Answer:
x = 6√2, y = 6
Step-by-step explanation:
This is an isosceles triangle as one angle measures 45° and the other is a right angle, so it measures 90°.
Therefore, you know that y will equal 6.
You have to multiply a by √2 to find x.
6 x √2 = 6√2

Answer:
35/79
Step-by-step explanation:
Assuming you can't choose the same song a second time, the probability is 35/79.
If you can choose the same song, the probability is 36/80, which reduces to 9/20.
The scale factor for the first one is 2.25
And for the second one it’s 7
I hope this helps :)
Answer:
-1
Step-by-step explanation:
Given: Mean= 25 minutes.
Standard deviation= 2 minutes
x= 23 minutes.
Lets find the z-score for the number of sandwiches delivered in less than 23 mins.
Formula: Z-score= ![\frac{x-mean}{standard\ deviation}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-mean%7D%7Bstandard%5C%20deviation%7D)
Z-score= ![\frac{23-25}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B23-25%7D%7B2%7D)
⇒ Z-score= ![\frac{-2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-2%7D%7B2%7D)
∴ Z-score will be -1
Hence, -1 is the z-score for the number of sandwiches delivered in less than 23 minutes.
