Answer:
Jennifer used $24-14=10 dollars in total.
The $10 was spend on five pens, each pen costing say, x, dollars.
The equation would be 10 = 5x
x = 10÷5= $2
So each pen costs $2 :)

Answer:
The upper limit of the 95% confidence interval is:
C.I_u = 200 + (58.8/
)
Step-by-step explanation:
The formula is given as:
C.I = μ ± Z*σ/
The upper limit => C.I_u = μ + Z*σ/
The lower limit => C.I_l = μ - Z*σ/
The sample size (n) is not stated in the question. Hence, we calculate the upper limit with respect to n.
The upper limit => C.I_u = 200 + 1.96*(30/
)
= 200 + (1.96*30)/
= 200 + 58.8/

Answer:
The total number of matches expected to be won by Lakewood Wildcats in this season is 20.
Step-by-step explanation:
The number of games played by Lakewood Wildcats = 7
Number of matches won by Lakewood = 5
or, the ratio of Won : Played = 5: 7
Total numbers of games in the season = 28
Let the Lakewood Wildcats win m number of games.
Here, ratio of Won Matches : Played Matches = m : 28
Now, by RATIO OF PROPORTIONALITY:

⇒
or, m = 20
Hence, the total number of matches expected to be won by Lakewood Wildcats out of total 28 matches is 20.
