Answer:

The slope is -2

Step-by-step explanation:

(-4,6) (3,-8)

((-8) - (6)) / ((3) - (-4))

(-8 - 6) / (3 + 4)

Answer:

Q4 = 4 || Q5 = 6 2/3 || Q6 = 4 4/7 || Q7 = 10 || Q8 = 3 1/3 || Q9 = 4 1/2

Step-by-step explanation:

In order to divide fractions, you just have to turn it into multiplying!
Flip the second fraction in the number sentence and then multiply!

Example: 5 divided by 6/7

Keep 5 as it is. Flip 6/7 to 7/6. 5 x 7/6 = 35/6

Now, simplify it! Simplifying is very simple. You just have to divide until they can't be divided anymore.

35/6 simplified = 5 5/6.

Reason:

How many 6's are in 35? 5 R: 5

So, then it would be 5 5/6.

Hope this helped and this was correct! If you have any more questions, I'll be here to answer them!

The number of violent crimes committed in a day possesses a distribution with a mean of 2.3 crimes per day and a standard deviat
marusya05 [52]

Answer:

B) approximately normal with mean 2.3 and standard deviation 2

Step-by-step explanation:

Given the following :

Mean crimes per day = 2.3

Standard deviation = 2

Number of samples = 100

Sampling distribution of the mean:

According to the central limit theorem:

Sample mean = population mean

2.3 = 2.3

The standard deviation of the sample (s) : ratio of the population standard deviation and square root of the sample size.

s = population standard deviation / √sample size

s = 2 / √100

s = 2 / 10

s = 0.2

The central limit theorem also posits that once ths sample size is large enough, the sampling of the sample mean will be approximately normal.

Hence, the distribution is approximately normal, with mean of 2.3 and standard deviation of 0.2
