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

A hypothesis test has a significance level of 10%. Explain what this significance level represents.
beks73 [17]
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.

Calculate answer a and c for this question​
Charra [1.4K]

Answer:

see explanation

Step-by-step explanation:

The area (A) of the whole sign is calculated as

A = \frac{1}{2} 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
