Answer: x > -7, see attached

Step-by-step explanation:

    Given:

x + 6 > -1

   Subtract 6 from both sides of the equation:

x > -7

    Graph, see attached. We will graph x = -7, and shade to the right.

Answer:

-60

Step-by-step explanation:

-15 = 1/3x + 5  Multiply all the way through by 3

-45 = x + 15  Subtract 15 from both sides of the equation

-60 = x

Answer: -60 = x

Step-by-step explanation:

If the output value is -15, we need to do this equation.

-15 = (1/3)x + 5.

-5                -5

-20 = (1/3)x

x3     x 3

-60 = x.

Now, let's double-check our answer.

f(60) = (1/3)(-60) + 5

f(-60) = -20 + 5

f(-60) = -15.

This means that x = -60 is our correct answer.

The number of outcomes, using the Fundamental Counting Theorem, is given as follows:

A. Red exactly 3 times and Purple exactly 2: 10.

B. Red at least ounce in 4 spins: 175.

C. Red at least ounce in 5 spins: 781.

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, obtained by the following formula, involving factorials.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Item a is used with the combination formula, as it is an arrangement of five elements with 3 and 2 repetitions, hence the number of outcomes is:

[tex]C_{5,3} = \frac{5!}{3!2!} = 10[/tex]

The Fundamental Counting Principle states that if there are n independent trials, each with [tex]n_1, n_2, \cdots, n_n[/tex] possible results, the number of outcomes is calculated by the multiplication of the factorials as presented as follows:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

For item b, in four spins, each with four outcomes, the parameters are given as follows:

[tex]n_1 = n_2 = n_3 = n_4 = 4[/tex]

Hence the number of outcomes is:

N = 4^4 = 256.

For no red results, the parameters are as follows:

[tex]n_1 = n_2 = n_3 = n_4 = 3[/tex]

Hence:

N = 3^4 = 81.

Hence the number of outcomes with at least one red is:

256 - 81 = 175.

For item 3, the lone difference is that there are five trials, hence:

if M > N then the inequality M/N > N/M will be always true

What is Linear Inequality?

The mathematical expression with unequal sides is known as an inequality in mathematics. Inequality is referred to in mathematics when a relationship results in a non-equal comparison between two expressions or two numbers. In this instance, any of the inequality symbols, such as greater than symbol (>), less than symbol (), greater than or equal to symbol (), less than or equal to symbol (), or not equal to symbol (), is used in place of the equal sign "=" in the expression. Polynomial inequality, rational inequality, and absolute value inequality are the various types of inequalities that can exist in mathematics.

The symbols "" and ">" signify tight inequalities, while "" and "" signify slack inequalities. A linear inequality looks precisely like a linear equation, but the symbol connecting two expressions is different.

As in the question M is always greater N

So, is M is divided by a number that is less than M the answer will always be greater than 1

but on the other hand, if N is divided by a number greater than N then the answer will always be less than 1

Therefore, M/N > N/M will always be True

If a window in the model is 1.5 in. wide, then the actual window is  7.5 feet wide.

A two-term ratio expressed with a second term of one is referred to as a unit ratio. A unit ratio can be created from any ratio. Example. An illustration of a set of marbles is shown below. The set has eight blue marbles and two red marbles.

Having a denominator of 1, a unit rate is a ratio between two separate units. Divide the numerator by the denominator to obtain the unit rate. The unit rate is the decimal number that results. The price of a good or service is the numerator of a ratio called the unit price, and the quantity is the denominator.

Given,

The scale of the Model =5 in: 25 ft.

Dividing both sides by 5 we get,

[tex]\frac{5in}{5}[/tex] :[tex]\frac{25ft}{5}[/tex]

1 inch:5 feet

If a window on the model is 1.5 inch wide, then from the unit ratio we get,

1 inch × 1.5 : 5 feet × 1.5 feet

1.5 Inch : 7.5 feet

As a result, a window that is 1.5 inches wide in the model will actually be 7.5 feet wide.

The compound interest = $5320  

and the total amount = $5832

In this question, we need to find the compound interest and the total amount after an hour if the interest is compounded every ten minutes.

Here, principal P= $512

rate of interest R = 5% per minute

                            = 5 x 10 (interest for every 10 min)

                             = 50

Now n = 60 / 10

        n = 6

So using compound interest formula the total amount would be,

A = P(1 + R / 100)^n

A = 512 (1 + 50/100)^6

A = 512 (3/2)^6

A = 5.2 (1.5)^6

A= $5832

Now the Compound Interest = A – P

                                                 = 5832 – 512

                                                 = $5320  

Therefore, the compound interest = $5320

The number of insects at t=0 is 700, the growth rate is 28e^0.04, population of insects after 10 days is 1044, and the graph of the function is attached.

What is function?

A function, according to a technical definition, is a relationship between a set of inputs and a set of potential outputs, where each input is connected to precisely one output.

a) Number of insects at time (t) = 0 days,

Putting t = 0 in given function:

P(t) = 700e^0.04(0) = 700e^0 = 700

Hence,  the number of insects at t = 0 days is 700.

b) Growth rate of insect population,

In order to find growth we need to differentiate the given function with respect to t.

So,  dP(t)/dt = 700(0.04)e^0.04(0)

= 28e^0.04

Hence, the growth rate is 28e^0.04.

c)  Graph the function is attached in the question.

d) The population of the insects after 10 days,

Answer:

Answer: (D) x= 12

Step-by-step explanation:

First you would distribute 1/6 into everything. 1/6 is equal to .16, so you can do that if you would like. you would get .16x + 4

Next, divide .16 on both sides. It should look like this

.16x/.16 + 4/.16.

Your answer should be x+ 25 = -6, or x = 12.

The probability that the mean of the sample is between 120 and 126 gallons is 0.4176

The normal distribution describes a symmetrical plot of data around its mean value, where the width of the curve is defined by the standard deviation

Given: population mean (µ) = 123, standard deviation(σ) =21 and number of sample (n) = 15

Let X represent the gallons of water: We want to find:

P(120 ≤ X ≤ 126)

Z-score(Z) = (X-µ) / (σ/√n)

Z₁ = (120-123)/ (21/√15) = -0.55

Z₂ = 126-123/ (21/√15)= 0.55

P(-0.55≤ Z ≤ 0.55) = = 0.7088 - 0.2912 = 0.4176

Step-by-step explanation:

The discriminant of the quadratic equation -2x²-5x+7=0 is 81 units when formula of discriminant is (b²-4ac).

Keeping in mind that a, b, and c are the coefficients of your quadratic in standard form, the discriminant is calculated using the formula b squared minus 4ac. It reveals how many possible answers there are to a quadratic equation. There are two solutions if the discriminant is greater than zero. The square root's argument (i.e., its contents), which is the expression b²-4ac, is known as the "discriminant" because using its value, you can "discriminate" between (i.e., be able to distinguish between) the different solution types.

Here,

-2x²-5x+7=0

discriminant=(b²-4ac)

=(-5)²-(4*-2*7)

=25+56

=81 units

If a value of 60° is added to the data, the median change.

The median was 79.5.

The change median is 77.

It is the average value of the set given.

It is calculated as:

Mean = Sum of all the values of the set given / Number of values in the set

Now,

Highest value = 105

Lowest value = 57

Range = 105 - 57 = 48.

Now,

If the value of 80.4 is added the range remains the same because the range is dependent only on the value of the highest and the lowest value.
