The difference of 10 and the square of a number is less than 18

Dimas [21]

Answer:

x^2 - 10 < 18

Step-by-step explanation:

"the difference of 10" means something is being subtracted by 10

"square of a number" means that an unknown number is squared (to the second power)

"less than 18" means the difference of the two numbers is less than 18

12. Convierte estas fracciones impropias en números mixtos:

Vinvika [58]

¡Hola! Voy a hacer el mismo proceso para cada uno.

Primero, restaré el denominador del numerador hasta que sea una fracción propia. También simplificaré si es necesario.

Luego, "volveré a sumar los números enteros al número" como un número mixto.

A. 15/7

$\displaystyle \frac{15-7-7}{7} =\frac{1}{7}$

$\displaystyle \frac{1}{7}+1+1=$

$\displaystyle 2\frac{1}{7}$

B. 16/6

$\displaystyle \frac{16-6-6}{6} =\frac{4}{6}=\frac{2}{3}$

$\displaystyle \frac{2}{3}+1+1=$

$\displaystyle 2\frac{2}{3}$

C. 12/5

$\displaystyle \frac{12-5-5}{5} =\frac{2}{5}$

$\displaystyle \frac{2}{5}+1+1=$

$\displaystyle 2\frac{2}{5}$

D. 48/7

$\displaystyle \frac{48-7-7-7-7-7-7}{7} =\frac{6}{7}$

$\displaystyle \frac{6}{7}+1+1+1+1+1+1=$

$\displaystyle 6\frac{6}{7}$

In 2014, the percentage of the U.S population who was foreign-born was 13.1. Choose 60 U.S residents at random. Find the mean, v

makkiz [27]

Answer:

Hence Mean ,variance ,standard deviation who are foreign born are as

8, 6.83 ,2.613 respectively

Step-by-step explanation:

Given:

probability of success for foreign-born is 13.1 % p=0.131

probability of failure= q=1-0.131=0.869

n=60

To Find:

Mean ,variance and standard deviation

Solution:

We have here binomial distribution as probability for success (p)and number of trails are given (n).

So we know that formula for mean ,variance and standard deviation of binomial distribution are as follows ,

p=0.131

q=0.869

n=60

So Mean=μ= n*p

=60*0.131

=7.86

Hence mean will be 7.86 which approximately 8 persons.

Now for Variance=n*p*q

=60*0.131*0.869

=6.830

So variance will be 6.83

And for Standard deviation=Sqrt(variance)=Sqrt(n*p*q)

=Sqrt(6.83)

=2.613

Hence Mean ,variance ,standard deviation who are foreign born are as

8, 6.83 ,2.613 respectively.
