Reason:

2. SD ⊥ HT. ∴ ∠SDH = ∠SDT =90°

3. Given (It is given in the question)

5. RHS congruence

(Here, the right angle, hypotenuse and one side of ΔSHD is congruent to that of ΔSTD).

Statement:

4. Line segment SD = SD

(Reflexive property is used to prove congruence of triangles. This property is used when an angle or line segment is congruent to itself.)

Answer:

2. SD ⊥ HT. ∴ ∠SH = ∠ST =90° 3.

Step-by-step explanation:

Two right triangles are congruent if the hypotenuse and one side of one triangle are respectively equal to the hypotenuse and the corresponding side of the other triangle.

We know the side relations of a right angled Triangle (that is Pythagoras therom)

now, let the missing side be x

Hypotenuse² = sum of squares of other legs

that is ~

$15 {}^{2} = 5 {}^{2} + {x}^{2}$

$225 = 25 + {x}^{2}$

${x}^{2} = 225 - 25$

${x}^{2} = 200$

$x = \sqrt[]{200}$

$x = 10 \sqrt{2}$

The correct choice is ~ B

For a standard normal distribution (µ=0, σ=1), the area under the curve less than 1.25 is 0.894. What is the approximate percent

Nesterboy [21]

Answer:

10.6%

Step-by-step explanation:

Normal curves are symmetrical. That means that on a standard normal distribution, the area less than -1.25 is the same as the area greater than +1.25. The total area under the curve is 1, so:

P = 1 - 0.894

P = 0.106

Approximately 10.6% of the area under the curve lies below -1.25.
