Answer:
B. The histogram appears to roughly approximate a normal distribution. The frequencies generally increase to a maximum and then decrease, and the histogram is symmetric.
Step-by-step explanation:
The Graph of Normal Distribution is like a bell-shaped. Here the value of y is less for the lower value of x and then the value of y is increased for a larger value of x, but after some time value of y is again getting decrease as the value of x increases. For the Histogram to appear to a normal distribution, the graph of histogram must have the same nature. Thus option B is only the correct option.
The histogram is made up of columns bar with no gaps between bars with different labels of numeric data of different heights shows the size of the group of different labels.
Answer:
-2+11x
Step-by-step explanation:
Combine like terms
(-5+3)+(x+10x)
-5+3 = -2
x+10x = 11x
-2+11x
Answer:
4C2 * 6C2 * 5C2
Step-by-step explanation:
White balls = 4
Yellow balls = 6
Red balls = 5
In other to select a total of 6 balls, of which there must be 2 balls each of color white, yellow and red :
That means :
2 red balls from 5 red balls = 5C2
2 balls for 6 yellow balls = 6C2
2 balls from 4 white balls = 4C2
To obtain the number of possible combinations, take the product of the three combinations :
4C2 * 6C2 * 5C2
