Angelina_Jolie [31]

Answer:

$P(z>1.51) =1-P(Z$

And i fwe look into the normalstandar dtable we can find the desired probability:

$P(z>1.51) =1-P(Z$

And then the The area to the right of z = 1.51 is 0.0655

Step-by-step explanation:

For this case we want to find the following probability:

$P(z>1.51)$

And for this case we can use the normal standard distribution and the complement rule and we have this:

$P(z>1.51) =1-P(Z$

And i fwe look into the normalstandar dtable we can find the desired probability:

$P(z>1.51) =1-P(Z$

And then the The area to the right of z = 1.51 is 0.0655

3.Find the area of Triangle and Parallelogram having base 13.5cm and height is 18cm.

patriot [66]

Base=13.5cm
Height=18cm

$\\ \sf\longmapsto Area=\dfrac{1}{2}Base\times Height$

$\\ \sf\longmapsto Area=\dfrac{1}{2}(18)(13.5)$

$\\ \sf\longmapsto Area=9(13.5)$

$\\ \sf\longmapsto Area=121.5cm^2$
