Answer:

2 2/3

Step-by-step explanation:

the absolute value is the distance an number is from zero. for example, 1 and -1 are both 1 number away from zero, so both of their absolute values are one.

hope this helps :)

Answer:

2 2/3

Step-by-step explanation:

1) First, find the absolute value of -2 2/3. The absolute value is 2 2/3.

2) Next, convert 2 2/3 to an improper fraction because we want to find the simplest form. The improper fraction is 8/3.

3) Finally, 8/3 cannot be reduced any further, so the answer is 2 2/3.

Hope this helps!

Complete the steps for solving 7 = –2x2 + 10x. Factor out of the variable terms. inside the parentheses and on the left side of

Mamont248 [21]

we have

$7=-2x^{2} +10x$

Factor the leading coefficient

$7=-2(x^{2} -5x)$

Complete the square. Remember to balance the equation by adding the same constants to each side

$7-12.50=-2(x^{2} -5x+2.5^{2})$

$-5.50=-2(x^{2} -5x+2.5^{2})$

Divide both sides by $-2$

$2.75=(x^{2} -5x+2.5^{2})$

Rewrite as perfect squares

$2.75=(x-2.5)^{2}$

Taking the square roots of both sides (square root property of equality)

$x-2.5=(+/-)\sqrt{2.75}$

Remember that

$\sqrt{2.75}=\sqrt{\frac{11}{4}}= \frac{\sqrt{11}}{2}$

$x-2.5=(+/-)\frac{\sqrt{11}}{2}$

$x=2.5(+/-)\frac{\sqrt{11}}{2}$

$x=2.5+\frac{\sqrt{11}}{2}=\frac{5+\sqrt{11}}{2}$

$x=2.5-\frac{\sqrt{11}}{2}=\frac{5-\sqrt{11}}{2}$

<u>the answer is</u>

The solutions are

$x=\frac{5+\sqrt{11}}{2}$

$x=\frac{5-\sqrt{11}}{2}$

A dataset has 1000 records and 50 variables with 5% of the values missing, spread randomly throughout the records and variables.

dusya [7]

Answer: 50

Explanation:

Since 5% of the values are missing, the expected number of records to be removed is interpreted as the expected value of the records to be removed whose probability of having missing values is 0.05.

Hence, the number of records that are expected to be removed is given by

Expected Value = (number of records)(probability of having a missing value)
= (1000)(0.05)
Expected Value = 50

What is the greatest integer value of y for which 5y - 20 < 0?

Anna [14]

5y - 20 < 0...add 20 to both sides
5y < 20...divide both sides by 5
y < 20/5
y < 4 (this states that y is less then 4)

Therefore, the greatest integer that y could be is 3 (because integers cannot be fractions, they have to be whole numbers)
