Answer:

3rd and 5th options (check below)

Step-by-step explanation:

The gift card has $22.20

After payment he had $1.90 left

What was charged for the 4 tire patches? $22.90 - $1.90

How many tire patches did he pay for? 4

Let the patch be X, 4 patches will be 4X

4X = 22.20 - 1.90

The cost of the patches + the balance on the gift card is also 22.20

4x + 1.90 =22.20

If you Subract the cost of 4tire patches from 22.20, you will have 1.90 on the gift card

22.2 - 4X = 1.9

the fraction of people in the room with blue eyes is 9/50.

If approximately 18 out of every 100 people have blue eyes, then the fraction of people with blue eyes can be expressed as 18/100 or 0.18. To find the fraction of people with blue eyes in a room of 50 people, we need to multiply this fraction by the total number of people:

(0.18) x 50 = 9

So, there are approximately 9 people in the room with blue eyes. To express this as a fraction with a denominator of 50, we can write:

Answer:

∠ 6 = 59°

Step-by-step explanation:

∠ 3 and ∠ 8 are same- side interior angles and sum to 180° , that is

∠ 3 + ∠ 8 = 180°

Numbers are mathematical objects used for counting, measuring and marking. The original examples are the natural numbers 1, 2, 3, 4, etc. Numbers can be represented by number words. More generally, individual numbers can be represented by symbols, called numerals; for example, "5" is the number representing the number five. Since only relatively few symbols can be memorized, base numbers are usually organized into a number system, which is an organized way of representing any number.

The most common numeral system is the Hindu-Arabic numeral system, which allows any number to be represented using a combination of ten basic numeral symbols, called numerals. In addition to being used for counting and measuring, numbers are often used for labels (like phone numbers), orders (like serial numbers), and codes (like ISBNs) . In common usage, a number is not clearly distinguishable from the number it represents.

According to the question:

Number of chairs = 6 and

Number of rows =x

The length of JL can be found by subtracting the length of ML from the sum of LK and LN. Therefore, JL = 28 + 16 - 12 = 32.

To find the length of JL, first we can add the lengths of LK and LN. LK = 28 and LN = 16, so 28 + 16 = 44. Then, we can subtract the length of ML from the sum of LK and LN. ML = 12, so 44 - 12 = 32. Therefore, JL = 32.

This can be done by visualizing the diagram. The length of JL can be found by adding the lengths of LK and LN, which can be seen as the two sides of the right triangle that form the line MN. Then, the length of ML can be subtracted from the sum of LK and LN to get the length of JL.

To construct a confidence interval with a 90% confidence level, we need to find the critical value t0.05/2. This critical value is found by using the t-distribution with a confidence level of 90% (0.90) and degrees of freedom equal to the sample size minus 1 (180 - 1 = 179). We can then use this critical value to calculate the margin of error of the confidence interval, which is equal to the critical value multiplied by the standard error (s/√n). In this example, that results in a margin of error of 1.699*(6.2/√180) = 1.9.

Therefore , the solution of the given problem of probability comes out to be there is a 0.0084 percent chance that a raw number chosen at random will be higher than 96.

The primary goal of the designs inside a practice known as criteria is the evaluation of the likelihood that a claim is accurate or that a specific event will occur. Any number between 0 and 1 can be used to represent chance, with 1 usually representing a range level of certainty and 0 typically representing possibility. A probability diagram shows the chance that a specific event will occur. Just the digits 0% and approximately 100% make up the decimal 1, 0, and 0.

Here,

To resolve this issue, we can use the conventional normal distribution. First, we must standardise the 96 number using the following equation:

=> z = (x - μ) / σ

where the mean is, the standard deviation is, and x is the number we're interested in. When we enter the numbers, we obtain:

=> z = (96 - 85) / 4.6 = 2.3913

The area to the right of z = 2.3913 can then be determined using a calculator or a conventional normal distribution table.

The area to the right of 2.39, according to a standard normal distribution chart, is 0.0084. (rounded to four decimal places).

As a result, there is a 0.0084 percent chance that a raw number chosen at random will be higher than 96.

By making linear equations for given situation, the vendor sold 34 hot dogs and 84 sodas at the football game.

What is a linear equation, exactly?

A linear equation is an algebraic equation in which each term a constant or variable. In other words, a linear equation is an equation of the form:

y = mx + b

where y and x are variables, m is the slope of the line, and b is the y-intercept (the point where the line intersects the y-axis).

Now,

Let x be the variable or number of hot dogs sold.

Then, according to the problem, the number of sodas sold is 50 more than the number of hot dogs sold. Therefore, the number of sodas sold can be represented as (x + 50).

We know that the total number of sodas and hot dogs sold is 118, so we can write an equation:

x + (x + 50) = 118

Simplifying and solving for x:

2x + 50 = 118

2x = 68

x = 34

Therefore, the number of hot dogs sold is 34, and the number of sodas sold is (x + 50) = 84.

So, the vendor sold 34 hot dogs and 84 sodas at the football game.

Given that,

Base = 7m.

Height = 3m.

Length = 11m.

Therefore, The area of the triangle on one side = [tex]\frac{1}{2} bh[/tex]

                                                                                = [tex]\frac{1}{2}[/tex] × 7 × 3

                                                                                = 21/2

                                                                                = 10.5 m².

The volume of the prism = area of the triangle × height

The numeric value of the expression is given as follows:

To obtain the numeric value of a function or of an expression, we substitute each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.

The function for this problem is given as follows:

f(x) = 5x² - 6x + 1.

The numeric value at x = x + h is given as follows:

f(x + h) = 5(x + h)² - 6(x + h) + 1

f(x + h) = 5(x² + 2xh + h²) - 6x + 6h + 1

f(x + h) = 5x² + 10xh + 5h² - 6x + 6h + 1

Hence:

f(x + h) - f(x) = 5x² + 10xh + 5h² - 6x + 6h + 1 - 5x² + 6x + 1

f(x + h) - f(x) = 10xh + 5h² + 6h

f(x + h) - f(x) = h(5h + 10x + 6).

Note that where the above conditions exists with regard to the geometric ratios, the sum of the antecedents is approximately 445.31.

Let the three continuous geometric ratios be a, ar, and ar^2, where a is the first term and r is the common ratio. Then the equality can be written as:

a/ar + ar/ar² + ar² = 3/4

Simplifying this equation, we get:

1/r + r + r² = 3/4

Multiplying both sides by 4r², we get:

4r + 4r³ + 4r⁴ = 3r²

Rearranging, we get:

4r⁴ + 3r² - 4r = 0

We can factor this equation as:

r(4r³ - 4r² + 3) = 0

Since r cannot be zero, we must solve the cubic equation:

4r³ - 4r² + 3 = 0

Using a numerical method or a computer program, we can find that one real root of this equation is approximately 0.8202.

Now that we know the value of r, we can use the difference between the largest and minor consequent to find the value of a. The largest consequent is ar², and the minor consequent is a, so we have:

ar² - a = 120

Substituting r = 0.8202, we get:

a(0.8202)² - a = 120

Simplifying, we get:

a = 120 / (0.6721)

a ≈ 178.63

Finally, we can calculate the sum of the antecedents:

a + ar + ar² = 178.63 + (178.63)(0.8202) + (178.63)(0.8202)²

Summing these terms, we get:

a + ar + ar² ≈ 445.31
