Not a 5 dollar just means a 10 dollar

probblity=desired outcomes/total possible outcomes

desired=number of 10 dollar notes or 30

total possible=10+30 or 40

the probablity is 30/40 or 3/4 or 75% that you do not select a 5 dollar note

The formula for the area of a parallelogram is A = bh, where b is the base and h is the height. A parallelogram that is not draw

Bezzdna [24]

Answer:

Option 2) 2x3 – 6x2 – 14x + 24 square centimeters

Step-by-step explanation:

We know the Parallelogram Area is given by

$A=bh$ Eqn. (1)

where

$b$ : is the base

$h$ : is the height

We are also given that the base is

$b=2x^2+2x-6$

and the height is

$h=x-4$

So we can plug these two expressions in Eqn. (1), simplify and find our Area equation as follow:

$A=(2x^2+2x-6)(x-4)\\\\A=(2x^2)(x)+(2x)(x)-(6)(x)+(2x^2)(-4)+(2x)(-4)-(6)(-4)\\\\A=2x^3+2x^2-6x-8x^2-8x+24\\\\A=2x^3+2x^2-8x^2-6x-8x+24\\\\A=2x^3-6x^2-14x+24$

Which matches Option 2. from the available ones.

Covert 12/20 to a decimal

oksano4ka [1.4K]

Answer:

.60

Step-by-step explanation:

The way you do this is by getting the denominator to 100

Take 20 and multiply it by 5 and then take 12 and do the same.

That gives you 60/100 which is the same as .60

Hope this helped ! !

Pls, can you help me? thx.<br><img src="https://tex.z-dn.net/?f=%20%5Ccos%28x%20%2B%20%5Cfrac%7B%5Cpi%7D%7B3%7D%29%20%5Cgeqslant

Veseljchak [2.6K]

For $x$ between $-\pi$ and $\pi$ , we have

$\cos x=\frac{\sqrt2}2=\frac1{\sqrt2}$ when $x=\pm\frac\pi4$ ;
$\cos x=1$ for $x=0$ ; and
$\cos x=0$ for $x=\pm\frac\pi2$

$\cos x$ is continuous over its domain, so the intermediate value theorem tells us that

$\cos x\ge\frac{\sqrt2}2$

is true for $-\frac\pi4\le x\le\frac\pi4$ .

For all $x$ , we take into account that $\cos x$ is $2\pi$ -periodic, so the above inequality can be expanded to

$-\dfrac\pi4\le x+2n\pi\le\dfrac\pi4$

where $n$ is any integer. Equivalently,

$-\dfrac\pi4-2n\pi\le x\le\dfrac\pi4-2n\pi$

To get the corresponding solution set for

$\cos\left(x+\dfrac\pi3\right)\ge\dfrac{\sqrt2}2$

simply replace $x$ with $x+\frac\pi3$ :

$-\dfrac\pi4-2n\pi\le x+\dfrac\pi3\le\dfrac\pi4-2n\pi$

$\implies\boxed{-\dfrac{7\pi}{12}-2n\pi\le x\le-\dfrac\pi{12}-2n\pi}$

Please help! Correct answers only please! The M&M jar has a square base with a length and width of 7 cm and a height of 6.5

Tcecarenko [31]

Answer: a) 100

<u>Step-by-step explanation:</u>

Volume (V) of the prism = Length(L) x width(w) x height(h)

V = 7 x 7 x 6.5

= 318.5 cm³

Next, what is the volume of an M & M? The info isn't given so according to the internet it is 0.636 cm³

$\text{Quantity}=\dfrac{\text{Volume of the prism}}{\text{Volume of an M}\ \&\ \text{M}}}=\dfrac{318.5}{0.636}=\large\boxed{500}$

The nearest answer to this is: (a) 100

because the upper limit cannot be 10,000
