Answer 1

Answer:

Putting the numbers in order;

Mid-term numbers: 100 100 100 95 95 92 92 88 85 75

Median = (95 + 92) / 2 = 93.5

First quarter = Q1 = 100 100 100 95

Median of first quarter = (100 + 100) / 2 = 100

Third quarter = Q3 = 92 88 85 75

Median of third quarter = (88 + 85) / 2 = 86.5

Interquartile range (IQR) can be calculated bysubtracting Q3 from Q1;

IQR of mid-term = 86.5 – 100 = -13.5

Now putting the final term numbers in order;

Final-term numbers: 98 95 93 91 88 82 78 78 65 60

Median = (88 + 82) / 2 = 85

First quarter = Q1 = 98 95 91 88

Median of first quarter = (95 + 91) / 2 = 93

Third quarter = Q3 = 78 78 65 60

Median of third quarter = (78 + 65) / 2 = 71.5

Interquartile range (IQR) can be calculated bysubtracting Q3 from Q1;

IQR of final-term = 71.5 – 93 = -21.5

Thus the IQR of mid-term is the largest.

in one baseball season, peter hit twice the difference of the number of home runs alice hit and 6. altogether, they hit 18 home runs. hohw many home runs did each player hit that season?

Answers

Let Peter's hit be x and Alice's runs be y.
x = 2(y - 6) . . . (1)
x + y = 18 . . . (2)

Putting (1) into (2) gives,
2y - 12 + y = 18
3y = 18 + 12 = 30
y = 30/3 = 10
x = 2(10 - 6) = 2(4) = 8

Therefore, Peter hit 8 home runs and Alice hit 10 home runs.

Name the property of -4x-1/4=1

Answers

point slope formula is what to believe

Final answer:

The property of this equation is the distributive property of multiplication over addition or subtraction.

Explanation:

The property of the equation -4x - 1/4 = 1 is called the distributive property of multiplication over addition or subtraction. Using this property, we can distribute the coefficient -4 to both terms inside the parenthesis. This gives us -4x - 4(1/4) = 1. Simplifying further, we have -4x - 1 = 1. To isolate the variable x, we can add 1 to both sides, which gives us -4x = 2. Finally, dividing both sides by -4, we find that x = -0.5.
