Which table corresponds to the function y = -3x + 11?
Answer:
im not a 100% sure but i think its the 3rd one
The third table represents the linear function y = -3x + 11 so option (C) is correct.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
As per the given function,
y = -3x + 11
Put x = 0
y = -3 x 0 + 11 = 11
Put x = 1
y = -3(1) + 11 = 8
Put x = 2
y = -3 x 2 + 11 = 5
Since the values in table third are satisfied thus it will be correct.
Hence "The linear equation for the third table is y = -3x + 11.".

Angie, Keisha and Chen shared 125 stickers among themselves. Keisha and Chen received an equal number of stickers and Angie received one less sticker. How many stickers did Keisha receive?
Answer:
42 stickers
Step-by-step explanation:
Let
x = number of stickers Keisha and chen received
x - 1 = number of stickers Angie received
Total stickers = 125
125 = x + x + (x - 1)
125 = 2x + x - 1
125 + 1 = 3x
126 = 3x
x = 126/3
x = 42 stickers
x = number of stickers Keisha and chen received = 42 stickers
x - 1 = number of stickers Angie received = 42 - 1 = 41 stickers
find the measurement of sides
Answer:
(a) a ≈ 22.7 meters, (b) c ≈ 10.6 meters, (c) ∠A = 65°
Step-by-step explanation:
assuming side a/c is side BC/AB since it's opposite of angle A/C
(a) SOH CAH(cos = adjacent side/hypotenuse) TOA
=> cos (25°) = BC/AC or a/b
=> cos (25°) = a/25
=> a = cos (25°) × 25
=> a ≈ 22.7
(b) SOH(sin = opposite side/hypotenuse) CAH TOA
=> sin (25°) = AB/AC or c/b
=> sin (25°) = c/25
=> c = sin (25°) × 25
=> c ≈ 10.6
(c) 180° - 25° - 90°(the right angle) = 65°

¿Cuál es el volumen en pulgadas cúbicas de una esfera cuya circunferencia mide 64 pulgadas?
Answer:
4445.18 pulgadas cúbicas
Step-by-step explanation:
Paso 1
La fórmula para la circunferencia de una esfera = 2πr
Circunferencia de una esfera = 64 pulgadas
Por eso,
64 = 2πr
Por lo tanto, encontramos r
Dividir ambos lados por 2π
64 / 2π = 2πr / 2π
r = 10.185916358 pulgadas
Radio r = 10.2 pulgadas
Paso 2
Volumen de una esfera
= 4/3 × π × r³
r = 10.2 pulgadas
Por lo tanto, 4/3 × π × (10.2) ³
= 4445.18 pulgadas cúbicas
Por lo tanto, el volumen en pulgadas cúbicas de una esfera = 4445.18 pulgadas cúbicas

A phone company offers two monthly plans. Plan A costs $12 plus an additional $0.16 for each minute of calls. Plan B costs $29 plus an additional $0.12 for
each minute of calls.
For what amount of calling do the two plans cost the same?
What is the cost when the two plans cost the same?
Answer:
425 min$80Step-by-step explanation:
The equation to reflect the monthly plans:
Plan A f(x) = 0.16x + 12Plan B g(x) = 0.12x + 29We need to find the value of x when f(x) = g(x):
0.16x + 12 = 0.12x + 290.16x - 0.12x = 29 - 120.04x = 17x = 17/0.04x = 425 minutesThe cost is:
$0.16*425 + $12 = $80If we put on equations
y=0.16x+12y=0.12x+29Amount of calling is x and cost is y
solve
0.16x+12=0.12x+290.04x=17x=17/0.04x=425minCost
0.12(425)+29=$80The average distance from the sun to the planet Neptune is 2,795,080,000 miles. Write this in distance word form

Whats 1/7 + 3/4 ?
Please help me?
Answer:
25/28
Step-by-step explanation:
28 is the greatest common factor, found by multiplying 7 by 4 (the denominators)
1/7 = 4/28
3/4 = 21/28
21/28 + 4/28 = 25/28
An Brainly Question:
Whats 1/7 + 3/4 ?
Answer:
25/28
Step-by-step explanation:
Can you add yet? Nope! The denominators don't match. We need a common denominator. So next we take both denominators and multiply them. Next, take each numerator and multiply it by the denominator of the other term.
So, we multiply 1 by 4, and get 4, then we multiply 7 by 4 and get 28.
Let's add

Step 1
Can you add yet? Nope! The denominators don't match. We need a common denominator. So next we take both denominators and multiply them. Next, take each numerator and multiply it by the denominator of the other term.
So, we multiply 1 by 4, and get 4, then we multiply 7 by 4 and get 28.
1/7 times 4
Now for the second term. You multiply 3 by 7, and get 21, then multiply 7 by 4 and get 28.
3/4 times 7
We now have a new problem, that looks like this:
4
28
+
21
28
Step 2
Since our denominators match, we can add the numerators.
4 + 21 = 25
That gives us the sum, which is
25
28
Step 3
Now, do we need to simplify this fraction?
First, we attempt to divide it by 2...
Nope! So now we try the next greatest prime number, 3...
Nope! So now we try the next greatest prime number, 5...
Nope! So now we try the next greatest prime number, 7...
Nope! So now we try the next greatest prime number, 11...
Nope! So now we try the next greatest prime number, 13...
Nope! So now we try the next greatest prime number, 17...
Nope! So now we try the next greatest prime number, 19...
Nope! So now we try the next greatest prime number, 23...
Nope! So now we try the next greatest prime number, 29...
No good. 29 is larger than 25. So we're done reducing.
There you have it! Here's the final answer to 1/7 + 3/4

You ARE SUPPOSED TO BE IN BRAINLY.IN FOR 5th Grade and LESSPlease (You can put answer only) Find the distance between the two points rounding to the nearest tenth (if necessary).
(4, -8) and (2, -4)
Answer:
12.16 u
Step-by-step explanation:
Given :-
Two points (4,-8) and (2,-4) is given to us.And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,
[tex]:\implies[/tex] D = √{(x2-x1)² + (y2-y1)²}
[tex]:\implies[/tex] D =√[ (4-2)² +(8+4)²]
[tex]:\implies[/tex] D =√[ 2² +12²]
[tex]:\implies[/tex] D =√[ 4 +144]
[tex]:\implies[/tex] D = 12.16
Hence the distance between the two points is 12.16 units .does it represent the range, mode, median, or mean
Answer:
median
Step-by-step explanation:
in a box plot, it does not represent the mean, just so you know.
mode = largest number.
range = difference between largest number and smallest number

Step-by-step explanation:
C(n) = 5n, 0 ≤ n ≤10 You would use this formula because 6 is greater than 0 but less than 10.
C(n) = 5n, 0 ≤ n ≤10 ← You can just ignore the 0≤ n ≤10 part.
C(6) = 5(6) Input the value 6 as x.
C(6) = 30
The answer is that 6 shirts costs 30 dollars.

A rep hockey team has two goalies. Goalie A has a save percentage of 0.92 and Goalie B has a save percentage of 0.89. If goalie A plays 75 percent of the games and goalie B plays 25 percent of the games then: a) Determine the probability that a save has been made by either goalie A or goalie B. b) If a save has been made, what is the probability that is was goalie A? c) If a goal was let in, what is the probability it was goalie B?
Answer:
a) 0.9125
b) 0.756
c) 0.314
Step-by-step explanation:
The save percentage of Goalie A = 0.92
The save percentage of Goalie B = 0.89
The percentage of the games Goalie A plays = 75 percent
The percentage of the games Goalie B plays = 25 percent
a) The probability that a save has been made by either Goalie A or Goalie B
Therefore we get;
The probability that Goalie A made a save, P(A) = 0.92 × 0.75 = 0.69
The probability that Goalie B made a save, P(B) = 0.89 × 0.25 = 0.2225
For mutually exclusive events, we have;
P(A) or P(B) = P(A) + P(B)
∴ P(A) or P(B) = 0.69 + 0.2225 = 0.9125
The probability that a save has been made by either Goalie A or Goalie B, P(A) or P(B) = 0.9125
b) Where there are 10,000 attempts, made evenly in all games, we have;
The number of attempts made with Goalie A playing = 10,000 × 0.75 = 7,500
The number of saves Goalie A makes = 0.92 × 7,500 = 6,900
The number of saves for 10,000 attempt = (P(A) or P(B)) × 10,000 = 0.9125 × 10,000
The number of saves for 10,000 attempt = 9,125
∴ The probability that Goalie A saves = 6,900/9,125 ≈ 0.756
c) Out of the 2,500 attempts at Goalie B, the number of goals let in is given as follows;
P(Goal B) = 2,500 - 2,500 × 0.89 = 275
The number of goals let in by Goalie A, we have;
P(Goal A) = 7,500 - 7,500 × 0.92 = 600
Therefore, the total number of goals let in = 300 + 275 = 875
The probability that the goals was let in by Goalie B = 275/875 = 11/35 ≈ 0.314.
