Answer:
m(x)
Step-by-step explanation:
they would have to pass the horizontal line test and the vertical line test for both the origional and the inverse.
b(x) does not pass the horizontal line test in any of the y values over 3
d(x) does not pass the horizontal line test for y=-9
p(x) does not pass the horizontal line test for positive y values
and m(x) has only one corresponding x value for every y value
Answer: c. z = 1.35; Reject the null hypothesis
Step-by-step explanation:
Let 
be the average life expectancy of its batteries.
As per given , we have
Null hypothesis : 
Alternative hypothesis : 
Since 
is right-tailed and population standard deviation is also known, so we perform right-tailed z-test.
Test statistic : 
where, n= sample size
= sample mean
= Population mean
=population standard deviation
For 
, we have
Critical one-tailed test value for 0.10 significance level :
Decision : Since critical z value (1.28) < test statistic (1.35), so we reject the null hypothesis .
[When critical value is less than the test statistic value , we reject the null hypothesis .]
Answer: $5
Step-by-step explanation: 4 children divided by 20 equals 5
<h2>
Answer:</h2>
4x - 6 + 2x = 3(2x - 2)
4x - 6 + 2x = 6x - 6
[ both sides - 6 cancel each other ]
4x + 2x = 6x
6x = 6x
[ both sides 6x cancel each other ]
0 = 0.
