Exception if the integer is a negative

astra-53 [7]3 years ago

7 0

One <em><u>possible counterexample</u></em> is:

-1

Explanation:

The set of integers contains the set of whole numbers and negative numbers, but does not include fractions or decimals.

Multiplying positive 2 by any negative number will result in a negative product. Any negative number will be smaller than positive two; thus any negative number and 2 will have a product smaller than 2.

The purchasing director of a bank has just received a shipment of 100 printers. She has been told that the shipment includes 5 d

zaharov [31]

Since there is a 95% chance that you get two printers right, then you simply square the decimal equivalent which is .95 (Hence, you do .95^2). You will get .9025 (or 90.25%).

For letter b, you simply subtract .9025 from 1.
ans = 1-.9025
ans = .0975 (or 9.75%)

So the answer to B) would be there is a 9.75% chance the probability of a shipment can be rejected.

What is the area of the region bounded between the curves y=x and y=sqrt(x)?

erastova [34]

Answer:

$\frac{1}{6}$

Step-by-step explanation:

y = x .....(1)

$y=\sqrt{x}$ .... (2)

By solving equation (1) and equation (2)

$x = \sqrt{x}$

$\sqrt{x}\left ( \sqrt{x}-1 \right )=0$

$\sqrt{x}=0$ or $\left ( \sqrt{x}-1 \right )=0$

x = 0, x = 1

y = 0, y = 1

A = $\int_{0}^{1}ydx(curve)-\int_{0}^{1}ydx(line)$

A = $\int_{0}^{1}\sqrt{x}dx-\int_{0}^{1}xdx$

A = $\frac{2}{3}[x^\frac{3}{2}]_{0}^{1}-\frac{1}{2}[x^2]_{0}^{1}$

A = $\frac{2}{3}-\frac{1}{2}$

A = $\frac{1}{6}$

Jonah was standing at an elevation somewhere between-1 1/2

erma4kov [3.2K]

Answer:

$=-\frac{23}{12},\ -2$ and many others

Step-by-step explanation:

The limits given for Jonah's elevation with regards to sea level are

$-1\frac{1}{2}$ and $-2\frac{1}{3}$

Any number belonging to that interval could be the requested answer. We'll pick the exact center (mean value) between them:

$-1\frac{1}{2} =-\frac{3}{2}$

$-2\frac{1}{3}=-\frac{7}{3}$

Computing the mean value:

$\frac{1}{2}\left (-\frac{3}{2}-\frac{7}{3} \right)$

$=\frac{1}{2}\left (-\frac{23}{6}\right)$

$=-\frac{23}{12}$

Since $-2\frac{1}{3}=-2.33$

And $-1\frac{1}{2}=-1.5$

Other numbers like -1.6,-2,-2,3 can be examples of the required answer
