Based on the number of times Johnny performs the experiment, the order from the largest difference in relative frequency and actual prob. to the smallest is:
The difference between absolute probability and relative frequency will be larger if the number of experiments performed is smaller.
This is why the largest difference was seen when Johnny performed the experiment 20 times and the smallest difference was seen when the experiment was done 75 times.

The biologist is expecting the number of salmon to rise during salmon season. If the ratio stays the same and he expects 120 Steelhead, how many Chinook should he expect to count at the dam? Show your work.
Based on the ratio of Chinooks to Steelhead, if there are 120 Steelheads, the biologist should expect to count 48 Chinooks.
How many Chinooks will the Biologist find?The first part of the question shows that for every 4 Chinooks, there are 10 Steelheads.
The ratio of Chinooks to Salmon is therefore:
= 10 / 4
= 2.5
This means that for every 1 Chinook, there are 2.5 Steelhead.
If there are 120 Steelheads, the number of Chinooks would be:
= 120 / 2.5
= 48 Chinooks

An apartment complex is turning the grassy area next to the current parking lot into more parking space.Once they are done,how much total parking area will there be?
Once the apartment complex have been turned to a parking area, the total parking area will be 1620 square units
How to determine the total parking area?From the complete question, the parking area consists of the following shapes and dimensions
Rectangle: 28 units by 40 unitsRectangle: 20 units by 25 unitsThe area of a rectangle is the product of its dimensions.
So, the area of the parking area is:
Area = 28x40 + 20x25
Evaluate the products
Area = 1120 + 500
Evaluate the sum
Area = 1620
Hence, the total area of the parking area is 1620 square units

Maria tiene $900 pesos y Juan tiene el doble de la tercera parte de María.
Si la suma del dinero de Pedro y Juan es de $1000 pesos ¿cuánto dinero tiene Pedro?
Resolviendo un par de ecuaciones lineales veremos que pedro tiene 400 pesos.
¿Cuánto dinero tiene Pedro?Sabemos que:
María tiene 900 pesos.
Juan tiene el doble de la tercera parte de María, entonces:
J = (2/3)*$900 = $600
Juan tiene 600 pesos.
Finalmente, sabemos que la suma del dinero de Pedro y Juan es de $1,000 pesos, entonces tenemos que resolver la ecuación lineal:
P + J = $1,000
P + $600 = $1,000
P = $1,000 - $600 = $400
Pedro tiene 400 pesos.

Answer:
y=1/2x-6
Step-by-step explanation:
Slope intercept form is y=mx+b so plug it into the equation and it is y=1/2x-6.
y=1/2-6
Solution:Since we're given the line's slope and y-intercept, we can easily determine its equation.Remember, slope-intercept looks like so: y=mx+bIn this formula, the letter "m" stands for the slope, and "b" stands for the y-intercept.Therefore, the line's equation is:y=1/2-6Hope it helps.

Answer:
Answers : 945 males
Step-by-step explanation:
37%
555 females
1500 - 555
total males = 945
Answer:
945 males
Step-by-step explanation:
37% of 1500 = female
37% of 1500 = 555 (number of females)
1500 - 555 = number of males
1500-555 = 945
To double check this, we can do:
100% - 37% = 63% of 1500 are males
63% of 1500 = 945
So, the answer is 945
I can assure you this is the correct answer.

5 3.2 0.8
A solution to this equation to the nearest whole number is x = .
Does this equation have any other solutions?
The solution of the equation is approximately x = 4 and there are no other solutions
How to determine the solution of the equation?The equation is given as
0.1(2^x) = 4/x
Also, we have the table of values as one of the given parameters
Next, we check the table of values
From the table of values, we can see that:
The value of x is between x = 3 and x = 4
This is so because the values of the expressions 0.1(2^x) and 4/x are closest at these values
However, the value of x is closer to 4 than 3
This means that
x = 4 (approximately)
Hence, the solution of the equation is approximately x = 4 and there are no other solutions

For pattern Q we start at 6, and then we subtract 2 and multiply by 2 to get the next element.
[tex]b_1 = 6\\\\b_2 = (6 - 2)*2 = 8\\\\b_3 = (8 - 2)*2 = 12\\\\b_4 = (12 - 2)*2 = 20\\\\b_5 = (20 - 2)*2 = 36\\\\[/tex]
