Using it's concept, it is found that the experimental probability of getting a 4 or a 6 is of 0.2833 = 28.33%.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
For an experimental probability, these numbers of outcomes are taken from previous trials.
Researching the problem on the internet, it is found that the image gives that 13 + 11 + 9 + 8 + 10 + 9 = 60 trials, 8 + 9 = 17 resulted in a 4 or a 6, hence the probability is given by:
p = 17/60 = 0.2833.

Answer:
y=x+1
Step-by-step explanation:
To find the line of the equation, use the slope formula to find the slope.
Slope formula is: y2-y1/x2-x1
9-3/6-2= 3/4
Once you have the slope, use that and one of the coordinates to put the equation in point-slope form.
Point-slope form is: y-y1=m(x-x1), with m representing slope and y1 and x1 representing the x and y coordinates.
y-3=1(x-2)
With the equation in point-slope form, you can now distribute 1 to x-2 and simplify to put it in slope-intercept form.
y-3=1x-2
y=x+1
Answer:
Step-by-step explanation:
Given that the housing market has recovered slowly from the economic crisis of 2008. Recently, in one large community, realtors randomly sampled 38 bids from potential buyers to estimate the average loss in home value.
s = sample std deviation = 3000
Sample mean = 9379
Sample size n = 38
df = 37
Std error of sample mean = 
confidence interval 95% = Mean ± t critical * std error
=Mean ±1.687*486.66 = Mean ±821.003
=(8557.997, 10200.003)
a) If std deviation changes to 9000 instead of 3000, margin of error becomes 3 times
Hence 2463.008
b) The more the std deviation the more the width of confidence interval.
