Zigmanuir [339]3 years ago

Answer:

step by step as shown

Step-by-step explanation:

f(x) = x²-1

f(5) = 5² - 1 = 24

f⁻¹(x)

y = x²-1

x = y² - 1    swap x and y

y² = x+1   ... x+1 ≥ 0      x≥-1

y = √x+1

f⁻¹(x) = √x+1

f⁻¹(8) =√8+1 = √9 = 3

Al terminar una obra tres albañiles cobran $16800 y se dividen el dinero a razón 5:7:9. Calcular cuánto dinero le corresponde a
NNADVOKAT [17]

Answer:

$4000, $5600 and $7200

Step-by-step explanation:

Let the money be 5x,7x and 9x.

Total collection of money is $16,800

ATQ,

5x+7x+9x=$16,800

21x=$16,800

x=\dfrac{16800}{21}\\\\x=\$800

So, the values are :

5x=5(800) = $4000

7x=7(800) = $5600

9x=9(800) = $7200

Answer: Hence,  the probability that, out of the next 5 customers, 4 or more will use a coupon is:

                 1/3

Step-by-step explanation: Total 15 trials were recorded as follows:

43454   24511   55555  43453     55315    25215    32235      43311      11154  13342   42514    13223      44215   45313  13324

Now, we are asked to find the probability that, out of the next 5 customers, 4 or more will use a coupon.

We know that probability is the ratio of number of favorable outcomes to the total number of outcomes.

 Hence, number of favorable outcomes are: 5

(32235    43311   13342    13223   13324  )

Total number of outcomes are: 15

( Since 15 trials were performed)

Hence, Probability is:  5/15 = 1/3

 Hence, the answer is: 1/3
