Step-by-step explanation:
Find the equation of a line using y = mx + b given the slope is 2 and the y-intercept is (0,2).
Answer:
y=2x+2
Step-by-step explanation:
y=mx+b where:
m=slope; b=y intercept
Therefore, simply plug in values for (m) and (b)
(m=2); (b=2)
and you're left with the equation (y=2x+2)

plastic parts produced by an injection-molding operation are checked for conformance to specifications. each tool contains 12 cavities in which parts are produced, and these parts fall into a conveyor when the press opens. an inspector chooses 3 parts from among the 12 at random. two cavities are affected by a temperature malfunction that results in parts that do not conform to specifications.
The probability that the inspector finds exactly one nonconforming part is 0.4091.
What is combination?Combination is a selection of items from a collection in which the order of selection is irrelevant. Probability is defined as the ratio of favorable outcomes to total outcomes.
Now, according to the question;
Let X represent the event in which the inspector discovers a nonconforming part.
An inspector selects three parts at random from among the twelve, and two cavities have been affected by a temperature malfunction, resulting in parts that do not meet specifications.
The total number of ways to select three parts from a total of twelve is ¹²C₃ = 220.
The number of possible ways for an inspector to identify just one defective part is:
²C₁×¹⁰C₂ = 2×45
²C₁×¹⁰C₂ = 90
The likelihood that the inspector will discover exactly one nonconforming part is provided by:
P (x=1) = (²C₁×¹⁰C₂)/¹²C₃
= 99/220
P (x=1) = 0.4091
The inspector has a 0.4091 chance of finding exactly one nonconforming part.
Now, the probability that inspector finds no nonconforming parts is given by:
P (x=0) = ¹⁰C₃×¹²C₃
= 120/220
P (x=0) = 0.5455
Therefore, the inspector has a 0.5455 chance of finding exactly none nonconforming part.

B) h/15=4/3
C) 15/h=3/4
D) 15/h=4/3
E) 3/15=4/h

For a standard television of width 15 inches the correct options are
A. h/15=3/4, D) 15/h=4/3 and F) 4/15=3/h.
What is ratio ?Ratio is comparison between two or more quantities in simplest form.
The ratio of screen has a width to height ratio of 4:3.
We know a:b can be written as a/b.
∴ width:height = 4:3 can be written as (width/height) = (4/3).
So, Width = (4/3)height or Height = (3/4)width.
Given the height of a standard television is 15 inches.

While shopping kyla found a dress that she would like to purchase but it cost $52.25 mor3 than she has
Kyla should babysit for 9.5 hours to buy the dress.
Double number line represents the comparison of numbers by representing them in equal ratio. The required double number line for the question is attached as figure.
The row I indicates the amount earned and row II indicates the number of hours Kyla should babysit. As is evident from the double number line, the average of last two amounts is the amount required by Kyla. Calculations are as follows -
Required amount = (49.5 + 55)/2
Required amount = 52.25
Now, the time between last two columns of row II will also be taken as average for calculation. So, time required to earn 52.25 after earning 49.5: (9 + 10)/2
Time = 0.5
Total time required to babysit = 9 + 0.5
Total time = 9.5 hours
Thus, Kyla should babysit for 9.5 hours to buy the dress.

Graphing the linear functions, it is found that they will have the same height after 5 hours, of 21 inches.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For each function in this problem, we have that:
The initial height is the intercept.The melting rate is the slope.Hence the functions are given as follows:
A(t) = 51 - 6t.B(t) = 36 - 3t.The functions are graphed at the end of the answer, with A(t) in blue and B(t) in black. The intersection of the graphs is at (5,21), which means that they will have the same height after 5 hours, of 21 inches.

A quarter back is sacked for a loss of 4 yards. On the next play, his team loses 10 yards. Then the the team gains 12 yards on the third play
Answer:
Kindly check explanation
Step-by-step explanation:
Given the question:
Play 1: Quarterback was sacked for a loss of 4 yards
Play 2 : Another loss of 10 yards
Play 3: a gain of 12 yards
Write an addition expression to represent the situation. Then find the sum and explain its meaning.
A loss of 4 yards = - 4
Loss of 10 yards = - 10
Gain of 12 yards = + 12
Addition expression for the scenario :
(-4) + (-10) + 12
Result :
-4 + (-10) + 12
= - 4 - 10 + 12
= - 14 + 12
= - 2
Hence, after two consecutive losses of 4 and 10 yards, the team wins 12 yards on the third play and the aggregate yards lost is reduced to 2 yards.

in class, we proved that the number of ways of tiling a $1 \times n$ rectangle with $1 \times 1$ and $1 \times 2$ tiles is $f {n 1}.$ (a) use a tiling argument to give a combinatorial proof that \[f 1 f 2 f 3 \dots f n
Here is a straightforward recursion you may employ to calculate the value.
let's use rectangles with integer aspects to represent the quantity of tilings of a $2 instances n$ rectangle as $T(n)$. There are $22n-2$ techniques to accomplish this if no rectangles of height $2$ are hired, wherein case we lessen to two wonderful times of the $1 times n$ state of affairs. If no longer, we set a situation based at the top-proper rectangle's $2 height. With the preliminary conditions $T(0)=1$ and $T(1)=2$, this results in $$T(n)=22n-2+sum k=0n-1 T(okay)+sum 0leq k ell leq n-1T(ok)22(n-ell-1)$. The center term inside the recursion corresponds to the case where the rightmost rectangle of top $2$ is absolutely the rightmost rectangle inside the tiling.It should be noted that the formula $2n-1$ for the $1 times n$ case is incorrect if $n=0$.

The Sugar Sweet Company is going to transport its sugar to market. It will cost $3500 to rent trucks plus $225 for each ton of sugar transported. The total cost, C (in dollars), for transporting N tons is given by the following function. C(n)=3500+225n)
Answer:to answer this question you have to look at what the relationship is between tones of sugar and the equation C(n) = 6,500 + 225n. The question gave you a hint in parenthesis in the form of (n) tons. This statement means that the amount of sugar is n so for question 1 the 13 tons is the n value.
Q1:
C(13) = 6,500 + 225*13
C(13) = 6,500 + 2,925
C(13) = 9,425
so what does the 9,425 mean? This is the cost to transport 13 tons of sugar.
Q2:
so this part n is unknown and we are given the C(n) number.
11,450 = 6,500 + 225n
subtract the 6500 from both sides
11,450 - 6,500 = 225n
evaluate
4,950 = 225n
I don't like the n on the right side so I am going to rewrite the equation
225n = 4,950
divide by 225
n = 4,950/225
evaluate
n = 22
So this result means that the company would transport 22 tones of sugar.

WHAT IS BODMAS ?Children can use the acronym BODMAS to help them remember the right order to carry out mathematical operations while solving problems. B-Brackets, O-Orders (powers/exponents or roots), D-Division, M-Multiplication, A-Addition, and S-Subtraction are all abbreviated as BODMAS.
The order of operations (or operator precedence) in mathematics and computer programming refers to a set of rules that represent standards for which operations to carry out first in order to evaluate a specific mathematical expression. For instance, since the advent of contemporary algebraic notation, multiplication has been given a higher priority than addition in mathematics and most computer languages.
As a result, 1 + (2 3) = 7 rather than 1 + (2 3) = 9 is the value assigned to the expression 1 + 2 3. Exponents were first used in the 16th and 17th centuries, when addition and multiplication were given priority. Exponents could only be used as a superscript to the right of their base. Consequently, 3 + 52 = 28 and 3 52 = 75.
