Answer:
- x(27 +24) or 3x(9 +8)
- 0.5(n +5) or 2.5(n/5 +1)
Step-by-step explanation:
The distributive property of multiplication over addition tells us that the product of a value and a sum will be the same as the sum of products of the value and the sum's addends. This property can be used to add or remove parentheses from an arithmetic expression.
a(b +c) = ab +ac . . . . expression of the distributive property
__
When applying the distributive property to a sum, the first step is to look for a factor common to the terms of the sum. That factor need not be the greatest common factor, though it is often useful if it is.
Below, we have written each expression using two different common factors.
<h3>a)</h3>
27x +24x = x(27 +24) = 3x(9 +8)
__
<h3>b)</h3>
0.5n +2.5 = 0.5(n +5) = 2.5(n/5 +1)
_____
<em>Additional comment</em>
Finding a common factor can make use of knowledge of multiplication tables, rules of exponents, and identities involving various functions used in algebraic expressions. It is sometimes useful to list the prime factors of each of the terms as an aid to finding a common one. Where fractions are involved, it is sometimes helpful to express them all using a common denominator.
The Euclidean Algorithm can also be useful for finding common factors.
Answer:
Step-by-step explanation:
Given
x 2 4 6 8
y 1 -2 -5 -8
Required
Determine the slope
First, pick any two corresponding x and y values.
The slope (m) is then calculated using:
Substitute in, the x and y values
Divide numerator and denominator by 3
<em>Hence, the slope is -3/2</em>
The statement " only the estimate intercept is statistically significant at the 5% level is wrong" is wrong about the estimate.
<h3>What is probit regression?</h3>
A probit model is a type of regression in statistics where the dependant variable can only take two values.
We have:
Regress smoker on cubic polynomials of age
If we use linear probability model.
Here the data are missing, but we can say about the estimate that:
Only the estimate intercept is statistically significant at the 5% level is wrong,
Thus, the statement " only the estimate intercept is statistically significant at the 5% level is wrong" is wrong about the estimate.

I think it’s -8x + 24
Could be wrong, but I hope it helps :)
Answer:
135 degrees
Step-by-step explanation:
A triangle is 180 degrees and because the triangle has a 90 degree and an 45, it would add up to 135 and 180 minus 135 is 45.
