Find the slope (m) by using Y2-Y1/X2-X1

Y2 = -1

Y1 = 7

X2 = 4

X1 = 2

(-1 - 7)/((4-2) = -8/2 = -4

Use the point-slope formula to determine the equation. You only need to use one set of points. (2,7) in this case.

(y-Y1) = m(x-X1)

(y - 7) = -4(x - 2)

y-7=-4x + 8

y= -4x + 15

Answer:

P(Ice Cream|Frogtown) = 67.4\%

Step-by-step explanation:

Given

The attached plot

Required

P(Ice Cream|Frogtown)

This is calculated as:

P(Ice Cream|Frogtown) = \frac{P(Ice\ Cream\ n\ Frogtown)}{P(Frogtown)}

From the attachment;

P(Ice\ Cream\ n\ Frogtown) = 0.31

P(Frogtown) = 0.31 + 0.15 = 0.46

So, we have:

P(Ice Cream|Frogtown) = \frac{P(Ice\ Cream\ n\ Frogtown)}{P(Frogtown)}

P(Ice Cream|Frogtown) = \frac{0.31}{0.46}

P(Ice Cream|Frogtown) = 0.6739

Express as percentage

P(Ice Cream|Frogtown) = 0.6739 * 100\%

P(Ice Cream|Frogtown) = 67.39\%

P(Ice Cream|Frogtown) = 67.4\% -- approximated

Which expression is equivalent to the given expression? Assume the denominator does not equal zero.
Snezhnost [94]

The simplification form of the provided expression is 2y⁴/x⁴ option (A) 2y⁴/x⁴ is correct after applying the integer exponent properties.

<h3>What is an integer exponent?</h3>

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

The question is incomplete.

The complete question is attached in the picture, please refer picture.

We have an expression:

= \rm \dfrac{\left(14x^4y^6\right)}{\left(7x^8y^2\right)}

\rm =\dfrac{7\cdot \:2x^4y^6}{7x^8y^2}

\rm =\dfrac{2x^4y^6}{x^8y^2}

\rm =\dfrac{2y^4}{x^4}

Thus, the simplification form of the provided expression is 2y⁴/x⁴ option (A) 2y⁴/x⁴ is correct after applying the integer exponent properties.
