Answer:

<h2>a) center (2, -3)</h2><h2>b) radius r = 3</h2><h2>c) in the attachment</h2>

Step-by-step explanation:

The standard form of an equation of a circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have:

(x-2)^2+(y+3)^2=9\\\\(x-2)^2+(y-(-3))^2=3^2

a) center (2, -3)

b) radius r = 3

c) in the attachment

Can you please help me translate the argument into symbolic form?
Alecsey [184]

Let p be: John goes to the beach

Let q be: He will go surfing.

Then in symbolic form, the argument becomes:

\begin{gathered} p\Rightarrow q \\ p \\ ----------- \\ \therefore q \end{gathered}

p ⇒ q

p

---------------------

∴ q

An argument is valid if the conjuction of the premises implies the conclusion.

p | q | p ⇒ q | (p ⇒ q) ∧ p | [(p ⇒ q) ∧ p] ⇒ q

---------------------------------------------------------------------\

F | F | T | F | T

F | T | T | F | T

T | F | F | F | T

T | T | T | T | T

The table above shows that the argument is a tautology.

Hence, the argument is valid

Bob's average golf score at his local course is 93.6 from a random sample of 34 rounds of golf. Assume that the population stand
xxMikexx [17]

Answer:

a. (92.4, 94.8)

Step-by-step explanation:

Given that:

Mean (m) = 93.6

Standard deviation (σ) = 4.2

Sample size (n) = 34

α = 90%

Confidence interval around sample mean :

Mean ± Zstatistic * s/√n

Z0.90 = 1.645 (Z probability calculator)

s / √n = 4.2 / √34 = 0.7202940

Lower limit = 93.6 - (1.645 * 0.7202940) = 92.41511637 = 92.4

Upper limit = 93.6 + (1.645 * 0.7202940) = 94.78488363 = 94.8
