Q # 9 ease help to solve

shtirl [24]

The third choice - 65.3%.

He made 66 successful attempts out of 101 total free throws. To find the experimental probability, it will be 66 divided by 101.

66 successful / 101 total attempts = 0.6534

Rounded off to the nearest tenth of a percent - 65.3%
The experimental probability that you make a free throw is 65.3%.

Answer: see proof below

<u>Step-by-step explanation:</u>

Given: cos 330 = $\frac{\sqrt3}{2}$

Use the Double-Angle Identity: cos 2A = 2 cos² A - 1

$\text{Scratchwork:}\quad \bigg(\dfrac{\sqrt3 + 2}{2\sqrt2}\bigg)^2 = \dfrac{2\sqrt3 + 4}{8}$

Proof LHS → RHS:

LHS cos 165

Double-Angle: cos (2 · 165) = 2 cos² 165 - 1

⇒ cos 330 = 2 cos² 165 - 1

⇒ 2 cos² 165 = cos 330 + 1

Given: $2 \cos^2 165 = \dfrac{\sqrt3}{2} + 1$

$\rightarrow 2 \cos^2 165 = \dfrac{\sqrt3}{2} + \dfrac{2}{2}$

Divide by 2: $\cos^2 165 = \dfrac{\sqrt3+2}{4}$

$\rightarrow \cos^2 165 = \bigg(\dfrac{2}{2}\bigg)\dfrac{\sqrt3+2}{4}$

$\rightarrow \cos^2 165 = \dfrac{2\sqrt3+4}{8}$

Square root: $\sqrt{\cos^2 165} = \sqrt{\dfrac{4+2\sqrt3}{8}}$

Scratchwork: $\cos^2 165 = \bigg(\dfrac{\sqrt3+1}{2\sqrt2}\bigg)^2$

$\rightarrow \cos 165 = \pm \dfrac{\sqrt3+1}{2\sqrt2}$

Since cos 165 is in the 2nd Quadrant, the sign is NEGATIVE

$\rightarrow \cos 165 = - \dfrac{\sqrt3+1}{2\sqrt2}$

LHS = RHS $\checkmark$

Snowboarders use angle measures to describe their flips and spin explain what a snowboarder would mean by each statement? plz he

lidiya [134]

If you spin on the spot and go completely around just once and stop, you "did a 360" since you moved in a circle and circles have 360 degrees.

So a 720 would be two complete turns and a 540 would be 1 and a half complete turns.

The number is <em>the amount of degrees they rotated through</em>. What's cool is, snow boarders do this while in mid air as a trick when going over jumps.
