Answer:
Step-by-step explanation:
2(3x+4)=(2x3x)+(2x4)
2x(3x)=6x
2x4=8
6x+4=10x
Answer:
a: 0.6578
b: 0.6578
c: 0.6578
Step-by-step explanation:
For a: See attached photo 1 for the calculation of the probability
There is no more work needed to calculate the other probabilities. The mean is the only thing that's different. We still want a range of being within 10 points of the population mean, so the z-scores won't change, even though the mean has. We would still wind up with the same numerator in the test statistic, and since the sample size didn't change, we'd get the same z-value!
First since it is a triangle and it says meter square that means its an area
so the area is 1/2hb h stands for height and b stands for base
so
a=1/2bh
a=1/2(12)(9)
a=1/2(108)
a=54m^2
It says the cost of sail is $15 per square meter
so
$15*54
=$810
Why times by 54 because if 1 piece is $15 how about 54pcs?
thats why we will multiply it
