Answer:
The P-value for this test is P=0.2415.
Step-by-step explanation:
We have to perform an hypothesis testing on the mean of alla account balances.
The claim is that the mean of all account balances is significantly greater than $1,150.
Then, the null and alternative hypothesis are:
The sample size is n=20, with a sample mean is 110 and standard deviation is 125.
We can calculate the t-statistic as:
The degrees of freedom fot this test are:
For this one-tailed test and 19 degrees of freedom, the P-value is:
Answer:
Step-by-step explanation:
From the diagram, quadrilateral BCEF is a cyclic quadrilateral.
Opposite angles if a cyclic quadrilateral sum up to 180°
The diagonals intersect at D to form two pairs of vertical angles, and vertical angles are congruent.
Also sum of angles in triangle CBD is 180°.
Answer:
m= -1/2
Explanation:
Use the <u>slope formula</u> to find the <u>slope</u> m
Seventy Thousand plus Four Hundred Thousand plus Ten Thousand plus Eight Thousand plus Five Hundred plus Thirty plus Nine.
Because otherwise the two circles you build wouldn't have any intersection!
You have to draw two circles, centered at the endpoints of the segment, and connect their intersection.
If the radii are less than half the length of the circle, the circles will have no interserction.
