Suppose you are depositing an amount today in an account that earns 5% interest, compounded annually. If your goal is to have $5000 in the account at the end of six years, how much must you deposit in the account today?
Answer:
If you walk into a bank and open up a savings account you will earn interest ... include the amount of money deposited called the principal, the annual interest rate ...
Answer:
3731.08
Step-by-step explanation:
let x= the present value (or principle)
[tex]5000=x(1.05)^6\\\frac{5000}{1.05^6}=x\\x=3731.076983[/tex]
Kendall is starting a new small business and working everyday to make it a success. She earned $952 in 7 days. Assume she will continue to earn money as the same rate and write this rate as a fraction with 30 in the denominator.
Answer:
$4080 / 30days
Step-by-step explanation:
In 7 days, Kendall earns $952
In 1 day, she will earn $952 ÷ 7 = $136
Therefore, the rate (r) at which she earns is $136/day. i.e
r = $136/day ---------------(i)
To write the rate as a fraction with 30 in the denominator, we multiply both the numerator and denominator of equation (i) by 30 as follows;
r = $(136x30) / 30 day
r = $4080/30days

The graph of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?
Answer:
x = -8, x =0 and x =6
Step-by-step explanation:
f(x) = 0 means when it crosses the x axis or when y = 0
There are 3 places when it crosses the x axis
x = -8, x =0 and x =6
Line p passes through points (5,-4) and (2,7). What is the slope of a line that is perpendicular to line p
Answer:
3/11
Step-by-step explanation:
First find the slope of the line
m = (y2-y1)/(x2-x1)
= ( 7 - -4)/(2 - 5)
= (7+4)/(2-5)
=11/ -3
We want a line that is perpendicular, so it is the negative reciprocal
-1 / ( -11/3)
+3/11
A line that is perpendicular will have a slope that is 3/11
A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of no more than centimeters. The factory believes that the length of the bolts exceeds this value and measures the length of bolts. The sample mean bolt length was centimeters. The population standard deviation is known to be centimeters.
What is the test statistic z?What is the p-value?Does sufficient evidence exist that the length of bolts is actually greater than the mean value at a significance level of α=0.1?
Answer:
There is sufficient evidence. A further explanation is provided below.
Step-by-step explanation:
According to the question,
The alternative as well as null hypothesis will be:
[tex]H_0:\mu = 16[/tex]
[tex]H_a:\mu>16[/tex]
The test statistics will be:
⇒ [tex]z = \frac{\frac{\bar x - \mu}{\sigma} }{\sqrt{n} }[/tex]
By putting the values, we get
⇒ [tex]=\frac{\frac{16.06-16}{0.24} }{\sqrt{96} }[/tex]
⇒ [tex]=\frac{\frac{0.06}{0.24} }{\sqrt{96} }[/tex]
⇒ [tex]=2.45[/tex]
Or,
The p-value will be:
= 0.0071
i.e.,
⇒ [tex]p-value< \alpha[/tex]
Thus the above is the correct answer.

the sum of two numbers is 37 and the greater number is 5 less than twice the Lesser number find the positive intergers
Answer:
x = 14
y = 23
Step-by-step explanation:
x = first number
y = second and greater number
x + y = 37 ⇒ y = 37 - x
y + 5 = 2x
Substitution:
(37 - x) + 5 = 2x
42 - x = 2x
3x = 42
x = 14
y = 37 - (14)
y = 23
the lengths of two sides of a triangle are 2x-5 and x+3. If the perimeter of the triangle is 4x-1, what is the length of the third side in terms of x?
Answer:
[tex]x-9[/tex]
Step-by-step explanation:
[tex]side_1=2x+5\\side_2=x+3\\side_3=\phi\\perimeter=\displaystyle\sum_{i=1}^3side_i=(2x+5)+(x+3)+\phi=4x-1\\\phi=4x-1-x-3-5-2x=x-9[/tex]
The length of the third side in terms of x is x+1.
What is the perimeter of the triangle?The perimeter of a triangle is the sum of all its three sides.
We can work out the perimeter using the following formula:
The perimeter of a triangle is = sum of all three sides.
The length of the third side in terms of x is given by;
[tex]\rm Perimeter \ of \ triangle = Side \ a + Side \ b + Side \ c[/tex]
Substitute all the values in the formula
[tex]\rm Perimeter \ of \ triangle = Side \ a + Side \ b + Side \ c\\\\4x-1=2x-5+x+3+Side \ c\\\\4x-1=3x-2+Side \ c\\\\Side \ c=4x-3x-1+2\\\\Side \ c=x+1[/tex]
Hence, the length of the third side in terms of x is x+1.

research questions and types of data where one would expect the data to be skewed?
Answer:
Explained below
Step-by-step explanation:
A) A skewed distribution in a dataset is when the median is not equal to the mean in such a manner that the bell curve is tilted to the left or right.
B) If in a data set, there are outliers which are extremely large or extremely small in comparison to other values in that same dataset, then we can say that such a curve will be pulled towards the outlier and thus the distribution is skewed.
Also, if the curve is inclined to the left, it means there are few extreme values to the left and is is negatively skewed.
Similarly, if the curve is inclined to the right, it means there are few extreme values to the right and is positively skewed.
C) Example of a research question is;
If in a developed country where the poverty level is about 0%, if we collect the data of income of the households, we will discover majority of people with average income and very few people with extreme high levels of income. This condition means the data to is positively skewed.

The number line (d) represents the values of x that makes -3x + 1 < 7 to be true
How to determine the number line?The inequality is given as:
-3x + 1 < 7
Subtract 1 from both sides
-3x < 6
Divide both sides by -3
x > -2
This means that the number line must show an inequality that is greater than -2
From the list of options, the number line that represents x > -2 is (d)
Hence, the number line (d) represents the values of x that makes -3x + 1 < 7 to be true

Angel signed up for a streaming music service
that costs $11 per month. The service allows
Angel to listen to unlimited music, but if he
wants to download songs for offline listening, the
service charges $0.50 per song. How much total
money would Angel have to pay in a month in
which he downloaded 25 songs? How much
would he have to pay if he downloaded s songs?
Answer:
Cost for 25 songs: $23.50
Cost for s songs: .50(s) + 11
Step-by-step explanation:
To solve this problem, we can make an equation in slope-intercept form:
y = mx + b
y represents the total amount of $.
m represents the cost of each song downloaded, or $.50
x represents the number of songs, or 's'
b represents the $11, or the constant.
We have the equation:
y = .50(x) + 11
If Angel downloaded 25 songs, we have the equation:
y = .50(25) + 11
We get y = $23.50

Using the following image, solve for FE
Answer:
FE = 3
Step-by-step explanation:
FE + ED = 11.
(2x - 17) + (x-2) = 11
Combine like terms, and you'll get:
3x -19 = 11
3x = 11+19 = 30
x = 10
FE = 2x - 17
= 2(10) - 17
= 20 - 17

Step-by-step explanation:
When you look at the bar graph at the top, you will see that there are 5 of 1 1/4.
If you multiply 5 by 5/4 (which is 1 1/4 converted to an improper fraction), you get 25/4. To convert that to a mixed number, divide 25 by 4 and put the remainder over 4. The final answer should be 6 1/4.
For the X's, just count how many of each number is in the graph above. For example, there should be 2 X's over 1, 5 X's over 1 1/4, 2 X's over 1 1/2, and 2 X's over 1 3/4.
