Answer:

0.21

Step-by-step explanation:

Given a distribution :

N(0, 1) - - - > Normal distribution

Probability of obtaining a non - negative observation :

P(x ≥ 0) = 0.5 ( Z probability calculator)

Hence, p = 0.5 ; (1 - p) = 1 - 0.5 = 0.5

P(x = 4) :

Using the binomial probability function :

P(x = x) = nCx * p^x * (1 - p)^(n-x)

P(x = 4) = 10C4 * 0.5^4 * 0.5^10 - 4

P(x = 4) = 210 * 0.0625 * 0.015625

P(x = 4) = 0.205078125

P(x = 4) = 0.21

Answer:

Blue: 13/100 = 0.13 = 13%

Purple: 130/100=1.3=130%

Step-by-step explanation:

The picture shows 100 cubes in a grid that's 10 by 10. This means the shaded amount is a number out of 100. The first is 13 out of 100 which converts to 0.13 and 13%. The second has all the cubes shaded which means 100/100 which is 1 or 100% plus the last has 30 cubes out of 100 which converts to 0.30 or 30%. Together this makes 130/100 or 1.30 or 130%.

Which one do i choose fam? I suck at geometry
Viefleur [7K]
The best choice would probably be the third option from the top. Since by using the distance formula you can solve for the length or distance of each of the sides of the triangle, and check to see if it is equal. As would be in an equilateral triangle.

Slope wouldn’t be best for the last leg or bottom leg as there is no change in y and x.

elixir [45]

Answer:

  C. 3

Step-by-step explanation:

You know the angle sum is ...

  ∠FGT +∠TGH = ∠FGH

You can use this relation with the given values to find x.

 90 + (8x +4) = 39x +1

  93 = 31x . . . . . . . . . . . . . add -1-8x, collect terms

  3 = x . . . . . . . . . . . . . . . . divide by 31

If ABC and EDC are similar, what is the value<br> of x?<br> A
abruzzese [7]

Answer:

x = 15

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

BC/DC = EC/AC , substitute values

3x×5/32 - 5x-5/56 ( cross- multiply )

56(3x - 5) = 32(5x - 5) ← distribute and simplify both sides

168x - 280 = 160x - 160 ( subtract 160x from both sides )

8x - 280 = - 160 ( add 280 to both sides )

8x = 120 ( divide both sides by 8 )

x = 15
