Answer:
Attached linear graph
Step-by-step explanation:
The value of e is a mathematical constant of 2.72 approximately. We can consider this a constant as 1. Therefore this is a straight line with a gradient/slope of -2 and a y-intercept of:
and x intercept of:
We can use population formula
we are given
interest rate is 1.5% per day
so,
now, we can plug values
we are given
P(t)=2Po
we can plug it
we can solve for t
so,
number of days is 46.5..........Answer
The correct answer is option C which is 3 sets of 2 negative tiles.
<h3>What is multiplication?</h3>
Multiplication is the process of determining the product of two or more numbers in mathematics.
We have the product of 3 and -2. We can represent this as 3 is equivalent to -2 negative tiles.
When we add -2 three times -2 - 2 -2 = -6 we will get -6 that is 3 sets of 2 negative tiles.
So when we multiply it by 3, we end with 3 sets of 2 negative tiles. This is because the order of the factors does not change the product.
Therefore the correct answer is option C which is 3 sets of 2 negative tiles.

Answer:
18.0167≤x≤21.9833
Step-by-step explanation:
Given the following
sample size n = 10
standard deviation s = 3.2
Sample mean = 20
z-score at 95% = 1.96
Confidence Interval = x ± z×s/√n
Confidence Interval = 20 ± 1.96×3.2/√10
Confidence Interval = 20 ± (1.96×3.2/3.16)
Confidence Interval = 20 ± (1.96×1.0119)
Confidence Interval = 20 ± 1.9833
CI = {20-1.9833, 20+1.9833}
CI = {18.0167, 21.9833}
Hence the required confidence interval is 18.0167≤x≤21.9833
Answer: 5
Step-by-step explanation:
25-15= 10
half of 10 is 5
so she originally had 5
