Which expression shows the distance on the number line between −7 and 16?
a) |−16−(−7)|
b) |−7+16|
c) |7−16|
d) |−7−16|
Final answer:
The correct expression to find the distance on the number line between -7 and 16 is |16 - (-7)|, which equals 23 units. The distance is always a positive number.
Explanation:
The expression that shows the distance on the number line between −7 and 16 is |16 - (-7)|.
To find the distance between two points on a number line, subtract one point from another and take the absolute value of the result. This ensures the distance is positive, as distance cannot be negative. Hence, the correct expression is:
|16 - (-7)| = |16 + 7| = |23| = 23
So, the distance between the points is 23 units.
The probability of an outcome that lies within 68% of the mean is a good indicator that it lies in which standard deviation? A. There is a probability that the outcome is within 3 standard deviations of the mean. B. Standard deviations are not reliable, so the probability cannot be determined. C. There is a probability that the outcome is within 2 standard deviations of the mean. D. There is a probability that the outcome is within 1 standard deviation of the mean.
Answer:
D. There is a probability that the outcome is within 1 standard deviation of the mean.
Step-by-step explanation:
The correct answer is an option (D) There is a probability that the outcome is within 1 standard deviation of the mean.
What is standard deviation?"It is a measure of the amount of variation of a set of values from is mean."
What is mean?"It is the average of all the set of values."
What is empirical rule?"It is a statistical rule which states that - For a normal distribution, the observed data will fall within three standard deviations of the mean.""This rule predicts that 68% of observations falls within the first standard deviation.""95% of observations falls within the first two standard deviations.""99.7% of observations falls within the first three standard deviations."For given question,
According to empirical rule,
The probability of an outcome that lies within 68% of the mean is a good indicator that it lies in the first standard deviation.
Therefore, the correct answer is an option (D) There is a probability that the outcome is within 1 standard deviation of the mean.

A fraction is a way to describe a part of a whole. The correct option is D.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
To arrange the given fraction simply the given fraction as shown below.
3/4 = 0.75
1/4 = 0.25
7/16 = 0.4375
5/8 = 0.625
Since it can be seen that the points are arranged on the number line, therefore, the first point will have the least value, while the last point will have the maximum value.
Therefore, each point can be written in the fraction form as,
A = 0.25 = 1/4
B = 0.4375 = 7/16
C = 0.625 = 5/8
D = 0.75 = 3/4
Hence, A=1/4,B=7/16,C=5/8,D=3/4.

Joseph says that in the number 9,999,999,all the digits have the same value?Is Joseph correct? explain
Joseph is not correct.
What is place value?- Any number formed from some digits, each digit has a place value.
- For example : 1,234 this number formed from 4 digits
The place value of 4 is ones ⇒ 5
The place value of 3 is tens ⇒ 40
The place value of 2 is hundreds ⇒ 300
The place value of 1 is thousands ⇒ 2,000
1,234= 1,000 + 200 + 30 + 4
Now the given number is 9,999,999
Now the place value of each digit is given as,
∵ The number formed from 7 digits
- The place value of the leftmost digit is millions
- The place value of the digit before the million is hundred thousands
- The place value of the digit before the hundred thousands is
ten thousands
- The place value of the digit before the ten thousands is thousands
- The place value of the digit before thousands is hundreds
- The place value of the digit before hundreds is tens
- The place value of the digit before tens is ones
∴ 9,999,999 = 9,000,000 + 900,000 + 90,000 + 9,000 + 900
+ 90 + 9
∴ Each digit from the leftmost digit is ten times the digit before it
Hence, Joseph is not correct.
