Answer:
b 375
Step-by-step explanation:
The value of the standardized test statistic for this significance test is 1.7265
Standardized test statistic
In statistics, the standardized test statistic means a way for you to compare your results to a “normal” population.
Given,
A city ordinance requires that more than 75% of its residents must agree to the construction of new public buildings (using tax dollars) before any such structures can be built. a proposal has been made to build a new recreational facility in the city, and sponsors of the proposal want to conduct a small survey to see if it would be approved if put to an official vote of all residents. a simple random sample of 150 residents revealed that 123 supported a change (and 27 did not).
Here we need to find the value of the standardized test statistic for this significance test.
While we looking into the given question we have identified the following values,
Random samples = 150
Supported values = 123
Not supported = 23
Aggreged percentage = 75%
So, the null and alternative hypotheses were as follows: H0: p = 0.75 and Ha: p ≠ 0.75.
Then the value of Standardized test statistic is calculated as,
=> (150 - 123) / (75 / √23)
=> 1.7265

Example :
20 + 30.....GCF = 10
10(2 + 3)
The GCF of the number now is 1....because u have basically already factored the GCF out.....leaving only 1 as a factor now
here's another one...
3 + 9...GCF = 3
3(1 + 3)
so the GCF now is 1
Substitute the x for 5, so your equation would be 2(5)-4
Answer:
The general equation for a line (written in the slope-intersect form) is:
y = f(x) = a*x + b
Such that the line is already written in function notation.
Where a is the slope, and b is the y-intersect.
If a line passes through a point (x₁, y₁) and (x₂, y₂), the slope can be written as:
y = (y₂ - y₁)/(x₂ - x₁)
We know that the line in the graph passes through the points:
(-2, -1) and (2, 0)
Then the slope of the line will be:
a = (0 - (-1))/(2 - (-2)) = 1/4
Then the function for the line will be something like:
y = f(x) = (1/4)*x + b
Now we want to find the value of b.
Because we know that this function passes through the point (2, 0), this means that:
f(2) = 0 = (1/4)*2 + b
We can solve that for b:
0 = 2/4 + b
-2/4 = b
Then the function for the line is:
y = f(x) = (1/4)*x - 2/4
