makkiz [27]

Answer:

if you mean like an example, cooking instructions, if they ask for a certain amount of time for this many of the item, but not the amount you want, you can use another example of time to find unit rate then figure out how long you need to cook it for with your desired number of items

How do you write -6 3/4 as a decimal and what is -6 3/4 as a decimal?

6.75 because 6 is the whole number so it won't change and if you do 3 divided by 4 you get .75

Select the graph that matches the function y= 3x + 7

Molodets [167]

Answer:

The first graph.

Step-by-step explanation:

The graph of the function y = 2x + 7, is a straight line because it is a linear function, and has y-intercept of 7 and a slope of 3; so we are looking for a graph that has these characteristics.

From the 4 graphs, we see that the 1st graph has a slope of 3 and a y intercept of 7, and thus it is the correct answer.

Using the normal distribution, it is found that there is a

a) 0% probability that the number of calls received at the switchboard will be exactly 578.

b) 0.1586 = 15.86% probability that the number of calls received at the switchboard will be less than 570.

c) 0.9485 = 94.85% probability that the number of calls received at the switchboard will be between 561 and 600.

<h3>Normal Probability Distribution</h3>

In a <em>normal distribution</em> with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

It measures how many standard deviations the measure is from the mean.

After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem:

The mean is of 580, hence $\mu = 580$ .

The standard deviation is of 10, hence $\sigma = 10$ .

Item a:

In the normal distribution, the probability of an exact value is 0%, hence, 0% probability that the number of calls received at the switchboard will be exactly 578.

Item b:

The probability is the <u>p-value of Z when X = 570</u>, hence:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{570 - 580}{10}$
