Answer:1/8
Step-by-step explanation:
If we divide both the top and the bottom by 5 since we know that 125 is a multiple of 5, we get 25/200. Divide both by 5 again to get 5/40 we then simplify to get 1/8.
Answer:
There are 604,800 possible permutations.
Step-by-step explanation:
The order in which the digits are chosen is important, which means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this question:
7 digits from a set of 10(10 digits to 0-9). So
There are 604,800 possible permutations.
Answer: 0.0775
Step-by-step explanation:
Given : Mean :
Standard deviation :
Sample size :
Since its normal distribution , then the formula to calculate the z-score is given by :-
For x= 28.2 hours
For x= 30 hours
The P- value =
Hence, the probabiliy that the average time spent stydying for the sampe was between 28.2 and 30 hours = 0.0775
it represents the amount of wine cucumber and one apple
Answer:
Step-by-step explanation:
In order to identify the equation of line from the given graph, we need to find the slope and the y-intercept.
Slope of a line is the ratio of rise to run or change in over change in .
The y-intercept is a point on the line for which the value is 0. In other words, it is on the y-axis.
Here, from the graph,
y-intercept is at point (0,4). So, y-intercept is the value which is,.
Also, slope is given as,
Therefore, the equation of the line is:
