Answer:
I don't think you are asking a math question, but in my opinion you should choose a leader that you think would be responsible in a group, then tell them what the group needs to do.
Step-by-step explanation:
Step-by-step explanation:
a=8cm
b=15cm
c=17cm
s=a+b+c/2
=8+15+17/2
=40/2
=20
Using heron's formula,
ar. of triangle= √s(s-a)(s-b)(s-c)
=√20(20-8)(20-15)(20-17)
=√20×12×5×3
=√2×2×5×2×2×3×5×3
=2×2×3×5
=60cm²
On side 17cm,
Ar. of triangle=1/2×b×h
60=1/2×17×h
∴h=60×2/17
=7.05 cm
Answer: 0.0944
Step-by-step explanation:
Given : Sample size of cars : n= 150, sample size is greater than 30 , so we use z-test.
Number of cars tested do have faulty catalytic converters =42
Then the proportion of cars have faulty catalytic converters : 
Critical value of z for 99% confidence level : 
Formula for Margin of error :


Hence, the required margin of error = 
To determine the expected number of sales after 3 years of a product, we need an equation that would relate time with the number of sales. In this case, we use the equation above which expresses the number of sales as a function of time. We simply substitute the time which would be 3 years to the equation and evaluate the value of N. We do as follows:
<span> N = 9200 ln (5t + 3)
</span><span> N = 9200 ln (5 ( 3 ) + 3)
</span><span> N = 9200 ln 18
N = 26591.42
Therefore, the correct answer would be option B. The number of sales after 3 years would be about 26591.</span>
Answer:
2x
Step-by-step explanation:
[8x² - 4x] ÷ [4x - 2]
[4x(x - 2)] ÷ [2(x - 2)]
[2x × 2(x - 2)] ÷ [2(x - 2)]
2x
