Given,
[tex]x = 7[/tex]
Substitute the value of 'x' in the equation 3x (x - 2).
One way :-
[tex]3x(x - 2) \\ = 3 \times 7(7 - 2) \\ = 21(5) \\ = 21 \times 5 \\ = 105[/tex]
Second way :-
[tex]3x(x - 2) \\ = 3x {}^{2} - 6x \\ = 3 \times (7) {}^{2} - 6(7) \\ = (3 \times 49) - (6 \times 7) \\ = 147 - 42 \\ = 105[/tex]
✐ The answer is 105.

In a comection with a criminal investigation
the police question of men allot whom are
tall, slim or bald, There are 32 tall men , 20
who are tall and slim 23 who are tall
and bald, 24 who are slim and bold
6 who are slim but not tall a bold
and a who are tall but not slim or bald.
Find the number of men questioned who have
all three characteristics
b) work out the number who are bald but
not tall a silm.
Answer:
We have
n[T]=4+20-x+x+23-x
32=47-x
x=47-32
x=15
so
the number of men questioned who have
the number of men questioned who haveall three characteristics is 15.
again
n[S]=6+20-x+x+24-x=50-x=50-15=35
again
we have
n[U]=n[T]+n[s]+N only [ B]
54=32+35+N only [ B]-n[T and S]
N only [ B]=54-67+20=7
who are bald but
who are bald butnot tall a slim is 7.
can someone please solve this? I clicked on homework help and it wasn't much help. I'm trying to turn in as much missing assignments as I can before school ends on Thursday. Thank you!
Answer:
One proportion to solve is 8/18 = x/8Exact answer as a fraction: x = 32/9Approximate answer in decimal form: x = 3.556In reality, the 5's go on forever, but we have to round off somewhere.
========================================================
Explanation:
Break up the triangles as your teacher recommends. See the diagram below as to what I mean.
The smaller triangle has A = 8 as the horizontal side, and B = x as the vertical side
The larger triangle has C = 10+8 = 18 as the horizontal aside, and D = 8 as the vertical side.
We can form the proportion A/C = B/D.
A/C connects the horizontal sides (small/large) while B/D has the vertical sides tied together. The order of division is the same small over large. You could do large over small, but make sure you keep both sides consistent.
-----------------
Let's solve for x
A/C = B/D
8/18 = x/8
8*8 = 18*x .... cross multiply
64 = 18x
18x = 64
x = 64/18 .... divide both sides by 18
x = 32/9 exactly in fraction form
x = 3.556 approximately in decimal form
-------------------
Another proportion you can solve is A/B = C/D and you should get the same x value. It's the same as A/C = B/D because the B and C swap places. There are many other approaches you could take using different proportions.

When Victoria goes bowling, her scores are normally distributed with a mean of 130
and a standard deviation of 11. What is the probability that the next game Victoria
bowls, her score will be between 123 and 130, to the nearest thousandth?
Answer:
0.2377 or about a 23.77% chance
Step-by-step explanation:
P(123<X<130) = normalcdf(123,130,130,11) = 0.2377303466 ≈ 0.2377
Therefore, the probability that the next game Victoria bowls, her score will be between 123 and 130 is 0.2377 or about a 23.77% chance

find the surface area, and please show me steps so i can understand this myself !
Answer:
The surface area of the triangular prism is approximately 401.582 square feet.
Step-by-step explanation:
The figure represents a triangular prism, the procedure for calculating the surface area of the entire figure consists in adding the areas of each face (3 rectangles and 2 triangles):
[tex]A = 2\cdot \left[\frac{1}{2}\cdot (9\,ft)\cdot (4\,ft)\right] + (16\,ft)\cdot (4\,ft) + (9\,ft)\cdot (16\,ft) + (16\,ft)\cdot \sqrt{(9\,ft)^{2}+(4\,ft)^{2}}[/tex][tex]A \approx 401.582\,ft^{2}[/tex]
The surface area of the triangular prism is approximately 401.582 square feet.

1. You go to the local Sport Grill for quarter wings day.
All chicken wings are $0.25. Your waiter also announces
that for your stay there will be an additional 20%
discount on wings. Your table of friends stays there for
2 hours and eats a total of 78 wings. How much do you
expect the bill to be for your wings?
na
Answer:
If the 20% discount is by the hour then the answer would be $11.70 I think.
0.25x78= 19.50
19.50x0.20(20%)= 3.90
19.50-3.90-3.90= 11.70

Hi there!
A function is a set of ordered pairs that do not have same x-values.
In a set of ordered pairs, If two or more ordered pairs have same x-values, they are not considered as a function but rather a relation instead.
From the question above, you notice that two of the choices have same x-values and others don't have.
The relations that are not functions are the second choice and fourth choice because two ordered pairs have same x-values.
Any questions can be asked through comment.
Furthermore, a function is also a relation but a relation isn't always a function.
Hope this helps, and Happy Learning! :)

Alex should use Graph A for the presentation as it shows the number of faulty products as a decrease on the graph
What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let graph A shows the product quality with number of faulty products over the period of months
And , let graph B shows the product quality with number of faulty products over the period of months
Now , the line is decreasing in a steady manner in graph A as the number of faulty products is decreasing at a nominal rate
Hence , graph A is best for presentation

Solve for p.
2p + 1=1
5p + 6=7
Answer:
-1/9
Step-by-step explanation:
We need to solve out and find out the value of p . The given equations is.
=> 2p + 1/ 5p + 6 = 1/7
=> 7 ( 2p + 1) = 5p + 6
=> 14p + 7 = 5p + 6
=> 14p - 5p = 6-7
=> 9p = -1
=> p = -1/9
• Hence the value of p is -1/9

The graph shown below expresses a radical function that can be written in the form f(x) = a * (x + k) ^ (1 / n) + c does the graph tell you about the value of k in this function ? A. k equals zero.
B. k is less than zero.
C. k is greater than zero.
D. It is not possible to tell whether k is greater than or less than zero.
Answer:
C
Step-by-step explanation:
Just took the quiz
Based on the graphed values of f(x) and independent variable x, the graph shows that C. k is greater than zero.
What is the value of k?We have a c value of -1 which is where the y axis is intercepted.
We know that k isn't zero because the x and y values are not the same. We can also tell that k is not less than 0 because if it was, the f(x) for the smaller x value would lead to a larger f(x) value.
The only logical conclusion therefore, is that k is greater than zero.

x+4/9=3/4 what is x?
Answer:
11/36
Step-by-step explanation:
To answer this, you must first convert your fractions to have the same denominators (so you can add and subtract them). I switched it to 36ths. So, the equation would be x+16/36=27/36. When you subtract 16/36 from 27/36 you get 11/36. This cannot be simplified, so 11/36 is the answer. I hope it helps.
