Answer: aₙ = -12 + (n - 1) 4
Step-by-step explanation:
aₙ = a + (n - 1) d
a = -12
d = 4
aₙ = -12 + (n - 1) 4
Answer:
a=4
Step-by-step explanation:
ax − 4 = 2y
We need to get the equation is slope intercept form y= mx+b.
Lets solve for y
Divide each side by 2
a/2 x - 4/2 = 2y/2
a/2 x -2 = y
or y=a/2 x -2
The slope is a/2 and the y intercept is -2
We want a slope of 2 so a/2 =2
a/2=2
Multiply each side by 2
a/2 * 2 =2*2
a =4
For 95% CI
x - 0.05s = 100
x + 0.05s = 120
Solve for x and s
The interval for u with 90% is
x - 0.10s
and
x + 0.10s
Substitute x and s
Step-by-step explanation:
sorry dude my last brain cell ran after exam
First you would want to calculate the 20% off the price
20% of $30 is 0.2 x $30 = $6, Then were going to subtract the six dollars from the sweater witch is 30 dollars. So 30 - 6 = 24
The answer is $24
Hope this helps, Good luck! (:
