4. Brandon is selling lemonade for $3 dollars each and water bottles
for $1.50 dollars each. He started the day with $3.25 in the cash
register and ended the day with $22.75 in the register.
Write an equation below that represents the relationship between the
amount of money in the register at the end of the day and the
number of lemonades sold, L, and water bottles sold, W.

The confidence interval (12.7%, 24.5%) can be expressed in the form of ˆp ± E,% ± %.

In statistical analysis, a confidence interval is used to estimate the range within which a population parameter, such as a proportion, is likely to fall. In this case, the confidence interval is given as (12.7%, 24.5%). To express it in the form of ˆp ± E,% ± %, we need to determine the point estimate, margin of error, and express them as percentages.

The point estimate, ˆp, represents the best estimate of the population parameter based on the sample data. In this case, it would be the midpoint of the confidence interval, which is (12.7% + 24.5%) / 2 = 18.6%.

The margin of error, E, indicates the amount of uncertainty associated with the estimate. It is calculated by taking half of the width of the confidence interval. In this case, the width is (24.5% - 12.7%) = 11.8%, so the margin of error would be 11.8% / 2 = 5.9%.

Finally, to express the confidence interval in the desired form, we can write it as 18.6% ± 5.9%, 95% ± %. This means that we estimate the population proportion to be within the range of 18.6% ± 5.9% with 95% confidence.

Answer:

340 total people (see below)

Step-by-step explanation:

So first, you need to find the number of children. To do that, the percentage of adults must be 55% because is 45% of 100% are children, the remaining are adults. You can use a ratio to find the amount of children:

x children  =  45%

187 adults     55%

Now, cross multiply:

55x = 187 (45)

55x = 8415

x = 8415/55

x = 153

There are 153 children.

To find the total amount of people in the theater, add the two amounts:

187 adults + 153 children = ? people

                                           = 340 people

The expression for the word problem can be written as x + 12 = 5 ( x - 32).

Lines are perpendicular when they have the reprocial slope with the opposite sign.

Yes, the lines having slopes 6 and -1/6 are perpendicular.

The slope of a line is a number that describes  the direction  of the line. The formula of calculating slope is calculated as under:

Slope=\((y_{2} -y_{1} )/(x_{2} -x_{1} )\).

We have been given that the slope of line A is 6 and slope of line B is -1/6.

Two lines are seem to be perpendicular to each other if the product of their slopes is equal to -1.

Product=slope of line A * Slope of line B

=6*(-1/6)

=-6/6

=-1

Hence the lines having slopes 6 and -1/6 are perpendicular to each other.

Answer:

The correct answer is

b) Below 0

The correct option is (d) To the left of 0.

If the graph for a linear regression crosses the y-axis in negative values, the y-intercept of the regression line would be located to the left of 0 on the y-axis.

Therefore, the correct option is (d) To the left of 0. How to find the y-intercept of the regression line?

The y-intercept of a regression line is the value where the regression line intersects with the y-axis. It is the point where x = 0. In order to find the y-intercept of the regression line, we can use the equation of the regression line, which is y = mx + b. Here, m is the slope of the line and b is the y-intercept.

Therefore, if the regression line crosses the y-axis in negative values, it means that the y-intercept (b) is negative, and the line intersects the y-axis to the left of 0.

Step-by-step explanation:

To determine the maximum amount Jaxson can borrow for a 20-year mortgage with a monthly payment of $1,125 and an annual interest rate of 4.8% (compounded monthly)

We can use the formula for the present value of an annuity:

P = M * (1 - (1 + r)^(-n)) / r

Where:

P = Amount borrowed (to be determined)

M = Monthly payment = $1,125

r = Monthly interest rate = Annual interest rate / 12 = 4.8% / 12 = 0.004

n = Total number of payments = 20 years * 12 months/year = 240

Substituting the given values into the formula:

P = $1,125 * (1 - (1 + 0.004)^(-240)) / 0.004

Calculating the expression inside the parentheses:

(1 + 0.004)^(-240) ≈ 0.354296

Substituting this value into the formula:

P = $1,125 * (1 - 0.354296) / 0.004

P ≈ $1,125 * 0.645704 / 0.004

P ≈ $177,824.75

Therefore, to the nearest dollar, the maximum amount Jaxson can borrow is $177,825.

Answer:

w = 3 cm

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = \(\frac{1}{2}\) bh ( b is the base and h the height )

Here b = 5 and h = 6 , then

A = \(\frac{1}{2}\) × 5 × 6 = \(\frac{1}{2}\) × 30 = 15 cm²

Now the area of the rectangle is 15 cm²

area = length × width , that is

5w = 15 ( divide both sides by 5 )

w = 3 cm

Answer:

2.5

Step-by-step explanation:

equation the two areas in an equation and they are equal

\( \frac{1}{2} base \times height = length \times \: width\)

but the width is w

substituting the values,

\( \frac{1}{2} (6)(5) = 6 \times w \\ 15 = 6w \\ w = \frac{15}{6 =} = \frac{5}{2 } = 2.5\)

The answer is Option 3: log 28.

Logarithm is a mathematical function that is used to determine the exponent of a given number. For example, the logarithm of 8 is equal to 3, since 2 to the power of 3 is equal to 8. Logarithm is also known as log and is commonly used in scientific calculations to simplify complex equations.


This can be derived by using the logarithmic rule of multiplication and addition: log(ab) = log(a) + log(b). In this case, log 4 + log 7 - log 2 = log(4*7) - log 2 = log 28.

The volume of oil exiting the pipe is approximately 100 cu in/hr, 2,400 cu in/day, and 1.39 cu ft/day when converting cu in/day to cubic feet per day.



To calculate the volume of oil exiting the pipe every hour, you would need to know the flow rate of the oil in cubic inches per hour. Let's assume the flow rate is 100 cubic inches per hour.To find the volume of oil exiting the pipe every day, you would multiply the flow rate by the number of hours in a day. There are 24 hours in a day, so the volume of oil exiting the pipe every day would be 100 cubic inches per hour multiplied by 24 hours, which equals 2,400 cubic inches per day.

To convert the volume from cubic inches per day to cubic feet per day, you would need to divide the volume in cubic inches by the number of cubic inches in a cubic foot. There are 1,728 cubic inches in a cubic foot. So, dividing 2,400 cubic inches per day by 1,728 cubic inches per cubic foot, we get approximately 1.39 cubic feet per day.

Therefore, the volume of oil exiting the pipe is approximately 100 cubic inches per hour, 2,400 cubic inches per day, and 1.39 cubic feet per day.

The likelihood of exactly 9 out of 20 students agreeing that online courses provide the same educational value as classroom courses is 18.36%.

To determine the likelihood of exactly 9 out of 20 students agreeing that online courses provide the same educational value as classroom courses, we can use the binomial probability formula.

The binomial probability formula is given by

P(x) = (nCx) * \(p^x\) * \((1-p)^{n-x}\),

where n is the sample size, x is the desired number of successes, p is the probability of success, and (nCx) represents the combination of n objects taken x at a time.

In this case, n = 20, x = 9, and p = 0.40 (as 40% of online students agreed). Plugging these values into the formula, we get

P(9) = (20C9) * \((0.40)^9\) * \((0.60)^{20-9}\).

Calculating this using a binomial calculator or software, the probability of exactly 9 out of 20 students agreeing is approximately 0.1836 or 18.36%.
