Tan Ф= opposite side / adjacent side

Data:
adjacent side=15
Ф=30º

so:
tan 30º=x/15
x=15(tan 30º)
x=15(1/2)
x=7.5

Answer: x=7.5

A car insurance company has determined that 66​% of all drivers were involved in a car accident last year. Among the 1010 driver
jenyasd209 [6]

Answer: Our required probability is 0.618.

Step-by-step explanation:

Since we have given that

Probability of all drivers were involved in a car accident last year = 66%

Number of drivers = 10

Number of drivers involved in a car accident = 3

So, probability of drivers involved in car accident is given by

\dfrac{3}{10}\\\\=0.3

Probability of getting 3 or more who were involved in a car accident is given by

P(X≥3)=1-P(X=0)-P(X=1)-P(X=2)

Here,

P(X=0)=^{10}C_0(0.7)^{10}=0.028\\\\P(X=1)=^{10}C_1(0.7)^9(0.3)=0.121\\\\P(X=2)=^{10}C_2(0.7)^8(0.3)^2=0.233

So, our equation becomes

P(X≥3)=1-P(X=0)-P(X=1)-P(X=2)

P(X\geq 3)=1-0.028-0.121-0.233=0.618

Hence, our required probability is 0.618.

10-mg Atorvastatin Placebo Headache 15 65 No headache 17 3 3. If two different subjects are randomly selected, find the probabil
balu736 [363]

Answer:

0.6384

Step-by-step explanation:

Given that:

10-mg Atorvastatin Placebo Headache  15      65       No headache 17      3

Hence the total of number of patients = 15 + 65 + 17 + 3 = 100 patients

The number of patients with headache = 15 + 65 = 80 patients

Also, C(n, x) is the number of combinations in which n items can be chosen taken x at a time it is given by the formula:

C(n,x)=\frac{n!}{(n-x)!x!}

The the probability that if two different subjects they both had a headache = \frac{C(80,2)}{C(100,2)}=\frac{\frac{80!}{(80-2)!2!} }{\frac{100!}{(100-2)!2!} }  =\frac{3160}{4950}=0.6384
