Answer:

D.

Mean: 24.8

Median: 26

Mode: 26

Explanation:

The mean is the average. To find the average, add up all the numbers and divide by the amount of numbers there are.

30 + 26 + 25 + 11 + 34 + 20 + 26 + 26 = 198

Now, we divide by how many numbers we started out with (8).

198 divided by 8 = 24.75, rounded would be 24.8

To find the median, you arrange the numbers from smallest to largest, and find the middle number like this:

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the middle number is 26.

To find the mode, you arrange the number from smallest to largest, and find the number that appears more often.

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the number 26 appears the most often.

So, we end up with:

Mean: 24.8

Median: 26

Mode: 26

In maize, a dominant allele A is necessary for seed color, as opposed to colorless (a). Another gene has a recessive allele wx t

Gelneren [198K]

Answer:

1/2 Aa Wx wx (colored seeds, normal starch)
1/2 aa Wx wx (colorless seed, normal starch).

Explanation:

A (colored seed) is dominant over a (colorless)
Wx (normal starch) is dominant over wx (waxy)

Both loci are independent.

A Aa WxWx individual was test crossed (crossed with a homozygous recessive aa wxwx individual).

The homozygous recessive can only produce a wx gametes.
The dihybrid individual can produce two types of gametes, all of them with the same frequency because the genes segregate independently: 1/2 A Wx and 1/2 a Wx

The possible offspring resulting from the combination of those gametes is:

1/2 Aa Wx wx (colored seeds, normal starch)
1/2 aa Wx wx (colorless seed, normal starch).

Which part of the iceberg displaces water equal in weight to the buoyant force?explain.

ohaa [14]

The iceberg has weight Wi = Mig and the buoyant force is equal to the weight of the displaced water, Ww = Mwg. Furthermore, since the iceberg is floating, its weight exactly balances the buoyant force:

Ww = Wi
Mwg = Mig
VwRhowg = ViRhoig
Vw = Rhoi/Rhow Vi

So, the fraction of ice underwater, Vw/Vi, is given by the ratio of densities Rhoi/Rhow=0.87. Over 87% of an iceberg's volume (and mass) is underwater. As you can see, the convenient definition of the gram gives us a quick way to see how much of a floating substance lies below the surface of fresh water: the fraction is equal to that substance's mass density in g/cm?.

Summary

Archimede's Principle of bouyancy states that the bouyant force on an object is equal to the weight of the fluid displaced by that object.The underwater fraction of a substance floating on water is given by that substance's mass density in g/cm3.

Which groups of people can’t get vaccines because of possible negative side effects? ASAP

rewona [7]

Answer:

I hope this answers your question. Some people can't get certain vaccines when they are certain ages. If you are too young(just born) or too old, you may not want to have vaccines that can be hard on your body. People with certain health risks shouldn't get vaccines either. Another example would be someone has a severe reaction to a vaccination, they shouldn't get a booster for the vaccine in the future.
