Geometry Help. Justify or prove these two triangles are similar, show all calculations and support using mathematical reasoning, theorems, or definitions.

Step-by-step explanation:

1. the hawker claims that the average weight of each Apple sold by him is 50 grams. Now, to understand whether the claim is true, we will carry out hypothesis test.

(1) What should be the hypothesis of nihility and opposition?

(2) Set the significant level of 0.05, we decided to randomly select 100 apples for examination, so what is the selection of the test statistics（ Including use conditions and sampling distribution)

(3) Why reject domain?

(4) If the average weight of 100 apples randomly selected is 48.5g and the standard deviation is 7.5G, what is the statistical value of the verification?

(5) What are the results and conclusions of the verification?

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
