Answer:
Solution:
Mouse ran 360 cm straight course race in 9 seconds.
We need to find the rate or speed of mouse
We know the speed formula is distance covered by given time.
Where,
Distance = 360 cm
Time = 9 seconds
speed
Speed=40 cm/s
Mouse ran with speed 40 cm/s
Total number of pastries = 54 + 31 + 10 = 95
Number of croissants = 10
Probability of picking a croissant = 10/95
On simplifying, we get, <u>2/19</u>
Option A will be the correct answer
Solution: Which statement about the scatter plot is true?
The correct answer is option A. As the number of weeks in class increases, the number of keyboarding mistakes decreases.
Explanation: From the scatter plot, we clearly see there exists a negative linear relationship between the number of weeks in class and the number of mistakes. And we know that if there exists a negative linear relationship between the two variables, then the values of two variables move in opposite direction. If the values of one variable goes up, the values of other variable go down. From the given scatter plot, we clearly see the number of mistakes goes down as the number of weeks in class increases. Therefore, the option A is correct
1 minute of P.E. usually burns 11 Kcals.
