Which statement is true:

a) Jill will make less money if they each work 4 hours.

b) Jill's hourly rate is $3 more than kara's.

c) Kara charges $14 and hour for babysitting two children.

d) Kara's fee for the second child is $5.

Answer:

(D)Kara's fee for the second child is $5.

Step-by-step explanation:

$\left|\begin{array}{c|c|c}$Time(hr)&$Jill: Cost for Two Children& $Kara: Cost for Two Children\\-----&------&-----\\1&11&14=9+5\\2&22&23=9(2)+5\\3&33&32=9(3)+5\end{array}\right|$

From the table above,

Jill Charges an hourly rate of $11

Kara charges an hourly rate of $9 and an additional $5 charge for more than one child. Therefore, the statement that is true is Option D.

Kara's fee for the second child is $5.

All other options are incorrect.

<u>Check</u>

Option A: In four hours, Jill will make $44 while Kara will make $41

Option B: Jill's hourly rate is $2 more than Kara's, NOT $3.

Option C: Kara charges $9 an hour, NOT $14.

Svetach [21]

Answer:

10 classes

Step-by-step explanation:

Ok, so to solve this we have to make two different equations. we can say 60x = y, or $60 per month, and 6a = b, or $6 per walk in. Since we want the options to end up costing the same, we can say that y = b. With substitution, we get that 60x, (60 per month) = 6a (6 per drop in). The question says we have 1 month, so x = 1. This means we have 60 = 6a, and a = 10 (10 classes).

A plant can either have a smooth seed (p) or a rough seed (q). Rough seeds are recessive and smooth seeds are dominant. In a pop

To calculate this, the Hardy-Weinberg principle can be used:

p² + 2pq + q² = 1 and p + q = 1

where p and q are the frequencies of the alleles (p - dominant, q - recessive), and p², q² and 2pq are the frequencies of the genotypes.

a) Since 32 plants have rough seed (recessive genotype: q²) out of 100 plants in total, then

q² = 32/100 = 0.32

b) q = √q² = √0.32 = 0.56

c) Since p + q = 1, then
