Fraction would be 30/100 and decinal would be .30 and ratio would be 30/100
babymother [125]3 years ago

2.) the fraction is 3/10 because there are 100 blocks and 30 of them are filled
Decimal is .3 because it is 30% of 100
The ratio is 3:10

3.) part is 40 because 50% of 80 is 40 and whole is 80 because that’s the full number without the percentage, percentage is 50 because 50% is the percentage you have to get this means it’s 40/80 = 50/100 we know this is correct because they both simplify to 1/2=50%

SIZIF [17.4K]

Answer:

Step-by-step explanation:

(2/5 * 30) * 6^2 - 3^2           Reduce 2/5 * 30

180 * 6^2 - 3^2                    Raise the bases of the power

180 *36 - 9                           Multiply 36 and 180

9. Use the rule of multiplication to calculate the probability that a particular F2 individual will be homozygous recessive or d
Bess [88]

Answer:

Complete: (1/2 dominant. + 1/2 recessive.)2

Homozygous. recessive.: 1/2 recessive. x 1/2 rec. = 1/4 rec.-rec.

Homozygous. dominant.: 1/2 dominant. x 1/2 dominant. = 1/4 dom.-dom.

Step-by-step explanation:

First, let us understand what the rule of multiplication is all about:

Basically, the rule of multiplication is a rule that states that there is a probability that two independent parallel event will eventually meet at a point.

Referring back to the question and applying the rule of multiplication,

we have,

Complete: (1/2 dominant + 1/2 recessive.) 2

Homozygous. recessive.: 1/2 rec. x 1/2 rec. = 1/4 recessive.-rec.

Homozygous. dominant.: 1/2 dom. x 1/2 dom. = 1/4 dom.-dom.
