The theoretical probability of getting heads or tails is 1/2 the time.

1/2 of 150 = 75

 So theoretically you would get 75  heads and 75 tails.

The experiment got 84 heads, which is greater than 75, so it would be higher than the theoretical probability.

The answer is : <span>It is 6% higher than the theoretical probability.</span>

The equation y=0.5x+40 represents the monthly cost y in dollars of Lesley's cell phone, where x is the of talk minutes over 750
Firdavs [7]
You already have the equation given which is <span>y=0.5x+40. To graph, you just have to replace random values of x to determine the corresponding values of y. Plot these points and connect them. The graph is shown in the attached picture. As you can observe, the range starts from y=40. This is because the y-intercept is 40. So, you don't have to show the y-values below because it would just minimize your linear graph.</span>

A company manufactures cell phones. In August, a random sample of 125 cell phones was inspected, and 3 phones were found to be d
german

Answer:

192

Step-by-step explanation:

To find how many phones are expected to be defective, we need to represent the values in a fraction.

\dfrac{x}{8000}=\dfrac{3}{125}

x = number of defective phones

Now we can solve this using algebra.

To get the value of x we need to multiply both sides by 8000 to leave x alone.

x=\dfrac{3}{125}(8000)

x=0.024(8000)

x=192

So around 192 cell phones are expected to be defective out of 8000 phones.
