Sam sold half as many as Odel.
That means Odel sold twice as many as Sam.

Let x = number of pizzas sold by Sam.
Then Odel sold 2x.
Altogether they sold 126

x + 2x = 126

3x = 126

x = 42

Since x is the number of pizzas sold by Sam, that is our answer.

Answer: Sam sold 42 pizzas.

. According to Management Accounting, salary figures for certified management accountants (CMAs) who are in the field less than

Answer:

The Mean is not equal to $31,129.

Step-by-step explanation:

Consider the provided information.

The mean is $31129

Thus, the null hypothesis $H_0: \mu = 31129$

Alternative hypothesis $H_a: \mu \neq 31129$

A random sample of 15 firstyear CMAs in Denver produces a mean salary of $32,279, with a standard deviation of $1,797.

Thus the value mean of sample is 32279, standard deviation is 1797 and number of samples are 15.

Now use the 2 sided t-test.

$t=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

Now substitute the respective values in the above formula.

$t=\frac{32279-31129}{\frac{1797}{\sqrt{15}}}$

$t=\frac{1150}{464}$

Test Value = 2.4785 approximately

Now, find the corresponding p-value in your t-table with DF(degree of freedom) 14.

p = 0.0265

as the value of p < 0.05, so you reject null hypothesis.

Thus, the Mean is not equal to $31,129.

If the diagonal path is 750 feet long and the width of the park is 450 feet, what is the length, in the feet, of the park?

torisob [31]

Answer:

The length is 600 ft

Step-by-step explanation:

We can solve this by applying the Pythagorean theorem

a^2 + b^2 = c^2

The hypotenuse (diagonal path) is 750

750 represents c, 750^2 is 562500

We also know the width (one side of the triangle)

450 can represent a, 450^2 is 202500

202500 + b^2= 562500

We can subtract 202500 on both sides to isolate the b^2

b^2= 360000

Square root both sides of the equation

B= 600

The length is 600 ft
