Step-by-step explanation:
![\sqrt[4]{81} -2\\=3-2 \\=1](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B81%7D%20-2%5C%5C%3D3-2%20%5C%5C%3D1)
Answer:
The best thing to do here is to put each of these into fractions, with the total (31) as the denominator.
14/31= silver
6/31= black
8/31= copper
3/31= various colours.
As you're looking for the keys that are silver or copper, you've got to add the two denominators together, which gives you 14+8= 22.
This cannot be simplified further, therefore, the probability of choosing either a silver or copper key is 22/31.
Hope this answer helps you :)
Have a great day

Answer:
it is d, step 1: 14x - 21; step 2: 14x=22
Step-by-step explanation:
7(2x-3)=1 1. multiply 7 with (2x) and (-3)
14x-21=1 2. +21 on both sides
14x= 22 3. /14 on both sides
x=1.8
but I will say d is the correct answer
In this question, each star equal to 4 students. If the people on 85 and 90 take the test again that means their number should be 14+4 people= 18 people.
If they all get 95, then it means we need to add 18 people to the 95 graph. The number of stars would be: 18 people / (4people/stars)= 4.5 stars
If you add the stars graph it will be easier. It should be clear that 85 will have 1 stars and 90 have 3.5 stars. Adding them up will be 1 stars + 3.5 stars= 4.5 stars
