Answer:
525,000 N
Step-by-step explanation:
Since Force is mass multiplied by acceleration, you have to create the equation 25000*21 m/s^2.
25000*21 = 525000
She hit the parked car with 525,000 Newtons of force.
Step-by-step explanation:
4 + x = -9
x = -9 +4
x = - 5
-x = -5
x = 5
Answer:
60°
Step-by-step explanation:
since angle on straight line is 180° you take the sum of the exterior angle of R and its interior angle then divide both sides by the coefficient of y to find y then things get easier from there
Answer:
0.1552
Step-by-step explanation:
Hi!
Give a random person, lets call:
D = the person has the disease
¬D = the person doesnt have the disease
T = the test on this person is positive (detects the disease)
¬T = the test on this person is negative
We are give the conditional probabilities:
P(T | D) = 0.9
P(¬T | ¬D) = 0.9
P(D) = 0.02
From those we know that:
P(T | ¬D) = 0.1
P(¬T | D) = 0.1
We must find P(D | T). For that we use Bayes theorem:
