We are given with a triangle and three medians. The intersection of the two medians is also given which is (4,5). What is asked is the intersection between another pair of medians. Since the medians of a triangle intersect at the centroid of a triangle, the intersection is also

Answer:
The standard deviation of the data set is 
.
Step-by-step explanation:
The Standard Deviation is a measure of how spread out numbers are. Its symbol is σ (the greek letter sigma)
To find the standard deviation of the following data set
we use the following formula
Step 1: Find the mean 
.
The mean of a data set is the sum of the terms divided by the total number of terms. Using math notation we have:
Step 2: Create the below table.
Step 3: Find the sum of numbers in the last column to get.
Step 4: Calculate σ using the above formula.
The square root of 41 or
is 6.40 rounded to the nearest hundredth.
6.40
Answer:
90%
Step-by-step explanation:
Let's call the percentage of students that read Time magazine by P(T), and the percentage of students that read U.S News and World Report by P(U). So, we have that:
P(T) = 0.63
P(U) = 0.51
P(T and U) = 0.24
To find the percentage of students that read either the Time magazine or the U.S.News and World Report magazine (that is, P(T or U)), we can use this formula:
P(T or U) = P(T) + P(U) - P(T and U)
So, we have that:
P(T or U) = 0.63 + 0.51 - 0.24 = 0.90
So the probability is 90%
Given:
discount of 25%
Hasan's equation: d - 0.25d
Bella's equation: 0.75d
d represents the original price.
0.25d represents the discount.
0.75d represents the discounted price.
Example: 1,000 is the price. d = 1,000
0.25d = 0.25(1000) = 250 this is the discount
0.75d = 0.75(1000) = 750 this is the discounted price
Hassan: d - 0.25d = 1000 - 250 = 750
Bella: 0.75d = 0.75(1000) = 750
