A rectangular flower garden in Samantha’s backyard has 260 feet around its edge the with garden is 60 What is the length of the garden

Answer:

The number of heads observed is 121.14 heads

Step-by-step explanation:

The formula for the z-score of a proportion is given as follows;

[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{pq}{n}}}[/tex]

Where:

[tex]{\hat{p}[/tex] = Sample proportion

p = Population success proportion = 0.5

q = 1 - p = 1 - 0.5 = 0.5

n = Number in of observation = 200

z = 2.99

Hence, we have;

[tex]z=\dfrac{\hat{p}-0.5}{\sqrt{\dfrac{0.5 \times 0.5}{200}}} = 2.99[/tex]

Therefore;

[tex]{\hat{p}-0.5}{} = 2.99 \times \sqrt{\dfrac{0.5 \times 0.5}{200}} = 2.99 \times\dfrac{\sqrt{2} }{40}[/tex]

[tex]{\hat{p}[/tex] = 0.6057

[tex]Whereby \ \hat p = \dfrac{Number \ of \ heads}{Number \ of \ observation} = \dfrac{Number \ of \ heads}{200} = 0.6057[/tex]

∴ The number of heads observed = 200 × 0.6057 = 121.14 heads.

Answer:

27/36.

Step-by-step explanation:

By definition, the tangent function is defined as the ratio of the side opposite to the angle to the side adjacent to the angle (opp/adj).

From angle C, the opposite side is 27, and the adjacent side is 36. We can say that tan C = 27/36.

Answer:

Sample data - subset of the total population from which estimates about the  population can be made

Point estimate - an estimate that is a single number which is represented as a  point on a line

Interval estimate - a range of values within which a true mean will fall

Hope this is correct :)

Answer:

The value of f(5) is:

-8

Step-by-step explanation:

Lets make  table which represents the function.

Th table has 2 columns, first column contains values for x, second column contains values of y

The table has 4 rows, which means that there are 4 values of x, which corresponds to 4 values of y.

The table is given as:

x          f(x)

-4         -2

-1           5

3           4

5          -8

We need to find the value of f(5).

We can get the value of f(5) if we substitute x = 5 into f(x)

We can see in the table, that if we substitute x=5 in f(x), we get the value of f(5) = -8

Which is the answer

Answer:

F(5)=8

Step-by-step explanation:

Answer:

See the explanation.

Step-by-step explanation:

The Pythagorean theorem states that a^2 + b^2 = c^2, where a and b are the legs of the triangle and c is the hypotenuse (diagonal, longest side) of the triangle.

We can see that the legs are labeled 15 (blue) and 8 (red). Substitute that into the equation.

(8)^2 + (15) ^2 = c^2

From there, we can simplify and solve for c.

64 + 225 = c^2. Add.

289 = c^2. Take the square root.

c = 17.

I hope this helps!

Answer: 17

Pro tip: 3/4/5, 5/12/13 and 8/15/17 are the first three Pythagorean Triples on the list and teachers like to use them for problems.  The multiples also come up, like 6/8/10.  Learn these and save yourself some calculation down the road.

Let's do it like they want

a² + b² = c²

8² + 15² = c²

64 + 225  = c²

289 = c²

√289 = √c²

17 = c

Answer:

x = 25

Step-by-step explanation:

The sum of the angles of a triangle are 180 degrees

2x+ x+15 +90 = 180

Combine like terms

3x+ 105 = 180

Subtract 105 from each side

3x+105-105 = 180-105

3x = 75

Divide each side by 3

3x/3 = 75/3

x = 25

The value of X is 25 degree.

Answer:

80 degrees

Step-by-step explanation:

Co-interior angles

The measure of y is 80 degree.

Option D is correct.

The basic qualities listed below make it simple to identify parallel lines.

As, from the property of parallel line we have

As, DE || XY then

y+ 100 = 180 ( Angles on same side of transversal)

y= 180- 100

First of all, what graph and second, what is "shown below"

The graph will be a line that passes through these points. In this case, the line will have a positive slope of 3 and a y-intercept of 1. None of the options is correct.

The graph of the equation y = 3x + 1 is a straight line.

To graph this equation, we need to plot points that satisfy the equation and then connect those points to create the line.

We can choose any values for x and calculate the corresponding y values using the equation. Let's choose a few x-values to get started:

When x = 0:

y = 3(0) + 1 = 1

So we have the point (0, 1).

When x = 1:

y = 3(1) + 1 = 4

So we have the point (1, 4).

When x = -1:

y = 3(-1) + 1 = -2

So we have the point (-1, -2).

We can continue this process and plot more points to have a clear representation of the line.

Once we have a few points, we can connect them with a straight line.

The resulting graph will be a line that passes through these points. In this case, the line will have a positive slope of 3 and a y-intercept of 1. Since Kesley draws the wrong x-intercept.

Answer:

[tex]9*10^{12}km[/tex]

Step-by-step explanation:

[tex]9,460,730,472,580.8 km[/tex]

First, we can work out 5% of our number, by multiplying it by 0.05

[tex]9,460,730,472,580.8 * 0.05 = 473,036,523,629[/tex]

Now, if we add and subtract our 5% calculated from our original number, we can work out the minimum and maximum value that our final answer can be in the range of.

[tex]9,460,730,472,580.8 + 473,036,523,629 = 9.933767*10^{12}\\9,460,730,472,580.8 - 473,036,523,629 =8.98769395*10^{12}[/tex]

We can see that [tex]9*10^{12}[/tex] is in the range of valid answers, as:

[tex]8.9*10^{12} \leq 9*10^{12} \leq 9.9 * 10^{12}[/tex]

So, our final answer is:

[tex]9*10^{12}km[/tex]

Answer:

slope = - [tex]\frac{2}{9}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

2x + 9y = - 18 ( subtract 2x from both sides )

9y = - 2x - 18 ( divide all terms by 9 )

y = - [tex]\frac{2}{9}[/tex] x - 2 ← in slope- intercept form

with slope m = - [tex]\frac{2}{9}[/tex]

b) Coordinates of vertex = (0, 4)

Step-by-step explanation:

Given:

Focus of parabola is [tex](0,7)[/tex] and the directrix is [tex]y=1[/tex]

To sketch: the parabola

To find: coordinates of the vertex

Solution:

As the focus lies on the y-axis and y-coordinate of the focus is positive,

equation of parabola is [tex](x-h)^2=4p(y-k)[/tex]

Here, [tex](h,k)[/tex] denotes the vertex of parabola, focus is [tex](h,k+p)[/tex] and the directrix is [tex]y=k-p[/tex]

According to question,

[tex](h,k+p)=(0,7)[/tex]

[tex]k-p=1[/tex]

So, [tex]h=0[/tex]

[tex]k+p=7\,,\,k-p=1[/tex]

On adding these equations,

[tex]k+p+k-p=7+1\\2k=8\\k=4[/tex]

Put [tex]k=4[/tex] in [tex]k+p=7[/tex]

[tex]4+p=7\\p=7-4\\p=3[/tex]

So, equation of parabola is [tex](x-0)^2=4(3)(y-4)\Rightarrow x^2=12(y-4)[/tex]

For part a), see the attached file.

b)

Coordinates of vertex = [tex](h,k)=(0,4)[/tex]
