Answer:

The Answers are

$\csc (-45) =-\sqrt{2} \\\\\sec (-45) = \sqrt{2}\\\\\cot (-45) = -1$

Step-by-step explanation:

Let we Know some Identities

cosec (-θ) = - cosec (θ)

sec (-θ) = sec (θ)

cot (-θ) = - cot (θ)

Also,

$\csc (45) =\sqrt{2} \\\\\sec (45) = \sqrt{2}\\\\\cot (45) = 1$

Therefore,

$\csc (-45) =-\csc (45)=-\sqrt{2} \\\\\sec (-45) =\sec (45) =\sqrt{2}\\\\\cot (-45) =-\cot (45)= -1$

blsea [12.9K]

Answer: The probability that the fruit is an orange or a pear is $\dfrac{1}{3}$ .

Step-by-step explanation:

Given : Emily has 12 fruits in her bowl.

She has 3 apples, 5 bananas, 1 pear and 3 oranges.

A fruit is selected at random.

P(orange) = $\dfrac{\text{Number of oranges}}{\text{Total fruits}}$

$=\dfrac{3}{12}$

P(pear)= $\dfrac{\text{Number of pears}}{\text{Total fruits}}$

$=\dfrac{1}{12}$

Since both events of selecting orange and pear are mutually exclusive , so

The probability that the fruit is an orange or a pear = P(orange) + P(pear)

$=\dfrac{3}{12}+\dfrac{1}{12}=\dfrac{4}{12}=\dfrac{1}{3}$

Therefore , the probability that the fruit is an orange or a pear is $\dfrac{1}{3}$ .
