8 0

Bear in mind that words like "are" or "is" is replaced by an equal "=" sign in the equation.
more than or increased by denotes addition
twice the number denotes two times the number
times, simply means multiply.

Let x be the unknown number in the equations.

12 birds are 3 more than twice the number of birds Rhonda saw yesterday.

12 = 2x + 3

Negative 6 times the sum of a number and 4 is 2

-6(x+4) = 2

Four time a number increased by 3 is -89

4x + 3 = -89

Hope this helps!

Twenty-five randomly selected students were asked the number of movies they watched the previous week. The results are as follow

guajiro [1.7K]

Answer:

a) x = 1.52

b) s = 1.16

Step-by-step explanation:

We have that:

5 students watched 0 movies.

9 students watched 1 movie.

5 students watched 2 movies.

5 students watched 3 movies.

1 student watched 4 movies.

(a) Find the sample mean x.

Sum divided by the number of students. So

$x = \frac{5*0 + 9*1 + 5*2 + 5*3 + 1*4}{5 + 9 + 5 + 5 + 1} = \frac{38}{25} = 1.52$

(b) Find the approximate sample standard deviation, s.

Standard deviation of the sample.

Square root of the sum of the squares of the values subtracted from the mean, divided by the sample size subtracted by 1. So

$s = \sqrt{\frac{5*(0-1.52)^2 + 9*(1-1.52)^2 + 5*(2-1.52)^2 + 5*(3-1.52)^2 + 1*(4-1.52)^2}{24}} = \sqrt{\frac{32.24}{24}} = 1.16$

A total of about 230 million turkeys were raised in the U.S. last year. Were more than one-quarter of them raised in Minesota if

pochemuha

No, 17.39% were raised in Minnesota.

You can find this by dividing 40,000,000 by 230,000,000 and then converting to a percent by multiplying by 100.

40,000,000/230,000,000=.1739
.1739 x 100= 17.39%
