Answer:

Standard deviation =2.6

Step-by-step explanation:

Using the formula given

S = √((1/n-1)∑(x-x⁻)²)

n = 5

∑(x-x⁻)² = 34

Therefore;

s = √(1/5(34)

= √6.8

 = 2.6 

The standard deviation will be 2.6

Quadrilateral abcd is a rhombus and points c, d, and e are on the same line. is quadrilateral abde a rhombus?

Step2247 [10]

No, because BC and BD are not the same lengths. If AB = BC, then AB and BD are not the same lengths -> ABDE is not a rhombus.

a 12-ft ladder leans against a building so that the angle between the ground and the ladder is 74°. how high does the ladder rea

WINSTONCH [101]

Answer:

12 feet

Step-by-step explanation:

Sometimes, a simple drawing is a great way to start! In the attached drawing, the red line represents the ladder, the brown represents the ground, and the black represents the building!

We want to find the side of the triangle from where the ladder meets the building to where the building meets the ground. This can be found using trigonometric identities, namely sine:

$sin\theta=\frac{opposite}{hypotenuse}$

Plug in known values:

$sin(74^o)=\frac{x}{12}$

Rearrange to isolate the variable:

$x=12sin(74^o)$

Simplify!

$x=11.535140... ft$

Round to the nearest foot:

$x=12ft$

Can any help me please

A = 8i + 6j
b = 4i + 5j

ab = (8i + 6j)(4i + 5j)
ab = 8i(4i + 5j) + 6j(4i + 5j)
ab = 8i(4i) + 8i(5j) + 6j(4i) + 6j(5j)
ab = 32i² + 40ij + 24ij + 30j²
ab = 32i² + 64ij + 30j²
ab = <32, 30>

The answer is D.

When there are 20 sheep, each sheep has 100 square yards of grazing area . How many yards are available for each sheep when ther

ZanzabumX [31]

Answer:

80 square yards

Step-by-step explanation:

so you have to divide 20 into 100 to see how much each sheep gets. Each sheep gets 5 square yards. Then you just multiply how much each sheep gets by 5 and get 80 square yards.
