Which statement is TRUE?

Answer:

B) A random sample may represent the population <em>is your best answer.</em>

Step-by-step explanation:

Note that the answer choice says "may", which means that it doesn't <em>always</em> represent the population. Random samples means that they ask random people, and do not have a certain rule that they have to follow (such as recipients can only be a certain race, age, etc.) and that they can ask anybody they meet. This can give not only a higher chance of a general population's opinion, but also makes sure that there is not a high chance of obtaining misleading information.

For example, a random survey would not take place at a rally, in which most of the people would believe the same thing, and would answer fairly the same for the survey. Instead, a random survey may be taken at a busy intersection during the time when most people are out. You must note that though it has the best chance of getting a <em>more accurate</em> representation, it still isn't the most accurate. For the best accuracy, <em>everyone would have to answer the survey in which the survey question would affect</em>.

Step-by-step explanation:

The following relationships apply.

  • the diagonals of a parallelogram bisect each other
  • the diagonals of a rectangle are congruent
  • the diagonals of a rhombus meet at right angles
  • a rectangle is a parallelogram
  • a parallelogram with congruent adjacent sides is a rhombus

__

CEDF has diagonals that bisect each other, and it has congruent adjacent sides. It is a parallelogram and a rhombus, but not a rectangle. (B and C are true.)

ABCD has congruent diagonals that bisect each other. It is a parallelogram and a rectangle, but not a rhombus. (There is no indication adjacent sides are congruent, or that the diagonals meet at right angles.) (E and F are true.)

The true statements are B, C, E, F.

Pocahontas opens a savings account with $640 dollars that earns 3.9% interest per year not compounded. How much money to the nea
solmaris [256]

Given:

Principal value = $640

Rate of interest = 3.9% not compounded

Number of years = 8

To find:

The amount after 8 years.

Solution:

It is given that the interest is not compounded. It means, we need to find simple interest.

Formula for simple interest:

I=P\times r\times t

where, P is principal, r is rate of interest and t is time in years.

Put P=640, r=0.039 and t=8.

I=640\times 0.039\times 8

I=199.68

So, the interest is $199.68.

Now, amount after 8 years is

A=P+I

where, P is principal and I is interest.

A=640+199.68

A=839.68

Therefore, the amount after 8 years is $839.68.
