If a man rode his personal transporter 3/10 mi to the library, then 3/4 mi to class, and then 7/2 mi to his part-time job, then he rode his personal transporter for 4.55 miles.
To determine how far the man rode his personal transporter we use addition.
total miles the man rode = miles to the library + miles to the class + miles to the part-time job
total miles = 3/10 + 3/4 + 7/2
As these fractions have an unlike denominator, we find a common denominator by determining the least common multiple.
As the least common multiple is equal to 20
Therefore,
total miles = 3(2)/10(2) + 3(5)/4(5) +7(10)/2(10)
total miles = 6/20 + 15/20 +70/20
total miles = 6+15+70/20
total miles = 91/20
total miles = 4.55
Hence, the man rode his personal transporter for 4.55 miles.

Step-by-step explanation:
A scientist grows a species of bacteria in a petri dish. Explain why there is a linear correlation coefficient of 0.1 in the plot of Number of Bacteria versus Time.
A. The bacteria have grown at a steady rate and a line fits the data very well.
B. The bacteria have grown at an exponential rate and a line poorly fits the data.
C. The bacteria have grown at an exponential rate and the line fits the data very well.
D. There is a strong negative correlation between number of bacteria and time.
Based on the fact that the correlation coefficient was 0.1 in the plot of Bacteria versus Time, the reason is B. The bacteria have grown at an exponential rate and a line poorly fits the data.
What is the correlation coefficient?The correlation coefficient shows the relationship between two variables. It is between -1 and 1 and figures closer to 0 denote a weak correlation.
In this instance, Bacteria is known to increase exponentially which means that a linear regression model would make a line that poorly fits the data. This would lead to a low correlation coefficient when it should instead be high.

what is the length of the segment ĀB
The length of line segment AB shown in the line graph is is 2 units
With the given line graph it is very obvious that the line segment AB has two point A and B with -4 and -2 as their value
To measure the length we need to subtract the x coordinate of one end point from the another end point
here we will deduct the x coordinate of b point from the x coordinate of A point which is shown below
- 4 - (-2)
and using the simple integer properties we can solve this problem of line graph
- 4 + 2
which comes out to be 2

Write each expression as a single logarithm.
log₆5+log₆x
The expression log₆5+log₆x as a single logarithm is log₆5x.
The logarithm is exponent's inverse function in mathematics. This indicates that the exponent to which a fixed number(say a) at base b, must be raised in order to create a number x, is represented by the logarithm of that number.
For example if 8=2³ can be written in the logarithmic form as
log₂8=3.
The general properties of logarithm for a fixed base are:
logₐa=1logₐx+logₐy=logₐxylogₐx-logₐy=logₐ(x/y)logₐxⁿ=n logₐxlogₓy=(logₐy)/(logₐx)Here the given logarithmic expression is (log₆5+log₆x)
So according to the properties of logarithms we can use the above property "logₐx+logₐy=logₐxy" to simplify the given expression.
Therefore:
log₆5+log₆x
=log₆(5×x)
=log₆5x
Hence written as a single logarithm the expression is log₆5x.

Your friend says that the magnitude of vector (8 , 3) is 4 times that of vector (2 , 3) since 8 is 4 times 2 . Explain why your friend's statement is incorrect.
With the help of the Magnitude formula, we can say that Magnitude of 1st vector is more than the 2nd vector.
A vector is an object that has both magnitude and direction. To find the size of a vector, we need to calculate the length of the vector. Variables such as velocity, distance, force, and momentum are vector variables. But velocity, mass, distance, volume, temperature, etc. is a scalar quantity. A vector has both magnitude and direction, while a scalar has only one magnitude.
The Magnitude of a vector is the length of the vector. The Magnitude value of vector a is represented by ∥a∥.
For a two-dimensional vector a= (a1, a2), the formula for its Magnitude is written below.
By using the Magnitude formula, we can say that Magnitude of 1st vector is more than the 2nd vector.

The value of the expression e⁻⁴ is 0.0183 to four decimal places.
We are given the expression:
e⁻⁴
We need to evaluate the expression to four decimal places.
Now, we know that the value of e is:
e = 2.71828182846
Now, e⁻⁴ can also be written as:
e⁻⁴ = 1 / e⁴
Substituting the value of e, we get that:
1 / e⁴ = 1 / (2.71828182846)⁴
= 1 / 54.5981500331
= 0.0183156389

Answer:
1st question: $-4.5
2nd question: 32
3rd question: -27
Step-by-step explanation:
1st question:
Alan's octopus is $-7 dollars right now. After reloading $50 dollars in, it just means that he put $50 dollars in. We can work it out like this:
-7+50=43 (you can switch the equation around but the sign has to go with it: 50-7)
Now Alan's octopus has $43 in it. It then says that Alan spends $48.5 for a really expensive pencil case. You can calculate it like this:
43-48.5=-4.5 (43-48.5 is the same as 43.0-48.5 and you can work it out on a number line).
This leaves Alan's octopus to only have $-4.5 which means he is in debt again.
2nd question:
I can make it out that it says: Tony adds -18 to +50. Find the results (I hope I saw it right). The equation of it would look like:
-18+50 or you can flip it around but the sign has to go with them like in question one which will look like this: 50-18=32. So the result of Tony's problem is 32.
3rd question:
Patty subtracts +11 from -16. Find the results.
First of all don't do this 11-16 because that would be 16 subtracted from 11 which is wrong because 1, the sign completely disappears unless you make it -16 plus 11 and 2, it's order would be incorrect. The correct equation should look like this:
-16-11=-27 ( -16-(+11) positive combined with negative is negative).
You can think of it like this: If it's the same sign that's addition or subtraction eg. -4-2 or +6+8, you just add it up together and put the sign in front which you would not have to do for the addition one unless you are asked to.
I hope you find this helpful!

Verify -4 x (5+1) = (-4 x 5) + (-4 x 1)
Simplification: -4 x (5+1) = (-4 x 5) + (-4 x 1)
Take LHS,
-4 x (5+1) = -4x6
= -24
Take RHS,
(-4 x 5) + (-4 x 1) = -20 + (-4)
= -20-4
= -24
LHS= RHS
Hence -4 x (5+1) = (-4 x 5) + (-4 x 1) this equation is verified.
The fundamental guidelines and procedures to simplify any algebraic statement are as follows: By multiplying factors, remove any grouping symbols like brackets and parenthesis. If the words contain exponents, use the exponent rule to eliminate grouping. Add or remove like words to combine them.
Start by resolving all of the terms included in parenthesis to simplify mathematical equations using the order of operations. The exponents should then be solved, followed by any necessary multiplication. Division problems are next, followed by adding and subtracting to wrap things out.

At a local restaurant, the amount of time that customers have to wait for their food is normally distributed with a mean of 40 minutes and a standard deviation of 4 minutes. what percentage of customers have to wait longer than 49 minutes, to the nearest tenth?
Solving for the probability using the z-table, the percentage of customers that have to wait longer than 49 minutes is 1.2 %.
For a normally distributed set of data, given the mean and standard deviation, the probability can be determined by solving the z-score and using the z-table.
First, solve for the z-score using the formula below.
z-score = (x – μ) / σ
where x = individual data value = 49
μ = mean = 40
σ = standard deviation = 4
z-score = (49 - 40) / 4
z-score = (9) / 4
z-score = 2.25
Find the probability that corresponds to the z-score in the z-table. (see attached images)
x = (0.9861 + 0.9893)/2
x = 1.9754/2
x = 0.9877
Subtract it from 1 and multiply by 100 to get the percentage.
