Answer:
The graph of the parent function is stretched by 4 units.
Step-by-step explanation:
Multiplication of a function by a positive scalar:
When we multiply a function by a positive scalar a, the graph of the function is stretched by a units.
In this question:
g(x) is function f(x) multiplied by 4, which means that the graph of the parent function is stretched by 4 units.
Answer: x^2(1-4x)
Explanation: factor x^2 out of x^2 - 4x^3
Slope of a line = (y2-y1)/(x2-x1)
In this problem:
y2= 1
y1= 0
x2=4
x1= 3
m = (y2-y1)/(x2-x1)
m = (1-0)/(4-3)= 1/1= 1
y= mx+b (line equation)
y-intercept occurs when x=0. So, plug in a point to find b.
I used (4,1)
y=mx+b
y= (1)x+b
1=(1)(4)+b
1=4+b
b= -3
Y-intercepts of the x-axis at (0,-3). Y-intercept= -3

Answer:
Confidence Interval : 2.72% < p < 6.48%
Step-by-step explanation:
Number of randomly selected deaths = 669
Number of deaths caused by accident = 31
z-score for 98% confidence level = 2.326
Confidence Interval : 0.046 - 0.0188 < p < 0.046 + 0.0188
: 0.0272 < p < 0.0648
: 2.72% < p < 6.48%
Hence, Confidence Interval : 2.72% < p < 6.48%
60 people like Ronaldo, and 24 of those 60 people also like Messi.
60-24=36
36 people like Ronaldo only.
