A car is purchased for 28,000 after each year, the resale value decreased by 25% what will be the resale value be after 3 years?
alisha [4.7K]

Answer:

11,812.5

Step-by-step explanation:

25% = 0.25

(YEAR ONE)

28,000*0.25 -- > 21,000

↓ (why?)

28,000 * 0.25 = 7,000

28,000 - 7,000 = 21,000

(YEAR TWO)

21,000 * 0.25 -- > 15,750

↓ (why?)

21,000 * 0.25 = 5250

21,000 - 5,250 = 15,750

(YEAR THREE)

15,750 * 0.25 -- > 11,812.5\\

↓ (why?)

15,750 * 0.25 = 3,937.5\\15,750 - 3,937.5 = 11,812.5

Answer = 11, 812.5

You want to estimate the mean weight loss of people one year after using a popular weight-loss program being advertised on TV. H
maria [59]

Answer:

At least 6907 people.

Step-by-step explanation:

Population std deviation = sigma= 10.6

Since population std deviation is known, we can use normal probability table to get sample size from confidence interval.

The sample mean weight loss is within 0.25 lb of the true population mean.

Hence  margin of error < 0.25

Margin of error = z critical (std dev/n) where n = sample size

Z critical for 95% = 1.96

Hence 0.25 >1.96(10.6)/sq rt n

Simplify to get

sq rt n > 1.96(10.6)/0.25 = 83.104

Square both the sides to get

n > 83.104 square = 6906.27

i.e. sample size should be atleast 6907.

The m6 = (11x + 8)° and m7 = (12x – 4)° What is the measure of 4? m4 = 40° m4 = 48° m4 = 132° m4 = 140°
bezimeni [28]
M< 6 = m< 7 (vertical angles)
11x + 8 = <span>12x – 4
12x - 11x = 8 + 4
 x = 12
so
m< 6 = </span>11x + 8 
m< 6 = 11(12) + 8
m< 6 = 132 + 8
m< 6 = 140

m<4 = 180 - m<6
m<4 = 180 - 140
m<4 = 40

answer

<span>m<4 = 40</span>
