Answer:
The ratio is 
Step-by-step explanation:
The question in English is
In a group of high school third graders, 38 are right-handed and 6 are left-handed. find the ratio of right-handed to left-handed
Let
x -----> number of students that are right-handed
y -----> number of students that are left-handed
we know that
To find out the ratio of right-handed to left-handed, divide the number of students that are right-handed by the number of students that are left-handed
so
we have
substitute
Simplify
Answer: 180
Hope it helps
Step by step explanation:
1000*.18=180
Answer:
Step-by-step explanation:
Given
Three and one-half yards of fabric i.e. 
yards
and five and one-half yards of fabric is 
yards
Difference between five and one-half yards and Three and one-half yards is
=2 yards which is positive
Thus it clear that 
If two planes are perpendicular, they intersect. if two planes are parallel, they will never touch. hope this helps
Answer:
1. A: 0.25; B: 0.03; C: 1.41; D: -0.28
2. A: 0.39; B: 0.06; C: 40.30; D: 21.81
Step-by-step explanation:
For CDF lookups, we used the Excel NORMDIST(x, mean, stdev, TRUE) function. For inverse CDF lookups, we used the NORMINV(x, mean, stdev) function.
Each of these functions works with the area under the curve from -∞ to x, so for cases where we're interested in the upper tail, we subtract the probability from 1, or subtract the x value from twice the mean.
For question 1, we computed the Z values in each case. The NORMDIST function works directly with x, mean, and standard deviation, so does not need the z value.
