Answer: 7 pigeons sitting on the branches,  5 pigeons under the tree

=12 in total

Step-by-step explanation:

Upper branch has x pigeons, lower has y.

Top branch said: "If one of you flies up to us our number will be double yours":

Well, if one of the bottom branch flies up, the top branch will have x+1 birds and the bottom will have (y−1). The top will have double the bottom, so:

x+1=2(y−1)

Top branch said: "If one of us flies down to you, our numbers will be equal":

Now, the top branch will have x−1 and the bottom y+1. The numbers should be equal:

x−1=y+1

The coordinate grid shows points A through K. What point is a solution to the system of inequalities? y < −2x + 10 y < 1 o
VashaNatasha [74]

The graph that represents the system of inequalities will be y ≤ −2x + 3; y ≤ x + 3

<h3>How to depict the graph?</h3>

The equation of the line will be:

y = mx + b

In this case, we can observe that both lines have the same y intercept and that the lines are solid.

Hence, graph that represents the system of inequalities will be y ≤ −2x + 3; y ≤ x + 3. The graph is attached.

When the coordinate grid shows points A through, the point that is a solution to the system of inequalities is negative 6 point G at negative 3, negative 10 point H at negative 4.

Finally, the graph that represents the following system of inequalities: y ≤ −3x + 1 y ≤ 1 over 2x + 3 is the graph of two intersecting lines where both lines are solid.

One line of x passes through points negative 2, 2 and 0, 3 and is shaded above the line. The other line g of x passes through points 0, 1 and 1, negative 2 and is shaded above the line.

Determine the slope of the line passing through the points (5,6) and (-5,-1)m=____
EleoNora [17]

GIVEN:

We are given two points on a line and these are;

A=(5,6),\text{ }B=(-5,-1)

Required;

We are required to determine the slope of the line passing through these points.

Step-by-step solution;

The slope of a line is given by the formula;

m=\frac{y_2-y_1}{x_2-x_1}

The variables are;

\begin{gathered} (x_1,y_1)=(5,6) \\  \\ (x_2,y_2)=(-5,-1) \end{gathered}

We can now substitute these into the formula and then simplify;

\begin{gathered} m=\frac{-1-6}{-5-5} \\  \\ m=\frac{-7}{-10} \\  \\ m=\frac{7}{10} \end{gathered}

ANSWER:

The slope of the line passing through the given points is;

m=\frac{7}{10}

Construct the 99% confidence interval estimate of the population proportion p if the sample size is n=900 and the number of succ
oee [108]

Answer:

An 99% confidence interval  of the given proportion

(0.355 , 0.385)

Step-by-step explanation:

Given sample size n= 900

the number of successes in the sample is x=333

The proportion P = \frac{x}{n} = \frac{333}{900} = 0.37

            Q = 1-P =1 - 0.37 = 0.63

<u>Confidence interval</u>:-

99% of confidence interval zα = 2.93

(P - z_{\alpha } \sqrt{\frac{PQ}{n} }  , P + z_{\alpha } \sqrt{\frac{PQ}{n} })

(0.37 - 2.93 \sqrt{\frac{0.37(0.63}{900} }  ,0.37 +2.93 \sqrt{\frac{0.37(0.63}{900} } })

(0.37 - 0.015 , 0.37 + 0.015)

(0.355 , 0.385)

<u>Conclusion</u>:-

<u>An 99% Confidence interval (0.355 , 0.385)</u>
