The minimum number of friends for which Jump it Up is 7
A two-variable linear equation can be thought of as a linear relationship between x and y, or two variables whose values rely on each other (often y and x) (usually x).
Sky high pricing:
$50 for <=10 people and $5 per person after that
Jump it Up pricing:
Set up charges = $70
Per person charges = $2
Let p be the number of people
Formulating the equation we get:
50 + 5p = 70 + 2p
3p = 20
p = 6.66
or p =7
So, Jump it up will be less expensive for 7 friends

What is the slope of a line which passes through points ( p,q) and (x,y)?The slope of parallel lines is the same. Slopes of perpendicular lines are negative reciprocals of each other. The slope of a line or straight object is the ratio of how much amount of rising occurs in correspondence to the increment in the run.

Answers
Spanish club has 48 tickets which must be sold to reach the fund-raising goal as profit of $600.
What is profit?
In mathematics, the term profit can be explained as the amount which is on the standard cost price. For the profit, the amount of the commodity can be designed by the shopkeeper which is bigger amount as per the cost price.
According to the question, the total profit from the Spanish club fundraiser varies directly with the number of dinner tickets sold.
If the sale of 14 tickets results in a profit of : $175.
Therefore, Profit in 1 ticket = 175/14 = 12.5 dollars
Let us assume 'x' tickets are sold in order to reach the fund-raising goal of $600.
x = (14/175)(600) = 48
x = 48 tickets

The average distance between students in public is smaller than that in private.
While the data for the public appears to closely follow a bimodal distribution, the data for the private appears to be negatively skewed, meaning that the tail is lopsided to the left. However, it might be nearly symmetrical. While the modal class for the public is 11–50, it is 101–500 for private.

The answer is 10 and one half pounds
Explanation:

10 and one half pounds use to make 21 small vases.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Sandy uses clay= 3 1/2 pounds for 7 vase
So, for 1 vase amount of clay used
= 7/2 x 1/7
= 1/2 pounds
Now, for 21 small vases amount of clay used
=21 x 1/2

Describe this sequence.
Answers
The given sequence is
1, 1/2, 1/4, 1/8......
we can see that the ratio of the consecutive terms is the same. We have
1/2/1 = (1/4)/(1/2) = (1/8)/(1/4) = 1/2
This means that it is a geometric sequence
To find the amount of the substance left after 21 half lifes, we would find the 21st term of the sequence. The formula for finding the nth term of a geometric sequence is
an = a1r^(n - 1)
a1 = 1
n = 21
r = 0.5
Thus,
a21 = 1 * 0.5^(21 - 1) = 0.5^20
a21 = 0.00000095367
a21 = 1/1048576
