Answer:

Step-by-step explanation:

14 bc you invert the triangle, 9× 2 is 18, so on the other side 6× 2 is 12, + 2 is 14

Answer:

X = 29

Step-by-step explanation:

Considering they are similar then the side A-B would have a ratio of 3:1 with J-K and since A-B = 6 and J-K = 18. Using this same logic B-C (X-2) = K-L (9). So BC = 9x3 which would mean X = (9x3 + 2) or 29

The probability distribution for the number of automobiles lined up at a Lakeside Olds dealer at opening time (7:30 a.m.) for se

Gala2k [10]

Answer:

$E(X) = \sum_{i=1}^n X_i P(X_i)$

And replacing we got:

$E(X) = 1*0.05 +2* 0.3 +3* 0.4 +4*0.25 = 2.85$

So we are going to expect about 2,85 automobiles for this case.

Step-by-step explanation:

For this case we define the random variable X as "number of automobiles lined up at a Lakeside Olds dealer at opening time (7:30 a.m.)" and we know the distribution for X is given by:

X 1 2 3 4

P(X) 0.05 0.30 0.40 0.25

The expected value of a random variable X is the n-th moment about zero of a probability density function f(x) if X is continuous, or the weighted average for a discrete probability distribution, if X is discrete

For this case we can calculate the epected value with this formula:

$E(X) = \sum_{i=1}^n X_i P(X_i)$

And replacing we got:

$E(X) = 1*0.05 +2* 0.3 +3* 0.4 +4*0.25 = 2.85$

So we are going to expect about 2,85 automobiles for this case.
