Answer:
Arithmetic sequence
Step-by-step explanation:
-We notice that the difference between the number of favors already given out between any two consecutive number of party guests has an additive increment.
-This increment is called the Common Difference and has a value of 3.
-The number of tickets available is 50.
Hence, the number of tickets already given out can be calculated using the formula:
Hence, this is an Arithmetic Sequence.
Answer:
$11.25
Step-by-step explanation:
1.5×7.5=11.25
Answer:
28 ft
Step-by-step explanation:
Answer:
0.02275
Step-by-step explanation:
We use this z score formula to solve for this question
z-score is is z = (x-μ)/σ/√n
where x is the raw score
μ is the population mean
σ is the population standard deviation
From the above question,
x = 77
μ = 75
σ = 7
number of samples = 49
Hence, the z score = 77 - 75/ (7/√49)
= 2/(7/7)
= 2/1
= 2
Hence, the z score = 2
Using the z table to find probability
P(x<77) = 0.97725
P(x>77) = 1 - P(x<77)
= 1 - 0.97725
= 0.02275
Therefore, the probability that the same mean will be larger than 77 years
is 0.02275
ANSWER
Yes it is very true
<u>EXPLANATION</u>
If the two equations intersect at 
then this point must satisfy the two equations.
We substitute in to erquation (1)
We now substitute in to erquation (2) also
Since the point satisfy all the two equations, it is true that they intersect at
