The tens digit of a certain number is five more than the units digit. The sum of the digits is 9. Find the number.
Leokris [45]
<span>the tens digit = n
</span><span>the units digit = n-5

n + n-5 = 9
2n = 9+5
2n = 14
n = 7  </span>←  the tens digit

the units digit = n-5 = 7 - 5 = 2

<span>the number is 72</span>

The number of throws that the player make X follows binomial distribution.

The probability that the player makes x throws out of eleven throws is

P(X=x)=C(x,11)0.5^x(0.5)^{11-x}=C(x,11)0.5^{11}

The probability that the player makes at most nine out of eleven free throws

is

\sum_{x=0}^9C(x,11)0.5^{11}=1-\sum_{x=10}^{11}C(x,11)0.5^{11}\\ =1-C(10,11)0.5^{11}-C(11,11)0.5^{11}=1-\frac{12}{2^{11}} \\ =1-\frac{3}{512} =\frac{509}{512}

Correct choice is (B).

Use the image below to answer the following question. Find the value of sin x° and cos y°. What relationship do the ratios of si
stiks02 [169]

The relationship that sin x° and cos y° share is that; cos x = sin y and sin x = cos y = 12/13

<h3>How to work with Pythagoras Theorem?</h3>

From the definitions of trigonometric ratios, we know that;

sin x = opposite leg/hypotenuse

cos y = adjacent leg/hypotenuse

From the Pythagorean theorem, we can find the hypotenuse as;

6² + 8² = hypotenuse²

The cosine is the sine of the complementary angle. Since x and y are complementary angles as they sum up to 90°, we have cos x = sin y and sin x = cos y = 12/13
