Martha recorded the eye colors of the people who have already signed up for a lecture on genetics.
gray 1
brown 10
hazel 1
green 1
blue 7
Considering this data, how many of the next 16 people to sign up should you expect to be brown-eyed?
=====================================================
Explanation:
According to the table, 10 people have brown eyes. This is out of 1+10+1+1+7 = 20 people total. So 10/20 = 0.50 = 50% of the group has brown eyes.
If this trend holds up, then we expect 50% of the next group of 16 people also have brown eyes.
50% of 16 = 0.50*16 = 8
We expect 8 people to have brown eyes in this next group. This is of course assuming that the first group is unbiased and represents the population (or is close enough).

Find the measure of angle A:
Find the measure of angle B:
Answer:
Measure of angle A is 65 degrees and measure of angle B is 37 degrees.
Step-by-step explanation: First add all of the degrees of excluding x (4+(-9)) which is -5. Then subtract that from 180 since that is the sum of all the angles in a triangle which gives you 185. Then divide it by the number of "x's" that there are which is 5 which gives you 37. So angle B is x which is 37 degrees and angle a is 2(37)-9 which is 65 degrees. Hope this helps.

You roll a six sided number cube and flip a coin. What is the probability of rolling a number greater than 5 and flipping heads.
Answer:
1/6 for the number cube and 1/2 for coin
Step-by-step explanation:
Answer:
1/12
Step-by-step explanation:
There are a total of 12 possible outcomes (numbers 1 through 6, and a heads or tails for each one). There is only 1 outcome where the number rolled is greater than 5 (has to be 6) and you flip a head.
So there is a 1 out of 12 chance.

A regular hexagon has a perimeter of 127 m. Find its area to the nearest tenth.
Answer:
1164.01
Step-by-step explanation:
First you realize there is 6 sides on a hexagon. Then, you divide the 127 by 6. Then you split the hexagons into 6 parts. This leads you to a triangle. Then if you divide the degrees so 360 total degrees/6 parts = 60. If you split that triangle in half, the angle becomes 30 degrees. Then you will realize the 30 degree is pointed at the 127/12. Because you know the x, (x)(Square root 3), 2x theorem (the 30, 60, 90 triangle), you get the height of the triangle which is about 18.33 . Then you do the area of Triangle = 1/2 * base * height. Therefore you should get 194.00 Because there is 6 parts to a hexagon, you then need to multiply by 6. Your final answer should be 1164.01. This should be correct, please correct me if I’m wrong, thanks.

We can notice from the figure that : Area of the home plate is equal to sum of the Area of the rectangle ( 8 in x 15 in) and Area of the triangle with height 6 in and base 15 in.
Area of the rectangle : Length x Width
⇒ Area of the rectangle = 15 x 8 = 120 in²
Area of the triangle : 1/2 x Base x Height
⇒ Area of the triangle = 1/2 x 15 x 6 = 45 in²
Area of the home plate = Area of rectangle + Area of triangle
⇒ Area of the home plate = 120 in² + 45 in² = 165 in²

Q6) There are 40 boys and 20 girls at a party.
35% of the boys and 60% of the girls are wearing sunglasses.
How many people are wearing sunglasses altogether?
Answer: 26 people
Step-by-step explanation: For the boys, there are 40 boys and only 35% of them are wearing sunglasses. To find how many boys are wearing sunglasses, you have to find 35% of 40. 0.35 • 40 is 14. So 14 boys are wearing sunglasses. Now for the girls, there are 20 girls and 60% of them are wearing sunglasses. So, you find 60% of 20. 0.6 • 20 is 12. 12 girls are wearing sunglasses. However, since we want to know how many people are wearing sunglasses altogether, we need to add up the number of boys that are wearing sunglasses to the number of girls that are wearing sunglasses. 14 boys + 12 girls = 26.
So your final answer is: 26 people are wearing sunglasses altogether.

If you rotate a equilateral triangle by a side, what is the name of the resulting 3d shape
A solid of revolution is a three-dimensional figure obtained by rotating a two-dimensional figure (or curve) around a straight line (called the axis) that lies in the same plane. ... Since the triangle's interior is shaded, it creates the interior of the cone, creating a solid figure.
Three dimensional shapes are obtained by rotating the two dimensional shapes. When a circle is rotated we get sphere; when a triangle is rotated we get cone; when rectangle or square is rotated we get cylinder

Answer:
4608
Step-by-step explanation:
A tank contains 100 kg of salt and 1000 L of water. A solution of a concentration 0.05 kg of salt per liter enters a tank at the rate 99 L/min. The solution is mixed and drains from the tank at the same rate.
Required:
a. Find the amount of salt in the tank after 3.5 hours.
b. Find the concentration of salt in the solution in the tank as time approaches infinity.
Correct question is;
A tank contains 100 kg of salt and 1000 L of water. A solution of a concentration 0.05 kg of salt per liter enters a tank at the rate 9 L/min. The solution is mixed and drains from the tank at the same rate.
Required:
a. Find the amount of salt in the tank after 3.5 hours.
b. Find the concentration of salt in the solution in the tank as time approaches infinity.
Answer:
A) y(3.5) = 40.11 kg of salt
B) Concentration as time approaches infinity = 0.05 kg/l
Step-by-step explanation:
We are given;
Mass of salt; m_s = 50 kg
Volume of water; v_w = 1000 L
Rate at which salt enters = 0.05 kg/L × 9 L/min. = 0.45 kg/min
Since the solution drains at same rate as it enters, then;
Rate at which salt goes out = 9y/1000
Where y is the concentration in the tank.
Thus, the differential equation of the amount of water in the tank will be;
dy/dt = Rate at which salt enters - Rate at which salt goes out
dy/dt = 0.45 - (9y/1000)
Simplifying this gives;
dy/dt = (9/1000)(50 - y)
Rearranging, we have;
dy/(50 - y) = dt(9/1000)
Integrating both sides gives;
In(50 - y) = 9t/1000 + A
If we do exponents of both sides, we will get;
50 - y = Ae^(-9t/1000)
At initial conditions, y = 0 and t = 0.
Thus;
A = 50
Thus, quantity of salt in tank will be written as;
50 - y = 50e^(-9t/1000)
Making y the subject gives;
y = 50 - 50e^(-9t/1000)
At t = 3.5 hours = 210 minutes
y = 50 - 50e^(-9 × 180/1000)
y(3.5) = 40.11 kg of salt
As t approaches infinity, it means t will be zero. Thus;
y = 50 - 50e^(-9 × 0/1000)
y = 50 kg
Concentration = 50/1000 = 0.05 kg/l
