What is the domain, range, and function? {(-3, 3), (1, 1), (0, -2), (1,4), (5, -1)}
wolverine [178]
The domain are all the inputs, that is; the x-values
Domain = { -3, 0, 1, 5}
The range are all the output, that is the y-values
Range = { 3, 1, -2, 4, -1}
This is just a relation and not a function, as we have more than 2 same value of x

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
Answer:
Step-by-step explanation:
<em>Step 1: Consider the assumption:</em>
Generally, 
) is supposed to be the pair of 2 components, in which, the first component is x-component (domain), the second component is y-component (range).
Hence, 
<em>Step 2: Substitute </em>
<em> and </em>
<em> into the inequality</em>
<=> 
<em>Step 3: Simplify</em>
<=> 
<=> 
<em>Step 4: Evaluate</em>
Invalid
Reason: 
<em>Step 5: Conclude</em>
is not a solution to the inequality
Hope this helps!

The number of squares tiles that will be required to floor the rectangular store is approximately 1284 tiles
<h3>How to find the number of tiles used for the rectangular floor?</h3>
The rectangular store measures 6.5m by 7.9m.
Therefore,
area of a rectangle = lw
where
Therefore,
area of a rectangle = 6.5 × 7.9
area of a rectangle = 51.35 m²
The square tiles used for the floor is 20cm each. Therefore,
20 cm = 0.2m
hence
area of the square tile = 0.2² = 0.04 m²
number of tiles = 51.35 / 0.04 = 1283.5
number of tiles ≈ 1284 tiles
