Answer:

x=2, x=a

Step-by-step explanation:

(x -2) (x-a) = 0

(x-2)(x-a) = 0

x-2=0

x-2+2=0+2

x=2

x-a=0

x-a+a=0+a

x=a

Random samples of size 64 are taken from an infinite population whose mean and standard deviation are 24 and 6.4, respectively.
umka2103 [35]

Answer:

Mean 24, standard error 0.8

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, the sample means with size n of at least 30 can be approximated to a normal distribution with mean \mu and standard deviation, also called standard error s = \frac{\sigma}{\sqrt{n}}

In this problem, we have that:

\mu = 24, \sigma = 6.4, n = 64

What are the mean and the standard error of the sample mean?

By the Central Limit Theorem, mean 24 and standard error s = \frac{6.4}{\sqrt{64}} = 0.8

The area (in square centimeters) of a square coaster can be represented by d^2+8d+16 .
Katarina [22]

ANSWER

a. d+4

b. 4d+16

EXPLANATION

The area of the square coaster is represented by:

{d}^{2}  + 8d + 16

We split the middle term to obtain,

{d}^{2}  + 4d + 4d + 16

We factor by grouping to get,

d(d + 4) + 4(d + 4)

(d + 4)(d + 4) =  {(d + 4)}^{2}

Since area of a square is l² , it means the side length of the square is

l = d + 4

b) The perimeter of a square is given by

P=4l

We substitute the length in terms of d, to obtain;

P=4(d + 4)

Or

P=4d + 16
