Answer:

1. False; 2. False; 3. False.

Step-by-step explanation:

1. Mode

False.

The mode, mean, and media are all measures of central tendency.

The mean is the best measure for normally distributed data.

The median is the best measure for skewed data.

The mode is the least used, because it's the only measure you can apply to nominal data.

2. Median

False.

The mean is the average of a set of scores or list of numbers.

3. Frequency distribution table

False.

It is not necessary to put the numbers in order.

For example, assume that you wanted to count the frequency of occurrence of each number in the list: 3, 0, 1, 4, 4, 1, 2, 0, 2, 2, 0, 2, 0, 1, 3, 1, 2, 1, 1, 3.

If you are doing this manually, you would go through the list and use tally marks to record the appearance of each number in its category.

If you are using a computer, it will do the sorting for you.

The given congruency of the sides $\mathbf{\overline{BE}}$ and $\mathbf{\overline{LO}}$ and $\mathbf{\overline{BO}}$ and $\mathbf{\overline{LE}}$ as well

as the congruency of the common side $\mathbf{\overline{BL}}$ gives.

ΔBEL ≅ ΔLOB by SSS congruency postulate

<h3>Which values correctly completes the table?</h3>

The completed two column proof is presented as follows;

Statement ${}$ Reasons

1. $\underline{\overline{BE} \cong \overline{LO}}$ ${}$ 1. Given

2. $\overline{BO}$ ≅ $\overline{LE}$ ${}$ 2.

3. $\underline{\overline{BL} \cong \overline{BL}}$ ${}$ 3. Reflexive property of congruency

4. ΔBEL ≅ ΔLOB ${}$ 4. SSS congruency postulate

Side-Side-Side, SSS, congruency postulate states that if three sides of

one triangle are congruent to three sides of another triangle, the two

triangles are congruent.

Joan wants to set a 4-digit unlock code for her mobile phone. She plans to use only odd numbers and to make sure that no number

LuckyWell [14K]

Answer: 120

Step-by-step explanation:

There are 5 digits that are odd, 1 3 5 7 9

There are 5 possibilities for the first digit, 4 for the second, 3 for the third, and 2 for the last, so there are 5 x 4 x 3 x 2 = 120

X^2/9+2y/7 help me solve

vfiekz [6]

So firstly, we have to find the LCD, or lowest common denominator, of 9 and 7. To do this, list the multiples of 9 and 7 and the lowest multiple they share is going to be your LCD. In this case, the LCD of 9 and 7 is 63. Multiply x^2/9 by 7/7 and 2y/7 by 9/9:

$\frac{x^2}{9}\times \frac{7}{7}=\frac{7x^2}{63}\\\\\frac{2y}{7}\times \frac{9}{9}=\frac{18y}{63}\\\\\frac{7x^2}{63}+\frac{18y}{63}$

Next, add the numerators together, and your answer will be: $\frac{7x^2}{63}+\frac{18y}{63}=\frac{7x^2+18y}{63}$

Type the correct answer in the box. Use numerals instead of words for numbers.

Blababa [14]

Answer:

x=-16

Step-by-step explanation:

The given equation is:

x = 8a

which was written to find the value of x.

We have to find the value of x when the value of a is inserted as -2

So, putting the value

x = 8(-2)

x= -16

So the value of x when a = -2 is -16 ..
