What is the value of x?

Elanso [62]

Since all the angles are congruent, the sides must be congruent too.

So, just have one equation on one side equal to another.

5x= 3x+6

Subtract 3x from both sides.

2x=6

Divide 2 into both sides.

x=3.

We can check this by seeing if all the sides are the same.

5(3)= 15

6(3)-5= 15

3(3)+6= 15

I hope this helps!

Ms. Smith puts a variety of wrapped

marusya05 [52]

Using the binomial distribution, it is found that the number of students that would be expected to select a gold-wrapped candy from the bag is given by:

B. 5 students

The candies are chosen with replacement, which means that for each student, the probability of choosing a gold wrapped candy is independent of any other student, hence the binomial distribution is used.

<h3>What is the binomial distribution?</h3>

The <em>binomial distribution</em> is the <u>probability of exactly x successes on n repeated trials, with p probability of a success on each trial</u>.

The expected value of the binomial distribution is:

$E(X) = np$

In this problem:

There are 15 students, hence $n = 15$ .

Of a totlal of 5 + 1 + 2 + 4 = 12 candies, 4 are gold wrapped, hence $p = \frac{4}{12} = \frac{1}{3}$

Then, the <em>expected value</em> is:

$E(X) = np = 15\times \frac{1}{3} = 5$

Hence, option B is correct.

Solve the equation for b 5= 3/2 (3) + b

kaheart [24]

Answer:

The answer is b = 1/2

Step-by-step explanation:

1) Use this rule: a/b × c = ac/b.

$5 = \frac{3 \times 3}{2} + b$

2) Simplify 3 × 3 to 9.

$5 = \frac{9}{2} + b$

3) Subtract 9/2 from both sides.

$5 - \frac{9}{2} = b$

4) Simplify 5 - 9/2 to 1/2.

$\frac{1}{2} = b$

5) Switch sides.

$b = \frac{1}{2}$

<u>Therefor</u><u>,</u><u> </u><u>the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>b</u><u> </u><u>=</u><u> </u><u>1</u><u>/</u><u>2</u><u>.</u>
