Answer
the lengths of the chords are 12 cm and 6 cm
Answer:
68
Step-by-step explanation:
We let the random variable X denote the height of students of the college. Therefore, X is normally distributed with a mean of 175 cm and a standard deviation of 5 centimeters.
We are required to determine the percent of students who are between 170 centimeters and 180 centimeters in height.
This can be expressed as;
P(170<X<180)
This can be evaluated in Stat-Crunch using the following steps;
In stat crunch, click Stat then Calculators and select Normal
In the pop-up window that appears click Between
Input the value of the mean as 175 and that of the standard deviation as 5
Then input the values 170 and 180
click compute
Stat-Crunch returns a probability of approximately 68%
Answer:
y= 4x+1
Step-by-step explanation:
y = mx + b
The b is the y-intercept, so to find it you just need to find where the line is on the y-axis when x is zero
The slope is just rise over run (y2-y1/x2-x1), so the graph in the picture shows us that the line goes up 4 to go over 1. Therefore the slope is 4/1 which is equal to 4.
Answer:
The answer is 2.89 in 2dp
3 cube is 27
27 minus 6.8 is 20. 2
20. 2 decide by 7 is 2.89
Yes. The ratio is 2/6 which is 1/3 and 3/9 which is also one 1/3. The ratios are the same.
