Answer:

5 m

Step-by-step explanation:

The volume (V) of a square based pyramid is

V = \frac{1}{3} Ah ( A is the area of base and h the height ), thus

\frac{1}{3} A × 12 = 100, that is

4A = 100 ( divide both sides by 4 )

A = 25

Hence s² = 25 ← s is the side of square base

Take the square root of both sides

s = \sqrt{25} = 5

V = Ab·h : 3

100m³ = Ab·12m : 3

300m³ = Ab·12m

Ab = 300m³/12m

= 25m²

Ab = 25m² = L²

L = √25m²

L = 5m

In a group of 10 people, there are 4 people that have the flu virus. Suppose we pick 3 random persons to test in order to determ
Murljashka [212]

Answer:

Tests is 100% Accurate, so by using the formula of random variable probability.

Step-by-step explanation:

Total number of people = 10

Sample space = p(A) = 10

Number of people that have flu = n(s) = 4

Pick random 3 persons, the possibility that they have flue is n(A) = ?

Let X is the random variable, consisting of number of positive flu test,

Tests is 100% Accurate, so by using the formula of random variable probability, we get

  P(X) = n (A) / n(S)

  P(X)      = ¾, is the probability of having positive flu test

How many even 2-digit positive integers can be written using the numbers 2, 4, 5, and 8?
BartSMP [9]

Answer:

12

Step-by-step explanation:

To have an even integer the number's endian has to be an even number. Consider the 2-digit positive number like _ _ and place the number of possible options out of four total options in each blank space. We have 3 even options, so we can fill the endian blank like this _ <u>3</u>

Since the first digit can be any number, therefor, we have 4 options for the first blank space <u>4</u> <u>3</u>. Just multiply the two numbers and you have the answer.

22, 24, 28, 42, 44, 48, 52, 54, 58, 82, 84, 88

Examine the diagram.
aniked [119]

An outside angle of a triangle is equal to the sum of the two opposite inside angles.

Using the information in the picture, 132 is an outside angle and x and (3x-24) are the two opposite inside angles.

Setting up the equation you would have: 132 = x + (3x-24)

Now solve for x:

132 = x + (3x-24)

Simplify:

132 = 4x -24

Add 24 to both sides:

156 = 4x

Divide both sides by 4:

x = 156/4

x = 39
