what is the perimeter of a quadrilateral with vertices at (1,5), (6,5), (1,11), and (6,11)? enter the answer in the Ⴆσx
Answers
Answer:
perimeter = 25.62 units
Step-by-step explanation:
Let the quadrilateral be ABCD
A = (1, 5), B = (6, 5), C= (1, 11) , D = (6, 11)
To find the perimeter we need to add the lengths of sides AB , BC, CD, and AD.
Lets find the length of all sides using distance formula;
[tex]distance = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
[tex]AB = \sqrt{(1-6)^2+(5-5)^2} = \sqrt{25} = 5units\\\\BC= \sqrt{(6-1)^2+(5-11)^2} = \sqrt{25+36} =\sqrt{61} units\\\\CD=\sqrt{(1-6)^2 + (11-11)^2} = \sqrt{25} = 5units\\\\AD = \sqrt{(1-6)^2+(5-11)^2} = \sqrt{25+36} = \sqrt{61}units[/tex]
Perimeter = AB + BC + CD + AD
[tex]=10 + 2\sqrt{61} units[/tex] = 25.62 units

The probability of tails of a weighted coin is 0.58. The number of tails is noted each of the 25 times the coin is tossed. If this procedure is repeated 150 times, what type of distribution is simulated
Answers
Answer:
It is a sampling distribution of the sample proportion for which n = 150 and p = 0.58
Step-by-step explanation:
Given -
Probability of tails of a weighted coin = 0.58
Number of tail is noted each 25 times
Repetition of procedure = 150 times
mean = p = 0.58
SD = Sqrt {p(1-p)/n}
Substituting the given values, we get -
SD = Sqrt {0.58(1 – 0.58)/150}
= 0.04029
It is a sampling distribution of the sample proportion for which n = 150 and p = 0.58
Answer:
The options are not given so these are the options:
- A binomial distribution with n = 25 and p = 0.58
- A binomial distribution with n = 2 and p = 0.58
- A sampling distribution of the sample proportion with n = 25 and p = 0.58
- A sampling distribution of the sample proportion with n = 150 and p = 0.58
- There is not enough information to determine the distribution.
Step-by-step explanation:
The answer is - A binomial distribution with n = 25 and p = 0.58.

Final volume, V2 = 8.57 liters
Step-by-step explanation:
Given the following data;
Initial volume, V1 = 7.7 liters
Initial pressure, P1 = 6.9 atm
Final pressure, P2 = 6.2 atm
To find the new volume V2, we would use Boyles' law.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
[tex] PV = K[/tex]
[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]
Substituting into the equation, we have;
[tex] 6.9 * 7.7 = 6.2*V_{2} [/tex]
[tex] 53.13 = 6.2V_{2} [/tex]
[tex] V_{2} = \frac {53.13}{6.2}[/tex]
[tex] V_{2} = 8.57 [/tex]
Final volume, V2 = 8.57 liters
Therefore, the new volume is 8.57 liters.

26 divided by a number r
Answers
Answer:
26 ÷ r
Step-by-step explanation:
Is your expression.
Using the keywords divide you can identify the expression, its showing you divide 26 by r, r in this case is your unknown value(variable). This expression is showing what you divide. You can also consider this as 26/r
Answer:
26/r
Step-by-step explanation:
So when they say a number they are meaning r.
Now lets break this into two simpler pieces.
When they say dividing by r they mean over r, or:
[tex]\frac{}{r}[/tex]
They say 26 is what is being divided by, which means 26 over, or:
[tex]\frac{26}{}[/tex]
Now we just need to combine these two pieces together:
[tex]\frac{26}{r}[/tex]

Determine the length of CD.
Question 13 options:
A)
10.77 units
B)
3.74 units
C)
6.32 units
D)
9.17 units
Answers
Answer:
The answer is 6.32
Step-by-step explanation:
According to the Altitude Geometric Mean Theorem, the length of the altitude of a triangle is the geometric mean of the lengths of the 2 segments is divides the hypotenuse into.
CD= Altitude
CD^2= 4 times 10
or
CD= The square root of 4 times 10
Square root of 4 times 10 is 6.3245553203
Two figures are known as similar figures if there the corresponding angles are equal and the corresponding sider is in ratio. The length of CD is 6.32 units. The correct option is C.
What are Similar figures?Two figures are known as similar figures if there the corresponding angles are equal and the corresponding sider is in ratio. It is denoted by the symbol "~".
In ΔBDC and ΔABC, the two angles are given,
∠D = ∠C = 90°
∠B = ∠B {Common}
Therefore, the two triangles are similar triangles, thus, the ratio of the sides can be written as,
CB / AB = CD / AC = DB / CB
Now, the ratio can be solved as,
CB / AB = DB / CB
CB / 14 = 10 / CB
CB² = 14 × 10
CB = √140
Further, in triangle ABC using the Pythagorean theorem, we can write,
AB² = CB² + AC²
14² = (√140)² + AC²
196 - 140 = AC²
AC = √56
Again, using the ratio of the similar triangle, we can write,
CD / AC = DB / CB
CD / √56 = 10 / √140
CD = (√56 × 10)/√140
CD = 6.32 units
Hence, the length of CD is 6.32 units.

Answers
Answer:
A. 16 × 10¯⁷
B. 2 × 10⁷
Step-by-step explanation:
A. 8×10¯³ × 2×10¯⁴
Recall:
Mᵃ × Mᵇ = Mᵃ⁺ᵇ
Thus,
(8×10¯³) × (2×10¯⁴) = (8×2) × 10¯³ ⁺ ¯⁴
= 16 × 10¯³¯⁴
= 16 × 10¯⁷
Therefore,
(8×10¯³) × (2×10¯⁴) = 16 × 10¯⁷
B. (6×10²) ÷ (3×10¯⁵)
Recall:
Mᵃ ÷ Mᵇ = Mᵃ¯ᵇ
Thus,
(6×10²) ÷ (3×10¯⁵) = (6/3) × 10² ¯ ¯⁵
= 2 × 10²⁺⁵
= 2 × 10⁷
Therefore,
(6×10²) ÷ (3×10¯⁵) = 2 × 10⁷
