Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
5.2v - (30 ÷ 6) + 12
<u>9) We need to determine which part of the expression represents a quotient?</u>
We know that when we divide one rational expression by another, the result would be termed as 'quotient'.
Here, it is clear that:
(30 ÷ 6) represents the expression part for a quotient.
When we divide 30 by 6, we get the result 5 which would be the quotient of the expression 30 ÷ 6.
10. Which part of the expression represents a product of two factors?
We know that when a multiply two number, we get the product. The multiplying numbers are the factors of the product.
For example, 4 × 9 = 36 therefore, 4 and 9 are the factors of 36.
In our case, 5.2v represents a product of two factors 5.2 and v. In other words, 5.2 and v are the factors of the product of 5.2v.
SOLUTION
b.
c.
So we just have to find the LCM of the denominators, then we perform the rule of addition of fraction
Answer:
0.11
Step-by-step explanation:
Let the random variable score, X = 26; mean, ∪ = 19.6; standard deviation, α = 5.2
By comparing P(0≤ Z ≤ 26)
P(Z ≤ X - ∪/α) = P(Z ≤ 26 - 19.6/5.2)
= P(Z ≤ 1.231)
Using Table: P(0 ≤ Z ≤ 1) = 0.39
P(Z > 1) = (0.5 - 0.39) = 0.11
∴ P(Z > 26) = 0.11
