Answer:

The theoretical probability of obtaining letter 'r' at the 14th spin is:

1/8

Step-by-step explanation:

It is given that:

A spinner has 8 equal sectors with different letters for each sector.

The sectors are labeled b, y, g, p, o, v, m, and r.

Hamlet spins the spinner 13 times, and it stops at the letter r 9 times.

We are asked to find the theoretical probability that we will get  letter r at the 14th spin.

The theoretical Probability is given as the ratio of number of favorable outcomes to the total number of outcomes.

Hence, the theoretical probability of obtaining letter 'r' at the 14th spin is:

( As there are a total of 8 outcomes( or 8 sectors) out of which there is only one sector which is red)

Hope this helped

Is the given function exponential function?<br> 3x2 - 4x + 7 = 0 Yes or No? How do you know?
yawa3891 [41]

Answer: no

Step-by-step explanation:

because you can do what is known as the vertical line test to determine if it is a function you do that by plotting it and if it goes in a vertical line then it is a function

The sum of the first 3 terms of a geometric series is 171 and the common ratio is 2/3
S_A_V [24]

Answer:

81

Step-by-step explanation:

The formula for calculating the sum of geometric series varies depending on the value of its common ratio.

Given the common ratio to be 2/3 which is less than 1, the formula to be used is given as;

Sn = a(1-rⁿ)/1-r

n is the number of terms of the series

a is the first term

r is the common ratio.

Sn is the sum of the series

Given n = 3, r = 2/3 and Sn = 171,

a= ?

Substituting this values in the formula we have;

171 = a{1-(2/3)³}/1-2/3

171 = a{1-8/27}/(1/3)

171 = a(19/27)/(1/3)

171 = 19a/27 × 3/1

171 = 57a/27

57a = 171×27

57a = 4,617

a = 4,617/57

a = 81

The first term of the series is 81

What is the slope of the line passing through (16, -2) and (-30, 6)?
Novay_Z [31]

m=\frac{\Delta y}{\Delta x}=\frac{-2-6}{16-(-30)}=\frac{-8}{46}=\boxed{-\frac{4}{23}}.

Hope this helps.

How do I solve this? Like what are the steps to solving this question
ozzi

Answer:

1 = 35

2 = 55

Step-by-step explanation:

so we know that between 1 and 2 it is 90 degrees we also know that angle 1 and the angel to the left of it make 180 degrees so do

180 - 90 = 90

this means the angle next to line 1 is also 90 degrees

then we would see that the 55 degrees the 90 degrees and angle 1 make 180 degrees so do

55 + 90 = 145

180 - 145 = 35 degrees so angle 1 is 35 degrees

then we would find angle 2

90 - 35 = 55 degrees so angle 2 = 55

hope this helps : )
