A coin is tossed then a number 1-10 is chosen at random what is the probability of getting heads then a number less than 4
Darya [45]
The probability of getting heads on a coin toss is 0.5
The probability of choosing a number <u>less</u> than four is 3/10 (1,2,3)

Therefore, the probability of getting heads <u>and</u> choosing a number less than four is:
=  \frac{1}{2} (\frac{3}{10}) = \frac{3}{20} = 0.15

Hope this helps!

Mrac [35]
For this case we can model the problem as a rectangle triangle.
 We have:
 Length of the sides of the triangle.
 We want to find:
 Length of the hypotenuse.
 Using the Pythagorean theorem we have:
 d ^ 2 = 2 ^ 2 + 2 ^ 2&#10;
 d =  \sqrt{2 ^ 2 + 2 ^ 2} &#10;&#10;d =  \sqrt{4 + 4} &#10;&#10;d =  \sqrt{8} &#10;&#10;d =  2\sqrt{2} &#10;
 Answer:
 
She is:

Mary has 15 points with the total value of $1.75 if the coins are nickels and quarters how many of each kind are there
torisob [31]

Answer:

The number of nickel coins is 10 and the number of quarter coins is 5

Step-by-step explanation:

<u><em>The correct question is</em></u>

Mary has 15 coins with the total value of $1.75 if the coins are nickels and quarters how many of each kind are there

Let

x ----> the number of nickel coins

y ----> the number of quarter coins

Remember that

1\ nickel=\$0.05

1\ quarter=\$0.25

we know that

Mary has 15 coins

so

x+y=15 -----> equation A

The total value of the coins is $1.75

so

0.05x+0.25y=1.75 ----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (10,5)

therefore

The number of nickel coins is 10 and the number of quarter coins is 5
