H = {z∣z ∈ N and 82 ≤ z ≤ 106}
H has ___ subsets.
H has ___ proper subsets.
Answer:
Step-by-step explanation:
Notice that H is a set with 106 - 81 = 25 elements.
Hence H has [tex]2^{25}[/tex] subsets.
In order to get the proper subsets of H we just need to deduct one from [tex]2^{25}[/tex]
So there are [tex]2^{25}-1[/tex] proper subsets.

Step-by-step explanation:
Find two positive numbers whose difference is 30 and whose product is 2584.
Answer:
[tex]38[/tex] and [tex]68[/tex].
Step-by-step explanation:
Let [tex]x[/tex] be the smaller one of the two number.
[tex]x[/tex] must be a positive integer. The other number would be [tex](x + 30)[/tex].
The question states that the product of the two numbers is [tex]2584[/tex]. In other words:
[tex]x\, (x + 30) = 2584[/tex].
Rearrange this equation and solve for [tex]x[/tex]:
[tex]x^{2} + 30\, x - 2584 = 0[/tex].
The first root of this quadratic equation would be:
[tex]\begin{aligned}x_{1} &= \frac{(-30) + \sqrt{30^{2} - 4 \times (-2584)}}{2} \\ &= \frac{(-30) + \sqrt{900 + 10336}}{2} \\ &= \frac{(-30) + \sqrt{11236}}{2} \\ &= \frac{(-30)}{2} + \sqrt{\frac{11236}{2^{2}}} \\ &= (-15) + \sqrt{2809} \\ &= (-15) + 53 \\ &= 38 \end{aligned}[/tex].
Similarly, the second root of this quadratic equation would be:
[tex]\begin{aligned}x_{1} &= \frac{(-30) - \sqrt{30^{2} - 4 \times (-2584)}}{2} \\ &= (-15) - 53 \\ &= -68\end{aligned}[/tex].
Since the question requires that both numbers should be positive, [tex]x > 0[/tex]. Therefore, only [tex]x = 38[/tex] is valid.
Hence, the two numbers would be [tex]38[/tex] and [tex](38 + 30)[/tex], which is [tex]68[/tex].

Answer:
38 and 68
Step-by-step explanation:
Let x represent the average of the two numbers. Then their product is ...
(x -15)(x +15) = 2584
x^2 = 2584 +225 = 2809 . . . . . . use relation (x -a)(x +a) = x^2 -a^2; add a^2
x = √2809 = 53
Then the two numbers are ...
53 +15 = 68
and
68 -30 = 38
The two numbers are 38 and 68.

Additional comment
Solving the problem in this way is equivalent to writing the quadratic equation for the smallest (or largest) number and solving that by completing the square. The "solution" x = -53 is not relevant in this problem.

Simplify the expression – (7x-6).
Answer:
-7x+6
Step-by-step explanation:
Use the distributive property.
Add the negative in front of each number in the parenthesis.
- (7x) -(-6)
Since 6 is negative, a negative multiplied by a negative is equal to a positive. Change the negative in front of the 6 into a positive.
-7x + 6

If a distribution is skewed to the right with no outliers, which expression is correct?
mean < median
mean ≈ median
mean = median
mean > median
We can’t tell without examining the data.
Answer:
Mean>Median
Step-by-step explanation:
A right skewed distribution with no outliers will have it's mean value greater than the median ( mean > median)
A distribution is said to be right skewed if it's peak is to the left such that it has a long tail to the right.
Conversely, a distribution with it's peak to the right such that it has a long tail is said to be left skewed.
Using the analogy of a boxplot, a right skewed distribution will have it's box to the left and a longer whisker to the right. This means that the median point which is the vertical line in between the box will be lesser than the mean value.
Median < mean = mean > median

I want to know how to find a vertex of a graph?
Answer:
To find the vertex of a parabola, you first need to find x (or y, if your parabola is sideways) through the formula for the axis of symmetry. Then, you'll use that value to solve for y (or x if your parabola opens to the side) by using the quadratic equation. Those two coordinates are your parabola's vertex.
50 points please help me
Answer:
0
Step-by-step explanation:
The slope of the line is 0 as it is parallel to x-axis.
Slope = (y2 - y1)/(x2 - x1)
= (2-2)/(4-(-2))
= 0
Answer:
Slope = 0
Step-by-step explanation:
Taking any two points.
(x1,y1) = (3,0)
(x2,y2) = (-1,0)
Now,

If two rectangles have the same perimeter, do they have to be congruent?
Explain your thinking,
9514 1404 393
Answer:
no
Step-by-step explanation:
For the perimeter to be the same, the sum of side lengths must be the same. That does not mean the side lengths themselves must be the same.
A 4×4 rectangle (square) and a 5×3 rectangle have the same perimeter, but are not congruent.

What is the correct elements in the set?
An exponential function contains the points: (2,121) and (3,133.1)
What is the exponential function that contains these points?
y=ab^x
121= ab^2
133.1= ab^3
we divide the 2 equations
[tex] \frac{121}{133.1} = \frac{a {b}^{2} }{a {b}^{3} } [/tex]
0.9 = b^-1
b = 1.1
121 = a (1.1)^2
121 = a × 1.21
a = 100
y=100 × ((1.1)^x) is the function

If a floor is 9 feet, how many 6 square inch tiles do you need?
Answer:
A floor 9 feet by 12 feet, is to be tiled with 4-inch-by-6-inch tiles.
Step-by-step explanation:
How many tiles are needed to cover the floor?
9 ft is 9 x 12 = 108 in
12 ft is 12 x 12 = 144 in.
The area of the floor is 108 in x 144 in = 15,552 sq. in.
Each tile is 4 in x 6 in = 24 sq. in.
Dividing 15,542 sq. in by 24 sq. in gives an answer of 648 tiles.
