Imagine that Dr. Jones publishes a study that claims that drinking while pregnant is dangerous for the health of the unborn baby

Lilit [14]

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.

If 24 marks is 60% what is full marks

Luda [366]

If 24 marks is 60 %, then full marks is 40

<em><u>Solution:</u></em>

Given that 24 marks is 60 %

We are asked to find the full marks

Let the full marks be "x"

So out of "x" marks, he has got 24 marks

Therefore,

60 % of full marks = 24

60 % of x = 24

$60 \% \times x = 24\\\\\frac{60}{100} \times x = 24\\\\0.6x = 24\\\\x = \frac{24}{0.6}\\\\x = 40$

Therefore, full marks is 40

<h3><u>Method 2:</u></h3>

If 60 % is 24, then we have to find what is 100 %

60 % = 24

100 % = x

This forms a proportion, So we can solve the sum by cross multiplying

$60 \% \times x = 24 \times 100 \% \\\\60x = 2400\\\\x=\frac{2400}{60}\\\\x = 40$

Thus full marks is 40

Find the coordinates of the circumcenter for triangle DEF with coordinates D(1,3) E(8,3) and F(1,-5) show your work

nikklg [1K]

One leg is horizontal, on the line y=3. Another leg is vertical, on the line x=1. The point where these intersect, D(1, 3) is the vertex of a right angle. Any right triangle inscribed in a circle has its hypotenuse as the diameter of the circle.

Since the triangle is a right triangle, the circumcenter is the midpoint of the hypotenuse: ((8, 3) + (1, -5))/2 = (4.5, -1).
