Answer:
2 because of the way the question is written
2/5 if you get 2 wrong.
Step-by-step explanation:
1/2 * 4/5 of means multiply
numerator: 1*4 = 4
denominator = 2 * 5 = 10
Answer: 4 / 10 but this will reduce. Divide Top and Bottom by 2
4/2 = 2
10/2 = 5
Answer: 2/5
The way you should answer is 2 because the question gives you the fact that it is in 5ths. If you get it wrong then put in 2/5.
Answer:
443.28
Step-by-step explanation:
Subtract 42.24 from 570.3 three times.
Answer:
2x + y = 5
y = 4x – 1
Substitute (2, 1) into system, then:
2x + y = 5 => 2 x 2 + 1 = 5 => 5 = 5 (satisfied)
y = 4x– 1 => 4 x 2 - 1 = 1 => -7 = 1 (not satisfied)
=> Option 3 is correct.
Hope this helps!

Answer:
Between 12.614 years and 16.386 years
Step-by-step explanation:
Given that:
Mean age (μ) = 14.5 years, standard deviation (σ) = 4.6 years, number o sample (n) and the confidence interval (c) = 90% = 0,9
α = 1 -c = 1 -0.9 = 0.1

The z score of
is the same as the z score of 0.45 (0.5 - 0.05). This can be gotten from the probability distribution table. Therefore:

The margin of error (e) =
= 
The interval = μ ± e = 14.5 ± 1.886 = (12.614 ,16.386)
He bought last year and year later total is $104.3
Each share he sold 62.80 with tax is 0.03
62.80x1.03= $64.684 for each share
So there are 40 shares
64.684 x 40= $2587.36
