Answer:the balance after 7 years is $3216
Step-by-step explanation:
A) Initial amount deposited into the account is $2800 This means that the principal,
P = 2800
It was compounded yearly. This means that it was compounded once in a year. So
n = 1
The rate at which the principal was compounded is 4%. So
r = 4/100 = 0.04
It was compounded for 7 years. So
t = 7
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount in the account at the end of t years. Therefore
A = 2800(1 + 0.04/2)^ 1× 7
A = 2800(1 + 0.02)^7
A = 2800(1.02)^7
A = $3216
What is it?
The IQR describes the middle 50% of values when ordered from lowest to highest. To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
How do you find IQR?
<em>Step 1: Put the numbers in order. ...</em>
<em>Step 2: Find the median. ...</em>
<em>Step 3: Place parentheses around the numbers above and below the median. Not necessary statistically, but it makes Q1 and Q3 easier to spot. ...</em>
<em>Step 4: Find Q1 and Q3. ...</em>
<em>Step 5: Subtract Q1 from Q3 to find the interquartile range.</em>
3y = 3 * 9 = 27
4z = 4 * -12 = -48
: -48 + 27 = -21
: -21 + x = 24
: X = 45.
I hope that makes sense.

Step-by-step explanation:
Answer:
55%
Step-by-step explanation:
probability of something happening = p
probability of that thing not happening = 1 - P
45%= 45/100= 0.45
therefore, the probability of snow today = 0.45
therefore,
probability there will be no snow=1 - 0.45 = 0.55
probability there will be no snow= 0.55
convert 0.55 back to percentage= 0.55×100= 55%
probability there will be no snow= 55%
