Answer:
A value two standards deviation from the mean is more likely to occur than a value three standard deviations from the mean.
Step-by-step explanation:
Standard deviation is a quantitative measure of the variability of traits of the subjects in a given population. These traits can range from age, height, weight e.t.c. This deviation is brought about by extreme or abnormal conditions, which is the reason why two deviations is more likely to occur than three deviations.
Moreover, going by the provisions of the empirical rule, If data comes from a population that is approximately symmetrical;
95% of the data will fall within two standard deviations.
99.7% will fall within three standard deviations
Find the attachment below.
Nevertheless, in a symmetrical distribution most of the data values fall around the mean. Two standard deviations is closer to the mean than 3 standard deviations hence more likely to occur.
Answer:
A. 5s+2
B. 8s+8
C. 75
D. 27
Step-by-step explanation:
Is difficult to read the exact expressions. If a mistake is present then fix the number and use the same method.
A. The perimeter of the square is all 4 equal sides added together. The length of a side is 
. Since there are four sides then:
Adding 1/4+1/4+1/4+1/4=1. This applies here leaving 5s+2 as the answer.
B. The perimeter of the rectangle is all four sides added together. A rectangle has two pairs of equal side so P = 2l+2w.
C. If s=5 then the sum of the two perimeters is:
5s+2+8s+8
5(5)+2+8(5)+8
25+2+40+8
75
D. Subtract the two perimeters by computing s=7:
8s+8 -(5s+2)
8s+8-5s-2
8(7)+8-5(7)-2
56+8-35-2
64-35-2
29-2
27

Answer:</h2>
First we must find the opposite-reciprocal of the original slope.
current slope: 
new slope: 
Using the new slope and the given point, we will plug them into slope-intercept form and solve for b, the y-intercept.
The y-intercept is 
.
Now, we can write the formula for the new line.
Slope-intercept form: 
Point-slope form: 
Answer:
20%
Step-by-step explanation:
150-120 is 30
30 is 1/5 of 150
1/5 is .2, which is 20%
Hope that helps~
