Ronique recorded the number of games that the school softball team won each year for the past 7 years: 31, 24, 32, 22, 34, 28, 38. Ronique's team won at least (blank)
games in 75% of the seasons that they played.

Answers

Answer:

Ronique's team won at least 24 games in 75% of the season that they played.

Step-by-step explanation:

(The box-whisker plot below will show everything, but I'll explain it in detail because I want to be more helpful)

So... we have seven data points.

2014 - 15 (Year 1): 31 wins

2015 - 16 (Year 2): 24 wins

2016 - 17 (Year 3): 32 wins

2017 - 18 (Year 4): 22 wins

2018 - 19 (Year 5): 34 wins

2019 - 20 (Year 6): 28 wins

2020 - 21 (Year 7): 38 wins

We need a box & whisker plot for this.

22 will go on the left whisker, since it's the lowest of the data points. 38 will go on the right whisker, since it's the highest.

For the two quartiles, 24 is the first quartile, so from that point to the right whisker, that's 75% of the data. The third quartile will be 34. And the midline will be at 31, since it's the median of the data points.

From that explanation, we can be sure that Ronique's team won at least 24 games in 75% of the seasons that they played.

Originally, a department store bought a set of dishes at a cost of $57.68 and marked it up 125%. After a month, the set of dishes had not sold, so the store marked it down 50%. What was the discounted price?

Answers

Answer:

$64.89

Step-by-step explanation:

57.68 + 1.25 × 57.68

= 57.68 + 72.1

= 129.78

The original price was $129.78.

129.78 – 0.50 × 129.78

= 129.78 – 64.89

= 64.89

The discount price was $64.89.

What is the value of y in the equation 4y - 2(1 - y) = -44?
-23
-15
оооо
-14
-7

Answers

Answer: -7

Explanation:
4y-2(1-y)=-44
Distribute: 4y-2+2y=-44
Combine like terms: 6y-2 = -44
Simplify: 6y = -42
Y = -7

An unknown number y is 15 more than an unknown number x. The number y is also x less than 8. The equations to find x and y are shown below.

y = x + 15
y = −x + 8

Which of the following statements is a correct step to find x and y?

and could somebody please give me a step by step explanation

Answers

Since both equations equal y, you can combine them to x+15=-x+8
Next you need to move both variables to the same side so you can subtract x from both sides so it would be 15=-2x+8
Now you want to get the variable alone so you’d subtract the 8 from each side of the equation and you’d be left with 7=-2X
Lastly you one just one x so divide each side by -2 and you’d have 7/-2=x
x= -7/2 or -3.5

Let me know if you want further explanation of how I got x.

Answer:

x = −3.5

y = 11.5

Step-by-step explanation:

y = x + 15

y = −x + 8

[We know that y is 15 units more than x, and that −x is 8 units less than y. That can be combined into −x + 8 = x + 15 for the first variable (x), and for the second variable (y), y − 15 = −y + 8]

↓

In order to solve this, solve for the first variable in one of the equations, then substitute the result into the other equation.

↓

x = −[tex]\frac{7}{2}[/tex] = −3.5

y = [tex]\frac{23}{2}[/tex] = 11.5
