Answer:
D.
The points do not follow the line of fit, and the line is increasing.
Step-by-step explanation:
Given that correlation coefficient between two variables x and y is 0.30
This implies that there is a positive relationship in other words, when x increases y increases.
Since r is close to 0 than to 1, there is a weak correlation only.
So all points will not lie very close to the line.
There will be positive slope and hence line would be increasing.
Out of the four options correct option would be that which says all points do not follow line of fit and line increases
So option d is right
D.
The points do not follow the line of fit, and the line is increasing.
Answer:
More than 8 seconds
Step-by-step explanation:
Xandler
- Has water = 15.4 oz
- Decrease rate = 0.5 oz/sec
Leon
- Has water = 5.4 oz
- Addition rate = 0.75 oz/sec
Time = x
<u>Inequality for the required condition is:</u>
- 15.4 - 0.5x < 5.4 + 0.75x
- 10 < 1.25x
- x > 10/1.25
- x > 8 seconds
1.5 kg of rice ... 9.60
1 kg of rice ... x = ?
If you would like to know the price of 1 kg of rice, you can calculate this using the following steps:
1.5 * x = 9.60 * 1
1.5 * x = 9.6 /1.5
x = 9.6 / 1.5
x = 6.40
The correct result is 6.40.

Answer:
A dependent variable is a factor that changes because of procedures conducted on the independent variable
Step-by-step explanation:
Using a cause and effect analogy, the independent variable is the causal variable. The independent variable or variables are the variables on which what is being measured, has no effect, and it is the variable the investigator manipulates to find the effect on the dependent variable.
The dependent variable are the variables that shows he effect of the changes made and manipulations to the independent variable. The dependent variable is therefore, the effect variable
Therefore, the correct option is ' A dependent variable is a factor that changes because of procedures conducted on the independent variable'
