construct a right-angled triangle ABC where angle A =90 degree , BC= 4.5cm and AC= 7cm. please ans fast........ Very urgent. Pls

Katena32 [7]

Answer and Step-by-step explanation: The described right triangle is in the attachment.

As it is shown, AC is the hypotenuse and BC and AB are the sides, so use Pytagorean Theorem to find the unknown measure:

AC² = AB² + BC²

$AB^{2} = AC^{2}-BC^{2}$

$AB =\sqrt{AC^{2}-BC^{2}}$

$AB =\sqrt{7^{2}-4.5^{2}}$

$AB =\sqrt{28.75}$

AB = 5.4

Then, right triangle ABC measures:

AB = 5.4cm

BC = 4.5cm

AC = 7cm

If you have a chance to win $500 for drawing a card of 10 of any suit from a standard deck of cards, what is the value of expect

Dimas [21]

The expected value is $38.46.

The probability of drawing a 10 from any suit is 4/52. Multiply this by the earnings, 500:

4/52(500) = 2000/52 = 38.46

Question 2.what is the probability that between 80 and 115 complaints are received in one week? use a n(110,20) model to approxi

AURORKA [14]

Calculate standard Z values for the given data:-

z = (80 - 110) / 20 = - 3/2 = -1.5

and z = (115 - 110) / 20 = 0.25

so we need Prob ( -1.5 < z < 0.25)

Using standard tables this comes to 0.5319 Answer
