She would have $800 left.
$4000 - $2800= 1200
1200 is how much she spent the last 3 months
1200/ 3= 400
400 * 5= $2000
2800- 2000= $800

Step-by-step explanation:
-23-38=-51
722-8=714
Complete question :
A zoologist is interested in whether climate affects how high kangaroos can jump. In a random sample of gray kangaroos from an Australian forest, he found the mean jump height was x¯=286 inches with a margin of error of 15 inches.
Construct a confidence interval for the mean jump height of gray kangaroos.
Answer:
(271, 301)
Step-by-step explanation:
Given that:
Mean (x¯) = 286
Margin of Error = 15 inches
The confidence interval :
(Mean - Margin of Error), (mean + margin of error)
(286 - 15), (286 + 15)
(271, 301)
Hence confidence interval equals : (271, 301)
Let the final score of White Sox = x
the final score of Marlins = y
White Sox won by 2 runs. Thus
x = y +2
White Sox had twice as many runs as Marlins
x = 2y
From the equations,
2y = y + 2
=> 2y - y = 2
=> y = 2
x = 2y = 2×2 = 4
Hence, final score of
White Sox = 4
Marlins = 2
P, v, and s!
V: for every 3 there is 1
P: for every 3 there is 2
S: because y = x times 2
