Answer:
Option 2
Step-by-step explanation:
Since both triangles are similar, that means that the larger triangle's sides are greater than the smaller triangle's sides by a factor. We can see that 10 corresponds to x, so in the proportion 10 and x must be on the same side. That rules out option one and three. Now, we see that 7 corresponds to 14 and 6 corresponds with 12, so the other side must have 6 and 12 on the same side or 7 and 14 on the same side. We see that the only option that satisfies this criteria is Option 2.
Answer:
Option 2 - [tex]\frac{10}{x} =\frac{7}{14}[/tex]
Step-by-step explanation:
So, lets just look at the two traingles, find the difference, then see if the graphs will give us the same difference.
So lets see.
One side of triangle ABC is 6. The same side of triangle DEF is 12.
Another side of triangle ABC is 7. THe same side of trinalge DEF is 14.
The final side of trinalge ABC is 10. The same side of triangle DEF is x.
We only need to compare a single side of these to find the difference:
12/6=2
14/7=2
This is very simple.
However, lets shift this into what they wrote.
So we know that the difference between each side is 2.
ALL sides are like this.
We know that both 12/6 and 14/7 equal the same thing, so tecnically, they are equal:
12/6=14/7
This is the same with 10/x as well.
So:
10/x=14/7
10/x=12/6
So we know that the difference from ABC to DEF is 2. But the difference from DEF to ABC is the opposite, 1/2.
Knowing this:
x/10=6/12 is the same thing as 10/x=12/6. And x/10=7/14 is the same thing as 10/x=14/7
So our answers can also be:
x/10=7/14
x/10=6/12
This looks like option 2.
Hope this helps!

Suppose g(m) varies inversely with M and g (m) = 3.5 when m = 10.
What is the value of m when g (m) = 5 ?
Answers
Answer:
m =7.
Step-by-step explanation:
Let the constant number = k.
g(m) = k/m,
3.5 = k/10,
k = 35.
Thus, when g(m) = 5 = 35/m, m = 7.

The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between and minutes. Find the probability that a randomly selected passenger has a waiting time minutes.
Answers
Answer:
Incomplete question, but I gave you a guide on the uniform distribution, and thus you just have to replace the values in these equations to find the desired probabilities.
Step-by-step explanation:
Uniform probability distribution:
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
[tex]P(X < x) = \frac{a - x}{b - a}[/tex]
The probability of finding a value between c and d is:
[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]
The probability of finding a value above x is:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
Between a and b minutes.
Here you get a and b for the uniform distribution.
Find the probability that a randomly selected passenger has a waiting time minutes.
Here you will have the value of x.

Answers
Answer:
[tex]A(x) = 12000(1.04)^x[/tex]
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
$12000 cash
This means that [tex]P = 12000[/tex]
Compounded at 4% interest annually.
This means that [tex]r = 0.04, n = 1[/tex]
What equation will calculate the value in x years?
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(x) = P(1 + \frac{r}{n})^{nx}[/tex]
[tex]A(x) = 12000(1 + 0.04)^x[/tex]
[tex]A(x) = 12000(1.04)^x[/tex]
A ladder 18 ft long rests against a vertical wall. Let θ be the angle between the top of the ladder and the wall and let x be the distance from the bottom of the ladder to the wall. If the bottom of the ladder slides away from the wall, how fast does x change with respect to θ when θ = π 3 ?

Answer: [tex]9\ ft/rad[/tex]
Step-by-step explanation:
Given
Length of the ladder is [tex]l=18\ ft[/tex]
Angle between the wall and the ladder is [tex]\theta[/tex]
from the figure, we can write
[tex]\Rightarrow \sin \theta=\dfrac{x}{18}\\\\\Rightarrow x=18\sin \theta[/tex]
Differentiate the above equation w.r.t [tex]\theta[/tex]
[tex]\Rightarrow \dfrac{dx}{d\theta}=18\cos \theta\\\\\text{at }\theta=\dfrac{\pi }{3}\\\\\Rightarrow \dfrac{dx}{d\theta}=18\cos(\dfrac{\pi}{3})\\\\\Rightarrow \dfrac{dx}{d\theta}=18\times 0.5\\\\\Rightarrow \dfrac{dx}{d\theta}=9\ ft/rad[/tex]

1. For each of 200 randomly selected cities, Gary recorded the number of churches
in the city (x) and the number of homicides in the past decade (y). He calculated
the linear correlation coefficient and was surprised to find a strong positive linear
correlation for the two variables. Does this suggest that building new churches
causes an increase in the number of homicides? Why do you think that a strong
positive linear correlation coefficient was obtained? Explain your answer with
reference to the term lurking variable.
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
When certain variables are examined, there seems to be a sort of spurious relatuoshipnornassocuation between the two variables, this is evident in the relationship between churches and the number of homicide, when a strong positive correlation is observed between number of churches and number of homicides, this relationship is most likely to be due to the effect of a lurking or third variable which creeped into our analysis, a factor which has a posithe correlation on both number of churches and homicide level, Number of homicide and number of churches could have been correlated by the lncreasing population which may lead to overcrowding and competition Hence increasing rate of homicide, similarly, with high rise in population, the growth of church to accommodate the populees will also creep in.

Answer:
5.792
Step-by-step explanation:
To round to the nearest thousandth, look at the ten thousandths place.
If the number is greater than 5, we will round up. If it is 5 or less, we will keep the thousandths place the same.
There is a 6 in the ten thousandths place, so we will round up the thousandths place.
So, the rounded number will be 5.792

-2 (8p+2) -3(2-7p)=2(4+2p)
Answers
Answer:
p = 18
Step-by-step explanation:
Let's solve your equation step-by-step.
−2(8p+2)−3(2−7p)=2(4+2p)
Step 1: Simplify both sides of the equation.
−2(8p+2)−3(2−7p)=2(4+2p)
(−2)(8p)+(−2)(2)+(−3)(2)+(−3)(−7p)=(2)(4)+(2)(2p)(Distribute)
−16p+−4+−6+21p=8+4p
(−16p+21p)+(−4+−6)=4p+8(Combine Like Terms)
5p+−10=4p+8
5p−10=4p+8
Step 2: Subtract 4p from both sides.
5p−10−4p=4p+8−4p
p−10=8
Step 3: Add 10 to both sides.
p−10+10=8+10
p=18
Therefore, the final answer is 18, I hope this helps :D

Answer: 169'

Since the expression for ordering brushes for an art class is given as 5c - 1, where c is the class limit.
Therefore, when the class limit is 34, the expression evaluated will then be:
