A school has 320 girls and 250 boys the probability of a girl being left handed is 0.2 the probability of a boy being left handed is 0.1 estimate the amount of left handed people there are in the school

Answers

Answer 1

320 girls & 250 boys

0.2 probability     0.1 probability

320 x 0.2 = 64

250 x 0.1 = 25

64 + 25 = 89

There are approximately 89 students in the school that are left-handed.

Answer 2

Answer

89% of the people are left handed

Step-by-Step Explanation

To find this you have to first do 320 x 0.2

320 x 0.2= 64

To find it for boys you have to do 250 x 0.1.

250 x 0.1= 25

SO, the answer is 89%. 64% of girls and 25% of boys

Hope i helped :D

Goodluck everybody!

∛2 is the radical part of both ∛54 and ∛128  when the expression are simplified.

What is Number system?

A number system is defined as a system of writing to express numbers.

Let us write the prime factors of 54.

54/2 = 27

When fifty four is divided by 2 we get twenty seven.

27/3=9

Twenty seven divided by three is nine.

9/3=3

So 54 = 2 × 3 × 3 × 3

we know ∛ 3 × 3 × 3 = 3

∛54 = ∛ 3 × 3 × 3×2 = 3∛2

Hence, ∛2 is the radical part of both ∛54 and ∛128  when the expression are simplified.

A scuba diver descends below the surface of a lake at a rate of 12 feet per minute. What integer represents the depth of the diver after 4 minutes?

Answers

Since this scuba diver descends below the surface of a lake at a rate of 12 feet per minute, an integer which represents the depth of the diver after four (4) minutes is 48 feet.

What is the rate of change?

The rate of change can be defined as a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.

Mathematically, the rate of change for the depth covered by this scuba can be calculated by using this formula;

Rate of change = Depth/time

Making depth the subject of formula, we have:

Depth = Rate of change × time

Substituting the given parameters into the formula, we have;

Depth = 12 × 4

Depth = 48 feet.
