The correct answer would be D. The plot of the line 5x+2y = 8 is slanted right downwards. To predict, we write the equation into slope-intercept form as follows:
y = mx + b where m is the slope and b is the y-intercept form
5x + 2y = 8
y = -5x/2 + 4
As we can see, the slope is negative so the graph should slope to the right downwards.
Answer:
The lower bound for a 90% confidence interval is 0.2033
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
90% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The lower bound for a 90% confidence interval is 0.2033
GG easy
I=(r)(t)(P)P=principalr=rate in decimalt=timei=interest
so just plug in what you know to solve for what you don't know
first oneI=(0.05)(3)(100)
I=15
2nd one20=(0.04)(t)(500)20=20tdivide by 20 both sides1=tt=1
3rd one35=(0.10)(7)(P)35=0.70Pdivide both sides by 3550=PP=50
4th one6=(r)(2)(200)
6=400rdivide both sides by 4000.015=rconvert to percent1.5%=r
