Question: I see 8 more lilacs than roses. I see 9 roses. How many lilacs do I see? Thanks

harkovskaia [24]

If you see 8 more roses than lilacs, and there are 9 lilacs, then the answer would be 17 lilacs because 8 + 9 = 17. If you were to answer it through algebra, it would be 8 + 9 = x <span />

Textbooks are exempted from PST in Ontario. If the total cost of a book

Andrei [34K]

Answer:

4.24

Step-by-step explanation:

Total price = price of the book + 5% of the price of the book

T = total price P = price of the book G = GST

T = P + G

and

G = 5% of P = 0.05P

therefore

T = P + 5%P = 1P + 0,05P = 1.05P

P = T/1.05 = 89/1.05 ≅ 84.76 (it is 84.7619047619)

G = 89 - 84.76 = 4.24

Consider the following sample data set: 34, 41, 23, 22, 23, 42, 24, 24, 69, 36. What is the standard deviation?

dybincka [34]

Answer:

standard deviation comes out to be equal to 14.63

Step-by-step explanation:

given numbers,

34, 41, 23, 22, 23, 42, 24, 24, 69, 36

arranging in ascending order

22, 23, 23, 24, 24, 34. 36, 41, 42, 69

mean = $\dfrac{22+23+23+24+24+34+36+41+42+69}{10}$

= 33.8

standard deviation = $\sqrt{\frac{\sum (x-\bar{x})^2}{n-1}}$

= $\sqrt{\frac{1927.6}{10-1}}$

= 14.63

hence, the standard deviation comes out to be equal to 14.63
