Answer:

$5xy^2(y+ 3x^2- 6x)$

Step-by-step explanation:

$5xy^3 + 15x^3y^2 - 30x^2y^2$

To factor out an expression, factor out GCF

$5xy^3= 5 \cdot x \cdot y \cdot y \cdot y$

$15x^3y^2= 5 \cdot 3 \cdot x \cdot x \cdot x \cdot y \cdot y$

$30x^2y^2= 5 \cdot 2 \cdot 3 \cdot x \cdot x \cdot y \cdot y$

GCF is 5 times x times y time y

GCF is 5xy^2. Factor out GCF

$5xy^3 + 15x^3y^2 - 30x^2y^2$

$5xy^2(y+ 3x^2- 6x)$

Answer:

5xy^2(y + 3x^2 - 6x).

Step-by-step explanation:

5xy^3 + 15x^3y^2 − 30x^2y^2

The GCF is 5xy^2 so dividing through by this we get the factors:

= 5xy^2(y + 3x^2 - 6x).

The first is a right triangle because there is a right angle, and it is scalene because none of the sides are congruent.

The second is an obtuse triangle because there is an obtuse angle, and it is an isosceles triangle because two of the sides are congruent.

The third is an acute triangle because all of the angles are acute, and it is an <span>isosceles triangle because two of the sides are congruent.

Use the slope of the given line to construct a parallel line

Troyanec [42]

Answer:

y = - $\frac{4}{3}$ x - 7

Step-by-step explanation:

Parallel lines have equal slopes.

Calculate the slope m of the given line using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, - 2) ← 2 points on the line

m = $\frac{-2-2}{3-0}$ = - $\frac{4}{3}$ , thus

y = - $\frac{4}{3}$ x + c ← is the partial equation

To find c substitute P(- 3, - 3) into the partial equation

- 3 = 4 + c ⇒ c = - 3 - 4 = - 7

y = - $\frac{4}{3}$ x - 7 ← equation of parallel line

For many years businesses have struggled with the rising cost of health care. But recently, the increases have slowed due to les

Elza [17]

Answer:

The 95% confidence interval estimate of the true population proportion of U.S. employers that were likely to require higher employee contributions for health care coverage is 0.52 +/- 0.0370

= (0.4830, 0.5570)

The margin of error M.E = 0.0370

Step-by-step explanation:

Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

The confidence interval of a statistical data can be written as.

p+/-z√(p(1-p)/n)

p+/-M.E

Given that;

M.E = margin of error

Proportion p = 52% = 0.52

Number of samples n = 700

Confidence interval = 95%

z value (at 95% confidence) = 1.96

Substituting the values we have;

0.52 +/- 1.96√(0.52(1-0.52)/700)

0.52 +/- 1.96(0.0189)

0.52 +/- 0.0370

( 0.4830, 0.5570)

The 95% confidence interval estimate of the true population proportion of U.S. employers that were likely to require higher employee contributions for health care coverage is 0.52 +/- 0.0370

= (0.4830, 0.5570)

The margin of error M.E = 0.0370
