Readme [11.4K]

Answer:

last year it was 80k

Step-by-step explanation:

Population increases by 5% every year

Last year it was 80,000

PRESENT POPULATION

Present population = 80,000 + 5% off 80,000

                               = 80,000 + 5/100 × 80,000

                               = 80,000 + 5 × 800

                               = 80,000 + 4,000

                               = 84,000

AFTER ONE YEAR

After this , the population again increases by 5%

Population = 84,000 + 5% off 84,000

                 = 84,000 + 5/100 × 84,000

                 = 84,000 + 5 × 840

                 = 84,000 + 4,200

                 = 88,200

ANSWERS

The population of present year is 84,000

After one year , the population becomes 88,200

Hope it helps :-)

1 Suppose you choose at random a real number X from the interval [2, 10]. (a) Find the density function f(x) and the probability
antoniya [11.8K]

Answer:

Step-by-step explanation:

Given that you choose at random a real number X from the interval [2, 10].

a) Since this is a contnuous interval with all number in between equally likely

E = probability for choosing a real number is U(2,10)

pdf of E is \frac{1}{8}

b) P(X>5) = \int\limits^10_5 {1/8} \, dx = \frac{5}{8}

P(5

For

x^2-12x+35 >0\\(x-5)(x-7)>0\\x7

P(X<5 or x>7) = 1-P(5<x<7)

= \frac{3}{4}
