2. A medical study tests a new cough medicine on 4250 people. It is effective for 3982 people. What is the experimental probabil

Nutka1998 [239]

Answer:

For a 9000 people, the approximate number of people for whom the medicine will be effect is 8432 people

Step-by-step explanation:

Here we have probability is given by

Probability = $\frac{Number\, of \, Success}{Number\, of \, Trials}$ Where:

Number of success = 3982 and

Number of trials = 4250. therefore;

$Probability \, of \, Success = \frac{3982}{4250} = \frac{1991}{2125}$

Therefore, when the medicine is used on 9000 people, the approximate number of people for whom the medicine will be effect is given by;

$\frac{1991}{2125} = \frac{x}{9000} \rightarrow x \times2125 = 1991 \times 9000\\x = \frac{1991 \times 9000}{2125} = \frac{143352}{17} = 8432\frac{8}{17}$

or ≈ 8432 people.

24x-45y=34x<br><br><br><br><br><br><br>(rp)<br><br><br><br><br><br>have a great day

24x-45y=34x

To solve for y, subtract 24x:
-45y=10x

Divide by -45:
y=-10/45x

Reduce:
y=-2/9x

To solve for x, subtract 24x:
-45y=10x

Divide by 10:
-45/10y=x

Reduce:
-9/2y=x

Step-by-step explanation:

Given that:

Surface Area of larger pyramid = 539 ft²

Scale factor of the smaller pyramid = 1/7

Tbe surface area of the smaller pyramid will be :

Scale factor * surface area

1/7 * 539ft²

= 539 ft² / 7

= 77 ft²
