Answer:

see explanation

Step-by-step explanation:

sinX = \frac{opposite}{hypotenuse} = \frac{YZ}{XY} = \frac{\sqrt{119} }{12}

cosX = \frac{adjacent}{hypotenuse} = \frac{XZ}{XY} = \frac{5}{12}

Eric throws a biased coin 10 times. He gets 3 tails. Sue throw the same coin 50 times. She gets 20 tails. Aadi is going to throw
iren2701 [21]

Answer:

(1) The correct option is (A).

(2) The probability that Aadi will get Tails is \frac{2}{5}.

Step-by-step explanation:

It is provided that:

  • Eric throws a biased coin 10 times. He gets 3 tails.
  • Sue throw the same coin 50 times. She gets 20 tails.

The probability of tail in both cases is:

  • P(\text{Tail})=\frac{3}{10}
  • P(\text{Tail})=\frac{20}{50}=\frac{2}{5}

(1)

According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.

In this case we need to compute the proportion of tails.

Then according to the Central limit theorem, Sue's estimate is best because she throws it <em>n = </em>50 > 30 times.

Thus, the correct option is (A).

(2)

As explained in the first part that Sue's estimate is best for getting a tail, the probability that Aadi will get Tails when he tosses the coin once is:

P(\text{Tail})=\frac{20}{50}=\frac{2}{5}

Thus, the probability that Aadi will get Tails is \frac{2}{5}.

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal costs $78.64 before the discount, and
OLEGan [10]

Answer:

  $82.57

Step-by-step explanation:

The tip they leave is ...

  $78.64 × 0.20 = $15.73

The amount of the discount is ...

  $78.64 × 0.15 = $11.80

Then the total cost of the meal and tip is ...

  meal price - discount + tip

  $78.64 -11.80 +15.73 = $82.57

the length of a rectangle is three less than twice its width. If the perimeter is 48, find the length.
Alisiya [41]

length = 15

let the width = w then length = 2w - 3

Perimeter = 2(length + width)

                = 2(2w - 3 + w) = 2( 3w - 3) = 6w - 6 = 48

hence 6w = 48 + 6 = 54 ⇒ w =\frac{54}{6}= 9

Thus length = 2w - 3 = (2× 9) - 3 = 18 - 3 = 15
