Answer:
38.117%
Step-by-step explanation:
Firstly, what you do is to calculate the z-score of both points
Mathematically;
z-score = (x-mean)/SD
where mean = 70 and SD = 5
For 68, z-score = (68-70)/5 = -2/5 = -0.4
for 73, z-score = (73-70)/5 = 3/5 = 0.6
The probability we are to calculate ranges from
P(-0.4<z<0.6) = P(z<0.6) - P(z<-0.4)
it is at this point that we make use of z score table
= 0.38117 which is 38.117%
A is valid
It is the only option where y(-3) and y(4) are both zero
Answer:
Domain: (-∞,∞)
Range: {3}
Step-by-step explanation:
The domain is the x-values of the function, and the range is the y value of the function.
F(x)=3 is really just a fancy way of saying y=3. The range is 3.
Since the function makes a horizontal line, the domain is ∞.
Answer:
y = 3x - 1
Step-by-step explanation:
Answer: first put the equation of the line given into slope intercept form by solving for why you get why equals negative 2X +5 so the slope is negative to perpendicular lines have a opposite reciprocal slopes so the slope of the line we want to find is 1/2 plugging in the point given to the equation why equals 1/2 X plus B and solving Furby we get B equals six
