A spinner with 4 equal sections (red, blue, green, yellow) is spun 43 times. About how many times would you predict it lands on

Andrews [41]

Answer:

11 times

Step-by-step explanation:

Sample space = {red, green, blue, yellow)

Probability of landing blue in a single spin ;

P(blue) = required outcome / Total possible outcomes

P(blue) = number of blue / sample space

P(blue) = 1/4

Number of spins = 43

Expected number of times it'll land on blue :

P(blue) * number of spins

1/4 * 43 = 10.75

About 11 times

Can I get some help on this math problem

Answer:

$x=3\sqrt{5}$

Step-by-step explanation:

<u>Right Triangles</u>

Right triangles have one of its interior angles with a measure of 90°.

In right triangles the Pythagora's Theorem is satisfied.

Being c the longest side (hypotenuse), a and b the shorter sides (the legs), then:

$c^2=a^2+b^2$

We have modified the image to include some known data. Both triangles are congruent since they share one side, have a right angle, and have the same base length.

This means the value of x can be calculated as the hypotenuse of the triangle 3-6-x:

$x^2=3^2+6^2=9+36=45$

$x=\sqrt{45}=\sqrt{9*5}$

$\boxed{x=3\sqrt{5}}$

How do i solve this

Montano1993 [528]

The answer to this problem is 3 is less than or equal to 17

You solve the problem by subtracting 2 from 5 because you have to solve for X. 5 minus 2 is 3, so you would get 3 if you had the problem.

Hope this helps!
