23x3 is 69
219x6 is 1314
840x 3 2520
3 I'm pretty sure because it can go into both if I remember correctly that's how I was taught
Answer:
57.885
Step-by-step explanation:
For such calculations a probability calculator is very helpful. The one in the attachment shows the 87th percentile to be 57.885.
___
A table of the standard normal distribution will tell you the 87th percentile corresponds to a z-value of 1.12639. Then the X value is ...
X = Zσ +μ = 1.12639(7) +50 = 57.885
Answer:
It is true, except when x = 2/5, since it is an asymptote.
Step-by-step explanation:
3x=5xy-2y
3x=y(5x-2)
3x/5x-2=y
5x-2=0 -------> 5x=2 --------> x=2/5
Answer: f(x) is just a fancy way of writing y in an equation
Step-by-step explanation:
Example: f(x)= 2x+4 is the same as y= 2x+4
