Given sin
Effectus [21]

Answer: \frac{11}{12}

Step-by-step explanation:

<u>Use trigonometry (shown in image below) to find the 3 side-lengths:</u>

  • The side opposite of θ = \sqrt{23}
  • The base side adjacent to θ = 11
  • The hypotenuse = 12

<u>According to right triangle trigonometry:</u>

cos θ = \frac{adjacent}{hypotenuse}

<u>Substitute in the values:</u>

cos θ = \frac{11}{12}

Need rn. worth 30.
Likurg_2 [28]

Considering the situation described, the confidence interval is given by:

(0.35, 0.51).

<h3>What is a confidence interval?</h3>

It is given by the <u>estimate plus/minus the margin of error</u>.

For this problem, we have that:

  • The estimate is of 0.43.
  • The margin of error is half the range of the observations, hence M = (0.48 - 0.32)/2 = 0.08.

Then, the bounds of the interval are given by:

  • 0.43 - 0.08 = 0.35.
  • 0.43 + 0.08 = 0.51.

How many different 11-letter arrangements can be made using the letters in the word Firecracker?
zhenek [66]

Answer:

Total number of arrangements = 1,663,200

Step-by-step explanation:

Given:

11 - letter

FIRECRACKER

F = 1

I = 1

R = 3

E = 2

C = 2

A =1

K = 1

Find:

Total number of arrangements = ?

Computation:

Note: Repeated letter will be avoid.

Number\ of\  arrangements = \frac{!11}{!3 \times !2 \times !2}\\\\Number\ of\  arrangements = \frac{!11}{!3 \times !2 \times !2} \\\\Number\ of\  arrangements = \frac{11 \times 10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3}{3 \times 2 \times 2 } \\\\Number\ of\  arrangements = 1,663,200

Total number of arrangements = 1,663,200

Determine the nth term rule and find the 45th term for the arithmetic sequence with a10=1 and d=−6.
viktelen [127]

Answer:

The 45th term is equal to -209.

Step-by-step explanation:

I got stuck on this question for six attempts. Therefore I started trying other methods. I started with a10=1 and then subtracted 6 to get a11=-5. I continued this process until I reached a45=-209
