The equations x + 5 y = 10, 3 x minus y = 1, x minus 5 y = 10, and 3 x + y = 1 are shown on the graph below. On a coordinate pla

ne, there are 4 lines. Green line goes through (0, negative 1) and (1, 2). Blue line goes through (0, 1) and (1, negative 2). Pink line goes through (0, 2), and (2, 1.5). Orange line goes through (negative 2, negative 2.5) and (2, negative 1.5).

Answer:

The question is missing, so I will answer all the solution for each possible system of two equations.

Step-by-step explanation:

The equations

x + 5 y = 10 (red)

3 x - y = 1 (blue)

x - 5 y = 10 (green)

3 x + y = 1 (purple)

are shown in the picture atatched. The intersection between two lines is the solution of their system.

<u>system:</u>

x + 5 y = 10 (red)

3 x - y = 1 (blue)

<u>solution</u>: (0.938, 1.813)

<u>system</u>:

x + 5 y = 10 (red)

x - 5 y = 10 (green)

<u>solution</u>: (10, 0)

<u>system</u>:

x + 5 y = 10 (red)

3 x + y = 1 (purple)

<u>solution</u>: (-0.357, 2.071)

<u>system</u>:

3 x - y = 1 (blue)

x - 5 y = 10 (green)

<u>solution</u>: (-0.357, -2.071)

<u>system</u>:

3 x - y = 1 (blue)

3 x + y = 1 (purple)

<u>solution</u>: (0.333, 0)

<u>system</u>:

x - 5 y = 10 (green)

3 x + y = 1 (purple)

<u>solution</u>: (0.938, -1.813)

The owner of a small deli is trying to decide whether to discontinue selling magazines. He suspects that only 10% of his custome
Rainbow [258]

Answer:

0.55% probability that exactly 5 out of the first 13 customers buy a magazine

Step-by-step explanation:

For each customer, there are only two possible outcomes. Either they buy a magazine, or they do not. The probability of a customer buying a magazine is independent of other customers. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

10% of his customers buy a magazine

This means that P = 0.1

What is the probability that exactly 5 out of the first 13 customers buy a magazine?

This is P(X = 5) when n = 13. So

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 5) = C_{13,5}.(0.1)^{5}.(0.9)^{8} = 0.0055

0.55% probability that exactly 5 out of the first 13 customers buy a magazine

Twenty percent of the trees in an orchard are apple trees, and 1/3 of the trees that are not apple trees are cherry trees. If 3/
wariber [46]

Answer:

The required fraction is 17/60

Step-by-step explanation:

Consider the provided information.

Let us assume that the number number if trees are 60.

It is given that 20% are apple tree.

\frac{20}{100}\times60=12

Therefore, 12 trees are apple tree.

That means non apple trees are:

Non apple trees = 60 - 12 = 48

It is given that and 1/3 of the trees that are not apple trees are cherry trees.

Cherry trees = 1/3 × 48 = 16

The cherry trees are 16.

3/4 of the trees in the orchard are fruit trees,

Fruit trees = 3/4 × 60 = 45

Total fruit tree are 45

Plum trees = 45 - 12 - 16 = 17

Hence, the number of plum trees are 17

We need to find fraction of the trees in the orchard are plum trees

Fraction = 17/60

Hence, the required fraction is 17/60
