Yes it's SAS
AD = CD (given)
BD = BD (common side )
but since it didn't say AC丄BD
it's no way to prove the angels r 90° :/
but as it already given AD= CD
so it's proven that it's an isosceles triangle
therefore
∠BAD = ∠BCD (base ∠s isos. ∆)
therefore it's SAS (side angel side)
The first one has 2 like terms one is -4 and the other is * the 2nd question does have a like term z2 and z3 question 4 has 1 like term y3 and the last question has 4 like terms every number is a like term of each other
Total customers: 26+42+33+24+40 =
165
The number of customers that bought 5-6 = 33
The probability would be 33/165
Total customers that bought fewer than 5 = 26+42 = 68
The probability is 68/165
