The type of study which is sports medicine doctor is using on the adult athletes for the placebo soft drink is experiment.

Statistical study is used to obtain the data and examine this data in the way, that its effectiveness can be measured.

There are three main types of statistical study-

It is given that a sports medicine doctor is interested in comparing the effectiveness of a new sports drink for adult athletes.

For this, the doctor randomly assigns a group of 80 adult athletes into 2 equal groups of 40-40 each.

Now, one group is given the new sports drink, while the other is given a placebo.Here, the medicine doctor is directly giving the sport drink to a set of sample.

By this he will, see the effectiveness of the group which are given placebo drink compare to the other group, which are not given this drink.

Thus, type of study which is sports medicine doctor is using on the adult athletes for the placebo soft drink is experiment.

Using the normal distribution, it is found that P(5 ≤ x ≤ 17) = 0.6247.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, we are given that [tex]\mu = 8, \sigma = 6[/tex].

The probability is the p-value of Z when X = 17 subtracted by the p-value of Z when X = 5, hence:

X = 17:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{17 - 8}{6}[/tex]

[tex]Z = 1.5[/tex]

[tex]Z = 1.5[/tex] has a p-value of 0.9332.

X = 5:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{5 - 8}{6}[/tex]

[tex]Z = -0.5[/tex]

[tex]Z = -0.5[/tex] has a p-value of 0.3085.

0.9332 - 0.3085 = 0.6247.

Hence, P(5 ≤ x ≤ 17) = 0.6247.

Considering that both Chicago and Memphis are in the same time zone, the flight took one hour and 40 minutes.

It Chicago at 9:50 AM Central Time and arrived in Memphis at 11:30 AM Central Time. Since they are in the same time zone, we don't have to do anything but subtract, then:

11:30 - 9:50

30 < 50, hence we remove one hour from Memphis and add 60 minutes, thus:

10:90 - 9:50 = 1:40

The flight took one hour and 40 minutes.

Answer:

We can first determine it is not A or C, because these flatly do not equal the expression above.

I believe is it D, because of the commutative property.

The associative property of addition states that you can group the addends in different ways without changing the outcome. While the commutative property of addition states that you can reorder the addends without changing the outcome.

In this case, we are rearranging the addends, not groups of them.

Answer:

C

Step-by-step explanation:

Let's set up a simultaneously equation to solve for two unknows.

Let x be the cost of cheese pizza

Let y be the cost of mushroom pizza

"Jack bought 3 slices of pizza and 4 slices f mushroom pizza for a total cost of $12.50."

Therefore,

3x + 4y = 12.50 (Equation 1)

"Grace bought 3 slices of cheese pizza and 2 slices of mushroom pizza for a total cost of 8.50."

Therefore,

3x + 2y = 8.5 (Equation 2)

From equation 1, let's solve for x in terms of y

3x + 4y = 12.50

3x = 12.50 - 4y

[tex]y = \frac{12.50-4y}{3}[/tex]

Plug in this y value into equation 2, we have:

[tex]3(\frac{12.50-4y}{3}) + 2y = 8.5[/tex]

We will get that y = 2

Hence, option C is the answer.

Answer:

-17 (I believe)

Step-by-step explanation:

If x = 64 then the first one is asking for the square root of 64 (8)

With y being 25 the second part of this problem is actually really easy, all its doing is getting the square root and then squaring it (doing nothing at all) so that would just be 25 which would make it

8-25 which would be -17
