Answer:
1/4
Step-by-step explanation: 1/2*2=1/4
Answer:
1. Scatter plots are used to observe relationships between variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point.
2. A Scatter Analysis is used when you need to compare two data sets against each other to see if there is a relationship. Scatter plots are a way of visualizing the relationship; by plotting the data points you get a scattering of points on a graph

Answer:
The slope of this line is 3.
Step-by-step explanation:
Solve 12x - 4y = 3 for y to obtain the equation in slope-intercept form:
Add 4y to both sides, obtaining 12x = 3 + 4y
Subtract 3 from both sides: 12x - 3 = 4y
Finally, divide all terms by 4: y = 3x - 3/4
The slope of this line is 3.
Answer:
1. 22583.5 J
2. 1248 kg
3. 78.09 m/s
Step-by-step explanation:
The formula for kinetic energy is ;
K.E = 1/2* m * v²
Where m is the mass and v is the velocity
1.
K.E = 1/2 * m*v²
K.E = 1/2 * 47 * 31²
K.E = 22583.5 J
2.
Velocity = 9.78 m/s.
Kinetic energy = 60,800 J
To get mass, apply the formula as;
K.E = 1/2 * m*v²
60,800 = 1/2 * m * 9.78²
60800 = 48.70845 m
60800/48.70845 = m
1248 = m
Mass = 1248 kg
3.
K.E = 143.3 J
Mass = 0.047 kg
Apply the formula;
K.E = 1/2 * m*v²
143.3 = 1/2 * 0.047 * v²
143.3 = 0.0235 v²
143.3/0.0235 = v²
6097.87 = v²
v = √6097.87
v= 78.09 m/s
Suppose x is the total cost for the first purchase, cost of the bread = b and cost of the milk = m
Then:-
y = 5b + 2m
y - 4.2 = 2b + 5m
Subtract:-
4.2 = 3b - 3m
b - m = 4.2 / 3 = 1.4
That is bread costs $1.40 more than the milk. (Answer). Its A
