If you're paying attention in your statistics class, you know that about 68% of the data lies within one standard deviation of the mean. That is, between
.. 20.6 -2.2 = 18.4
and
.. 20.6 +2.2 = 22.8
Selection A is appropriate.
Answer:
yes
Step-by-step explanation:
$60×25%=$15...so the coupon she have worth $15 but she also have $50
so she has an overall of $65 she can use
but she must pay sales tax:$60×6,75%=$4.05
so then the overall money that she must pay for the printer is $60+$4.05=$64.05
so then the difference of her money and the price of the printer is:
$65-$64.05=$0.95
$0.95 is left over
1/3 divided by 2 is 1/6. Just half 1/3.
Answer:
Step-by-step explanation:
Given the number 8.132132....
we have to convert the above number to a rational expression.
→ (1)
Multiply by 1000 on both sides
→ (2)
Subtracting equation (1) from equation (2), we get
Divide throughout by 999, we get
which is required rational form.
Answer:
Option b) is the answer
Step-by-step explanation:
A function from X₁ to Y₁ is an object f such that every x in X₁ is uniquely associated with an object f(x) = y in Y₁.
Then
1(b)f={(5,25),(10,5),(15,5),(20,10),(5,25)} is the correct answer.
It follows that
f(5) = 25
f(10) = 5
f(15) = 5
f(20) = 10
