STEP 1: WORK OUT RADIUS
Radius= (square root)(7-0)^2+(0-0)^2
=(sqrt)49
therfore radius=7
This means that the equation of the circle will be x+y=49
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

144 cm3 is what i came up with!
The additional true statement that would need to be given in order to state the conclusion using the law of detachment is 49,700 is divisible by 100.
<h3 /><h3>What is law of detachment?</h3>
Law of detachment states that if a facts is true and its hypothesis is true, then its conclusion is true.
For instance,
Statement A: If there's an increase in Mr Charles salary.
Statement B: Mr Charles buys bicycle for his son.
This means Mr Charles buying bicycle for his son is true because of the increase in income.
