Ok so If 2 of those shapes make one then to find out how many it would need to make 4 you can do this 1 =2 shapes 2 = 4 shapes 3 = 6 shapes 4 = 8 shapes or in this case 2 * 4 = 8 so your answer is 8

You know that you need two already to make one hexagon. So, if you multiply, or add two four times, 2+2+2+2, you would get eight.

Answer:

(d) WEAK NEGATIVE ASSOCIATION.

Step-by-step explanation:

Pearson correlation (r) is defined as a factor which measures the linear dependence between two variables (x and y). It's also known as a parametric correlation.

Here, r = -0.19

Now, as r is NEGATIVE.

⇒ As the value of x increases , value of y decreases.

⇒There is a NEGATIVE ASSOCIATION.

Now as the value of r is between 0 and ( -1). So the factor of variation is very small.

Hence, it is WEAK NEGATIVE ASSOCIATION.

Consider all four-digit numbers that can be made from the digits 0-8 (assume that numbers cannot start with 0). What is the prob

vodomira [7]

Answer:

0.2498

Step-by-step explanation:

Number of 4 digit numbers that can be formed from the digit (0 - 8), assume number can't start from 0

Thus ;

First digit = (1, 2, 3, 4, 5, 6, 7, 8) = 8 ways

Next three digits = (0, 1, 2, 3, 4, 5, 6, 7, 8) = 9 ways

Hence,

Total possible outcomes = sample space = (8 * 9 * 9 * 9) = (8 * 9^3 ) = 8 * 729 = 5832

Required = number greater Than 7000

For number to be greater Than 7000, starting digit should be either 7 or 8

Hence,

First digit = 2 ways

Next three digits = 9 ways

Also excluding 7000

Hence, Number of digits above 7000;

2 * 9^3 = 2 * 729 = 1458 - 1 = 1457

Hence,

Probability = 1457 / 5832

= 0.2498285

= 0.2498

2x +5y=10 writing equations in slope intercept form

rosijanka [135]

Answer: y=-2/5x+2

Solving Steps:
2x+5y=10 - Move the variable to the right
5y=10-2x - Divide both sides by five
y=2-2/5x - Reorder the terms
y=-2/5x+2
