Step-by-step explanation:
A coin is flipped 80
times. It lands tails 47
times. What is the Probability
1/2 or 50% because each flip of a coin is independent from the last and a fair coin has an equal probably of landing on either side.
What is the distance between the points (−7, −3) and (−7, −9) ?
A 12 units
B 10 units
C 6 units
D 4 units
Answer:
C. 6 unitsStep-by-step explanation:
Since the points have same x- coordinate of -7, the distance is the difference in y - coordinates:
d = -3 - (-9) = -3 + 9 = 6Correct choice is C

Answer:
y = (5/2)x + 13/2
y = 3
y = -2x + 6
Step-by-step explanation:
The left part of the function which is a line sloping up to the right contains points (-3, -1) and (-1, 4) which can be read off the graph.
Since we have two points, we can find the equation.
You can use the slope formula given two points, but I will read it off the graph with rise and run.
Go from point (-3, -1) to point (-1, 4) by going up 5 (the rise) and going right 2 (the run).
slope = rise/run = 5/2
y = mx + b
y = (5/2)x + b
Use point (-1, 4) for x and y and solve for b.
4 = (5/2)(-1) + b
8/2 + 5/2 = b
b = 13/2
y = (5/2)x + 13/2
This is the first answer.
The middle part is a horizontal line in which every point has y-coordinate 3.
The equation is:
y = 3
This is the second answer.
The right part is the line that slopes down to the right. We can read two points easily. Use points (3, 0) and (2, 2).
Start at (3, 0). Go left 1 (run of -1) and up 2 (rise of 2). Now you are at point (2, 2).
slope = rise/run = 2/(-1) = -2
Now we find the y-intercept on the graph. After you get to (2, 2), keep moving with the same run and rise of the slope. Go left 1 and up 2 to point (1, 4). Go again left 1 and up 2 to (0, 6). Point (0, 6) is on the y-axis, so it is the y-intercept.
b = 6
y = mx + b
y = -2x + 6
This is the third answer.
Write the equation of a line that
goes through the points (3,7) and
(-3,5).
Answer:
[tex]y = mx + c \\ 7 = 3m + c \\ 5= - 3m + c \\ 2c = 12 \\ c = 6 \\ 7 = 3m + 6 \\ 3m = 1 \\ m = \frac{1}{3} \\ y = \frac{1}{3} x + 6[/tex]

Answer:
In 2x[tex]\geq[/tex]8 the answer is: x[tex]\geq[/tex]4
Step-by-step explanation:
If we look at the 2x[tex]\geq[/tex]8, we can easily solve it. We know that the [tex]\geq[/tex] symbol means greater than or equal to. If we go by greater than, it could be any number of numbers. However, we know that it is also possible equal. For this to be true, then whatever 2 is being multiplied by must possibly give a product of eight also. Because of this, we can use the knowledge that 2*4 equals 8. So we simply put it in. x must be greater than or equal four in order to make the statement true. Remember the greater to or equal than part. It could be more than four. We are just saying the minimum of x would be four.
4x - 5 =-11 + 3x
Pls help I need the answer fast
Answer:
x = -6
Step-by-step explanation:
You want to get x to only one side:
4x - 5 = -11 + 3x
-3x -3x
x - 5 = -11
Now move 5 to the right side:
x - 5 = -11
+5 +5
x = -6
Jackson bought an ultra-slim Television. The screen measures 13 cm in length and 12 cm in width. Television screen sizes are decided by the length of the diagonal. What is size of this screen? Round your answer to the nearest whole number.
Answer:
18 cm
Step-by-step explanation:
You can find the length of the diagonal by using the Pythagorean theorem.
a^2 + b^2 = c^2
12^2 + b^2 = c^2
144 + 169 = c^2
c^2 = 313
c = √313
c = 17.6918...
Answer: 18 cm

6. What is the value of x in the solution to the systems of linear equations shown below?
2x - 2y+z=3
5y-z= -31
x+ 3y + 2z = -21
Step-by-step explanation:
[tex]1) \: \: 2x - 2y + z = 3 \\ 2x = 3 + 2y - z \\ x = \frac{3 + 2y - z}{2} \\ \\ 2) \: \: \: not \: any \: \: \: x \: \: \: available \: \: \\ \\ 3) \: \: x + 3y + 2z = - 21 \\ x = - 21 - 3y - 2z[/tex]
Answer:
x= -5
Step-by-step explanation:
5y-z= -31, add z and 31 to both sides
5y+31 = z, substitute z in the other two given equations
2x - 2y+z=3
2x-2y +5y+31 = 3, combine like terms and subtract 31 from both sides
2x+3y = -28
x+ 3y + 2z = -21
x+3y +2(5y+31) = -21, distribute 2 over the addition parenthesis
x+3y +10y+62 = -21, combine like terms and subtract 62 from both sides
x+13y = -83
Now we have 2 equations with 2 variables x and y to solve
2x+3y = -28
x+13y = -83
Because we need to find x then from the first equation we can write that
3y = -2x-28, subtract 2x from both sides and the divide both sides by 3
y = (-2x-28)/3, substitute this in the second equation
x + [13(-2x-28)/3] = -83 , distribute 13 . over the subtraction parenthesis
(3x/3)+[(-26x - 364) /3= -83, find the common denominator
3x+[(-26x - 364) = -83*3 , cross multiply
3x -26x = -249 +364, add 364 to both sides
- 23x = 115, divide both sides by (-23)
x= -5

Anybody? need help asap
Answer:
x = -1
Step-by-step explanation:
5x + 3 -2x = 2(x + 1) >>> Simplify by combining terms
3x + 3 = 2x + 2 >>> Subtract 2x and 3 from both sides
x = -1

Answer:
a.
Scale Factor = 2
Reason:
Since, B is a scaled copy of A it's corresponding sides must be in proportion with that of A, and that proportion would be its scale factor.
I held their horizontal sides and compared them.
in case of A, the side is 2.5 and in case of B it's 5.
so, 5 divided by 2.5 gets you 2, that is the scale factor.
b.3, 5 (from left to right)
Solution:
[tex] \boxed{ \mathsf{ \frac{crsp. \: side \: of \: b}{crsp. \: side \: of \: a} = scale \: factor }}[/tex]
this also means
[tex] \boxed{ \mathfrak{crsp. \: side \: of \: b =( scale \: factor) \times \: crsp. \: side \: of \: a }}[/tex]
Scale factor = 2Using this we'll get the answer to the question marks
The corresponding side to 1.5 is the vertical one in B.=> corresponding side in B = 2 × 1.5
= 3
(this is the first question mark in order from left to right)
The corresponding side to 2.5 is:= 2 × 2.5
= 5
c.53° and 37° (from top to bottom)
Solution:
Scaled shapes have the same angle measures.
Reason:
When we scale two line segments meeting at a point, the lengths of the segments change but they still are part of the same pair of rays making the same angle.

(Question is in image below)
Answer:
92 more miles (D)
Step-by-step explanation:
I believe the answer is 92 more miles (d). So we know that Mr Klein is driving at a steady 60 miles per hour for 42 minutes. There are 60 minutes in an hour, so every minute they've driven a mile. Therefore, in 42 minutes, they've driven 42 hours. And then 134 - 42 is equal to 92, which is your final answer.

Angle A = 133 degrees
47 degrees and angle A are supplementary angles/a linear pair, which means that they add up to 180.
180 - 47 = 133
Angle B = 15 degrees
The sum of the interior angles in a triangle is 180.
a + 32 + b = 180
133 + 32 + b = 180
b = 15
Angle D = 58 degrees
32 degrees and angle D are complementary angles, which means that they add up to 90.
90 - 32 = 58
Angle C = 75 degrees
The sum of the interior angles in a triangle is 180.
c + d + 47 = 180
c + 58 + 47 = 180
c = 75
Hope this helps!! :)

Macario is making 12 pounds of nut mixture with macadamia nuts and almonds. Macadamia nuts cost $9 per pound, and
almonds cost $5.25 per pound. How many pounds of macadamia nuts and how many pounds of almonds should Macario
use for the mixture to cost $6.50 per pound to make?
Answer:
Marcario should use 4 pounds of macadamia nuts and 8 pounds of almonds.
Step-by-step explanation:
Marcario should use 4 pounds of macadamia nuts and 8 pounds of almonds. Explanation given cost of macadamia nuts per pound=$9
cost of almond nuts per pound=$5.25
cost of the mixture per pound=$6.5
total pounds of the mixture to be made=12
let the pounds of macadamia nuts=x
pounds of almond nuts=y
total pounds of nuts=x+y= 12
x + y = 12(1)
9x +5,25y = 6.5(x+y)
9x+5.25y=6.5*12
9x+5.25y=78(2)
solving (1) and (2)
x=4 y=8
