Answer:

2/91.

Step-by-step explanation:

There are 15 marbles in the bag.

Prob(First draw is red) = 5/15 = 1/3.

Prob(Second draw is red) = 4/14 = 2/7.

Prob(Third draw is red) = 3/13.

So probability that all 3 are red = .1/3 * 2/7 * 3/13

= 6/273

= 2/91.

Answer:

Answer:

5/13, 12/5, 12/13

Step-by-step explanation:

cos = adj/hyp

tan = opp/adj

sin = opp/hyp

hyp = 13

adj = 5

opp = 12

Plug in.

cos = 5/13

tan = 12/5

sin = 12/13

Answer:

A refund must be above $7,139 before it is audited.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 7010, standard deviation = 43.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

The empirical rule is symmetric, which means that the lowest (100-99.7)/2 = 0.15% is at least 3 standard deviations below the mean, and the upper 0.15% is at least 3 standard deviations above the mean.

Use the Empirical Rule to determine approximately above what dollar value must a refund be before it is audited.

3 standard deviations above the mean, so:

7010 + 3*43 = 7139.

A refund must be above $7,139 before it is audited.

Answer:

the angle that is 110° and 30°

Step-by-step explanation:

The triangle is similar to triangle T is triangle III.

Thus, option (c) is correct.

In the given triangle,

Two angles are 110 and 40.

Using Angle sum property in given triangles as

Angle 1 + Angle 2 + Angle 3 = 180

110 + 40 + Angle 3= 180

150 + Angle 3= 180

Angle 3 = 180 - 150

Angle = 30

Thus, the angles are 110, 40 and 30.

Therefore, Triangle III is similar to triangle T.

4=x  answer.

========================================================

Explanation:

Angles EGD and BGF are vertical angles. Both are unknown and equal to x.

Notice how angle AGD is adjacent to angle CGD. These two angles form a straight angle (180 degrees) and angle CGD is a right angle. That must mean AGD is also a right angle.

Angles AGE and EGD must add to 90 degrees since AGD is 90

----------

(angleAGE)+(angleEGD) = (angle AGD)

(30) + (x) = 90

x = 90-30

x = 60

{0} ∈ Z ∧ {0} ∉ N

Step-by-step explanation:

The notations we can use here are:

∈ = belongs

∉ = does not belong.

∧ = and

So, if we want to say that 0 is an integer, we use:

{0} ∈ Z

if we want to say that 0 is not a natural number, we use:

{0} ∉ N

And, if we want to say both in the same statement, we can use the "and" symbol:

{0} ∈ Z ∧ {0} ∉ N

There is no solution.

Step-by-step explanation:

Given:

y = 2x + 1

4x - 2y = 4

Substitute y = 2x + 1 into 4x - 2y = 4

4x - 2(2x + 1) = 4

4x - 4x - 2 = 4

0x = 4 + 2

0x = 6

Anything to the multiple of zero is zero. Hence 0x = 0, and 0 ≠ 6

So there is no solution to the equation.

The fraction of the whole pan of cornbread each child will get is 1/12.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, 1/3 of a pan of cornbread shared among 4 children.

Here, cornbread share of each child = Total quantity of bread/Number of children

= 1/3 ÷ 4

= 1/3 × 1/4

= 1/12

Therefore, the fraction of the whole pan of cornbread each child will get is 1/12.

Answer:

[tex] x_{1} = 3 + \sqrt {6} [/tex]

[tex] x_{2} = 3 - \sqrt {6} [/tex]

Step-by-step explanation:

Given the quadratic equation;

x² - 6x + 3 = 0

To find the roots of the quadratic equation, we would use the quadratic formula;

Note: the standard form of a quadratic equation is ax² + bx + c = 0

a = 1, b = -6 and c = 3

The quadratic equation formula is;

[tex] x = \frac {-b \; \pm \sqrt {b^{2} - 4ac}}{2a} [/tex]

Substituting into the formula, we have;

[tex] x = \frac {-(-6) \; \pm \sqrt {-6^{2} - 4*1*(3)}}{2*1} [/tex]

[tex] x = \frac {6 \pm \sqrt {36 - (12)}}{2} [/tex]

[tex] x = \frac {6 \pm \sqrt {36 - 12}}{2} [/tex]

[tex] x = \frac {6 \pm \sqrt {24}}{2} [/tex]

[tex] x = \frac {6 \pm 2 \sqrt {6}}{2} [/tex]

[tex] x_{1} = \frac {6 + 2 \sqrt {6}}{2} [/tex]

[tex] x_{1} = \frac {6}{2} + \frac {2 \sqrt {6}}{2} [/tex]

[tex] x_{1} = 3 + \sqrt {6} [/tex]

Or

[tex] x_{2} = \frac {6 - 2 \sqrt {6}}{2} [/tex]

[tex] x_{2} = \frac {6}{2} - \frac {2 \sqrt {6}}{2} [/tex]

[tex] x_{2} = 3 - \sqrt {6} [/tex]
