Answer:

(c) 45x³y

Step-by-step explanation:

Terms of a polynomial expression are separated by + or - signs. If there is only one term, there is no need to separate terms with such signs.

<h3>One term</h3>

The one-term expression is ...

45x³y

__

<em>Additional comments</em>

If the coefficient of a one-term expression is negative, there will be a leading minus sign. There won't be another term on the other side of that sign.

The given expressions appear to suffer from poor editing. Ordinarily, exponents are rendered using a superscript font, as the 3 is in the first expression. However, the second term of that expression is 1x2, which we understand to be 1x². If the 2 were intended as a multiplier, rather than an exponent, we would expect it to be combined with the coefficient 1 in that term to give (xy)³ -2x.

It is this assumption that leads us to write 45x3y as 45x³y. If that is not the intention of the given expression, it could be simplified to 135xy.

Ordinarily, if an exponent is not rendered in superscript font, we expect it to be identified by the caret (^) operator, as in 45x^3y.

Answer:

Step-by-step explanation:

Using the experimental probability, first we have to find total amount paint then to find the amount of good quality forever paint we have to subtract the amounts of other paints from total amount.

Let x represents the amount of good quality forever paint sold.

Total amount of paint $=48+45+35+39+33+x=200+x$ ...(i)

Experimental probability of paint sold will be better quality durable paint is

$P=\dfrac{\text{Amount of better quality durable paint}}{\text{Amount of total paint}}$

$P=\dfrac{45}{\text{Amount of total paint}}$

It is given that experimental probability of paint sold will be better quality durable paint is $\frac{9}{50}.$

$\frac{9}{50}=\dfrac{45}{\text{Amount of total paint}}$

$\text{Amount of total paint}=\dfrac{45\times 50}{9}$

$\text{Amount of total paint}=250$ ...(ii)

From (i) and (ii), we get

$200+x=250$

$x=250-200$

$x=50$

Therefore, 50 gallons good quality forever paint is sold.

Answer: 505

Step-by-step explanation:

The formula to find the sample size n , if the prior estimate of the population proportion (p) is known:

$n= p(1-p)(\dfrac{z}{E})^2$ , where E= margin of error and z = Critical z-value.

Let p be the population proportion of crashes.

Prior sample size = 250

No. of people experience computer crashes = 75

Prior proportion of crashes $p=\dfrac{75}{250}=0.3$

E= 0.04

From z-table , the z-value corresponding to 95% confidence interval = z=1.96

Required sample size will be :

$n=0.3(1-0.3)(\dfrac{1.96}{0.04})^2$ (Substitute all the values in the above formula)

$n= (0.21)(49)^2= 0.21\times2401$

$n= 504.21\approx505$ (Rounded to the next integer.)

∴ Required sample size = 505
