Answer: +4/3

Explanation: It's important to understand that dividing by a fraction

means the same thing as multiplying by the reciprocal of that fraction.

In other words, we can simply change the division symbol

to multiplication and flip the second fraction.

So we can rewrite this problem as -2/3 · -2/1.

We can't cross-cancel anything.

Before multiplying, take note of your signs.

A negative times a negative is a positive,

so we know that our answer will be positive.

Multiplying across the numerators and denominators, we have +4/3.

Answer:

Kindly check explanation

Step-by-step explanation:

Dr. Jones conclusion was based on probability which measures the degree of likelihood of an occurrence or event. In his experiment, the result could be interpreted using point estimate to mean that ; 78/100 = 0.78 or 78% of those who drank while pregnant has problem with attention while only 29/100 = 0.29 or 29% of those who did not drink.

This conclusion means that pregnant women who drink have a higher likelihood of giving birth to a child with attention problem than pregnant women who do not drink. Hence, the fact that someone who drank gave birth to a perfectly healthy child does not discredit or annull Dr. Jones study.

You can print a copy of the graph, stick a pin in the origin, and rotate it 180° to see where the figure ends up.

The origin is the midpoint between each vertex and its image.
Negate every coordinate value, for example, J(-5, -3) gets rotated to J'(5, 3).
