Answers
Answer:
The biggest - the smallest
612-120=492
Answer:
612 - 120=492
Step-by-step explanation:
to find the range the formula is to list the data set from smallest to largest, then subtract the smallest from the largest. 120, 145, 212, 349, 515, 590, 612= 612 - 120= 492

A group of students was randomly divided into two subgroups. One subgroup took a test in the morning, and the other took the same test in the afternoon. This table shows the results. Compare the probability that a student will pass the test in the morning with the probability that a student will pass the test in the afternoon. Draw a conclusin based on your results.
Answers
The probability of P (pass | afternoon) is 0.37 and the probability of P(pass | afternoon) is 0.71 and the probability of P (pass | afternoon) has greater chance of passing it than the probability of P (pass | afternoon)
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
From the data given:
P(pass | Morning) = 28/75 = 0.37
P(pass | afternoon) = 53/75 = 0.706 ≈ 0.71
Thus, the probability of P(pass | afternoon) has greater chance of passing it than the probability of P(pass | afternoon).

Find the value of y…
Answers
Answer:
y = 94
Step-by-step explanation:
Linear Pair:
The two adjacent angles whose non common arms form a straight line is called linear pair. They add up to 180
2x + 36 = 180 {linear pair}
2x = 180 - 36
2x = 144
2x = 144°
Sum of all angles of a n-sided polygon = (n-2)*180
= ( 6-2)*180
= 4 * 180
= 720
y + 144 + 111 + 105 + 165 + 101 = 720
y + 626 = 720
y = 720 - 626
[tex]\sf \boxed{y = 94^ \circ}[/tex]
Answer:
94°
Step-by-step explanation:
2x + 36 = 180 (angles on a straight line)
2x = 180 - 36
2x = 144
2x = 144°
Sum of all angles of a n-sided polygon = (n-2)×180 = ( 6-2)×180
= 4 × 180
= 720
y + 144 + 111 + 105 + 165 + 101 = 720
y + 626 = 720
y = 720 - 626
y=94 °

Answers
Step-by-step explanation:
1.
when 3 coins are flipped the following outcomes are possible
h = heads, t = tails
h h h
h h t
h t h
h t t
t h h
t h t
t t h
t t t
yes, there have to be 8 options, because we have 3 positions with 2 possible outcomes. that means
2×2×2 = 2³ = 8 possibilities.
2.
at least 2 tails means 2 or 3 t in the list item :
h t t
t h t
t t h
t t t
3.
so, 4 out of the 8 possible outcomes. the probability is then therefore
4/8 = 1/2 = 0.5

Answers
Answer:
equate the two euations
y = 2x - 1 multiply by 4
4y = 8x - 4 equate with the second equation
5x - 4y = 1
5x = 8x - 4 + 1
8x - 5x = 3
3x = 3
x = 1
substitute for x in any of the two equations
y = 2x - 1
y = 2(1) - 1
y = 2 - 1
y = 1
Therefore, according the solution we have got.
Yes, (1,1) is a solution to the system.

The answer is
for parallel : y= 4/7-5x/7
for perpendicular: y=10+7x/5
What is slope- intercept equations?The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It's usually easy to graph a line using y=mx+b.
Given line: 5x+7y=9
when our intersection point is (5,-3) the constant
5x+7y
= 5(5)+7(-3)
= 25-21
=4
hence, 5x+7y=4
slope intercept form
7y= 4-5x
y= 4/7-5x/7
Now, for perpendicular lines:
swap the coefficients on x and y with negative sign of x in 5x+7y=9
7x-5y= constant
again, when our intersection point is (5,-3) the constant must be
7x-5y
= 7(5)-5(-3)
=35+15
=50
7x-5y=50
slope intercept form so we solve for y:
y= (50+7x)/5
y=10+7x/5

Explanation:A linear function shall increase linearly. Here due to mass differences between points, it is visible that it is not a linear function.
There is a better way to understand what type of equation it is after plotting the coordinates on the graph.
Look at the attachment!After looking so, we can determine this as quadratic function.
** Not a exponential, inverse, linear function **
To find equation:Quadratic function: y = a(x - h)² + k
Locate (h, k) = (2, -4)
Take any other suitable point for example = (0, 0)
Insert values to find (a),
a(0 - 2)² - 4 = 0
4a = 4
a = 1
Now Join together: y = 1(x - 2)² - 4 --- Quadratic Equation
Exponential
It should be a parabola
The best shortcut trick is the fact about the parabola is that parabola is symmetric and axis of symmetry goes through vertex
So on both sides of vertex i e same distance on x from vertex the two x values have same y value .
Observe the table and find similar y values
(0,0) and (4,0)(1,-3) and (3,-3)FIND midpoint of x which is axis of symmetry
0+4/2=21+3/2=2We have been sured axis of symmetry is at x=2
Vertex (2,-4)Form equation
y=a(x-h)²+ky=a(x-2)²-4Put (5,5)
5=a(5-2)²-45=a(3²)-49a-4=59a=9a=9Final equation
y=(x-2)²-4
