Answer:

9 hours worked after school and 4 hours worked on saturday

Step-by-step explanation:

x = amount of hours worked after school

y = amount of hours worked on saturday

x + y = 13 or x = 13 - y

and

3x + 4y = 43

plug:

3 · (13 - y) + 4y = 43

39 - 3y + 4y = 43

y = 4

plug:

x = 13 - y

x = 13 - 4 = 9

9 hours worked after school and 4 hours worked on saturday

Answer:

О A = 10°

Step-by-step explanation:

∡ DBC = 180 - 130 = 50°

∡ DBC + ∡ CBD + ∡ BCD = 180°

50° + 70° + ∡BCD = 180°

∡BCD = 180° - (50°+70°)

∡BCD = 180° - 120°

∡BCD = 60°

Then:

∡BCD - ∡DBC = 60° - 50° = 10°

Using the Factor Theorem, the length of one side of the garden is:

(3x - 4) feet.

The Factor Theorem states that a polynomial function with roots \(x_1, x_2, \codts, x_n\) is given by:

\(f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)\)

In which a is the leading coefficient.

The area of a rectangle is given by the multiplication of it's dimensions. In this problem, it is given by:

A = 9x² - 24x + 16.

The root of 9x² - 24x + 16 = 0 is x = 4/3 with multiplicity 2, hence:

\(x_1 = x_2 = \frac{4}{3}\)

Hence the area can be written as:

\(A = 9\left(x - \frac{4}{3}\right) \times \left(x - \frac{4}{3}\right)\)

Then, to find one side:

9(x - 4/3) = 9x - 12 = 3(3x - 4).

Hence (3x - 4) feet is one side.

Step-by-step explanation:

Answer:

x = 1

Step-by-step explanation:

4x+7(3x-3) = 9-5x (equation)

4x+21x-21 = 9-5x (simplify)

25x-21 = 9-5x (combine like terms)

30x-21 = 9 (add 5x to each side)

30x = 30 (add 21 to each side)

x = 1 (divide each side by 30)

To find the mean paycheck, we'll first calculate the sum of all the paychecks and then divide it by the total number of paychecks.

Sum of paychecks = (0 * 3) + (1 * 5) + (2 * 4) + (3 * 2) + (4 * 1)
                               = 0 + 5 + 8 + 6 + 4
                               = 23

Total number of paychecks = 3 + 5 + 4 + 2 + 1
                                               = 15

Mean paycheck = Sum of paychecks / Total number of paychecks
= 23 / 15
≈ 1.5333 (rounded to four decimal places)

The mean paycheck is approximately $1.53.

Since the calculated mean paycheck is between $1 and $2, it falls under the "1" stem. This makes the mean a two-digit number starting with "1." Therefore, the mean is a two-digit number starting with "1."

The mean paycheck indicates that the typical student in the sample makes around $1.53 per month.

The statement A confidence interval for proportions is used to estimate the population proportion not the sample proportion is true.

A confidence interval for proportions is a statistical tool used to estimate the range of values within which the population proportion is likely to lie. It is calculated based on the sample proportion, sample size, and a specified level of confidence.

The sample proportion is only used as a point estimate of the population proportion, but the confidence interval takes into account the variability of the sample proportion and provides a range of values that are likely to include the population proportion with a certain level of confidence.

The amount left is an illustration of equivalent expressions.

All three expressions can be used to represent the amount left

The given parameters are:

\(\mathbf{Paycheck =X}\)

\(\mathbf{Savings =20\%}\)

The amount left is:

\(\mathbf{Amount = Paycheck \times (1 - Savings)}\)

So, we have:

\(\mathbf{Amount = X\times (1 - 20\%)}\)

Substitute 250 for A

\(\mathbf{Amount = 250 \times (1 - 20\%)}\)

Express percentage as decimal

\(\mathbf{Amount = 250 \times (1 - 0.20)}\)

\(\mathbf{Amount = 250 \times 0.80}\) ---- this represents option (A)

Expand \(\mathbf{Amount = 250 \times (1 - 20\%)}\)

\(\mathbf{Amount = 250 - 250 \times 20\%}\)

\(\mathbf{Amount = 250 - 250 \times 0.20}\) ---- this represents option (B)

Express 250 as X in \(\mathbf{Amount = 250 - 250 \times 0.20}\)

\(\mathbf{Amount = X - X \times 0.20}\) ---- this represents option (C)

Hence, all three expressions can be used to represent the amount left

The hypothesis that the mean responses for value for the dollar and customer service do not differ by gender was tested in the Excel file cell phone survey.

In the cell phone survey Excel file, a hypothesis was tested to determine if there was a difference in the mean responses for value for the dollar and customer service based on gender. The survey data was analyzed using appropriate statistical methods, such as t-tests or analysis of variance (ANOVA), to compare the mean ratings between male and female respondents.

To test the hypothesis, the Excel file data was first organized to separate the responses based on gender. Then, the mean ratings for value for the dollar and customer service were calculated for both male and female respondents. Statistical tests were performed to determine if there was a significant difference between the two groups.

The results of the hypothesis test will indicate whether there is evidence to support or reject the claim that the mean responses for value for the dollar and customer service do not differ by gender. If the p-value associated with the statistical test is below a predetermined significance level (e.g., 0.05), it would suggest that there is a significant difference between the mean ratings for the two genders. On the other hand, if the p-value is greater than the significance level, it would indicate that there is insufficient evidence to conclude a difference in mean responses.

Answer:

108

Step-by-step explanation:

Let's assume that there are "x" scouts attending the jamboree.

The number of tins of soup required to feed x scouts would be x/2.

The number of tins of frankfurters required to feed x scouts would be x/3.

The number of tins of fruit required to feed x scouts would be x/4.

Therefore, the total number of tins required to feed x scouts would be:

x/2 + x/3 + x/4 = (6x + 4x + 3x) / 12 = 13x/12

Since we know that 117 tins were opened, we can set up the equation:

13x/12 = 117

Solving for x, we get:

x = 108

Therefore, there were 108 scouts attending the jamboree.

Using the properties of parallelograms and the given information, we proved that BAEC is equal to FABC. We utilized angle-angle similarity and the proportional relationships of corresponding sides in similar triangles to establish the equality.

To prove that BAEC = FABC, we will use the properties of parallelograms and the given information.

Given:

ABCD is a parallelogram.

BE is parallel to CD.

BF is parallel to AD.

To prove:

BAEC = FABC

Proof:

Since ABCD is a parallelogram, we know that opposite sides are parallel and equal in length. Let's denote the length of AB as a, BC as b, AD as c, and CD as d.

Since BE is parallel to CD and AD is parallel to BF, we have angle ABE = angle CDF and angle ADB = angle BFD.

By alternate interior angles, angle CDF = angle FAB.

Now, we have two pairs of congruent angles: angle ABE = angle CDF and angle ADB = angle BFD.

Using angle-angle similarity, we can conclude that triangle ABE is similar to triangle CDF and triangle ADB is similar to triangle BFD.

As the corresponding sides of similar triangles are proportional, we have the following ratios:

AB/CD = AE/CF (from triangle ABE and triangle CDF similarity)

AD/BC = BD/CF (from triangle ADB and triangle BFD similarity)

Cross-multiplying the ratios, we get:

AB * CF = CD * AE (equation 1)

AD * CF = BC * BD (equation 2)

Adding equation 1 and equation 2, we have:

AB * CF + AD * CF = CD * AE + BC * BD

Factoring out CF, we get:

CF * (AB + AD) = CD * AE + BC * BD

Since AB + AD = CD (opposite sides of a parallelogram are equal), we have:

CF * CD = CD * AE + BC * BD

Simplifying, we get:

CF = AE + BC

Therefore, we have shown that BAEC = FABC.

By using the formula for the volume of a cylinder, we will see that the volume of the mug is 502.4 cm^3

For a cylinder of radius R and height H, the volume is:

V = pi*R^2*H

In this case, we know that H = 10cm, and the diameter is 8cm, then the radius is half of that:

R = 8cm/2 = 4cm

Replacing that in the volume equation we get:

V = 3.14*(4cm)^2*10cm = 502.4 cm^3

Answer: After t seconds, Fred is far away from Mark by (45-t).

Step-by-step explanation:

Given: Mark gives Fred a 45meter head start.

After t seconds, the distance of  Fred from the starting point = 5t+45

The distance of Mark from the starting point = 6t

Now, Distance between Fred and Mark after t seconds = Location of Fred - Location of Mark

= (5t+45)-6t

= 5t+45-6t

= 45-t

Hence, After t seconds, Fred is far away from Mark by (45-t).
