Answer:
Volume = 315 cm³
Step-by-step explanation:
Volume = Length × Width × Height
→ Substitute in the values
Volume = 6 cm × 3.5 cm × 15 cm
→ Simplify
Volume = 315 cm³
Answer: 24
Step-by-step explanation:
Number of marbles in jar = 32
Let blue marbles be represented by b.
Since there are three times as many green marbles as blue. This means that green will be = 3 × b = 3b
We then add them together. This will be:
3b + b = 32
4b = 32
b = 32/4
b = 8
There are 8 blue marbles
Since green is 3× blue. Therefore,
Green = 8 × 3 = 24 marbles
Y=3x
x-2
The correct answer is y=6
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.
