C-3d = 11
-2c + 3d = -16

Answer: D. [tex]y=\frac{1}{9} x^{2}[/tex]

Step-by-step explanation: The smaller the coefficient of a fraction by the quadratic function (the x squared value), the more narrow the graph becomes. 1/4 is larger than 1/9 and the other two whole numbers are still larger than 1/9. Even though -1 is less than 1/9, this only makes the graph flip, not make it any more narrow. Fractions are what squeeze graphs, negatives do not make a difference (i.e. -1/4 is the same size of narrowness as 1/4).

Answer:

768

Step-by-step explanation:

Volume is base times height. To find the base, we can see that it is a triangle. Sure! 8 times 12 would be 96, and divide that by 2 to get 48. That would be the area of the triangle.

To find the volume, all we need to do is multiply by 16. 48 times 16 is 768.

Answer:

n = -5 or -6

Step-by-step explanation:

[tex]n^2+ 11n + 30 = 0[/tex]

Lets factorise the quadratic equation :-

→ Lets split the middle term of the equation.

[tex]=> n^2 + 5n + 6n + 30 = 0[/tex]

→ Lets take 'n' common from the first 2 terms & '6' common from last 2 terms.

[tex]=> n(n + 5) + 6(n + 5) = 0[/tex]

→ Lets take (n + 5) whole in common from the equation.

[tex]=> (n + 5)(n + 6) = 0[/tex]

Here , we get 2 values of n :-

1) [tex]n + 5 = 0[/tex]

[tex]=> n = -5[/tex]

2) [tex]n + 6 = 0[/tex]

[tex]=> n = -6[/tex]

∴ Hence , n = -5 or -6

c=6g+5 (this is the answer to problem on screen)

The question asks for how much it costs for g games not 9 games. Though solving for 9 games is simple

c(9)=6(9)+5

c(9)=54+5

c(9)=$59

Answer:

0.2835 = 28.35% probability that an average person makes at least one MONTHLY visit to doctors' office and hospitals

Step-by-step explanation:

Mean during a time period means that we use the Poisson distribution.

Poisson distribution:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

In which

x is the number of sucesses

e = 2.71828 is the Euler number

[tex]\mu[/tex] is the mean in the given interval.

It is estimated that an average person makes four visits a year to doctors' offices and hospitals.

A year has 12 months, which means that the monthly mean is [tex]\mu = \frac{4}{12} = \frac{1}{3}[/tex]

What is the probability that an average person makes at least one MONTHLY visit to doctors' office and hospitals?

This is:

[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]

In which

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-(\frac{1}{3})}*(\frac{1}{3})^{0}}{(0)!} = 0.7165[/tex]

[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.7165 = 0.2835[/tex]

0.2835 = 28.35% probability that an average person makes at least one MONTHLY visit to doctors' office and hospitals

Answer:

The sum of the first 41 terms is 6232

Step-by-step explanation:

The sequence is an arithmetic progression with:

[tex]a = 12[/tex] -- first term

[tex]d = 7[/tex] --- common difference (this is calculated by 19 - 12 or 26 -19)

Required

The sum of the first 41 terms

This is calculated as:

[tex]S_n = \frac{n}{2}(2a + (n-1)*d)[/tex]

In this case: [tex]n = 41[/tex]

So:

[tex]S_{41} = \frac{41}{2}(2*12 + (41-1)*7)[/tex]

[tex]S_{41}= \frac{41}{2}*304[/tex]

[tex]S_{41} = 6232[/tex]

[tex] \sqrt[9]{xy^{2} } [/tex]

this is the answer.

Answer:

The area of the circle is 531.14 square unis

Step-by-step explanation:

Area of a circle = [tex]\pi[/tex][tex]r^{2}[/tex]

where r is the radius of the circle

Given that the diameter of the circle = 26 units, the radius can be determined by;

r = [tex]\frac{diameter}{2}[/tex]

 = [tex]\frac{26}{2}[/tex]

r = 13 units

So that,

Area of the circle = [tex]\frac{22}{7}[/tex] x [tex](13)^{2}[/tex]

                             = [tex]\frac{22}{7}[/tex] x 169

                             = 531.1429

The area of the circle is 531.14 square unis.

Answer:

24oz in all so if there are 8oz in each cup then there are-- 3 cups --

Step-by-step explanation:

because 8x3=24

Answer:

One pound can be written as 1.0 pounds, and moving the decimal place one place to the left gives you 0.10 pound, which is equal to one tenth of a pound. Convert 16 oz. to one sixteenth of an ounce by moving the decimal one place to the left.

Answer:

x1 = y1 - a*y2 + (a*c - b)*y3

x2 = y2 - c*y3

x3 = y3

Step-by-step explanation:

Here we have the system:

x1 + a*x2 + b*x3 = y1

x2 + c*x3 = y2

x3 = y3

Where the variables y1, y2, and y3 are known (a, b and c are also known).

The first step is to isolate one of the variables in one of the equations, we can see that in the third equation we have x3 already isolated, so now we can just replace it on the other two equations to get:

x1 + a*x2 + b*(y3) = y1

x2 + c*(y3) = y2

Now we again want to isolate one of the variables in one of the equations, i will isolate x2 in the second equation to get:

x2 = y2 - c*y3

Now we can replace this on the other equation to get:

x1 + a*(y2 - c*y3) + b*y3 = y1

Now we canw write x1 in terms of the known variables:

x1 = y1 - a*y2 + (a*c - b)*y3

And in the process we also found that:

x3 = y3

x2 = y2 - c*y3

Then the solutions are:

x1 = y1 - a*y2 + (a*c - b)*y3

x2 = y2 - c*y3

x3 = y3
