A coin jar contains 10 quarters, 6 dimes and 8 nickels. Find the probability that two quarters are chosen random from the jar.

aliina [53]

Answer: 0.1630

Step-by-step explanation:

Number of quarters = 10

Number of dimes = 6

Number of nickels = 8

Total number = 10+6+8 = 24

Probability of choosing the first quarter will be: = Number of quarters/Total number of money

= 10/24 = 5/12

Since a quarter has been selected, the total number will reduce to 23 the next time a quarter is choosing and the number of quarters will now be 9. Therefore, the probability of choosing the second quarter will be: = 9/23

Therefore, the probability that two quarters are chosen random from the jar will be:

= 5/12 × 9/23

= 45/276

= 0.1630

What is the slant height x of the square pyramid? Enter your answer in the box, express your answer in radical form.

Nadya [2.5K]

For this case we have a rectangle triangle where we know:
hypotenuse of the triangle.
Angle between the base of the triangle and the hypotenuse.
We want to find the height of the triangle.
For this, we use the following trigonometric relationship:
 $sine (60) = x / 8
$
 From here, we clear the value of x.
We have then:
 $x = 8 * sine (60)

x = 6.93 m$ 
Answer:
The inclined height of the pyramid is given by:
x = 6.93 m

Y=(1/2)^x +2. What is the horizontal asymptote of this function?

professor190 [17]

$\lim_{x\to -\infty} \left(\frac{1}{2}\right)^x+2=\infty+2=\infty\\
\lim_{x\to \infty} \left(\frac{1}{2}\right)^x+2=0+2=2\\$

There is one-sided horizontal asymptote $y=2$
