Step-by-step explanation:
let jon age be x
dad age is 2 of x i.e 2x
grandpa age is 7 + 3(x)
The sum of jon dad and grandpa age is 145 i.e
x + 2x + (7+3x) = 145
3x +. 7 + 3x = 145
6x = 145- 7
6x = 138
divide both sides by 6
x = 23
jon age is 23
while
grandpa age is
7 + 3(x)
7 + 3(23)
7 + 69
76.
Answer:
25 grams
Step-by-step explanation:
Good effort, but that's not quite right.
Let's call the daily amount of fiber needed x.
One serving of oatmeal provides 16% of the daily amount, or 0.16 x.
The rest of the daily amount is 21 grams.
Together, they add up to the total daily fiber:
0.16 x + 21 = x
Solving for x:
21 = 0.84 x
x = 25
You need 25 grams of fiber daily.
Let's check our answer. 16% of 25 is 4. 4 plus 21 equals 25. So it checks out.
Answer:
heterozygous (Aa) are 0.085 = or 8.54%
Step-by-step explanation:
The heterozygous individuals are carriers of the sickle cell trait. They have a genotype of Aa and are represented by the 2pq term
in the H-W equilibrium equations.
According to the question 0.2% of the population is affected with sickle cell anemia, thus q^2
= 0.2% = 0.002 in decimal. So, q =
sqr(q^2)
or sqr(0.002) =
0.04472
and p + q = 1, thus p = 1 – q = 1 – 0.04472 = 0.96
Thus, A allele has a frequency of 0.96 and the a allele has a frequency of 0.04472. Therefore, the
percentage of the population that is heterozygous (Aa) and are carriers is = 2pq = 2× 0.04472× 0.96 =0.085 = or 8.54%
= 
= k
