Provate school in 2005
f(t)=85+18t
public school
g(t)=95+15t
graph
easy
replace g(t) and f(t) with y
y=18t+85
y=15t+95
input values for t and get values for y
y=18t+85
when t=0 y=85
when t=1 y=103
plot the oints (0,85) and (1,103)
y=15t+95
if t=0 then y=95
if t=1 then y=110
plot the points (0,95) and (1,110)
the easier way would just to be to solve the equatons but anyway
interscection point is (3 and 1/3,145)
so after 3 years (2008) it is about 145
Answer:
The correct option is (D).
Step-by-step explanation:
To construct the (1 - <em>α</em>)% confidence interval for population proportion the distribution of proportions must be approximated by the normal distribution.
A Normal approximation to binomial can be applied to approximate the distribution of proportion <em>p</em>, if the following conditions are satisfied:
In this case <em>p</em> is defined as the proportions of students who ride a bike to campus.
A sample of <em>n</em> = 125 students are selected. Of these 125 students <em>X</em> = 6 ride a bike to campus.
Compute the sample proportion as follows:

Check whether the conditions of Normal approximation are satisfied:

Since
, the Normal approximation to Binomial cannot be applied.
Thus, the confidence interval cannot be used to estimate the proportion of all students who ride a bike to campus.
Thus, the correct option is (D).
Answer:
2x = y
Step-by-step explanation:
x is how many bracelets made and each bracelet takes 2 minutes to make so x times 2 or 2x and y is the total time took so 2x=y
