Answer:

0.9295 = 92.95% probability of getting someone who tests negative, given that he or she did not have the disease.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

11 + 145 = 156 people did not have the disease.

Out of those, 145 tested positive. So

p = \frac{145}{156} = 0.9295

0.9295 = 92.95% probability of getting someone who tests negative, given that he or she did not have the disease.

F(x) = 3 sin x + 3 cos x
Darina [25.2K]
F ( x ) = 3 sim x + 3 cos x
f ` ( x ) = 3 cos x - 3 sin x
f `` ( x ) = - 3 sin x - 3 cos x = - 3 ( sin x + cos x )
The inflection points:
- 3 ( sin x + cos x ) = 0
sin x + cos x = 0
sin x = - cos x / : cos x
tan x = - 1
x 1 = 3π / 4
x 2 = 7π / 4
The function is concave up when f``(x) > 0
- 3( sin x+ cos x ) > 0
sin x + cos x < 0
tan x < - 1
f is concave up for:
x ∈ ( π/2, 3π/4 ) ∪ ( 3π/2, 7π/4)
f is concave down for: 
x ∈ ( 0, π/2 ) ∪ ( 3π / 4, 3π/2 ) ∪ ( 7π / 4, 2 π ).

A truck hauls wheat to a storage granary. It carries a total of 4,970 bushels of wheat in 14 trips. How much does the truck haul
Alex17521 [72]

Answer:

355 bushels.

Step-by-step explanation:

To know the amount of wheat the truck hauls each trip, we need to divide the total amount of bushels of wheat  between the total of trips of the truck.

The total amount of bushels is 4970 and the total of trips is 14.

Then, the amount of bushels for each trip would be 4970/14 = 355.

Therefore, the truck hauls 355 bushels of wheat each trip.
