Factorising an equation is putting it into bracket form.
This has square numbers and so needs double brackets

(5x - y) (5x+y)
If you then check this by multiplying the brackets out again you will get:
 5x^2 - 5xy + 5xy - y^2

The positive and negative 5xy's cancel each other out and you are left with its original form. Your answer is
(<span>5x - y) (5x+y)</span>

Answer:

C. Fail to Reject H0.

Step-by-step explanation:

If the P-value is 0.06, that means that the result enters in the acceptance region. It is a value that is expected to happen if both proportions are equal (null hypothesis) at this significance level.

The conclusion when the P-value is bigger than the significance level is that the effect is not significant and it failed to reject the null hypothesis.

The best estimate would be (-1)(1/2)(-1)(1)

Why?
(-4/5) = Really close to -1. The fraction -5/5 would = -1
(3/5) = Really close to 1/2
(-6/7)  = Really close to -1. It is just -1/7 from being from -1
(5/6) = Really close to 1. It is just 1/6 from being 1

if one inch represents 14 feet how many inches would you use to make a scale drawing of a building that is 199 feet
faltersainse [42]

Answer:

14.21 inches

Step-by-step explanation:

Given

1 inch = 14 feet

Required

Find the equivalent of 199 feet

Write out the given expression;

1 inch = 14 feet

Let x represent the equivalent of 199 feet in inches; Such that:

x = 199 feet

Write out both expressions

1 inch = 14 feet

x = 199 feet

Using cross multiplication; both expressions become

x * 14 feet = 199 feet * 1 inch

Divide both sides by 14 feet

\frac{x * 14 feet}{14 feet} = \frac{199 feet * 1 inch}{14 feet}

\frac{x * 14}{14} = \frac{199* 1 inch}{14}

\frac{14x}{14} = \frac{199* 1 inch}{14}

x = \frac{199* 1 inch}{14}

x = \frac{199inch}{14}

x = 14.2142857143inch

x  = 14.21 inches (Approximated)
