Hello Gaby!
600....> 100%
240...> x%
Cross multiply
600 * x = 100 * 240
600x = 24 000
x = 24000/600
x = 40
Thus,
Sam saved 40% so far.
As always, it is my pleasure to help students like you!
Answer:
a)The P-value will be too small
b) He will reject the Null hypothesis
Step-by-step explanation:
a) If David incorrectly uses the z-distribution instead of the t-distribution, he will obtain a p-value that is too small because p-values obtained using Z distribution are smaller when compared to p-values obtained using t-distribution
b) He will reject the Null hypothesis given that the P value he will obtain will be very different from the one he obtained using z-distribution
Answer:
Step-by-step explanation:
Given
Coordinate: (-3,-9) and (4,5)
Ratio= 5 : 2
Required
Determine the point at the segment
The coordinate of the point is calculated using:
Where:
So, we have:
<em>The coordinate of the point is: (2,1)</em>
The height is given as 9 ft. this is also the radius of the circle.
The base of the triangle would be 2 times the radius = 18 feet.
The area of the triangle is 1/2 x 9 x 18 = 81 square feet.
The area of the semi circle is : 1/2 x PI x r^2 = 1/2 x 3.14 x 9^2 = 127.17
The area of the shaded region is the area of the triangle minus the area of the semi circle:
127.17 - 81 = 46.17 square feet.
