An honest coin is flipped 4 times. Given that the coin landed heads up more than two, what is the probability that it landed hea
arsen [322]

Answer:

probability of getting four head consecutively is 0.2

Step-by-step explanation:

in an experiment coin is flipped 4 times.

given,  coin landed heads up more than two times

outcomes of  coin landed heads up more than two times =

 SAMPLE SPACE :    [ {HHHT}{HHTH}{HTHH}{THHH}{HHHH} ]

chance of getting 4 heads = 1 (HHHH)

Probability = \dfrac{1}{5}

hence the probability of getting four head consecutively is 0.2

∠3 and ∠6 are alternate interior angles. If m∠3 = 75, what is the measure of ∠6
sp2606 [1]

Answer:

<h3>B. m<3 = m<6 = 75degrees</h3>

Step-by-step explanation:

First you must understand that in geometry, the alternate interior angles are equal

Hence if ∠3 and ∠6 are alternate interior angles, then <3 = <6

Given that m<3 = 75 degrees

m<6 will also be 75 degrees since both angles are equal

A garden is designed in the shape of a rhombus formed from 4 identical 30°-60°-90° triangles. The shorter distance across the mi
g100num [7]
legs of the triangles

Each triangle 30-60-90 is:

         one leg: 15 ft => short diagonal = 2 * 15ft = 30ft

         other leg, x:

         tan(30) = 15 / x => x = 15 ft / tan(30) = 25.98 ft

=> long diagonal = 2 * 25.98ft = 51.96 ft

side of the rhoumbus =  hypotenuse of one triangle

side of the rhombus = √ [ (15)^2 + (25.98)^2 ] = √(900) = 30 ft

Area of the rhombus:

4 * area of one triangle = 4 [base*height/2] = 4*15*25.98/2 = 779.43 ft^2

The shortest distance accross the garden is equal to the side of the rhombus = 30 ft
