Answer:

g(-5) = -6

Step-by-step explanation:

We need to find value of g(-5)

Looking at the graph in figure when g = -5, the value on the graph is -6 as it is highlighted with blue point.

because we have x = -5 so, we will look at graph that passes through x and y when x= -5, so we get y=-6

So, g(-5) = -6

3.(8 points)Consider the following experiment:Experiment: A bag contains 3 red balls, 4 blue balls, 4 green balls and 3yellow ba

MakcuM [25]

Answer:

3 / 91

Step-by-step explanation:

Given :

Red balls = 3

Blue balls = 4

Green balls = 4

Yellow balls = 3

Total number of balls = (3+4+4+3) = 14

Sample space :

RR, BB, GG, YY, RB, BR, BG, GB, YG, GY, YR, RY, BY, YB, GR, RG

Probability of drawing two red balls without replacement :

1st draw :

P(red) = number of red balls / total number of balls

P(red) = 3/14

2nd draw :

P(red) = 2 / 13

Hence,

P(RR) = 3/14 * 2/13 = 6 / 182 = 3 / 91

lord [1]

Answer:

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 447 gram setting.

$H_0:\mu = 447\\H_a:\mu\neq 447$

Mean = $\mu = 447\\s = 21\\x = 443$

n = 19

Since n < 30 , so we will use t test

$t=\frac{x-\mu}{\frac{s}{\sqrt{n}}}$

Substitute the values :

$t=\frac{443-447}{\frac{21}{\sqrt{19}}}$

$t=−0.8302$

t calculated = -0.830

degree of freedom = n-1 = 19-1 = 18

A level of significance=α=0.025

$t_{(df,\frac{\alpha}{2})}=2.093$

t critical = 2.093

t calculated < t critical

So, We failed to reject null hypothesis

Decision rule -0.830< 2.093 So, We failed to reject null hypothesis

1. percent increase : (new number - original number) / (original number)...x 100

<span>(22 - 20) / 20 = 2/20 = 0.1.....0.1 x 100 = 10...so there is a 10% increase</span>
