Answer: 9b - 8b

Step-by-step explanation:

ou need two factors that you will multiply together to give you -72b^2 and at the same time when you add this two factors it will give you + b . Check; 9b X -8b = -72b^2 and 9b + (-8b) = b , that is why 9b and -8b are the factors and they will replace the middle value

NemiM [27]
Okay. So, Kedar earns a monthly salary of $2,200 per month. That stays the same. He earns a 3.75% monthly commission on how much he sells. To find out how much his commission would be if he sold $4,500 in clothing, we would have to multiply 4,500 by 3.75% (0.0375). When you multiply both numbers, you get $168.75 in commission sales. Now, you must add that plus 2,200. When you add both of those numbers, you get 2,368.75. Kedar would earn $2,368.75 this month if he sold $4,500 worth of clothes.

Using Normal Distribution, what is the area to the right of 0.72 under the
natima [27]

Answer: 0.2358

Step-by-step explanation:

Using Normal Distribution, under the  standard normal curve

The area to the right of z is given by P(Z>z)=1-P(Z<z)

So, the area to the right of z= 0.72 under the  standard normal curve would be:

P(Z>0.72)=1-P(z<0.72)

=1-0.7642   [By using p-value table]

= 0.2358

Hence, the area to the right of z= 0.72 under the  standard normal curve is 0.2358 .
