So heterozygous means one dominant trait and one recessive trait (Ll). Homozygous is either 2 recessive traits or 2 dominat. (in this case ll).
1.)Genotype: Ll and ll
Phenotype: 50% chance of Long pea plant, 50% chance of short.
2.) Genotype: Ww (widows peak) and ww (no widows peak)
Phenotypes: 75% chance of widows peak and 25% of no widows peak.
3.) Genotype: BB and Bb
Phenotype: 100% chance of black
First we need to find 75% of $450, so 450x.75=337.5
to find the markup we have to add 450+337.5 to get $787.5.
Original Conditional: If P, then Q
Inverse: If not P, then not Q
Using that template, the inverse would be "If I do not like math, then I do not like science" (simply insert those two "not" words keeping the order the same)
so the answer is choice C
Value of x = 7.499
Step-by-step explanation:
We need to find value of x in the equation: 
This can be solved using natural log
Solving:

Subtract 7 from both sides:

Simplifying:


Using rule if f(x)=g(x) then, ln(f(x))=ln(g(x))
So,

Applying log rule: logₐ(x^b)= b logₐ(x)

Divide both sides by 2ln(2)
So, Value of x = 7.499

Answer:
288
Step-by-step explanation:
If 52% studied French, then 48% didn't. The ratio of those who didn't to those who did is ...
(didn't study French)/312 = 48%/52% = 12/13
Then the number that didn't study French is ...
(didn't study French) = 312 × 12/13 = 288 . . . . . . multiply above by 312
288 students chose not to take French their Junior year.
