Multiply: (4x – 7)(2x – 9)

Answers

Hello there!


Let's use foil.

First: 4x * 2x = 8x^2

Outside: 4x * -9 = -36x

Inside: -7 * 2x = -14x

Last: -7 * -9 = 63


Now, let's combine these.

8x^2 - 36x - 14x + 63

Finally, we can simplify this

8x - 50x + 63

Three families each have three sons and no daughters. Assuming boy and girl babies are equally likely, what is the probability of this event?

Answers


I don't think it matters how many families are involved. 
You're talking nine live births, and the probability of a
male birth each time is 50% .

So the probability of nine males in nine births is

                 (1/2)^9  =  1/512  =  about 0.195 percent  (rounded)


three families with three children all boys 
parents-2
children-3
total-5 times 3= 15
then boys-3 times three=9

Answer: 9/12 
Percentage:75%

PLS HELP ME OUT REWARD GUARANTEE!!!!!!!!!!!!!The fat content for seven different sandwiches at a restaurant is 42, 61, 13, 9, 12, 42, and 62. Find the mean, median and mode of the fat contents.

Answers

Mean: subtract the smallest number from the biggest number...62-9=?Median: the middle number, order the numbers from smallest to biggest....Mode: the number that is repeated the most...This should help you. I do not want to give you the answers. I want you to do them yourself with the instructions I gave you and then come back and post them when you are done so I may check them. Okay?
Mean: \bar{x} = (x_(1) + x_(2) + x_(3) + x_(4) + x_(5) + x_(6) + x_(7))/(n)
           \bar{x} = (42 + 61 + 13 + 9 + 12 + 42 + 62)/(7)
           \bar{x} = (241)/(7)
           \bar{x} = 34(3)/(7)

Median: 9, 12, 13, 42, 42, 61, 62
                              42

Mode: 42

The model y = 500(1.035)^x, indicates the value of an investment, where x is the number of whole years. What's the growth factor (the ratio from one year to the next)?

Answers

Given:
model y = 500(1.035)^x is the value of the an investment after x years.

the growth factor of this model is 1.035

Let us assume that x = 3 and x = 2

y = 500(1.035)² = 500 (1.07) = 535
y = 500(1.035)³ = 500 (1.11) = 555

growth factor = 555 / 535 = 1.037 or 1.035 

Alan can chop 3/4 of a carrot in 1/8 min.How many carrots can he chop in 1 min?

(I want to see how fast Brainly is)

Answers


(3/4 carrot) / (1/8 minute) = ('x' carrots) / (1 minute)

Cross-multiply the proportion:

   (3 carrot / 4 minutes) = ( 'x' carrot / 8 minutes)

Multiply each side by 8 minutes:

               6 carrots  =  'x' carrots


well 3/4 in 1/8 means that you need to multiply 3/4 by 8 in order to make a whole minute
3/4 × 8/1 = 24/4
24/4=6
the answer is 6 carrots 
(pretty fast right?)

the Mclntosh family went apple picking. they picked a total of 115 apples. The family ate a total of 8 apples each day. after how many days did they have 19 apples left?

Answers

In the given question, all the information's that are required is already provided. based on these information's the correct answer can be easily deduced. The McIntosh family picked a total of 115 apples. the family ate a total of 8 apples per day. It is required to find the day after which there will be 19 apples left from the total of 115. Then firstly let us subtract 19 apples from the total of 115.
Number of apples left after deducting 19 apples = 115 - 19
                                                                             = 96
Now
8 apples are eaten by the McIntosh family in = 1 day
96 apples will be eaten by the McIntosh family in = 96/8
                                                                               = 12 days
So after 12 days, 19 apples will be left with the McIntosh family.

Answer:

19 apples will be left with the McIntosh Family
