These two lines are graphs of non-proportional relationships. What makes them non-proportional?
Answer:
These two lines are graphs of non-proportional relationships because
" They do not go through the origin " ⇒ B
Step-by-step explanation:
If two quantities x and y are proportional, then
The relationship between them is represented by the equation y = k xk is the constant of proportionalityThe relationship represents graphically by a line must pass through the origin pointFrom the given graph
∵ The first line intersects the y-axis at point (0, 3)
∴ The line does not pass through the origin
∴ The line is a graph of the non-proportional relationship
∵ The second line intersects the y-axis at point (0, -2)
∴ The line does not pass through the origin
∴ The line is a graph of the non-proportional relationship
These two lines are graphs of non-proportional relationships because
" They do not go through the origin "
Step-by-step explanation:
These Two Graphs Are non proportional because C)They do no go through the graphs
Suppose you scored 95 on a measure where the mean was 110 and the standard deviation was 15. Assuming a normal distribution, what percentage of scores should fall between your score and the mean?
Answer:
34% of scores should fall between your score and the mean.
Step-by-step explanation:
Let X denote the score.
It is provided that X follows a normal distribution with mean 110 and standard deviation 15.
A students score, x = 95.
Compute the probability of scores that should fall between the student's score and the mean as follows:
[tex]P(95<X<110)=P(\frac{95-110}{15}<\frac{X-\mu}{\sigma}<\frac{110-110}{15})[/tex]
[tex]=P(-1<Z<0)\\\\=P(Z<0)-P(Z<-1)\\\\=0.50-0.15866\\\\=0.34134\\\\\approx 0.34[/tex]
Thus, 34% of scores should fall between your score and the mean.

Equation:
5a² - 2a - 10 for a = -6.
Evaluate by plugging in -6 for a:
5(-6)² - 2(-6) - 10 =
5(36) - (-12) - 10 =
180 + 12 - 10 = 182.

What is the difference between a co-payment and co-insurance?
a. Co-payment refers to two spouses paying for the same coverage, and co-insurance refers to
two spouses receiving the same benefits.
b. A co-payment is a flat fee for each service, and co-insurance is based on a percentage of the
costs incurred.
C. Co-payment is when a group of individuals work to cover each other's medical expenses, and
co-insurance is when an individual has multiple insurance policies from different companies.
d. A co-payment is when an employer helps an employee pay for insurance premiums, and co-
insurance is when an employer helps an employee find better insurance than they could alone.
Answer:
b. A co-payment is a flat fee for each service, and co-insurance is based on a percentage of the costs incurred.
Step-by-step explanation:
A co-payment can be defined as a relatively small fixed amount of money that is required to be paid by a patient (insured) to a service provider such as a health insurer (health maintenance organization-HMO) as medical expenses before receiving any other service. Some examples of co-payment are the payment of $15 for a visiting gynecologist, £5 for prescribed drugs, ¥20 for x-ray etc.
On the other hand, co-insurance can be defined as the amount of money a patient (insured) is required to pay for a claim or covered charge after a deductible have been satisfied and it is typically expressed as a percentage of the costs incurred. It is usually split between the policyholder and the insurer on a 20% to 80% basis.
Hence, the difference between a co-payment and co-insurance is that, co-payment is a flat fee for each service, and co-insurance is based on a percentage of the costs incurred.

Help ASAP pls What is the y intercept of the linear equation shown on the graph
A. (0,-70)
B. (0,-50)
C. (0,1/2)
D. (0,100)
Answer:
(0, -50)
Step-by-step explanation:
pick any 2 points such as (100,0) and (120,10)
to get from point (100.0) to point (120,10) you had to rise 10 and run 20
so the slope m =rise 10/run20= 1/2
the equation of the line is (y-y1)=m(x-x1)
(y-0)=(1/2)(x-100) for the slope m=1/2 and point on the line (100,0)
y=( x/2)-50 if you distribute
compare this with the equation
y=mx+b wher m=slope and bb is y-intercept
so the y-intercept is -50

B. The slope ls -2, and the y-intercept is 12.
C. The slope is 2, and the y-intercept is 6.
D. The slope is 2, and the y-intercept is 12.
Answer:
A
Step-by-step explanation:
Answer:
Step-by-step explanation:
Use two points and find slope initially so,
(-3,18) (0,12)
18-12=6 , -3-0= -3
so the slope is 6/-3 = -2 so by this answer is either a or b .
further apply y =mx + c as it linear to find c
y= -2x + c
0 = -2x6 + c
c = 12
so slope is -2 , c is 12

The amount of gasoline G sold each month to customers at Bob's Exxon station in downtown Navasota is a random variable. This random variable G can be described as having a normal distribution with mean 2500 gallons and a standard deviation of 250 gallons (and there is no seasonal variation in sales). Exxon will give Bob an all-expense paid trip to College Station, including a free dinner at Burger King, if his station pumps more than 3000 gallons in any one month.
Required:
What is the probability that Bob will win that wonderful trip on the basis of his gasoline sales this month?
Answer:
The probability is [tex]0.0228[/tex]
Step-by-step explanation:
Let's start by defining the random variable [tex]G[/tex] as :
[tex]G:[/tex] '' The amount of gasoline sold each month to customers at Bob's Exxon station in downtown Navasota ''
Therefore, if [tex]X[/tex] is a continuous random variable that has a normal distribution, we write [tex]X[/tex] ~ [tex]N[/tex] ( μ , σ )
Where ''μ'' is the mean and ''σ'' is the standard deviation.
For the random variable [tex]G[/tex] we write :
[tex]G[/tex] ~ [tex]N(2500,250)[/tex]
We need to find [tex]P(G>3000)[/tex]
In order to calculate this, we are going to standardize the variable. This means, finding the equivalent probability in a normal random variable
[tex]Z[/tex] ~ [tex]N(0,1)[/tex]
We perform this because the random variable [tex]Z[/tex] ~ [tex]N(0,1)[/tex] is tabulated in any book or either you can find the table on Internet.
To standardize the variable we need to subtract the mean and then divide by the standard deviation ⇒
[tex]P(G>3000)[/tex] ⇒ P[ (G - μ) / σ > [tex]\frac{3000-2500}{250}[/tex] ] ⇒ [tex]P(Z>2)[/tex]
Because (G - μ) / σ ~ [tex]Z[/tex]
Finally, [tex]P(G>3000)=P(Z>2)[/tex] ⇒ [tex]P(Z>2)=1-P(Z\leq 2)[/tex] = 1 - Φ(2)
Where '' Ф(x) = [tex]P(X\leq x)[/tex] '' represents the cumulative function of [tex]Z[/tex]
Looking for Φ(2) in any table,
[tex]P(G>3000)=P(Z>2)=1-P(Z\leq 2)=1-0.9772=0.0228[/tex] ≅ %2.28
We found out that the probability is [tex]0.0228[/tex]
