Answer:
Cornor has $14.17 initially
Step-by-step explanation:
The complete question is as follows
Connor has five times as much money as Jayden. Connor gives some money to Jayden. They now have £8.520each. How much did Connor have at the start?
solution
In this question, we are concerned with knowing how much that both had initially.
Let the amount of money Jayden has be £x . Since Cornor has Five times this, he has £5x
Let the amount of money Cornor gave Jayden be £y.
This means ;
5x - y = 8.50 .....(
(i)and also x + y = 8.50 ......(ii)
It is this equations we solve simultaneously
From i, we can say let y= 5x - 8.50, and we insert this into equation ii
x + 5x - 8.50 = 8.50
6x = 17
x = 17/6
x = $2.83
y = 5x - 8.50
y = 5(2.83) - 8.50
y = $5.67
The amount of money Cornor has at first is 5x = 5(17/6)
5x = $14.17

a. What percent of people earn less than $40000?
Solution: Let S be the random variable of a salary of employee (in $), S ~ N(50000,20000). Then the random
variable X =−50000
20000
~N(0,1).
( < 40000) = ( <
40000 − 50000
20000 ) = ( < −0.5) = (−0.5) = 0.3085375.
Here Φ(x) denotes the cumulative distribution function of a standard normal distribution.
Answer: 31%.
b. What percent of people earn between $45000 and $65000?
Solution:
(45000 < < 65000) = (
45000 − 50000
20000 < <
65000 − 50000
20000 ) = (−0.25 < < 0.75)
= (0.75) − (−0.25) = 0.7733726 − 0.4012937 = 0.3720789.
Answer: 37%.
c. What percent of people earn more than $70000?
Solution:
( > 70000) = ( >
70000 − 50000
20000 ) = ( > 1) = 0.8413447.
Answer: 84%.
Answer:
Step-by-step explanation:
126 mi/h = (126 mi)/(1 h)·(5280 ft)/(1 mi)·(1 h)/(3600 s) = (126·5280/3600) ft/s
126 mi/h = 184.8 ft/s = 924/5 ft/s
__
In 2 seconds, the parachutist falls ...
(184.8 ft/s)·(2 s) = 369.6 ft
