Since it has to do with probability I would say that the probability that she would pick a specific card would be 1:52 but for two would be 2:52 which would simplify to her chances being 1 out of 26 but I could be wrong.

Lisa has to cut her grandma's grass this weekend and wants to know exactly how much area she will be cutting. Calculate the area
Evgen [1.6K]

Answer:

  398 ft²

Step-by-step explanation:

Assuming you have correctly described the total area in terms of non-overlapping triangles and a rectangle, you can put the dimensions into the appropriate area formula and add up the pieces.

  Triangle area = 1/2·bh

  Rectangle area = bh

___

So, the <em>first triangle</em> has an area of ...

  1/2·(20 ft)(20 ft) = 200 ft²

The <em>second triangle</em> has an area of ...

  1/2·(6 ft)(6 ft) = 18 ft²

The <em>rectangle</em> has an area of ...

  (30 ft)(6 ft) = 180 ft²

And the area total is ...

  200 ft² +18 ft² +180 ft² = 398 ft²

Find the minimum, maximum, range, mean, and median for the data set.
Papessa [141]
Minimum: 37
maximum: 208
range: maximum - minimum = 208 - 37 = 171
mean: (37 + 43 + 54 + 83 + 102 + 117 + 160 + 208)/8 = 100.5
median: middle number (83 + 102)/2 = 92.5

The width of a human hair is 2 x 10-5 meters. The width of a piece of sand is 1.5 x 10¹ meters.
Elena L [17]

The difference in the widths, in meters, of the human hair and the piece of sand is 1.4998*10^{-1} m.

It is given in the question that:-

Width of a human hair = 2*10^{-5} m

Width of a piece of sand = 1.5*10^{-1}m

We have to find the difference in the widths, in meters, of the human hair and the piece of sand.

We know that,

Difference between the widths = Width of a piece of sand - Width of a human hair

Hence, we can write,

Difference between the widths =  2*10^{-5} m - 1.5*10^{-1}m

We can write,

1.5*10^{-1}=15000*10^{-5}

Hence,

Difference between the widths =

15000*10^{-5} - 2*10^{-5}= 14998*10^{-5} = 1.4998*10^{-1} m

Given ABCD is a parallelogram ABE equals 180° CBE is congruent to CEB prove DAE is congruent to CEA
katrin2010 [14]

Answer:

The proved is given below.

Step-by-step explanation:

Given ABCD is a parallelogram and also ∠ABE equals 180°, ∠CBE ≅ ∠CEB

We have to prove that ∠DAE ≅ ∠CEA

As ∠CEA=∠CBE  →  (1)

and given  ABCD is a parallelogram implies AD||CB

∴ ∠DAE=∠CBE  → (2)  as these are corresponding angles.

From equation (1) and (2), we get

∠DAE=∠CEA

Hence,  ∠DAE is congruent to ∠CEA

Hence Proved
