The correct true statement is the swimmer comes back up 9 seconds after the timer was started.

<h3>Maximum height of a function</h3>

The maximum height of a function is the point where the velocity the body is zero.

Given the function that represent the height of the swimmer as h(t)=t^2−12t+27

If the velocity of the function is zero, hence;

h'(t) = 2t - 12

0 = 2t - 12

2t = 12

t = 6secs

Substitute t = 6 into the function as shown:

h(6) = 6^2−12(6)+27

h(6) = 36 - 72 + 27

h(6) = -36 + 27

h(6) = -9 feet

Hence the correct true statement is the swimmer comes back up 9 seconds after the timer was started.

Part II: Find the angle O in radians, (2 points)

Savatey [412]

The circle has radius 6 feet, so its total circumference is 2π • (6 ft) = 12π ft.

As an arc, the complete circle corresponds to a central angle of 2π radians. So the red arc corresponds to a central angle θ such that

θ / (15 ft) = (2π rad) / (12π ft)

Then

θ = (15 ft) • (2π rad) / (12π ft) = 15/6 rad = 2.5 rad

Suppose that a particular candidate for public office is in fact favored by 48% of all registered voters in the district. a poll

Nutka1998 [239]

Given that a particular candidate for public office is in fact favored by 48% of all registered voters in the district, thus p = 0.48

If a polling organization will take a random sample of 550 voters, i.e. n= 550.

The approximate probability that p̂ will be greater than 0.5 is given by:

$P(\hat{p}\ \textgreater \ 0.5)=1-P(\hat{p}\leq0.5) \\ \\ =1-P\left(z\leq \frac{0.5-0.48}{\sqrt{ \frac{0.48(1-0.48)}{550} }} \right) \\ \\ =1-P\left(z\leq \frac{0.02}{\sqrt{ \frac{0.2496}{550} }} \right)=1-P\left(z\leq \frac{0.02}{0.0213} \right) \\ \\ =1-P(z\leq0.9388)=1-0.82609=0.1739$

Therefore, the approximate probability that p̂ will be greater than 0.5, causing the polling organization to incorrectly predict the result of the upcoming election is 0.1739.

geometry question(s) on triangle similarity, please help, i’d really appreciate it! image is included.

Sergio [31]

1. D. The triangles have two given sides with an included angle, so the postulate would be SAS.

2. A. The triangles have three given sides, so the postulate would be SSS.
