If he starts earning 40% more after he worked more than 30 hours and worked for 35 hours , that means that those 5 extra hours were worth 1.40(5) hours
Which is 7
So he earned what he would have earned if he had worked for 37 hours.
If he earned 436.60 in 35 hours ( which is equivalent to 37 normal hours )
he earns 436.60 ÷ 37 per hour

436.60 ÷ 37 = 11.8
Which means he normally earns $11.8 per hour !

I hope you understood my brief explanation
And please consider marking this as the Branliest awnser if you think it deserves! Thank you. :)

A company needs $5,400,000 in 14 years in order to expand their factory. How much should the company invest each week if the inv
ludmilkaskok [199]

Answer: the company should invest $12191 each week

Step-by-step explanation:

The amount that the company needs is $5,400,000

We would apply the periodic interest rate formula which is expressed as

P = a/[{(1+r)^n]-1}/{r(1+r)^n}]

Where

P represents the weekly payments.

a represents the amount that the company needs

r represents the rate.

n represents number of weekly payments. Therefore

a = 5,400000

There are 52 weeks in a year

r = 0.079/52 = 0.0015

n = 52 × 14 = 728

Therefore,

P = 5400000/[{(1+0.0015)^728]-1}/{0.0015(1+0.0015)^728}]

5400000/[{(1.0015)^728]-1}/{0.0015(1.0015)^728}]

P = 5400000/{2.98 -1}/[0.0015(2.98)]

P = 5400000/(1.98/0.00447)

P = 5400000/442.95

P = $12191

Because of a mistake in​ packaging, a case of 16 bottles of wine contained 9 of brand A and 7 of brand​ B, each without labels.
attashe74 [19]

Answer:

a) The probability that all five are brand​ A is 0.0288

b) The probability that exactly two bottles are brand​ A is 0.0288

c) The probability that none of the bottles is brand​ A is 0.0048

Step-by-step explanation:

We have 9 bottles of brand A and 7 bottles of brand B.

The total of bottles is 16.

a) The probability that all five bottles are brand​ A is given by:

P(5A)=\frac{9}{16} \frac{8}{15}\frac{7}{14}  \frac{6}{13} \frac{5}{12}=\frac{3}{104}=0.0288

b) Since we have 9 bottles of brand A we calculate the probability of picking two brand A bottles and the we calculate the probability of picking 3 brand B bottles:

P(2A3B)=\frac{9}{16} \frac{8}{15}\frac{7}{14}  \frac{6}{13} \frac{5}{12}=\frac{3}{104}=0.0288

c) The probability that none of the bottles is brand​ A is the same as picking 5 brand B bottles:

P(5B)=\frac{7}{16} \frac{6}{15}\frac{5}{14}  \frac{4}{13} \frac{3}{12}=\frac{1}{208}=0.0048
