Answer:

Birgetta Homan semimonthly salary is $ 1300.

Step-by-step explanation:

Given: Birgetta Homan is a medical assistant. Her annual salary is $31,200.

We have to calculate her semimonthly salary and choose the correct option from the given options.

Since, given her annual salary as $ 31,200

also we know 1 year has 12 months

So , her monthly salary can be find by dividing her annually salary by 12 .

that is \frac{31200}{12}=2600

Since, we have to calculate semi monthly that is she is paid twice a month so her semi-monthly salary will be \frac{2600}{2}=1300

Thus, Birgetta Homan semimonthly salary is $ 1300.

A number to the 12th power divided by the same number to the 9th power equals 125 what is the number
nadezda [96]

If x to the 12th power is divided by x to the 9th power:

Since they share same bases, and are being divided, it would be the same as x^{12 - 9), or x^{3}

Now, simply find the cube root of 125, which is 5.

Therefore, the number (x) must be equal to 5.

<em>Hope this helps! :)</em>

Find the x-intercept(s) of y = 2x2 - 3x - 5.<br> A) -5 <br> B) 2 1/2, -1<br> C) 3, -5 <br> D) 5, -1
Alexus [3.1K]

Answer:

\large\boxed{B)\ 2\frac{1}{2},\ -1}

Step-by-step explanation:

x-intercepts are for y = 0.

We have the equation:

y=2x^2-3x-5

Therefore

2x^2-3x-5=0\\\\2x^2+2x-5x-5=0\\\\2x(x+1)-5(x+1)=0\\\\(x+1)(2x-5)+0\iff x+1=0\ \vee\ 2x-5=0\\\\x+1=0\qquad\text{subtract 1 from both sides}\\\boxed{x=-1}\\\\2x-5=0\qquad\text{add 5 to both sides}\\2x=5\qquad\text{divide both sides by 2}\\\boxed{x=2\frac{1}{2}}

A marketing research company desires to know the mean consumption of milk per week among people over age 32. A sample of 440 peo
Softa [21]

Answer:

The 98% confidence interval for the mean consumption of milk among people over age 32 is between 3.3 and 3.5 liters.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1 - 0.98}{2} = 0.01

Now, we have to find z in the Ztable as such z has a pvalue of 1 - \alpha.

That is z with a pvalue of 1 - 0.01 = 0.99, so Z = 2.327.

Now, find the margin of error M as such

M = z\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 2.327\frac{0.8}{\sqrt{440}} = 0.1

The lower end of the interval is the sample mean subtracted by M. So it is 3.4 - 0.1 = 3.3 liters

The upper end of the interval is the sample mean added to M. So it is 3.4 + 0.1 = 3.5 liters

The 98% confidence interval for the mean consumption of milk among people over age 32 is between 3.3 and 3.5 liters.
