A researcher is selecting lab rats for her experiment. She assigns each rat a number and picks numbers out of a hat while blindfolded. The pool of rats from which she is drawing participants is composed of the following: 23 male albino rats 21 male spotted rats 35 female albino rats 11 female spotted rats If she reaches into the hat twice, what is the probability of choosing a male albino rat and then either a female albino rat or a male spotted rat
Answers
Answer: [tex]\dfrac{76}{89}[/tex]
Step-by-step explanation:
The pool of rats from which the researcher is drawing participants is composed of the following:
23 male albino rats
21 male spotted rats
35 female albino rats
11 female spotted rats
Total rats = 23+21+35+11 =90
[tex]P(male\ albino)=\dfrac{23}{90}[/tex]
After drawing first rat , total rats remained = 89
[tex]P(\text{either a female albino rat or a male spotted rat})=\dfrac{35+21}{89}=\dfrac{76}{89}[/tex]
The probability of choosing a male albino rat and then either a female albino rat or a male spotted rat = [tex]\dfrac{76}{89}[/tex]

A container is in the shape of a right rectangular prism. Hayden wants to put a stick in the container.
What is the length in inches of the longest stick that will fit in the container
Answers
Answer:
13 in.
Step-by-step explanation:
First figure out the length of the diagonal of the base.
3²+4²=c²
9+16=c²
25=c²
√25=c
c=5
Now we can figure out the stick using the same method.
5²=12²=c²
25+144=c²
169=c²
√169=c
c=13
Lucas is having the Sunday blues and hoping for a snow day this week. He measures that there are currently 10
inches of snow on the ground.
The forecast for Monday is a 50% chance of 2.5 inches of snow. If it doesn't snow, 1.5 inches of snow will melt.
The forecast for Tueſday is a 50% chance of 1.5 inches of snow. If it doesn't snow, 0.5 inches of snow will melt.
The weather on Monday and Tuesday are independent events.
If X is a random variable that represents the amount of snow on the ground after Tuesday, drag the bars to
graph the probability distribution for all possible values of X.
Answers
Answer:
All probablities are 0.25
Step-by-step explanation:
Got it right on Khan
From the given question, we can see that there is currently ten inches of snow.
With this in mind, we can see that the weather forecast for Monday is 50% probability for 2.5 inches of snow which is 1/2 for 2.5 inches of snow.
Furthermore, if it does not snow, then there would be 2.5-1.5= 1.0 inches of snow
Additionally, the weather forecast for Tuesday is 50% probability for 1.5 inches of snow which is 1/2 for 2.5 inches of snow.
Furthermore, if it does not snow, then there would be 1.5-0.5= 1.0 inches of snow
Given that the weather on Monday and Tuesday are independent events, then all the probabilities would be 1/2:1 which would be 0.5 inches of snow.
With this in mind, all the probabilities for chances of snow is 0.25
Therefore, we can see that all the possible values of x would be 0.25

Rotate one of them so the right angle is in the same orientation as the other one.
1. AB = DE
2. CB = FE
3. AC = DF
4. Compare the length of two known sides: cb and EF
CB = 3 and EF = 8

5. Ab is side de. Multiply the length of ab by the scale factor:
4 x 2 2/3 = 10 2/3

Good luck
The division of the number 405 in the ratio 4:11 is 297 and 108 respectively.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the ratio is 4:11. the number is 405 which has to be divided by the ratio.
Let the common ratio between the numbers is x. Form an equation and solve for x.
4x + 11x = 405
15x = 405
x = 405 / 15
x = 27
The numbers are,
4x = ( 4 x 27 ) = 108
11x = ( 11 x 27 ) = 297
Therefore, the division of the number 405 in the ratio 4:11 is 297 and 108 respectively.

Which function is equivalent to g(x) = x2 + 15x – 54?
g(x) = (x + 9)(x – 6)
g(x) = (x – 9)(x + 6)
g(x) = (x – 18)(x + 3)
g(x) = (x + 18)(x – 3)
Answers
Answer:
g(x)=(x+18)+(x-3)
Step-by-step explanation:
The function i.e. g(x)=(x+18)(x-3) equivalent to the given equation.
Given that,
The equation is [tex]g(x) = x^2 + 15x - 54[/tex].We need to solve it.
Based on the above information, the calculation is as follows:

The demand d for a company’s product at cost x is predicted by the function d(x) = 500 – 2x. The price p in dollars that the company can charge for the product is given by p(x) = x + 5. Use the formula Revenue = price × demand to find the revenue function for the product.
R(x) = ________ + ________ x – _______ x^2
Answers
Answer:
-2x²+490x+2500
Step-by-step explanation:
Given that,
Demand, D(x) = 500-2x
The price for the product, P(x) = x+5
We need to find the revenue for the product. The formula for the revenue is given by :
Revenue = price × demand
Substitute all the values,
R = (x+5)(500-2x)
= 500x -2x² + 2500 -10x
= -2x²+490x+2500
So, the expression for the revenue function is "-2x²+490x+2500".
