Answer:

2.25km

Step-by-step explanation:

Calculate the total distance:

The walker has travelled 9km, so

11.25km - 9km = 2.25km left

REALLY NEED HELP: The Venn Diagram shows a universe with 26 elements and two different outcomes: B and Y

Goshia [24]

Answer:

P(B|Y)=0.4

Step-by-step explanation:

We are given with a Venn diagram of a universe with 26 elements and two different outcomes: B and Y

And we are asked to find P(B|Y)

The formula for P(B|Y)= $\frac{P(B\cap Y)}{P(Y)}$

From Venn diagram, $P(B\cap Y)=\frac{n(B\cap Y)}{26} =\frac{8}{26} =\frac{4}{13}$

And P(Y)= $\frac{n(Y)}{26}=\frac{8+12}{26}= \frac{20}{26}= \frac{10}{13}$

Hence P(B|Y)= $\frac{(\frac{4}{13})}{\frac{10}{13}} =\frac{4}{10}=0.4$

DaniilM [7]

Work backwards.

After she put half of what she had left in, she had 17.76.

Multiply by 2:

17.76 * 2 = 35.52

Add 25:

35.52 + 25 = 60.52

Add 14.48:
