a) value of x:

ZX =(10x+9)°

122°=( 10x+9)

122 - 9= 10x

113= 10x

x = 113/10= 11.3 °

so answer is = 11.3°

b) measure of Arc XZ :

formula to find Arc= © angle÷360 x 2πr

A = 122÷360 x 2πr

A = 61/180x 2πr

A = 0.3388x2πr

A= 0.6776πr

The amount of time it takes Isabella to wait for the bus is continuous and uniformly distributed between 3 minutes and 17 minute

Arturiano [62]

Answer:

P(X>5) = 0.857

Step-by-step explanation:

Let X $\sim$ uniform(3.17)

$f(x) = \dfrac{1}{17-3} ; \ \ \ 3 \le x \le 17$

The required probability that it will take Isabella more than 5 minutes to wait for the bus can be computed as:

$P(X > 5) = \int ^{17}_{5} f(x) \ dx$

$P(X > 5) = \int ^{17}_{5} \dfrac{1}{17-3} \ dx$

$P(X > 5) =\dfrac{1}{14} \Big [x \Big ] ^{17}_{5}$

$P(X > 5) =\dfrac{1}{14} [17-5]$

$P(X > 5) =\dfrac{12}{14}$

P(X>5) = 0.857

Nadya filled a right rectangular prism with cubes that are 1/2 inch long each edge. She stacked 80 cubes in the prism and filled

vovangra [49]

Answer

<h2>The volume of right rectangular prism 10 cubic inch.</h2>

Step-by-step explanation:

The volume of cube $=a^{3}$

each edge of cube $=\frac{1}{2}$ inch

so,

the volume of cube $=\left [ \frac{1}{2} \right ]^{^{3}}$

one cube of volume $=\frac{1}{8}$ cubic inch.

$80$ cube of volume $=80\times\frac{1}{8}=10$ cubic inch

so the volume of rectangular prisme equal to volume of 80 cube.
