Ivan and jeff buy a package of 8 pen for 4.00. ivan want 5 of the pen. how many should ivan pay?

inysia [295]

Answer:

$2.50

Step-by-step explanation:

Let's set up a proportion using the following setup.

price / pens = price / pens

We know that it costs $4.00 for 8 pens.

$4.00 / 8 pens = price / pens

We don't know how much it costs for 5 pens. Therefore, we can say it costs $x for 5 pens.

$4.00 / 8 pens = $x / 5 pens

4/8=x/5

We want to solve for x (the cost for 5 pens). Therefore, we must get x by itself on one side of the equation. x is being divided by 5. The inverse of division is multiplication, so multiply both sides of the equation by 5.

5*(4/8)=(x/5)*5

5*(4/8)=x

5*0.5=x

2.5=x

x= $2.50

Ivan should pay $2.50 for 5 pens.

We have the following expression given:

$(4y^3+28y^2)+(y+7)$

We can start selecting as common factor 4y^2 and we got:

$4y^2(y+7)+(y+7)$

Now we can select y+7 as common factor and we got:

$(y+7)\left\lbrack 4y^2+1\right\rbrack$

So then our final answer would be:

$(y+7)(4y^2+1)$

xz_007 [3.2K]

Answer:

0.549 or 54.9%

Step-by-step explanation:

This is a binomial distribution (Bernoulli's experiment), where the probability of “success” (selecting a battery with acceptable voltage) is 0.9 and the probability of “failure” is 0.1

So, the probability of selecting at least 14 acceptable batteries out of 15 is

$\large C(15,14)(0.9)^{14}(0.1) + C(15,15)(0.9)^{15}$

where <em>C(n, m) are combinations of n elements taken m at a time</em>.

C(15,14) = 15

C(15,15) = 1

so, the probability we are looking for is

$\large 15*(0.9)^{14}0.1+(0.9)^{15}=0.3431+0.2058 = 0.549 = 54.9\%$
