Answer: Carson's average points in each game = 122

Jana's average points in each game = 104.4

Step-by-step explanation:

By the given table,

1) The total points Carson get in the game = 366,

He played games = 3,

⇒ His average point in each game = Total points he get/ total game he play

= 366/3

= 122

2) Now, The total points Jana get in the game = 522,

She played games = 5,

⇒ Her average point in each game = Total points she get/ total game she play

= 522/5

= 104.4

3.48 An apartment seeker in Manhattan estimates that 10% of the available apartments in her price range are in acceptable condit

REY [17]

Answer:

a) 10 weeks

b) P(k≤2)=0.190

c) P(k>17)=0.167

Step-by-step explanation:

This problem can be solved applying the geometric distribution.

The probability of needing k weeks to find an acceptable apartment can be written as:

$P(k)=(1-p)^{k-1}p=0.9^{k-1}\cdot 0.1$

a) The expected value of this distribution is:

$E(x)=1/p=1/0.1=10$

Answer: 10 weeks

b) The probability of finding an acceptable department in the first 2 weeks is:

$P(k\leq2)=P(1)+P(2)=0.1*0.9^0+0.1*0.9^1\\\\P(k\leq 2)=0.1+0.09=0.19$

c) We have to calculate P(k>17)

$P(k>17)=1-\sum_1^{17}P(k_i)\\\\P(k>17)=1-(P(1)+P(2)+P(3)+...+P(17))\\\\P(k>17)=1-(0.1+0.09+0.081+0.073+0.066+0.059+0.053+0.048+0.043+0.039+0.035+0.031+0.028+0.025+0.023+0.021+0.019)\\\\P(k>17)=1-0.833=0.167$

2x+y=7 however im looking for y <br> please help out with this T_T

natka813 [3]

Answer: y=-2x+7

Step-by-step explanation:

If all you are asking for is to solve for y, then that means you have to isolate this variable. You can do so by simply subtracting 2x from both sides of the equation. This leaves you with y=-2x+7. Hope this helps!
