Roll a pair of dice 10 times and count the number of times the sum is 6.
A. Binomial B. Geometric C. Cannot Determine
Binomial is the correct Answer. Roll a pair of dice 10 times and count the number of times the sum is 6 is a Binomial distribution.
Random variables of this type have several characteristics, but the key one is that the experiment that is being performed has only two possible outcomes - success or failure, which is called Binomial distribution.
A binomial experiment that satisfies these four conditions:
A fixed number of trialsEach trial is independent of the othersThere are only two outcomesThe probability of each outcome remains constant from trial to trial.A fair six-sided die is rolled ten times, and the number of 6's is recorded
There is a fixed number of trials ten rolls, each roll is independent of the others, and there are only two outcomes either it's a 6 or it isn't, and the probability of rolling a 6 is constant.

The term "rate of change" (ROC) describes the rate at which something changes over time. Thus, it is not the amount of individual changes themselves but rather the acceleration or deceleration of changes.
How do you find the average rate of change?When something changes over time, it does so at a certain rate, or ROC. Therefore, rather than the size of each change individually, it is the rate of change—or, more specifically, its acceleration or deceleration. Rate of change is a concept in finance that is used to comprehend price returns and pinpoint trends' momentum.
A ratio is used to express the rate of change, which contrasts the values of the y and x variables. The slope of the line represents the rate of change if it is linear, constant, and so on. Positive, negative, zero, or undefinable slopes are all possible for lines.

The general equation for depreciation is given by y = A(1 – r)t, where y = current value,
A = original cost, r = rate of depreciation, and t = time, in years.
The original value of a car is $24,000. It depreciates 15% annually. What is its value in 4 years?
Using the general equation for depreciation which is y = A(1 – r)^t, The value of the car in 4 years is $12528.15
How to find the value of the car in 4 yearsThe value of the car is solved by using the formula for depreciation which is y = A(1 – r)t
definition of variables
where
y = current value, = ?
A = original cost, = $24,000
r = rate of depreciation, = 15% and
t = time, in years. = 4 years
substituting the variables
current value, y = A(1 – r)t
current value, y = 24000 * (1 - 0.15)⁴
current value, y = 12528.15

Find m∠ABD and m∠DBC
Answer:
m∠ABD=116°
m∠DBC=64°
Step-by-step explanation:
The sum of the two angles given equals 180°. To find the two angle measures, use the following equation:
m∠ABD+m∠DBC=180°
For this problem, m∠ABD=(7x+67)° and m∠DBC=(8x+8)°. So,
(7x+67)°+(8x+8)°=180°
15x+75=180
15x=105
x=7
Next, substitute x=7 into the original expressions for the angle measures.
m∠ABD=(7(7)+67)°
m∠ABD=(49+67)°
m∠ABD=116°
and
m∠DBC=(8(7)+8)°
m∠DBC=(56+8)°
m∠DBC=64°

expand the bracket
x - 9 + 2x - 18 + x = 75
collect like terms
x +2x + x = 75 +27
add or subtract the like terms

In other words, a word problem is a verbal description of a problem situation wherein one or more questions are posed, the answers to which can be obtained by the application of mathematical operations to information available in the text.
Represent the three numbers with x, y, z
x = z-9
y = 2z
x+y+z = 75
substitute 2z for y in x+y+z
2z+x+z = 75
substitute z-9 for x
2z+z-9 = 75
3z- 9 = 75
3z = 75+9
3z = 84
z = 28
y = 2z
y = 2× 28
y = 56
to find the value of x;
x = 28-9

Two random number generators each generate a number from 1 to 10. What is the probability that both number generators generated the number 5? (Give your answer as a percentage, decimal or fraction in simplest form.)
The probability that both numbers generated the number '5' is 1/100
What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.
The probability is expressed as : sample space/ total outcome
Two number generators can generate number from 1 to 10. This means that the total outcome is 10.
The number 5 has a sample space of 1 in the generated numbers.
Therefore the probability to generate 5 in the first machine = 1/10
The probability to generate 5 in the second machine = 1/10
The probability to generate 5 in both machines = 1/10 × 1/10 = 1/100.

The slope of the line is -5/6 in the graph.
What is slope?The slope of a line is how steep it is going from LEFT to RIGHT. Slope is the proportion of a line's rise, or vertical change, to its run, or horizontal change.
No matter which two points you choose for the line's starting and ending points, the slope is always constant (it never changes).
From the given picture we can verify that
x₁ and y₁ is (-4, 6) and x₂ and y₂ is (2, 1).
We know the slope formula is y₂ - y₁ = m(x₂ - x₁)
Substituting the given details in formula we get
1 - 6 = m(2 - (-4))
-5 = m(6)
m = -5/6
Thus, the slope of the line is -5/6.

Let x be the number of games Don can bowl.
We can write the equation as:
25 - 5 - 2.5x = 0
This equation represents the total amount of money Don has, minus the cost of renting shoes, minus the cost of each game he bowls, which should equal zero if he wants to spend all of his money.

The probability of the first number being divided by the second number is greater than zero is 1/2.
What is probability?Probability is a way to gauge how likely something is to happen. According to the probability formula, the likelihood that an event will occur is equal to the proportion of positive outcomes to all outcomes. Probability that an event will occur P(E) is equal to the ratio of favourable outcomes to total outcomes. Because the favourable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1. Additionally, the proportion of positive outcomes cannot be negative.
Given four tiles in a bag with numbers -2, -1, 1, 2
one tile selected at random the probability is 1/4

the probability of the second tile is 1/4
total outcome for both is 4 x 4 = 16
