Answer:
yes, we can reject the hypothesis
Step-by-step explanation:
The null hypothesis
H0 = mean weekly food budget for all households in this community is $98
Let´s find z
z= (x – mean) / standard deviation / √sample size
z = (100 – 98) / 10 / √100
z = 2
Using a Z table we can find probability
P (z>2) = 0.0228
Since P < α , results are significant and we can reject the hypothesis
Given:
A quadrilateral inscribed in a circle.
To find:
The values of a and b.
Solution:
A quadrilateral inscribed in a circle. So, the quadrilateral is a cyclic quadrilateral.
We know that the sum of the opposite angles of a cyclic quadrilateral is 180 degrees.



We know that the measure of arc is twice of measure of subtended angle on that arc.




Therefore, the value of a is 101 degrees and the value of b is 82 degrees.
