WILL GIVE BRAINIEST what is the sum of the interior angles of the polygon shown below.

Answer:

No

Step-by-step explanation:

The given point does not satisfy the first equation.

 y = -8(3) -3 = -27

 4 ≠ -27 . . . . . the first equation is not satisfied.

Answer: No

Step-by-step explanation:

Plug x and y into y=-8x-3 and calculate:

4 = -24 - 3

4 ≠ 27

Therefore (3,4) is not a solution of the system of equations.

Answer:

36

Step-by-step explanation:

My explanation to this is that if you look at the problem it will show you 36.

Answer:

9

Step-by-step explanation:

To find the x-intercept, set y = 0

0 = 4x-36

Add 36 to both sides:

0+36 = 4x-36+36

36 = 4x

Divide by 4 on both sides:

36/4 = 4x/4

9 = x

The x-intercept is 9

Answer:

it would only be 8, unless you need to go down to the decimal point then it would be 8.25

Step-by-step explanation:

it would be 8 because if you need to find how many bananas you have, to do this you would divide 15 by 2 and get 7.5 then you multiply those by 5 to get the number of bananas which would be 37.5, and then if 8 mangos = 30 bananas you only have 8 mangos.

(sorry if this is very jumbled and hard to understand, also getting brainliest would help, thank you)

Problem 1

Operation = Subtraction

Estimated answer = 8 dollars

----------------------------

Explanation:

The regular price is estimated at $45, while the sale price is estimated at $37. The two subtract to get 45-37 = 8 dollars, which is about how much you save if you go for the discount price.

The actual amount saved is 45.32-36.50 = 8.82

==========================================================

Problem 2

Operation = Division

Estimated answer = 75 cents

----------------------------

Explanation:

$3.45 rounds to $3

Divide this over 4 to get 3/4 = 0.75, meaning each battery is 75 cents

The actual cost per battery is 3.45/4 = 0.86 dollars = 86 cents.

==========================================================

Problem 3

Operation = Division

Estimated answer = $10

----------------------------

Explanation:

Round $37.45 to the nearest ten to get $40; we could round to 37 but that's an oddball number in my opinion compared to 40. Plus 40 is divisible by 4, leading to 40/4 = 10. Each person chips in about 10 dollars.

The actual amount each person pays is 37.45/4 = 9.36

==========================================================

Problem 4

Operation = Multiplication

Estimated answer = 180 miles

----------------------------

Explanation:

18.75 rounds to 20, which we multiply by 9 to get 180

So the car can travel about 180 miles on 9 gallons. This is an overestimate because 18.75 rounded up to 20

The actual value is 18.75*9 = 168.75

-10°C is lower than -9°C

Step-by-step explanation:

Answer:

f(x) = 5*sin( (5/4)*x) + 2

Step-by-step explanation:

A general sine function can be written as:

f(x) = A*sin(w*x) + M

Where:

A is the amplitude

w is the frequency of the function

M is the midline

Here we know that we want to have:

An amplitude of 5. Then, A  = 5

A midline of 2, then M = 2

And a period of (8/5)*pi

For now, we can write our function as:

f(x) = 5*sin(w*x) + 2

Now, we know that for a function of period T, is always true that:

f(x) = f(x + T)

here, the period is T = (8/5)*pi

knowing that sin(0) = sin(2*pi)

Then we must have:

sin(0) = sin(w*0) = sin(w*( 0 +  (8/5)*pi)) = sin(2*pi)

Then the arguments of the third and fourt parts must be the same, thus:

w*(8/5)*pi = 2*pi

We can solve this for w now:

w*(8/5) = 2

w = 2*(5/8) = (5/4)

Then the function is:

f(x) = 5*sin( (5/4)*x) + 2

Answer:

The percent decrease in the number of people who went to the pool over these four​ weeks was of 20%.

Step-by-step explanation:

Percent decrease:

The percent decrease is the decrease multiplied by 100 and divided by the initial value.

Decrease was of:

Second week: - 125

Third week: - 125 + 145

Fourth week: -125 + 145 - 224 = -204

Decrease was of 204.

Percent decrease:

Initially 1,020, then a decrease of 204. So

204*100%/1020 = 20%

The percent decrease in the number of people who went to the pool over these four​ weeks was of 20%.

Work Shown:

A = pi*r^2

A = 3.14*13^2

A = 3.14*169

A = 530.66 square millimeters

We can abbreviate "square millimeters" into "square mm" or into "mm^2".

This value is approximate because pi = 3.14 is approximate.

Answer: f(3)=g(3)

Step-by-step explanation:

The graphs intersect at x = 3.

The statement "f(6) = g(3)" is true.The correct option is A.

A graph is a structure that amounts to a set of items where some pairs of objects are in some manner "related" in discrete mathematics, more specifically in graph theory.

From the graph, we can see that the value of f(6) is 2, and the value of g(3) is also 2.

The statement "f(3) = g(3)" may or may not be true, as we do not know the values of f(3) and g(3) from the graph.

The statement "f(3) = g(6)" is not true, as the value of f(3) on the graph is -2, and the value of g(6) is 4.

The statement "f(6) = g(6)" is also not true, as the value of f(6) on the graph is 2, and the value of g(6) is 4.

Step-by-step explanation: I just had this question

The statement : "for a sample size of n = 26 and a population parameter of  p = 0.6, a normal curve can be used to approximate the sampling distribution" is true.

Normal curve is used to represent the class shapes in the statistical probability. Mathematically, we can describe the normal curve as -

[tex]$f(x)= {\frac{1}{\sigma\sqrt{2\pi}}}e^{- {\frac {1}{2}} (\frac {x-\mu}{\sigma})^2}[/tex]

where -

f(x) = probability density function

σ = standard deviation

μ = mean

Given is that for a sample size of n = 26 and a population parameter of

p = 0.6, a normal curve can be used to approximate the sampling

distribution.

It is asked to identify whether the given statement regarding the normal curve is true or false. The given statement is - "for a sample size of n = 26 and a population parameter of  p = 0.6, a normal curve can be used to approximate the sampling distribution". The given statement is true.

Therefore, the statement : "for a sample size of n = 26 and a population parameter of  p = 0.6, a normal curve can be used to approximate the sampling distribution" is true.
