Please look at the following numbers listed above and determine a relationship:
Are they exponential or linear? Why?
Answer:
neither exponential nor linear
Step-by-step explanation:
A linear relationship will show a common difference between adjacent value. Here, the first differences between the first three values are 5 and 33. They are not the same, so the relation is not linear.
__
An exponential relationship will show first differences that are continuously increasing or decreasing by increasing or decreasing amounts (respectively).
As we showed, the difference between May 28 and May 27 is 33. This is more than the previous difference. However, the difference between May 30 and May 31 is only 28, which is less than a previous difference.
The relation is not exponential.
__
A graph points up the non-linearity of the relation.

Which of the following functions has:
Domain: LaTeX: \left(-\infty,\:\infty\right)( − ∞ , ∞ )
Range: [LaTeX: 0,\:\infty0 , ∞ )
Answer:
We can't see the functions. We also can read the domain or the range. Personal suggestion is to write the domain and range (-infity, 0) but substitute in what applies to your situation.

In a cartons of bulbs, 90% contain no defective bulbs, 5% contain one defective bulb, 3% contain two defective bulbs, and 2% contain three defective bulbs. Find the mean and standard deviation for the number of defective bulbs.
Answer:
Mean, E(x) = 0.17
Variance, V(x) = 0.12
Step-by-step explanation:
90% contains no defective bulbs, P(X=0) = 0.9
5% contain one defective bulbs, P(X=1) = 0.05
3% contain two defective bulbs, P(X=2) = 0.03
2% contain three defective bulbs, P(X=3) = 0.02
The mean for the number of defective bulbs:
[tex]E(X) = \sum XP(X)\\E(X) = (0*0.9) + (1*0.05) + (2*0.03) + (3* 0.02)\\E(X) = 0 + 0.05 + 0.06 + 0.06\\E(X) = 0.17[/tex]
Variance for the defective bulbs:
[tex]V(x) = (\sum x^{2}P(x) ) - \mu^2[/tex]
[tex]\sum x^{2}P(x) = (0^2*0.9) + (1^2*0.05) + (2^2*0.03) + (3^2* 0.02)\\\sum x^{2}P(x) = 0.05 + 0.12 + 0.12\\\sum x^{2}P(x) = 0.29[/tex]
V(x) = 0.29 - 0.17
V(x) = 0.12

Paul creates a CD by mixing together
songs that are either 3 minutes or
4 minutes long. His CD has 22 songs
and is 78 minutes long. How many
three-minute and how many four-minute
songs did he use?
Answer:
Paul created 10 three minutes songs and 12 four minutes songs.
Step-by-step explanation:
The song he created on his CD is either 3 minutes long or 4 minutes long.
His CD has 22 songs and is 78 minutes. The number of 3 minutes and 4 minutes song can be calculated below.
Let
a = number of 3 minutes song
b = number of 4 minutes song
number of song = 22
a + b = 22............(i)
3a + 4b = 78.........(ii)
Make a subject of the formula in equation (i)
a = 22 - b
Insert the value of a in equation (ii)
3(22 - b) + 4b = 78
66 - 3b + 4b = 78
b = 78 - 66
b = 12
insert the value of b in equation (i)
a + b = 22
a + 12 = 22
a = 22 - 12
a = 10
Paul created 10 three minutes songs and 12 four minutes songs.

Answer:
12 square units.
Step-by-step explanation:
We must find the area of each shape and add together. The area of a triangle is 1/2 base times height. The smaller triangles area is 2 and the larger triangle's area is 6. The area of the square is 4... so when all added together, we have 12.

A snail creeks up a plank 8 cm a day and slides back down 15 millimeters each night. Write a numerical pattern showing the number of millimeters where the snail changes direction. On which day would the snail have moved 275 millimeters from its starting point?
Answer: The 5th day
Step-by-step explanation:
Total daily movement :
Upward movement = 8cm
Downward movement = 15mm
Converting the upward movement to millimeters ; 1 centimeter = 10 millimeters
Upward movement = 8 × 10 = 80 millimeters
Daily movement can beodelled using the equation :
Distance = (80mm - 15mm)h
Where h is the number of days
Movement per day = 65mm
To move a distance of 275mm from its starting position:
Number of days = 275mm/ 65mm
Number of days = 4.23
Therefore the snail would have moved 275 millimeters from its starting point on the 5th day
Find the volume of this rectangular prism.
Answer:
200 units³
Step-by-step explanation:
The formula for the volume of a rectangular prism is:
V = lwh
where l is the length, w is the width, and h is the height
Substitute with the given values:
V = lwh
V = (10)(4)(5)
Multiply:
V = (10)(4)(5)
V = (40)(5)
V = 200
Therefore, the volume of the rectangular prism is 200 cubic units.
Determine the answer to (−3) + (−5) and explain the steps using a number line
Answer:
-8
Step-by-step explanation:
When adding a negative number on a number line, we move to the left. This is because adding a negative number is the same as subtracting. If we start at -3 and move 5 to the left, we will end at -8.
The figure shows two regular pentagons. What is the perimeter of the larger pentagon?
A. 5n
B. 10n
C. 15n
D. 60n
Answer:
As shown in picture,
perimeter of inside pentagon: p1 = n + n + n + n + n = 5n
ratio between inside pentagon and outside pentagon: r = 6/(6 + 6) = 1/2
=> perimeter of outside pentagon: p2 = 2 x p1 = 2 x 5n = 10n
=> Option B is correct

Answer:
1. The rocket was launched from a height of 180 feet.
=> Valid because at time = 0 sec, height = 180 feet (as shown in table)
2.The maximum height of the rocket occurred 3 seconds after launch.
=> Valid because at time = 3 sec, height = 324 feet (greatest value in second row of table).
3.The rocket was in the air approximately 6 sec before hitting ground.
=> Not valid because the time in table in about 7 sec (from 0 to 7), but all of the heights are greater than 0 (the rocket has not hit the ground yet).
4. The rocket was above 300 feet for approximately 2 seconds.
=> Valid because from sec 2 to sec 4: the height is greater than 300 (308, 324, and 308)
=> Option 3 is not valid.
Hope this helps!

A rectangle with sides 4 cm and 6 cm has the same diagonal as a square.
What is the length of the side of the square.
Give your answer as a surd.
Answer:
not sure but this info might help you.
Step-by-step explanation:
the diagonal in the rectangle splits it into two right angled triangles, hence the hypotenuse is the diagonal.
once you find the measurement, we all know that a square has all sides equal and the diagonal splits it into 2 equilateral triangles. so, the side of the square =the diagonal's measurement.

Natalie buys a new car. In the first month, the odometer on the car records 800 miles. From past experience, she expects to drive 900 miles per month.
Select all the functions that can be used to find the number of miles, f(n), recorded on the odometer after n months.
Answer:
[tex]\begin{aligned}\bullet\ &f(1)=800;f(n)=f(n-1)+900, \text{for $n\ge 2$}\\ \bullet\ & f(n)=900n-100\end{aligned}[/tex]
Step-by-step explanation:
See attachment for the figure.
Using arithmetic sequence with a first term of 800 and a common difference of 900. The general form for such a sequence is given by,
an = a1 +d(n -1)
an = 800 +900(n -1) = 900n -100
If n is the function, this can be written as,
f(n) = 900n -100
When considered as a recursive relation, we find the first term is still 800:
f(1) = 800
and that each term is 900 more than the previous one:
f(n) = f(n-1) +900 . . . . for n ≥ 2
You need to consider that huge numbers of the different answer decisions are debasements of either of these structures, so you should look at them cautiously.

Quincy has $6,000 in a savings account that earns 4% interest, compounded annually.
To the nearest cent, how much interest will he earn in 5 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer:
A = $ 7,299.92
A = P + I where
P (principal) = $ 6,000.00
I (interest) = $ 1,299.92
Step-by-step explanation:
A = P(1 + r/n)^nt
Where:
A = Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
R = Annual Nominal Interest Rate in percent
r = Annual Nominal Interest Rate as a decimal
r = R/100
t = Time Involved in years, 0.5 years is calculated as 6 months, etc.
n = number of compounding periods per unit t; at the END of each period

5m- 3 = 4m +30
can you please help me with this problem
Answer:
m=33
Step-by-step explanation:
To solve this, we need to get the variable, m, by itself. Perform the opposite of what is being done to the equation. Keep in mind everything done to one side, must be done to the other.
5m-3=4m+30
3 is being subtracted from 5m. The opposite of subtraction is addition, so add 3 to both sides.
5m-3+3=4m+30+3
5m=4m+33
4m is being added on to 33. The opposite of addition is subtraction, so subtract 4m from both sides.
5m-4m=4m-4m+33
5m-4m=33
m=33

What is histogram?A histogram is an approximate representation of the distribution of numerical data. A histogram is a graph that shows the frequency of numerical data using rectangles. The height of a rectangle (the vertical axis) represents the distribution frequency of a variable (the amount, or how often that variable appears).
here, we have,
We are given a the 30 data points which represent the best lifetime baseball batting averages of all time, arranged in order from lowest to highest.
As we know that we could obtain a frequency table from the following set of data points and histogram is a good way to represent the frequency data. ( i.e. a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins ).
Hence, the given statement,
A frequency table for these data can best be graphically displayed as a bar graph. That is, it should not be displayed as a histogram is a FALSE STATEMENT.
