Answer:
b = 363
Step-by-step explanation:
Sum of a geometric Progression is expressed as attached.
a = 3 = the first term
r = 3 = the common ratio
n = 5 = number of term
Sum of GP = a(r^n - 1)/ r-1
= 3(3^5 - 1)/ 3-1
= 3(234 - 1) / 2
= 3(242) / 2
= 726/2
= 363
Answer:
It represents a proportional relationship, since it has the same format as the equation of a line.
Step-by-step explanation:
Equation of a line:
Has the following format:
y = ax + b
It represents a proportional relationship.
In this question:
y = 1.5x + 10
Has the same format of the equation of a line. This means that it represents a proportion relationship.
Answer: $9
Step-by-step explanation: If Wendy wants to own a total of 12 necklaces, that means Wendy wants to buy 9 more necklaces, since she already owns 3. We know that each necklace is a dollar.
So if Wendy buys 9 necklaces for a dollar each, then the total price will be $9 for Wendy to own a total of 12 necklaces.
( 9 x 1 = 9)
Answer: 0.4402
Step-by-step explanation:
Given : The proportion of the registered voters in a country are Republican = P=0.50
Sample space = 36
The test statistic for proportion :-
For p= 0.477
For p= 0.58
Now, the probability that the proportion of freshmen in the sample is between 0.477 and 0.58 (by using the standard normal distribution table):-
Hence, the probability that the proportion of freshmen in the sample is between 0.477 and 0.580 = 0.4402
( 3x 1/10) + ( 6x 1/100) +( 8x 1/000
