Answer:
A. 64
Step-by-step explanation:
The shoes are 80 dollars. We get a 20% discount
Discount = 80*20%
= 80*.20
=16
The sales price = original price less the discount
= 80 -16
= 64
The answer is 2,-8.
But I am not sure. Hope this will help you!
Answer:
Option 4 is correct
Step-by-step explanation:
Here, we want to select from the options, the dataset that is represented on the histogram
From what we have in the question, there is a range from 60 to 100
Also, there are no terms between 70 and 80
option 1 is wrong as we can see terms between 70 and 80
option 2 is also wrong for this reason
option 3 is incorrect ; looking at the frequency, the numbers between 60 and 70 should be 5 only and we have 6 in that set
Option 4 is the correct answer
NOT a function ......................... :)
The answer is 0.3413 because Explanation:
<span>z=<span><span>x−u</span>σ</span></span>, where <span>u=6 0andσ=10</span>.
Therefore the probability student finish the test between 50 to 60 minutes is,
<span>P<span>(50≤x≤60)</span>=P<span>(<span><span>50−60</span>10</span>≤z≤<span><span>60−60</span>10</span>)</span></span>
<span>P<span>(−1≤z≤0)</span>=P<span>(z≤0)</span>−P<span>(z≤−1)</span></span>
<span>=0.5000−0.1587=<span>0.3413</span></span>
