Answer:
13.3
Step-by-step explanation:
f² = e² + g² - 2(e)(g)cos(F)
f² = 9² + 18² - 2(9)(18)cos(45)
f² = 175.8974029
f = 13.262631982
one bag contains x pencils
5 bags contain 5x pencils
after adding 3 pencils to each bag
total no of pencils = 5(x+3)
According to question,
5(x+3)=45
x+3=45/5
x+3=9
x=6
one bag contained 6 pencils before adding
Answer:
The following is NOT TRUE about the normal distribution, that is, d.) The curve is right-skewed(that is, skewed to the right).
Step-by-step explanation:
In a normal distribution the properties of which are given as follows:
i) all the central tendency measures, that is, the mean, the median and the mode are equal.
ii) The area under the bell curve is equal to one.
iii.) The bell curve is symmetric about the center, or mean.
iv.) The bell curve does not touch the x - axis.
Therefore only the following is NOT TRUE about the normal distribution, that is, d.) The curve is right-skewed (that is, skewed to the right).
