What is the mean? If the answer is a decimal, round it to the nearest tenth.
Semmy [17]

Answer:

The mean is 52.

Step-by-step explanation:

The mean is the sum of all elements divided by the number of elements.

In this problem, we have that:

Elements

56 47 48 52 62 59 49 56 43 48

Sum

56+47+48+52+62+59+49+56+43+48 = 520

Number of Elements

10 elements

The mean is

M = \frac{520}{10} = 52

The heights of apricot trees in an orchard are approximated by a normal distribution model with a mean of 18 feet and a standard
Ulleksa [173]

Answer:

0.9544

Step-by-step explanation:

We are given that mean=18 and standard deviation=1 and we have to find P(16<X<20).

P(16<X<20)=P(z1<Z<z2)

z1=(x1-mean)/standard deviation

z1=(16-18)/1=-2

z2=(x2-mean)/standard deviation

z2=(20-18)/1=2

P(16<X<20)=P(z1<Z<z2)=P(-2<Z<2)

P(16<X<20)=P(-2<Z<0)+P(0<Z<2)

P(16<X<20)=0.4772+0.4772=0.9544

The probability that the height of a tree is between 16 and 20 feet is 95.44%

An exam consists of 10 true-or-false questions. If a student guesses at every answer, what is the probability that he or she wil
zysi [14]
This can be solved by using the binomial distribution. The probability of guessing correctly is 0.5, and the probability of making a wrong guess is also 0.5.
P(6\ correct)=10C6\times(\frac{1}{2})^{6}\times(\frac{1}{2})^{4}=\frac{210}{1024}=0.205
