<em>Hi there!</em>

<em>~</em>

<em>What is </em> $x(x+2)$ <em> expanded?</em>

<em></em> $x(x+2)$ <em> in expanded form is :</em>

<em></em> $x^2 + 2x$ <em></em>

<em>Explanation :</em>

<em>Apply the distributive law: </em> $a( b + c ) = ab + ac$ <em></em>

<em></em> $x(x+2) = xx + x \times 2$ <em></em>

<em></em> $= xx + x \times 2$ <em></em>

<em>Then you simplify : </em> $xx + x \times 2 : x^2 + 2x$ <em></em>

<em></em> $= x^2 + 2x$ <em></em>

<em>❀Hope this helped you!❀</em>

How to do ratio equivalents

Oksi-84 [34.3K]

Equivalent Ratios. Students learn to find equal ratios by first writing the given ratio as a fraction, then multiplying the numerator and denominator of the fraction by the same number. For example, to find two ratios that are equal to 1:7, first write 1:7 as the fraction 1/7. I hope this helps

How is the number five and two hundred three thousandths written in standard form?

Andru [333]

Answer:

0.05203*10 to the power 2

Step-by-step explanation:

To get the standard form you divide a number in order to multiply it by a power of 10 to get the same number. So 5.203 in standard form is o.o5203 * 10 to the power 2. The 10 to the power 2 comes from the number of palces you move the comma/ decimal point to the left

What we know:
- number of meeting rooms = m
- chairs in each meeting room = 325

Since we need an equation to represent the number of chairs in m meeting rooms, we would multiply the amount of chairs per meeting room (325) by m. This amount is c. So the equation becomes:

c = 325m

Now the question asks for the amount of chairs if there are 7 meeting rooms in the hotel. To find this, substitute 7 for m into c = 325m.

c = 325m
c = 325(7)
c = 2275

Answer:
The equation is c = 325m, and the amount of chairs if m equals 7 is 2,275.

Binomial probability distributions depend on the number of trials n of a binomial experiment and the probability of success p on

FinnZ [79.3K]

The question is incomplete! Complete question along with answers and step by step explanation is provided below.

Question:

(a) Binomial probability distributions depend on the number of trials n of a binomial experiment and the probability of success p on each trial. Under what conditions is it appropriate to use a normal approximation to the binomial? (Select all that apply.)

nq > 10

np > 5

p > 0.5

np > 10

p < 0.5

nq > 5

(b) What is the probability of "12" or fewer successes for a binomial experiment with 20 trials. The probability of success on a single trial is 0.50. Use the normal approximation of the binomial distribution to answer this question. (Round your answer to four decimal places.)

Answer:

(a) The correct options are np > 5 and nq > 5

(b) P(x ≤ 12) = 0.8133

Step-by-step explanation:
