Answer:

−25 is 25 units to the left of zero on a number line and

The opposite of −25 is 25 units to the right of zero on a number line.

Step-by-step explanation:

  • a line on which we have numbers from negative infinity till positive infinity is a number line.
  • so, it will obviously have 0 in the middle.
  • in the left we will have negative numbers and on the right of 0 we will have positive numbers.
  • the magnitude of the  numbers will be increasing from 0 on both the sides.
  • see the uploaded image in the attachment for better understanding.
  • so, by seeing the image in attachment, we can say that,

−25 is 25 units to the left of zero on a number line and

The opposite of −25 is 25 units to the right of zero on a number line.

here, opposite of -25 refers to +25, which will be 25 units to the right of zero on a number line.

Scores of an IQ test have a​ bell-shaped distribution with a mean of 100 and a standard deviation of 19. Use the empirical rule
zvonat [6]

Answer: About 99.7%  IQ scores falls within 43 and 157.

Step-by-step explanation:

According to the empirical rule , if a data follows normal distribution then about 99.7% of the population lies with in three standard deviations from mean.

Given:   IQ test have a​ bell-shaped distribution with a mean of 100 and a standard deviation of 19.

Since , the graph of normal distribution is bell-shaped , it mean that IQ scores follow normal distribution.

Then, About 99.7%  IQ scores falls within Mean ± 3 (Standard deviation).

i.e. About 99.7%  IQ scores falls within 100± 3(19).

i.e. About 99.7%  IQ scores falls within 100- 57 and 100+57.

i.e. About 99.7%  IQ scores falls within 43 and 157.

Therefore , by empirical rule

About 99.7%  IQ scores falls within 43 and 157.

Identify all of the following solutions of square root of x minus 8 end root plus 8 equals x.
Anit [1.1K]
\sqrt{x-8} +8=x \\  \sqrt{x-8} =x-8 \\  {( \sqrt{x-8} )}^{2} = {(x-8)}^{2}  \\ x-8= x^{2} -16x+64 \\  x^{2} -16x-x+64+8=0 \\  x^{2} -17x+72=0

(x-8)(x-9)=0 \\ x-8=0 \ and \ x-9=0 \\ x=8 \ and \ x=9
