Since the spinner is labelled A, B, C, D, there are four possible landing for the spinner.

Thus, the sample space is {A, B, C,D}.

Therefore, the number of <span>elements in the sample space for spinning a spinner labeled A, B, C, D</span> is 4.

If sin(x) = 0.28, what is cos(90° - x)

vlabodo [156]

$\bf \textit{Cofunction Identities}
\\\\
sin\left(\frac{\pi}{2}-\theta\right)=cos(\theta)
\qquad 
cos\left(\frac{\pi}{2}-\theta\right)=sin(\theta)
\\\\\\
tan\left(\frac{\pi}{2}-\theta\right)=cot(\theta)\qquad 
cot\left(\frac{\pi}{2}-\theta\right)=tan(\theta)
\\\\\\
sec\left(\frac{\pi}{2}-\theta\right)=csc(\theta)\qquad 
csc\left(\frac{\pi}{2}-\theta\right)=sec(\theta)$

therefore, sin(x) = cos(90° - x).

PLEASE ANSWER HURRY THANK YOU

Answer: A. $\dfrac{6}{203}$

Step-by-step explanation:

Given : Jason bought 10 of the 30 raffle tickets for a drawing.

i.e. Total tickets = 30

Also, Number of prizes = 3

The total number of combinations of getting 3 prizes out of 30 tickets = $^{30}C_3$

The number of combinations of getting 3 prizes out of 10 tickets = $^{10}C_3$

Then, the probability that Jason will win all 3 of the prizes if once a raffle ticket wins a prize it is thrown away will be :

$\dfrac{{^{30}C_3}}{^{10}C_3}$

$=\dfrac{\dfrac{10!}{3!7!}}{\dfrac{30!}{3!27!}}=\dfrac{120}{4060}=\dfrac{6}{203}$

Hence, the probability that Jason will win all 3 of the prizes if once a raffle ticket wins a prize it is thrown away is $\dfrac{6}{203}$ .

Hence, the correct answer is A. 6/203.

A watch was bought for Rs 1200. At what labeled price should it be sold to gain 33.33% after 20% discount find SP with 13% vat o

fgiga [73]

Answer:

Lebeled Price of watch = Rs. 2000

Selling price pf the watch = Rs. 1600

Step-by-step explanation:

∴ S = L - 20% L
∴ S = 0.8 L ..... (1)
∴ S = P + (1/3)P
∴ S = (4/3) P ..... (2)
As we know, P = 1200
∴ S (4/3) × 1200
∴ S = Rs. 1600
1600 = 0.8L
∴ L = 1600 ÷ 0.8
∴ L = Rs.2000
∴ Lebeled Price of watch = Rs. 2000
Selling price pf the watch = Rs. 1600
