What is the probability of rolling two 5? P(5,5)

Mathematics
1 answer:
dexar [7]3 years ago

Answer:

This question is almost impossible to answer, because some numbers are more likely to be rolled than others, but for the purposes of this question, the answer is 1 in 36.

Step-by-step explanation:

Assuming that all numbers are equally likely to be rolled, the answer is 1 in 36.  For just one 5, the answer is 1 in 6, because there are 6 sides on a dice, and the number five is only on one side of that dice. However, we are talking about two 5s, so we need to multiply 1 in 6 by 1 in 6, or 1/6 x 1/6, which equals 1/36.

Hope this helped! If it did, please give me brainliest! It would help a lot! Thanks! :D

The angles of a pentagon are x, x − 5 0 , x + 100 , 2x + 150and 2x + 300 . Find all the angles.
miv72 [106K]

Answer:

The interior angles are 70°,65°,80°,155° and 170°

Step-by-step explanation:

step 1

Find the sum of the interior angles of the pentagon

The sum is equal to

S=(n-2)*180°

where

n is the number of sides of polygon

n=5 (pentagon)

substitute

S=(5-2)*180°=540°

step 2

Find the value of x

Sum the given angles and equate to 540

x+(x-5)+(x+10)+(2x+15)+(2x+30)=540°

7x+50=540°

7x=490°

x=70°

step 3

Find all the angles

x=70°

(x-5)=(70-5)=65°

(x+10)=(70+10)=80°

(2x+15)=(2*70+15)=155°

(2x+30)=(2*70+30)=170°

24+z/10 = 31 solve for Z
cestrela7 [59]
Z=70

Simplify both sides of the equation
Subtract 24 from both sides
Multiple both sides by 10

What are the solutions to the equation x² = 625?
Hoochie [10]
The correct answer would be B. Because if you multiply -25 * -25 (because the x has 2 to the second power) the answer would be 625 :)
Hope I helped.

the radius of a circle is 10 using pi which equation expresses the ratio of the circumference of the circle to the circle's diam
grigory [225]

Answer:

pi

Step-by-step explanation:

The radius of the circle is 10 units

The circumference of a circle is given by the formula:

  C = 2 * pi * r

The diameter of a circle is twice the radius

d= 2r

We want the ratio of the circumference to the diameter

C/d  = (2*pi*r)/ 2r  

Canceling out the 2 and the r, we are left with pi

C/d = pi
