents the additional output that can be produced by adding one unit of capital. In this case, MPK is given by:

MPK = \((1/3)(Y^*/K^*)^{2/3}\) = (1/3)(y*)²

Plugging in the values we have, we get:

r = (1/3)(y*)² - 0.01

Finally, we can find the capital-output ratio, K/Y, by substituting K* and Y* into the equation:

K/Y = K*/Y* = 50

The probability that each bill drawn from Ben's wallet will be worth less than $10 is 2/21.

When Ben reaches into his wallet without looking and takes two bills out, we need to determine the probability that both bills will be worth less than $10.

To calculate this probability, we consider the total number of bills worth less than $10 in Ben's wallet, which is 5. The total number of bills in his wallet is 6, as there are two $20 bills, one $10 bill, and two $5 bills, in addition to the $1 bill.

For the first bill, the probability of selecting a bill worth less than $10 is 5/15, as there are 5 bills worth less than $10 out of the total 15 bills. After selecting the first bill, there are 14 bills left in the wallet.

For the second bill, the probability of selecting a bill worth less than $10 depends on the outcome of the first selection. Since one bill has already been drawn, there are now 4 bills worth less than $10 remaining out of the 14 bills in total.

To calculate the probability of both events occurring, we multiply the probabilities together: (5/15) * (4/14) = 2/21.

Answer:

A (-4,9) B (-4,11) C (-6,10)

Last option is correct

Step-by-step explanation:

To rotate the vertices about the given point at 90 degrees, we follow the procedures below;

Mathematically, if we have a point (m,n) and we want to rotate it 90 degrees about a given point (x,y). Then the new transformation point will be;

( -(n-y) + x , (m-x) + y)

Let’s now take the points individually;

(3,2 ) about (-4,2)

This becomes

(-(2-2) + (-4), (3+4) + 2) = (-4 , 9)

The point (5,2) about (-4,2) becomes

(-(2-2) + -4, (5 + 4) + 2 )= (-4, 11)

and lastly

The point (4,4) about (-4,2) becomes

(-(4-2) + (-4), (4 + 4) + 2) = (-6, 10)

Answer:

f(x) = 3x - 16

Step-by-step explanation:

y = 3x - 16 is a function in which y is a function of x.

To write it in function notation, we replace y with f(x). f(x) means that the function named f is a function of x. All you need to do is replace y with f(x).

f(x) = 3x - 16

Considering a meal cost of $75, we have that:

a) The price of the meal with the coupon is of: $60.

b) The final price, considering the tip, is of: $72.

The prices in this problem are found applying the proportions, multiplying the values by the decimal equivalent of the percentages.

The attributed cost is given as follows:

$75.

The family has a 20% off coupon, hence the price paid is 80% of the total price, which is obtained as follows:

Final price = 0.8 x 75 = $60.

The tip will be 20% of the price, hence it is calculated as follows:

Tip = 0.2 x 60 = $12.

Then the final price is obtained as the sum of the cost of the meal and the cost of the tip, as follows:

Final price = $60 + $12 = $72.
