Answer:
A. y-intercept should be (0, -6)
Step-by-step explanation:
The slope-intercept form of the equation for a line is ...
y = mx + b
where m is the slope and b is the y-intercept. These parameters in your equation are ...
m = -3/4
b = -6
This means the y-intercept is at y = -6. Written as an ordered pair, the point is ... (0, -6).
In Step 1, the y-intercept should be (0, -6).
If you want to remember the trig formulas, I suggest the “SOHCAHTOA” or the “Some old hippie caught another hippie tripping on acid method.” It combines all three principle formulas together. So, SOH means sine equals opposite over hypotenuse, and CAH means cosine equals adjacent over hypotenuse, and TOA means tangent equals opposite over adjacent.
Cosine equals adjacent/hypotenuse.
Answer:
a) Interquartile range= upper quartile- lowwr quartile
= Q3- Q1
= 4.75-2.25
= 2.50
b) ( 2.5 ÷ 6 ) × 100
= 41.67%
Answer:
$65.80
Step-by-step explanation:
Divide 26.32 by 8 to find how much is in one gallon.
26.32÷8=3.29
So it's 3.29 per gallon.
Multiply 3 29 by 20.
20×3.29= 65.8
So he would spend $65.80
