Use the distributive property to expand: x^-3 y^0(x^2-3x^5 y^4)

1 answer:

4 0

${x}^{ - 3} {y}^{0} ( {x}^{2} - 3 {x}^{5} {y}^{4} ) \\ = {x}^{ - 3} (1) ( {x}^{2} - 3 {x}^{5} {y}^{4} ) \\ = {x}^{ - 1} - 3 {x}^{2} {y}^{4}$

The mean amount spent by a family of four on food is $500 per month with a standard deviation of $75. Assuming that the food cos

Alexeev081 [22]

Answer:

$z=\frac{x- \mu}{\sigma}$

And replacing we got:

$z=\frac{425-500}{75}= -1$

And we can calculate this probabilit using the normal standard distribution or excel and we got:

$P(z$

Step-by-step explanation:

If we define the random variable of interest "the amount spent by a family of four of food per month" and we know the following parameter:

$\mu = 500, \sigma = 75$

And we want to find the following probability:

$P(X$

And we can use the z score formula given by:

$z=\frac{x- \mu}{\sigma}$

And replacing we got:

$z=\frac{425-500}{75}= -1$

And we can calculate this probabilit using the normal standard distribution or excel and we got:

$P(z$

The area of a rectangular wall of a barn is 96 square feet. Its length is 10 feet longer than the width. Find the length and wid

Bad White [126]

(x)(10+x)=96
$10x + {x}^{2} = 96$
${x}^{2} + 10x - 96 = 0$
(x-6)(x+16)=0

x=6,-16

negative can't be an answer this the answer is 6+10= 16 ft
