Answer:

  1. 10
  2. 15ab

Step-by-step explanation:

1. The square of the binomial is ...

  (* -2m)^2 = *^2 -4m* +4m^2

Matching terms, you find ...

  *^2 = 100

  -4m* = -40

Both of these equations tell you the value of * is 10.

___

2. Same deal. Multiply ou the square and see what you have.

  (3a +2.5b)^2 = 9a^2 +15ab +6.25b^2

The term missing on the right side of the given equation is 15ab.

Airida [17]

Answer:

When the tail is pulled toward the right side, it is called a positively skewed distribution

Step-by-step explanation:

When the tail is pulled toward the right side, it is called a positively skewed distribution; when the tail is pulled toward the left side of the curve it is called a negatively skewed distribution (Watzlaf 2016, 361-362).

Generally the right side of a function is reserved for positive variables and the left side is used to represent negative variables, therefore when a function is pulled to the right is considered to be Positively skewed

yan [13]
If you would like to know how many minutes were spent on language arts, you can calculate this using the following steps:

60% of 40 minutes = 60% * 40 = 60/100 * 40 = 24 minutes

The correct result would be: 24 minutes were spent on language arts.

Help Pls! It's for my Math 4! Scalar Multiplication!
prohojiy [21]

Answer:

Concept: Physics Qualitative Analysis.

  • Scalar values are constant and compared to vector values they do not have a direction or magnitude or a gradient representation.
  1. Lets get started by setting up the equation
  2. They want us to find 3U-2V
  3. Given U= <6,6> V=<6,-6>
  4. Now we plug in and solve!
  5. 3<6,6>- 2<6,-6>
  6. <18,18>-<12,-12>
  7. Subtract
  8. <18-12,18-(-12)>
  9. Hence that gives us a result of <6,30>
  10. Now with the skills you gained solve the rest!!!
