Answer:

7/8

Step-by-step explanation:

In order to solve this problem, we need to find a common denominator, which is basically the least common multiple of the two denominators.

The two denominators are 8 and 4, and their LCM is 8. So, let's convert all these fractions so that their denominators are 8.

3/8 is already there, so we don't need to touch that.

To make 2/4 have a denominator of 8, we need to multiply the numerator and denominator by 2: (2 * 2)/(4 * 2) = 4/8

Now, we add: (3/8) + (4/8) = 7/8

That's why the answer is 7/8.

Hope this helps!

Answer:

7/8

Step-by-step explanation:

To add fractions, we need a common denominator

The common denominator of 4 and 8 is 8.

3/8 already has the common denominator.

Multiply 2/4 by 2/2 to get the common denominator

2/4*2/2=4/8

Now we have common denominators and can add

3/8+4/8

Add the numerators, and leave the denominator as is

7/8

Hope this helps! :)

When dealing with the number of occurrences of an event over a specified interval of time or space and when the occurrence or no

jeyben [28]

Answer:

POISSON DISTRIBUTION

Step-by-step explanation:

When dealing with the number of occurrences of an event over a specified interval of time or space, the poisson distribution is often useful.

Poisson distribution is applicable if:

The probability of the occurrence of the event is the same for any two intervals of equal length.

The occurrence or nonoccurrence of the event in any interval is independent of the occurrence or nonoccurrence in any other interval.

The probability that two or more events will occur in an interval approaches zero as the interval becomes smaller.

Therefore, the appropriate probability distribution is POISSON PROBABILITY DISTRIBUTION.

A house is built on coordinates (2,9). There is a water pipeline that runs along the line y = 2 3 x – 1. What is the approximate

Basile [38]

Answer:

7.21 units

Step-by-step explanation:

The shortest length needed to connect the house to the existing pipeline is the perpendicular distance between the location of the house (2,9) and the line y = 2/3x - 1.

The perpendicular distance (d) between a point ( $x_1,y_1$ ) and the line Ax + By + C = 0 is given as:

$d=\frac{|Ax_1+By_1+C|}{\sqrt{A^2+B^2} }$

The line is given by y = 2/3 x - 1; 2/3x - y - 1 = 0. The point = (2, 9)

hence A = 2/3, B = -1, C = -1, $x_1=2,y_1=9\\$ . Therefore:

$d=\frac{|\frac{2}{3}(2)+(-1)(9)+(-1) |}{\sqrt{\frac{2}{3}^2+(-1)^2 } } \\\\d=7.21$
