Answer:
: P=0.60
: P>0.60
Step-by-step explanation:
Hypothesis test requires to state a null hypothesis and an alternative hypothesis. The hypotheses are stated in such a way that they are mutually exclusive. That is, if one is true, the other must be false; and vice versa. Then sample data will be used to accept or reject the null hypothesis in a given significance level.
Let P be the true proportion of customers that are carrying two Wi-Fi devices.
We can state the null and alternative hypothesis as follows:
: P=0.60
: P>0.60
Before conducting the test, we need to check if n×0.06≥10
Since n=78 this condition holds, therefore we can apply the hypothesis test.
Answer:
-14=8x
Step-by-step
-14=3x+5x
-14=8x
If you want the answer for the equation:
-14/8=x
-7/4=x
(3,-1) is the answer for mare
Obtuse because its larger than a right angle
isosceles because the two sides are equal
Answer:
Please check the attached diagram.
Thus, we conclude that:
In the diagram,
- The red line represents the parent function f(x) = x
- The blue line represents the function f(x) = x+1
The blue line indicates that the parent function has been shifted 1 unit upward.
Step-by-step explanation:
Let us recall some transformation knowledge.
We know that
if y = f(x), then y = f(x) + b simply means a transformation of (0, b).
In other words, if we add some constant let say 'b' in the output or y-value, the graph simply shifts upward by b units.
Given that
f(x) = x
so
f(x+1) = x+1 means the parent function f(x) = x has been shifted 1 unit upward.
Please check the attached diagram.
Thus, we conclude that:
In the diagram,
- The red line represents the parent function f(x) = x
- The blue line represents the function f(x) = x+1
The blue line indicates that the parent function has been shifted 1 unit upward.
