The true statement about the quadrilateral is ABCD is a rhombus with non-perpendicular adjacent sides.

<h3>How to determine the true statement?</h3>

The coordinates are given as:

A(4, 5), B(2, 4), Q4, 3), and D(6, 4).

Next, we plot the graph of the quadrilateral ABCD

See attachment

From the attached graph, we have the following highlights:

  • Opposite sides are equal
  • Opposite sides are parallel
  • Adjacent sides are not perpendicular

This means that the quadrilateral is ABCD is a rhombus

Answer:

A.) 193

B.)191

C.)236

D.)128

Step-by-step explanation:

A)   12^2+(8-4)^3-15

       144+(64)-15

     208-15=193

B) (3*2)^3-5^2

    6^3=216-5^2

           216-25=191

I only showed work for A and B

Hope this helps !!

Answer:

x=-6

QUESTION 31

Step-by-step explanation:

3x+5=2x-1

Subtract 5 from both sides

3x+5-5=2x-1-5

Simplify

3x=2x-6

Subtract 2x from both sides

3x-2x=2x-6-2x

QUESTION 32

1/3(6x+12) = 1/2(4x-8) + 8

1/2(4x-8) = 4x-8/2 +8

1/3(6x+12) = 4x-8/2 +8

2(6x+12) = 12(x-2) + 48

12x+24

12x+24 = 12x+24

12x+24 - 24 = 12x+24 - 24

12x=12x

Click on all the values for n that make this inequality true. There may be more than one answer.
vodka [1.7K]
Equation: 120 ≥ 10n + 20

Subtract 20 from both sides, 

100 ≥ 10n

Divide both sides by 10, 
10 ≥ n

It means, it is equal or Smaller than 10.

So, the answers would be: 7, 8, 9, 10

Hope this helps!

A researcher wanted to see if giving a selective serotonin reuptake inhibitor (anti-depressant) would decrease the number of sel
Delvig [45]

Answer:

a. The mean of the sample is M=35.

The variance of the sample is s^2=39.125.

The standard deviation of the sample is s=6.255.

b. z=-1.6

c. SEM = 2.212

Step-by-step explanation:

The mean of the sample is M=35.

The variance of the sample is s^2=39.125.

The standard deviation of the sample is s=6.255.

<u>Sample mean</u>

<u />M=\dfrac{1}{8}\sum_{i=1}^{8}(27+25+32+40+43+37+35+38)\\\\\\ M=\dfrac{277}{8}=35

<u>Sample variance and standard deviation</u>

<u />s^2=\dfrac{1}{(n-1)}\sum_{i=1}^{8}(x_i-M)^2\\\\\\s^2=\dfrac{1}{7}\cdot [(27-(35))^2+(25-(35))^2+(32-(35))^2+(40-(35))^2+(43-(35))^2+(37-(35))^2+(35-(35))^2+(38-(35))^2]\\\\\\

s^2=\dfrac{1}{7}\cdot [(58.141)+(92.641)+(6.891)+(28.891)+(70.141)+(5.64)+(0.14)+(11.39)]\\\\\            s^2=\dfrac{273.875}{7}=39.125\\\\\\s=\sqrt{39.125}=6.255

b. If the population mean is 45, the z-score for M=35 would be:

z=\dfrac{M-\mu}{\sigma}=\dfrac{35-45}{6.255}=\dfrac{-10}{6.255}=-1.6

c. The standard error of the mean (SEM) of this group is calculated as:

SEM=\dfrac{s}{\sqrt{n}}=\dfrac{6.255}{\sqrt{8}}=\dfrac{6.255}{2.828}=2.212
