student to answer a question. Later, the
teacher randomly selects a different student
to answer another question. The first
student is a boy and the second student is a
girl.
Answer:
Independent events - Random selection of one
student - Selection of one boy to answer first question
Dependent Event - Selection of a girl student
Probability = 13.33 %
Step-by-step explanation:

What quantity of bananas would one dollar buy?
What is an equation of the line that passes through the points (-2,-6) and (6,8)?
Answer:
y=7/4x–5/2
Step-by-step explanation:
You must find the slope first, let it be m
[tex]m = \frac{y2 - y1}{x2 - x1} \\ = \frac{8 - ( - 6)}{6 - ( - 2)} \\ = \frac{14}{8} \\ = \frac{7}{4} [/tex]
then insert tu the formula y=mx+c to find the c (c is the intercept of y axis) choose any point that you want. i use (6,8)
[tex]y = mx + c \\ 8 = \frac{7}{4} (6) + c \\ c = - \frac{5}{2} [/tex]
so the equation is
[tex]y = \frac{7}{4} x - \frac{5}{2} [/tex]
7x – 8y = 112 in slope intercept form
Answer:
y = 7/8x-14
Step-by-step explanation:
I found the answer to this on a website.
Answer:
[tex]\bf\implies \boxed{\bf y = \dfrac{7}{8}x - 14} [/tex]
Step-by-step explanation:
We need convert the given equation into slope intercept form . The slope intercept form is ,
[tex]\bf\implies y = mx + c [/tex]
• So that ,
[tex]\bf\implies 7x - 8y = 112 [/tex]
[tex]\bf\implies -8y = 112 - 7x [/tex]
[tex]\bf\implies y =\dfrac{112-7x}{-8}[/tex]
[tex]\bf\implies y =\dfrac{112}{-8}-\dfrac{7x}{-8}[/tex]
[tex]\bf\implies \boxed{\bf y = \dfrac{7}{8}x - 14} [/tex]

What is the difference between the definitions for ray and line segment?
Only the definition of ray relies on an understanding of two directions.
Only the definition of line segment relies on an understanding of line.
Only the definition of ray depends on an understanding of infinite.
Only the definition of line segment depends on an understanding of point.
Answer:
Only the definition of the line segment depends on an understanding of point.

Find the circumference of a circle with a diameter of 400 cm. Use 3.14 for π.
A.
628 cm
B.
3.14 cm
C.
2512 cm
D.
1256 cm
Answer:
D. 1256 cm
Step-by-step explanation:
Divide the diameter by 2 to get the radius so 400/2 = 200
C = 2 π r = 2 · π · 200 = 1256.637
21 is less than or equal to -3(x-4) is less than 18
Answer:
-3 ≤ x <-2
Step-by-step explanation:
First, you should set up the equation to solve it, which is,
21 ≤ -3(x-4)<18
Then you should simplify the equation to,
21 ≤ -3x+12<18
Then subtract 12 from both sides.
9 ≤ -3x<6
Lastly, divide -3 from both sides.
-3 ≤ x<-2

Answer:
[tex]y = - \frac{7}{3} x + 4[/tex]
Step-by-step explanation:
I'm going to use the process of elimination to get rid of the equations. The equation for slope is y=mx+b with b being the y-intercept. As you can see the y-intercept in this graph is 4 which removes the third equation as a possible answer. The slope is moving from left to right in a downwards direction which means it is a negative slope. The only answer with a negative slope is b therfore it is your answer.
In 1992, the average electric bill for a single

Average rate = 690/28 = 24.64
What is a Translation?
Answer:
The displacement of a figure or a shape from one place to another is called translation, which means a figure can be moved upward, downward, left, right, or anywhere in the coordinate system using translation. While translating, all the points will shift by the same number of units.

What is the distance between points (8,3) and (3, 1) on the coordinate plane?
OA. 3 units
OB. 21 units
OC.29 units
OD. 7 units
Answer:
√29
Step-by-step explanation:
You would use the distance formula in this case to solve the problem:
(8-3)^2+(1-3)^2=29
Now square root 29, leaving you with √29.
Answer:
5.39
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√(3 - 8)² + (1 - 3)²
√(-5)² + (-2)²
√25 + 4
√29
= 5.39
