102+56= 158×2=316+338=654
she spent 654 on rent
71+7=78
y=x/4
78=x-y
plug in
78=x-x/4
78=4x/4-x/4
78=3x/4
312=3x
x=104
he got 104 from mowing the lawn
1/2 is the probability, or 50%. There are 4 teams of S and B n the Y, 2 are B. so its 2/4
<span>1.5 rev/s
Since angular momentum is conserved, the product of the moment of inertia and the rotational rate will remain a constant. So, assuming X as the desired rate of rotation we have:
X * 2.9 = 4.8 * 0.90
Now solve for X
X * 2.9 = 4.8 * 0.90
X * 2.9 = 4.32
X = 1.489655172
So when her arms and one leg go outward, her rotation slows to 1.489 rev/s. Rounding to 2 significant figures, gives 1.5 rev/s.</span>
Answer:
4.76% probability that a randomly selected person from the population has a positive test result
Step-by-step explanation:
We have these following probabilities:
4% probability of having the disease.
If a person has a disease, 95% probability of a positive test.
100-4 = 96% probability a person does not have the disease.
If a person does not have the disease, 1% probability of a positive test.
What is the probability that a randomly selected person from the population has a positive test result
95% of 4% and 1% of 96%. So
p = 0.95*0.04 + 0.01*0.96 = 0.0476
4.76% probability that a randomly selected person from the population has a positive test result
