In an article about the cost of health care, USA Today reported that a visit to a hospital emergency room has a mean cost of $14

Misha Larkins [42]

Answer: 0.8461

Step-by-step explanation:

Given : $\mu=144\ \ ; \sigma=392$

Let x be the random variable that represents the cost for the hospital emergency room visit.

We assume that cost for the hospital emergency room visit is normally distributed .

z-score for x=1000 ,

$z=\dfrac{1000-1400}{392}\approx-1.02\ \ \ [\because z=\dfrac{x-\mu}{\sigma}]$

Using z-value table , we have

P-value =P(x>1000)=P(z>-1.02)=1-P(z≤ -1.02)=1-0.1538642

=0.8461358≈0.8461 [Rounded nearest 4 decimal places]

Hence, the probability that the cost will be more than $1000 = 0.8461

6/10+6/100= how do i do this problem

olya-2409 [2.1K]

Answer:

0.66

Step-by-step explanation:

As division is always done before addition you would divide the 6 by 10 and then divide the 6 by 100. 6 divided by 10 is equal to 0.6 as you move the decimal point to the left once. 6 divided by 100 is equal to 0.06 as you move the decimal point to the left twice. Addition is always done after division so you would add 0.6 and 0.06 together. This will give you 0.66 as your answer.

What is the future value of a R 75 000 deposit made every 6 months for 3 years using an annual rate of 10% compounded semi-annua

dolphi86 [110]

Answer:

The future value is: RS 132867.075

Step-by-step explanation:

Given

$PV = 75000$ --- present value

$r = 10\%$ --- annual rate

$n = 6$ --- number of times compounded (3 years/ 6 months)

Required

The future value

This is calculated as:

$FV =PV * (1 + r)^n$

$FV = 75000 * (1 + 10\%)^6$

$FV = 75000 * (1 + 0.10)^6$

$FV = 75000 * (1.10)^6$

$FV = 132867.075$

Hence, the future value is: RS 132867.075

question is ,four children saved £29 to go on a coach. They each saved the same amount. How much did each saved

Andreas93 [3]

If they saved £29 all together, and if each of them saved the same amount,
then each saved £29/4 = £7.25 or £7 and 25p.

(Before decimalization in 1971, £7.25 would have been £7 and 5s .)
