Answer:

Jason is 14 year old.

Step-by-step explanation:

Given: Joe, John and Jason are each a year apart in age.

           Sum of their age is 39.

Lets assume the age of Joe be x

∴ Age of Jahn will be (x+1)

And age of Jason will be (x+2)

Now, putting up an equation for the sum of their age.

∴ x+(x+1)+(x+2)= 39

Opening the parenthesis.

⇒x+x+1+x+2= 39

⇒3x+3= 39

Subtracting both side by 3

⇒ 3x= 36

Dividing both side by 3

⇒x= \frac{36}{3}

∴ x= 12\ years

Hence, Joe is 12 year old.

Next subtituting the value of x to find age of Jason and John.

Jason= (x+2)= 12+2

∴Jason= 14 years.

John age= (x+1)= 12+1

∴ John Age= 13 years.

Hence, Jason is 14 year of age.

Given the frequency table on the relationship between red hair and green eyes.
                       Green Eyes            Eye Color other than Green             Total
Red Hair                18                                       29                                    47

Hair Color
other than             114                                     650                                  764

Total                     132                                     679                                   811

The relative frequency table is obtained from a frequency table by dividing each entry of the requency table by the overall total of the frequency table.

The relative frequency table of the frequency table above is given below.
                       Green Eyes              Other Eye Color                    Total
Red Hair   18/811 = 0.02 = 2%      29/811 = 0.04 = 4%    47/811 = 0.06 = 6%

Other Hair
Color       114/811 = 0.14 = 14%|650/811 = 0.80 = 80%|764/811 = 0.94 = 94%

Total        132/811 = 0.16 = 16%|679/811 = 0.84 = 84%|811/811 = 1.0 = 100%

Given that x is the relative frequency of people that have other hair color and have green eyes, thus, the value of x is 14%.

Therefore, <span>the value of x in the table = 14%.</span>

Factor 3h2 – 11h - 42
Zina [86]
The answer is D
3*-42=-126
The factors of -126 that add to -11 are 7 and -18
replace -11h with 7h-18h
3h^2 + 7h - 18h - 42
Factor the first two terms and last two terms
h(3h+7) - 6(3h+7)
See how the two parentheses are the same?
THE ANSWER IS BELOW!!
(h-6)(3h+7)
the first parentheses has the terms that were outside, and the second has the original bracketed terms
This matches option D (it just multiplies the terms backwards, which gives the same result)
