The sum of two numbers is twice their difference. the larger number is 9 more than twice the smaller. find the numbers.

melomori [17]

small number = x and large number = 2x + 9

x + 2x + 9 = 2(2x + 9 - x)

3x + 9 = 2x + 18

x= 9

2(9) + 9 = 27

Small number = 9 and large number = 27

The probability that Sandra gets a ride to work on any morning is 0.7. The probability that she gets a ride 3 times in a 5-day w

guajiro [1.7K]

Answer: The probability that she gets a ride 3 times in a 5-day work week is <u>0.31</u>.

The probability that she gets a ride at least 2 times in a 5-day workweek is <u>0.97</u>.

Step-by-step explanation:

By binomial distribution formula:

$P[X=r]=^nC_rp^rq^{n-r}$ , where n is the number of trials , r is the number of success, p is the probability of success and q is the probability of failure.

Given : n=5

p = 0.7

q= 1-0.7=0.3

Now, the probability that she gets a ride 3 times in a 5-day work week :

$P[X=3]=^5C_3(0.7)^3(0.3)^{5-3}\\\\=10(0.7)^3(0.3)^2=0.3087\approx0.31$

The probability that she gets a ride at least 2 times in a 5-day workweek :

$P[X\geq2]=1-P[X$
