4 0

Answer:

Step-by-step explanation:

This is a normal distribution with the mean of 14 g/dL and a standard deviation of 1 g/dL.

For less than 13 ( 13 = mean - 1 standard deviation and less ):

16 % of 200, 0.16 * 200 = 32 people.

For greater than 14 ( mean and greater ):  50 % of 200 = 100 people.

A bag contains three red marbles, two green ones, one lavender one, four yellows, and five orange marbles. HINT [See Example 7.
lilavasa [31]
<h2>Answer:</h2>

<em><u>Number of possible sets = 4</u></em>

<h2>Step-by-step explanation:</h2>

In the question,

Number of Red marbles in the bag = 3

Number of Green marbles in the bag = 2

Number of Lavender marbles in the bag = 1

Number of Yellow marbles in the bag = 4

Number of Orange marbles in the bag = 5

So,

If we need to form a set having all the red marbles then,

We have 3 Red marbles and only the set of 4 is needed to be made.

For that,

We have <u>4 different options,</u>

1 Green + 3 Red

1 Lavender + 3 Red

1 Yellow + 3 Red

and,

1 Orange + 3 Red.

<em><u>Therefore, there are only 4 such cases which include all the Red marbles in them.</u></em>

<em><u></u></em>

Solve the formula for x.<br> S=2πzx+7πz2
Lubov Fominskaja [6]

Answer:

<u>Given:</u>

  • S = 2πzx + 7πz²

<u>Isolate x:</u>

  • 2πzx = S - 7πz²

<u>Divide both sides by 2πz:</u>

  • x = (S - 7πz²)/(2πz)
  • x = S/(2πz) - 3.5z

Quadrilateral FRIO is the result of a reflection of quadrilateral LAMB over the y-axis. FRIO has vertices at F(-7,6), R(1,7), I(
andrew11 [14]

Answer:

F' = (7, 6)

R' = (-1, 7)

I' = (-2, -5)

O' = (6, -6)

Step-by-step explanation:

The rule of reflection over the y-axis is, (x, y) ---> (-x, y). So change all the x values into the opposite signs. So the -7 of F would turn into just 7, the 1 of R would turn into -1, the 2 of I would turn into -2, and -6 of O would turn into just 6.
