Mathematics
1 answer:
noname [10]3 years ago
5 0

Answer:

T = total #

T = 5 (to the aunt) + 1/2 (T - 5) (to his friends) + 1 (to his sister) + 4 (left)

T = 5 + 1/2 (T - 5) + 1 + 4

T = 10 + 1/2 (T - 5)

2T = 20 + (T - 5)

2T = 20 + T - 5

2T = 15 + T

T = 15

The data shows the speed, in miles per hour, of motorists on a stretch of road.
melomori [17]

Answer:

i. 18 miles per hour is an outlier

ii. the outlier decreases the mean speed

Step-by-step explanation:

An outlier in a given data is one of the values that is far greater or lesser compared to others. It affect the mean and standard deviation of a given data significantly.

From the given data, 18 is far too small compared to other values. This is certainly an outlier. This would affect the mean speed by decreasing the value.

An interquartile range is a measure of differences among data by dividing a set of given data into quartile. Increasing the value of the outlier would increase the interquartile range.

A silo is a composite of a cylindrical tower with a cone for a roof. What is the volume of the silo if the radius of the base is
kirza4 [7]

Answer:

The answer is b. 343,480.8ft

Step-by-step explanation:

I thought it was c at first because I forgot to add the volume of the cone.

The equation for the volume of a cylinder is V=π×r²×h

The solution would look like V=π40²×65=326725.8

The equation for the volume of a cone is V=1/3πr²×h

The solution would look like V=1/3π×40²×10=16755

Adding the two volumes would equal 326725.8±16755= 343480.8

A.Draw parallel lines AB and CD.
ddd [48]

Answer:

Lines stay parallel or overlap

Step-by-step explanation:

AB and CD are parallel lines

Rotation around a point 90 degrees clockwise will make these lines perpendicular to their initial position but AB and CD will still be parallel to each other

They will overlap if the distance between them and point E is equal

Their initial slope is same and equal to m

Their final slope will be -1/m as a result of 90 degrees rotation
