2. What is the value of the expression when a = 6 and b = -4? Show your work to support your answer.

Since the ratio is 12 : 5, the statement which is true is there are more than twice as many cows as there are sheep.

The ratio between the number of cows to number of sheep in a field is given as:

12 : 5

Now,

let the number of sheep be 5 x.

So, the number of cows will be 12 x.

So, we get that:

12 x > 2 ( 5 x)

12 x > 10 x

So, the statement which is true will be:

there are more than twice as many cows as there are sheep

Therefore, since the ratio is 12 : 5, the statement which is true is there are more than twice as many cows as there are sheep.

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

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

Now rounding off to 4 decimal places, we get that:

= 0.0183

Therefore, the value of the expression e⁻⁴ is 0.0183.

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.

2 x 10^5 miles is the correct answer.

A power of ten in mathematics is defined as one of the integer powers of a number multiplied by ten. Integers can be both positive and negative. To find the multiple of ten, we need to add 10 to itself several times (if the power is a positive integer).

if we have a value that says ten ^5,

then this value is equal to:

= 10 x 10 x 10 x 10 x 10

= 10,0000

Also, by the definition of a multiple of ten, the number 1 is a power of 10 as well if we take the 0th power of 10.

10^0 = 1

Whatever the integer is, it is multiplied by 10 n times. So, the long form of a power of 10 is the number 1, followed by n zeros, where the n number is greater than the 0 value.

Here the distance that is given to us is:

238,855

We can also write it as,

2 x 10 ^ 5.

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.

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.

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.

% = (1 - 0.9877) x 100

% = 0.0123 x 100

% = 1.23%

% = 1.2 %

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.

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.
