Answer:
x intercept : (6,0)
y intercept : (0,4)
Graph: check attached image.
Step-by-step explanation:
First let's isolate y so that the equation is in slope intercept form , y = mx + b where m is the slope and b is the y intercept
2x + 3y = 12
subtract 2x from both sides
3y = -2x + 12
divide both sides by 3
y = -2/3 + 4
the y intercept is at (0,4) as 4 takes the spot of b which is the y intercept.
To find the x intercept we set y to 0 and solve for x
y = -2/3x + 4
y = 0
0 = -2/3x + 4
subtract 4 from both sides
-4 = -2/3x
divide both sides by -2/3
6 = x
the x intercept is at (6,0)
To graph we put a point at (6,0) as well as (0,4)
We then draw a line through the points.
I recommend you use a ruler.
It should look something like the graph in the attached image.
24 x 10^4, the 4 comes from with how many jumps it took to land on a whole number from 240,000.
Answer:
50 miles
Step-by-step explanation:
x = (30 - 5) / 0.50
<em>Subtract To Solve Parentheses</em>
x = 25 / 0.50
<em>Divide</em>
x = 50
Answer:
a) The third quartile Q₃ = 56.45
b) Variance 
Step-by-step explanation:
Given that :
= 30.8
Median 
= 48.5
Mean = 42
a) The mean is less than median; thus the expression showing the coefficient of skewness is given by the formula :
Divide both sides by 1.38
b) The objective here is to determine the approximate value of the variance;
Using the relation
Variance = 
Answer:
the total amount spent is $31.68
Step-by-step explanation:
The computation of total amount spent as follows:
= 1.4 pounds × $9.15 + 0.8 pounds × $10.75 + 2.6 pounds × $3.95
= $12.81 + $8.6 + $10.27
= $31.68
hence, the total amount spent is $31.68
We simply apply the pounds with its price
