Answer:
25.12/100
Step-by-step explanation:
Percent means per hundred, so 25.12 percent means 25.12 per hundred. Thus, you can make 25.12 the numerator and 100 the denominator, and make 25.12 percent a fraction like this:
25.12/100
Answer:
Step-by-step explanation:
I understand why this was kind tough
the slope of line d is infinite and the slope of line c is zero
so line c 's equation looks like y = 3 ... it's kinda confusing but the line is always 3 so you could pick any x value and y = 3 still. the equation y=3 doesn't rely on x at all to answer it. But x is part of the "frame work" that is implied.
line d is x = 3 , again , y is part of the "frame work" and implied that y doesn't matter in this equations, you always have x = 3 .. or a vertical line , btw. line d does NOT pass the vertical line test , and therefore isn't a function, so the question is wrong, that d will have an equation, b/c there is an implication that d is a function when you say "what is the equation to line d" that is must be a function. But in this case it's not. hm :/ food for thought
A Z-score helps us to understand how far is the data from the mean. The number of phones who have battery life in the range of 11.4 to 13 range is 1145.
<h3>What is Z-score?</h3>
A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,
Where Z is the Z-score,
X is the data point,
μ is the mean and σ is the standard variable.
The percentage of phones who have battery life in the range of 11.4 to 13 range is,
= 0.50 - 0.0228
= 0.4772
Now, the number of phones who have battery life in the range of 11.4 to 13 range is,
Number of phones = 0.4772 × 2400 = 1145.28 ≈ 1145
Hence, the number of phones who have battery life in the range of 11.4 to 13 range is 1145.
