A person invested $150 in an account growing at a rate allowing the
money to double every 13 years. How much money would be in the
account after 22 years, to the nearest dollar?
Answer:y=485
y=a(2)^t/d
a=150 d=13 t=22
Step-by-step explanation: y=150(2) 22/13
y=484.759843209
y=485
The rate of the interest on the account is 5.48%. Then the amount of money after 22 years is $485.10.
What is compound interest?Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.
A person invested $150 in an account growing at a rate allowing the money to double every 13 years.
Then the rate will be
[tex]\begin{aligned} 300 &= 150 (1 + r)^{13}\\\\13 \log (1 + r) &= \log 2\\\\\log (1 + r) &= 0.023156\\\\1 + r &= 1.054766\\\\r &= 0.054766 \approx 0.0548 \end{aligned}[/tex]
Then the amount of money after 22 years will be
[tex]\rm Amount = 150(1 + 0.0548)^{22}\\\\Amount = 150 \times 3.234\\\\Amount = \$ \ 485.1[/tex]

Question 2 What is the correct order of operations to complete a math problem?
The height of sunflowers is Normally distributed with mean 50 inches and standard deviation 8 inches. Use your calculator's statistical functions to find the percent of all sunflowers that are between 35 and 40 inches tall. Be sure to write your answer as a percent, but don't put the percent symbol. Once in percent form, round to 2 places after the decimal.
Answer:
7.57
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
The height of sunflowers is Normally distributed with mean 50 inches and standard deviation 8 inches.
This means that [tex]\mu = 50, \sigma = 8[/tex]
Percent of all sunflowers that are between 35 and 40 inches tall.
As a proportion, this is the pvalue of Z when X = 40 subtracted by the pvalue of Z when X = 35. So
X = 40
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{40 - 50}{8}[/tex]
[tex]Z = -1.25[/tex]
[tex]Z = -1.25[/tex] has a pvalue of 0.1057
X = 35
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{35 - 50}{8}[/tex]
[tex]Z = -1.88[/tex]
[tex]Z = -1.88[/tex] has a pvalue of 0.03
0.1057 - 0.03 = 0.0757
As percent: 0.0757*100% = 7.57%

An electronic office product contains 5100 electronic components. Assume that the probability that each component operates without failure during the useful life of the product is 0.999, and assume that the components fail independently. Approximate the probability that 2 or more of the original 5100 components fail during the useful life of the product. Use normal approximation. Round your answer to 3 decimal places.
Answer:
The probability that 2 or more of the original 5,100 components may fail during the useful life of the product is:
= 0.001
Step-by-step explanation:
Probability of operating without failure = 0.999
The probability of failed component = 0.001 (1 - 0.999)
The number of components of the electronic office product = 5,100
The number of components that may fail, given the above successful operation = 5.1 (0.001 * 5,100).
Therefore, the probability that 2 or more of the original 5,100 components may fail during the useful life of the product = 0.001
Probability of component failure is the likelihood that a component fails during the useful life of the product. It is expressed as the number of likely failed components divided by the total number of components. This result can be left in decimal form or expressed as a percentage.
Following are the solution to the given expression:
[tex]\to \text{p = p (failure)} = 1 -0.999 = 0.001 \\\\[/tex]
We employ the binomial approximation of the normal distribution with mean.
[tex]\to \mu = np = 5100(0.001) = 5.1 \\\\ \to \text{standard deviation} \ (\sigma) = \sqrt{np(1-P)}[/tex]
[tex]= \sqrt{5100(0.001)(1-0.001)} \\\\ = \sqrt{5.1 \times (0.999)} \\\\= \sqrt{5.0949 } \\\\= 2.2572[/tex]
It require [tex]p(x\geq 2)[/tex] but we find [tex]p(x \geq 1.5)[/tex], because of [tex]0.5[/tex] correction.
Here
[tex]\to z = \frac{X-\mu}{\sigma }[/tex]
[tex]=\frac{1.5-5.1}{2.2572} \\\\ =\frac{-3.6}{2.2572} \\\\ = -1.59 \\\\[/tex]
Calculating the required probability:
[tex]\to p(z \geq -1.59)[/tex]
[tex]=1+ p(z< 1.59) \\\\= 1+ 0.9440826[/tex] , by standard normal table
[tex]= 1.9440826 \approx 1.944[/tex]

Rimo spends £588 on a plane ticket and $130 on airport tax. Using £1 = $1.34, what percentage of the total cost does Rimo spend on airport tax?
Give your answer rounded to 1 dp.
PLEASE HURRY I'VE POSTED THREE TIMES THIS QUESTION BUT NO ANSWERS ONLY WATCHERS
Answer:
Percentage = 14.2%
Step-by-step explanation:
Given the following data;
Cost of plane ticket = £588
Airport tax = $130
£1 = $1.34
To find the percentage of the total cost spent on airport tax;
First of all, we would convert the ticket cost in pounds (£) to dollars ($).
Cost of plane ticket = £588 to $ = 588 * 1.34 = $787. 92
Total cost = Cost of plane ticket + Airport tax
Total cost = 787. 92 + 130
Total cost = $917.92
[tex] Percentage \; cost = \frac {130}{917.92} * 100 [/tex]
[tex] Percentage = 0.1416 * 100 [/tex]
Percentage cost = 14.16 to 1 d.p = 14.2%
Therefore, the percentage of the total cost spent on airport tax by Rimo is 14.2 percent.
A real estate agent has 8 master keys to open several new homes. Only 1 master key will open any given house. If 40% of these homes are usually left unlocked, what is the probability that the real estate agent can get into a specific home if the agent selects 3 master keys at random before leaving the office?
Answer:
Step-by-step explanation:
Suppose F represents the value that a room is unlocked.
Then, we can assume that the probability of unlocked homes is:
P(unlocked homes) = P(U)
P(unlocked homes) = 40%
P(unlocked homes) = 0.40
Also, let us represent the value of the locked room with G.
P(locked homes) = P(G)
P(locked homes) = (1 - 0.40)
P(locked homes) = 0.60
Let the probability of selecting a correct key be P(S)
It implies that for the agent to use 3 keys, we have a combination of [tex]^8C_3[/tex] possible ways for the set of keys.
Now; since only one will open the house, then:
P(select correct key) = P(S)
[tex]P(S) = \dfrac{ (^1_1) (^7_2) }{ ^8_3 }[/tex]
[tex]P(S) = \dfrac{21}{56}[/tex]
P(S) = 0.375
Finally, for the real estate agent to have access to specific homes supposing the agent select three master keys at random prior to the time he left his office, Then:
P(F ∪ (G∩S) = P(F) + P(G∩S)
P(F ∪ (G∩S) = P(F) + P(G) × P(S)
P(F ∪ (G∩S) = 0.40 + (0.60×0.375)
P(F ∪ (G∩S) = 0.40 + 0.225
P(F ∪ (G∩S) =0.625

Which is the logarithmic equation log8 64 = a, written in exponential form?
Step-by-step explanation:
log8 64 = a
cut log and base^a
64 = 8^a
8^a = 64
or a = 2
Answer:
[tex]8^a = 64[/tex], which gives [tex]a=2[/tex].
Step-by-step explanation:
When you see [tex]\log_8(64)=a[/tex], think: [tex]a[/tex] is the number such that [tex]8^a = 64[/tex]. Mathematical intuition gives us that [tex]a=2[/tex] immediately, but we can also work this out more methodologically:
[tex]8^a = 64\\(2^3)^a = 2^6\\2^{3a} = 2^6\\3a = 6\\a = 2[/tex]
And this solution suffices.

Step-by-step explanation:
Sum = (n-2)180
=(7-2)180
=(5)180
=900
Answer:
900 degrees
Step-by-step explanation:
The formula for calculating the sum of the interior angles of a regular polygon is : ( n - 2) × 180°. when n is number of sides.
Sum of angles = ( n-2) × 180
Sum of angles = (7-2) × 180
Sum of angles = 5 × 180
Sum of angles = 900 degrees

What is the Ratio?The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Here, remaining pizza = 1 / 3
Rachel eats 1 /2 of the remaining pizza so,
= 1 / 2 * 1 / 3
= 1 / 6

Step-by-step explanation:
There are no given values, therefore we can't determine a definite answer. However, we are able to simplify the expression.
As we all know that any variable or number to the power of 0 is equal to 1. This means that [tex]y^0 = 1[/tex].
We also know that a negative power can bring the variable down and make it a fraction. This means that [tex]z^-^2=\frac{1}{z^2}[/tex]
