The necklace chain costs $15, so subtract 15 from the total cost of $28.75.
28.75 - 15 = $13.75
Then, to find the amount of beads you divide the remaining amount by the cost of the beads.
13.75 ÷ 2.75 = 5
Therefore, you bought 5 beads.
Answer:
David gets 20 sweets.
Step-by-step explanation:
If you want the ratio, 2:2:1, Krustika gets 20 more than mark, you will need to have double what mark got.
So, the only number I can think of that is half, but also 20 more than the "1" ratio, is 20; as 20 is half of 40, however, 40 is also 20 more than the "1" ratio.
Answer:
Using the calculator angle whose cos is 0.9511 is 18 degrees
Sine of the complementary angle = 0.9511 also
Step-by-step explanation:
The sine of the complementary angle( which is 90-18 = 72 degrees) is same value 0.9511
Answer:
The assumption of homoscedasticity is that "<u>the variability of Y doesn't change over the X scores</u>."
Step-by-step explanation:
The assumptions of linear regression are:
- Linear relationship
- Multivariate normality
- Almost 0 mulitcollinearity
- 0 Autocorrelation
- Homoscedasticity
The assumption of homoscedasticity implies that the variance of the dependent variable <em>Y</em>, across the regression line does not changes for all values of the predictor variable <em>X</em>.
Thus, the complete statement is:
The assumption of homoscedasticity is that "<u>the variability of Y doesn't change over the X scores</u>."
