At Venn diagram there are 4 parts (20 pieces):
1. Colored only in blue - quadrilaterals with four equal side lengths (3 pieces);
2. Colored only in orange - quadrilaterals with four right angles (6 pieces);
3. Colored in both blue and orange - quadrilaterals with four right angles and with four equal side lengths (2 pieces);
4. Colored in white - quadrilaterals withoutprevious two properties (9 pieces).
Consider events:
A - a randomly chosen quadrilateral has four right angles;
B - a randomly chosen quadrilateral has four equal side lengths;
Use formula
to find the probability that a randomly selected quadrilateral with 4 right angles also has four equal side lengths:
![Pr(A\cap B)=\dfrac{2}{20},\\Pr(A)=\dfrac{8}{20},\\Pr(B|A)=\dfrac{\frac{2}{20}}{\frac{8}{20}} =\dfrac{2}{8}=\dfrac{1}{4} =0.25](https://tex.z-dn.net/?f=%20Pr%28A%5Ccap%20B%29%3D%5Cdfrac%7B2%7D%7B20%7D%2C%5C%5CPr%28A%29%3D%5Cdfrac%7B8%7D%7B20%7D%2C%5C%5CPr%28B%7CA%29%3D%5Cdfrac%7B%5Cfrac%7B2%7D%7B20%7D%7D%7B%5Cfrac%7B8%7D%7B20%7D%7D%20%3D%5Cdfrac%7B2%7D%7B8%7D%3D%5Cdfrac%7B1%7D%7B4%7D%20%3D0.25%20%20%20%20)
Answer: Pr=0.25
Answer:
hello your question is incomplete attached below is the missing data
answer : Y = 206.0859 - 1.3191 X
Step-by-step explanation:
Determine the regression equation using the data on revenue and distance
The regression line equation is written as :
Y = 206.0859 - 1.3191 X
applying the regression equation to data given to determine the value of Y and residual value
The output of the the equation 3+7+8=212473 i this we first multiply the 1st and the 2nd number then we multiply the 1st and the 3rd number,then we add the result of the two output and deduct with the last number (i.e 8) and then we reverse the output to get the whole answer.
Step-by-step explanation:
<u>Step 1</u>
We have been given that
3+5+6 = 153058
5+5+6 = 253094
5+4+7 = 202874
2+6+9 = 125455
3+7+8=212473
<u></u>
<u>Step 2</u>
1. Multiply 1st and 2nd number (ignore the signs of summation) and the result makes the first two digits of the resultant 6-digit number.
(i.e. 3*7=21)
<u>Step 3</u>
Multiply 1st and 3rd number, which makes the following two digits
For example :( 3*8=24)
<u>Step 4</u>
Now add the two results you got from the multiplications step 1 and 2
i.e. 21+24=45
<u>Step 5</u>
Now subtract the result obtained in step 4 from the 3rd number on the left side of the equation.
i.e. 45-8=37
<u>Step 6</u>
Now switch places of the digits, obtained in the result and there you have it, the last two digits. (i.e. 73)
<u>Step 7</u>
<u></u>
<u>so the final answer is </u>3+7+8=212473
<span><u><em>Answer:</em></u>
C) twenty-eight and nine tenths
<u><em>Explanation:</em></u>
We have two parts here, the whole number and the decimal part.
<u>1- for the whole number,</u> it is read normally as counting numbers. Therefore, 28 is read as twenty-eight
<u>2- for the decimal part, </u>it is read based on the place-value of the number. We know that the first number after the decimal point is in the tenth position. This means that 0.9 is read as nine tenths
<u>Combining the two,</u> we would conclude that 28.9 is read as twenty-eight and nine tenths
Hope this helps :)</span>
The answer would be C. because 1 fourth of the bows would be 40 and 16 times 2 plus 8 is 40.
