Answers

Answer 1
[tex]\bold{FULL ANSWER:}[/tex]
Solve The System With Elimination.x - 2y = 43x + Y = 6? ]
Answer 2
x = 16/7, y = -6/7

For elimination I will multiply the first equation by -3 to get the x to cancel

x - 2y = 4 --> -3x + 6y = -12

Now we bring back the other equation and treat it like an addition problem:

-3x + 6y = -12
3x + y = 6
+———————
7y = -6

y = -6/7

To get x we will use this y-value and plug it into one of the equations:

3x + y = 6,
3x + (-6/7) = 6
3x - 6/7 = 6
3x = 48/7
x = 16/7

So the solution is x = 16/7, y = -6/7, and if you are ever unsure you can put both of these values into both system of equations to see if the equations are true.

How would the median change if the number 71 replaced one of the 67's in the set?

71, 67, 67, 17, 69, 84, 21, 87

Question 5 options:

decrease


increase


no change

Answers

Answer:

increase

Step-by-step explanation:

Given data is: 71, 67, 67, 17, 69, 84, 21, 87

Arranging in ascending order we find: 17, 21, 67, 67, 69, 71, 84, 87

Here N = 8 (Even number)

N/2 = 4 and N/2 + 1 = 5

4th term = 67, 5th term = 69

-> median = Sum of 4th and 5th term/2 = (67 + 69)/2 = 132/2 = 66

Now, when one of the 67 is replaced by 71, the new data set in ascending order will be: 17, 21, 67, 69, 71, 71, 84, 87

Here, 4th term = 69, 5th term = 71

New median = (69 + 71)/2 = 140/2 = 70

-> new median > initial median

CONCLUSION: Median will increase if the number 71 replaced one of the 67's in the set.

Answer:

  P(X > 8) = 5/18

  P(X mod 5 ≠ 0) = 29/36

Step-by-step explanation:

You want various probabilities related to the sum of two dice.

Greater than 8

Please refer to the attached chart of possible outcomes. There are 4 ways to roll a 9, 3 ways to roll a 10, 2 ways to roll 11, and one way to roll 12. That means there are 4+3+2+1 = 10 ways to roll a number greater than 8.

 P(X > 8) = 10/36 = 5/18

Not divisible by 5

It is easier to count results that are divisible by 5. Then the difference between that number and 36 will be the number of outcomes not divisible by 5.

5 can be rolled 4 ways, and 10 can be rolled 3 ways. A total of 4+3 = 7 of the 36 outcomes are divisible by 5. That means 36 -7 = 29 are not divisible by 5.

  P(X not divisible by 5) = 29/36

The x coordinate of the midpoint is 0.

The y coordinate of the midpoint follows the same idea, but we focus on the y coordinates of course. You should find the y coordinate of the midpoint is 0.

What is the length of side AB of parallelogram ABCD?
units
4g - 8
B
q+4

Answers

Answer:

8 units

Step-by-step explanation:

» Concepts

Parallelogram Side Theorem states that the opposite sides of a parallelogram are congruent, meaning they have the same length.

» Application

In this case, we're asked to apply the theorem to find the value of q and then find the length of AB. Thus, we have to set up the equation 4q - 8 = q + 4.

» Solving

Step 1: Subtract q from both sides.

[tex]4q-8-q=q+4-q[/tex] [tex]3q-8=4[/tex]

Step 2: Add 8 to both sides.

[tex]3q-8+8=4+8[/tex] [tex]3q=12[/tex]

Step 3: Divide both sides by 3.

[tex]3q/3 = 12/3[/tex] [tex]q=4[/tex]

Step 4: Plug in the value of q for side AB.

[tex]4(4)-8[/tex] [tex]16-8[/tex] [tex]8[/tex]

Therefore, the answer is 8 units.

A rectangle prism with a length of 12.5 cm and a width of 7.5 cm has a
volume of 937.50 cm?. What is the height of the rectangular prism?

Answers

Answer:

Height = 10 cm

Step-by-step explanation:

To find the height of the rectangular prism, we need to use the volume equation of rectangular prisms:

V = l * w * h

l = length

w = width

h = height

We know the length (12.5 cm), width (7.5 cm), and the volume (937.50 [tex]cm^{3}[/tex]).

Plug all these into the equation and solve for the height:

937.50 = (12.5)(7.5)h

937.50 = 93.75h                           Multiply 12.5 by 7.5

10 = h                                             Divide 937.50 by 93.75 to get h.

Therefore, the height of the rectangular prism is 10 cm.

Let's check our answer by plugging all values into the volume equation:

937.50 = (12.5)(7.5)(10)

937.50 = 93.75 (10)                      

937.50 = 937.50                           Both values are equal so 10 is correct!

I hope this helps! Good luck!

A rectangular image of length 5 cm and width 7 cm is magnified in a studio. On magnification, 1 cm of the image represents 15cm. Find the perimeter of the rectangle in the magnified image.

Answers

Answer:

238 cm

Step-by-step explanation:

so we have a scale factor   of  17: 1

originally we had the dimensions:   3cm by 4m

now we have    3*17  by 4*17  = 51 cm by 68 cm

Perimeter = 2*51 + 2*68 = 238 cm

Answer:

360 cm

Step-by-step explanation:

The height of the magnified image is the product of the height of the original image and the scale factor.

h=15(7) cm.

Simplify.

h=105 cm.

The width of the magnified image is the product of the width of the original image and the scale factor.

w=15(5) cm.

Simplify.

w=75 cm.

So, the perimeter is

P=2(75)+2(105) cm.

Simplify.

P=360 cm.

Therefore, the perimeter of the painting is 360 cm.

Functions can be represented using equations and graphs Both f(x) and g(x) include domain values of [4, ∞) and range values of [0, ∞), and both functions have a y-intercept in common.

How to determine the key features?

The domain of the function is defined as the set of the numbers we are allowed to put in the function while the range is the assumed data put in the function.

The functions are given as:

[tex]F(x)=e^{-x}\\\\\\g(x)=-\sqrt{x-4}[/tex]

Using a graphing calculator:

The domain of g(x) is [4, ∞)

The range of g(x) is  [0, ∞)

The domain of f(x) is  (–∞, ∞),

The range of f(x) is  [0, ∞)

Both functions have positive values for their domains

By comparing the above highlights, the true statement between functions g(x) and f(x) is option 3
