Answer:
x = 1.6
Step-by-step explanation:
0.6x + 1.3x = 3.04
1.9x = 3.04
x = 3.04/1.9
x = 1.6
9 apples per basket
Peter is making 8 identical fruit baskets. If the baskets are identical, that means they all have the same amount of fruit in them. If I know how many apples were used, then I can divide that by the total number of baskets (8) to find out how many apples were used per basket.
12 oranges were used per basket. There were 8 baskets. 12 x 8 = 96, so 96 oranges were used in total.
168 - 96 = 72
There were 72 apples used in total.
There were the same amount of apples in each of the 8 fruit baskets. 72/8 = 9, which means that there were 9 apples per fruit basket.
Answer:the fraction of the total parade vehicles that are motorcycles is 2/9
Step-by-step explanation:
Let x represent the total number of parade vehicles.
Two thirds of the parade vehicles were vintage vehicles. This means that the total number of vintage vehicles would be
2/3 × x = 2x/3
1⁄3 of the vintage vehicles were motorcycles. This means that the total number of motorcycles would be
1/3 × 2x/3 = 2x/9
Therefore, the fraction of the total parade vehicles that are motorcycles would be
2x/9/x = 2/9
Answer:
B. the variability around the regression line.
Step-by-step explanation:
The standard errors represents the distance (how sparse) the observed values fall from the regression line.
Standard errors for regression are measures of the spread of variables around the average (regression line)
The standard error is dependent on the standard deviation of the observations and the reliability of the test.
When the test is perfectly reliable, the standard error is zero and when unreliable, it is equal to the standard deviation of the observations.
