Write each number in expanded form one

1 answer:

8 0

We need the numbers but here's an example.

Expanded form is:

100+20+4
So if you do it in simple form it's 124. Because there's 100, 20, and 4.

Step-by-step explanation:

We wanna have the same amount on both sides

There are 3 circles on the left and 7 circles on the right. There are also 4 triangles. Turn into numbers...

4x+3=7

4x=7-3

x=1

We can check by substituting one

7=7

Assume that a population of 50 individuals has the following numbers of genotypes for a gene with two alleles, B and b: BB = 30,

Andreas93 [3]

Answer:

the frequency of allele B is 0.7 and allele b is 0.3 in population’s gene pool.

Step-by-step explanation:

Allele frequency is how often an allele occurs in a gene pool relative to the other alleles for that gene

Genotype No. of Individuals No. of Allele B No. of Allele b

BB 30 30*2 =60 30*0 =0

Bb 10 10*1 =10 10*1=10

bb 10 10 *0 =0 10*2=20

Total 50 70 30

Total no. of alleles = 70+30 =100

The frequency of allele B : $\frac{\text{number of B alleles}}{\text{total number of alleles}}$

: $\frac{70}{100}$

: $0.7$

The frequency of allele b : $\frac{\text{number of b alleles}}{\text{total number of alleles}}$

: $\frac{30}{100}$

: $0.3$

Hence the frequency of allele B is 0.7 and allele b is 0.3 in population’s gene pool.

Given a population of class sizes at a university in an academic year, indicate what the sampling distribution for samples of 3

drek231 [11]

Answer:

Step-by-step explanation:

sampling distribution is statistical representation of statistics of each sample. So for a class size of 30,

A. number of samples have to be very large and defined in sampling distribtuion so this option is nullified

B. sample collection in sampling distribution is done without replacement of individuals so this option is nullified

C. this explanation doesn't match with the definition so this option is nullified

D. It is the correct option
