If a1= 3 and an= 2an-1 then find the value of 06.
I am Lyosha [343]

Answer:

a₆ = 96

Step-by-step explanation:

assuming you mean find a₆

using the recursive rule and a₁ = 3 , then

a₂ 2a₁ = 2 × 3 = 6

a₃ = 2a₂ = 2 × 6 = 12

a₄ = 2a₃ = 2 × 12 = 24

a₅ = 2a₄ = 2 × 24 = 48

a₆ = 2a₅ = 2 × 48 = 96

The ratio of the measures of the angles of a triangle is 7:5:8. What is the measure of the largest angle
kifflom [539]

Answer:

72° is the largest angle, 63°, 45°

Step-by-step explanation:

7x + 5x + 8x = 180

20x = 180

20x/20 = 180/20

x = 9

I set the equation equal to 180 because there are 180 degrees in a triangle.

Now find the largest angle, which will be the 8x, since 8 is bigger than 5 and 7.

8x

8(9)

72° is the largest angle

If you need the other two angle measures:

7x

7(9)

63°

5x

5(9)

45°

horsena [70]

Answer:

- the sample mean is 44

- the sample standard deviation is 12.35

Step-by-step explanation:

given information:

data, x_{i} = 36.45, 67.90, 38.77, 42.18, 26.72, 50.77, 39.0, 50.23

the number of data, n = 8

the sample mean, xbar

xbar = ∑x_{i}/n

       = (36.45+67.90+38.77+42.18+26.72+50.77+39.0+50.23)/8

       = 352.08/8

       = 44

standard deviation, s

s = \sqrt{sum(x_{i} - xbar)^{2}/n-1}

  = \sqrt{(36.45-44)^{2}+(36.45-44)^{2}.........(39.00-44)^{2}+(50.23-44)^{2}/(8-1 )}

 = \sqrt{\frac{1067.12}{7} }

 = 12.35
