Mathematics
1 answer:
Nostrana [21]2 years ago
5 0

Answer:

Below in bold

Step-by-step explanation:

I AM ASSUMING that CDEF is a Rhombus.

If it is than triangle DEG is right-angled.

so 2x + 18 + 5x + 2 = 90.

7x = 90 - 20 = 70

x = 7.

So m < CDF  = 5x + 2

= 5(10) + 2

= 52 degrees.

m < DCE = 2(10) + 18 = 38 degrees.

The diagonal bisects < DCF so m < ECF = 38 degrees.

So m < DCF = 2 * 38 = 76 degrees.

Opposite angles of a rhombus are equal so m < DEF = 76 degrees.

Write down the equation that could be a correct equation for linear regression prediction function?
user100 [1]

If the question meant that we should write a linear prediction function ;

Answer:

y = bx + c

Step-by-step explanation:

The equation for a linear regression prediction function is stated in the form :

y = bx + c

Where ;

y = Predicted or dependent variable

b = slope Coefficient

c = The intercept value

x = predictor or independent variable

Therefore, the Linear function Given represents a simple linear model for one dependent variable, x

b : is the slope value of the equation, whuch represents a change in y per unit change in x

AABC is isosceles.<br> AB = 3x - 4 and BC = 5x - 10.<br> AB = [?]
Schach [20]

If AB = BC then set up the equation 3x - 4 = 5x - 10

Subtract 3x.

-4 = 2x - 10

Add 10.

6 = 2x

Divide by 2.

3 = x

AB is 3x - 4 so

3(3) - 4

9 - 4

5.

AB = 5

If AB is not equal to BC then this is not solvable.

But if they are I am sure AB = 5.

Hope this helps
