$\sin^2\alpha-\cos^2\alpha=2\sin^2\alpha-1\\\sin^2\alpha+\cos^2\alpha=1$

This is the Pythagorean identity, therefore $\alpha\in\mathbb{R}$ .

56 + 96 = 152

The factors of 152 are:

1, 2, 4, 8, 19, 38, 76, 152

We need to rewrite 152 as 2 factors, one of them is 8.

The other is the sum of 2 numbers that do not have a common factor.

The other factor is 19 because it is the sum of 10 and 9.

152 = 8 × 19

A spinner has three sections. The table shows the results of spinning the arrow on the spinner 80 times. What is the experimenta

mihalych1998 [28]

The experimental probability is

(number of times it stopped over Sect. 2) / (total number of times you tried it)

Number of times it stopped in Section-2: 36

Total number of times you tried it: (20 + 36 + 24) = 80

Experimental probability of Section-2 = 36/80 = 9/20 = 45%
