Answer:

72.9%

Step-by-step explanation:

Given that :

27.1% of all possible observation of a certain variable are less than 17 ;

That is ;

Let variable = y ;

Proportion of (y < 17) = 27.1% = (27.1 / 100) = 0.271

Proportion that lies to the right :

P(y > 17) = 1 - P(y < 17)

P(y > 17) = 1 - 0.271

P(y > 17) = 0.729 = 72.9%

svetoff [14.1K]

Answer:

19th day

Step-by-step explanation:

So say Lily was 1 when Lily was planted

First day Lily is 2

Second day Lily is 4

Third day Lily is 8

etc...

See the pattern?

The pattern is 2^x

On the 20th day, Lily was 2^20

So when Lily was half, Lily was 2^20 / 2

2^x = 2^20 / 2

2^x = 2^19

On the 19th day, Lily was half.

For an angle Θ with the point (12, −5) on its terminating side, what is the value of cosine?
Pachacha [2.7K]
Given that the point (12,-5) which takes the form (x,y), This implies that:
opposite=-5
adjacent=12
thus using using Pythagorean theorem, the hypotenuse will be:
c^2=a^2+b^2
plugging the values we obtain:
c^2=(12)^2+(-5)^2
c^2=144+15
c^2=169
thus
c=13
but
cos θ=adjacent/ hypotenuse
therefore:
cos θ=12/13

The area of a rectangle is 99 square units. Its width measures 9 units. Find the length of its diagonal. Round to the nearest te
mariarad [96]

Answer:

14.21 units (14.2)

Step-by-step explanation:

Formula for area is W(L) or width multiplied by length.

The formula for finding the length of a rectangle's diagonal is :

d = \sqrt{w^{2}+l^{2}  }

Now we solve for d.

d = \sqrt{w^{2} + (\frac{A}{W})^{2}

= \sqrt{9^{2} + (\frac{99}{9})^{2}

≈ 14. 21267

≈ 14.2
