Answer:
R= {7, 11, 15}
Step-by-step explanation:
Since we already know what the Domain is for f (2, 4, 6) we can use that to get the range
Since the domain is also x let's replace x for 2
y=2(2)+3= 4+3=7
One of the range is 7
Replace x for 4
y=2(4)+3= 8+3= 11
One of the other range is 11
Replace x for 6
y= 2(6)+3= 12+3= 15
The last range is 15
So the range is R= {7, 11, 15}
Answer:
Nope!
Step-by-step explanation:
No, because 9 x 4 = 36, whereas 11 x 3 = 33.

Answer: The minimum score a person must have to qualify for the society = 147.4
Step-by-step explanation:
Let X be the test scores.
As per given,
X is normally distributed.
Mean 


The minimum score a person must have to qualify for the society = 147.4
There two forms to write an equation in; slope-intercept form, <em /><em>y</em> = <em>mx</em> + <em>b</em>, where <em>m</em> is the slope and <em>b</em> is the <em>y</em>-intercept; and point-slope form, which is given by

, where <em>m</em> is the slope and (<em>x</em>₁, <em>y</em>₁) is a point on the line. Given the information and instructions you have I assume you need point-slope form. For #1, you have <em /><em>m</em> = 2 and point (3, 5). Substitute these values in:

If you need slope-intercept form, you start by using the distributive property on what you just wrote:

Now cancel the 5 to isolate <em>y</em>:
