The position of an object moving along a straight line for

NikAS [45]

Answer:

at 2/3 seconds

Step-by-step explanation:

S1(t) = t³ + 2

Average speed, dS1/dt = 3t²

S2(t) = t²

Average speed, dS2/dt = 2t

The distance between the objects is

dS1/dt - dS2/dt

= 3t² - 2t

The time the distance between the two object is at minimum is when the distance is 0

That is, when

3t² - 2t = 0

t(3t - 2) = 0

t = 0 or 3t - 2 = 0

t = 0 or t = 2/3

(1 point) A random sample of 600 movie goers in Flagstaff found 252 movie goers who had bought popcorn on their last visit. Find

garik1379 [7]

<u>Answer-</u>

A 95% confidence interval for the true percent of movie goers is 36.41% to 44.25%

<u>Solution-</u>

Given,

n = 600 (sample size)

x = 252 (number of people who bought)

Confidence interval = 95%, so z = 1.96

We know that,

$\mu = M\pm Z(SE)$

where,

M = sample mean

Z = Z statistic determined by confidence level

SE = standard error of mean

Calculating the values,

$M=\frac{x}{n} =\frac{242}{600} =0.4033$

$Z=1.96$ from the tables

$SE=\sqrt{\frac{M\times (1-M)}{n}}$

$\Rightarrow SE=\sqrt{\frac{0.4033\times (1-0.4033)}{600}}=0.02$

Putting all the values in the formula,

$\mu = M\pm Z(SE)$

$\mu = 0.4033\pm 1.96(0.02)$

$=0.4033\pm 0.0392$

$=0.4425, 0.3641$

$= 44.25\%,36.41\%$
