Answer:
110.8. This is only for 24÷5 +18-12-400+500. I don't know the answer to the last two numbers.
Step-by-step explanation:
Answer:
3/4 liter per hour
Step-by-step explanation:
1/2=2/3x (multiply by 3 to get 2x)
1 1/2 = 2x (divide by 2 to isolate)
3/4 = x
3/4 liters per hour
Answer:
Linear equations use one or more variables where one variable is dependent on the other. Almost any situation where there is an unknown quantity can be represented by a linear equation, like figuring out income over time, calculating mileage rates, or predicting profit. Many people use linear equations every day, even if they do the calculations in their head without drawing a line graph.
Answer:
A
Step-by-step explanation:
You want to select the scatter plot with strong positive correlation.
<h3>Correlation</h3>
Correlation is a measure of how well one variable's values track the values of another variable. Perfectly correlated variables will have a scatter plot that is a straight line. The sign of the correlation (positive, negative) matches the sign of the slope of the line.
The less correlated values are, the more their scatter plot looks like a random placement of points. When there is no correlation at all, knowing the value of one of the variables gives no clue about the value of the other one.
Computed values of correlation range from -1 to +1.
<h3>Strong positive correlation</h3>
When the plot begins to resemble a line with positive slope, the variables plotted in the scatter plot have strong positive correlation. That is shown in the attached scatter plot.
Answer:
I can't think of an answer for 29 and 30, but the answer to 28 should be 53.
Step-by-step explanation:
A triangles maximum angle is 180. If angle Q is 90 degrees and angle R is 37. 90+37 is 127. Then, 180-127 is 53.
