Let the yellow corn be x

And other variety be y

Question says that she brought a dozen (as total)

So,

x +y = 12

If cost of yellow corn was 40 cent and cost of other varieties were 50 cents then,

(After changing those cents into dollar)

0.40x+ 0.50y = 5.70

Because she paid a total of 5 dollar 70 cents for yellow and other variety.

So, option "a" is correct.

Compare and contrast a square and parallelogram using a Venn diagram

Eva8 [605]

A square and a parallelogram both have 2 sets of parallel lines. A square has equal lengths for all four sides while a parallelogram doesn't. A parallelogram is a more broad idea because a parallelogram involves trapezoids, rectangles, and squares too.But a square is more specific.

Based on a survey, assume that 43% of consumers are comfortable having drones deliver their purchases. Suppose we want to find

svlad2 [7]

Answer:

The probability of getting two consumers comfortable with drones is 0.3424.

Step-by-step explanation:

The probability that a consumer is comfortable having drones deliver their purchases is, p = 0.43.

A random sample of n = 5 consumers are selected, and exactly x = 2 of them are comfortable with the drones.

To compute the probability of getting two consumers comfortable with drones followed by three consumers not comfortable, we will use the Binomial distribution instead of the multiplication rule to find the probability.

This is because in this case we need to compute the number of possible combinations of two consumers who are comfortable with drones.

So, X = number of consumers comfortable with drones, follows a Binomial distribution with parameters n = 5 and p = 0.43.

Compute the probability of getting two consumers comfortable with drones as follows:

$P(X=x)={5\choose x}\ 0.43^{x}\ (1-0.43)^{5-x};\ x=0,1,2,3...$

$P(X=2)={5\choose 2}\ 0.43^{2}\ (1-0.43)^{5-2}$

$=10\times 0.1849\times 0.185193\\=0.342421857\\\approx 0.3424$

Thus, the probability of getting two consumers comfortable with drones is 0.3424.

An angle whose measure is 405° is in standard position. In what quadrant does the terminal side of the angle fall?

ohaa [14]

Quadrant I

405=360+45 405-360=45

405 is one complete counterclockwise rotation plus one half of an angle measuring 90 degrees counterclockwise rotation (=45)
