Answer:
2
Step-by-step explanation:
With regards to the above, we can sum up the foods ate together by the 5 cats, then we have;
= 1/5 + 1/5
= 2/5
Then we can multiply the value above by the 5 cats
= 2/5 × 5
= 10/5
= 2
The cats eat 2 foods together.
Answer:

Answer:
532
Step-by-step explanation:
The score that represents the top 20% = A score = 80%
Z score for 80% percentile = 0.842
We solve using the z score formula
z = (x-μ)/σ, where
x is the raw score = ??
μ is the population mean = 490
and σ is the population standard deviation = 50
Hence:
0.842 = x - 490/50
Cross Multiply
0.842 × 50 = x - 490
x = 0.842 × 50 + 490
x = 42.1 + 490
x = 532.1
Approximately = 532
Therefore, the test score = 532
It’s says error Bc u can’t do 9/0
