Answer:
probability of x is 0.22 correct to two decimal places
Step-by-step explanation:
step 1. use the poisson formula given as
p(x) = (λˣe∧-λ) ÷x! where λ is the mean and it called lambda,λ = 3, e is mathematical constant and it approximately = 2.7183, x is the chosen value which is equal to 2, Λ is raise to power, ! is factorial sign
p(x=2) =( 3² x 2.7183⁻³) ÷ 2! = 0.22
Answer:
9
Step-by-step explanation:
4+5=9
Say, for example, you have an improper fraction (it usually is if you're trying to convert to a mixed number) like: 55/7
You would take the highest number that is divisible by the denominator, which in this case is 7 (7x7=49; 7x8 would be 56 and we don't want that)
You subtract the number you got (49) from the original numerator (55).
That will give you 6.
Now, you put the whole number (7) before the fraction (6/7)
Answer:
The two column proof can be presented as follows;
Statement 
Reason
1. RUST is a rectangle Given
2. RU = ST ; UT = RS Definition of a rectangle
3. ∠STU and ∠SRU are right angles Definition of a rectangle
4. ΔURS ≅ ΔSTU By SAS rule of congruency
5. ∠USR = ∠SUT By CPCTC
Step-by-step explanation:
Given that the side RU, the angle ∠SRU and the side RS of triangle ΔURS are congruent to the side ST the angle ∠STU and the side UT of triangle ΔSTU, then ΔURS is congruent to ΔSTU, by the Side-Angle-Side (SAS) rule of congruency
Therefore, we have that ∠USR ≅ ∠SUT and therefore, it can be shown that ∠USR = ∠SUT using the Congruent Parts of Congruent Triangle are Congruent (CPCTC) postulate.
Answer:
C. Associative Property
Step-by-step explanation:
The associative property of addition states that changing the grouping of the addends does not change the sum.
(-7+3)= -4
-4+9= 5
(3+9)= 12
-7+12=5
