Step-by-step explanation:
a) 0.6406; b) 1.000; c) C. The probability from part (a) is more relevant because it shows the proportion of male passengers that will not need to bend; d) B. Since men are generally taller than women, a design that accommodates a suitable proportion of men will necessarily accommodate a greater proportion of women.

f (x) = (x - 5)^2 and f (x) = x^2-5
Answer:
You are squaring x and -5 on the first equation, and on the second equation you are just squaring x and subtracting 5.
Step-by-step explanation:
And since on the first equation x and -5 are in parenthesis that means that the square goes to both of them.
And the second one there is no parenthesis so the square only goes to the x.

[MA]:
1. 265 r 37
2. 190 r 34
3. 3,830 r 17
4. 875 r 11
The explanation:
1.
42 x 2 = 84
84 - 11167 = 276 (or "?")
276 - 252 = 247 - 210 = 37
2.
72 x 1 = 72
13714 - 72 = 651 - 648 = 34
3.
24 x 3 = 72
91937 - 72 = 199 - 192 = 73 - 72 = 17
4.
70 x 8 = 560
61261 - 560 - 526 - 490 - 361 - 350 = 11
Writer's note: I hope this helps you.

After divide, solution of the expression are,
42 divided by 11167 = 0.0037
72 divided by 13714 = 0.0052
24 divided by 91937 = 0.00026
70 divided by 61261 = 0.0011
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
42 divided by 11167
72 divided by 13714
24 divided by 91937
70 divided by 61261
Now, We can simplify as;
⇒ 42 ÷ 11167
⇒ 42 / 11167
⇒ 0.0037
⇒ 72 ÷ 13714
⇒ 72 / 13714
⇒ 0.0052
⇒ 24 ÷ 91937
⇒ 24 / 91937
⇒ 0.00026
⇒ 70 ÷ 61261
⇒ 70 / 61261
⇒ 0.0011

$0.28 is what percent of $3.20?
Answer:
8.75%
Step-by-step explanation:
Do the ordered pairs below represent a relation, a function, both a relation and a function, or neither a relation nor a function?
(-4,0) , (2,-6) , (4,-8) , (10,-14) A. Relation only
B. Neither a relation nor a function
C. Function only
D. Both a relation and a function
=======================================================
Explanation:
A relation is any set of (x,y) points usually with some rule tying them together. Though that rule doesn't have to be present. We could simply have a set of points. The set of points we are given is a relation.
A function occurs when we don't repeat the x value. Visually if we had two points stacked on top of each other, then we wouldn't have a function since it fails the vertical line test. A function happens when all x inputs leads to exactly one y output. If we had say { (-4,0), (2,-6), (-4,3) } then this wouldn't be a function since x = -4 repeats itself.
Since none of the x values repeat themselves in our given set, this means we have a function.
Side note: Any function is a relation, but not the other way around.

**I want to mention that please use asterisk (*) symbol for multiplication as multiplication symbol x and variable x look the exact same
Your question is
3*4+2*3-5*2+4*2+6x-2x-3*4+7x-3*3
First calculate each term getting
=12+6-10+8+6x-2x-12+7x-9
Now combine like term which means adding all of the constant together and all of the term containing variable x together
=11x-5
Therefore 11x-5 is the answer to the expression.

Sara's score in the sixth test is 98.
HOW TO CALCULATE TOTAL FROM MEAN?The mean of a set of data can be calculated by dividing the total sum by the number of data given.
According to this question, Sara is said to have a mean score of 62 in 5 tests and another mean score of 68 in 6 tests.
First total score = 62 × 5 = 310Second total score = 68 × 6 = 408Therefore, Sara's score in the sixth test can be calculated by subtracting 310 from 408 to give 98.

O The domain of f(x) is restricted such that x = 0, so
the domain of f'(x) is restricted such that y 2 0.
O The range of f(x) includes values such that y 1, so
the domain of f'(x) includes values such that x 2 1.
According to the table the inverse of f(x) does not have an x-intercept
Functions and valuesThe y-intercept of the point where the x-values are zero. From the table of the function f(x), the function has a y-intercept at the point where x = 0
For the table of its inverse, there is no point where y is zero, hence the inverse of the function has no x-intercept
We can therefore conclude that according to the table the inverse of f(x) does not have an x-intercept

5. 8x + 4y = -5
8x + 4y = 12
Solve it algebraically
Answer:
solving for x:
8x + 4y = -5
[tex]x = \frac{ - 1}{2} y + \frac{ - 5}{8} [/tex]
and 8x + 4y = 12
[tex]x = \frac{ - 1}{2} y + \frac{3}{2} [/tex]
solving for y:
8x + 4y = -5
[tex]y = - 2x + \frac{ - 5}{4} [/tex]
and 8x + 4y = 12
[tex]y = - 2x + 3[/tex]
Select the statements that are true for the graph of y=(x−1)2−6 .
Select all correct statements.
The vertex is (1, −6) .
The graph has a maximum.
The vertex is (−1, −6) .
The graph has a minimum.
Answer:
graph has a minimum ( looks like V or faces upward )
vertex is (1, −6)
Step-by-step explanation:
*** got to put ^ when typing exponents!!!
y=(x−1)^2−6
y=x^2-2x+1−6
y=x^2-2x-5
basic form is
y = ax^2+bx+c
x vertex = -b/2a
x vertex = -(-2)/2(1)
x vertex = 2/2
x vertex = 1
y vertex = plug x back into the equation
y vertex = y=(1)^2-2(1)-5
y vertex = y=1-2-5
y vertex = y=-6
vertex is (1, −6)
basic form is
y = ax^2+bx+c
if a is positive curve has a minimum means it looks like V or faces upward
if a is negative curve has a maximum means it looks like ^ or faces down
here a is positive so
graph has a minimum
