Answer:
The total value of her stock after three days = $ 2796.3
Step-by-step explanation:
Total number of shares = 117
Total value of shares = $ 2614.95
Value of increase of one share in one day = $ 1.01
Total value increase of 117 shares in one day = 117 × 1.01 = $ 118.17
Total value increase of 117 shares on second day = 117 × 0.11 = $ 12.87
Total value increase of 117 shares on third day = 117 × 0.43 = $ 50.31
Total value of stock after three days = $ 2614.95 + $ 118.17 + $ 12.87 + $ 50.31
⇒ $ 2796.3
This is the total value of her stock after three days.
Answer:
4 and -5 for the first one
-5 and -5 for the second
5 and -4 for the third
-4 and 5 for the fourth
Step-by-step explanation:
i think you missed a decimal place for 8.5°
when temperatures drop it means minus
so
-7.5-5-8.5= -21°
Answer:
A) sample mean = $1.36 million
B) standard deviation = $0.9189 million
C) confidence interval = ($1.93 million , $0.79 million)
*since the sample size is very small, the confidence interval is not valid.
Step-by-step explanation:
samples:
- $2.7 million
- $2.4 million
- $2.2 million
- $2 million
- $1.5 million
- $1.5 million
- $0.5 million
- $0.5 million
- $0.2 million
- $0.1 million
sample mean = $1.36 million
the standard deviation:
- $2.7 million - $1.36 million = 1.34² = 1.7956
- $2.4 million - $1.36 million = 1.04² = 1.0816
- $2.2 million - $1.36 million = 0.84² = 0.7056
- $2 million - $1.36 million = 0.64² = 0.4096
- $1.5 million - $1.36 million = 0.14² = 0.0196
- $1.5 million - $1.36 million = 0.14² = 0.0196
- $0.5 million - $1.36 million = -0.86² = 0.7396
- $0.5 million - $1.36 million = -0.86² = 0.7396
- $0.2 million - $1.36 million = -1.16² = 1.3456
- $0.1 million - $1.36 million = -1.26² = 1.5876
- total $8.444 million / 10 = $0.8444 million
standard deviation = √0.8444 = 0.9189
95% confidence interval = mean +/- 1.96 standard deviations/√n:
$1.36 million + [(1.96 x $0.9189 million)/√10] = $1.36 million + $0.57 million = $1.93 million
$1.36 million - $0.57 million = $0.79 million
Answer:
8 cards
Step-by-step explanation:
19 + 5 = 24
24/3 = 8
