Martin ordered a pizza with a 12-inch diameter. Ricky ordered a pizza with a 16-inch diameter. What is the approximate differenc
adell [148]

Answer:

88 in²

Step-by-step explanation:

The shape of a pizza = Circular

Area of a circle = πr²

For Martin

Martin ordered a pizza with a 12-inch diameter.

Radius = Diameter/2 = 12 inch/2 = 6 inch

Area of Martin's pizza = π × 6²

= 113.09733553 in²

≈ 113.1 in²

For Ricky

Ricky ordered a pizza with a 16-inch diameter.

Radius = Diameter/2 = 16 inch/2 = 8 inch

Area of Martin's pizza = π × 8²

= 201.06192983in²

= 201.1in²

The approximate difference in area of the two pizzas in square inches is calculated as:

201.1 in² - 113.1 in²

= 88 in²

G(x) = 3x + 1<br><br>f(x) = 2x - 5<br><br> Find g (f (x))​
sammy [17]

Answer:

g(f(x)) = 6x - 14

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Distributive Property

<u>Algebra I</u>

  • Function Composition

Step-by-step explanation:

<u>Step 1: Define</u>

g(x) = 3x + 1

f(x) = 2x - 5

<u>Step 2: Find</u>

  1. Substitute:                    g(f(x)) = 3(2x - 5) + 1
  2. Distribute 3:                  g(f(x)) = 6x - 15 + 1
  3. Combine like terms:    g(f(x)) = 6x - 14

A simple random sample of size nequals15 is drawn from a population that is normally distributed. The sample mean is found to be
Bond [772]

Answer with explanation:

To test the Significance of the population which is Normally Distributed we will use the following Formula Called Z test

   z=\frac{\Bar X - \mu}{\frac{\sigma}{n}}

\Bar X =31.1\\\\ \sigma=6.3\\\\ \mu=25\\\\n=15\\\\z=\frac{31.1-25}{\frac{6.3}{\sqrt{15}}}\\\\z=\frac{6.1\times\sqrt{15}}{6.3}\\\\z=\frac{6.1 \times 3.88}{6.3}\\\\z=3.756

→p(Probability) Value when ,z=3.756 is equal to= 0.99992=0.9999

⇒Significance Level (α)=0.01

We will do Hypothesis testing to check whether population mean is different from 25 at the alpha equals 0.01 level of significance.

→0.9999 > 0.01

→p value > α

With a z value of 3.75, it is only 3.75% chance that ,mean will be different from 25.

So,we conclude that results are not significant.So,at 0.01 level of significance population mean will not be different from 25.
