Answer:
Option 2: 1.5 is the correct answer.
Step-by-step explanation:
Given information is:
Mean = μ = $27
SD = σ = $5.50
A z-score simply tells us how far a selected data value from the mean is.
Z-score is denoted by z and is given by the formula:

Let x = $35.25
Putting the values of mean and SD we get,

The value of z-score for a price of $35.25 per barrel is 1.5
Hence,
Option 2: 1.5 is the correct answer.
Answer:
130
Step-by-step explanation:
<u>Probability of green:</u>
<u>Number of attempts: </u>
<u>Expected number of landing on green: </u>
- <em>Expected frequency = probability × number of trials</em>
<u>Answer: </u>130 times
That's a funky problem... :/ I mean it would depend on how much she earns weekly. If she were working 40 hours each week and earning 10$ an hour then yes, she would have enough. Even is she were per say a student on a part time working 30 hours and earning 8$ per hour, she would still have enough.
To solve this we will divide the given composite figure into three figures. The three figures will be 2 squares and 1 rectangle. Let's find their areas and add them!



<em>Thus, The area of 1st square is 9m²...</em>
- The area of second square will be also 9m², because the sides of both squares are equal.
<h3>
Now area of the reactangle⤵️</h3>
- Length = 6m
- Breadth = 7+3=10m



<em>Thus, The area of rectangle is 30m²....</em>
- Now, Add area of all the figures to get the total area.

<h3><em>Therefore, The total area of the composite figure is 48m²...~</em></h3>
