700,000 is your final answer so the number was rounded to the hundred thousands value/place.
Wow, what a coincidence, I just learned this at school today!
1. Slope
M= yb-ya/xb-xa
M= 8-4/8-6
M= 4/2
M= 2
2. Y-intercept
Y= mx + b
4 = (2)(6) + b
4 = 12 + b
4 = 12 + b
-12 = - 12 + b
-8 = b
Therefore, the equation is Y = 2x - 8
Answer:
1. $1.60
2. gallon
Step-by-step explanation:
Each gallon of lemonade would cost $1.60.
The rate is $1.60 per gallon.
Hope it helps!
1 nickels =$0.05
1 dime= $0.1
let the number of nickels be x and that of dimes be y.
total number of coins is given by:
x+y=42
hence:
y=42-x.......i
total amount of cash will be:
0.05x+0.1y=3.30.........ii
substituting i in ii we get:
0.05x+0.1(42-x)=3.30
0.05x+4.2-0.1x=3.3
-0.05x=-0.9
x=-0.9/(-0.05)
x=18
hence the the number nickels is x=18, the number of dimes will be y=42-x=42-18=24
1. Mean.
2. <span>Standard deviation.
First we have to square each value and calculate the mean of that squares:
so the variance:
and the standard deviation:
