Find X (2/3 x) (x + 40)

Mathematics
1 answer:
gtnhenbr [62]3 years ago
6 0

The Answer Is X=84

Make an equation for x.

x+40+2/3x=180

x+2/3x=140

Combine like terms.

1 2/3x=140

140/1 2/3 =84

x=84

Identify the probability to the nearest hundredth that a point chosen randomly inside the rectangle is in the triangle. HELP PLE
sashaice [31]

Answer:

0.02

Step-by-step explanation:

we know that

The probability that a point chosen randomly inside the rectangle is in the triangle is equal to divide the area of the triangle by the area of rectangle

Let

x-----> the area of triangle

y----> the area of rectangle

P -----> the probability

P=x/y

<em>Find the area of triangle (x)</em>

A=(1/2)(5)(2)=5\ in^{2}

<em>Find the area of rectangle (y)</em>

A=18*12=216\ in^{2}

<em>Find the probability P</em>

P=5/216=0.02

The diameter of a bacteria colony that doubles every hour is represented by the graph below. What is the diameter of the bacteri
Nady [450]

Do you notice anything strange about those points ?

(0, 1), 
(1, 2), 
(2, 4),
(3, 8).

The y-coordinate of each point is (2) raised to the  power of the x-coordinate.

First point:       x=0,  y=2⁰ = 1
Second point: x=1,  y=2¹ = 2
Third point:      x=2,  y=2² = 4
Fourth point:    x=3,  y=2³ = 8


The equation of the curve appears to be

                               y = 2 ^ x .

So, after 10 hours,  x=10, and  y = 2¹⁰ = 1,024 .

The calculation of the mean of a population and the expected value of the probability mass function of a Random Variable (RV) ar
Zanzabum

Answer: Hello the options related to your question is missing attached below are the missing options.

A.) The probabilities of the RVs may be equal

B.) The sum of the probabilities of the RVs exceed 1

C.) This is an impossible occurrence

D.) The probabilities of the RVs must be equal

E.) None of the above

answer:

The probabilities of the RVs may be equal ( A )

Step-by-step explanation:

Given that the value of the  population mean and the value of probability mass function of a set of random variables are similar

For the Random Variables : 100,200,300,400

The Probability mass function of RV = ( 100 + 200 + 300 + 400 ) / 4

Hence  The probabilities of the RVs may be equal
