Answer:

please mark me as brainlist please

Step-by-step explanation:

Correct option is B)

The circumference of the circle is 96 units.

Therefore, 2π×r=96

⇒r=

2×22

96×7

=15.27 units

Now, in the quadrilateral OLMN,∠OLM+∠LMN+∠MNO+∠NOL=360

Given that LM and MN are tangents to the circle, ∠OLM=∠ONM=90

∴∠NOL=360−90−90−60=120

The length of arc is given by rθ where θ is the angle made by the arc at the centre in radian.

Thus, arc length LN=15.27×

180

120π

=31.98

On a multiple choice test, if you randomly guessed on three questions, then what is the probability you got at least one of them

snow_lady [41]

Answer:

Number of Questions =3

Probability of giving a correct answer

$=\frac{1}{3}$

Probability of giving two correct answers

$=\frac{2}{3}$

Probability of giving all correct answers

$=\frac{3}{3}\\\\=1$

Probability that at least one of them is correct

$=_{1}^{3}\textrm{C}\\\\=\frac{3!}{(3-1)! \times1!}\\\\=3 \text{ways}\\\\=\frac{1}{3} \times \frac{1}{3} \times \frac{1}{3} \\\\=\frac{1}{27}$

Probability that two of them is correct

$=_{2}^{3}\textrm{C}\\\\=\frac{3!}{(3-2)! \times2!}\\\\=3 \text{ways}\\\\=\frac{2}{3} \times \frac{2}{3} \times \frac{2}{3} \\\\=\frac{8}{27}$

Probability that all of them is correct

$=_{3}^{3}\textrm{C}\\\\=\frac{3!}{(3-3)! \times3!}\\\\=1 \text{way}\\\\=1$

So, Required probability

$=\frac{1}{27} \times \frac{8}{27} \times 1\\\\=\frac{8}{729}$

52 is 130% of what number

In-s [12.5K]

So first you would cross multiply 52 by 100 which would get you 5200.

Next, you would divide 5200 by 130

Your answer would be 40
