Step-by-step explanation:

Answer:

y = -2.5x +100

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

We need to solve for y

25x+ 10y =1000

Subtract 25x from each side

25x-25x+10y = -25x +1000

10y = -25x+1000

Divide each side by 10

10y/10 = -25x/10 +1000/10

y = -2.5x +100

Answer:

y = -2.5x + 100

Step-by-step explanation:

25x + 10y = 1,000

10y = -25x + 1000

y = -2.5x + 100

Answer:

C

Step-by-step explanation:

to find 4, you use the equation [tex]a^{2}+b^{2}=c^{2}[/tex] where the c= hypotenuse, which is the slant of the triangle. Then you width and length can by put as a and b. This gives you [tex]15^{2}+4^{2} = s^{2}[/tex]. Then you solve for s which end up being 15.5.

Answer:

[tex]29.5-1.671\frac{5.2}{\sqrt{59}}=28.37[/tex]    

[tex]29.5+1.671\frac{5.2}{\sqrt{59}}=30.63[/tex]    

And we can conclude that the true mean for the scores are given by this interval (28.37; 30.63) at 90% of confidence

Step-by-step explanation:

Information given

[tex]\bar X = 29.5[/tex] represent the sample mean

[tex]\mu[/tex] population mean  

s= 5.2 represent the sample standard deviation

n=59 represent the sample size  

Confidence interval

The confidence interval for the true mean is given by the following formula:

[tex]\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}[/tex]   (1)

The degrees of freedom are given by:

[tex]df=n-1=59-1=58[/tex]

The Confidence interval is 0.90 or 90%, the significance is [tex]\alpha=0.1[/tex] and [tex]\alpha/2 =0.05[/tex], and the critical value is [tex]t_{\alpha/2}=1.671[/tex]

Now we have everything in order to replace into formula (1):

[tex]29.5-1.671\frac{5.2}{\sqrt{59}}=28.37[/tex]    

[tex]29.5+1.671\frac{5.2}{\sqrt{59}}=30.63[/tex]    

And we can conclude that the true mean for the scores are given by this interval (28.37; 30.63) at 90% of confidence

First Part:

The minimum value is -0.75

The maximum value is 0.75

Second Part:

The amplitude is 0.75

Third Part:

An equation for this function is y = 0.75cos(x)

The minimum value of the graph is -0.75 and maximum value is 0.75, amplitude is 0.75, and function for the graph is y = 0.75cosx.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a graph shown in the picture.

From the graph, we can see that:

The minimum value = -0.75

The maximum value = 0.75

The amplitude = 0.75

And the graph of the function:

y = 0.75cosx

Where y ∈ [-0.75, 0.75]

Thus, the minimum value of the graph is -0.75 and maximum value is 0.75, amplitude is 0.75, and function for the graph is y = 0.75cosx.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

The intercepts are:

The x-intercept is the point of the line when y = 0,

The y-intercept is the point on the line when x = 0.

Now,

Apply the intercepts concept on the given graph.

From the graph,

The point when x = 0 is 0.4.

The point when y = 0 is 0.3.

Thus,

The x-intercept of the graph is (0.3, 0).

The y-intercept of the graph is (0, 0.4).

Answer:

y = (-1/4)x + 3

Step-by-step explanation:

The slope of our equation is 4, so to find the slope of the perpendicular equation, we have that:

m1 * m2 = -1

Where m1 is the slope of the first equation and m2 is the slope of the perpendicular equation.

So, we have that:

4 * m2 = -1

m2 = -1/4

So the second equation is y = (-1/4)x + b

If the second equation goes through the point (4,2), for x = 4 we have y = 2, then:

2 = (-1/4)*4 + b

2 = -1 + b

b = 3

So the perpendicular equation is:

y = (-1/4)x + 3

The given expression can be solved as -3/5.

The given expression is  [tex]\sqrt[3]{\frac{-27}{125} }[/tex].

Here, 27 and 125 can be written as

27 = 3×3×3 = 3³

125 = 5×5×5 = 5³

Now, [tex]\sqrt[3]{\frac{-3^3}{5^3} }= ({\frac{-3^3}{5^3})^{\frac{1}{3} }[/tex]

= -3/5

Therefore, the given expression can be solved as -3/5.

Answer:

(2,-1)

Step-by-step explanation:

Multiply first equation by 2:

10x + 2y = 18

Subtract the second equation from this so that the 2y terms cancel:

10x - 3x = 18 - 4

7x = 14

x = 2

Plug into first equation to find y:

5(2) + y = 9

10 + y = 9

y = -1

The answer is (2,-1)

Answer:

300 centimeters ( cm)

Step-by-step explanation:

The operation is   "multiply by 100 the numbers of  meters because there are 100 cm in 1 m "

1m=100 cm

3m=3*100 cm=300 cm

There are 100 centimeters in a meter, resulting in 300 centimeters.

The operation needed to convert meters to centimeters is multiplication because there are 100 centimeters in 1 meter. To convert 3 meters to centimeters, you simply multiply 3 meters by the conversion factor of 100 centimeters per meter.

Therefore:

3 meters × 100 centimeters/meter = 300 centimeters

Using this operation and knowing the conversion factor, we find that 3 meters is equal to 300 centimeters.
