Answer:
800(1 + r)³ + 300(1 + r)² + 625(1 + r)
Step-by-step explanation:
At the beginning of the first year $800 is deposited.
At the end of the first year the amount of money in account = $800 × growth factor = 800(1 + r)
At the beginning of the second year, $300 is deposited, the money in account = 800(1 + r) + 300
At the end of the second year the amount of money in account is multiplied by growth factor. = [800(1 + r) + 300] × 1 + r = 800(1 + r)² + 300(1 + r)
At the beginning of the third year, $625 is deposited, the money in account = 800(1 + r)² + 300(1 + r) + 625
At the end of third year the money = [800(1 + r)² + 300(1 + r) + 625] × 1 + r = 800(1 + r)³ + 300(1 + r)² + 625(1 + r)

Assume the readings on thermometers are normally distributed with a mean of 0 degrees C and a standard deviation of 1.00 degress C. Find the probability that a randomly selected thermometer reads between -2.21 and -1.52 and draw a switch then find the probability.
The standard normal distribution has a cumulative distribution function (probability that the random variable, in this case the temperature, is less than a given number) well-known as erf, and the probability of [tex]T\in[-2.21,-1.52][/tex] is [tex]erf(-1.52)-erf(-2.21)\approx 0.0298109[/tex] (found using WolframAlpha)

a 175,000 loan compounded monthly at 3.2% for 19 years. how much intrest was earned
Answer:
Interest earned = $146,196.75
Step-by-step explanation:
A = $175,000
r = 3.2% = 0.032
n = 19
m = 12
FV = A*(1+i/m)^nm
FV = 175,000*(1+0.032/12)^19*12
FV = 175,000*(1+0.002667)^228
FV = 175,000*(1.002667)^228
FV = 175,000*1.83541
FV = $321196.75
Interest earned = $321,196.75 - $175,000
Interest earned = $146,196.75

Jonny is buying a new pair of shoes. If the shoes are normally $25.00 and are on sale for 20% off, how much will he pay for the shoes before tax?
Answer:
$20
Step-by-step explanation:
First, we need to find 20% of $25. You can do this by multiplying $25 by 0.2
After multiplying , you get $5. So 20% of 25 is 5.
Now, we subtract because the shoes are 20% off
25 - 5 = $20
I hope this helped, please mark Brainliest, thank you!

A goat is tethered to a rope that is 3.65 meters long. What is the maximum area of grass that the goat can graze on?
Answer:
3.65 meters
Step-by-step explanation:
If the rope is 3.65 meters long, then the goat can only go as far as the rope is long. That's unless the goat eats the rope.
The maximum area that a goat can graze on will be the area of a circle where the center of the circle will be one end of the rope as shown in the attached diagram.
What is the area of a circle?The area of a circle with radius r is πr².
Radius of the circle= length of the rope = 3.65m
So, area of the circle = [tex]\pi r^{2}[/tex]
Area of the circle = [tex]\pi 3.65^{2}[/tex]
Area of the circle = 41.85m².
Therefore, the maximum area of grass that the goat can graze on is 41.85 m²

A woman wishes to enclose a rectangular garden with fencing, using the side of her garage as one side of the rectangle. A neighbor gave her 2727 feet of fencing, and she wants the length of the garden along the garage to be 66 feet more than the width. What are the dimensions of the garden?
Answer:
Length = [tex]13\ \text{ft}[/tex]
Width = [tex]7\ \text{ft}[/tex]
Step-by-step explanation:
Let
Breadth of the garden = x
According to the question length of the garden = 6+x
Fencing given for the rectangular garden = 27 ft
Perimeter of the garden is given by
[tex]6+x+x+x=27\\\Rightarrow 6+3x=27\\\Rightarrow x=\dfrac{27-6}{3}\\\Rightarrow x=7\ \text{ft}[/tex]
Here the garden's length will be along the garage so fencing will not done there. So length will be added only once in the perimiter.
The length of the garden is [tex]6+7 = 13\ \text{ft}[/tex] and the width is [tex]7\ \text{ft}[/tex].

According to data obtained from the National Weather Service 187 of the 368 people killed by lightning were men. Assume that this trend holds for the future. What is the probability that a person killed by lightning is a woman
Answer:
0.4919
Step-by-step explanation:
From the given data:
187 of the 368 people killed by lightning were men.
i.e
Number of men = 187
Total number of people killed = 368
The objective is to determine the probability that the person killed by lightning is a woman.
The number of women = 368 - 187
The number of women = 181
The probability that the person killed by lightning is a woman = 181/368
= 0.4919
A study of the time spent shopping at a supermarket is for a basket with 20 specific items showed an approximately a uniform distribution between 20 minutes and 40 minutes. What is the probability that the shopping time will be:
Answer:
The probability that the shopping time will be between 25 and 30 minutes is 0.25.
Step-by-step explanation:
The question is:
What is the probability that the shopping time will be between 25 and 30 minutes?
Solution:
Let X represent the time spent shopping at a supermarket for a basket with 20 specific items.
It is provided that X follows Uniform (20, 40).
Compute the probability that the shopping time will be between 25 and 30 minutes as follows:
[tex]P(25<X<30)=\int\limits^{30}_{25} {\frac{1}{40-20}} \, dx[/tex]
[tex]=\int\limits^{30}_{25} {\frac{1}{20}} \, dx \\\\=\frac{1}{20}\times [x]^{30}_{25}\\\\=\frac{30-25}{20}\\\\=0.25[/tex]
Thus, the probability that the shopping time will be between 25 and 30 minutes is 0.25.

what are the property for each equation
Answer:
associative, distributive, commutative
Step-by-step explanation:
Commutative is something just flipped around so the 3rd equation would be commutative. Associative is something with the same numbers but asked in a different way so 1st would be associative. Distributive is breaking the equation down and apart to make it easier to complete so the 2nd would be distributive.

Answer:
y = 1/2x + 8
Step-by-step explanation:
The 8 is where the line passes through the y-coordinate, and the 1/2x is the slope of the line. The 8 is positive because the line passes through +8 and not -8.
One number is selected from the set {1, 2, 3, 4, 5, 6, 7, 8, 9}. Find the probability the selected number is less than 7, given that it is less than 8.
Give your answer as a decimal rounded to 4 decimal places.
====================================================
Explanation:
We're told that "given that it is less than 8", so we only focus on these values {1,2,3,4,5,6,7}. There are B = 7 items in this set.
Of those, the set {1,2,3,4,5,6} are less than 7. There are A = 6 items in this set.
The probability we're after is A/B = 6/7 = 0.8571
Answer:
I just got this question in my book, and i already solved it. so just saying that i now the answer, it is 0.8571

Complete Question
The complete question is shown on the first uploaded image
Answer:
a
[tex]P(0.51 < \^ p < 0.61 ) = 0.2587 [/tex]
b
[tex]P(\^ p > 0.71 ) = 0.15165[/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is [tex]p = 0.64[/tex]
The sample size is n = 50
Generally the mean of this sampling distribution is
[tex]\mu_{x} = p = 0.64[/tex]
Generally the standard deviation is mathematically represented as
[tex]\sigma = \sqrt{ \frac{p(1- p )}{n } } [/tex]
=> [tex]\sigma = \sqrt{ \frac{0.64(1- 0.64 )}{ 50} } [/tex]
=> [tex]\sigma = 0.068 [/tex]
Generally the probability that the value of [tex]\^ p[/tex] will be between 0.54 and 0.61 is mathematically represented as
[tex]P(0.51 < \^ p < 0.61 ) = P( \frac{0.5 4 - \mu_{x}}{\sigma } < \frac{\^ p- \mu_{x}}{\sigma } < \frac{0.6 1 - \mu_{x}}{\sigma } )[/tex]
[tex]\frac{\^ p -\mu}{\sigma } = Z (The \ standardized \ value\ of \ \^ p )[/tex]
[tex]P(0.51 < \^ p < 0.61 ) = P( \frac{0.5 4 - 0.64}{0.068 } < Z < \frac{0.6 1 - 0.64}{0.068} )[/tex]
[tex]P(0.51 < \^ p < 0.61 ) = P(-1.470 < Z < -0.4412 )[/tex]
=> [tex]P(0.51 < \^ p < 0.61 ) = P( Z < -0.4412 ) - P(Z < -1.470 ) [/tex]
From the z table the probabilities of ( Z < -0.4412 ) and (Z < -1.912 ) is
[tex]P ( Z < -0.4412 ) = 0.32953 [/tex]
and
[tex]P(Z < -1.470 ) = 0.070781[/tex]
Generally
[tex]P(0.51 < \^ p < 0.61 ) = 0.32953 -0.070781 [/tex]
[tex]P(0.51 < \^ p < 0.61 ) = 0.2587 [/tex]
Generally the probability that the value of [tex]\^ p[/tex] will be greater than 0.71 is mathematically represented as
[tex]P(\^ p > 0.71 ) = P( \frac{\^ p - \mu_{x}}{\sigma} > \frac{0.71 - 0.64 }{ 0.068 } )[/tex]
=> [tex]P(\^ p > 0.71 ) = P( Z > 1.0294 )[/tex]
From the z table the probabilities of ( Z > 1.0294 )
[tex]P( Z > 1.0294 ) = 0.15165[/tex]
So
[tex]P(\^ p > 0.71 ) = 0.15165[/tex]
