the correct question in the attached figure
<span>
we know that

</span>the probability
that a witness picks a particular person by chance-----> P=1/5

the probability
that all 7 witnesses would pick the same person-----> P=1/5^7=0.0000128

the answer is the option B 0.0000128

<span>There are a variety of problems in which the number of witnesses change, for example
</span><span>....find the probability that all 9 witnesses would pick the same person

</span>in this case, the probability would be-------> P=1/5^9=0.000000512<span>

A patio has an area of 1420 square feet. If the length is 45 1/2, what is the width​
Anni [7]

[ Answer ]

\boxed{Width \ = \ 31\frac{19}{91} \ Ft^{2}}

[ Explanation ]

Area = 1420

Width = 45\frac{1}{2}

Area For Rectangle: Length · Width

Use division to find width:

1420 ÷ 45\frac{1}{2}

Convert mixed numbers to fractions:

1420 = \frac{1420}{1}

45\frac{1}{2} = \frac{91}{2}

\frac{1420}{1} ÷ \frac{91}{2}

Use mixed multiplication:

\frac{1420*2}{1*91}

= \frac{2140}{91}

Simplify:

= 31\frac{19}{91}

\boxed{[ \ Eclipsed \ ]}

Bas_tet [7]
All numbers that are 0._ are _/10 therefore that would be 9/10 because this ratio cannot be simplified further.

Can anyone show me how I would figure this problem out
jeka57 [31]

The value of x is the number inside the parenthesis, so h(-4) gives x a value of -4.

The equation says when X is ≤ -4 use the first equation


So h(-4) = -1/2(x) -15

= -1/2(-4) -15

= 2 -15

= -13


When x = -2 (h(-2) ) use the 2nd equation:

h(-2) = 20-3x^2

=20-3(-2)^2

= 20-3(4)

=20-12

=8


Now you have -13 + 3(8)

= -13 + 24

=11


The answer should be 11
