90 men and 60 women were asked if they had watched the latest 'Expendables' movie.

3/10 of the women said Yes.
What percentage of the men said No?
Show your work
PLEASE HELP DUE TODAY THANK YOU SO MUCH.
.
Answer:
63 men said no.
Step-by-step explanation
3/5 * 2/2 = 6/10, 6/10 - 3/10 (women) = 3/10 meaning 7/10 men said no. 90*1.7 = 153, 153-90=63
Answer:
30%. Remember the question is what percentage?
Step-by-step explanation:
Given Informations:
Men = 90
Women = 60
Total number (men + women) = 150. ...... (1)
For Yes Members,
3/5 of the people said YES.
3/5 of 150 = 90 ....... (2)
This means that out of 150, 90 people said YES.
However, we dont know what ratio are men or women all we can deduce is that 90 said YES.
From the question, 3/10 are women that said YES.
Meaning 3/10 of 90 are women = 27. .. (3)
27 women said YES therefore
90 -27 = 63 Men said YES.
FOR NO Members,
If 90 out of 150 said yes, then 60 said NO.
However, we dont know the ratio of Men and Women that said NO. What we can do is to solve it from the known to the unknown.
For Men,
The total number is 90.
63 said YES, therefore (90 - 63 ) definitely said NO.
= 27 Men said NO (4)
For Women,
The total number of women is 60
27 said YES, Therefore (60 - 27) said NO
= 33 women said NO. ( 5)
The question is what percentage of Men said NO?
Percentage =
number of men that said NO / The total number of Men * 100
= 27/90 * 100
=30%
To Prove the Answer
If you agree with Eq 2, which says 90 people said yes. Therefore, (150 -90) = 60 said NO.
Remeber the 60 is inclusive of Men and Women.
Let's see, if we will get 60 when we add the number of men and women we got that said NO.
Add the value in Eq 4 + Eq 5.
27 + 33 = 60.

The concept of determining which reactant is limiting and which is in excess is akin to determining the number of sandwiches that can be made from a set number of ingredients. Assuming that a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, determine the number of whole cheese sandwiches that can be prepared from 44 slices of bread and 69 slices of cheese. number of sandwiches: 22 Which of the two ingredients limits the number of sandwiches that can be made
Answer:
SLICE OF BREADStep-by-step explanation:
If a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, in order to determine the number of whole cheese sandwiches that can be prepared from 44 slices of bread and 69 slices of cheese, we will use the equality postulate as shown;
1 cheese sandwich = 2 slices of bread
x cheese sandwiches = 44 slices of bread
cross multiply
2 * x = 1 * 44
2x = 44
divide both sides by 2
2x/2 = 44/2
x = 22
Similarly;
1 cheese sandwich = 3 slices of cheese
y cheese sandwiches = 69 slices of cheese
cross multiply
3 * y = 1 * 69
3y = 69
divide both sides by 3
3y/3 = 69/3
3y = 23
Since both values of x and y are greater than or equal to 22 hence 22 sandwiches can be prepared from 44 slices of bread and 69 slices of cheese.
Since the amount of cheese sandwiches made from slices of bread (22) is not up to that made from slices of cheese (i.e 23), hence the ingredient that limits the number of sandwiches that can be made is the slice of bread
write an equation to solve for x 3x + 21 6x-60 will mark brainiest
Answer:
3x + 21 = 6x - 60Step-by-step explanation:
parallel angles are equal
3x + 21 = 6x - 60
combine similar terms:
3x - 6x = -60 - 21
-3x = -81
x = 81/3
x = 27
now, plugin the value of x=27 back into the equation to get the angle:
= 3x + 21
= 3(27) + 21
= 102
= 6x - 60
= 6(27) - 60
= 102
as you noticed, both values are equal 102 = 102 because its a parallel angles
so the equation is 3x + 21 = 6x - 60

What are the two question that you want to ask to clarify the process of translating real life situation to rational function
Answer and Step-by-step explanation:
The rational function is the function that can be written in terms of ratio that contains two polynomial functions in which the denominator is not equivalent to zero
Now the two questions that should be asked which are as follows:
1. Translate real life to rational functions.
2. Process for translate to real life to rational functions
These two questions should be asked
The two question that I want to ask to clarify the process of translating real life situation to rational function are
How can I tell if a function is rational or not?How do rational functions apply in real life situationFor better understanding, lets explain what rational function means.
Rational function is simply known to be the function of the form f(x)= p(x)/q(x) where p(x) and q(x) are polynomial and q(x) cannot equal zero or simply say it is a function gotten when we divides one polynomial by another. in real life, rational functions are often used in modeling more complex equations in science and engineering.From the above we can therefore say that the answer The two question that I want to ask to clarify the process of translating real life situation to rational function are

An analytical laboratory is asked to evaluate the claim that the concentration of the active ingredient in a specimen is 86%. The lab makes 3 repeated analyses of the specimen. The sample mean result is 0.8708. The true concentration is the mean m of the population of all analyses of the specimen. The standard deviation of the analysis process is known to be LaTeX: \sigmaσ = 0.0068. Is there significant evidence at the 1% level that LaTeX: \muμ is different than 0.86? (assume normality)
Answer:
Decision rule
Reject null hypothesis
Conclusion
There is significance evidence that the true mean is different from 0.86
Step-by-step explanation:
From the question we are told that
The population mean [tex]\mu = 0.86[/tex]
The sample is mean is [tex]\= x = 0.8708[/tex]
The standard deviation is [tex]\sigma = 0.0068[/tex]
The level of significance is [tex]\alpha = 0.01[/tex]
The sample size n = 3
The null hypothesis is [tex]\mu = 0.86[/tex]
The alternative hypothesis is [tex]\mu \ne 0.86[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{\= x - \mu }{ \frac{\sigma}{\sqrt{n} } }[/tex]
=> [tex]z = \frac{ 0.8708 - 0.86 }{ \frac{0.0068}{\sqrt{3} } }[/tex]
=> [tex]z = 2.751 [/tex]
Generally p- value is mathematically represented as
[tex]p-value = 2 P(z >2.751 )[/tex]
From the z-table
[tex]P(z >2.751 ) = 0.0029707[/tex]
So
[tex]p-value = 2 * 0.0029707[/tex]
=> [tex]p-value = 0.00594 [/tex]
From the obtained question we see that [tex]p-value < \alpha[/tex]
Hence we reject the null hypothesis

Answer:
1. see the first attachment for a graph; quadrants I, II, III; vertex (-3, -4); x-intercepts -5, -1; graph is dashed line, shaded inside the parabola, which opens up
2. see the second attachment for a graph; all quadrants; vertex (1, 2); x-intercepts 1±√2; graph is a solid line, shaded outside the parabola, which opens down; (-7, 0) is a solution
Step-by-step explanation:
1. The boundary expression is in vertex form, so the vertex can be read directly.
y = (x -h)^2 +k . . . . . . parabola with vertex (h, k)
y > (x +3)^2 -4 . . . . . (h, k) = (-3, -4)
The leading coefficient is +1, a positive number, so the parabola opens up. The relation is y > ( ), so values of y above the dashed line will be shaded. Those values are inside the parabola. The points (0, 0) and (-7, 0) are not in the shaded area, so are not solutions.
__
2. Again, the boundary expression is in vertex form, so the vertex can be read directly.
y ≥ -(x -1)^2 +2 . . . . . (h, k) = (1, 2)
The x-intercepts are found by solving for x when y=0:
0 = -(x -1)^2 +2
x -1 = ±√2
x = 1±√2
The leading coefficient is -1, so the parabola opens downward. The relation is y ≥ ( ), so y-values above the solid line will be shaded. Those values are outside the parabola. Point (0, 0) is not a solution. Point (-7, 0) is a solution.
_____
Additional comment
As with the graph of any inequality, the boundary line is solid when the "or equal to" case is part of the relation. If the relation is strictly "greater than" or "less than", then the boundary line is dashed.
