The ratios of x to y is 3 to 2, and the ratio of z to y is 5 to 1. What is the ratio of x to z?

Answer:

1 & 2 = Right Triangles

3 & 4 = Not Right Triangles

Step-by-step explanation:

Solved Using Pythagorean Theorem:

1) [tex]9^{2} + 12^{2}[/tex] = 225

[tex]15^{2}[/tex] = 225

2) [tex]15^{2} + 36^{2}[/tex] = 1521

[tex]39^{2}[/tex] = 1521

3) [tex]10^{2} + 26^{2}[/tex] = 776

[tex]28^{2}[/tex] = 784

4) [tex]10^{2} + 12^{2}[/tex] = 244

[tex]16^{2}[/tex] = 256

Equation of regression line is in the form:

y = mx + c

Where y = predicted variable ;

c = intercept ; m = slope or gradient ; x = predictor variable

Using The correlation Coefficient calculator :

The regression equation obtained is :

ŷ = 0.2754X - 0.77028

Rounding values in our regression output to 2 decimal places :

y = 0.28X - 0.77

Hence best model to make prediction :

y = 0.28X - 0.77

Answer: -2

Step-by-step explanation:

The lowest point is at (-4,-2) and they are asking for the y value which is -2. C

Answer:

y = 2x - 1

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 )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = A(4, 7) and (x₂, y₂ ) = B(2, 3)

m =  =  = 2, thus

y = 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation.

Using B(2, 3), then

3 = 4 + c ⇒ c = 3 - 4 = - 1

y = 2x - 1 ← equation of line

Answer: 243.6

Step-by-step explanation:

For us to solve the question and round off 243.583 to the nearest tenth. First, we need to look at the number beside the tenth number which is 8.

Since 8 is more than 4, we simply add 1 to the tenth number which implies that we add 1 to the number in tenth place which is 5. Adding one means the number change to 6. Therefore, rounding 243.583 to the nearest tenth will be 243.6.

Answer: C. 4x is a term in 4x - 5

Step-by-step explanation: 4 is a coefficient due to being combined with x. But together, it is called a term. 5 can not be a coefficient due to it being away from x. I hope this helped.

Answer:

x=7  y=8  z=2

Step-by-step explanation:

The value of all three numbers will be 7, 8, and 2  for the given condition.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say the first number is x, the second is y and the third is z.

The sum of three numbers is 17 ⇒

x + y + x = 17

The sum of twice the first number, 4 times the second number and 5 times the third number is 56 ⇒

2x + 4y + 5z = 56

The difference between 7 times the first number and the second number is 41 ⇒

7x - y = 41 ⇒ y = 7x - 41

By substituting this y into the above equation.

A newly formed equation will be

-40x - 5z = -290

30x + 5z = 220

By solving them x = 7 and z = 2 by that y = 8

Hence all three values will be 7,2 and 8.

Answer:

8 cm

Step-by-step explanation:

Given that:

Side = 5cm

Altitude = height = 8cm

Diagonal 1 = 10cm

Diagonal 2 = d

Area of rhombus = base * height = 0.5 * (diagonal 1 * diagonal 2)

5 * 8 = 0.5 * (10 * d)

40 = 5d

Divide both sides by 5

40/5 = 5d / 5

8 = d

Length of other diagonal = 8cm
