Rewrite the 4cm: 8km as a ratio in the form 1: n
Answer:
1 : 200000
Step-by-step explanation:
4 cm ⇒ 8 km
4 cm ⇒ 8 × 1000m
4cm ⇒ 8000m
4 cm ⇒ 8000 × 100 cm
4 cm ⇒ 800000cm
4 : 800000
[tex]\frac{ 4 \:\::\:\ 800000}{4}[/tex]
1 : 200000
Therefore,
1 : n

Is the trend line linear? If so, write a linear equation that represents the trend line. Show your work. I am having trouble writing the equation will someone do it for me because I don't understand.
Answer:
Our equation: y = 200x/3 + 100
Step-by-step explanation:
The trend line is linear.
y = mx + b
=> b = y-intercept = 100
=> m = slope = rise/run
=> 400/6 = 200/3
=> Slope = 200/3
Our equation: y = 200x/3 + 100

Suppose that a box contains one fair coin (Heads and Tails are equally likely) and one coin with Heads on each side. Suppose further that someone else selects one of the two coins at random, tosses it three times, and gets the outcome {Heads, Heads, Heads}. In this problem, you will answer the following question in several parts: What is the probability that the chosen coin was the fair coin
Using conditional probability, it is found that there is a 0.1 = 10% probability that the chosen coin was the fair coin.
Conditional Probability
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened. [tex]P(A \cap B)[/tex] is the probability of both A and B happening. P(A) is the probability of A happening.In this problem:
Event A: Three heads.Event B: Fair coin.The probability associated with 3 heads are:
[tex]0.5^3 = 0.125[/tex] out of 0.5(fair coin).1 out of 0.5(biased).Hence:
[tex]P(A) = 0.125 + 0.5 = 0.625[/tex]
The probability of 3 heads and the fair coin is:
[tex]P(A \cap B) = 0.5(0.125) = 0.0625[/tex]
Then, the conditional probability is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0625}{0.625} = 0.1[/tex]
0.1 = 10% probability that the chosen coin was the fair coin.

Answer:
C. (2,7)
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
In order to find which ordered pair makes the equation true, we have to understand that the format of a coordinate pair is (x, y)
Knowing that, we can plug in the numbers from each coordinate pair that correspond to the x and y values of the equation
For instance, for A (-1, 5) we would plug in 5 for x and -1 for y
Now we have -1 = 3(5) + 1
Multiply 3 and 5
-1 = 15 +1
Add
-1 = 16
The numbers on each side are not equal so this is not the answer
Now for B (10,3)
We do the same thing, plug in the numbers
3 = 3(10) + 1
Multiply
3 = 30+1
3 = 31
This choice is false as well
Option C (2, 7)
Plug in the numbers
7 = 3(2) + 1
Multiply
7 = 6+1
Add
7 = 7
Thus C is the answer as it is the same number on both sides~!

suppose another tire is rolled 100 revolutions and travels about 5027 inches what is the radius of this tire NEED THIS ANSWERED
Answer:
8 in
Step-by-step explanation:
The radius of the tire is 8.00 inches
How to determine the radius?The given parameters are:
Revolution, r = 100
Distance, d = 5027
Start by calculating the circumference of the tire using:
C = d/r
This gives
C = 5027/100
Evaluate
C = 50.27
The circumerence of a circle is:
C = 2pi r
This gives
2pi r = 50.27
Make r th subject
r = 50.27/2pi
Evaluate the quotient
r = 8.00
Hence, the radius of the tire is 8.00 inches

uppose a normal distribution has a mean of 16 and a standard deviation of 4. A value of 26 is how many standard deviations away from the mean
Answer:
2.5 s. d.
Step-by-step explanation:
Use the formula for calculating z scores:
26 - 16
z = ------------- = 10/4 = 2.5

Here the value 26 is 2.5 standard deviations above the mean (16).
The vertices of a feasible region are (14, 2), (0, 9), (6, 8), and (10, 3). What is the maximum value of the objective function P if P = 180x 250y?.
The maximum value of the objective function is 3080
The vertices of a feasible region are given as
(14, 2), (0, 9), (6, 8), (10, 3)
The objective function is given as:
[tex]\mathbf{P = 180x + 250y}[/tex]
Substitute the ordered pairs in the objective function
Point (14,2)
[tex]\mathbf{P = 180 \times 14 + 250 \times 2}[/tex]
[tex]\mathbf{P = 3020}[/tex]
Point (0,9)
[tex]\mathbf{P = 180 \times 0 + 250 \times 9}[/tex]
[tex]\mathbf{P = 2250}[/tex]
Point (6,8)
[tex]\mathbf{P = 180 \times 6 + 250 \times 8}[/tex]
[tex]\mathbf{P = 3080}[/tex]
Lastly, we have point (10,3)
[tex]\mathbf{P = 180 \times 10 + 250 \times 3}[/tex]
[tex]\mathbf{P = 2550}[/tex]
The maximum value of P is calculated to be 3080.

AC = 24
Step-by-step explanation:
DE is the midline of the triangle, parallel to AC. It is half the length of AC, so ...
2·DE = AC
2(2x -14) = 3x -15
4x -28 = 3x -15 . . . . . eliminate parentheses
x = 13 . . . . . . . . . . . . . add 28-3x to both sides
AC = 3x -15 = 3(13) -15
AC = 24

DE = 2(13) -14 = 12, half the length of AC.
