Answer:

22 meters

Step-by-step explanation:

If the penguin goes from 15 meters above sea level to sea level (0 meters), they traveled 15 meters in elevation.

Then they traveled another 7 meters when going 7 meters below sea level.

15 + 7 = 22

Hope this helps :)

Answer:

$\large\boxed{\dfrac{1}{x^2}+x^2=23}$

Step-by-step explanation:

$\left(\dfrac{1}{x}+x\right)^2=25\qquad\text{use}\ (a+b)^2=a^2+2ab+b^2\\\\\left(\dfrac{1}{x}\right)^2+2(x\!\!\!\!\diagup)\left(\dfrac{1}{x\!\!\!\!\diagup}\right)+x^2=25\\\\\dfrac{1}{x^2}+2+x^2=25\qquad\text{subtract 2 from both sides}\\\\\dfrac{1}{x^2}+x^2=23$

Lemon drops and jelly beans are mixed to make a 100 pound mix. if the lemon drops cost $1.90 per pound and jelly beans cost $1.2

vladimir1956 [14]

L = lemon drops

J = jelly beans

L +J = 100

L=100-J

1.90L + 1.20J=1.48*100

1.90(100-j) +1.20J =148

190-1.90J+1.20J=148

190-0.7J=148

-0.7J=-42

J = 60

L=100-60 = 40

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.
