Answer:

The missing sides are 13 (small) and 2424 (big)

Step-by-step explanation:

The bigger triangle is bigger by 2 so multiply or divide the sides you do know by 2 to find the missing sides.

BC=12

ED= 12*2= 24

FD= 26

AC= 26/2= 13

Answer:

Mean track length for this rock specimen is between 10.463 and 13.537

Step-by-step explanation:

99% confidence interval for the mean track length for rock specimen can be calculated using the formula:

M± $\frac{t*s}{\sqrt{N}}$ where

M is the average track length (12 μm) in the report
t is the two tailed t-score in 99% confidence interval (2.977)
s is the standard deviation of track lengths in the report (2 μm)
N is the total number of tracks (15)

putting these numbers in the formula, we get confidence interval in 99% confidence as:

12± $\frac{2.977*2}{\sqrt{15}}$ =12±1.537

Therefore, mean track length for this rock specimen is between 10.463 and 13.537

Shirley has a credit card that uses the previous balance method. The opening

vesna_86 [32]

Answer:

= $44.19

Step-by-step explanation:

APR = 19%

Billing cycle = 30 days

Balance = $2830

Let's first find the daily rate,

Daily rate = $\frac{0.19}{365} = 0.000521$

The daily rate = 0.000521

To calculate the amount Shirley was charged interest for the billing cycle, we use:

Daily rate * billing cycle * balance

Where,

Daily rate

= $\frac{0.19}{365}$

Billing cycle = 30 days

Balance = $2830

Therefore, expression to be used =

$(\frac{0.19}{365} * 30) * 2830 \\= $44.19$

How to solve 4n-40=7(-2n+2)

Damm [24]

4n-40=7(-2n+2)

4n-40=-14n+14

subtract -4n from both sides

-40 = -18n +14

subtract -14 from both sides

-54=-18n

divide both sides by -18
