Given point P (3, 4). What is the distance of point P from (a) x axis (b) y axis?
vova2212 [387]

Answer:

a) 3

b) 4

Step-by-step explanation:

The point P is(3,4)

which means that 3 is the point P's x- coordinate and 4 is it's y-coordinate

Because we use the axes as our reference point when plotting points,

the distance of P from x-axis and y-axis would be the point itself.

Perform the following division. Round the answer to three decimal places. 126.4 ÷ 1.7 =
kherson [118]
I am assuming that you are supposed to answer this division problem through the long division method. So my answer is going to be a step-by-step description of the long division solution for this problem.

The first step is to move the decimal point of the dividend and the divisor. Hence, 1264.0 and 17. The decimal point of the quotient shall then be written in alignment with the decimal point of the dividend.

Then we proceed with the division process, 126/17 gives us 7 (write this above the division bar). 7 multiplied by 17 gives 119 (write this under the divisor). So 126-119 is equal to 7. We then bring down the digit after 126 of the divisor, which is 4. So we now have 74. 74 divided by 17, we get 4. 4 multiplied by 17 gives 68. We subtract 68 from 74 and we have 6, bring down 0, we have 60. We then repeat the division-multiplication-subtraction process until we get to the third decimal place of the quotient.

Finally, the answer is 74.352.

involving the selection of two apples from a bag of red and yellow apples without replacement. Assume that the bag has a total o
ivolga24 [154]

Answer:

1) The probability that the second apple is red is 0.7143 (71.43%).

2) The probability that at least one red apple is picked 0.9341 (93.41%).

Step-by-step explanation:

We can make a probability tree as the attached picture.

1) There are 2 ways in the probability tree when the second apple is red:

Both apples are red:

P(R∩R)=\frac{10}{14}\frac{9}{13}=0.4945

Only the second apple is red:

P(Y∩R)=\frac{4}{14}\frac{10}{13}=0.2198

The probability that the second apple is red is the sum of the previous probabilities.

P(2nd R)=P(R∩R)+P(Y∩R)=0.4945+0.2198=0.7143

2) To find the probability that at least one apple is red, we can get the probability of none of the apples is red and then it will be subtracted from 1.

The way in the probability tree is Y∩Y:

P(Y∩Y)=\frac{4}{14} \frac{3}{13}=0.0659

P(at least 1 R)= 1-P(Y∩Y)=1-0.0659=0.9341
