First, you have to arrange them in proper numerical order (least to greatest).

84, 88,90,92,96

Next, find the mean by adding them all up and dividing them by 5.

84 + 88 + 90 + 92 + 96 = 450

450 divide by 5 equals 90.

Now, that we have our mean, we have to subtract it from each of the numbers in the data set. Remember this is absolute so there is no negatives.

84 - 90 = 6

88 - 90 = 2

90 - 90 = 0

92 - 90 =2

96 - 90 = 6

Next, line them up again.

2,2,6,6

Find the mean of them:

2 + 2 + 6 + 6 = 16

16 divided by 4 is 4.

Therefore, our answer would be the MAD is 4.0

Which products result in a perfect square trinomial? Select three options.

Kazeer [188]

Answer:

Second option: $(xy+x)(xy+x)$

Third option: $(2x-3)(-3+2x)$

Fifth option: $(4y^2+25)(25+4y^2)$

Step-by-step explanation:

By definition, a perfect square trinomial can be obtained by squaring binomials.

Then:

$(a+b)^2=(a+b)(a+b)=a^2+2ab+b^2\\\\(a-b)^2=(a-b)(a-b)=a^2-2ab+b^2$

Knowing this, to obtain a perfect square trinomial, the binomials that you multiply must be equals.

Therefore, the products result in a perfect square trinomial are:

$(xy+x)(xy+x)=(xy+x)^2=(xy)^2+2(xy)(x)+x^2=x^2y^2+2x^2y+x^2$

$(2x-3)(-3+2x)=(2x-3)^2=(2x)^2-2(2x)(3)+3^2=4x^2-12x+9$

$(4y^2+25)(25+4y^2)=(4y^2+25)^2=(4y^2)^2+2(4y^2)(25)+25^2=16y^4+200y^2+625$

The x3 was supposed to be an exponent not 3x

mote1985 [20]

Answer:

The value of x is $2\sqrt[3]{2}$

Step-by-step explanation:

We are given $2+x^3=18$

We need to solve for x

First we subtract 2 both sides

$x^3=18-2=16$

Taking cube roots both sides to isolate x

$x=\sqrt[3]{16}$

Simplify the radical

$x=2\sqrt[3]{2}$

Thus, The value of x is $2\sqrt[3]{2}$

A pair of sneakers are $ 164.99 . They are 25 % off. With this discount, what is the sale price?

Ivanshal [37]

Answer:

Discount: $41.25

Sale price: $123.74

Step-by-step explanation:

Discount=(Original price)x((discount %)/(100))

164.99x(25/100)

164x0.25

=$41.25

Sale price= (original price) - (discount)

164.99 - 41.25

= $123.74
