Answer:
C. The functions have the same y-intercept
Step-by-step explanation:
In slope intercept form, y = mx + b, b represents the y-intercept, and in the first function the y-intercept is 10.
The y-intercept is when x = 0, and in the chart, when x equals 0, y equals 10.
10 = 10, so they have the same y-intercept.
The answer would be: 5 + 9u
Answer:
The estimate is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 522
The sample proportion of students would like to talk about school is 
Given that the confidence level is 90 % then the level of significance can be mathematically evaluated as



Next we obtain the critical value of
from the normal distribution table, the value is

Generally the margin of error can be mathematically represented as

=> 
=> 
Generally the estimate the proportion of all teenagers who want more family discussions about school at 90% confidence level is

substituting values

Answer:
25
Step-by-step explanation:
if you look at it, 250 is 1/4 of 1000 and 100 is 1/10 of 1000 so divide 250 by 10 and you get your answer.
Answer: half year
Step-by-step explanation:
The formula to find the simple interest is given by :-
, , where P is the principal amount , r is the rate of interest and t is the time in year.
Given : I=420 ; r=14%=0.14 and P =$6000
Then, we have the following equation :-

It means the duration of the loan is half year .
