Which expressions show the expanded form for 200.06? Choose all answers that are correct. A. 2 × 100 + 0 × 1 + 0 × 1/10 + 6 × 1/
saveliy_v [14]

Answer:

Therefore,

Correct options are

A)  2 × 100 + 0 × 1 + 0 × 1/10 + 6 × 1/100

D) 2 × 100 + 6 × 1/100

Step-by-step explanation:

Given:

Number is

200.06

For option A)

2 × 100 + 0 × 1 + 0 × 1/10 + 6 × 1/100

= 200 + 0 + 0 + 0.06

= 200.06

Which is CORRECT.

For option B)

2 × 100 + 0 × 1 + 0 × 1/100 + 6 × 1/1,000

= 200 + 0 + 0 + 0.006

=200.006

Which is INCORRECT.

For option C)

2 × 100 + 6 × 1/10

= 200 + 0.6

= 200.6

Which is INCORRECT.

For option D)

2 × 100 + 6 × 1/100

= 200 + 0.06

= 200.06

Which is CORRECT.

Therefore,

Correct options are

A)  2 × 100 + 0 × 1 + 0 × 1/10 + 6 × 1/100

D) 2 × 100 + 6 × 1/100

What is the recursive formula for the geometric sequence with this explicit formula?
IRINA_888 [86]

For the given geometric sequence, we have:

a_1 = 9\\\\a_n = (-1/3)*a_{n-1}

So the correct option is B.

<h3>Which is the recursive formula?</h3>

Here we have the geometric sequence:

a_n = 9*(-\frac{1}{3} )^{(n - 1)}

To get the initial value of the geometric sequence, we just need to replace n by 1, so we get:

a_1 = 9*(-\frac{1}{3} )*(1 - 1) = 9

Now, notice that the common ratio is (-1/3), this means that each term of the sequence is (-1/3) times the previous term.

a_n = (-1/3)*a_{n-1}

Then the correct option is B.

In a hypothesis test, what should we conclude if the data would be very unusual if the original assumption about our parameter w
Triss [41]

We conclude  the hypothesis test as Alternative Hypothesis if the data would be very unusual if the original assumption about our parameter were correct.

  • A hypothesis in statistics is a claim or supposition on the properties of one or more variables in one or more populations. There are two hypothesis to choose between because a statement might either be true or wrong.
  • The null hypothesis is the assertion that we (or someone else) consider to be true. Our hypothesis test will come to one of two conclusions: "reject H0" or "do not reject H0." Remember that until data provide evidence to the contrary, we always proceed under the null hypothesis.
  • If the null hypothesis is incorrect, the alternative hypothesis must be true. The hypothesis test can be different in one of three ways: greater than, smaller than, or just different (not equal). As a result, there will always be an inequality requirement in the notation for H.
