Answer:
The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
Step-by-step explanation:
We have given,
The sample size n=42
The sample mean 
The population standard deviation 
Let 
be the level of significance = 0.05
Using the z-distribution table,
The critical value at 5% level of significance and two tailed z-distribution is
The value of margin of error is
The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
Parenthesis first so, 64/8(10)+5, next 64/8 because it's division and it's first, 8(10)+5, next is 8(10) so 80+5, lastly 80+5 is 85.
Answer:
The photo has the answers.
Step-by-step explanation:
A coin flip results in 2 different ways: heads or tails. The letter at the top of the vertices of those lines represent the side one is going for. The outcomes are the same: either heads or tails.
Answer:
Meiling's Dog
Step-by-step explanation:
Determine how much each dog eats per day by dividing the amount in pound by the number of days given.
Charlotte's Dog = 10.5/12 = 0.875pounds per day
Meilings Dog = 15/16 = 0.9375pounds per day
Amelia's Dog = 4/6 = 0.67pounds per day
Zahra's Dog = 6/8 = 0.75pounds per day
Therefore,
Meilings Dog with 0.9375 pounds per day is the answer
Or you can do the easy way
convert to slope intercept
y=mx+b
m=slope
get 1y all by itself
8x-4y=8
minus 8x both sides
-4y=-8x+8
divide both sides by -4
y=2x-2
y=mx+b
slope is 2
the hack way is
for an equatoin in standard form
ax+by=c
slope=-a/b
slope=2
if you want to graph 2 points and do it the long way, here it is
if x=0, y=-2
if y=0, x=1
(0,-2) and (1,0)
slope=(y2-y1)/(x2-x1)
slope=(0-(-2))/(1-0)=2/1=2
slope is 2
