Answer: E: The number of books a person finished reading last month
Step-by-step explanation:
First, a discrete variable is a variable that only can take some given values in a set, the discrete variables are usually not dense, and a continuous variable is a variable that can take any value in a range (where the accepted values are dense).
So, for example, the set of the natural numbers is discrete, and the set of the real numbers can represent a continuous variable.
Here the only option that is really discrete will be the number of books that a person finished reading last month because here only positive whole numbers are accepted (you can not finish a 0.454 of a book)
The other options are continuous because all are classical measures.
For example, the weight of a person can jump between:
75.6kg and 75.7kg.
So you could think that this is discrete because the values between 75.6kg and 75.7g are not shown with our measuring device, but those will be added in the error of the measure because the weights between 75.6kg and 75.7kg are actually possible, so they must be accepted.
Option E is right.
A. The height of a person. Height is a continuous variable.
B . The weight of a person. Weight is a continuous variable.
C. The length of a person’s arm span. Length is a continuous variable.
D. The time it takes for a person to solve a puzzle. Time is a continuous variable.
E. The number of books a person finished reading last month. The number of books is discrete variable.

Answer:
Newtons 2nd law of motion
Step-by-step explanation:
Newton’s second law of motion is closely related to Newton’s first law of motion. It mathematically states the cause and effect relationship between force and changes in motion. Newton’s second law of motion is more quantitative and is used extensively to calculate what happens in situations involving a force. Before we can write down Newton’s second law as a simple equation giving the exact relationship of force, mass, and acceleration, we need to sharpen some ideas that have already been mentioned.

Noah solved an equation as shown below and found that the equation has infinitely many solutions. Negative 3 (x + 4) + 2 x = 2 (x minus 6) minus 3 x. Negative 3 x minus 12 + 2 x = 2 x minus 12 minus 3 x. Negative x minus 12 = negative x minus 12. Which explains whether Noah is correct? Noah is correct because the two sides of the equation are equivalent expressions. Noah is correct because if he continues the solution, the final solution will be x = negative 2. Noah is not correct because the equivalent expressions mean that there is no solution. Noah is not correct because he used the distributive property incorrectly.

Given two consecutive integers. The sum of four times the first integer and six times the second integer is 96. Find the integers.
Find the First Integer and Second Integer
Hey there! I'm happy to help!
If these are consecutive integers it means that they are one apart. Let's call our numbers x and y and create a system of equations. Our x will be the first integer and y will be the second.
y=x+1
4x+6y=96
We plug our y value into the second equation to solve for x.
4x+6(x+1)=96
We use the distributive property to undo the parentheses.
4x+6x+6=96
We combine like terms.
10x+6=96
We subtract 6 from both sides.
10x=90
And divide both sides by 10.
x=9
Since y is x+1, we know that y is 10.
Our integers are 9 and 10.

as the 3 in 43.92?
A. 235.16
C. 96.315
B. 394.8
D. 7.635
Answer:
Answer A : 235.16
Step-by-step explanation:
Notice that in the original number (43.92), the 3 is located in the column of the units. So we are looking for a number that contains a 3 in ten times as much, that is a number that contains a 3 in the column of the tenths.
From the four given choices, the only one with a 3 in the column of the tenths is the one in answer A: 235.16

3x-9-2x+4. answer????
which situation best represents the following equation 15+.15x<25+.05x
Answer:
x<10
Step-by-step explanation:
First, we want to move all of our like terms to one side. In the inequality, the variable x on one side and our whole numbers on the other.
To do this you have to cancel out 0.5x on the right side. So you need to subtract 0.5 from both sides.
This leaves you with 15+x<25. Subtract 15 from both sides which leaves you with x<10

The heart will beat 604800 times in 6 days.
Number of minutes in a day = 1440 minutes
Number of minutes in 6 days = 1440 × 6 = 8640 minutes
Since the heart beats 70 times per minute, the number of times that it'll beat in 6 days will be:
= 70 × 8640
= 604800
The heart will beat 604800 times in 6 days.

A student is taking a history course and an English course. He decides that the probability of passing the history course is .75 and the probability of passing the English course is .84. If these events are independent, what is the probability that (a) he passes both courses; (b) he passes exactly one of them
Answer:
a. 0.63
b. 0.33
Step-by-step explanation:
Here is a probability question. When two events are independent, it means that the probability of one of the events happening has no effect on the probability on the other happening.
From the question, let P(H) be the probability of passing the history course while P(E) is the probability of passing the English course;
By representation;
P(H) = 0.75
P(E) = 0.84
a) Probability of passing both
This means that he passes history and also passes English;
Mathematically that would be represented as;
P(E) * P(H) = 0.84 * 0.75 = 0.63
b) Probability that he passes exactly one of the courses.
This means that he passes one and he fails the other. Mathematically, we should remember that the probability of an event not happening = 1 - probability of the event happening
Let P’(H) and P’(E) be the probability of failing the history and english courses respectively;
Thus; P’(H) = 1 - 0.75 = 0.25
while P’(E) = 1-0.84 = 0.16
Now the probability that he passes exactly one means he passes one and fails the other.
So in this case, we have two scenarios; He passes History and fail English or passes English and fails history.
Thus, we have;
[P(H) and P’(E) or P(E) and P’(H)]
In probability, and means multiplication while or means addition; thus we have;
{P(H) * P’(E) } + {P’(H) * P(E)}
= ( 0.75 * 0.16) + (0.25 * 0.84)
= 0.12 + 0.21 = 0.33
true or false. Any 3 distinct points are always coplanar
Answer: False
Step-by-step explanation:
Three points are always coplanar, and if the points are distinct and non-collinear, the plane they determine is unique. However, a set of four or more distinct points will, in general, not lie in a single plane. Two lines in three-dimensional space are coplanar if there is a plane that includes them both.
Answer:
Coplanar means "lying on the same plane". Points are coplanar, if they are all on the same plane. Any three points are coplanar but with more than three points, there is the possibility that they are not coplanar so its false.
