Find The Exact Value Of X.x=

Answers

Answer 1

Answer:

6.73

Step-by-step explanation:

Remark

There might be an easier way to do this problem. I'm certain I don't know what it is. Begin by called WY = y

Givens

WY = y

WZ = x

XW = 25 - y

XZ = 24

YZ = 7

Equations

x^2 + y^2 = 7^2

(25 - y)^2 + x^2 = 24^2

Solution

x^2 = 7^2 - y^2

x^2 = 24^2 - (25 - y)^2

Since both xs are the same, you can equate the right side of the equations.

7^2 - y^2 = 24^2 - (25 - y)^2                 Expand the brackets

7^2 - y^2 = 24^2 - (625 - 50y + y^2)    Remove the brackets.

7^2 - y^2 = 576 - 625 + 50y - y^2        Cancel the y^2. Combine 576 and 625

49  = - 49 + 50y                                    Add 49 to both sides

98 = 50y                                               Divide by 50

y = 1.96

Now use y to find x

x^2 + y^2 = 7^2

x^2 = 7^2 - 1.96^2

x^2 = 45.1584

x = 6.72

Answer 2

9514 1404 393

Answer:

  x = 6.72

Step-by-step explanation:

The triangles are all similar, so the ratios of corresponding sides are the same.

  short leg/hypotenuse = 7/25 = x/24

  x = 24(7/25)

  x = 6.72

The expected value of a random variable with the following probability distribution will be 7.

How to calculate the expectation of a discrete random variable?

Expectation can be taken as a weighted mean, weights being the probability of occurrence of that specific observation.

Thus, if the random variable is X, and its probability mass function is given being  f(x) = P(X = x), then we have:

[tex]E(X) = \sum_{i=1}^n( f(x_i) \times x_i)[/tex]

[tex]\rm E(X)=2 \times \frac{1}{36} +3 \times \frac{1}{28} +4 \times \frac{1}{12} +5 \times \frac{1}{9} +6 \times \frac{5}{36} + 7 \times \frac{1}{6} +8 \times \frac{5}{36}+9 \times \frac{1}{9} +10 \times \frac{1}{12} +11 \times \frac{1}{18} +12 \times \frac{1}{36} \\\\ E(X)=7[/tex]

Hence the expected value of a random variable will be 7.

Answers

Answer:

£5

Step-by-step explanation:

5 boxes will cose 5 x 15.40 = 77 normally.

according to the table, he will get 6.5% discount.

6.5 percent of 77 is 77x0.065 = 5.005 ≈ 5

Answer:

he orders 5 boxes of paperclips, that comes around to 77 dollars. That means he will get a 6.5 percent discount. So you would multiply 77 by .065 and you would get 5.005. You would take that number and subtract it by 77 and would get 71.995 and you can round that up to 72 dollars. My guess is that either 72 or 5.005 is the answer as 72 dollars is the price after the discount and 5.005 is how much he is saving

(b) A farmer uses of his land to plant
cassava, of the remaining land to plant
maize and the rest vegetables. If
vegetables cover an area of 10 arces, what
is the total area of the farmer's land.​

Answers

Answer:

Cassava = ⅓ or 33.333%

Maize = ⅔x⅔ = 44.444%

total so far =77.777%

Remaining vegetable area =(100–77.777%) = 22.222%

If remaining area vegetables = 22.222% = 10 acres

Maize = ⅔x⅔ = 44.444% or 20 acres

Cassava = ⅓ or 33.333% or 15 acres

Total land area = 45 acres.
