Step-by-step explanation:

Length of arc of a circle is given as:

l =  \frac{ \theta}{360 \degree}  \times 2\pi \: r \\  \\  \therefore \: 14\pi = \frac{ \theta}{360 \degree}  \times 2\pi \:  \times 18 \\  \\ \therefore \:\theta =  \frac{14\pi \times \: 360 \degree }{2\pi \:  \times 18} \\  \\ \therefore \:\theta =  \frac{7 \times \: 360 \degree }{18}  \\  \\ \therefore \:\theta =  7 \times \: 20 \degree \\  \\  \huge \red{ \boxed{\therefore \:\theta =  140 \degree}}

Thus, the measure of central angle is 140°.

Tia performed an experiment where she flipped a coin 200 times. The coin landed heads up 92 times and tails up 108 times. Which
ra1l [238]

Total number of times she flipped a coin =200.

Total number of heads in the experiment=92

Total number of tails in the experiment=108

Therefore probability of the coun landing heads up in this experiment is 0.5

In the above experiment, the probability of the coin landing heads up is

P(H)= 92/200 = 0.46

In the above experiment, the probability of the coin landing tails up is P(T) = 108/200 = 0.54

The ratio obj represent the experimental probability of the coin landing heads up in this experiment

Therefore the correct option is 1.

Softa [21]

Answer:

i) Probability that both candidates employed are women = 5/14

ii) Probability that the second candidate is a woman = 5/8

iii) Probability that the first candidate is a woman given that second one is a woman = 4/5

Step-by-step explanation:

Let the probability that a man is employed be P(M) = 3/8

Probability that a woman is employed P(W) = 5/8

a) Probability that both candidates employed are women = (5/8) × (4/7) = 5/14

b) Probability that the second candidate is a woman = (probability that first candidate is a man and second candidate is a woman) + (probability that first candidate is a woman & second candidate is a woman)

= (3/8)(5/7) + (5/8)(4/7) = (15/56) + (20/56) = 35/56 = 5/8

c) Probability that the first candidate is a woman given that second one is a woman

Given that the second candidate was a women, means that the first candidate-women was selected among other four women.

Probability = (4/8)/(5/8) = 4/5

The segment from (-1,4) to (2,-2) extended three times then terminal point of segment is
ziro4ka [17]
There are various ways in which you could do this problem.  I'm going to share what I think is one of the faster ways.

Instead of thinking of jumping from (-1,4) TO (2,-2),  Consider the horiz. jump separately and the vertical jump separately.  From -1 to 2 is 3 units.  Three times that is 9 units.  Add 9 to -1, obtaining 8.  That's the horiz. component of the terminal point.

From 4 to -2 is -6 units.  Mult. that by 3.  The result is the vert. comp of the terminal point.

Which choice shows the following fractions with a common denominator? 3/4 and 5/6​
Roman55 [17]

Answer:

9/12 and 10/12

Step-by-step explanation:

The LCD is the smallest number divisible by both 4 and 6, and that is 12.

Thus, 3/4 and 5/6 are equivalent to 9/12 and 10/12 .

Next time, kindly share the answer choices.  Thank you.
