Answer: {11, -11}

Step-by-step-explanation: To solve for x in this equation, since x is squared, we simply take the square root of both sides of the equation to get x by itself.

It's important to remember however that when taking the square root of both sides of an equation, we always use plus or minus.

In other words in this problem, since x² = 121,

x = + or - 11.

A common mistake is to say that x is just equal to 11. But notice that if you plug a -11 back into the original equation, it also checks.

So our answer to this problem is {11, -11}.

Answer: either 11 or -11

Step-by-step explanation:

you have to square root both sides. Then, you are left with the equation [tex]\sqrt{x^{2} } = \sqrt{121}[/tex]. That means that x either equals to 11 or -11.

The mixed fraction number 1 5/8 is equivalent to the decimal number 1.625.

The equivalent is the expression that is in different forms but is equal to the same value.

The decimal number is the sum of a whole number and part of the fraction number. The fraction number is greater than zero but less than one.

The mixed fraction is converted into a fraction number.

1 5/8 = 13/8

Convert the fraction number into a decimal number. Then we have

13/8 = 1.625

Final answer:

1 5/8 is equivalent to the decimal 1.625. To find this, one must convert the fraction 5/8 to its decimal form, 0.625, and then add it to the whole number 1.

Explanation:

The decimal equivalent to 1 5/8 is found by converting the fraction 5/8 to a decimal and adding it to the whole number 1. The fraction 5/8 is equivalent to 0.625 when converted to decimal form. Therefore, when you combine 1 with 0.625, the result is 1.625.

To convert 5/8 to decimal, divide 5 by 8, which equals 0.625. This process is similar to using the reciprocal to multiply, as discussed in the context of 1/8 being a '125–like' number. In this case, divide by 8 rather than multiply.

j=300

Step-by-step explanation:

You multiply each side by 15.

j=300

Answer:

j should equal 300.

Step-by-step explanation:

j/15=20

you have to get j by its self. what you do to one side you must do to the other.

j/15(15) = 20(15)

the fifteens cancel out

j=300

The circumference and radius are different

The circumference and the area of the circle is same.

Step-by-step explanation:

Given,

The radius (r) of the circle = 2 ft

To find the circumference and the area of the circle.

Formula

The circumference of a circle = 2πr

The area of a circle = πr²

Now,

The circumference of a circle = 2π×2 = 4π

The area of a circle = πr² = π×2² = 4π

Hence,

The circumference and the area of the circle is same.

The ratio of white T-shirts to yellow T-shirts should be 7:4, indicating for every 7 white, there are 4 yellow.

The ratio of the number of white T-shirts to the number of yellow T-shirts should be 7:4. This means that for every 7 white T-shirts manufactured, 4 yellow T-shirts should be produced. This is simply a way of representing the proportion of white to yellow T-shirts in a simple and understandable way. Using a ratio is useful to show relative size and proportions.

Answer:

That statement is true which relates to what activity was taken by most of the students of different categories in that particular group during the summers.

Step-by-step explanation:

A two-way frequency table (likewise called a possibility table) is a valuable instrument for inspecting connections between downright factors. The passages in the cells of a two-way table can be frequency checks or relative frequencies (simply like a single direction table). Two-way frequency tables show what number of information focuses fit in every classification.  

Assume you direct a review where you pose every individual two inquiries. When you have wrapped up the overview, you will have two bits of information from every individual. At whatever point you have two bits of information from every individual, you can arrange the information into a two-way frequency table.

The area of the kitchen counter is 21 square ft.

Step-by-step explanation:

Area of the sink = 2 x 3

= 6 square ft.

Area of the kitchen counter = 9 x 3 -(6)

=27 - 6

= 21 square ft.

The area of the kitchen counter is 21 square ft.

The area of the kitchen counter is 21 square feet.

To find the area of the kitchen counter, we need to calculate the total area of the counter first and then subtract the area of the hole for the sink.

Therefore, the area of the kitchen counter, after subtracting the sink hole, is 21 square feet.

Answer:

8

Step-by-step explanation:

the average of 9, 8 , and 7 is 8

The upper quartile for the weights of six puppies, arranged in ascending order and given as 5, 5, 6, 7, 8, 9 ounces, is found by averaging the 4th and 5th points, resulting in 7.5 ounces.

The question seeks to find the upper quartile of the weights of six puppies, which are given in ounces as 8, 5, 7, 5, 6, and 9. To find the upper quartile, step-by-step explanation is necessary. First, we arrange the data in ascending order: 5, 5, 6, 7, 8, 9.

There are 6 data points, so to find the upper quartile (Q3), which divides the top 25% of data from the rest, we identify the data point that falls 3/4th of the way through the dataset. When there are 6 data points, Q3 is calculated by averaging the 4th and 5th data points ((7+8)/2 = 7.5). Therefore, the upper quartile of the data is 7.5 ounces.

5y² + 2xy – 20x - 100

Step-by-step explanation:

Assume that the distance between City A and City B is x miles,

& the speed of the plane from City A to B is y mph;

The return trip is 20 mph slower so the plane's speed is (y – 20) mph

Since time = distance/speed; The time taken by the plane from City A to B is x / y hrs.

The time taken in return flight is;

x / (y - 20) hrs

The layover was 5hrs long. Therefore the total time taken on the who return trip journey is;

x/y  +  x/(y-20)  + 5

multiply each individual fraction with the LCM of the denominators

x(y-20) + xy + 5 y(y-20)

xy -20x +xy + 5y² – 100

The theoretical probability of landing heads up is less than the experimental probability of landing heads up. Statement 2 is true.

Jacob flipped a coin and got heads 68 times and tails 32 times. The total number of flips is not given, so we cannot determine the exact probability of getting either heads or tails. However, we can make some statements about the experimental and theoretical probability based on the information given.

The theoretical probability of landing heads up is 0.5 or 50%, assuming the coin is fair and has two equally likely outcomes. The experimental probability of landing heads up is 68/(68+32) = 0.68 or 68%, which is greater than the theoretical probability of 50%. Therefore, the statement "The theoretical probability of landing heads up is less than the experimental probability of landing heads up" is false.

The theoretical probability of landing tails up is also 0.5 or 50%, assuming the coin is fair. The experimental probability of landing tails up is 32/(68+32) = 0.32 or 32%, which is less than the theoretical probability of 50%. Therefore, the statement "The experimental probability of landing tails up is less than the theoretical probability of landing tails up" is true.

We cannot compare the experimental probability of landing heads up with the experimental probability of landing tails up without knowing the total number of flips. Therefore, the statement "The experimental probability of landing heads up is less than the experimental probability of landing tails up" may or may not be true.

The experimental probability of landing heads up is 0.68 or 68%, and the theoretical probability of landing heads up is 0.5 or 50%. Therefore, the statement "The experimental probability of landing heads up is equal to the theoretical probability of landing heads up" is false.

In summary, statement 2 is true and statements 1, 3, and 4 are false.

The expression 3 x y x 2 x y x 4 x y when simplified is 24y³

From the question, we have the following parameters that can be used in our computation:

3 x y x 2 x y x 4 x y

Evaluate the product of similar variables

So, we have

3 x y x 2 x y x 4 x y = 24 x y x y x y

Evaluate the remaining product of similar variables

So, we have

3 x y x 2 x y x 4 x y = 24y³
