Y = 4x - 7 is a line with a slope of 4 and y-intercept of -7.
plug in any X value, for example 1 and you get the following
y = 4(1) - 7
y = -3
(1,-3) is a point that satisfies the equation y = 4x - 7
The percent of the original price, the new price is given as 86.9%
<u>Solution:</u>
Given, In August, Ralph bought a new set of golf clubs that cost $565.
The cost of the clubs was marked up to $650 in October.
We have to find which proportion can be used to find what percent of the original price the new price is, if p represents the unknown percent?
The formula is normally partial/whole equals to percentage/100. In this case $565 is partial because the price increased.
So it will be,


Whenever you get results like these, you just need to round to the nearest hundredths place, which is 86.9%.
Hence, the percentage is 86.9%

Answer:
B) 0.45
Step-by-step explanation:
The total number of students is:
4 + 5 + 4 + 6 + 10 + 8 + 2 + 1 = 40
The number of students with brown hair is 10 + 8 = 18.
So the probability is:
P = 18/40 = 0.45
