Answer:
1.28
Step-by-step explanation:
Given a confidence (c) = 0.80
α = 1 - c = 1 - 0.8 = 0.2
α/2 = 0.2/2 = 0.1
From the normal distribution table, The critical value necessary to form a confidence interval is gotten by getting the z value of α/2, which is the same as that of 0.4 (0.5 - 0.1). The z value of α/2 is:
Answer:
Expressing or writing 7+21 as a product of two factors requires the application of Distributive Property
The expression that shows 7+21 written as a product of two factors is
7(1 + 3).
To solve the above question, we apply the Distributive property.
This is expressed as:
a (b + c) = ab + ac
Where
a is the common factor
We are given the expression:
7 + 21
Splitting this into two factors using the distributive property
7 + 21
The common factor for 7 and 21 is 7
Hence, by factorising we have:
7 + 21 = 7(1 + 3)
Therefore, the expression that shows 7+21 written as a product of two factors is :
7(1 + 3)
The correct option is D
Step-by-step explanation:
Answer:
A=8
b=15
c=40
Step-by-step explanation:
5/8 as well as 10/16 = .625
a=8 blocks for 5 min given in question
b:24*0.625=15
c:25*40=.625 or 8 * 5=40 , since 5×5=25 taking 1st column times 5
