Answer:
<em>2.5%</em><em> of the snakes are longer than 16.6 in</em>
Step-by-step explanation:
The Z score is,
here,
X = raw score = 16.6
μ = mean = 15
σ = standard deviation = 0.8
So,
Z-score is the measurement of how many standard deviation away the data is from the mean. Hence, the value 16.6 is 2 standard deviations right to the mean.
Approximately 95% of the data falls within two standard deviations of the mean. (between the mean-2 times the standard deviation, and the mean+2 times the standard deviation)
So the 5% of data are left in the remaining space. As we have to find the amount of snakes which are longer than 16.6 in i.e we have to find the area to the right of 16.6.
The remaining 5% of amount is divided in two equal parts.
Therefore, of the snakes are longer than 16.6 in
Answer:
Check the attached graph for correct match.
Step-by-step explanation:
Graph of the given choices are not given but we can still solve this problem.
Given equation is 15x-12y=60.
Which is linear equation so we need at least two points to get the graph.
We are free to select any random number of x then plug that into given equation to find other variable.
Let's use x=0
15x-12y=60
15*0-12y=60
0-12y=60
-12y=60
divide both sides by -12
y=-5
Hence point is (0,-5)
Similarly plug y=0
15x-12y=60
15x-12*0=60
15x-0=60
15x=60
divide both sides by 15
x=4
Hence point is (4,0)
Now graph both points then join them by a straight line.
Any graph given in the choices which match with attached graph will be the answer.
Check the attached graph for correct match.
