Answer 1

Answer:

Answer:

D: 0.45 ; the probability that the Seahawks will not defeat the Raiders.

Step-by-step explanation:

The complement of an event A is the set of all outcomes in the sample space that are not included in the outcomes of event A.

The Complement Rule states that the sum of the probabilities of an event and its complement must equal 1, or for the event $A$ , and its complement event $\overline{A}$ always

$Pr(A)+Pr(\overline{A})=1.$

If $Pr(A)=0.55,$ then

$0.55+Pr(\overline{A})=1\n \nPr(\overline{A})=1-0.55=0.45.$

Event $A$ - the Seahawks will defeat the Raiders

Event $\overline{A}$ - the Seahawks will not defeat the Raiders

Hence, correct choice is D: 0.45 ; the probability that the Seahawks will not defeat the Raiders.

abby is putting tiles on a floor she needs 48 tiles and 8 rows each row has 6 blue tiles the rest are purple how many purple tiles will she need

Answers

48 tiles divided up into 8 rows equals 6 tiles in each row. If each row has 6 blue tiles, then all of the tiles are blue :( She does not need any purple tiles. Are you sure that you wrote your question correctly?

She will not need any purple tiles because all of her tiles, 8*6, 48, will be blue.

Calculate how much each size per gram, and circle which gives the best value for money. 250g for $2.30, 400g for &3.40, 1Kg for $5.65

Answers

To do this, we must set up ratios:
Option One:
$(2.30)/(250g) \n (0.0092)/(1g) \n 0.0092/g$
The first options costs only $0.0092/gram (a fraction of a penny)!
Option Two:
$(3.40)/(400g) \n (0.0085)/(1g) \n 0.0085/g$
The second option costs only $0.0085/gram (cheaper than option one)!
Option Three:
This requires a little more work. First, we have to convert the grams into kilograms. For every 1 kg, there is 1,000 g. Therefore, 1,000g costs $5.65. Next, we set up the ratio as usual:
$(5.65)/(1000g) \n (0.00565)/(1g) \n 0.00565/g$
The third option costs $0.00565/gram.

Therefore, option three is the cheapest!

Hope this helps!

1/8 x 4 = (1*4) / 8 = 4/8 = 1/4
1/4 x 3 = (1*3) / 4 = 3/4

1/2 x 3 = (1*3) / 2 = 3/2 = 1 1/2

Total number of tomatoes = 4 + 3 + 2 + 3 + 1 + 1 + 1 = 15 tomatoes
Total weight = 1/4 + 3/4 + 3/4 + 3/2 + 5/8 + 7/8 + 3/4

1/4 * 2/2 = 4/8
3/4 * 2/2 = 6/8
3/2 * 4/4 = 12/8

4/8 + 6/8 + 6/8 + 12/8 + 5/8 + 7/8 + 6/8 = 46/8 total weight in pounds

46/8 ÷ 15 tomatoes = 46/8 * 1/15 = 46/120 = 23/60 average weight per tomato

Maya works 16 hours per month at her part-time job earning $6.75 per hour. She earns some additional money house sitting for neighbors and friends. Maya charges $30 per day to house sit if there are no pets. If the house sitting includes pets, then she charges $40 per day. Last month, Maya spent 3 days house sitting with no pets and 5 days house sitting with pets. What is the total amount of earnings Maya had for the month? a. $270 b. $290 c. $378 d. $398

Answers

From the informations provided within the question, we know that:
Maya works for 16 hours at the rate of $6.75 per hour.
Maya worked for 3 days in a house sitting without pets for $30 per hour.
Maya also worked for 5 days in a house sitting with pets for $40 per hour.
Now we have to find out the total income maya made during the month.
Firstly
Income from per time job for the month = (16 * 6.75) dollars
      = 108 dollars
Income from house sitting without pets for the month = ( 3 * 30) dollars
   = 90 dollars
Income from house sitting with pets for the month = ( 5 * 40) dollars
   = 200 dollars
So the total income made by Maya in the month = (108 + 90 + 200) dollars
   = 398 dollars
So the correct option for this question is option "d".
