The question wants to determine BOTH at an amount of time.
Green lawn: 28x2=46+42=98 | 28x3=84+42=126
|
These are incorrect | These are correct
Yard guard: 34x2=68+ 24=92 | 34x3=102+24=126
So then 3 months and 126 dollars
In statistical methods, the significance level is a value that is used as a criterion for rejecting a null hypothesis. It used by first looking at the differences between the experimental results and from there the null hypothesis would be determined. Then, we assume that the null hypothesis is true, the probability of the differences is computed by using statistical tools. If the computed probability is less than or equal to the value of the significance level, then you conclude that the null hypothesis should be rejected and that the results are statistically significant. Usually, a significance level of 1% or 5% is used.
This should be what you need, sorry for the wonky lines.
Answer:
see explanation
Step-by-step explanation:
The area (A) of the whole sign is calculated as
A = 
bh ( b is the base and h the height )
Here b = 40 and h = 35, thus
A = 0.5 × 40 × 35 = 20 × 35 = 700 cm²
The area of the inner triangle is calculate as
A = 0.5 × 32 × 28 = 16 × 28 = 448 cm²
The area of the border is the difference between the whole sign and the inner triangle, that is
area of border = 700 - 44 8 = 252 cm²
