If a number is (blank), then the number is less than its absolute value

Mathematics
1 answer:
monitta3 years ago
5 0
The absolute value is always either a zero or a positive number.
Therefore:
If a number is negative, then the number is less than its absolute value.

Examples to better illustrate this:
1- If a number is "0", then its absolute value is also "0" (number is equal to absolute value)
2- If a number is "25", then its absolute value is also "25" (number is equal to absolute value)
3- If a number is "-25", then its absolute value is "25" (number is less than its absolute value).

Please help I forgot how to do it :P
Naily [24]

Answer:

25%

Step-by-step explanation:

$115 - $92 = $23 (first blank)

To do the fraction it is the new amount/the original amount

23/92

divide 23 and 92

23/92 = 0.25 (second and third blank)

0.25 x 100% = 25%

A model rocket is 3 inches long. The real rocket is 120 feet long.
Nana76 [90]

The units are the complete story on this question. All of the choices are over 1 so the units make the answer over one. It takes more feet than it does inches to make the scale. The correct units are 120 feet / 3 inches. That makes A and B both incorrect.

You can't get 360 by any method but multiplication. The units for multiplication would be ft*in. So D is wrong. That only leaves you with C which is the answer.

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.
