Reil [10]3 years ago
3 0

Answer: 238.8

Step-by-step explanation:

To get an average, you add the weights together, the sum. And then you divide by how many children there was.

To go backwards, you'd times the average by the amount of children there were, 3, to get the sum

79.6 times 3 is 238.8

If f(x) = 3x + 2 and
WARRIOR [948]

Answer:

<h2>A. x + 4</h2>

Step-by-step explanation:

(f - g)(x) = f(x) - g(x)

f(x) = 3x + 2, g(x) = 2x - 2.

Substitute:

(f - g)(x) = (3x + 2) - (2x - 2) = 3x + 2 - 2x - (-2) = 3x + 2 - 2x + 2

<em>combine like terms</em>

(f - g)(x) = (3x - 2x) + (2 + 2) = x + 4

When randomly selecting an​ adult, A denotes the event of selecting someone with blue eyes. What do Upper P (Upper A )P(A) and U
bezimeni [28]

Answer:

P(A): It is the probability of selecting someone with blue eyes.  

P(\bar{A}): It is the probability of selecting someone who does not have blue eyes

Step-by-step explanation:

We are given the following in the question:

A: event of selecting someone with blue eyes.

Probability:

  • The probability of an event tells the chances of happening of that event.
  • It is mathematically defined as:

\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}

Complement of an event:

  • It is the event that consist of all outcomes not happening in A.
  • It is represented by \bar{A}
  • P(A) + P(\bar{A}) = 1

We have to explain the representation:

a) P(A): It is the probability of selecting someone with blue eyes.

It gives us the chances of someone having blue eyes.

b) P(\bar{A}): It is the probability of selecting someone who does not have blue eyes

It is the chances of selecting someone who does not have blue eyes.

Using the figure, find x and y
kakasveta [241]

Answer:

  • x = 8
  • y = 2√3

Step-by-step explanation:

The triangle is recognizable as a 30°-60°-90° right triangle, which has side length ratios ...

  1 : √3 : 2

Side x is thus twice the length of short side 4, so x = 8.

Side y is √3 times the length of short side x-6 = 2, so y = 2√3.

_____

If you don't happen to recognize the triangle dimensions, you can find x and y using the Pythagorean theorem.

  x = √(4² +(4√3)²) = √64 = 8

  y = √(4² -2²) = √12 = 2√3
