Answer:
16
Step-by-step explanation:
Basically,
1st step: Look at the key words 5%, 60%, total cost, 15%.
Next, divide 60/15 (=4)
Then, divide 60/5 (=12)
Now, you add up 4 + 12 (=16)
Then, you lastly subtract 60 - 16 (=44)
And, they were asking for the total cost of the tax and tip (16)
So, your answer is 16!
Hope I could help! :D
Let me know if you have any problems understanding, I will be very glad to help you.

Find abs equation of the line with the given slope that passes through the given point. Write the equation in the from Ax+By=C M=7, (3,3)
Answer: The equation of the line in slope-intercept form will be
y = (7/4)x + b
Since the line passes through the point (8,-2), plug in the values of the point into the equation to find b.
-2 = (7/4)(8) + b
-2 = 14 + b
-16 = b
The equation of the line is
y = (7/4)x - 16
In standard form,
-(7/4)x + y = -16
Multiply both sides of equation by -4.
7x - 4y = -64

Step 1:
y = mx + b Slope Intercept Form
Step 2:
y = x - 1 Equation/Given
Step 3:
Slope = 1
Answer:
A: Slope = Positive
Since there are no symbols or numbers in front of the x it means that the slope is x and the slope is positive.

PLEASE HELP IT'S DUE TOMORROW!!
Answer: I am also learning the same thing but this is better than nothing.
f(x,y)→(x-3,-y-2)
Step-by-step explanation:
So basically the base form is f(x,y) that is why I added it there. Then the transformation reflects the shape over the x-axis which changes it from f(x,y)→(x,-y). If you take point A, for example, it is (0,1). When reflected, as the formula shows, it becomes (0,-1) and that is where the negative sign before the y comes from. Then we translate point A left 3 and down 2. That makes the point become (-3,-3) which is where A prime is. That also changes the formula to f(x,y)→(x-3,-y-2). This should work for the ENTIRE shape and ALL THE POINTS. -DooDOoHeaad
State weather the following can be expressed as a ratio 12g and 45kg
Answer:
The anwser is always Jesus
Step-by-step explanation:
Also there is no following
The ratio of 12gm and 45 kg in simplest form is 3750 : 1.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, Are two weights in different measurement forms, To write them as a ratio we have to make their scale of measurement equal.
We know 1kg is equal to 1000 grams.
Therefore, 45 kg is equal to 45000 grams.
So, The ratio of 12gm and 45 kg is 45000 : 12.
22500 : 6.
11250 : 3.
3750 : 1.

A law was established, in which it considers that a driver who has more than 0.8 grams of alcohol per liter of blood, is in a state of drunkenness. It is estimated that the risk that a person has of suffering an accident when driving a vehicle under the influence of alcohol is given by the expression [tex]R(x) = 6 * e^{kx}[/tex] , where R(x) is the risk expressed as probability, X is the concentration of alcohol in the blood and K a constant:
A) Calculate the value of the constant K knowing that the concentration of 0.04 g / L of alcohol in the blood (x = 0.04) corresponds to an accident risk of 10% (R = 10)
B) A person who, according to the Law, drives while intoxicated, that is to say 0.8 g / L in blood, what are the risks of suffering an accident?
C) If a driver is under the influence of alcohol, that is 0.3 g / L, what is the risk of having an accident?

A) k = 18.75B) R(0.8) = 161419C) R(0.3) = 275Step-by-step explanation:
Given expression

x = 0.04R = 10Solving for k
10 = 6*e^(0.04k)e^(0.04k) = 10/6ln (e^0.04k) = ln (1.6666)0.04k = 0.51k = 0.51/0.04k = 12.75B) Given
x = 0.8R= ?The value of R(0.8) is:

R(0.3) =6*e^(0.3*12.75) = 6*e^(3.825) =275 roundedSuppose that you are interested in estimating the average impact a job training program has on wages. After controlling for observed factors that influence wages, participation in the training program, you find that the coefficient for the training is 0.55 and the standard error is 1.06. Thus, we can infer that the training program has a positive and statistically significant impact on wages at a 95% confidence level.
a) true
b) false
Answer:
False
Step-by-step explanation:
From the question we are told that
The coefficient for the training is [tex]r = 0.55[/tex]
The standard error is [tex]SE = 1.06[/tex]
The confidence level is 95%
Generally the level of significant is mathematically represented as
[tex]\alpha =( 100 -95)\%[/tex]
=> [tex]\alpha = 0.05 [/tex]
Generally the critical value of [tex]\alpha = 0.05 [/tex] obtained from the normal distribution table is [tex]Z_{0.05} = 1.645[/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{r }{SE}[/tex]
=> [tex]t = \frac{0.55}{1.06}[/tex]
=> [tex]t = 0.5189 [/tex]
Generally given that the [tex]t < Z_{\alpha }[/tex]
Hence there is no sufficient evidence to conclude that the program has a positive and statistically significant impact on wages at a 95% confidence level.
So the answer is False
As men age, their testosterone levels gradually decrease. This may cause a reduction in lean body mass, an increase in fat, and other undesirable changes. Do testosterone supplements reverse some of these effects? A study in the Netherlands assigned 237 men aged 60 to 80 with low or low-normal testosterone levels to either a testosterone supplement or a placebo. The report in the Journal of the American Medical Association described the study as a "double-blind, randomized, placebo-controlled trial." Explain each of these terms to someone who knows no statistics.1) Explain the term "double-blind" study?2) True or False: :"Randomized means that the subjects were selected randomly from the population of men aged 60 to 80 with low or low-normal testosterone levels."3) Explain the meaning of the term "placebo-controlled" trial?
Answer:
Answered below.
Step-by-step explanation:
1) A double - blind study is simply an experiment in which neither the participants nor the people who carry out the experiment know who is receiving any particular treatment. This method is usually used in order to prevent a biased view in research results.
2) True because randomized simply means that subjects were assigned to the group randomly.
3) Placebo - controlled trial simply means that there was a control group that received only a placebo treatment which is mainly designed not to have real effect.

Which of the following is the inverse of f(x)=3-x/5
Answer:
f^-1(x) = 3 - 5x, second option
Step-by-step explanation:
To determine the inverse simply interchange the variables and solve for y;
f(x) = 3 - x / 5 -> Interchange the variables
x = 3 - y/5 -> Multiply either side by 5
5x = 3 - y -> Subtract three from either side
- y = 5x - 3 -> Divide either side by - 1
y = - 5x + 3
Your solution is f^-1(x) = 3 - 5x

Recall the following property of exponents:
[tex]a^b\cdot a^c=a^{b+c}[/tex]
[tex]\implies 216^{-3k}\cdot 216^{-2k}=216^{-3k-2k}=216^{-5k}[/tex]
Now, notice that 6² = 36 and 6³ = 216, which means that
[tex]216^{-5k}=36^{2k-1} \iff (6^3)^{-5k}=(6^2)^{2k-1}[/tex]
Recall another property of (real) exponents:
[tex](a^b)^c=a^{bc}[/tex]
[tex]\implies(6^3)^{-5k}=6^{3(-5k)}=6^{-15k}\text{ and }(6^2)^{2k-1}=6^{2(2k-1)}=6^{4k-2}[/tex]
So we have
[tex]216^{-5k}=36^{2k-1} \iff 6^{-15k}=6^{4k-2}[/tex]
Since both sides are equal powers of 6, that must mean that the exponents must be equal, so
[tex]-15k=4k-2[/tex]
Solve for k :
[tex]-15k-4k=(4k-4k)-2[/tex]
[tex]-19k=-2[/tex]
[tex]k=\dfrac{-2}{-19}=\boxed{\dfrac2{19}}[/tex]

Answer:
f(-6) = 40
Step-by-step explanation:
Step 1: Define
f(x) = 5(2 - x)
f(-6) is x = -6
Step 2: Substitute and Evaluate
f(-6) = 5(2 - (-6))
f(-6) = 5(2 + 6)
f(-6) = 5(8)
