Step-by-step explanation:
Let E be the event of drawing a disc from the box of discs numbered from 1 to 90
Two digit numbers from 1 to 90=10,11,12,.....,90
No. of favorable outcomes=81
Total no. of possible outcomes =90
We know that, Probability P(E) =(Total no.of possible outcomes)(No.of favorable outcomes)=9081=109
Therefore, the probability of a two digit numbered disc from the box of discs numbered from 1 to 90=109

Use the Distributive Property to rewrite each expression. -3(-2x + 4)
-6x + 12
6x + 4
5x - 12
6x - 12
HELP ASAP
Answer:
hope this helps :)
Step-by-step explanation:
Find 62÷2. Use the distributive property.
Answer: The distributive property tells us how to solve expressions in the form of a(b + c). The distributive property is sometimes called the distributive law of multiplication and division. ... Then we need to remember to multiply first, before doing the addition!
Step-by-step explanation: According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Answer: 31
First, we can break down the number 62.
We will break the number 62 down into 60 + 2.
Now, we will divide the numbers we get after we break down 60.
60 ÷ 2 = 30
2 ÷ 2 = 1
30 + 1 = 31
The answer to your question is 31.

Which point lies on the circle x^2+y^2=100
A (0,-100)
B (10,-10)
C (25,75)
Answer:
NOT a single ordered pair satisfies the equation.
Step-by-step explanation:
Given the equation
[tex]x^2+y^2=100[/tex]
Let us substitute all the given ordered pairs to find which ordered pair satisfies the equation.
For (0, -100)
[tex]x^2+y^2=100[/tex]
substitute x=0 and y=-100
[tex]0^2+\left(-100\right)^2=100[/tex]
[tex]10000=100[/tex]
FALSE
Thus, the ordered pair (0, -100) does NOT satisfy the equation.
For (10, -10)
[tex]x^2+y^2=100[/tex]
substitute x=10 and y=-10
[tex]10^2+\left(-10\right)^2=100[/tex]
[tex]200=100[/tex]
FALSE
Thus, the ordered pair (10, -10) does NOT satisfy the equation.
For (25, 75)
[tex]x^2+y^2=100[/tex]
substitute x=25 and y=75
[tex]25^2+\left(75\right)^2=100[/tex]
[tex]6250=100[/tex]
FALSE
Thus, the ordered pair (25, 75) does NOT satisfy the equation.
Therefore, NOT a single ordered pair satisfies the equation.
In your own words, explain the steps you would need to take to find slope from data in a table.
When I say "your own words" PLEASE DON'T GIVE ME THE SAMPLE RESPONSE ON EDGE
Answer:
For me when I am finding the slope I actually use the slope formula [tex]\frac{y2-y1}{x2-x1}[/tex].
Step-by-step explanation:
Step 1 you have to find the x and y
Step 2: Use the slope formula
Step 3: Subtract y2 and y1 to get your answer
Step 4: Subtract x2 and x1 to get your answer
Step 4: If your answer is easy to divide simplify it, if not leave it as it is
That's all I know
I hope this helps :)
Answer:
Choose two sets of data (x and y values). Calculate the difference between the two y values. Calculate the difference between the corresponding two x values. Slope is the difference in y values / difference in x values.
Hope this Helps!
The graph represents f(x) = x + 3
On a coordinate plane, a step graph has horizontal segments that are each 1 unit long. The left end of each segment is an open circle. The right end of each segment is a closed circle. The left-most segment goes from (negative 5, negative 1) to (negative 4, negative 1). Each segment is 1 unit higher and 1 unit farther to the right than the previous segment. The right-most segment goes from (1, 5) to (2, 5).

What is the length of NM?
Answer:
See below :)
Step-by-step explanation:
We know that these traingles are all similar. We can see the angle NMK is 60 degrees so we also know that JNK is 60 degrees. Now we know that all of the triangles are 30-60-90 triangles. JN is 3, so from the "leg opposite to 30 degree theorem", we know that NK is two times JN which is 6. Then from the same theorem, we know that NM is NK divided by the square root of 3
[tex]\frac{6}{\sqrt3}[/tex]
We can't have fractions that have irrational numbers in the denominator of a fraction so we multiply it by root3 over root3
[tex]\frac{6}{\sqrt3}[/tex] * [tex]\frac{\sqrt3}{\sqrt3}[/tex]
This then makes it 6 times root 3 over 3
[tex]\frac{6\sqrt3}{3}[/tex]
We then get [tex]2\sqrt{3}[/tex]

WILL PICK BRAINLIEST! A line l has slope 2. What is the slope of line l1 if l1 ⊥ l ? What is the slope of l2 if l2 ∥ l ?
Answer:
1. The slope of line l1 is -1/2
2. The slope of l2 is 2
Step-by-step explanation:
Perpendicular lines have opposite inverse slopes. The inverse of 2 is 1/2 and the opposite is -2. Therefore the opposite inverse slope of the perpendicular line, l1, is -1/2
When two lines are parallel, the slopes are the same. l2 is parallel to l therefore, they share the same slope.

solve the following equation 3+x upon 3=x upon 2
[tex] \frac{3 + x}{3} = \frac{x}{2} [/tex]
[tex] \frac{3}{3} + \frac{x}{3} = \frac{x}{2} [/tex]
[tex]1 + \frac{x}{3} = \frac{x}{2} [/tex]
[tex]1 = \frac{x}{2} - \frac{x}{3} [/tex]
[tex]1 = \frac{3x}{6} - \frac{2x}{6} [/tex]
[tex]1 = \frac{x}{6} [/tex]
[tex]1 \times 6 = x[/tex]

What is the solution to the equation 6n+7=55
Answer:
n = 8
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
6n + 7 = 55
Step 2: Solve for n
Subtract 7 on both sides: 6n = 48Divide 6 on both sides: n = 8Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: 6(8) + 7 = 55Multiply: 48 + 7 = 55Add: 55 = 55Here we see that 55 does indeed equal 55.
∴ n = 8 is a solution of the equation.

Two health clubs offer different pricing plans for their members. Both health clubs charge a one-time sign-up fee and a monthly membership fee. The graph below represents what Health Club A charges.
The table below represents what Health Club B charges.
Answer:
The answer is below
Step-by-step explanation:
The question is not complete but I would show how this charges can be represented by an equation.
For health club A:
The graph (x, y) passes through the points (2, $136) and (4, $242). Let x represent the total months and y represent the total charges. The equation is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-136=\frac{242-136}{4-2}(x-2)\\\\y-136=53(x-2)\\\\y-136=53x-106\\\\y=53x+30[/tex]
For health club B:
The table (x, y) has the points (4, 173) and (6, 23y). Let x represent the total months and y represent the total costs. The equation is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-173=\frac{237-173}{6-4}(x-4)\\\\y-173=32(x-4)\\\\y-173=32x-128\\\\y=32x+45[/tex]
if <1 and <2 are a linear pair then find the value of x’ if m<1 = 1/3(27x-6) and m<2 = 1/2(6x-20).
Answer:
16
Step-by-step explanation:
Remark
Linear Pair means two angles add to 180. They have a base and a transversal in common.
Equation
1/3(27x - 6) + 1/2(6x - 20) = 180 Remove the brackets
Solution
9x - 2 + 3x - 10 = 180 Collect like terms
12x - 12 = 180 Add 12
12x - 12 + 12 = 180 + 12 Combine
12x = 192 Divide by 12
12x/12/ = 192/12
x = 16

Answer:
y = 2x², 0, 2, 8
y = 2^x, 1, 2, 4
Step-by-step explanation:
For the first equation, multiply the input by itself and then multiply by two
y = 2x²
y = 2(2)²
y = 2(2*2) = 8
For the second equation, multiply 2 by itself depending on the value of the input
y = 2^x
y = 2²
y = 2 * 2 = 4

Three roots of a fifth degree polynomial function f(x) are -2, 2, and 4 + i. Which statement describes the number and
nature of all roots for this function?
A) f(x) has two real roots and one imaginary root.
B) f(x) has three real roots.
C) f(x) has five real roots.
D) f(x) has three real roots and two imaginary roots.
Answer:
D.
Step-by-step explanation:
Its a fifth degree function so it will have 5 roots.
One of the 3 roots is complex ( imaginary):- 4 + i so there must be another root value 4 - i because these roots always occur as conjugate pairs.
The fifth root must be real because you cant have just one imaginary root.
Expand and simplify 2(5x + 3) - 2(2x - 3)
Answer: It is 6x+12
Step-by-step explanation: Distribute 2 to the parenthesis, then do the same at the second parenthesis, 10x+6-4x+6, combine like terms, 10x-4x and +6+6, so 6x+12 is the final result.
