Answer:
v=-5
Step-by-step explanation:
39=4 -7v
39-4= (4-4) -7v
35=-7v
35/-7= -7v/-7
-5=v
Solve the equation 7 minus 2X equals 19
Answer: x=-6
Step-by-step explanation:
Answer:
x=-6
Step-by-step explanation:
Put it in an equation,
7-2x=19
Solve for x
Subtract 9 on both sides
-2x=12
Divide -2 on both sides
x=-6
what is the constant proportionality of this graph
Answer:
0 to 10
Step-by-step explanation:
The table shows the height of water in feet at different times. The water rises and falls in a cyclical pattern.
A 2-column table with 5 rows. Column 1 is labeled x with entries 12 a m, 3 a m, 6 a m, 9 a m, 12 p m. Column 2 is labeled y with entries 6, 10, 6, 2, 6.
Which equation models the data in the table?
y = 6 sine (StartFraction pi Over 6 EndFraction x) + 2
y = 6 sine (StartFraction pi Over 6 EndFraction x) + 4
y = 4 sine (StartFraction pi Over 6 EndFraction x) + 6
y = 4 sine (StartFraction pi Over 6 EndFraction x) + 10
Answer:
c
Step-by-step explanation:
Modeling the data in the table is done via the equation y = 4 sine (pi/6x) + 6.
What is a cyclic pattern?Over a period of years, a cyclical pattern recurs with considerable regularity. Cyclical patterns are distinct from seasonal patterns in that they last across a number of years as opposed to only one year for seasonal trends.
Given, The table shows the height of water in feet at different times. The water rises and falls in a cyclical pattern.
Table:
12 AM 6
3 AM 10
6 AM 6
9 AM 2
12 PM 6
from the general formula of wave
y = A sin(bx + c)
Substituting values in the equation from the graph attached below:
6 = A sin(0*b + c)......(1)
10 = A sin3b + c...(2)
6 = A sin6b + c......(3)
2 = A sin9b +c........(4)
Since -c/b is a phase shift of the graph
Thus
-c/b = 6
c = -6b
from equations 2 and 1
2* 6 = Asin(-3b) = -Asin3b
2 * 6 = Asin(-6b) = -Asin6b
2* 6/6 =sin6b/sin3b
1 = Cos3b
Thus b = π/6
from substitution in equations 3
6 = A sin6b + c
=> 6 = Asin 6* pi/6 + c
=> c = 6

10 = A sin3b + c
A = 4
therefore, The equation that models data in the table is y = 4 sine (pi/6x) + 6.

What is the answer for 2m+5=5m-35-3m
Answer:
No solution.
Step-by-step explanation:
The m's on both sides simplify to cancel out, leaving you with 5=-35, a false statement.
Answer:
No Solution
Step-by-step explanation:
We leave 2m +5 as it is because we can't combine any like terms on the left side. Over on the right side, we can combine 5m with -3m to get 2m -35. Now we have 2m+5 = 2m-35. We can subtract 2m on the left or right side which then gets us 5=-35 which is No solution. Hope this helps!

-6(1/4x-2/3x+5/6x) simplified .
Answer:
[tex]-2\frac{-1}{2}[/tex]
Step-by-step explanation:
To distribute the -6, multiply every numerator by -6, this gets you
-6/4+12/3-30/6
To put these together, they all need to have a common denominator. We can make all of the denomiators 12 by multiplying the numerator by whatever we multiply the denominators by to get 12.
-18/12+48/12-60/12
This gets you -30/12
To make this a proper fraction, divide -30 by 12 and put the whole number to the left of the fraction (-2), making a mixed number. The remainder stays a fraction which is -6/12. This reduces down to -1/2. Put -2 and -1/2 together to get [tex]-2\frac{-1}{2}[/tex]

is 1.36 a rational number or irrational number
Answer:
No an irrational number
Step-by-step explanation:
An irrational number is a number that cannot be expressed as a fraction of two integers . -1.36 can be expresed as -136/100
Answer:
Rational!
Step-by-step explanation:
Any number that can be written in fraction form is a rational number. This includes integers, terminating decimals, and repeating decimals as well as fractions. So, any terminating decimal is a rational number. Any decimal number that is repeating can be written in the form a/b with b not equal to zero so it is a rational number.
I hope this helps you understand what a rational number is! Have a wonderful day!

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.

B (same slope, lower starting point)
Step-by-step explanation:
The slope on this graph is 5, and the slope of y=5x+5 is 5, so the slopes are the same.
This graph has a y-intercept of -6, which is lower than y=5x+5's intercept of 5, so it starts lower, so B.

Answer:

Step-by-step explanation:
i just got it right
The parent absolute value function will be contract by factor 0.8.
What is Dilation?Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original.
We have,
f(x) = 0.8 |x|
We know the 0.8 represent the scale factor which leads to dilation.
As, 0.8 < 1 then it means that the figure is going to be contract or smaller than original figure.
Thus, the Function will be contract by factor 0.8

The Law of Large Numbers states that as an experiment is repeated, the relative frequency of an event tends toward the real probability.
a. if the probability of a specific observed event is very small, it is unlikely that the assumption about the probability is correct.
b. the probability of obtaining a favorable outcome increases as the number of trials increases.
c. the sampling distribution of the sample mean will be approximately normally distributed as long as the sample size is sufficiently large.
d. the probability that an event will occur is derived from one's increasing knowledge of relevant circumstances.
Answer:
the probability of obtaining a favorable outcome increases as the number of trials increases
Step-by-step explanation:
The law of large numbers occupies an important place in probability statistics especially as it regards the outcome of experiments.
A simple statement of this law is that; when an experiment is independently repeated a large number of times, the average result, that is obtained is close to the expected value.
Hence, the probability of obtaining a favorable outcome increases as the number of trials increases.
