Answer:

0.9+0.01+0.007

Step-by-step explanation:

We are asked to write 0.917 in expanded form.

We can see that our given number has 9 tenths, 1 hundredths and 7 thousandths.

To write our given number in expanded form, we will write each digit according to its place value as:

0.917=0.9+0.01+0.007

Therefore, the expanded form of our given number would be 0.9+0.01+0.007.

WILL GIVE BRAINLIEST
Triss [41]

Answer:

(-10, 0) and (0,-5)

Step-by-step explanation:

For the function f(x)=-\dfrac{1}{2}x-5, find x-intercept and y-intercept:

1. when y=0, then

0=-\dfrac{1}{2}x-5,\\ \\\dfrac{1}{2}x=-5,\\ \\x=-10;

2. when x=0, then

y=-\dfrac{1}{2}\cdot 0-5,\\ \\y=-5.

You get two points (-10, 0) and (0,-5). Plot them on the coordinate plane and connect, obtained line is the graph of the linear function f(x)=-\dfrac{1}{2}x-5.

A random sample of 12 recent college graduates reported an average starting salary of $54,000 with a standard deviation of $6,00
Marianna [84]

Answer: a.) $50188 to $57812

Step-by-step explanation: <u>Confidence</u> <u>Interval</u> (CI) is an interval of values in which we are confident the true mean is in.

The interval is calculated as

x ± z\frac{s}{\sqrt{n} }

a. For a 95% CI, z-value is 1.96.

Solving:

54,000 ± 1.96.\frac{6000}{\sqrt{12} }

54,000 ± 1.96\frac{6000}{3.464}

54,000 ± 1.96*1732.102

54,000 ± 3395

This means the interval is

50605 < μ < 57395

<u>With a 95% confidence interval, the mean starting salary of college graduates is between 50605 and 57395 or </u><u>from 50188 to 57812$.</u>

<u />

b. The mean starting salary for college students in 2017 is $50,516, which is in the confidence interval. Therefore, since we 95% sure the real mean is between 50188 and 57812, there was no significant change since 2017.
