Suppose pedro makes n = 30 rolls, and a 4 comes up 6 times out of the 30 rolls. determine the p-value of the test:

p-value =

to prove δxyz ≅ δmno using sss, you need to show the following:

  side 1             side 2               side 3

xy ≅ mn         yz ≅ no           xz ≅ mo

to prove δxyz ≅ δmno using sas knowing side xz and angle o, you need to show the following:

side 1             connecting angle           side 2

xz ≅ mo             ∠z ≅ ∠o                   yz ≅ no

step 1: simplify both sides of the equation.

23x − 19x + 5 = 20

23x + − 19x + 5 = 20

(23x + − 19x) + (5) = 20 (combine like terms)

4x + 5 =20

4x+5=20

step 2:

step 2: subtract 5 from both sides.

4x + 5 − 5 = 20 − 5

4x = 15

step 3: divide both sides by 4.

answer: x =

in decimal form: 3.75
