The common fruit fly, Drosophila melanogaster, is the most studied organism in genetic research because it is small, easy to gro

w and reproduces rapidly. The length of the thorax (where the wings and legs attach) in a population of male fruit flies is approximately Normally distributed with mean 0.900 millimeters (mm) and standard deviation 0.068 mm.
(a) Choose a male fruit fly at random. What is the probability that the fly you choose has a thorax longer than 1mm? [2 marks]
(b) What proportion of male fruit flies have thorax length between 0.8mm and 0.95mm? [3 marks]
(c) What is the length of the thorax in a population of male fruit flies, if only 1% of male fruit flies have this length or longer? [3 marks]
(d) What are lengths of thorax encompass the middle 90% of the normal distribution?

An equilateral triangle has an apothem of 5 cm. Find the perimeter of the triangle to the nearest centimeter.
san4es73 [151]
The apothem is the distance from the center to the midpoint of one of the sides of a regular polygon.  You can make a right triangle with the apothem, the line from the midpoint to the corner and the line from the center to the corner.  An equilateral triangle has 60 degree angles (180/3).  The right triangle has half of one of those angles so 30 degrees.  Now we have a 30-60-90 triangle where the short leg is 5cm.  The long leg, which is also half of one side of the triangle is thus 5\sqrt{3}.  A whole side of the triangle is 10\sqrt{3}.  Multiply that by 3 to get the perimeter of <span>30\sqrt{3}.</span>

PLEASE HELP!! MATH FINAL
DaniilM [7]

Answer:

12 dimes, 8 nickels

Step-by-step explanation:

1. Set up an equation. Since we know the relationship between how many dimes and how many nickels that he has, we can create values for them.

2. Say that the number of nickels is x, so the number of dimes would be 2x-4.

3. Since we know that all of the coins that he has is 20 coins, we can say that 2x-4+x=20.

4. Solve the equation. We get 3x=24, and x=8.

5. That means that the number of nickels is 8, and the number of dimes is 2(8)-4, which is 12.

Answer: Timmy has 12 dimes and 8 nickels.
