The price of an American Airlines ticket to Boston increased to $600. This is a 15 percent increase. What was the old fare? Roun

FinnZ [79.3K]

The old fare was "x"
then it got bumped up by 15%, and the new price is x + 15% of x,
so.. one could say, that "x" is the 100%, then you add a 15% to
it, to get 600
thus $\bf \begin{array}{ccllll}
amount&\%\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
x&100\\
600&100+15
\end{array}\implies \cfrac{x}{600}=\cfrac{100}{100+15}$

solve for "x"

3. Two balls are drawn in succession without replacement from an urn containing 4 red balls and 3 blue balls. Find the probabili

choli [55]

Answer:

X ____ 0 ______ 1 _______ 2

P(x) __ 1/7 _____ 4/7 _____ 2/7

Step-by-step explanation:

Given that :

Number of red balls = 4

Number of Blue balls = 3

Total number of balls = (4 + 3) = 7

Picking without replacement :

Number of picks = 2

1st pick is red :

Probability = (required outcome / Total possible outcomes)

USing combination formula :

nCr = n! / (n-r)! r!

Total possible outcome :

7C2 = 7! / 5!2! = 7*6 / 2 = 42 / 2 = 21

X = number of red

For red = 0;

P(x =0) = required outcome / Total possible outcomes

P(x = 0)

Required outcome : [4C0 * 3C2)]

P(x = 0) = [(4C0 * 3C2)] / 21 = (1*3)/21 = 3/21 = 1/7

P(x = 1)

Required outcome : [4C1 * 3C1)]

P(x = 1) = [(4C1 * 3C1)] / 21 = (4*3)/21 = 12/21 = 4/7

P(x = 2)

Required outcome : [4C2 * 3C0)]

P(x = 2) = [(4C2 * 3C0)] / 21 = (6*1)/21 = 6/21 = 2/7

Hence ;

X ____ 0 ______ 1 _______ 2

P(x) __ 1/7 _____ 4/7 _____ 2/7

The graph shows the total mass loss of the Greenland ice sheet since 2007. Write a conjecture using the graph.

Gelneren [198K]

The conjecture or hypothesis given based on the attached graph is that there has been a general increase in the total loss of the Greenland Ice Sheet since 2007. However, since 2013, the rate at which the total loss increased began to decline.

<h3>What is a conjecture in math?</h3>

In mathematics, a hypothesis or a conjecture is a speculative conclusion or assertion that is stated without evidence.

<h3>How do you write a Conjecture ?</h3>

You must discover a trend or make some type of remark. For example, you may have observed that the list is increasing by twos.

You draw a conclusion based on the pattern you saw, just as you did when you determined that 18 would be the following number.
