The answer: 75 % of 200 miles is 150 miles.
________________________________________________
Explanation:
__________________________________________________
$\frac{x}{100}$ * 200 = 150 ;
__________________________________________________
Solve for "x" ;
_____________________________________
→ Divide each side of the equation by "200" ;
__________________________________________
→ ( $\frac{x}{100}$ * 200) / 200 = 150 / 200 ;
__________________________________________
→ $\frac{x}{100}$ = $\frac{150}{200}$ ;
__________________________________________________
↔ $\frac{150}{200}$ = $\frac{x}{100}$ ;
___________________________________________________
→ (150 ÷ 2) / (200 ÷ 2) = x / 100 ; Solve for "x" ;
_______________________________________________
→ x = 150 ÷ 2 = 75 .

A certain cold remedy has an 88% rate of success of reducing symptoms within 24 hours. Find the probability that in a random sam

Hitman42 [59]

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.

Which is the equation of the parabola?

mestny [16]

Answer:

y = -1/20(x + 3)²

Step-by-step explanation:

<u>Consider the parent function:</u>

y = x²

The graph of the function open up and the vertex is at the origin, the point (0, 0)

Now, if it opens down, it means it is a reflection of the parent function over x axis, hence it has a negative coefficient, the function becomes:

y = -x²

The vertex is shifted to the point (-3, 0). It means the function also translated left by 3 units, the function becomes:

y = -(x + 3)²

<u>Since all the options have 1/20 as a coefficient, our function is:</u>

y = -1/20(x + 3)²

This is option B
