Answer:

This hypothesis is a Directional Hypothesis.

Step-by-step explanation:

Family centered care is a significant predictor of children's health-related quality of life, independent of illness severity.

This hypothesis is a Directional Hypothesis.

Directional hypothesis predicts the way in which the independent variable will affect the dependent variable.

Here, independent variable is - family centered care

Dependent variable is - health related quality of life

We can see that when family centered care is of great quality, there is no severe illness for children.

A used car was purchased in July 1999 for $11,900. If the car depreciates 13% of it's value each year, what is the value of the
trapecia [35]
1999 price = 11900
it depreciates 13%
\frac{13}{100} \times 11900 = 1547
year 2000 cost = 11900 - 1547 = 10353
it depreciates 13%
\frac{13}{100} \times 10353 = 1345.89
year 2001 cost = 10353 - 1345.89 = 9007.11
it depreciates 13%
\frac{13}{100} \times 9007.11 = 1170.92
year 2002 cost = 9007.11 - 1170.92 = 7836.19

you are installing a support wire for an electrical pole. the pole is 25 feet and the ground connection is 10 feet from the base
aniked [119]

ans=26.92

use trigonometric ratios

a²= b²+c²

a²=25²+10²

a²=625+100

now take square root on both sides

a

\sqrt{a { }^{2} }  =  \sqrt{725}

a=26.92

a=27 (2decimal place)

The depth of a local river averages 20 ft, which is represented as |−20|. In January, it measured 6 ft deep, or |−6|, and in Jul
mr_godi [17]

The computation shows that the difference in depth is 16 feet

<h3>How to calculate the value?</h3>

From the information, in January, it measured 6 ft deep, or |−6|, and in July, it was -22.

Therefore the difference between the depth will be:

= -6 - (-22)

= -6 + 22

= 16

Therefore, the difference in depth is 16 feet

Answer:

a. 10x + 4; the answer is a polynomial

Step-by-step explanation:

The perimeter of a rectangle is the sum of the lengths of the 4 sides.

The closure property is that if you add polynomials, the sum is a polynomial.

A rectangle has two congruent lengths and two congruent widths.

Since the length of the rectangle is 3x + 5, there is another length of 3x + 5. The width is 2x - 3, so there is a second width of also 2x - 3.

Let's add the 4 sides together:

3x + 5 + 3x + 5 + 2x - 3 + 2x - 3 =

= 3x + 3x + 2x + 2x + 5 + 5 - 3 - 3

= 10x + 4

The perimeter is 10x + 4. Each side length is a polynomial, and the sum of the all the side length is also a polynomial. This shows there is closure for the addition of polynomials.

Answer: a. 10x + 4; the answer is a polynomial
