Answer:
The correct option is D.
Step-by-step explanation:
The given function is
It is given that the shape of F(x) and G(x) are same.
The transformation is defined as
....(1)
Where, a is horizontal shift and b is vertical shift.
If a>0, then the graph shifts a units left and if a<0,then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0,then the graph shifts b units down.
It is given that G(x) shifted four units left. It means a=4 and b=0.
Substitute a=4 and b=0 in equation (1).
The required function is .
Therefore the correct option is D.
Answer:
0.8808
Step-by-step explanation:
The objective is to calculate the probability of:
P(-1.20 ≤ z ≤ 2.64)
i.e. the probability that is the area between two z-values.
Thus;
P(-1.20 ≤ z ≤ 2.64) = P(z ≤ 2.64) - P( z ≤ 1.20)
From z table;
P(-1.20 ≤ z ≤ 2.64) = 0.9959 - 0.1151
P(-1.20 ≤ z ≤ 2.64) = 0.8808
We can see the shaded area under the standard normal curve from the image attached below.
