Answer:
160g
Step-by-step explanation:
150 gr/100 =3/2
to find the sugar needed you inverse the fraction
240(2/3) =160
OR you can do cross multiplication
150--------------100
240---------------x
(240*100) / 150 x
24000/150 = 160
Or you can think that 150 i 100 plus half of 100 (100 + 50) = 150
and 240 is 160 plus half of 160 (160+80)=240

Since, r varies directly as s
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%.
