A tree planted today has a height of 5 feet and grows one foot each month.

Solve for x, the figure is a parallelogram. will give brainliest, pls show work !!

MakcuM [25]

Answer:

x = 7

Step-by-step explanation:

In a parallelogram the opposite angles are congruent, then

14x + 8 = 106 ( subtract 8 from both sides )

14x = 98 ( divide both sides by 14 )

x = 7

Sally Jones pays $50.00 a month for group health insurance. There is a $300 deductible. Her medical bills for the last year were

neonofarm [45]

Given

Find out the what was the insurance company's payment .

To proof

As given

Sally Jones pays $50.00 a month for group health insurance

There is a $300 deductible

Her medical bills for the last year were $2,600.00

Linda's insurance company provided payment of 80% of the bills less the deductible.

Deductible

The amount of money you will pay in an insurance claim before the insurance company starts paying you.

medical bill reducing the deductible = $2,600 - $300

= $2300

80 % is written in the decimal form

$= \frac{80}{100}$

= 0.8

than the equation becomes

Linda's insurance company provided payment = 0.8× 2300

= $1840

Therefore the the insurance company's payment be $1840 .

Hence proved

Bones Brothers & Associates prepare individual tax returns. Over prior years, Bones Brothers have maintained careful records

madreJ [45]

Answer:

For this case we have the following info related to the time to prepare a return

$\mu =90 , \sigma =14$

And we select a sample size =49>30 and we are interested in determine the standard deviation for the sample mean. From the central limit theorem we know that the distribution for the sample mean $\bar X$ is given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

And the standard deviation would be:

$\sigma_{\bar X} =\frac{14}{\sqrt{49}}= 2$

And the best answer would be

b. 2 minutes

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The central limit theorem states that "if we have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large".

Solution to the problem

For this case we have the following info related to the time to prepare a return

$\mu =90 , \sigma =14$

And we select a sample size =49>30 and we are interested in determine the standard deviation for the sample mean. From the central limit theorem we know that the distribution for the sample mean $\bar X$ is given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$
