Answer:

(1 - 2sinα)(1 + 2sinα)

Step-by-step explanation:

1 - 4sin²α ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

1 - 4sin²α

= 1² - (2sinα )²

= (1 - 2sinα)(1 + 2sinα)

Ede4ka [16]

Answer:

(a)1 out of 4.

(b)27%

(c)0.73 or 73%

Step-by-step explanation:

Tommy’s probability of winning is given as 0.27.

(a)Ratio Form

$0.27=\frac{27}{100} =27:100\\$Divide both sides of 27:100 by 27\\This gives:\approx 1:4$

Therefore, the probability that Tommy will win is <u>1 out of 4.</u>

(b)Exact Percent Value

Multiply the probability by 100 to obtain the exact percent value.

0.27 X 100=27%

(c)Probability that Tommy will not win.

Probability that Tommy will win+Probability that Tommy will not win=1

0.27+Probability that Tommy will not win=1

Probability that Tommy will not win=1-0.27

Probability that Tommy will not win=0.73

1) Find x, if 1/3 of x is 14

BartSMP [9]

"of" means multiply and "is" means equal

1. $\frac{1}{3}$ x = 14

x = 14(3) <em>multiply both sides by 3 to isolate "x"</em>

x = 42

2. $\frac{1}{5}$ x = 14

x = 14(5) <em>multiply both sides by 5 to isolate "x"</em>

x = 70

3. $\frac{2}{5}$ x = 14

2x = 14(5) <em>multiply both sides by 5 </em>

2x = 70

x = 35 <em>divide both sides by 2 to isolate "x"</em>

4. $\frac{7}{8}$ x = 14

7x = 14(8) <em>multiply both sides by 8 </em>

7x = 112

x = 16 <em>divide both sides by 7 to isolate "x"</em>

Answers: 42, 70, 35, 16
