Please helpppp!!! Find the area of the irregular figure

OverLord2011 [107]

Answer:

The area of the figure is 143 sq in

Step-by-step explanation:

10 in * 7 in = 70 sq in

12 in * 4 in = 48 sq in

5 in * 5 in = 25 sq in

A = 70 sq in + 48 sq in + 25 sq in

The monthly earnings of computer systems analysts are normally distributed with a mean of $4,300. If only 1.07% of the systems a

spin [16.1K]

Answer:800

Step-by-step explanation:

$Mean(\mu )=\$ 4300$

and $P(X>6140)=0.0107$

$P(X>x_0)=0.0107$

$P\left ( \frac{X-\mu }{\sigma}$

$P\left ( z$

$\frac{x-\mu }{\sigma}=InvNormal(0.9893)$

Using Z table to get InvNormal(0.9893)=2.30

$\frac{6140-4300}{\sigma}=2.30$

$\sigma =\frac{6140-4300}{2.30}=800$

Scores on a recent exam followed a normal distribution and letter grades will be assigned with 15% A, 35% B, 30% C, 15% D, and 5

noname [10]

Using the normal distribution, it is found that Sue will get a letter grade of B.

In a <em>normal distribution </em>with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

It measures how many standard deviations the measure is from the mean.
After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem, Sue got a grade of 0.85, hence $z = 0.85$ .

Looking at the z-table, z = 0.85 has a p-value of 0.8023, hence she is approximately in the top 20%, which is below the top 15% but above the top 50%, hence she got a letter grade of B.
