2 answers:

8 0

This should be in the biology section. A Punnett square is a table to show all the possible outcomes of two parents mating. Specifically it deals with the genotypes and genetic combinations going from known parents to unknown potential offspring.

Answer:

Explanation:

The Punnett square is a diagrammatic representation which involves a square that is used to predict the genotype of the offsprings after the cross breeding process. It was named by the Reginald Punnett. This diagram is drawn by the biologists so as to know the probability of occurrence of a particular genotype in the offsprings.

Tamara invests $8000 in two different accounts. The first account has a simple interest rate of 3% and the second account has a

Paraphin [41]

Answer:

$3200 at 3%
$4800 at 2%

Step-by-step explanation:

Interest earned is proportional to the interest rate, so if the interest earned is the same, the amounts invested must be inversely proportional to the interest rates. That is, for the 3% and 2% accounts, the ratio of money invested is 2:3.

In other words, 2/5 of the money ($3200) was invested at 3%, and 3/5 of the money ($4800) was invested at 2%.

_____

If you need an equation, you can let x represent the amount invested at the highest rate. Then 8000-x is the amount invested at the lower rate. For the interest in the two accounts to be equal, we have ...

3%·x = 2%·(8000-x) . . . . . the amounts of interest earned are the same

3/2·x = 8000 -x . . . . . . . . divide by 2%

5/2·x = 8000 . . . . . . . . . . . add x and simplify

x = 8000·(2/5) = 3200 . . . multiply by the inverse of the x coefficient

8000-x = 8000 -3200 = 4800 . . . . the amount invested at the lower rate

Tamara invested $3200 in the 3% account and $4800 in the 2% account.

_____

She earned $96 in each account for the year.

MrRissso [65]

Answer:

40 students on each bus

Step-by-step explanation:

If you subtract the 4 students that traveled by car from the total 124 students, you are left with 120 students riding the 3 buses. Then, you would divide 120 by 3. (120 students divided by 3 buses.) 120/3 = 40

A sample of a radioactive substance decayed to 97% of its original amount after a year. (Round your answers to two decimal place

Alborosie

Answer:

23 years

Step-by-step explanation:

Step 1: Calculate the rate constant (k) for the radioactive decay

A radioactive substance with initial concentration [A]₀ decays to 97% of its initial amount, that is, [A] = 0.97 [A]₀, after t = 1 year. Considering first-order kinetics, we can calculate the rate constant using the following expression.

ln [A]/[A]₀ = - k.t

k = ln [A]/[A]₀ / -t

k = ln 0.97 [A]₀/[A]₀ / -1 year

k = 0.03 year⁻¹

Step 2: Calculate the half-life of the substance

We will use the following expression.

$t_{1/2}$ = ln2/ k = ln 2 / 0.03 year⁻¹ = 23 years

Compare the initial value and the range for each of the linear functions of f(x) and g(x)

Naily [24]

Answer:

Solution

First identify the input values. The input value is the first coordinate in an ordered pair. There are no restrictions, as the ordered pairs are simply listed. The domain is the set of the first coordinates of the ordered pairs.

D={2,3,4,5,6}

Next identify the output values. The output value is the second coordinate in an ordered pair. The range is the set of the second coordinates of the ordered pairs. Do not list the same output twice.
