Answer:

The probability you will get a head at least once is 50%.

Step-by-step explanation:

Since the question is asking about the probability you will get, we can assume we’re answering based on theoretical probability. This type of probability is based on logic.

A coin always has two sides, one with head and the other with tails. So we can easily represent this as half and half. 1/2 as a fraction. 0.5 as a decimal. 50% as a percent. This means that P(H) will be equal to any one of these as they are all the same. The same can be said for the probability that a head does not appear, in other words, a tail appears. The reason being that the probability is split evenly between the two. This will again mean that P(T) will equal to any one of those.

So, A = 50% and B = 50%. The probability you will get a head at least once is 50%.

Answer: 600 bushels of 10% alcohol content and 400 bushels of 15% alcohol content.

Step-by-step explanation:

Let we add x quantity of 10% of alcohol content and y quantity of 15% alcohol content for making 12% of alcohol content mixture.

Then according to the question, 10% of x + 15 % of y = 12% of 1000

⇒ 0.1x + 0.15y = 120

⇒ 10x + 15y = 1200

⇒ 2x +3y = 2400 -------- (1)

And, x + y = 1000

⇒ 2x + 2y = 2000 ---------(2)

Equation 1) - equation 2)

We get y = 400

By putting the value of y in equation 1),

⇒2x + 1200 = 2400

⇒ 2x = 1200

⇒ x = 600

Thus, he needs to mix 600 bushel of 10% of alcohol content with 400 bushels of 12% of alcohol content for getting 1000 bushels of 12% of alcohol content.

The perimeter of rectangular park is 450m.the length of the sides is in the ratio 3:2.find the area of the rectangle

matrenka [14]

Answer: 12,150 m²

Step-by-step explanation:

The ratio is 3:2 which means

Length (L) = 3x

Width (w) = 2x

Perimeter (P) = 2L + 2w

450 = 2(3x) + 2(2x)

450 = 6x + 4x

450 = 10x

45 = x

L = 3x w = 2x

= 3(45) = 2(45)

= 135 = 90

Area (A) = L × w

= 135 × 90

= 12,150

The sum of two consecutive even numbers is 206. What is the value of the smallest number?

lesya692 [45]

Answer:

102

Step-by-step explanation:

Since we know that the numbers are two consecutive even numbers, we can write an equation like this where n represents the 2 numbers.

n + (n+2) = 206

Simplify the left side:

n + (n+2) = 206 -----> 2n+2 = 206

Subtract 2 from both sides:

2n = 206-2 -----> 2n = 204

Now divide 204 by 2:

n = 204/2 -----> n = 102
