Answer:

B. x > 3 or x < −3

Step-by-step explanation:

We are given that,

p: x < −3

q: x > 3

Since, we know that,

The symbol v is known as 'disjunction', which is in other words represented by 'union', 'or'.

Thus, 'p ∨ q' means 'either p holds or q holds'.

Hence, we get,

'p ∨ q' is represented by 'either x <-3 or x > 3'.

i.e. 'p ∨ q' is represented by 'either x > 3 or x <-3'.

Thus, option B is correct.

A square pool has a side length of x feet. a uniform border around the pool is 1 foot wide. the total area of the pool and the b

Alex73 [517]

----------------------------------------
Define x:
----------------------------------------
Let x be the length of the pool.

Length of the pool and its border = x + 1 + 1
Length of the pool and its border = x + 2

----------------------------------------
Given area = 361 ft², find x:
----------------------------------------
(x+2)² = 361
x+ 2 = √361
x + 2 = 19
x = 19 - 2
x = 17

----------------------------------------
Find Length of the pool:
----------------------------------------
Length of the pool = x = 17 feet

----------------------------------------
Find Area of the pool:
----------------------------------------
Area = 17 x 17
Area = 289 ft²

------------------------------------------------------------
Answer: Area of the pool = 289 ft²
------------------------------------------------------------

A researcher collects data on the number of times race horses are raced during their careers. The veterinarian finds that the av

vesna_86 [32]

Answer:

95% confidence for µ, the average number of times a horse races

(12.493 , 18.107)

Step-by-step explanation:

Explanation:-

The veterinarian finds that the average number of races a horse enters is 15.3

The mean of the sample x⁻ = 15.3

Given standard deviation of the sample 'S' = 6.8

Given sample size 'n' = 25

Degrees of freedom = n-1 =25-1 =24

The tabulated value 't' = 2.064 at two tailed test 0.95 level of significance

95% confidence for µ, the average number of times a horse races

$(x^{-} - t_{\alpha } \frac{S}{\sqrt{n} } , x^{-} + t_{\alpha }\frac{S}{\sqrt{n} } )$

$(15.3- 2.064 \frac{6.8}{\sqrt{25} } , 15.3 + 2.064\frac{6.8}{\sqrt{25} } )$

(15.3 - 2.80704 ,15.3 +2.80704)

(12.493 , 18.107)

Conclusion:-

95% confidence for µ, the average number of times a horse races

(12.493 , 18.107)

Studies show that the average American has $4,878 in credit card debt with an average interest rate of 12.78% compounded monthly

Molodets [167]

Answer:

$62,005.34

Step-by-step explanation:

If the interest rate is 12.78% compounded monthly, we can use the formula a = p(1+r/n)^nt

where a is the final value to be paid, p is the inicial value, r is the interest rate, n is the number of months in a year and t is the time in years

So, the total debt will be:

y = 4878 * (1+0.1278/12)^240 = $62,005.34
