Lets write this out:-

\frac{50}{100} + \frac{30}{100}

To answer this we just need to add the numerators of both fractions because the denominator's are already common multiples. 

\frac{50}{100}+ \frac{30}{100} = \frac{80}{100}

Now lets simplify \frac{80}{100}.

\frac{80/20}{100/20}=  \frac{4}{5}

So, \frac{50}{100}+  \frac{30}{100} = \frac{80}{100}= \frac{4}{5}

Hope I helped ya!! xD

\frac{50}{100} + [tex] \frac{30}{100}[\tex]. Just multiply the numerators. The denominator is already a common denominator.

Discuss the conditions under which P(A or B)= P(A) + P(B) is true
Andrews [41]
That condition is true if P(A) and P(B) are independent of one another. For example, if I was pulling marbles out of a bag, if I am replacing the marbles back after I pull one out, then P(A or B) = P(a)+P(B).

Solve for x. Round your answer to the nearest hundredth.
Dmitriy789 [7]

Answer:


Step-by-step explanation:

Here we need to find the x for the given equation so we can use the concept of the quadratic formula to solve .

comparing the given equation with an standard quadratic equation we get

a=1

b=6

c=3

so applying the quadratic formula we get

x=\frac{-6+-\sqrt{6^2-4*1*3} }{2*1}

x=\frac{-6+-\sqrt{24} }{2}

which can be further simplified to get

x=-5.45 or x=-0.55

so correct option is <em>A</em>

Help!!!!!!! v is a vector of magnitude 4 making an angle of 30° with the positive x-axis. find v in component form .
Elodia [21]

Since v is a vector of magnitude 4 and makes angle 30° with the positive x axis, vector v in component form is v = 2√3i + 2j

To find vector v in component form, we need to know what a vector is

<h3>What is a vector?</h3>

A vector is a physical quantity that has both magnitude and direction.

<h3>Component of a vector</h3>

A vector can be resolved into perpendicular components along the x, y and z axis.

<h3>Components of vector v</h3>

Since vector v has a magnitude of 4 making an angle of 30 with the positive x - axis, its x-component is V = (vcos30°)i

= (4cos30°)i

= (4 × √3/2)i

= 2√3i.

The y-component of v is V' = (vsin30°)j

= (4 × sin30°)j

= (4 × 1/2)j

= 2j

<h3>Vector v in component form</h3>

So, vector v in component form is v = V + V'

= 2√3i + 2j

So, since v is a vector of magnitude 4 and makes angle 30° with the positive x axis, vector v in component form is v = 2√3i + 2j
