Answer:
160 the total area
Step-by-step explanation:
10×10=100=area of square
5×12=60=area of triangle
Answer: cumulative frequency
Step-by-step explanation:
- A frequency is the number of times a data value occurs.
- A relative frequency is the fraction or proportion of times an answer occurs.
- The cumulative frequency analysis is the analysis of the frequency of occurrence of values of a phenomenon less than a reference value.
In a data set, the cumulative frequency for a value x is the total number of scores that are less than or equal to x.
Hence, cumulative frequency represents the number of times all outcomes less than a given outcome occur.
Answer:
x = 4
y = 8
Step-by-step explanation:
this is a 30-60-90 triangle and the sides have a constant ratio
the side across from the 30°∡ is 1
the side across from the 60°∡ is √3
the side across from the 90°∡ is 2
In this problem we can find 'x' by setting up this proportion:
x/12 = /1
cross-multiply:
x = 12
x = 12/
since we don't like to leave radicals in the denominator, we can multiply both numerator and denominator by to get:
12 ÷ · (· = , which equals 3)
so we have 12/3, which is 4
The 'y' value will be twice the 30° side, so 8
The factorization of A is y = (x - 8)(x + 7).
The factorization of B is y = (x + 1)(x - 4)(x - 5)
In order to find these, you must first find where each graph crosses the x-axis. In the first problem it does so at 8 and -7. In order to find the correct parenthesis for those, you need to write it out as a statement and then solve for 0.
x = 8 ---> subtract 8 from both sides
x - 8 = 0
This means we use (x - 8) in our factorization.
You then need to repeat the process until you have all the pieces. In the second problem, there will be 3 instead of 2 since it crosses the axis 3 times.
