Answer:
Options a, b, c are correct.
Step-by-step explanation:
First let's see the equation that governs the statement, which is the following:
Therefore, reading options a, b, c are correct.
Since from the formula we have the correlation coefficient of two variables x and y and here it shows us the correlation between x, y and y, x is the same.
This means that the 0.4 correlation implies a moderate but positive relationship between the two variables.
that is, the highest or lowest value of one variable implies a highest or lowest value of the other variable, respectively.
Answer:
2116.8 in^3
Step-by-step explanation:
V = l*w*h
All the units need to be the same
Convert 1.4 ft to inches
1.4 ft * 12 inches/ ft = 16.8 inches
V = 14 * 16.8 * 9
= 2116.8 in^3
The answer is 20. Multiply 5/6 by 24 to get 20.
7428. 25+15/4*18+25*12+16*3.
We have to write the system of equations that represents the lunch orders for Dory and Nemo. We have to use x to represent soft tacoes and y to represent Double Deckers. For Dory: 3 x + 3 y = 11.25 and for Nemo: 4 x + 2 y = 10. We cal also oslve this system: 3 x + 3 y = 11.25 ( divide both sides by 3 ); x + y = 3.75; x = 3.75 - y; then we have to put it into the other equation: 4*( 3.75 - y ) + 2 y = 10; 15 - 4 y + 2 y = 10; 2 y = 5; y = 2.50; x = 3.75 - 2.50 = 1.25. Soft tacoes cost $1.25 and Double Deckers cost $2.50. Answer: The system of equations is: <span>3 x + 3 y = 11.25 and 4 x + 2 y = 10.</span>
