Answer:

a.)

Step-by-step explanation:

(\sqrt{12}+6)(-\sqrt{8}-\sqrt{2})

Find the simplest radical form for \sqrt{12}:

Find two numbers that multiply to 12, one of which is a perfect square:

\sqrt{12}=\sqrt{3*4}

Separate:

\sqrt{3}\sqrt{4}

Simplify by finding the square root:

\sqrt{3}*2=2\sqrt{3}

Insert the simplified version:

(2\sqrt{3}+6)(-\sqrt{8}-\sqrt{2})

Find the simplest radical form of \sqrt{8}:

Find two numbers that multiply to 8, one of which is a perfect square:

\sqrt{8}=\sqrt{4*2}

Separate:

\sqrt{4} \sqrt{2}

Simplify by finding the square root:

2\sqrt{2}

Insert the simplified version:

(2\sqrt{3}+6)(- 2\sqrt{2}-\sqrt{2})

Sorry this is taking forever to type, here

The class sizes of the introductory psychology courses at a college are shown below 121,134,106,93,149,130,119,128 the college a
frozen [14]
Center : Mean  Before the introduction of the new course, center = average(121,134,106,93,149,130,119,128) = 122.5  After the introduction of the new course, center =  average(121,134,106,93,149,130,119,128,45) = 113.9  The center has moved to the left (if plotted in a graph) because of the low intake for the new course.  Spread before introduction of the new course :  Arrange the numbers in ascending order:  (93, 106,119, 121), (128, 130,134, 149) Q1=median(93,106,119,121) = 112.5 Q3=median(128,130,134,149) = 132  Spread = Interquartile range = Q3-Q1 = 19.5  After addition of the new course,

 (45,93, 106,119,) 121, (128, 130,134, 149)
 Q1=median(45,93,106,119)=99.5
 Q3=median (128, 130,134, 149)= 132
 Spread = Interquartile range = 132-99.5 =32.5 
 We see that the spread has increased after the addition of the new course.

Answer:

Just Between Friends

The percentage of consignors who receive a check for more than $370 is:

= 16%.

Step-by-step explanation:

Mean of consignor check, μ = $480

Standard deviation, σ = $110

Value of check received, x > $370

Solution: find the z-score to determine the percentage of consignors who receive a check for more than $370:

z = (x-μ)/σ

z= ($370 - $480)/$110

z = -$110/$110

z = -1.00

Percentage of consignors who receive a check for more than $370

= 0.15866

= 0.16

= 16%
