3. What is the value of x? Fill in the blanks

Answer:

$300

Step-by-step explanation:

5% of x + 5 kg = 20

0.05 * x + 5 = 20

0.05x + 5 = 20

0.05x = 20 - 5

0.05x = 15

x = 15 / 0.05

x = $300

Answer:

If the video game that Ethan bought usually costs $39.99, and it was on sale for 20% off, then the discount on the game would be $39.99 x 20/100 = $8.00. To determine the final price of the game after the discount, we can subtract the discount from the original price of the game, which gives us:

Final price = $39.99 - $8.00 = $31.99

Therefore, Ethan paid $31.99 for the video game that was on sale. This can be rounded to the nearest cent to give us a final answer of:

Final price = $31.99 ≈ $32.00.

Therefore, Ethan paid $32.00 for the video game that was on sale.

Answer:

x=4

Step-by-step explanation:

multiply first eq. by 3 and second by 4 to get rid of y

15x+12y=24

8x-12y=68

add the equations

23x = 92

divide both sides by 23

x=92/23=4

Answer:

x = 4

Step-by-step explanation:

Given the 2 equations

5x + 4y = 8 → (1)

2x - 3y = 17 → (2)

Multiplying (1) by 3 and (2) by 4 then adding will eliminate the y- term

15x + 12y = 24 → (3)

8x - 12y = 68 → (4)

Add (3) and (4) term by term to eliminate y, that is

23x = 92 ( divide both sides by 23 )

x = 4

(a) The graph of the linear functions is as attached.

(b) The equation of the linear function in slope-intercept form is; y = x

(c) The equation of the transformed function in slope-intercept form is;

y = x + 2 and y = x - 3

Functions are defined as the relationship between sets of values. For example, in the function; y = f(x), for every value of x there exists a set of y values.

x is the independent variable.

y is the dependent variable.

If the linear function is; y = x,

The equation of the transformation in slope-intercept form is given as;

For translation of 2 units up, we have;

y = x + 2

For a translation of 3 units down, we have;

y = x - 3

Thus, the required graph has been attached and the solution is determined.

The age group "18 up to 40" tends to order the highest average number of condiments, indicating their preference for more condiments on hamburgers.

Based on the provided information, we can conclude the following regarding the number of condiments ordered by different age groups:

0 condiments: 12 customers

1 condiment: 21 customers

2 condiments: 39 customers

3 condiments: 71 customers

0 condiments: 18 customers

1 condiment: 76 customers

2 condiments: 52 customers

3 condiments: 87 customers

0 condiments: 24 customers

1 condiment: 50 customers

2 condiments: 40 customers

3 condiments: 47 customers

0 condiments: 52 customers

1 condiment: 30 customers

2 condiments: 12 customers

3 condiments: 28 customers

To determine which age group tends to order the most number of condiments on average, we can calculate the average number of condiments ordered for each age group based on the provided data:

Age Group: Under 18

Average number of condiments = ((0 * 12) + (1 * 21) + (2 * 39) + (3 * 71)) / (12 + 21 + 39 + 71) = 2.26

Age Group: 18 up to 40

Average number of condiments = ((0 * 18) + (1 * 76) + (2 * 52) + (3 * 87)) / (18 + 76 + 52 + 87) = 2.39

Age Group: 40 up to 60

Average number of condiments = ((0 * 24) + (1 * 50) + (2 * 40) + (3 * 47)) / (24 + 50 + 40 + 47) = 2.07

Age Group: 60 or older

Average number of condiments = ((0 * 52) + (1 * 30) + (2 * 12) + (3 * 28)) / (52 + 30 + 12 + 28) = 1.43

Based on the averages, the age group "18 up to 40" tends to order the highest average number of condiments (2.39), followed by the age group "Under 18" (2.26), "40 up to 60" (2.07), and "60 or older" (1.43).

Therefore, on average, the age group "18 up to 40" tends to order the most number of condiments.

The least whole number possibility for the third side is 8 cm. The greatest whole number possibility for the third side is 22 cm.

A triangle is a three-sided polygon. It is a geometric shape that has three edges and three vertices. Triangles can be classified based on their side lengths (such as equilateral, isosceles, or scalene) or based on the angles between their sides (such as acute, right, or obtuse). Triangles are a fundamental shape in geometry and are used in many branches of mathematics and physics. To form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

Using this rule, we can find the possible range of values for the third side of the triangle.

The least possible length of the third side would be:

8.5cm + 15cm - 15cm = 8.5cm

The greatest possible length of the third side would be:

(8.5cm + 15cm) - 1cm = 22.5cm

The outcome is random if we know the possible values it can have, but not which particular value it takes.

Randomness refers to the property of a process or system where the outcome is uncertain, unpredictable, and not predetermined. In a random process, we know the set of possible outcomes.

But we cannot determine which particular outcome will occur until it actually happens. For example, when flipping a fair coin, the possible outcomes are heads or tails.

But we do not know which one will come up until the coin is flipped. Randomness is a fundamental concept in probability theory and is used to model and analyze a wide range of phenomena.

The order of increasing radius is Sr²⁺, Rb⁺, Br⁻.

The radius of atoms and ions depends on the number of electron shells and the effective nuclear charge. In this case, all three species have the same number of electron shells (n = 5). However, their effective nuclear charges differ due to their varying numbers of protons and electrons.

Sr²⁺ has the smallest radius because it has the highest effective nuclear charge (38 protons, 36 electrons).

which resulting in a stronger attraction between the nucleus and electrons, which contracts the ion. Rb⁺ has a slightly larger radius as it has a lower effective nuclear charge (37 protons, 36 electrons), and Br⁻ has the largest radius due to its lower effective nuclear charge (35 protons, 36 electrons) and additional repulsion between its electrons.

Answer:

(x, y) = (-5/13, -41/13)

Step-by-step explanation: (Assuming the following corrections:)

y = 3x-2

-7x-2y = 9

-7x-2(3x-2) = 9

-7x-6x+4 = 9

-13x = 5

x = -5/13

y = -5/13(3) - 2

y = -15/13 - 2 = -41/13

The probability that the sample mean is less than 341.5 is 0.547.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.

Given,

Mean = 341

Variance = 4

X = N(341, 0.2)

P(Mean ≤ 34.5)

= P( X⁻ ≤ 341.5)

= P(X⁻ - 341/√0.2 ≤ 341.5 - 341/√0.2)

= P( X⁻ ≤ 1.118)

= Ф (1.118)

= 0.547

The probability that the sample mean is less than 341.5 is 0.547.
