What is the value of the expression x^2y–y+xy^2–x for x=4 and y=0.25?

stepan [7]

Answer:

0 (zero)

Step-by-step explanation:

${x}^{2} y - y + x {y}^{2} - x \\ = {4}^{2} \times 0.25 - 0.25 + 4 \times {0.25}^{2} - 4 \\ = 16 \times 0.25 - 0.25 + 4 \times 0.0625- 4 \\ = 4 - 0.25 + 0.25 - 4 \\ = 0 \\ \\ \purple {\boxed{ \bold{ \therefore \: {x}^{2} y - y + x {y}^{2} - x = 0}}}$

Vlada [557]

When Thanos snaps he wipes out have of the universe. That doesn't mean half of every population on every single planet. That means half of the universe as a whole. This question does not have an exact answer because though its unlikely, it is possible that when Thanos snaps, nobody on Earth dies.

Because of the relatively high interest rates, most consumers attempt to pay off their credit card bills promptly. However, this

Anastasy [175]

Answer:

Step-by-step explanation:

Let X be average interest paid monthly by a bank's Visa cardholders

Given that X is N(28, 8)

In the following to find out probability we convert X to z score and use std normal distribution table

Z = $\frac{x-28}{8}$

Probability being less than 1 is here equal to the proportion also.

A) P(X>32) = P(Z>0.5)=0.5-0.1915=0.3085

B) P(X>40) = P(Z>1)=0.5-0.3413=0.1687

C) P(X<19) = P(Z<-1.125)=0.5-0.0438=0.4562

D) We have to find 19th percentile here

Z =-0.88

$X=28-0.88(8)\\=20.96$

Point A (-2-10) is reflected over the x axis write the coordinates of A

Arada [10]

The answer is (-2, 10) because when reflecting over the x, change the sign of y. When reflecting over the y, change the sign of x.
