3. This was spun 50 times, and it landed on yellow 6 times. Therefore, it won't land on yellow all but 6 times. P(not yellow) is 44/50, or 22/25.
4. If 50 students are asked, and 7 have a dog, then the probability is 7/50. We can use a proportion to find the equivalent of 7/50 with a denominator of 1400, because that is how many people are at the school. 7/50=x/1400. 50x=9800. x=196

Does anyone know how to do this??

Answer:

  y > 11/2

Step-by-step explanation:

This is solved the same way a 3-step equation is solved.

<u>Step 1</u>: subtract the smaller variable term from both sides.

  4y -2y +3 > 2y -2y +14

  2y +3 > 14

<u>Step 2</u>: subtract the constant with the variable term.

  2y +3 -3 > 14 -3

  2y > 11

<u>Step 3</u>: divide by the coefficient of the variable.

  2y/2 > 11/2

  y > 11/2

_____

<em>Additional comment</em>

By choosing to subtract the smaller variable term in the first step (regardless of which side of the inequality it is on), we ensure that the remaining variable coefficient is positive. That means we can do step 3 without worrying about changing the direction of the inequality symbol, because we're dividing by a positive number.

The circumference of a circle varies directly as its diameter. When the diameter of a circle is 6 inches the circumference is 18
qwelly [4]

Answer:

The diameter is 2

Step-by-step explanation:

We can use a ratio to solve

6              x

-------  = --------------

18.84      6.28

Using cross products

6 * 6.28 = 18.84x

Divide each side by 18.84

37.68/18.84 = x

2 =x

drake made 12 out of 30 free throw shots. about how many out of the next 50 free throw shots would you expect him to make?
larisa86 [58]
12/30 X/50 you'd cross multiply and get 30X=600 get 30 away from X which you'd divide 600 by 30 and get 20. drake is expect to make 20 out of 50 free throws
