If 6/? makes of 12/100, we need to divid 100 by two to figure out the denominator of six. This is because to go from 12 to six (the numerators), you divide by two, so you do it for the denominator as well. This would give 6/50, which means there are 6 red marbles out of 50 marbles in the collection.

The sum of 4 consecutive integers is 182. W hat is the sum of the middle two numbers?
Kamila [148]

Answer:

91

Step-by-step explanation:

Let

x = first number

x+1 = second number

x+2 = third number

x+3 = fourth number

Total = 182

x + x + 1 + x + 2 + x + 3 = 182

4x + 6 = 182

Subtract 6 from both sides

4x + 6 - 6 = 182 - 6

4x = 176

Divide both sides by 4

x = 176 / 4

= 44

x = 44

x = 44

x+1 = 44 + 1 = 45

x+2 = 44 + 2 = 46

x+3 = 44 + 3 = 47

Sum of the two middle numbers = 45 + 46

= 91

This lesson asked you to investigate what it means for data to fall within 1, 2, and 3 standard deviations from the mean in a va
s2008m [1.1K]

Answer:

The data in statistics is generally supposed to deviate or vary from the mean. Standard deviations of 1, 2, and 3 are commonly used to calculate variability according to the empirical norm. In a normal distribution, we estimate 68 percent, 95 percent, and 98 percent of the data to be within 1, 2, and 3 standard deviations of the mean, respectively. This implies that the given percentage of data will lie within an interval of less than or greater than the standard deviation. If the values within a given standard deviation from the mean are standardized, the z value will always be equal to or less than the given standard deviation.

We should look at a program that aims to help people get out of poverty by using the standard deviation principle. The aim of the program is to provide free seeds to poor people who have been suffering from low yields due to the use of local seeds. If we use the definition of one standard deviation of the mean, or 2 and 3, we will favor the majority of people, but we will leave the poorest people in society behind.
