Use the power-reducing formulas to rewrite the expression as an equivalent expression that does not contain powers of trigonome

ratelena [41]

Answer:

$x = 0.175\cdot (1-\cos 4\cdot \theta)$

Step-by-step explanation:

Let use the following trigonometric identities:

$\sin^{2}\theta = \frac{1-\cos 2\cdot \theta}{2} \\\cos^{2}\theta = \frac{1+\cos 2\cdot \theta}{2}$

Then, the equation is simplified by substituting its components:

$x = 1.40\cdot \left(\frac{1-\cos 2\cdot \theta}{2} \right)\cdot \left(\frac{1+\cos 2\cdot \theta}{2} \right)$

$x = 0.35\cdot (1-\cos^{2}2\cdot \theta)$

$x = 0.35\cdot \sin^{2}2\cdot \theta$

$x = 0.35\cdot \left(\frac{1-\cos 4\cdot \theta}{2} \right)$

$x = 0.175\cdot (1-\cos 4\cdot \theta)$

Answer:

B. The probability that the student received a grade better than C is 0.45

Step-by-step explanation:

<u>Total number of students:</u>

15 + 30 + 35 + 16 + 4 = 100

<h3>Statements</h3>

p(<D) = 4/100 = 0.04
0.04 ≠ 0.2
Incorrect

p(>C) = (30 + 15)/100 = 45/100 = 0.45
0.45 = 0.45
Correct

p(not A or B) = (100 - 15 - 30)/100 = 55/100 = 0.55
0.55 ≠ 0.45
Incorrect

p(B or C) = (30 + 35)/100 = 65/100 = 0.65
0.65 ≠ 0.35
Incorrect
