Answer:

At least 22 hours in a week.

Step-by-step explanation:

Given: Manuela make $15 per hour.

           Her employers deduct $125 from her weekly check.

           Manuela receives at least $205 in her weekly paycheck.

Lets assume, Manuela working hour in a week be "x".

We know, Total amount on week paycheck= [tex]Hourly\ pay\times number\ of\ hours- Deduction[/tex]

Now, forming an inequality to determine weekly pay of Manuela.

⇒ [tex]15\times x- 125\geq 205[/tex]

⇒[tex]15x-125\geq 205[/tex]

Adding both side by 125

⇒[tex]15x\geq 205+125[/tex]

⇒[tex]15x\geq 330[/tex]

Divinding both side by 15

⇒[tex]x\geq \frac{330}{15}[/tex]

∴[tex]x \geq 22\ hours[/tex]

Hence, Manuela works at least 22 hours per week.

The correlation coefficient between the given variables is determined as 0.771 (three decimal places).

The correlation coefficient between the variables is calculated as follows;

[tex]r = \frac{n\Sigma xy - \Sigma x\Sigma y}{\sqrt{[n\Sigma x ^2 \ - (\Sigma x)^2][n\Sigma y^2- (\Sigma y)^2]} }[/tex]

∑xy = (40 x 6) + (29 x 5) + (108 x 11) + (35 x 7) + (62 x 14) + (50 x 10) + (8 x 2)

∑xy = 3202

n∑xy = 7(3202)

n∑xy = 22,414

∑x = 40 + 29 + 108 + 35 + 62 + 50 + 8 = 332

∑y = 6 + 5 + 11 + 7 + 14 + 10 + 2 = 55

∑x∑y = 332 x 55 = 18,260

∑x² = 40² + 29² + 108² + 35² + 62² + 50² + 8² = 21,738

n∑x²  = 7(21,738) = 152,166

(∑x)² = (332)² = 110,224

∑y² =  6² + 5² + 11² + 7² + 14² + 10² + 2² = 531

n∑y² = 7(531) = 3,717

(∑y)² = (55)² = 3,025

[tex]r = \frac{22,414-18,260}{\sqrt{(152,166-110,224) (3,717 - 3025)} } \\\\r = \frac{4154}{\sqrt{29,023,864} } \\\\r = 0.771[/tex]

Answer:

Step-by-step explanation: y=6 x - 3

(6 X x) - (6 x 3)

6x - 18

-12

The absolute value function y = 6 |x - 3| can be written as a piecewise function. For x < 3, y = 6 * (3 - x) and for x >= 3, y = 6 * (x - 3). This takes into account the always-positive relationship of the absolute value function.

The absolute value function y = 6 |x - 3| can be written as a piecewise function as follows:

This is because the absolute value function defines a relationship where distance is always positive. For values of x less than 3, the expression within the absolute value brackets is negative, so we have to change the sign. For values of x greater than or equal to 3, the expression is already positive, so it stays as it is.

A. The percent error is 12%.

B. If you were to count 84 cars when there were only 75 it would also have the same percent error.

Step-by-step explanation:

Step 1; From the given data I measured the number of cars lower than its actual count. I counted the number of cars as 66 while it was 75. So my measurement was off by 9 counts. My percent error is given by dividing the difference in values by the actual value multiplied by 100.

% error = (difference in values / actual value) × 100

My % error = (75 - 66)/ 75 × 100 = 9/75 × 100 = 12%.

Step 2; My percent error was 13.6363%. I counted the cars lower then there were so to find another similar estimate I just add the percent error to the actual number of cars.

Similar % error = Actual value + 12% = 75 + 12% = 75 + 9 = 84 cars.

Final answer:

To calculate the percent error, use the formula (|Estimated Value - Actual Value| / Actual Value) x 100%. For an estimate of 66 compared to an actual value of 75, the percent error is 12%. An estimate of 84 cars would also produce a 12% percent error because it shares the same distance from the actual value as the original estimate, just in the opposite direction.

Explanation:

The question asks to find the percent error of an estimation and to determine another estimate with the same percent error. To calculate percent error, you use the formula: Percent Error = (|Estimated Value - Actual Value| / Actual Value) × 100%. Applying the given values, we get: Percent Error = (|66 - 75| / 75) × 100% = (9 / 75) × 100% = 12%.

To find another estimate with the same percent error, we can manipulate the percent error formula. Let x represent the new estimate. Thus, 12% = (|x - 75| / 75) × 100%. Solving for x gives two solutions: x = 66 (the given estimate) or x = 84. This means an estimate of 84 cars would also result in a 12% percent error, because it is 9 units away from the actual value, similar to the original estimate.

The reasoning is based on the symmetrical property of the absolute value function used in the percent error calculation, which indicates that the error margin above and below the actual value are equivalent.

percentage, a relative value indicating hundredth parts of any quantity.

Given that a  basketball player made 17 out of 20 free throws at practice

We need to find the percent of the free throws did the player miss.

We find this by finding the product of x/100 with 20 which is equal to 17.

x/100 × 20=17

Now we have to find the value of x which is the percentage.

2x/10=17

0.2x=17

Divide both sides by 0.2

x=17/0.2

x=85%

So, in this case, you can observe that the median of shelter A is 21, and the median of shelter B is 18. That means the median of shelter A is greater than the median of shelter B.

Box plot shows 5 description of the data set it is representing. The true statements for the given data sets' box plots are:

A box plot has 5 data description.

IQR(inter quartile range)  is the difference between third and first quartile.

For the given data set, we see that the middle line of first graph is right to the middle line of the lower graph, thus, Median of B < Median of A (18 < 22) (since as we go right, the magnitude of numbers increases)

Data is symmetric if the median is in the mid of the box plot and the box is mid to the line connecting both whiskers(since then the frequencies are more likely to be distributed symmetric to the middle).

Thus, B is symmetric but A isn't
