What is the value of t in this equation? (j^-12)^-5=jt
Answers
To find the value of t, apply the exponent rules and simplify to get t = [tex]j^{59[/tex], assuming j is not zero.
The value of t in the equation [tex](j^{-12})^{-5} = j \times t[/tex] can be found by understanding the properties of exponents. Since the equation involves a base raised to an exponent that is also raised to another exponent, one would apply the rule that states [tex](a^n)^m = a^{(n \times m).[/tex] Thus, simplifying gives us [tex]j^{(12 \times 5)} = j \times t \space or j^{60} = j \times t[/tex] Now, assuming that j is not 0, we divide both sides by j to isolate t, resulting in [tex]t = j^{59[/tex], and j will not be equal to zero, hence J [tex]\neq[/tex] 0.

Rewrite 1/6 with a denominator of 18
Answers
Final answer:
To rewrite 1/6 with a denominator of 18, multiply both the numerator and the denominator by 3, resulting in the equivalent fraction 3/18. To confirm its equivalence, simplify 3/18 back to 1/6 by dividing both the numerator and the denominator by 3.
Explanation:
How to Rewrite a Fraction with a New Denominator
To rewrite the fraction 1/6 with a denominator of 18, we need to find a number that we can multiply both the numerator and the denominator of the fraction by so that the denominator becomes 18. Since 6 times 3 equals 18, we will use 3. The fraction then becomes:
(1 x 3) / (6 x 3) equals 3/18.
Verifying the Equivalent Fraction
To verify that 3/18 is indeed equivalent to 1/6, we can simplify 3/18 by dividing both the numerator and denominator by their greatest common factor, which is 3:
3 ÷ 3 / 18 ÷ 3 = 1/6.
This confirms that 3/18 is equal to 1/6 because it simplifies back to the original fraction.

Answers
Answer:
3,1,5,4,8,6 is 1.83 for mean absolute deviation
Step-by-step explanation:
The student correctly calculated the mean and the absolute deviations from the mean, but did not divide the sum of these by the number of data points to find the mean absolute deviation. The correct mean absolute deviation is 11 divided by 6, equal to 1.83 (rounded to two decimal places).
Explanation:Based on your computations, it looks like you did correctly compute the mean absolute deviation (MAD). The first step is to find the mean (average) of the data set, which you correctly found to be 4.5 by summing the data points (3, 1, 5, 4, 8, 6) and dividing by the number of data points (6). Then, you correctly computed the absolute deviations from the mean for each data point (|1-4.5|, |3-4.5|, |4-4.5|, |5-4.5|, |6-4.5|, |8-4.5|), and summed these to get a total absolute deviation of 11. Finally, you divided this total by the number of data points (6) to find the mean absolute deviation. However, you missed this final division step in your calculations. The MAD should be 11/6 = 1.83 (rounded to two decimal places).

Mary wants to make a box. She starts with a piece of cardboard whose length is 15 centimeters and width is 10 centimeters. Then she cuts 4 congruent squares with sides of 3 centimeters at the four corners and folded at the broken lines to make a box.
1) what is the surface area of the box?
2) What is the volume of the box?
3) Explain how you determined the surface area and volume.
Answers
Answer:
surface are: 300 cm2
volume: 450cm3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formulas:
Surface area of a box = 2wl + 2hw + 2 lh
Where w is the width of the box, l is the length of the box, and h is the height of the box.
The top sides and bottom have only length and width, since there is no top side, the surface area is equal to the outer 5 surfaces.
S = wl + 2hw + 2 lh
Replacing with the values given:
S = (15x10)+ 2(3x10)+ 2(15x3)
S = 150+60+90=300 cm2
For the volume we simply apply:
Volume of a rectangular prism: length x width x height
V = 15x10x3 = 450cm3

Who was correct? Which size is the best deal? How should joy and John spend the 10.00
Answers
Final answer:
To determine the best deal, compare unit prices by dividing the price by the size of the items. Spend the $10.00 according to needs and preferences.
Explanation:
In order to determine which size is the best deal, Joy and John need to compare the prices per unit of the items they want to buy. They should divide the price of each item by its corresponding size to calculate the unit price. The item with the lowest unit price would be the best deal.
For example, if Joy wants to buy a 16oz bottle of soda for $1.50 and John wants to buy a 20oz bottle for $2.00, the unit price for Joy's soda would be $1.50/16oz = $0.09/oz, while the unit price for John's soda would be $2.00/20oz = $0.10/oz. Therefore, the 16oz bottle would be the best deal as it has a lower unit price.
As for how they should spend the $10.00, it would depend on their needs and preferences. They could evenly split the money and buy items separately, or they could pool their money together and buy a larger item.

Answers
Answer:
The rating of a brand that costs $3.00 per bag is 7.
Step-by-step explanation:
A simple linear regression equation is used to estimate the value of the dependent variable based upon the independent variable.
The general form of a simple linear regression equation is:
[tex]y=a+bx[/tex]
Here,
y = dependent variable
x = independent variable
a = intercept
b = slope
The output of the least squares regression analysis for predicting rating from price is provided.
So, the dependent variable is the ratings and the independent variable is the price.
The regression equation for predicting rating from price is:
[tex]y=-0.39+2.52x[/tex]
Predict the rating of a brand that costs $3.00 per bag as follows:
[tex]y=-0.39+2.52x[/tex]
[tex]=-0.39+(2.52\times \$3.00)\\=-0.39+7.56\\=7.17\\\approx 7[/tex]
Thus, the rating of a brand that costs $3.00 per bag is 7.

Answers
The surface area of the larger sphere is 366.2496 square centimeter.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
Given that, two spheres have volumes of 87 cm³ and 647 cm³.
We know that, the volume of a sphere = 4/3 πr³
Here, 647 cm³=4/3 πr³
647 = 88/21 r³
r³ = (647×21)/88
r³ = 154.39
r = 5.4 cm
We know that, surface area of a sphere is 4πr².
The surface area of the larger sphere = 4×3.14×5.4²
= 366.2496
Therefore, the surface area of the larger sphere is 366.2496 square centimeter.

Follow this process in reverse to see that x = 4 leads straight up to the blue curve, and then to the left to land on y = 6. Keep in mind that the inverse reverses the input and output process, which is why I started with y instead of x.

What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The value of the expression can be found as shown below,
y = f(x)
When the value of y is 4, the value of x is 6, therefore, we can write f(6)=4.
Now, the given expression can be simplified as,

Can anybody show me the steps to answering this question? 7x - 2z = 4 - xy
(solve for x)
Answers
Answer: 2z+4/y+7
Step-by-step explanation:
We are trying to solve for x
7x-2z=4-xy
Add xy to both sides:
7x-2z+xy=-xy+4+xy= xy+7x-2z=4
Then you add 2z to both sides:
xy+7x-2z+2z=4+2z
xy+7x=2z+4
Then you factor out variable x
x(y+7)=2z+4
You divide both sides by y+7
x(y+7)/y+7= 2z+4/y+7
Which we would get x=2z+4/y+7
Like terms are those terms that are having the same variables, also the variables are of the same order as well. The value of the x can be written as (4 + 2z)/(7 + y).
What are Like terms?Like terms are those terms that are having the same variables, also the variables are of the same order as well.

Take x as common from the left side of the equation,
x(7 + y) = 4 + 2z
