d=2r= 2·24=48ft
Step-by-step explanation:
Answer:
Type I: 1.9%, Type II: 1.6%
Step-by-step explanation:
given null hypothesis
H0=the individual has not taken steroids.
type 1 error-falsely rejecting the null hypothesis
⇒ actually the null hypothesis is true⇒the individual has not taken steroids.
but we rejected it ⇒our prediction is the individual has taken steroids.
typr II error- not rejecting null hypothesis when it has to be rejected
⇒actually null hypothesis is false ⇒the individual has taken steroids.
but we didnt reject⇒the individual has not taken steroids.
let us denote
the individual has taken steroids by 1
the individual has not taken steroids.by 0
predicted
1 0
actual 1 98.4% 1.6%
0 1.9% 98.1%
so for type 1 error
actual-0
predicted-1
therefore from above table we can see that probability of Type I error is 1.9%=0.019
so for type II error
actual-1
predicted-0
therefore from above table we can see that probability of Type I error is 1.6%=0.016
Answer:
15
Step-by-step explanation:
To find how many she bought, we have to divide. So we do 105/7=15.
Answer:
The standard form of the parabola is 
Step-by-step explanation:
The standard form of a parabola is
.
In order to convert 
into the standard form, we first separate the variables:
we now divided both sides by 2 to remove the coefficient from 
and get:
.
We complete the square on the left side by adding 3 to both sides:
now we bring the right side into the form 
by first multiplying the equation by 
:
and then we multiplying both sides by 
to get
.
Here we see that
Thus, finally we have the equation of the parabola in the standard form:
