If you have 24 square pieces of wood, and you divided each in half. Then, you divided each of those in half. How many square pie

hichkok12 [17]

The answer is 96
24 pieces of wood all cut in half so multiply by 2
24x2=48
Now cut 48 pieces in half so multiply by 2
48x2=96

A study found that a large group of late lunch eaters lost less weight over a 20-week observation period than a large group of e

Vadim26 [7]

Answer:

Interpretation of P-value.

Step-by-step explanation:

P values helps us to evaluate and act as an indicator how well the sample data support the null hypothesis is true.
Thus, in a way it helps us to tell that the information obtained from the sample is true in respect to the population or not.
It measures how close the data are with respect to the null hypothesis.

High P-values means that the data supports the null hypothesis and sample provides correct information about the population.
A high p value states that the sample is taken from the population.

Low P-values means that the data does not supports the null hypothesis and sample does not provides correct information about the population.
A low p value states that the sample is not taken from the population.

A low P value suggests that the sample provides enough evidence and information, that we can reject the null hypothesis for the entire population or we can conclude that the sample does not belong to the population.

If p-value of 0.002 is less than the significance level than it provides enough evidence that we reject the null hypothesis.
Thus a low p value of 0.002 says that large group of late lunch eaters lost less weight than a large group of early lunch eaters.
Thus, this sample does not belong to the population where the loss in weight was same.

Have to bake a lot of brownies to sell! You have plenty of flour, cocoa, milk, and oil, but you only have 6 1/2 sticks of butter

Tems11 [23]

Answer: 8 + 2/3 batches of brownies you can bake.

Step-by-step explanation:

6 1/2 butter = 6 + 1/2 = (2·6 + 1)/2 = 13/2 sticks of butter, we have this

Since we have 13/2 sticks of butter and each batch of brownies needs 3/4 of a stick of butter, we have to divide the amount of butter we have between the amount of butter we use to bake a batch of brownies.

13/2 butter ÷ 3/4 butter/batch = 13·4/2·3 batches = 52/6 batches = 8 + 2/3 batches

Answer: 8 + 2/3 batches of brownies you can bake.

Find [g *h](x) and [h*g](x) . g(x) = 5x h(x) = –10x3 + 13x2 – 3x + 3

Llana [10]

Answer:

(g ο h)(x) = -50x³ + 65x² - 15x + 15

(h ο g)(x) = -1250x³ + 325x² - 15x + 3 ⇒ 3rd answer

Step-by-step explanation:

* Lets explain the composite function

- A composite function is a function that depends on another function

- A composite function is created when one function is substituted into

another function

- Example:

# (f ο g)(x) is the composite function that is formed when g(x) is

substituted for x in f(x).

* Now lets solve the problem

∵ g(x) = 5x

∵ h(x) = -10x³ + 13x² - 3x + 3

- To find (g ο h)(x) replace x in g by h(x)

∴ Replace x by -10x³ + 13x² - 3x + 3

∴ (g ο h)(x) = 5(-10x³ + 13x² - 3x + 3)

∴ (g ο h)(x) = -50x³ + 65x² - 15x + 15

- To find (h ο g)(x) replace each x in -10x³ + 13x² - 3x + 3 by g(x)

∴ Replace each x in -10x³ + 13x² - 3x + 3 by 5x

∴ (h ο g)(x) = -10(5x)³ + 13(5x)² - 3(5x) + 3)

∴ (h ο g)(x) = -10(125x³) + 13(25x²) - 15x + 3

∴ (h ο g)(x) = -1250x³ + 325x² - 15x + 3

* (g ο h)(x) = -50x³ + 65x² - 15x + 15

(h ο g)(x) = -1250x³ + 325x² - 15x + 3
