Answer:
8-6i
Step-by-step explanation:
complex number in standard form will be in the form of a+bi
(-2 − 2i) + (10 − 4i) , open parenthesis
-2- 2i +10 -4i, group like terms
-2+10 -2i -4i, combine like terms
8 - 6i
<span>-1/4y(2y^3 - 8)
= -1/2 y^4 + 2 y</span>
Answer: 1 dozen cupcakes can be made in 12 cups of flour.
Step-by-step explanation:
Given : The amount of flour a baker has = 

The number of cupcakes he made by using all flour = 
i.e.
cupcakes made in
cups of flour
By unitary method ,
1 cupcake made in
cups of flour.
i.e. 1 cupcake made in
cups of flour.
Then , 12 cupcakes can be made in
cups of flour.
= 27 cups of flour.
Since<em> 1 dozen = 12</em>
Then , 1 dozen cupcakes can be made in 12 cups of flour.
A median is 65 inches and a standard deviation is 1.7:
a. 65 + 1 SD = 65 + 1.7 = 66.7 in
It means that there are : 100% - ( 50% + 34% ) = 100% - 84% = 16% students taller than 66.7 inches.
b. Heights between 61.6 in and 68.7 in are within 2 standard deviations:
13.5% + 34% + 13.5% + 34% = 95%
0.95 * 300 = 285
There are 285 students between 61.6 in and 68.7 in tall.
