The raised price represents 110% of the original price (100% plus the extra 10%)
A percentage is converted into a decimal multiplier by dividing by 100:
To clarify the final stage, consider this (where
is the original price):
From here, basic algebraic rules make solving for
easy:
Therefore the original price of a ticket was $175
Answer:
A. The approximate y intercept appears to be about 1.8 (slightly less than 2). What this tells us is that someone with 0 months of practice could expect to win around 1.8 games.
B. Using slope intercept form and assuming that the y intercept is at (0, 1.8), the equation can be solved for by finding the slope first and then putting the slope and the y intercept into the equation.
Slope (m):
points (0, 1.8) and (1, 3.0)
(Y2-y1)/(x2-x1)=(3.0-1.8)/(1-0)=1.2/1=1.2
Equation:
Y=mx+b
Y=1.2x+1.8
Step-by-step explanation:
8x^2+5x=-3
8x^2+5x+3=0
after solving this u will get x= (- 5(⁺ ⁻)√-71)/16
Answer:
(1,7)
Step-by-step explanation:
Put the point (1,7) in y=2x+5
or, 7= 2×1+5
or, 7=7
which is true.
To solve this using probability simply count the shapes that have at least 4 sides, and represent it as a fraction among all shapes in the spinner.
P(4 sides) = 5/6.
P(tails) = 1/2.
Both are independent events and as such must be multiplied with each other.
5/6 • 1/2 = 5/12,
This is the combined probability of both events occurring.
