In order to solve this, all you have to do is divide 35 by 1.4 (because you need to move the decimal places over to the left two places when changing from a percentage to a decimal.) When you do that, you get 25, so 35 is 140% of 25. I hope this helps! :)
Evelyn has initially $524.96, then she paid $32.50, so she will have less than $500. In order to have at least $500, she needs to deposit the value x.
So the initial value, minus the value paid, plus the deposit needs to be greater than or equal 500, so we have the inequality:
Solving this inequality for x, we have:
Therefore the correct option is the first one (a).
Answer:
D
Step-by-step explanation:
Answer: One sample z test for means
Step-by-step explanation:
From the information given, the sample size is large. It is greater than 30. Again, the population standard deviation is given. This means that the test statistic would be the z score which is determined by the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
The probability value would be determined from the normal distribution table.
Therefore, the hypothesis test that should be used is
One sample z test for means
In order to make a graph, you need an equation.
' 2x - 4y ' is not an equation. Without an equals sign (=)
it's just an expression that stands for a number.
There's nothing in the question that implies a slope,
or an intercept, or even a graph.
