The probability of obtaining nine heads in a row when flipping a coin is

1 answer:

Gelneren [198K]3 years ago

7 0

Answer: The probability is about 0.2%.

The probability of flipping heads one time is 0.5, 50% or 1/2.

To flip heads 9 times in a row, we have to multiply 1/2 by itself 9 times.

(1/2)^9 = 1/512 or about 0.2%

It should only happen once every 512 times.

Is 4/7 24/35 perform<br> a ratio

uysha [10]

No. If 4x= 24 then x=6. 7 multiplied by 6 equals 42, not 35 so this is not a ratio.

YS is the perpendicular bisector of XYZ and YS is a shared side of XYS and ZYS. which of the following must be congrent in order

german

Answer:

The triangles SYX and SYZ are congrient so by CPCTC $XY\cong YZ$ , $XS\cong ZS$ and $\angle X\cong \angle Z$ .

Step-by-step explanation:

Given information: YS is the perpendicular bisector of XYZ.

In triangle YXS and triangle YSZ,

$\angle SYX=\angle SYZ$ (YS is the perpendicular bisector of XYZ)

$YS=YS$ (Common side, Reflexive property)

$\angle YSX=\angle YSZ=90^{\circ}$ (YS is the perpendicular bisector of XYZ)

By ASA postulate,

$\triangle SYX\cong \angle SYZ$

The corresponding parts of congruent triangles are congruent. so,

$XY\cong YZ$

$XS\cong ZS$

$\angle X\cong \angle Z$
