Answer:
A rectangle.
Step-by-step explanation:
Since the cross-section will be perpendicular to the base, it is parallel to the lateral faces of the prism. This means it will be the same shape as the lateral faces.
The lateral faces of a rectangular prism are rectangles; this means this cross-section will be a rectangle as well.
Answer:
D
Step-by-step explanation:
We can use two proportion to solve this problem
2 : 5 = 10 : x
x = (5 * 10)/2 = 25 feet
2 : 5 = 6 : x
x = (6*5)/2 = 15 feet
10x^5 + 5x^3 - 14x^2 - 7
= 5x^3(2x^2 + 1) - 7(2x^2 + 1)
= (5x^3 - 7)(2x^2 + 1)
Answer is D
(5x^3 - 7)(2x^2 + 1)
Answer:
The probability that someone who tests positive actually has the disease is P(S|T)=0.43
Step-by-step explanation:
A pharmaceutical company has developed a test for a rare disease that is present in 0.5% of the population.
The test is 98% a positive result and the chance of a false positive is 7%
<h3>To find the probability that someone who tests positive actually has the disease:</h3>
Let S be the event that the rare disease present
P(S)=0.05 and
Let T be the event that the test is positive
P(T)=0.98
Then we have to find the Conditional probability :
By using the formula for Conditional Probability is
=0.4294
=0.43
<h3>
∴ P(S|T)=0.43</h3>
