An equation shows the equal value of two expressions while an inequality shows that an expression is either less than or more than the other; an equation shows equality, inequality shows inequal
Answer:
The cardinality is 6.
Step-by-step explanation:
The cardinality of a set is a measure of the number of elements in the set. The set S has 6 elements, characters as listed, therefore we say the cardinality of the set S is 6, or |S|=6.
Answer:
-4
Step-by-step explanation:
-4(-4) + 5 > 17
16 + 5 = 21 > 17
Answer:
6
Step-by-step explanation:
This is calculated as using z score
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Hence,
We find the z score of 95.44% confidence interval
95.44% = 1.9991
Hence.
1.9991 = ( X = 22) - (X = 10)
1.9991 = (22 - 16/ σ) - (10 - 16/ σ)
1.9991 = (6/σ - (-6/σ)
1.9991 = ( 6/σ + 6/σ)
1.9991 = (6 + 6/σ)
1.9991 = 12/σ
Cross Multiply
= 1.9991 × σ = 12
σ = 12/1.9991
= 6.00270121555
Approximately 6
Hence, the standard deviation is 6
