Answer:

The probability of cured people in who took the remedy is 8/9.

Step-by-step explanation:

Success rate of the cold remedy = 88%

The number of people who took the remedy = 45

Now, 88% of 45 = \frac{88}{100}  \times 45 = 39.6

and 39.6 ≈ 40

So, out of 45 people, the remedy worked on total 40 people.

Now, let E: Event of people being cured by cold remedy

Favorable outcomes = 40

\textrm{Probability of Event E}  = \frac{\textrm{Total number of favorable outcomes}}{\textrm{Total outcomes}}

or, \textrm{Probability of people getting cured}  = \frac{\textrm{40}}{\textrm{45}}  = \frac{8}{9}

Hence, the probability of cured people in who took the remedy is 8/9.

What is the zero slope
Mars2501 [29]
It's the first one because all the y's are the same number. That means that when you graph the chart you would get a horizontal line. Horizontal lines on graphs always have a slope of zero....unlike a verticals slope is undefined.

Gnoma [55]

Answer:

The probability is 0

Step-by-step explanation:

Since proportion of time spent on mowing will be 200/400 = 0.5, there will be no chance that the true proportion of time spent mowing is exactly equal to the sample proportion. Where true proportion is 200 and sample is 400 . So the probability is 0.

if a projectile is launched with an intial velocity of 13 meters per second, what angle is required to achieve a range of 15 met
ratelena [41]

Answer:

30° or 60°

Step-by-step explanation:

Range of a projectile on level ground is:

R = v₀² sin(2θ) / g

Given R = 15 m and v₀ = 13 m/s:

15 m = (13 m/s)² sin(2θ) / (9.8 m/s²)

sin(2θ) = 0.870

2θ = 60.4° or 119.6°

θ = 30.2° or 59.8°

Rounded, the launch angle required is either 30° or 60°.
