Answer:
Step-by-step explanation:
Given that A survey of factories in five northeastern states found that 10% of the 300 workers surveyed were satisfied with the benefits offered by their employers
i.e. sample size n =300
Sample proportion p = 0.10
q=1-p=0.9
Std error =
Margin of error at 95% would be
1.96*std error
= 0.0339=3.39%
5x2y(5 + 20y)
10xy(x + 15y)
10x2(y + 25)
The expression 10x^2y + 25x^2 is an algebraic expression, and the equivalent expression of 10x^2y + 25x^2 is 5x^2(2y + 5)
Equivalent expressions are expressions that have equal values, when evaluated
The expression is given as;
10x^2y + 25x^2
Factor out 5x^2
10x^2y + 25x^2 = 5x^2(2y + 5)
The above means that the equivalent expression of 10x^2y + 25x^2 is 5x^2(2y + 5)

Answer:
Graph is option A
Step-by-step explanation:
3x + 5y = –15
To graph the equation , we need to get y alone
Subtract 3x on both sides
Divide whole equation by 5
To graph this equation , we need to make a table
Plug in some number for x and find out y
x
0 -3
-5 0
Two points on the graph is (-5,0) and (0,-3)
Graph is option A
b) The company takes 600 photos before selecting which ones to use for its calendars.
c) The company expects to sell 600 calendars each month.
d) The company will sell the calendars for $6.00 each.
Answer:
The correct option is a.
Step-by-step explanation:
The average cost function is
Where x is the number of calendars produced.
The average cost formula is
Therefore the total cost is defined b the function
Here 600 is the initial cost and the cost each unit is 2.
Initial cost is the fixed cost which occurs at zero level of productivity.
The company spends $600 on a new computer and printer before beginning the project. The option (a) is correct.
Yes it is true that a functions graph always include solutions that do not appear in its table of values.
An expression in mathematics defines a relationship between one variable (the independent variable, x) and another variable (the dependent variable, y). For example -
f(x) = 4x + 6
Given is a graph of function.
Yes a functions graph always include solutions that do not appear in its table of values. The graph of the function represent all the points that satisfy the function on both sides. The table of values is made just to represent only some of the solutions from the total solutions.
Therefore, yes it is true that a functions graph always include solutions that do not appear in its table of values.

Answer:
a) f(16) = 42
b) f(16) = 54
c) f(16) = 162
d) f(16) = 30
Step-by-step explanation:
a) y = mx + b ∧ m = (f(8) - f(4))/(8-4) ⇒ m = (18 - 6)/(8 - 4) = 3
b = y - mx = 6 - 3(4) = 6 - 12 = - 6
f(16) = 3(16) - 6 = 42
b) y = kxⁿ ∧ f(4) = 6 = k4ⁿ ∧ f(8) = 18 = k8ⁿ ⇒ 18/6 = (k8ⁿ)/(k4ⁿ) ⇒ 3 = 2ⁿ
n = ㏑(3) / ㏑(2) ⇒ k = y/xⁿ ⇒ k = 6/4ⁿ = 2/3
f(16) = 2/3 × 16ⁿ = 54
c) y = aeᵇˣ ∧ f(4) = 6 = aeᵇ⁴ ∧ f(8) = 18 = aeᵇ⁸ ⇒ 18/6 = (aeᵇ⁸)/(aeᵇ⁴) ⇒ 3 = e⁴ᵇ
b = ㏑(3/4) ∧ a = y / eᵇˣ ⇒ a = 6 / e⁴ᵇ = 2
f(16) = 2eᵇ¹⁶ = 162
d) y = a㏑(bx) ∧ f(4) = 6 = a㏑(b4) ∧ f(8) = 18 = a㏑(b8)
⇒ 18 - 6 = a㏑(b8) - a㏑(b4) ⇒ 12 = a㏑(8b/4b) ⇒ a = 12 / ㏑(2)
f(4) = 6 = a㏑(4b) ⇒ b = (√2)/4
f(16) = a㏑(b16) = 30
