When two probabilities

Mathematics
1 answer:
Ivenika [448]3 years ago
7 0

Answer: True  

Step-by-step explanation: Because if we have two independent events and want to know the probability of their happening at the same time, we multiply the two probabilities together.  "Two events happening at the same time" is a compound event.  We more often see this as "P(xy)," the probability of x AND y.

Find the equivalent fraction or decimal for each number.<br><br> 0.6=
mezya [45]

we can convert any decimal value to a fraction by simply <u>using in the denominator a power of 10 with as many zeros as there are decimals and lost the dot above</u>, this one has one decimal, so we'll use 1 zero, and lose the dot above.

\bf 0.\underline{6}\implies \cfrac{06}{1\underline{0}}\implies \cfrac{~~\begin{matrix} 2 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~\cdot 3}{~~\begin{matrix} 2 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~\cdot 50}\implies \cfrac{3}{50}

Which of the following equations can be used to find the length of EF in the
Vinil7 [7]

The equation which can be used to find the length of EF is option A which is  EF=\sqrt{24^{2} -12^{2} }.

Given the length of base of right angled triangle is 12 and the hypotenuse be 24.

We are to find the length of EF and tell which equation can be used to find the length of EF.

We know that pythagoras theorem applies in a right angled triangle.

Pythagoras theorem says that in a right angled triangle the square of the hypotenuse is equal to the sum of square of base and perpendicular.

H^{2} =B^{2} +P^{2}

In this triangle we are only given base and hypotenuse and we have to find EF which is perpendicular.

(DE)^{2} =(EF)^{2} +(DF)^{2}

EF=\sqrt{DE^{2}-DF^{2}  }

=\sqrt{(24)^{2} -(12)^{2} }--1

=\sqrt{576-144}

=\sqrt{432}

Hence the equation which can be used to find the length of Ef is option A which is  EF=\sqrt{24^{2} -12^{2} }.

Question is incomplete as it should include the figure also.

What is the measure on an interior angle of this polygon?
Karo-lina-s [1.5K]

Answer:

a) 160°

b) 18 sides

Step-by-step explanation:

Interior angle = 180 - exterior

= 180 - 20 = 160°

Each angle of a regular polygon:

[(n-2)×180]/n = 160

180n - 360 = 160n

20n = 360

n = 18

Alternate approach for no. of sides:

360/n = each exterior angle

360/n = 20

n = 360/20 = 18
