hoa [83]

Answer:

<u>A. Mean = 402.5</u>

<u>B. Variance = 77,556.25</u>

<u>C. Standard Deviation = 278.49</u>

Step-by-step explanation:

Let's calculate the mean, variance and standard deviation of the set of numbers given:

A. Mean = (45 + 340 + 400 + 825)/4 = 1,610/4 =<u> 402.5</u>

B. Variance [(45 - 402.5)² + (340 - 402.5)² + (400 - 402.5)² + (825 - 402.5)²]/4 = [(127,806.25 + 3,906.25 +6.25 + 178,506.25/4 =<u> </u><u>77,556.25</u>

C. Standard Deviation = √Variance = √77,556.25 =<u> 278.49</u>

Answer:

a) A n (B' n C') = {3, 9}.

b) (AUB) n (BUC) = {2,4,5,6,7,8}

Step-by-step explanation:

a) Rewriting C ; C = {4,5,6,7,8}

B' = {3,5,7,9} and C' = {2, 3, 9}

so (B' n C') = {3, 9}

and A n (B' n C') = {3, 9}.

b) {A U B} = { 2,3,4,5,6,7,8,9} and {B U C} = {2,4,5,6,7,8}

so (AUB) n (BUC) = {2,4,5,6,7,8}

AfilCa [17]

Answer:Tara will need to buy more 8 2/3 pint of green paint.

Step-by-step explanation:

Total amount of green paint Tara has =24 pints

Amount used to to paint a landscape =1/4 x 24= 6

Amount used To painting a clover.= 5/8 x 24= 15

Amount of paint remaining = Total paint - Amount used up in painting landscape and clover

= 24 - ( 15+ 6)

24-21

=3 pints left

Since she needs 11 2/3 pints of green paints , she will need

11 2/3 - 3 = 8 2/3 .

Therefore she will need to buy more 8 2/3 pint of green paint.
