Determine the whether the sum of 7/8 and 4/9 is closest to 0,1,2,or 3

1 answer:

8 0

Whenever you add fractions it means you need a common denominator. The quickest way to find this number is to multiply the two denominators together (in this case 8 and 9).
So your new fractions are 63/72 and 32/72. When you add those you get 95/72.
Next simply divide the two numbers to get a decimal, so here we get: 1.31944...
So this number is closer to 1
Hope that helps!!

6x -2x3 + 10x+2x3+7x4 simply

zmey [24]

$(((6x-(2*(x3)))+10x)+(2*(x3)))+7x4 \\ \\ Then \ we \ simplify \ it \ down \ more. \\ \\ (((6x-(2*(x^3)))+10x)+2x^3)+7x^4 \\ \\ then \ we \ would \ then \ pull \ out \ the \ like \ factors . . . . \\ \\ 7x^4 + 16x = x * (7x^3 + 16) \\ \\$

Your final answer: $\boxed{\bf{ x *(7x^3 + 16)}}$

4 cups of dried fruit would need to be taken out to keep the original ratio.

Given:
30 cups of trail mix.
ratio of nuts to dried fruit is 3 to 2.

3:2 = 6:x
3x = 2*6
3x = 12
3x/3 = 12/3
x = 4 cups of dried fruits

Jorgensens, an Electronics

pshichka [43]

Answer: 0.3399

Step-by-step explanation:

The binomial probability distribution formula to find the probability of getting success in x trial:-

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where n is the number of trials and p is the probability of getting success in each trial.

Given : Jorgensens received a shipment of 12 DVD Players. Shortly after arrival the manufacturer called to say that that he had accidentally shipped five defective units with the shipment.

i.e. The proportion of the defective units : $p=\dfrac{5}{12}\approx0.417$

Also, Mr. Jorgensen pulled ten of the units and tested two of them.

For n=2, the probability that neither of them was defective:-

$P(x=0)=^{2}C_0(0.417)^0(1-0.417)^{2}\\\\=(1)(1)(0.583)^{2}\ \ \ [\text{ Since}^nC_0=1]\\\\=0.339889\approx0.3399$

Hence, the probability that neither of them was defective = 0.3399
