Answer:
1100
Step-by-step explanation:
First, we start off by finding 10% which is $100. We divide that by 10 to get $10 which is 10%. Now we need to multiply 10% (which is $10) by 10 which is $100. That gives you this answer
The total amount in the account on the first day of the 11th year is if Charlie deposits $1000 into his investment account. The account grows at a rate of 8% per year is $1880.
What is interest?When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.
Given data:
Charlie deposits, P = $1000 into his investment account.
The account grows at a rate, r = 8% per year.
The time, t = 11 year
Calculate the simple interest as shown below,
[tex]SI = (P\times r\times t) / 100[/tex]
SI = (1000 × 8 × 11) / 100
SI = $880
Calculate the total amount by the formula given below,
Amount = A
[tex]A = P + SI[/tex]
A = 1000 + 880
A = $1880
Therefore, the total amount in the account on the first day of the 11th year is if Charlie deposits $1000 into his investment account. The account grows at a rate of 8% per year is $1880.

x/4 -6 = -8 pls help i really dont understand this one
Answer:
x = -8
Step-by-step explanation:
Given equation,
→ (x/4) - 6 = -8
Now the value of x will be,
→ (x/4) - 6 = -8
→ x/4 = -8 + 6
→ x/4 = -2
→ x = -2 × 4
→ [ x = -8 ]
Hence, the value of x is -8.

Many of the strongest earthquakes in the world take place off the coast of Alaska in the Andreanof Islands or in Prince William Sound. In 1957, a 9.1 magnitude earthquake hit this area. What was the
intensity of that earthquake? (Round your answer to two decimal places.)
cm
Answer:
1,258,925,411.79cm
Step-by-step explanation:
earth quake is measured with the Richter Scale,
R (Magnitue) = log (I / I°)
where I° is the base intensity to the Richter Scale and will be taken as 1
9.1 = log I
10^9.1 = I
thus,
intensity I = 1,258,925,411.79 cm

if the first term in a geometric system is six and the constant multiple is 3÷4 list out the first five terms in the sequence.
The first five terms in the sequence are 6, 4.5, 3.375, 2.53125 and 1.8984375
How to list out the first five terms in the sequence?The first term of the sequence is given as
First term= 6
The constant multiple is given as
constant multiple = 3/4
These parameters can be represented as
a = 6
r = 3/4
The nth term of a geometric sequence is represented as
A(n) = a(r)ⁿ⁻¹
So, we have the following equation
A(n) = 6(3/4)ⁿ⁻¹
For the first term, we have
A(1) = 6
For other terms, we have
A(2) = 6(3/4) = 4.5
A(3) = 6(3/4)² = 3.375
A(4) = 6(3/4)³ = 2.53125
A(5) = 6(3/4)⁴ = 1.8984375
Hence, the other terms are 4.5, 3.375, 2.53125 and 1.8984375

The upper bounds on the probability that Adam sent at least five emails during the time interval is [0, 1].
in math upper bound refers a number that is greater than or equal to any number in a set
Here we have given that, Adam logs in to an email server at time zero. He then spends his time exclusively on writing emails. His friend Brianna also logs in to the server at time 1 (which means 1 hour later) and starts typing emails independently of Adam.
And we need to find the upper bounds on the probability that Adam sent at least five emails during the time interval.
While we looking into the given question, we have identified that Adam Poisson process with a rate λ A/hour and Brianna Poisson process with a rate λ B/hour.
Here let us consider that Y1 and Y2 be the times at which Adam's first and second emails were sent.
Here we know that the Brianna logs in to the server, you are told that Adam has sent exactly one email so far.
So, here the upper limit while logging is 1. So, the lower limit is 0.
Because these is the real life scenario so the negative value is not applicable.
Therefore, the resulting interval is [0, 1].

What is the percentage for the colors of the gumball?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred.
In this situation, there are 4000 balls and 2240 of then are blue while 1760 area red.
The percentage for blue balls will be:
= Number of blue balls / Total balls × 100

e. The expected values of J and K will be equal, and the variability of J will be greater than the variability of K.
The true statement about J and K is - The expected values of J and K will be equal, and the variability of J will be greater than the variability of K.
The correct answer is option (c)
In this question, we have been given that a certain statistic will be used as an unbiased estimator of a parameter.
The sample size of J = 40.
and the sample size of K = 100.
We need to find the true statement about J and K.
By central limit theorem, both J and K will have same means.
An expression for standard deviation is:
s = σ/√n
From the above expression standard deviation is inversely proportional to the sample size n. This means, as the sample size increases, the standard deviation decreases.
Thus, the correct statement is - The expected values of J and K will be equal, and the variability of J will be greater than the variability of K.

If a= (-9 9), find |a|, giving your answer as a surd in its simplest form.
Answer:
The absolute value of a is equal to 3 * √(2), which is the simplest form of the surd.
Step-by-step explanation:
The absolute value of a number is the distance of the number from zero on the number line. To find the absolute value of a complex number, we take the square root of the sum of the squares of the real and imaginary parts.
In this case, the absolute value of a is given by:
|a| = √((-9)^2 + 9^2) = √(81 + 81) = √(162) = √(9 * 18) = 3 * √(2)
Therefore, the absolute value of a is equal to 3 * √(2), which is the simplest form of the surd.
