Answer:

a × b = b × a

Step-by-step explanation:

<u>Communatative Property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer</u>

To help you understand this, let's try switching out the variables for numbers.

Let's say a=3 and b=2

We know that 3 times 2 is 6. By using the Communatative Property we also know that 2 times 3 is 6 (because if we switch the position of the numbers 3 and 2, we would still get the answer 6) So....

3 × 2 = 2 × 3 which would be the same as

a × b = b × a

For a data set of brain volumes (cm3) and IQ scores of eight males, the linear correlation coefficient is found and the P-val

tatiyna

Answer:

The P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is 0.793 which is high so there is not sufficient evidence to conclude that there is a linear correlation between brain volume and IQ score in males.

Step-by-step explanation:

We are given the following information in the question:

p-value = 0.793

Significance level = 0.05

$H_{0}: \mu = \text{ The population correlation coefficient is not significantly different from 0}\\H_A: \mu = \text{ The population correlation coefficient is significantly different from 0}$

Since p value is greater than the significance value so we fail to reject the null hypothesis and accept the null hypothesis. We conclude that there is not a significant linear relationship between two variables.

Thus, we can write:

Answer:

$f(0)=2$

Step-by-step explanation:

Given the function $f(x)=-x+2$ , to find $f(0)$ , simply substitute $x=0$ into the function.

Solving, we get:

$f(0)=-(0)+2=\boxed{2}$

bill has a bike that weighs 56 pounds. Magda has a bike that weighs 52 pounds. she adds a bell and basket to her bike. the bell

serious [3.7K]

Madge's Bike: Since the weight of the bell is 12 ounces, add that to 52 pounds (908 ounces), plus the basket 2 pounds+8 ounces= 2.5 pounds. 908 ounces + 2.5 pounds = 948 ounces. 948 Ounces= 59.25 pounds. 59.25 pounds is greater than 56 pounds. So, Magda's bike with her bell and basket weighs more than Bill's.

{Answer} - Yes, Magdas bike weighs more :)
