As part of the underwriting process for insurance, each prospective policyholder is tested for high blood pressure. Let X repres
xxTIMURxx [149]

Answer:

0.053

Step-by-step explanation:

This is a geometric distribution problem.

I'm geometric distribution problem,

E(X) = 1/p

Where;

E(X) is expected value and p is probability of success

Thus;

1/p = 12.5

p = 1/12.5

p = 0.08

Now, to find the probability that the sixth person tested is the first one with high blood pressure, we will use the probability formula in geometric distribution which is;

P(X = k) = qⁿ•p

q = 1 - p

q = 1 - 0.08

q = 0.92

Thus;probability that the sixth person tested is the first one with high blood pressure will be expressed as;

P(X > 5) = (0.92^(5)) × 0.08

P(X > 5) = 0.053

*need to know in the next hour*
Genrish500 [490]

Answer:

20 blocks per pound

Step-by-step explanation:

We can see the line of best fit goes through the points (0, 0) and (5, 100).  WE will use these to find the slope:

m=\frac{y_2-y_1}{x_2-x_1}

Using our points,

m=\frac{100-0}{5-0}\\\\=\frac{100}{5}\\\\=20

This makes the slope 20 blocks per pound.

PLEASE HELP ME!! LAST ASSIGNMENT
Darya [45]

Answer:

u = 3

Step-by-step explanation:

\frac{10}{14} = \frac{35}{u + 46} \\\\ 10(u + 46) = 35×14 \\\ 10u + 460 = 490 \\\ 10u = 490 - 460 \\\ 10u = 30 \\\ u = \frac{30}{10} \\\\ u = 3

I hope I've helped you.
