On Decemeber 18th, there is a 75% chance that Santa will come to the mall that day and a 55% chance that your best friend will b

goblinko [34]

Answer:

<u>The probability that Santa will come to the mall OR your best friend will be there is 47.4%</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Probability that Santa will come to the mall on December 18th = 75%

Probability that your best friend will be at the mall on December 18th = 55%

Probability that Santa will come to the mall on December 18th AND your best friend will be there = 75% * 55% = 41.3% not just 40%

2. What is the probability that Santa will come to the mall OR your best friend will be there?

For answering this question, we should calculate first the probability that Santa will not come to the mall on December 18th AND your best friend will not be there, this way:

Probability that Santa will not come to the mall on December 18th AND your best friend will not be there = 25% * 45% = 11.3%

Now, we know that the probability that Santa will come to the mall on December 18th AND your best friend will be there is 41.3% and the probability that Santa will not come to the mall on December 18th AND your best friend will not be there is 11.3%.

Therefore, the probability that Santa will come to the mall OR your best friend will be there is:

100% - 41.3% - 11.3% = 100% - 52.6% = 47.4%

<u>The probability that Santa will come to the mall OR your best friend will be there is 47.4%</u>

Imagine we are throwing a five-sided die 50 times. On average, out of these 50 throws, how many times would this five-sided die

olganol [36]

16.6 times because if there is 3 numbers you simply divide it into 50

Miguel sells a house for 275,000. His commission for the sale is 7,562.5

valentinak56 [21]

Answer:

$2.75\%$

Step-by-step explanation:

To find what percentage a certain value is of another value, simply divide the first value by the second, respectively.

We want to find want percentage that 7,562.5 is of 275,000. Therefore, we will divide 7,562.5 by 275,000 to obtain a decimal:

$\frac{7,562.5}{275,000}=0.0275$

To convert from a decimal to a percentage, multiply by 100:

$0.0275 \cdot 100=\boxed{2.75\%}$

The sides of a triangle are 1, x, and x2. what are possible values of x?

Whitepunk [10]

The sides of the triangle are given as 1, x, and x².

The principle of triangle inequality requires that the sum of the lengths of any two sides should be equal to, or greater than the third side.

Consider 3 cases
Case (a): x < 1,
Then in decreasing size, the lengths are 1, x, and x².
We require that x² + x ≥ 1
Solve x² + x - 1 =
x = 0.5[-1 +/- √(1+4)] = 0.618 or -1.618.
Reject the negative length.
Therefore, the lengths are 0.382, 0.618 and 1.

Case (b): x = 1
This creates an equilateral triangle with equal sides
The sides are 1, 1 and 1.

Case (c): x>1
In increasing order, the lengths are 1, x, and x².
We require that x + 1 ≥ x²
Solve x² - x - 1 = 0
x = 0.5[1 +/- √(1+4)] = 1.6118 or -0.618
Reject the negative answr.
The lengths are 1, 1.618 and 2.618.

Answer:
The possible lengths of the sides are
(a) 0.382, 0.618 and 1
(b) 1, 1 and 1.
(c) 2.618, 1.618 and 1.

The line L1 has equation 2x+y=8.The line L2 passes through the point A(7,4) and is perpendicular to L1.

baherus [9]

If m1 and m2 are the slopes of each line, for them to be perpendicular you gotta solve
m1 * m2 = -1
