Answer:

Sample size

Step-by-step explanation:

Central Limit Theorem states that population with mean and standard deviation and if the sample size is large then the distribution of sample mean will be will be normally distributed. The central limit theorem holds assumptions that the factors to be considered when assessing central limit theorem is sample size.

zaharov [31]

Answer:

11° is the measure of the exterior angles

Step-by-step explanation:

Theorem: Alternate exterior angles are congruent when two parallel lines cut by a transversal.

First we solve for x using the theorem

6x + 5 = 7x + 4

x = 1

Substitute x = 1 into 6x + 5

6(1) + 5 = 6 + 5 = 11°

What are the solutions of the system?

svetlana [45]

Answer:

Option C. No solution is the right answer.

Step-by-step explanation:

Here the given equations are y = x²+2x+3 -----(1)

and y = 4x-2 -------(2)

Now we substitute the value of y from equation 2 into 1.

x²+2x+3 = 4x-2

x²+2x+3-2x = 4x-2-2x

x²+3 = 2x-2

x²+3-2x = 2x-2x-2

x²-2x+3 = -2

x²-2x+5 = 0

Then value of $x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}$

$=\frac{+2\pm \sqrt{4-4\times 1\times 5}}{2}$

$=\frac{2\pm \sqrt{4-20}}{2}$

Since in this solution √(-20) is not defined. Therefore there is no solution.

Solve the quadratic. x^2+8x+3=0

Reil [10]

Factor
find wht 2 numbers add to 8 and multiply to 3
none do

use quadratic formula which can be used when
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^{2}}-4ac }{2a}$

a=1
b=8
c=3

x= $\frac{-8+/- \sqrt{8^{2}-4(1)(3)} }{2(1)}$
x= $\frac{ -8+/- \sqrt{64-12} }{2}$
x= $\frac{ -8+/- \sqrt{52} }{2}$
x= $\frac{ -8+/- 2 \sqrt{13} }{2}$
x= $-4+/- \sqrt{13}$

x= $-4+ \sqrt{13}$ or x= $-4- \sqrt{13}$
aprox x=-7.60555 or x=-0.394449
