Answer:
y = 3
y = 2
y = 1
y = 0
Step-by-step explanation:
Given expression;
y = (-x/3) + 2
Find:
- Value of y, if x = -3
- Value of y, if x = 0
- Value of y, if x = 3
- Value of y, if x = 6
Computation:
Value of y, if x = -3
y = (-x/3) + 2
y = (3/3) + 2
y = 3
Value of y, if x = 0
y = (-x/3) + 2
y = (-0/3) + 2
y = 2
Value of y, if x = 3
y = (-x/3) + 2
y = (-3/3) + 2
y = 1
Value of y, if x = 6
y = (-x/3) + 2
y = (-6/3) + 2
y = 0
Answer:
The standard deviation is 7.7
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
8 percent of the scores are above 89
This means that X = 89 has a pvalue of 1 - 0.08 = 0.92. So when Z = 89, Z = 1.405.
The standard deviation is 7.7
Answer:
Step-by-step explanation:
There are three times as many orange cats as black and white cats,
o = 3(b + w)
two times as many black and white cats as grey cats,
b + w = 2g
three fewer gray cats than white cats,
g = w - 3
three times as many white cats as calico cats,
w = 3L
and five white cats
w = 5
There is a problem with this.
There are 5 white cats.
There are 3 times as many white cats as calico cats.
That means there are 5/3 calico cats.
How can the number of a certain type f cats be a non-whole number?
It seems that the number of white cats must be a multiple of 3, but 5 is not.
35n=280
n=8 8 dimes and 8 quarters
A circle is 360 degrees
Divide that by 12
The angle of gah is 30 degrees
