Answer:

x = 45

Step-by-step explanation:

Straight line has 180 degrees; so if you add all the angles up:

2x + x + x = 180

4x = 180

x = 45 degrees

Rate (R) = 25/3 Interest = Rs. 350 (d) Principal = Rs. 2400 Find the time (t)

julia-pushkina [17]

Answer:

The value of t is 1.75 years.

Step-by-step explanation:

Given that simple interest formula is I = (P×R×T)/100. So you have to substitute the following values into the formula :

$i = \frac{prt}{100}$

$let \: i = 350,p = 2400,r = \frac{25}{3}$

$350 = \frac{2400 \times \frac{25}{3} \times t }{100}$

$350 = \frac{20000t}{100}$

$350 \times 100 = 20000t$

$20000t = 35000$

$t = 35000 \div 20000$

$t = 35 \div 20$

$t = 1.75 \: years$

Organizers of an outdoor summer concert in Toronto are concerned about the weather conditions on the day of the concert. They wi

Kobotan [32]

Answer:

The value of the expected profit from the concert is 8,910

Step-by-step explanation:

Profit on a clear day X₁ = 36,000 with 13% probability.

i.e X₁ = 36000

P(X₁) = 0.13

Profit on a cloudy day = 17,000 with 39% probability.

i.e X₂ = 17000

P(X₂) = 0.39

else,

loss of 5,000 if it rains with the probability of 48%.

i.e X₃ = 5000

P(X₃) = 0.48

The value of the expected profit from the concert is obtained as follows

Expected Value = (36,000*0.13) + (17,000*0.39) - (5,000*0.48)

= 4,680 + 6,630 - 2,400

= 8,910
