Answer:
Step-by-step explanation:
Given:
To determine the equation of the line, we will use point slope form.
<u>Formula of point slope form:</u>
Where "x₁" and "y₁" are the coordinates of the point and "m" is the slope.
Substitute the coordinates and the slope:
Simplify the R.H.S:
Add 1 both sides:
Simplify the equation:
<u>Graphing the line on a coordinate plane:</u>
In this case, we are already given a point (3, 1). We can simply plot the y-intercept ![[\bold{\frac{-1}{5} }]](https://tex.z-dn.net/?f=%5B%5Cbold%7B%5Cfrac%7B-1%7D%7B5%7D%20%7D%5D)
on the coordinate plane. Then, we can draw a straight line through both points. It is suggested that you use a ruler to do so.

Step-by-step explanation: Hmm...
Let's organize this problem.
Since he saved

30
, he as
$
30
Now, that is five-sixths of the total cost of the game.
Let's name the total cost
T
.
If we have a fraction of something, say, half of four, we multiply the fraction by the whole.
half of four
1
2
⋅
4
Similarly, two-thirds of the total can be represented as:
5
6

T
Now, the problem is telling us that
$

is equal to the expression above.
Therefore,
2/3

Answer:
B. The width of the confidence interval would be smaller.
Step-by-step explanation:
By reducing the confidence level from 99% to 95%, the student assumes that there is more uncertainty about the new confidence interval than the previous one. That, being said, since the results aren't as certain, the confidence interval is widened towards a central average point because the new interval isn't as accurate.
Therefore, the answer is B. The width of the confidence interval would be smaller.
