Answer:

10 and 14

Step-by-step explanation:

let the 2 numbers be x and y , then

[tex]\frac{1}{2}[/tex] (x + y) = 12 ( multiply both sides by 2 to clear the fraction )

x + y = 24 ( subtract x from both sides )

y = 24 - x → (1)

and

[tex]\frac{1}{4}[/tex] xy = 35 ( multiply both sides by 4 )

xy = 140 → (2)

substitute y = 24 - x into (2)

x(24 - x) = 140

24x - x² = 140 ( subtract 140 from both sides )

24x - x² - 140 = 0 ( multiply through by - 1 and arrange in standard form )

x² - 24x + 140 = 0 ← in standard form

(x - 10)(x - 14) = 0 ← in factored form

equate each factor to zero and solve for x

x - 10 = 0 ⇒ x = 10

x - 14 = 0 ⇒ x = 14

corresponding values of y are by substituting values of x into (1)

x = 10 → y = 24 - 10 = 14

x = 14 → y = 24 - 14 = 10

then the numbers are 10 and 14

In statistics, an outlier is a data point that differs significantly from other observations.

Step-by-step explanation:

The EAN-13 code of Mr. Chips Nacho Cheese Flavor (100 g) 4-800016-653094 is valid.

To check the validity of the EAN-13 barcode, we need to perform a computation based on the numbers in the code. The EAN-13 code consists of 13 digits, where the first digit represents the number system, the next five digits represent the manufacturer code, the following five digits represent the product code, and the last digit is the check digit.

The check digit is calculated based on the previous 12 digits using a specific algorithm.

For the given EAN-13 code 4-800016-653094, we can extract the previous 12 digits as 480001665309. To calculate the check digit, we need to multiply the first, third, fifth, etc. digits by 3, and the second, fourth, sixth, etc. digits by 1, and then sum these products. In this case, the calculation is as follows:

(4x3) + 8 + (0x3) + 0 + (0x3) + 1 + (6x3) + 6 + (5x3) + 3 + (0x3) + 9 = 74

The check digit is then the smallest number that, when added to the sum above, results in a multiple of 10. In this case, the check digit is 6, since 74 + 6 = 80, which is a multiple of 10.

Answer:

(1, - 2 )

Step-by-step explanation:

9x - 3y = 15 → (1)

3x + 3y = - 3 → (2)

add (1) and (2) term by term to eliminate y

(9x + 3x) + (- 3y + 3y) = 15 - 3

12x + 0 = 12

12x = 12 ( divide both sides by 12 )

x = 1

substitute x = 1 into either of the 2 equations and solve for y

substituting into (2)

3(1) + 3y = - 3

3 + 3y = - 3 ( subtract 3 from both sides )

3y = - 6 ( divide both sides by 3 )

y = - 2

solution is (1, - 2 )

Mrs. Cook was able to make 60 sandwiches using 6 jars of jelly.

Mrs. Cook was able to make 60 sandwiches. To find the answer, we can use the following equation:

Total number of sandwiches = (Total amount of jelly) / (Amount of jelly used per sandwich)

In this case, the total amount of jelly is 6 jars, and the amount of jelly used per sandwich is 1/10 jar.

Plugging these values into the equation gives us: Total number of sandwiches = (6 jars) / (1/10 jar)

To solve this equation, we can multiply the numerator and denominator by 10 to get rid of the fraction:

Total number of sandwiches = (6 jars × 10) / (1/10 jar × 10)

Simplifying gives us: Total number of sandwiches = 60 jars / 1 jar

Finally, we can cancel out the "jars" units to get:

Total number of sandwiches = 60

Answer:

Step-by-step explanation:

A surface analysis chart is a type of weather map that displays information about the current pressure and wind patterns over a particular region. The chart provides a snapshot of the weather conditions at a specific point in time and helps meteorologists to identify and track the location, movement, and development of high- and low-pressure systems, fronts, and other weather features.

The surface analysis chart typically shows a map of the Earth's surface with various meteorological symbols and information, including isobars (lines of equal pressure), fronts (boundaries between different air masses), and wind direction and speed. The chart may also include information about temperature, precipitation, and cloud cover.

Surface analysis charts are used in weather forecasting, air traffic control, and other applications where an understanding of current weather conditions is important. They provide important information for short-term weather forecasting, such as predicting the location of fronts and the development of thunderstorms, and for long-term weather planning, such as determining the most suitable routes for shipping or aviation.

Answer:

Uncle Mike was 7 times as old as Sally 17 years ago.

Step-by-step explanation:

Let's call Uncle Mike's current age "x."

Sally is 12 years old, so x = 12 * 3 = 36 years old.

We are looking for years that must pass before Uncle Mike is only twice as old as Sally. So we need to find the age when x = 2 * (12 + n), where n is the number of years that have passed. Solving for n:

36 = 2 * (12 + n)

36 = 24 + 2n

12 = 2n

n = 6

So, six years must pass before Uncle Mike is only twice as old as Sally.

To find out how many years ago Uncle Mike was 7 times as old as Sally, we need to find the age when x = 7 * (12 - m), where m is the number of years ago. Solving for m:

36 = 7 * (12 - m)

36 = 84 - 7m

120 = 7m

m = 17

So, Uncle Mike was seven times as old as Sally 17 years ago.

The equation of the nth term is a(n) = 2-8n

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference from any succeeding term to its preceding term remains constant throughout the sequence. The constant difference is called common difference of that arithmetic progression.

The common difference = -14-(-6) = -14 +6 = -8

The first term is a1

The nth term of an arithmetic sequence =

a(n )= a1+(n-1)d

a(n) = a1+(n-1)-8

a(n )= a1-8n+8

if a1 = -6

a(n) = -6-8n +8

a(n) = 2-8n

In maths, A∩B refers to the intersection of two sets, A and B. This means that it includes all the elements that are in both sets A and B. For example, if A = {1, 2, 3, 4} and B = {3, 4, 5, 6}, then A∩B = {3, 4}, as these are the elements that are in both sets.

To find the intersection of two sets, you can list out all the elements in each set and then look for the ones that are in both. Alternatively, you can use a Venn diagram to visually represent the two sets and their intersection.

Here is an example using a Venn diagram:

A = {1, 2, 3, 4}
B = {3, 4, 5, 6}



As you can see, the intersection of A and B is the area where the two circles overlap, which includes the elements 3 and 4. Therefore, A∩B = {3, 4}.
