Answer:
The slope of line q is [tex]-\frac{7}{8}[/tex].
Step-by-step explanation:
We know that line p has a slope of [tex]-\frac{7}{8}[/tex], and that line p and line q are parallel. Parallel lines always have the same slope. Thus, the slope of line q must be [tex]-\frac{7}{8}[/tex] as well.
In a class of 22 students, 13 have a brother and 15 have a sister. There are 3 students who do not have any siblings. What is the probability that a student has a brother given that they do not have a sister?
Answer:
1/4
Step-by-step explanation:
The probability that a student has a brother given that they do not have a sister 9/7.
How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given;
[tex]\rm P(E)=\dfrac{Number \ of \ favourable \ events}{Number \ of \ total \ events}\\\\[/tex]
In a class of 22 students, 13 have a brother and 15 have a sister.
There are 3 students who do not have any siblings.
3 students don't have a sibling.
The probability that a student has a brother given that they do not have a sister is;
[tex]\rm P(E)=\dfrac{Number \ of \ favourable \ events}{Number \ of \ total \ events}\\\\ \rm P(E)=\dfrac{13+15-22+3}{22-15}\\\\\rm P(E)=\dfrac{31-22}{7}\\\\ P(E)=\dfrac{9}{7}[/tex]
So, the probability that a student has a brother given that they do not have a sister 9/7.

Answer:
First Blank: 1
Second Blank: -1 (x-3)
Third Blank: -1
Step-by-step explanation:
The expression [tex]\frac{x+3}{3+x}[/tex] is reduced to 1 and the expression [tex]\frac{3-x}{x-3}[/tex] is reduced to -1.
The two given expressions are [tex]\frac{x+3}{3+x}[/tex] and [tex]\frac{3-x}{x-3}[/tex].
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Here,
[tex]\frac{x+3}{3+x}=\frac{x+3}{x+3}=1[/tex]
Now, [tex]\frac{3-x}{x-3}=\frac{-(x-3)}{x-3}=-1[/tex]
Therefore, the expression [tex]\frac{x+3}{3+x}[/tex] is reduced to 1 and the expression [tex]\frac{3-x}{x-3}[/tex] is reduced to -1.

15.it will take 88 minutes to add 16 seats.
It will take 104.5 minutes to add 19 seats.
Step-by-step explanation:
Let m represent number of minutes.
We have been given that an assembly line worker at Rob's Bicycle factory adds a seat to a bicycle to a rate of 2 seats in 11 minutes.
We will use proportions to solve our given problem.
To find the time taken to add 16 seats, we will in our proportion as:
Therefore, it will take 88 minutes to add 16 seats.
To find the time taken to add 19 seats, we will in our proportion as:
Therefore, it will take 104.5 minutes to add 19 seats

Answer:
All equilateral triangles are acute angle triangles.
i need help telling if these are true or false
Answers:
FalseTrueFalseTrue======================================================
Explanations:
Point A is located at (0,1). It then moves to A' which is at (0,3). Note the y coordinate goes from y = 1 to y = 3, so the scale factor is 3/1 = 3 instead of 4. Therefore, the claim is false.Point A is at (-4,4). It moves to (-2,2). Each coordinate of (-4,4) is cut in half to get (-2,2). Cutting a value in half is the same as multiplying by 0.5, so point A fits the description. Let's find out if point B does as well. B is at (2,4) and it moves to B' (1,2); we can see that point B has its coordinates cut in half as well. Points C and D also work to fit the description (I'll let you check those coordinates) which means overall, quadrilateral ABCD dilates with a scale factor of 0.5 to get to quadrilateral A'B'C'D'. The answer here is "true".Point W is at the location (-1,1). Triple each coordinate to get (-3,3) which is where point W' should be located if we applied the dilation of scale factor 3. However, the diagram shows W' is not at (-3,3). It seems to be fairly close to (-2,2) if anything. We don't need to check the other points, but I recommend you do so just for practice. The answer here is "false".Because the scale factor is 0.25 = 1/4, this means "scale factor of 0.25" is the same as "scale factor of 1/4". That tells us to "multiply each coordinate by 1/4" which in turn is equivalent to "divide each coordinate by 4". Point E is at (-4,4) which moves to (-1,1) when we divide each coordinate by 4. Note how point E' is at (-1,1). So E moves in the proper way according to the instructions given to us. Points M, W and O also move in a similar fashion after we divide their coordinates by 4. The answer here is "true".A model car has a length of 7.25 inches. The actual car is 14.5 feet long. What is the scale of the model car?
Answer:
1:24
Step-by-step explanation:
Convert inches to feet, 7.25 inches is 0.604 feet.
0.604:14.5 needs to become 1:something, so set up 0.604/14.5 = 1/x
Solve for x now by dividing 14.5 by 0.604. You get 24 for x, so the answer is 1:24 scale!
