Answer: -2x^2+16x-24 ==> Option 3
Step-by-step explanation:
f(x) = x - 6 and g(x) = -2x + 4
f(x) • g(x)=(x-6)*(-2x+4)=
-2x^2+4x-(-12x)-24=
-2x^2+4x+12x-24= -2x^2+16x-24 ==> Option 3
The answer is 14 when rounded to the nearest whole number, to get this you simply must divide 43 by 3 which equals to 14.333.
Answer: The correct answer is: [D]: "8" .
Step-by-step explanation:f y varies inversely with x; then y = k/x ; with "k" being the "constant" in this equation.
You can find the constant by substituting the values given: x = 16, f(x) = y = 2 ;
So, f(x) = y = 2 = k/16 ;
→ 2 = k / 16 ;
Solve for the constant; "k" ;
Multiply EACH SIDE of the equation by "16"
→ 16* (2) = (k / 16) * 16 ;
→ 32 = k ;
↔ k = 32 ;
As such, we can write the equation:
y = k/ x ; as:
→ y = 32/ x ;
Since we are given: "x = 4" ; Plug in that value; and solve for "y" ;
y = 32/4 = 8 .
y = 8 .
y = f(x) ;
So; f(x) = 8 ; which is: Answer choice: [D]: "8" .
Answer:
Step-by-step explanation:
Given
---- the average
-- standard deviation
Required
The 1st to 3rd quartile
Since the distribution is normal, then:
i.e.
So, we have:
Rewrite Median as Q2
To solve for Q1 and Q3, we use the following formula
Multiply both sides by 2
Substitute
Also, we have:
----- quadrants are equidistant
Rewrite as:
Substitute:
Make Q3 the subject
Substitute in
Collect like terms
Divide by 2
