Find the area under the standard normal curve to the right of z=1.9

1 answer:

6 0

To find the area to the right of a positive z-score, begin by reading off the area in the standard normal distribution table. Since the total area under the bell curve is 1, we subtract the area from the table from 1. For example, the area to the left of z = 1.02 is given in the table as .846.

If the average (arithmetic mean) of 2,7, and x is 12, what is the value of x

guajiro [1.7K]

x is equal to 27.

In order to find the value of x, you have to use the average formula and solve for the missing variable. The mean formula is all of the numbers added together divided by the number of inputs.

(inputs added)/(number of inputs) = Average

(2 + 7 + x)/3 = 12 ----> Multiply by 3

9 + x = 36 ----> Subtract 9

x = 27

You just received an insurance settlement offer related to an accident you had six years ago. The offer gives you a choice of on

Usimov [2.4K]

answer:

Step-by-step explanation:

Option A. $1565 for 72months

Then the total is $112,680

Option B. $1012 for a month for 10 years,

10years is equivalent to 120months

Therefore, the total income is 1012×120

$121,440.

Option 3.

$100,000 once payment.

All the information is correct.

But,

Since the individual did not care if he receives the fund or it is transfer to his heir, so we can ignore the third option of collecting $100000 lump sum.

Also, since he is also ready to wait and he is indifferent about who earns the insurance settlement so he can as well wait and ignore the 72months.

So he can go for the second option because it pays the largest amount and he will receive the most payments.

He will receive $121,440 if he waits for ten years.

Whole numbers are written on cards and then placed in a bag. Pilar selects a single card, writes down the number, and then place

tatuchka [14]

Answer:

The answer is A (i just took the test)

Step-by-step explanation:

Answer: The outcomes do not appear to be equally likely, so a uniform probability model is not a good model to represent probabilities in Pilar's experiment

The outcomes are: 1 2 3 4 5

The Relative Frequency: 0.05 0.35 0.26 0.13 0.21

As you can see the outcomes do not appear to be equally likely since 0.05 and 1 are not close in number range along with the other options
