Answer:
4th choice
Step-by-step explanation:
Let f(x)=x^4 be the parent function.
This is what the following means:
n(x)=(x-3)^4 : The parent function has moved right 3.
h(x)=-x^4 : The parent function has been reflected over the x-axis.
------------------
Together (n and h):
m(x)=-(x-3)^4: The parent function has been reflected over the x-axis and moved right 4 units.
----------------
v(x)=(x-3)^4+5: The parent function has been moved right 3 units and up 5 units.
So you have g(x)=-(x+3)^4.
So this consists of a reflection across x-axis and has been shifted 3 units left.

Answer:
A) Probability that the error is less than 0.2 mm; P(X < 0.2) = 0.0272
B) Mean Error (E(X)) = 0.6
C) Variance Error (V(X)) = 0.04
D) Answer properly written in attachment (Page 2)
E) P(0<X<0.8) = 0.8192
Step-by-step explanation:
The probability density function of X is;
f(x) = { 12(x^(2) −x^(3) ; 0<x<1
So, due to the integral symbol and for clarity sake, i have attached all the explanations for answers A - D.
E) The probability that the specification for the error to be between 0 to 0.8 mm is met will be;
P(0<X<0.8) = F(0.8) − F(0) =12([(0.8)^(3)] /3] −[(0.8)^(4)]/4]
= 0.8192
So, the probability is 0.8192.
Step-by-step explanation:
Given
5x + 2x + 2 = 9x + 4
9x - 5x - 2x = 2 - 4
9x - 7x = - 2
2x = - 2
x = - 2 / 2
Therefore x = -1.
Answer: The probability is 1/4
Step-by-step explanation:
The odds of rolling a 1,2, or 3 on the first roll is 3/6 or 1/2.
The odds of rolling a 4,5, or 6 on the second roll is also 3/6 or 1/2
The odds all together is 1/4 because 1/2 divided by 1/2 is 1/4.

Answer:
69 candy bars
Step-by-step explanation:
No. Of candies he had=420
No. Of candies he ate=351
No of candies left=420-351=69
