Answer:
The probability that no one in a family of five will be hospitalized in a year is 0,2373
Step-by-step explanation:
Let p denote the probability of being hospitalized during a year,
Then p=0.25
And p' the probability of not being hospitalized during a year is 1-p
Thus p' = 1-p = 1-0.25 = 0.75
The probability that no one in a family of five will be hospitalized in a year is equal to . That is
= ≈ 0,2373
The algebraic expression for the given problem is:
Speed of airplane = 2x + 20
In mathematics, an expression is a combination of numbers, symbols, and operators (such as +, −, ×, ÷, ^) used to represent a quantity or a mathematical relationship between quantities.
" An airplane went 20 miles an hour faster than twice the speed of a car that ran x miles an hour"
The algebraic expression for the given problem is:
Speed of airplane = 2x + 20
Where x is the speed of the car in miles per hour.

Answer: B
Because you can eliminate the ones that don’t have an inequality symbol so that leaves you with B and D and the 20 should be on the right by itself since that is the constant we are given and it’s not altered in the question
Answer:
The expression is equal to 12.
Step-by-step explanation:
First of all, compute the parenthesis.
18 / 6 = 3
Now, replace 18/6 with 3 in our expression.
Next, compute the multiplication.
-12 * 3 = -36
Again, we'll replace that multiplication with negative 36:
Since subtracting a negative number is the same as adding a positive number:
Compute the addition:
Answer: The expression is equal to 12.
Answer:
12
Step-by-step explanation:
Given : ABC
To prove that M<1 + m<2 + m<3 = 180, we need to use the given information that ABC is a triangle.
In a triangle, the sum of the interior angles is always equal to 180 degrees.
Let's label the angles of triangle ABC as follows:
Angle A as M<1
Angle B as m<2
Angle C as m<3
Using the given information, we can rewrite the equation as:
M<1 + m<2 + m<3 = A + B + C = 180
This equation holds true because it is a fundamental property of triangles. Therefore, the statement is proven.
