Numbers less than 6,

$nth(5,4,3,2,1) = 5 \\ p(n < 6) = \frac{5}{8}$

The radius of circle O is 28, and OC =9. What is the length of AB?

aksik [14]

The answer:
the complement of the question proposed one of the choices given beneath:
a) 58.8
b) 53.0
c) 29.4
d) 26.5

as we observe at the figure, AOB an isosceles triangle, and OCB is a right triangle

consider OCB
OC =9, OB= radius = 28
the problem is how to find the length of CA, for that C is a midpoint of segment AB, so AC=BC

BC can be found by using pythagorean theorem
OB²= OC² + CB², this implies CB² = OB² - OC²

CB² = 28² - 9² = 784 - 81=703, therefore CB= sqrt (703)=26.51

CB=26.51, since CB= AC, so AC=CB= 26.51

finally the <span>the length of AB is AB = 2 x CB = 2x AC= 2x 26.51= 53.0
</span>
the answer is b) 53.0

Anthony jogs 11 1/2 miles in 23 mins. If Anthony continues to jog at a steady pace, how many miles will he jog each minute?

frozen [14]

For this case we can raise a rule of three based on Anthony trotting $11 \frac {1} {2}$ miles in 23 minutes.

$11 \frac {1} {2} = \frac {2 * 11 + 1} {2} = \frac {23} {2}$

$\frac {23} {2}$ miles -----------> 23 minutes

x ----------------------------------------> 1minute

$x = \frac {\frac {23} {2} * 1} {23}\\x = \frac {\frac {23} {2}} {23}\\x = \frac {23} {2 * 23}\\x = \frac {1} {2}$

ANswer:

0.5 miles per minute

James Priya and Siobhan work in a grocery store James makes 9.00!per hour Priya makes 40% more than James and Siobhan makes 15%

ki77a [65]

<h2><em>James has $9 </em></h2><h2><em>Priya has $10.80 </em></h2><h2><em>Siobhan has $9.18 </em></h2><h2><em>because 9*20% is 1.8 so add that to 9 to get 10.80 then times 10.80 by 15% to get 1.62 so you subtract 1.62 from 10.80 to get $9.18 </em></h2>

Find the solutions for a triangle with a = 16, c =12, and B = 63º.

maks197457 [2]

Answer:

b. A = 71.6°; C = 45.40°; b =15.0

Step-by-step explanation:

The missing values can be found with the help of the Law of Cosine and properties of triangles:

Side b (Law of Cosine)

$b = \sqrt{a^{2}+c^{2}-2\cdot a \cdot c \cdot \cos B}$
