Lisa bowling score is 100.

John bowling score is 282.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

Lisa and John are bowling.

Johns score is three times the difference of Lisa's score and 6.

The sum of their scores is 382.

Now, Let Lisa bowling score = x

Then, John bowling score = 3 (x - 6)

Since, The sum of their scores is 382.

Hence,

x + 3 ( x - 6 ) = 382

After solving,

x + 3x - 18 = 382

4x = 382 + 18

4x = 400

x = 100

Hence, Lisa bowling score = x = 100

And, John bowling score = 3 (x - 6)

                                       = 3 (100 - 6)

                                       = 3 × 94

                                       = 282

Therefore, Lisa bowling score is 100.

And, John bowling score is 282.

In a survey where the ratio of students who prefer muffins to bagels is 4 to 5 and 420 prefer muffins, 525 students prefer bagels.

Ratio is the relationship between two quantities, normally expressed as the quotient of one divided by the other.

It can be expressed in different ways:

1) Use the ":" to separate the values : a : b

2) Use the word "to" : a to b

3) Write it in fraction: a / b

On the other hand, proportion is the equality of two ratios, such that

a : b = c : d

Given a proportion, the product of its means must be equal to the product of its extremes. That is:

ad = bc

If the ratio of students who prefer muffins to bagels is 4 to 5, and 420 students prefer muffins, the proportion can be written as:

4 : 5 = 420 : n

where n = number of students who prefer bagels

Solving for n,

4n = 5(420)

4n = 2100

n = 525

number of students who prefer bagels = 525

None of the above, since the improper fraction 4/3 is identical to the mixed number 1 1/3.

There are various types of fractions, including proper and improper fractions as well as mixed numbers. Mixed numbers: Sometimes converting a mixed number into an incorrect fraction is advantageous or required. If you answer equations that contain both mixed numbers and fractions, you must take this step.

Divide the full integer by the denominator of the fraction (3). (1). 3 x 1 = 3. The product you obtained in the previous step (3) after adding the fraction's numerator (1) is equal to four. 1 + 3 = 4.This turns becomes the improper fraction's numerator.

The answer is 9

Step-by-step explanation:

once we know what the domain and the range of a function is, this is very simple.

the domain is the interval or set of all valid x (input) values.

the game is the interval or set of all valid y (function result) values.

so, what are all the valid x values ? that means for how many months of collection can we use this function to see how many figurines he has ?

well, we can stay with 0 (what he currently has) and go up to 5 (because after 5 months he does not want to continue this behavior).

so, the domain is

0 <= x <= 5 if we allow also fractions of months as input (if this makes sense)

or

x € {0, 1, 2, 3, 4, 5} if we allow only whole numbers.

and the range ? what are the possible result values of the function ?

for x = 0 it starts with y (or f(x)) = 100.

x = 1 gives us 100 + 3×1 = 103

x = 2 gives us 100 + 3×2 = 106

x = 3, 100 + 3×3 = 109

x = 4, 100 + 3×4 = 112

x = 5, 100 + 3×5 = 115

so, the range is

100 <= y <= 115 if we allow fractions of months

or

y = f(x) € {100, 103, 106, 109, 112, 115} if we allow only whole months as values of x.

The critical value that should be used in constructing the confidence interval is ( 1.592, 1.807 ).

Given that;

Number of residents, n = 7

Z*- value of 90% confidence level equals z* = 0.79

Mean x = 1.7 and deviation σ = 0.36

What is the standard deviation?

Standard deviation is calculated as the square root of variance by determining each data point's deviation relative to the mean.

Now,

Number of residents, n = 7

Z*- value of 90% confidence level equals z* = 0.79

Mean x = 1.7 and deviation σ = 0.36

The confidence interval for mean waste recycled per person is

The solution of the given equations is x=-7 and x=3.

The given equation is x² + 5x - 12 = | x + 3| + 7.

A solution is an assignment of values to the unknown variables that makes the equality in the equation true. In other words, a solution is a value or a collection of values such that, when substituted for the unknowns, the equation becomes an equality.

Now, x² + 5x - 12 = | x + 3| + 7 can be rewritten as

x² + 5x - 12 = x + 3 + 7

The slope of the line passing through the given points is 0.4 or 2/5.

From the table given below, we have (2, 23) and (5, 24.3).

Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y-values over the change in the x-values.

Put the points (2, 23) and (5, 24.3) in the slope formula and find the slope.

That is, m=(24.3-23)/(5-2)

=1.3/3

=0.4

=4/10 = 2/5

Put m=2/5 and the coordinate points (2, 23) in y=mx+c.

That is, 23=2/5 (2)+c

⇒23 - 4/5 =c

⇒111/5 = c

⇒ c=22.2

Now, equation is y=0.4m+22.2

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say the first number is a second is b and the third one is c

Now,

The sum of the three numbers is 111

So,

a + b + c = 111

The first number is 9 less than the third

So.

a = c - 9

And the second number is 4 times third

So,

b = 4c

By substitution,

c - 9 + 4c + c = 111

c = 20

b = 4(20) = 80

a = 20 - 9 = 11
