Write a recursive and explicit formula for each option.
Save a nickel on the first day of the month and then double the amount each day for a month
=> a1 =0.05
=> a2 = a1* 2 = 0.05*2
=> a3 = a2*2 = a1* 2*2
..............................................
=>recursive an = 
=> explicit an = 0.05*
Start their savings by saving $10 on the first day and then $10 each day of the month
=> a1 = 10
=> a2 = a1 + 10 = 20
=> a3 = a2 +10 = 20 +10 =30
........................................................
=> recursive an = 
=> explicit an = 10 + 10( n-1)
Hope it will find you well.
Answer:
1).false 2). false 3).true 4). true
Step-by-step explanation:
1).All whole numbers are integers, so s...” That's right! All whole numbers are integers, so since 0 is a whole number, 0 is also an integer.
3).. Integers include all whole numbers and their negative counter part e.g. … -4, -3, -2, -1, 0,1, 2, 3, 4,… Where a and b are both integers. is a rational number but not an integer. 4). All integers are rational number. Since we can rewrite an integer into a fractional form by diving it by 1. For example, 4=41 4 = 4 1 . But not all rational numbers are integer.
Answer:
91.63 cm is the interior length of the bassinet to ensure that 99 percent of newborn babies will fit, with a safety margin of 15 cm on each end of the bassinet.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 50 cm
Standard Deviation, σ = 5 cm
We are given that the distribution of length of a newborn baby is a bell shaped distribution that is a normal distribution.
Formula:
P(X<x) = 0.99
We have to find the value of x such that the probability is 0.99
P(X < x)
Calculation the value from standard normal table, we have,
Thus, 99% of newborn babies will have a length of 61.63 cm or less.
There is a safety margin of 15 cm on each end of the bassinet
Length of bassinet =
Answer:
no solution
Step-by-step explanation:
X/3+2=x/3
Subtract x/3 from each side
X/3-x/3+2=x/3-x/3
2 = 0
This is never true so there is no solution
