[tex]15d^1^3[/tex]
Step-by-step explanation:
[tex](5d^6)(3d^7)\\\\= 5*3*d^6*d^7\\\\= 15*d^6^+^7\\\\= 15d^1^3[/tex]
Important things to note:
- The 5 and 3 are multiplied together because they are both regular numbers
- The [tex]d^6[/tex] and [tex]d^7[/tex] are multiplied together because they are they same variable
- When multiplying values with exponents, the exponents are added together
Answer: Hope this explain this for you!
15d^13
Step-by-step explanation:
Let's start off with the equation:
(5d^6) (3d^7)
Now I will solve it as:
5 * 3 * d^6 * d^7
First, I will start of by multiplying the
regular numbers as they are like terms,
this will simplify the equation.
15 * d^6 * d^7
An important thing to remember is that
when you multiply exponents, you just
add them up. And another thing to note
is a variable without a number is equal.
to 1, 1*1=1 and d*d=d.
15 * d^6 * ^7
15 * d^13
And now, we can remove the multiplication sign and we get 15d^13.Brainliest please?

A box without a top is to be made from a rectangular piece of cardboard, with dimensions 4 in. by 8 in., by cutting out square corners with side length x and folding up the sides.
Write an equation for the volume V of the box in terms of x.
Use technology to estimate the value of x, to the nearest tenth, that gives the greatest volume. Explain your process.
Answers
Step-by-step explanation:
the answer is in the three pics
The value of x for the greatest volume is 1.5 in.
What is volume?Volume is the measure of the 3-dimensional space occupied by matter, or enclosed by a surface, measured in cubic units.
Given that, A box without a top is to be made from a rectangular piece of cardboard, with dimensions 4 in. by 8 in., by cutting out square corners with side length x and folding up the sides.
v = x(8-2x)(10-2x)
v = x(4x²-36x+80)
v = 4x³-36x²+80x
Now,
The greatest volume will occur when the velocity of v(x) is zero.
dv/dx = 12x²-72x+80
dv/dx = 0 when
x = (72±√1344)/24
Since, 0 < x < 4 (because of the constraints on x for volume to have meaning)
x ≈ 1.5 in
Hence, the value of x for the greatest volume is 1.5 in.

Tamara finds the sum of two number cubes rolled at the same time. The chart below shows all possible sums from the 36 possible combinations when rolling two number cubes. How many times should Tamara expect the sum of the two cubes to be equal to 3 if she rolls the two number cubes 180 times?
Answers
Answer:
Tamara should expect the sum of the two cubes to be equal to 5 20 times.
Step-by-step explanation:
The sample space of rolling a number cube are:
S = {1, 2, 3, 4, 5, 6}
If two such cubes are rolled together, then the sum of the two cubes will be 5 for the combinations below:
S₁ = {(1, 4), (2, 3), (3, 2) and (4, 1)}
The total number of outcomes will be, N = 36.
Compute the probability that the sum of rolling two numbered cubes as follows:
Let X = number of time the sum of the two numbers on two cubes is 5.
Two numbered cubes are rolled n = 180 times.
The event of getting a sum of 5 in independent of the other results.
The random variable X follows a Binomial distribution with parameters n = 180 and p = .
The expected value of X is:
Compute the expected number of times Tamara expects the sum of the two cubes to be equal to 5 as follow:
Thus, Tamara should expect the sum of the two cubes to be equal to 5 20 times.

Probability plots might be the best way to determine whether your data follow a particular distribution. If your data follow the straight line on the graph, the distribution fits your data. This process is simple to do visually. Informally, this process is called the “fat pencil” test.
For skewed distributions, it is quite common to have one tail of the distribution considerably longer or drawn out relative to the other tail.
As, it is known that, when the distribution of data is left-skewed, the mean is less than median.
In any research of distribution, the distribution is described by its shape. If there are more higher values than lower values, the distribution is skewed left.The distribution can be described by its center. If the distribution is skewed left or right, the median is an accurate measure of center.The distribution can be described by its spread. If the data set does not have an outlier, the interquartile range is an accurate measure of spread.Learn more about distribution of data here:

The play area in a local school is a rectangle that is 18’ x 40’ in size. The management about it to put a 4-foot side walk all around the building, leaving a 2-foot space for plants between the building and the sidewalk. Give the perimeter of the outer edge of the sidewalk and the area of the sidewalk itself?
Answers
Answer:
528 is the Area
148 is the Perimeter
Step-by-step explanation:
We know that there is a 4 foot ring around the building so we add 8 feet to 18 x 40 which is 26 x 48.
To find the perimeter we take the Length and Height times 2 and then add that together.
26•2=52
48•2=96
52+96=148
148 is the Perimeter.
To find the area of the sidewalk.
We have to multiply the area together.
4•48=192•2=384
18•4=72•2=144
528
Add that together you have the area of the sidewalk

Aubrey claims that if the dimensions of the parallelogram shown are doubled, then the area of the larger parallelogram will be 4 times more than the original. Which statement about her claim is completely true?
A parallelogram with a base of 6 inches and height of 3 inches. A side has a length of 5 inches.
Aubrey is correct because the area of the new parallelogram is 12 (6) = 72 square inches. The original area is 18 square inches. Since 4 (18) = 72, the new parallelogram has 4 times the area of the original.
Aubrey is correct because the area of the new parallelogram is 10 (7) = 70 square inches. The original area is 18 square inches. Since 4 (18) = 72, it is about 4 times larger than the original.
Aubrey is incorrect because if one doubles each dimension, then the area will automatically be doubled as well. The original area is 18 square inches so the new parallelogram will have an area of 2 (18) = 36, or two times more than the original.
Aubrey is incorrect because if one doubles each dimension, then the area will automatically be doubled as well. The original area is 30 square inches so the new parallelogram will have an area of 2 (30) = 60, or 2 times more than the original.
