Xavier and Yolanda both have classes that end at noon and they agree to meet every day after class. They arrive at the coffee sh
Leto [7]

Answer:

\mathbf{ \int_{0}^{10} \int_{y}^{y+45} f(x)g(y)dxdy }

Step-by-step explanation:

Ask yourself, when will Xavier and Yolanda meet??

Firstly, since it is given that Xavier doesn't wait at all, in order for them to meet, Yolanda must arrive before Xavier. This in mathematical terms can be expressed as

Y \leq X

Secondly, Yolanda will wait for only 45 minutes, So Xavier must arrive before that, i.e

X \leq Y+45

Combining both conditions, we obtain

Y \leq X \leq Y+45

If f(x) and g(y) be the density functions for Xavier and Yolanda respectively, the probability of meeting is given by,

\int_{0}^{10} \int_{y}^{y+45} f(x)g(y)dxdy.

hjlf

Answer:

Side known in ratio as 8: 32

Side known in ratio as 9: 36

Side known in ration as 10: 40

Step-by-step explanation:

We can add all the numbers in the ration to form the sum of all the sides, or also equal to perimeter. 8+9+10 equals 27.

So we can write 27x=108

x=4. Multiply 4 to 8, then 9, then 10. You get 32, 36, 40

Hope this helped, Have a Great Day!!
