Answer:
502 Square Meters
Step-by-step explanation:
Surface Area is the sum of the areas of all the surfaces. There are 5 surfaces in total, so we find each surface area and find total Surface Area.
Shown Below:
Bottom Surface is a rectangle, so area is length * width = 10 * 16 = 160
Back Surface is a rectangle, so area is 6 * 16 = 96
Top (front) surface is a rectangle so area is 11.6 * 16 = 185.6
Left and right sides are 2 triangles, so are would be 0.5(base * height) for each. So,
Left triangle = 0.5 * 10 * 6 = 30
Right triangle = 30
Sum of all the surfaces = 160 + 96 + 185.6 + 30 + 30 = 501.6
Rounded to nearest whole number, that is 502
The surface area = 502 m^2
Answer: C) There is a probability that the outcome is within 1 standard deviation of the mean.
Step-by-step explanation:
The Standard Deviation Rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean. According to the rule,
68% of data falls within the first standard deviation from the mean.
95% fall within two standard deviations.
99.7% fall within three standard deviations
Therefore, the correct answer is
C) There is a probability that the outcome is within 1 standard deviation of the mean.
Answer:
10
Step-by-step explanation:
Here, we want to get the biggest number of spoon or forks that the bucket will have
What we have to do here is to simply find the greatest common factor of 100 and 80
Finding the greatest common factor of both will
give the biggest number of spoon or forks that the bucket will have
Mathematically, the greatest common factor of 80 and 100 is 10
This is for the first one 85.714286%
This is for the second one
olution for 21 is what percent of 300
100%/x%=300/21
(100/x)*x=(300/21)*x - we multiply both sides of the equation by x
100=14.2857142857*x - we divide both sides of the equation by (14.2857142857) to get x
100/14.2857142857=x
7=x
x=7
now we have:
21 is 7% of 300
