Answer:
If you pick the number 2, you will get (2) - 10 = 8
But the way he said it, it would be: (2) - 2 * 5 = 0
The correct way would be to write the expression: (x - 3) * 5
ANSWER
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
EXPLANATION
The given expression is;
![2 {x}^{ - 4} y](https://tex.z-dn.net/?f=2%20%7Bx%7D%5E%7B%20-%204%7D%20y)
We want to find the value of this expression when x=2 and y=4.
We substitute to get,
![2 {(2)}^{ - 4} (4)](https://tex.z-dn.net/?f=2%20%7B%282%29%7D%5E%7B%20-%204%7D%20%284%29%20)
![8 \times {2}^{ - 4}](https://tex.z-dn.net/?f=8%20%20%5Ctimes%20%7B2%7D%5E%7B%20-%204%7D%20)
Recall that
![{a}^{ - m} = \frac{1}{ {a}^{m} }](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B%20-%20m%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B%20%7Ba%7D%5E%7Bm%7D%20%7D%20)
This implies that,
![8 \times {2}^{ - 4} = 8 \times \frac{1}{ {2}^{4} }](https://tex.z-dn.net/?f=8%20%20%5Ctimes%20%7B2%7D%5E%7B%20-%204%7D%20%20%3D%208%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B%20%7B2%7D%5E%7B4%7D%20%7D%20)
![8 \times {2}^{ - 4} = 8 \times \frac{1}{16 } = \frac{1}{2}](https://tex.z-dn.net/?f=8%20%20%5Ctimes%20%7B2%7D%5E%7B%20-%204%7D%20%20%3D%208%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B16%20%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20)
Answer:
f(g(x)) = (x+3)^2
Step-by-step explanation
Take the function f(x) and replace the x in this function with g(x)
f(x) = x^2 and replace with x=x+3
f(g(x)) = (x+3)^2
Answer:
Step-by-step explanation:
1. 882/24 = 36.75 or 37 crates of milk
2. 3712 x 6 = 1902 yoghurts were sold
3. 94291 - 63512 = 30779
4. 91429 is greater by (91429-42929) = 48500.
10. 7 hours 55 mins
1 month and 3 days or 33 days.

Answer:
The probability you see a dolphin or a whale on both days is 0.64
Step-by-step explanation:
Consider the provided information.
It is given that the brochure claims an 80% chance of siting a dolphin or a whale.
The provided claims can be written as: 80% or 0.80
Let say first day you see a dolphin or a whale and same happen on the next day.
Thus, the probability is:
0.80 × 0.80 = 0.64
Probability of see them on both days is 0.64
Hence, the probability you see a dolphin or a whale on both days is 0.64
