Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (4, 10) and (x₂, y₂ ) = (2, 1)
m =

= 
Answer:
(5.871 `; 6.127)
Step-by-step explanation:
Given :
Mean = 6
Standard deviation. σ = 0.5
Samplr size, n = 100
Zcritical at 99% confidence = 2.58
The confidence interval :
Mean ± margin of error
Margin of Error = Zcritical * σ / sqrt(n)
Margin of Error = 2.58 * 0.5/sqrt(100) = 0.129
Confidence interval :
Lower boundary = 6.00 - 0.129 = 5.871
Upper boundary = 6.00 + 0.129 = 6.129
(5.871 `; 6.127)
Answer:
3x + 1/2x
Step-by-step explanation:
Just replace "a number" with x

Answer:
$4717.30
Step-by-step explanation:
Assuming the interest is capitalized only at the start of repayment, the accrued interest is ...
I = Prt
I = ($29,300)(0.0322)(4 +1) = $4717.30
The accrued interest is $4717.30.
Since 4 = $3.88
Then 1 = 3.88/4
= $ 0.97
