Step 1

<span>Find the two perfect square numbers it lies between.
</span>

<span>Solution:
</span>4²= 16 and 5² = 25, so lies between 4 and 5.

step 2

Divide 22 by 4. 22/4 = 5.5 (you can round off your answer)

step 3

Average 5.5 and 4. (5.5+4)/2 = 4.75

step 4

repeat step 2

Divide 22 by 4.75. 22/4.75 = 4.6316

step 5

repeat step 3

Average 4.75 and 4.6316. (4.75+4.6316)/2 = 4.6908

the answer is

4.69

what is the common number to be subtracted from each term of the ratio 11:8 to get the new ratio 2:1.?

JulijaS [17]

Answer:

5 should be subtracted from each term

Step-by-step explanation:

$\frac{11-x}{8-x}=\frac{2}{1}$

Cross multiply,

1 * (11 - x) = 2*(8-x)

11 -x = 2*8 - 2*x

11 - x = 16 - 2x

Subtract 11 from both sides,

-x = 16 - 2x - 11

-x = 5 - 2x

Add 2x to both sides

-x +2x = 5 - 2 + 2x

x = 5

Math 2 Homework Mod 2.1 (Day 2) Absolute Value Functions

Semenov [28]

The descriptions of the transformations are:

Vertex: (-6, 0)
Stretch factor: 2
Domain: set of all real numbers
Range: set of real numbers greater than or equal to 0

<h3>How to describe transformations, graph, and state domain & range using any notation?</h3>

The function is given as:

f(x) = -2|x + 6|

The above function is an absolute value function, and an absolute value function is represented as:

f(x) = a|x - h| + k

Where

Vertex = (h, k)

Scale factor = a

So, we have:

a = -2

(h, k) = (-6, 0)

There is no restriction to the input values.

So, the domain is the set of all real numbers

The y value in (h, k) = (-6, 0) is 0

i.e.

y = 0

Because the factor is negative (-2), then the vertex is a minimum

So, the range is all set of real numbers greater than or equal to 0

Hence, the descriptions of the transformations are:

Vertex: (-6, 0)
Stretch factor: 2
Domain: set of all real numbers
Range: set of real numbers greater than or equal to 0

Adult female height is normally distributed with a mean of 65.3 inches and a standard deviation of 2.32 inches. a) If an adult f

emmasim [6.3K]

Answer:

0.0423 is the probability that the adult female has a height less than 61.3 inches.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 65.3 inches

Standard Deviation, σ = 2.32 inches

We are given that the distribution of adult female height is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(adult female has a height less than 61.3 inches)

$P( x < 61.3) = P( z < \displaystyle\frac{61.3 - 65.3}{2.32}) = P(z < -1.7241)$

Calculation the value from standard normal z table, we have,

$P(x < 61.3) =0.0423 = 4.23\%$

0.0423 is the probability that the adult female has a height less than 61.3 inches.
