Three fourths of the offspring of two fruit flies have short wings, while the rest have wild-type wings . In a batch of offsprin

Umnica [9.8K]

Answer:

300

Step-by-step explanation:

If three-fourths of the offspring of two fruit flies have short wings and the rest have wild-type wings, then $1-\frac{3}{4}=\frac{1}{4}$ of the offspring must have wild-type wings. This means that the number of offspring that have short wings must be $\frac{3/4}{1/4}=\frac{3}{4}\cdot \frac{4}{1}=3$ times larger than the number of offspring that have wild-type wings. Since there are 100 offspring who have wild-type wings, there must be $100\cdot 3=\boxed{300}$ that have short wings.

<u>Alternative:</u>

If three-fourths of the offspring of two fruit flies have short wings and the rest have wild-type wings, then $1-\frac{3}{4}=\frac{1}{4}$ of the offspring must have wild-type wings. Therefore, 100 represents one-fourth of the total number of offspring, meaning there must be $100\cdot 4=400$ offspring total. Thus, there are $400-100=\boxed{300}$ offspring with short wings.

What is the midline equation of y = -4sin (2x - 7) + 3?

Georgia [21]

Answer:

$y = 3$ .

Step-by-step explanation:

The minimum and maximum value of $\sin(2\, x - 7)$ over all real $x$ are $(-1)$ and $1$ , respectively. Hence, the maximum and minimum value of $y = -4\, \sin(2\, x - 7) + 3$ would be:

Maximum: $y = (-4)\, (-1) + 3 = 7$ .
Minimum: $y = (-4)\, (1)\ + 3 = (-1)$ .

The midline equation of a sine wave is a horizontal line that is right in the middle of maximum and minimum $y$ -values of that sine wave. In the sine wave in this question, the average of the maximum and minimum $y\!$ -values is $(1/2) \, (7 + (-1)) = 3$ . Hence, the midline equation of this sine wave would be $y = 3$ .
