A triangle is placed in a semicircle with a radius of 9 cm
julsineya [31]
Considering that the shaded area is the part of the semi circle outside the triangle:
Area of circle= Pi x radius2 (this means radius squared)
Area of triangle= 1/2 x base x height
1/2 (because it is a semi circle) x 3.14 (in replacement of pi as directed by question) x 9squared= 127.17

127.17 - (1/2 x 18 x 9) = 46.17cmsquared

The number of girl child per family was recorded for 1000 families with 3 children. The data obtained was as follows: [2] Number
ira [324]

Answer:

a.\ Probability = 0.426

b.\ Probability = 0.574

Step-by-step explanation:

Given

Total\ Families = 1000

Number of Girls :      0 ---->  1 -----> 2   ------->3

Number of Families: 112 -> 314 --> 382 ---> 192

Solving (a): At most one girl

From the table, the number of families with at most one girl is: 112 + 314

i.e.

Number of Girls :      0 ---->  1

Number of Families: 112 -> 314

So, we have:

At\ Most\ One\ Girl = 112 + 314

At\ Most\ One\ Girl = 426

The probability is then calculated as:

Probability = \frac{At\ Most\ One\ Girl}{Total}

Probability = \frac{426}{1000}

Probability = 0.426

Solving (b): More girls

From the table, the number of families with more girl is: 382 + 192

i.e.

Number of Girls :      -----> 2   ------->3

Number of Families: --> 382 ---> 192

So, we have:

More\ Girls = 382 + 192

More\ Girls = 574

The probability is then calculated as:

Probability = \frac{More\ Girls}{Total}

Probability = \frac{574}{1000}

Probability = 0.574

Which expression is equivalent to StartFraction b Superscript negative 2 Baseline Over a b Superscript negative 3 Baseline EndFr
nignag [31]

Answer:

  • \frac{b^{-2}}{ab^{-3}}=\frac{b}{a}

Step-by-step explanation:

Writing the description in algebraic translation

\frac{b^{-2}}{ab^{-3}}

so we have to find the expression which will be equal to \frac{b^{-2}}{ab^{-3}}.

Considering the expression

\frac{b^{-2}}{ab^{-3}}

\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}

\frac{b^{-2}}{b^{-3}}=b^{-2-\left(-3\right)}

so the expression becomes

=\frac{b^{-2-\left(-3\right)}}{a}            ∵ \frac{b^{-2}}{b^{-3}}=b^{-2-\left(-3\right)}

\mathrm{Subtract\:the\:numbers:}\:-2-\left(-3\right)=1

=\frac{b}{a}

Therefore,

                    \frac{b^{-2}}{ab^{-3}}=\frac{b}{a}
