Answer:
16 and 73
Step-by-step explanation:
The question is missing some data. The distribution of the number of students is represented on the following stem-and-leaf plot:
The numbers in the first column represent the tens and the numbers on the second column represent the units. The number of students over the past 13 years were:
16, 19, 24, 24, 25, 33, 34, 37, 40, 42, 46, 49, 73.
Therefore, the smallest and largest number of students were 16 and 73.
I found the image that should have accompanied this problem.
Given:
equilateral triangle with sides that measures 7cm.
hexagonal shape meaning 6 sides or 6 equilateral triangles used.
Area of an equilateral triangle = √3/4 * a²
A = √3 /4 * (7cm)²
A = 1.73/4 * 49cm²
A = 21.20 cm²
21.20 cm² * 6 tiles = 127.20 cm² ARea of the hexagon.
Answer:
50.24
Step-by-step explanation:
1/4x3.14xr^2
r=16 because of the length
90/360= 1/4
so
1/4x3.14x16^2/4
=50.24
4 is our denominator because of the denominator on the fraction
Answer:
The answer to your question is 20 ft squared
Step-by-step explanation: when you hear the word "side length", it means that whatever the side length is on one side, then this means that the other side lengths are gonna be the same side length as well. For example, we already know that a square garden has a side length of 5 ft. So, since we are trying to the find the area of the square garden, you can either multiply the side length of the square garden by 4, or you can add the side length of the square garden 4 times, which will look like this:
5ft*4ft=20ft2
or 5ft+5ft+5ft+5ft= 20ft2
Answer:
A ∩ Bc
Step-by-step explanation:
Home constructed of brick:
Event A
Home is less than or equal to 30 years old.
Event B is: {The home is more than 30 years old}
So the event home is less than or equal to 30 years old is the negation(complement) of B. So Bc.
And:
And means intersection.
We have the intersection of events A and the complement of event B, which is represented by:
A ∩ Bc
