The answer is 2. If you were to make a box plot you’d subtract the second highest dot from the second lowest dot. That’s be your IQR.

The net of a square pyramid is shown

Wewaii [24]

Answer:

Option (D)

Step-by-step explanation:

Surface area of a square pyramid is determined from the formula,

Surface area = Area of the square base + 4(Area of one lateral triangular side)

Area of the base = (Side)²

= 8²

= 64 cm²

Area of one lateral triangle = $\frac{1}{2}(\text{Base})(\text{Height})$

= $\frac{1}{2}(8)(8)$

= 32 cm²

Therefore, surface area of the square pyramid = 64 + 4(32)

= 64 + 128

= 192 cm²

Therefore, Option (D) will be the correct option.

Use quadratic formula to find both solutions to the quadratic equation given below . 3x^2-5x-1=0

Rudiy27

Answer:

$x1=\frac{5+\sqrt{37}} {6}$

$x2=\frac{5-\sqrt{37}} {6}$

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$3x^{2} -5x-1=0$

$a=3\\b=-5\\c=-1$

substitute in the formula

$x=\frac{5(+/-)\sqrt{(-5)^{2}-4(3)(-1)}} {2(3)}$

$x=\frac{5(+/-)\sqrt{37}} {6}$

$x1=\frac{5+\sqrt{37}} {6}$

$x2=\frac{5-\sqrt{37}} {6}$
