Answer:

a.) tanL= 0.533

b.) sinN= 0.882

c.) cosN= 0.471

Step-by-step explanation:

Triangle ABC is similar to Triangle LMN, which means that their corresponding angles are congruents.

Using SOH-CAH-TOA we have,

tanL~tanA= 8/15 = 0.533

sinN~sinC= 15/17 = 0.882

cosN~cosC= 8/17 = 0.471

Solve this equation. 5n+7=7(n+1)-2n
Trava [24]
5n + 7 = 7(n+1) - 2n

First distribute 7 to all terms inside the parenthesis

7(n) = 7n
7(1) = 7

5n + 7 = 7n - 2n + 7

Simplify. Combine like terms

5n + 7 = 5n + 7

True.

If you want to continue:

Isolate the n, move all variables to one side, and constants to the other

5n (-5n) + 7 (-7) = 5n (-5n) + 7 (-7)

0 = 0

True


hope this helps

SashulF [63]

Answer: 0.0473

Step-by-step explanation:

Given : The proportion of gambling addicts : p=0.30

Let x be the binomial variable that represents the number of persons are gambling addicts.

with parameter p=0.30 , n= 10

Using Binomial formula ,

P(x)=^nC_xp^x(1-p)^{n-x}

The required probability = P(x>5)=P(6)+P(7)+P(8)+P(9)+P(10)\\\\=^{10}C_6(0.3)^6(0.7)^{4}+^{10}C_7(0.3)^7(0.7)^{3}+^{10}C_8(0.3)^8(0.7)^{2}+^{10}C_9(0.3)^9(0.7)^{1}+^{10}C_{10}(0.3)^{10}(0.7)^{0}\\\\=\dfrac{10!}{4!6!}(0.3)^6(0.7)^{4}+\dfrac{10!}{3!7!}(0.3)^7(0.7)^{3}+\dfrac{10!}{2!8!}(0.3)^8(0.7)^{2}+\dfrac{10!}{9!1!}(0.3)^9(0.7)^{1}+(1)(0.3)^{10}\\\\=0.0473489874\approx0.0473

Hence, the required probability = 0.0473

Mrs. Chip bought 2 sheets and a blanket and paid $41. Mrs. Dale bought a sheet and 4 blankets and paid $80.
Katyanochek1 [597]

Answer:

  • Sheet = $12
  • Blanket = $17

Step-by-step explanation:

<u>Let the cost of a sheet be s and cost of a blanket be b</u>

  • 2s + b = 41
  • s + 4b = 80

<u>From the first equation we get:</u>

  • b = 41 - 2s

<u>Substitute in the second equation</u>

  • s + 4*(41 - 2s) = 80
  • s + 164 - 8s =  80
  • 7s = 84
  • s = 12

<u>Then</u>

  • b = 41- 2*12 = 17
