Consider the following binomial experiment: A newspaper publisher claims that 52% of the people in a certain community read his
AURORKA [14]

Answer:

SD = 8.4932

Step-by-step explanation:

Given

Sample\ Size (n) = 289

proportion, p= 52\%

Required

Determine the standard deviation (SD)

The standard deviation of a binomial distribution is calculated as thus:

SD = \sqrt{np(1-p)}

Substitute values for n and p

SD = \sqrt{289 * 52\% * (1-52\%)}

Convert to decimals

SD = \sqrt{289 * 0.52 * (1-0.52)}

SD = \sqrt{289 * 0.52 * 0.48}

SD = \sqrt{72.1344}

SD = 8.49319727782

SD = 8.4932 --- <em>approximated</em>

<em>Hence, the calculated standard deviation is approximately 8.4932</em>

Daniel kicks a soccer ball and the trajectory is modeled by f(t) =− 16t^2+ 32t .
vagabundo [1.1K]

Answer:

f(1) = 16

Domain: 0 ≤ t ≤ 2

Step-by-step explanation:

Given

f(t) = -16t²+ 32t

Solving (a): f(1)

Substitute 1 for t in f(t)

f(t) =− 16t²+ 32t .

f(1) =− 16 * (1)²+ 32 * 1

f(1) = -16 * 1 + 32

f(1) = -16 + 32

f(1) = 16

Solving (b): The domain

The implication of the given parameter in (b) is that t ≤ 2.

Since t represents time, t can't be negative.

Hence, a reasonable domain is

0 ≤ t ≤ 2
