Answer:

A

Step-by-step explanation:

y = 20(0.5^x)

x = 1, y = 20(0.5) = 10

x = 3, y = 20(0.5³) = 2.5

Grace rolls a fair, 6-sided die 50 times.
Lostsunrise [7]

Answer:

Step-by-step explanation:

Here's the thing. It is easier to figure out the probability of not getting a six even once during the 50 rolls.

The chance of that happening is (5/6)^50 = 0.00010988

So the probability is succeeding is (1 - 0.00010988) = 0.9999 rounded to 4 places.

Which system of equations has the same solution as the system below?
worty [1.4K]

Answer: Both A, and C

Step-by-step explanation:

The answer to the first system of equations (2x+2y=16) would be

x=3 and y=5 ( 3x-y=4 )

Which means we have to find out which of the other equations has an x value of 3, and a y value of 5.

If A is 2x+2y=16, then x=3 and y=5

           6x-2y=8

If B is x+y=16, then x=5 and y=11

         3x-y=4

If C is 2x+2y=16, then x=3 and y=5

           6x-2y=8

If D is 6x+6y=48 , then x=-2 and y=10

            6x+2y=8

Both A and C are equal to the first system of equations, which means they are both correct answers.

Answer:

Question 37:

B) 21

Step-by-step explanation:

How I found the radius:

radius= 132/ 2 x π  

r=132 / 6.2831853071796

r=21.0084525

Divide 132 by 6.2831853071796

π = 3.1415926535898

Note: Hope this Helps!
