Step-by-step explanation:

The system of the equation has x = 0.

The two equations are,

y = 2x + 6x + 4

y = -4x + 4

Now equating the equation, we have

2x + 6x + 4 = -4x + 4

8x + 4 = -4x + 4

12x = 0

x = 0

Therefore the system of the equation has x = 0.

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.

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.

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.

The inequality that represent the possible length of the third side is

                    7 < x < 17

According to the triangle inequality theorem, the sum of any two sides of a triangle must be greater than the measure of the third side of the triangle.

We have been given measure of two sides which are 5 and 12. Then the possible length for the third side has two condition

Let the third side be x unit.

First condition,      x + 5 > 12

                              x > 7

Second condition,  12+ 5 > x

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.

The commutative property of real numbers states that:

a + b = b + a where a,b ∈ R

= 37 • 1 - Inverse property of multiplication.

The inverse property of real numbers states that:

a + 1/a = 1 where a ∈ R

Based on the given task content, the division of 4,550 by 64 is approximately 71.09 to two decimal places.

4,550 divided by 64

The divisor which is a number or expression that another number divides is 4,550

The dividend which is the number or the expression which is used to divide another is 64

The quotient here simply refers to the result which is obtained by dividing one number by another.

4,550 divided by 64

= 4,550 / 64

= 71.09375

This result above can be correctly approximated to two decimal places, that is, two values after the decimal point.

Approximately,

71.09375

= 71.09

This is a number expressed in the decimal system (base 10), particularly fractional numbers.

For instance, in the illustration below:

The value of the expression log₈32 by using the change of base formula is 1.67.

Given that the expression is log₈32.

We are required to find the value of the expression using change of base formula.

The change of base formula is basically used at a time when we have to re-write a logarithm operation as a fraction of logarithms with a new base to find the value of the logarithm.

The result given by it is [tex]log_{a}b[/tex]=log b/log a.

The expression is log₈32.

log₈32=log 32/log 8

=log [tex]2^{5}[/tex]/ log [tex]2^{3}[/tex]

=5log 2/3log 2

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 %
