there are 40 cards in a bag each bears a number from 1 to 40 one card is drawn at random what is the probability that the card b

AVprozaik [17]

Answer:

Given :

There are 40 cards in a bag .

To Find :

Probability of getting a multiple of 5 .

Solution :

\longmapsto\tt{Total\:Outcomes=40}⟼TotalOutcomes=40

\longmapsto\tt{Favourable\:Outcomes=8}⟼FavourableOutcomes=8

= 5 , 10 , 15 , 20 , 25 , 30 , 35 ,40 .

\longmapsto\tt\bf{Probability=\frac{No.\:of\:Fav.\:Outcomes}{Total\:No.\:of\:Outcomes}}⟼Probability=

TotalNo.ofOutcomes

No.ofFav.Outcomes

\longmapsto\tt{\cancel\dfrac{8}{40}}⟼

\longmapsto\tt\bf{\dfrac{1}{5}}⟼

So , The Probabilty of getting a multiple of 5 is 1/5 ...

Probability :

It is defined as chances of occuring or happening of an event.

Probability of an event can never be negative.

Probability of an event always lies between 0 and 1.

It is given that 2(3 + x) = 6 + 2x. This is an example of the ___________ property. A) associative B) commutative C) distributiv

nevsk [136]

Keywords:

Expression, simplified, property, distributive

For this case we have an expression of the form $2 (3 + x)$ that was simplified to the expression $6 + 2x$ . They ask us to indicate which property was used to simplify the expression.

We have that, by definition, the distributive property states that:

$a (b + c) = ab + ac$

So:

$2 (3 + x) = 2 * 3 + 2 * x = 6 + 2x$ is an example of the distributive property.

Answer:

This is an example of the property distributive

A football player punts a ball. The path of the ball can be modeled by the equation y = –0.004x2 + x + 2.5, where x is the horiz

Galina-37 [17]

The answer is 252.5 ft

y = –0.004x² + x + 2.5
Let's take y = 0 and we'll get the quadratic equation:

–0.004x² + x + 2.5 = 0
The general formula for quadratic equation is:
ax² + bx + c = 0

a = -0.004
b = 1
c = 2.5

$x_{1,2} = \frac{-b+/- \sqrt{ b^{2}-4ac} }{2a} =\frac{-1+/- \sqrt{ 1^{2}-4*(-0.004)*2.5} }{2*(-0.004)} = \frac{-1+/- \sqrt{1+0.04} }{-0.008} = \\ 
=\frac{-1+/- \sqrt{1.04} }{-0.008} = \frac{-1+/-1.02}{-0.008}$

$x_1=\frac{-1+1.02}{-0.008} = \frac{0.02}{-0.008} = -2.5 \\ 
x_2=\frac{-1-1.02}{-0.008} = \frac{2.02}{-0.008} = 252.5$

Since distance cannot be negative (x1), the correct answer is x2 = 252.5 ft

Melanie uses 8.1 pints of blue paint and white paint to paint her bedroom walls. 2/5 of this amount is blue paint, and the rest

attashe74 [19]

Answer:

4.86

Step-by-step explanation:

Melanie uses 8.1 pints of blue paint and white paint for her bedroom

2/5 of this amount is blue paint

Therefore the amount of white paint can be calculated as follows

= 2/5

= 0.4×100

= 40%

60/100 × 8.1

= 0.6 × 8.1

= 4.86

Hence 4.86 pints of white paint will be used to paint the bedroom
