Answer:
Step-by-step explanation:
-2 = 17
You need find what number that need to be in the blank spot
17 + 2 = 19
19 - 2 = 17
In the second question u need to find equal number
17 - 3 = 16 - 2
14 14
They need to be equal - =
19 - 6 = 18 - 5
13 13

A number is divisible by 3 if the sum of the digits of the number is divisible by 3.This statement is a conditional statement. However, it is not in its standard form. A conditional statement is known as an If-then statement.
It should be written as:
If the sum of the digits of the number is divisible by 3 then a number is divisible by 3.
There are two parts of a conditional statement. The first part is the hypothesis, the second part is the conclusion. The hypothesis starts with "if". The conclusion starts with "then".
The conclusion of the conditional statement is THEN A NUMBER IS DIVISIBLE BY 3.
Answer: You are not comparing two things, and you're asking a question that can only be answered one way.

Answer:
(78, 80)
Step-by-step explanation:
Given a normal distribution :
Mean = 79 seconds
Standard deviation = 0.5 seconds
Using the empirical rule :
95% of her finishing times :
According to the empirical rule, 95% represents 2 standard deviations from the mean that is ± 2 standard deviations from the mean score or value.
Hence ;
The interval will be defined as ;
Mean ± 2(standard deviation)
79 ± 2(0.5)
79 ± 1
(79 - 1) ; (79 + 1)
78 ; 80
