A ball is hurled in the air such that its horizontal (x) and vertical (y) shifts are given by the functions x(t) = 20t and y(t)

Viefleur [7K]

x(t) = 20t

y(t) = 40t - 5t^2

Since we are only interested in comparing the two at time t = 5 seconds, we plug in 5 everywhere we see the variable t and then compare x and y

x(5) = 20(5) becomes x(5) = 100

y(5) = 40(5) - 5(5)^2 becomes y(5) = 200 - 125 and then y(5) = 75

The ratio of y to x can be expressed as: y/x, so we can say the ratio is equal to 75/100 or 0.75

Answer: 0.75

Based on a survey, assume that 38% of consumers are comfortable having drones deliver their purchases. Suppose that we

Maslowich

Answer:

$n = 4$

$x = 2$

$p = 38\%$

$q = 62\%$

Step-by-step explanation:

Required

Find n, x, p and q

n always represent the population surveyed;

So:

$n = 4$

x represents the sample from the population

So:

$x = 2$

p always represents the given proportion

$p = 38\%$

Solving for q

$p + q = 1$

$q = 1 - p$

$q = 1 - 38\%$

$q = 62\%$
