Determine the third side (hypotenuse)
Let the third side be x;
So:

The table of values of the women's age to shoe size is presented as follows;
Women's Age and Shoe Size
[tex]\begin{array}{ccc} Age&&Shoe \, size\\18&&7\\30&&10\\52&&6\\64&&9\end{array}[/tex]
We get;
The correlation coefficient, r, is given as follows;
[tex]r = \dfrac{\sum \left(x_i - \overline x \right ) \cdot \left(y_i - \overline y \right )}{\sqrt{ \sum \left(x_i - \overline x \right )^2 \cdot \sum \left(y_i - \overline y \right )^2}}[/tex]
From MS Excel, we have;
[tex]\sum \left(x_i - \overline x \right ) \cdot \left(y_i - \overline y \right )[/tex] = 2
[tex]\sqrt{ \sum \left(x_i - \overline x \right )^2 \cdot \sum \left(y_i - \overline y \right )^2}[/tex] = √13,000 = 10·√130
∴ r = 2/(10·√130) ≈ 0.01754
Therefore, given that the calculated correlation coefficient, r is positive and less than 0.2 (weak), we have
The correlation is a weak and positive.
Two workers paint lines for angled parking spaces. One worker paints a line so that m∠1=65. The other worker paints a line so that m∠2=65. Are their lines parallel? Explain your answer.
Answers
The image of the car park showing the 2 angles is attached.
Answer:
Their lines are parallel.
Step-by-step explanation:
From the attached image, we can see that ∠1 and ∠2 form a pair of alternate exterior angles. Thus; ∠1 = ∠2.
Now since they are congruent, it means that their lines will be parallel.
Thus, we can conclude that their lines are parallel.

Chef Antonio works at a Latin restaurant and doing a great job. During his yearly evaluation, the owner increased his salary from $42,500 to $46,000. What is the percent of increase, to the nearest whole percent, in Chef Antonio's salary?
Answers
Answer:
8%
Step-by-step explanation:
To find the percent change, we first have to find the amount changed, which is (46000-42500) = 3500. Then, we find what percentage that is of the original amount. Remember that when calculating percentage change, it's important to calculate change with respect to the initial value.
To find the percentage, we can divide 3500 by 42500, and multiply that by 100, resulting in 8 being our nearest whole percent
Alice, Bernice, and Carol have £600 altogether. The ratio of Alice’s money to Bernice’s money is 3:7. Carol has £60 more than Alice. What is the amount of money each girl got?
Answers
Answer:
Alice - £124.62
Bernice - £290.77
Carol - £184.62
Step-by-step explanation:
Let the amount of money Alice has be a. This way, the sentence "The ratio of Alice’s money to Bernice’s money is 3:7." can be translated into a proportion:
Alice's money / Bernice's money = 3 / 7
We can substitute Alice's money with a, and cross multiply and solve for Bernice's money:
a / Bernice's money = 3 / 7
7a = 3(Bernice's money)
Bernice's money = 7/3 a
Now, we can represent Carol's money in terms of Alice's money, she has 60 more, or a + 60. We can create can equation to represent the total:
Alice's money + Bernice's money + Carol's money = total
We can plug in what we have and solve for a:
a + 7/3 a + a + 60 = 600
13/3 a = 540
a = 124.62
This means Alice has £124.62
Bernice has 7/3 a amount of money, so we can substitute the value of a to get Bernice has 7/3 (124.62), or £290.77
We can do the same for Carol who has 60 more, 124.62 + 60 is £184.62
