Step-by-step explanation:
The "experimental probability" is the ratio of actual outcomes of interest to the number of trials. It is based on actually performing the selection over and over some number of times. The "theoretical probability" will be the fraction that is the outcomes of interest divided by the total number of possible outcomes.
We note that Mel's purse contains a total of 6 +8 +4 +7 = 25 coins. The theoretical probability of selecting any given coin is then 1/25.

A. The experimental probability of selecting a dime is ...
number of dime outcomes / number of trials = 30/150 = 1/5
B. The theoretical probability of selecting a dime is ...
(4 dimes)/(25 coins) = 4/25
C. The assumption in probability experiments is that randomly selected outcomes will always approach the theoretical probability in their frequency of occurrence.

A. The experimental probability of selecting a penny is ...
number of penny outcomes / number of trials = 45/200 = 9/40
B. The theoretical probability of selecting a penny is ...
(6 pennies)/(25 coins) = 6/25
C. The difference between these values is ...
6/25 -9/40 = 48/200 -45/200 = 3/200

Kenneth's bank account is modeled by the following equation f(x) = 13x+30
where x in the number of weeks and f(x) is total amount. How much money
was in Kenneth's account when it was opened?
Answers
When Kenneth opened her account, her account balance was 30.
A function is an expression that assigns each input value, say x, a unique output value, say y. Mathematically, a function can be represented as-
F(x) = x + a
Here, we are given that Kenneth's bank account is modeled by the following equation-
f(x) = 13x + 30
here, x = number of weeks
and f(x) = total amount
When Kenneth must've opened his account, the number of weeks would've been zero.
⇒ x = 0
Substituting the value of x = 0 in f(x), we get-
f(0) = 13(0) + 30
f(0) = 0 + 30
f(0) = 30
Thus, when Kenneth opened her account, her account balance was 30.

Using linear functions, the system of inequalities that matches the graph is given by:
y ≥ 3x.y > -2x - 1.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Given two points, the slope is given by change in y divided by change in x. For the first line, the points are:
(-1, -3) and (0,0).
Hence the slope is:
m = (0 - (-3))/(0 - (-1))
m = 3.
When x = 0, y = 0, hence the y-intercept is of b = 0 and the line is given by:
y = 3x.
Everything to the right of the solid line is shaded, hence the values that are equal(line is solid) or greater than the line compose the inequality, as follows:
y ≥ 3x.
For the second line, the points are:
(-2,3) and (1,-3).
Hence the slope is:
m = (-3 - 3)/(1 - (-2)) = -6/3 = -2.
Then:
y = -2x + b.
When x = -2, y = 3, hence:
3 = -2(-2) + b
b = -1.
Hence the line is:
y = -2x - 1.
Everything to the right of the dashed line is shaded, hence the inequality is:
y > -2x - 1.

Step-by-step explanation: ascending is rising so you would subtract feet, which in this case is 8 feet. after that you would consider that since she is underground the feet would be negative because she is below ground level which is zero. once you subtract it then you would get a grand total of -24 feet or 24 feet below the earth's surface but more than likely the answer would be -24 ft.

Answers
The decimal fraction is 0.28 and reduced fraction is 7/25.
What is fraction?In mathematics, the fraction is generally a term which define the small part of something or amount of something. A fraction has generally two parts a numerator and a denominator.
The general syntax for fraction is : [tex]\frac{x}{y}[/tex]
where, x is the numerator part
y is the denominator part
The fraction has two types of notations:
Decimal notation : In the decimal notation of fraction the term is written as the decimal form of x / y. we generally try to reduce the decimal value upto the nearest tenth.Reduce notation: In the reduce notation the structure of term is x/y but in this we try to convert the fraction into smallest fraction form.In the question given,
Total number of samples = 1214
Adults who answered peanut butter = 28%
Now, the decimal fraction = 28 / 100 = 0.28
and, the reduce fraction = 28/100 = (7)(4) / (25)(4) = 7/25
Hence, The decimal fraction is 0.28 and reduced fraction is 7/25.

Ruguru wants to rent a car for 3 days. The cost,C , in dollars, for the rental is shown in the box, where D is the number of days the car is rented If Ruguru has 115, how much more will he need to rent a car for 3 days?
Answers
Ruguru need $15 more to rent a car for 3 days.
Given,
Number of days Ruguru wants to rent a car = 3 days
The amount Ruguru has with him = $115
The cost for the rental of the car:
C = 25 + 35D
Where,
D is the number of days
Now,
Lets find the total rent of the car for 3 days
C = 25 + 35D
C = 25 + 35 × 3
C = 25 + 105
C = 130
The total rent of a car for 3 days is $130
We have to find the amount needed by Ruguru to rent a car for 3 days.
That is,
Total rent - Amount Ruguru has = Amount needed
130 - 115 = 15
Therefore,
Ruguru need $15 more to rent a car for 3 days.

15+3(2x-9)=44 solutions or no solution
Answers
when we take x = 9.33, the equation becomes true, which means that the linear equation has one solution.
Does the given linear equation has solutions?
Here we have the following linear equation:
15 + 3*(2x - 9) = 44
And we want to see if this has a solution, it means that there is a value of x such that the equation becomes true. Let's see that.
To do it, we need to isolate the variable, x, in one of the sides of the equation.
Expanding the product we get:
15 + 3*2x - 3*9 = 44
Moving the terms without x to the right side:
15 + 6x - 27 = 44
6x = 44 + 27 - 15 = 56
Now we can divide both sides by 6 so we get:
x = 56/6 = 9.33
So, when we take x = 9.33, the equation becomes true, which means that the linear equation has one solution.

What do you mean by possibility in mathematics?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. The probability of an occurrence is a number between 0 and 1, with 1 representing certainty and 0 representing impossibility. The higher the likelihood of an event, the more likely it is to occur. A straightforward illustration is tossing a fair (impartial) coin. Since there are no other conceivable outcomes and the coin is fair, the odds of both the possibilities, "heads" and "tails," are equally likely to occur. As a result, the probability of either occurrence is half.
