To which expression does 3(a + 2b) - 3a simplify? a. -6a + 6b c. 2b b. 3a + 6b d. 6b
Answers
3a + 6b - 3a
The 3a and (-3a) cancel out
Leaving you with 6b
The answer: d. 6b
Answer:
d. 6b
Step-by-step explanation:
Simplify the following:
[tex] \longrightarrow [/tex] 3(a + 2b) - 3a
3(a + 2b) = 3a + 6b:
[tex] \longrightarrow [/tex] 3a + 6b - 3a
Grouping like terms,
3a + 6b - 3a = 6b + (3a - 3a):
[tex] \longrightarrow [/tex] 6b + (3a - 3a)
3 a - 3 a = 0:

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)
Answers
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

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.
Answers
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.

Michael received $275 more from relatives than friends. He received $4275 dollars in all, how much money did he receive from relatives and how much money did he receive from friends?
Answers
Answer:
4000 thousand from relatives and 275 from friends
Answer:
Michael received $2275 ftom relatives and $2000 from friends
Step-by-step explanation:
Let r represent the amount of money from relatives
Let f represent the amount of money from friends
f+r=4275
f+275=r
Use substitution, f+(f+275)=4275
2f+275=4275
2f=4000
f=2000
Substitute 2000 in for f
2000+275=r
2275=r

5x and the length of KM is 3x +12 units. Find the
Length of JM
J
K
L
M

Answers
Answer:
[tex] JM = 60 units [/tex]
Step-by-step explanation:
Given:
[tex] JM = 9x + 6 [/tex]
[tex] JK = 5x [/tex]
[tex] KM = 3x + 12 [/tex]
[tex] JK + KM = JM [/tex] (segment addition postulate)
[tex] (5x) + (3x + 12) = (9x + 6) [/tex] (substitution)
Solve for x
[tex] 5x + 3x + 12 = 9x + 6 [/tex]
Collect like terms
[tex] 5x + 3x - 9x = -12 + 6 [/tex]
[tex] -x = -6 [/tex]
Divide both sides by -1
[tex] x = 6 [/tex]
[tex] JM = 9x + 6 [/tex]
Plug in the value of x
[tex] JM = 9(6) + 6 [/tex]
[tex] JM = 54 + 6 [/tex]
[tex] JM = 60 units [/tex]
Fruit flies, like almost all other living organisms, have built-in circadian rhythms that keep time even in the absence of external stimuli. Several genes have been shown to be involved in internal timekeeping, including per (period) and tim (timeless). Mutations in these two genes, and in other genes, disrupt timekeeping abilities. Interestingly, these genes have also been shown to be involved in other time-related behavior, such as the frequency of wingbeats in male courtship behaviors. Individuals that carry particular mutations of per and tim have been shown to copulate for longer than individuals that have neither mutation. But do these two mutations affect copulation time in similar ways? The following table summarizes some data on the duration of copulation for flies that carry either the tim mutation or the per mutation (Beaver and Giebultowicz 2004).
Mutation Mean copulation duration (min) Standard deviation of copulation duration Sample size, n
per 17.5 3.37 14
tim 19.9 2.47 17
Assume that the copulation time data are normally distributed. Do tim and per mutations lead to different mean copulation durations? Determine the absolute value of the test statistic for the appropriate test.
Answers
Answer:
The decision Rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to states that tim and per's mutations lead to different mean copulation duration.
The test statistics is [tex]z =-2.2187[/tex]
Step-by-step explanation:
From the question we are told that
The Mutation Mean copulation duration is for per [tex]\= x_1 = 17.5[/tex]
The Mutation Mean copulation duration is for tim [tex]\= x_2 = 19.9[/tex]
The Mutation Standard deviation copulation duration for is per [tex]s _1 = 3.37[/tex]
The Mutation Standard deviation copulation duration for is tim [tex]s _2 = 2.47[/tex]
The sample size for per is [tex]n_1 = 14[/tex]
The sample size for tim is [tex]n_2 = 17[/tex]
The null hypothesis is [tex]H_o : \mu_1 = \mu_2[/tex]
The alternative hypothesis is [tex]H_a : \mu_1 \ne \mu_2[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{\=x_1 - \= x_2 }{ \sqrt{\frac{s_1^2 }{n_1} + \frac{s_2^2 }{n_2} } }[/tex]
=> [tex]z = \frac{17.5 - 19.9 }{ \sqrt{\frac{3.37^2 }{14} + \frac{2.47^2 }{17} } }[/tex]
=> [tex]z =-2.2187[/tex]
From the z table the area under the normal curve to the left corresponding to -2.2187 is
[tex]P(Z < -2.2187) = 0.013254[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 * P(Z <-2.2187 )[/tex]
=> [tex]p-value = 2 * 0.013254[/tex]
=> [tex]p-value = 0.02651[/tex]
Let assume that the level of significance is [tex]\alpha = 0.05[/tex]
So
From the value obtained we see that [tex]p-value < \alpha[/tex] hence
The decision Rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to states that tim and per's mutations lead to different mean copulation duration.
