Answer:

572.4 m

Step-by-step explanation:

Fórmula del ángulo de elevación =

tan θ = Opuesto / Adyacente

θ = 3 °

Opuesto = 30 m

Adyacente =?

Por eso

bronceado 3 = 30 m / x

Multiplicar cruzada

bronceado 3 × x = 30 m

x = 30 m / bronceado 3

x = 572.43410063m

Aproximadamente = 572.4 m

Voting age
Levart [38]

Answer:

\frac{17}{64}\approx 0.27

Step-by-step explanation:

We have been given a table to voters and their ages. We are asked to find the probability that a voter is younger than 45.

Voting age         Voters

17-29                       9

30-44                      8

45-64                    32

65+                        15

We can see from our given table that age of 17 (9+8) voters is between 17 to 44 years.

To find the probability that a voter is younger than 45, we will divide 17 by total number of voters.

\text{Total voters}=9+8+32+15=64

\text{Probability that a voter is younger than 45}=\frac{17}{64}

\text{Probability that a voter is younger than 45}=0.265625

\text{Probability that a voter is younger than 45}\approx 0.27

Therefore, the probability that a voter is younger than 45 is 0.27.

What is the common ratio for this geometric sequence ? 16,8,4,2
ahrayia [7]

Hello from MrBillDoesMath!

Answer:   1/2

Discussion:

Note that:

16 /2 = 8  (the next term in the sequence)

8 /2 = 4  (the next term in the sequence)

4 /2 = 2  (the next term in the sequence)

We are repeatedly multiplying by 1/2



Thank you,

MrB
