Answer:

the probability that the obstetrician has delivered no child with polydactyly in her first 100 deliveries = 0.819

Step-by-step explanation:

This is a binomial distribution problem

Probability of a polydactyl case, p = 1/500 = 0.002

Probability of no polydactyl case, q = 1 - 0.002 = 0.998

Binomial distribution function is represented by

P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ

For this case,

x = 0

n = 100

P(X = 0) = ¹⁰⁰C₀ (0.02)⁰ (0.998)¹⁰⁰⁻⁰

P(X = 0) = ¹⁰⁰C₀ (0.02)⁰ (0.998)¹⁰⁰

P(X = 0) = 1 × 1 × 0.819 = 0.819

Alden paid to have some programs printed for the football game last weekend. The printing cost per program was 54 cents, and the
uranmaximum [27]

Answer:

300 programs

Step-by-step explanation:

Let’s work with cents to make this easier. We convert the $12 to cents, making 1200 cents

Let the number of copies Alden printed be x. His total printing cost would be x * 54 = 54x cents.

He sold at 75 cents each and still had left 100 copies. This means his total sale would be (x - 100)75

He lost $12 on the venture. This means his cost price minus his selling price is $12 since it’s a loss.

Computing this:

54x - 75(x - 100) = 1200

54x - 75x + 7500 = 1200

-21x = 1200 - 7500

-21x = -6,300

x = 6300/21 = 300 programs

20 POINTS BE HONEST AND TRY YOUR BEST
exis [7]
The trend of the plotted points has a positive slope, so we can eliminate -0.95 and 0. Next we need to determine how strong the correlation is from a scale of -1 to 1 where the strongest is closer to -1 or 1.

Since we cannot draw a line through all of the points, the answer cannot be 1.

Between 0.75 and 0.95, we should go with 0.95 because if we were to draw a best fit line through the points, most of them would be close to or on the line. If the answer was 0.75, the correlation would be much weaker.

So the answer is 0.95.
