To determine the total cost of the books, multiply the amount per book with the number of books. In this example, each book costs one pound and ninety-five pence. Converting 95 pence to pound gives 0.95 pounds. Therefore, the cost of each book is 1.95 pounds. Multiply this amount by six, we get 11.7 pounds. Thus, six books cost 11 pounds and 70 pence.
Answer:
All real number greater than equal to zero.
Step-by-step explanation:
The function is given by
The domain is defined as the input values so that the function is well defined.
here, the values of x should be all real number and zero also.
So, the correct option is (d).
Answer:
20.92
Step-by-step explanation:
Given the data:
X : 170, 160, 130, 165, 125
Standard deviation (s) :
s = √Σ((X - m)² / n)
m = mean
n = sample size
Mean , m = Σx/n
m = (170 + 160 + 130 + 165 + 125) / 5
m = 750/5
m = 150
((X - m)² / n - 1)
[(170-150)^2 + (160-150)^2 + (130-150)^2 + (165-150)^2 + (125-150)^2] / (5-1)
= 1750 / 4
= 437.5
s = √437.5
s = 20.9165
s = 20.92
last week because, the class that week was only 1 hour and last weeks was 3/2 an hour
7.6375 =
1 Decimal Place = 7.6
<span>2 Decimal Place = 7.64
</span><span>3 Decimal Place = 7.638
</span><span>4 Decimal Place = 7.6375
</span>
So the answer is 7.64 .
The 3 rounds up because 7 is bigger than 5...
