Answer:
Option C is correct.
The exponential grows at twice the rate of the quadratic.
Step-by-step explanation:
Slope(rate) is given by:
As per the statement:
An exponential function and a quadratic function are graphed below.
In the given interval: [0, 1]
In Exponential function graph
Consider points (0, 1) and (1, 2)
then by definition of slope we have;
⇒Rate of exponential function is 2
In Quadratic function graph:
Consider points (0, 0) and (1, 1)
then by definition of slope we have;
⇒Rate of quadratic function is 1
⇒
Therefore, the exponential grows at twice the rate of the quadratic.
Step-by-step explanation:
The plumber's daily earnings have a mean of $145 per day with a standard deviation of
$16.50.
We want to find the probability that the plumber earns between $135 and
$175 on a given day, if the daily earnings follow a normal distribution.
That is we want to find P(135 <X<175).
Let us convert to z-scores using
This means that:
We simplify to get:
From the standard n normal distribution table,
P(z<1.82)=0.9656
P(z<-0.61)=0.2709
To find the area between the two z-scores, we subtract to obtain:
P(-0.61<z<1.82)=0.9656-0.2709=0.6947
This means that:
The correct choice is C.
