The state’s Gaming Control Board does random inspections of casino games. An inspector observed 40 spins of the roulette wheel i

n a certain casino, and she recorded whether the result was a red number ("r") or a black number ("b"). (Assume that none of these results was a "0" or "00," which are green numbers.) Her observations are given below (the first row has the first 20 observations, and the second row has the next 20 observations). At the 0.05 significance level, test the claim that the red and black numbers occur in a random order. b r r b b r b r b r b r r b r b b b b b r r r r r r b r r r b r b r r r b r b b Identify the value of the TEST STATISTIC used in the hypothesis test of this claim.

What is the equation of the linear function written in slope-intercept form?
-Dominant- [34]

Answer:

<h2>f(x) = -3x - 1</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

f(x)=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept, (0, b)</em>

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

From the graph we have two points <em>A(-1, 2)</em> and <em>B(0, -1) → b = -1</em>.

Calculate the slope:

m=\dfrac{-1-2}{0-(-1)}=\dfrac{-3}{1}=-3

Finally:

f(x)=-3x-1

Which graph best represents the function f(x)=2x ?
yan [13]

Answer:

B

Step-by-step explanation:

The best - well, only way- is to check a few points.

Namely -1 (unless your eyesight is really poor!), 0, 1, 2, and 3.

f(x) = 2^x\\f(-1) = 2^-^1 = \frac12\\f(0) =2^0 =1\\f(1)= 2^1=2\\f(2)=2^2=4\\f(3)=2^3= 8

Now you can mark all these points in each graph (well, you could if they were on paper and not on a screen) and see which one of the lines passes through all of them. Spoiler alert, it's the B graph.

A represents 2(2^x) = 2^{x+1}, B is the one you want, C is \frac{2^x}2 = 2^{x-1} and D looks like 4^x = 2^2^x

Anyone know the answer?
uysha [10]
AB = CB
Because they are congruent
Therefore CB = 5.9
Given perimeter = 17
CB+BE+ED+DC = 17
5.9 + BE + 2.8 + 5.6 = 17
BE + 14.3 = 17
BE = 17 - 14.3
= 2.7
