Using the function f (x) = 400 – 15x, where f(x) = the remaining pounds of grain in the truck, and (x) represents the amount of buckets taken out:
Calculate how many buckets it will take until their is 50 pounds of grain remaining.
Answer:
[tex]{ \tt{f(x) = 400 - 15x}} \\ { \boxed{ \tt{when \: f(x )\: is \: 50}}} \\ 400 - 15x = 50 \\ 15x = 400 - 50 \\ 15x = 350 \\ x = 23.3 \approx23 \: buckets \\ \\ { \underline{ \blue{ \tt{becker \: jnr}}}}[/tex]

For this data set, there is an outlier. The outlier is four.
This is representing a small number of assignments required in math class that month.
This means that the correct answer is B.
Answer:
B
Step-by-step explanation:
The answer should be B or the second choice because the number 4 is unusually low compared to the rest of homework assignments given in the other math classes for that month. I made a graph to show how the number 4 is not near the number of homework assignments given in the other math classes.
If you think I missed something or made a mistake, please let me know.

Step-by-step explanation:
How many different committees can be formed from 12 teachers and 43 students if the committee consists of 3 teachers and 4 students?
The committee of 7 members can be selected in BLANK
different ways.
Answer:
[tex] \displaystyle 27150200[/tex]
Step-by-step explanation:
we are two conditions
committees can be formed from 12 teachers and 43 studentsthe committee consists of 3 teachers and 4 studentsIn choosing a committee, order doesn't matter; in case of teachers we need the number of combinations of 3 people chosen from 12
remember that,
[tex] \displaystyle\binom{n}{r} = \frac{n!}{r!(n - r)!} [/tex]
with the condition we obtain that,
[tex]n = 12[/tex][tex]r = 3[/tex]therefore substitute:
[tex] \displaystyle\binom{12}{3} = \frac{12!}{3!(12 - 3)!} [/tex]
simplify Parentheses:
[tex] \displaystyle\binom{12}{3} = \frac{12!}{3! \cdot9!} [/tex]
rewrite:
[tex] \rm \displaystyle\binom{12}{3} = \frac{12 \times 11 \times 10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1}{(1 \times 2 \times 3 )\cdot1 \times 2 \times 3 \times 4 \times 5 \times 6 \times 7 \times 8 \times 9} [/tex]
reduce fraction:
[tex] \rm \displaystyle\binom{12}{3} = \frac{12 \times 11 \times 10}{1 \times 2 \times 3 } [/tex]
rewrite 12 and 10:
[tex] \rm \displaystyle\binom{12}{3} = \frac{3 \times 2 \times 2 \times 11 \times 10}{1 \times 2 \times 3 } [/tex]
reduce fraction:
[tex] \rm \displaystyle\binom{12}{3} = 2 \times 11 \times 10[/tex]
simplify multiplication:
[tex] \rm \displaystyle\binom{12}{3} = 220[/tex]
In case of students we need the number of combinations of 4 students choosen from 43 therefore,
[tex] \displaystyle\binom{43}{4} = \frac{43!}{4!(43 - 4)!} [/tex]
simplify which yields:
[tex] \displaystyle\binom{43}{4} = 123410[/tex]
hence,
The committee of 7 members can be selected in BLANK different ways is
[tex] \displaystyle 123410 \times 220[/tex]
[tex] \displaystyle \boxed{27150200}[/tex]

what are the value of x in the equation x^2+4-1 =0
Answer:
x = ±sqrt(3) i
Step-by-step explanation:
x^2+4-1 =0
Combine like terms
x^2 +3 = 0
Subtract 3 from each side
x^2 +3-3 = 0-3
x^2 = -3
Take the square root of each side
sqrt(x^2) = sqrt(-3)
x = ±sqrt(3) sqrt(-1)
x = ±sqrt(3) i
How many liters are equal to 3,167 milliliters? Use the placement of the decimal point when dividing by a power of 10 to help you solve.
Answer:
3.167 liters
Step-by-step explanation:
1 liter = 1,000 milliliters
3,167 milliliters * 1liter/1,000milliliters = 3.167 liters

h(x)=x^3 -4x g(x)=x+2 find (h/g) (x)
Answer:
(h/g)(x) = x² - 2x
Step-by-step explanation:
h(x) = x³ - 4x
g(x) = x + 2
(h/g)(x) = h(x)/g(x) = (x³ - 4x) / (x + 2) = x² - 2x

Step-by-step explanation:
The sides of a triangle are x cm, (x -1) cm and (x+2) cm. IF the perimeter is 31 cm, then the SHORTEST side is
Answer:
9 cm
Step-by-step explanation:
Applying,
P = a+b+c................. Equation 1
Where P = Perimeter of the triangle, a, b,c are the three sides of the triangle respectively.
From the question,
Given: P = 31 cm, a = x cm, b = (x-1) cm, c = (x+2) cm
Substitute these values into equation 1, and solve for x
31 = x+(x-1)+(x+2)
31 = 3x+1
3x+1 = 31
3x = 31-1
3x = 30
divide both side by 3 to get x
3x/3 = 30/3
x = 10.
Therefore, the sides of the triangle are
a = x = 10 cm,
b = (x-1) = (10-1) = 9 cm
c = (x+2) = (10+2) cm = 12 cm
Hence the shortest side is 9 cm

Determine wether the lines are parallel perpendicular or neither
Answer:
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.

the sum of the three numbers is 94. The second number is 2 times the third. The first number is 6 more than the third. what are the numbers?
Answer:
28, 44, 22
Step-by-step explanation:
a+b+c = 94
2×c = b
a = c+6
=>
c+6 + 2×c + c = 94
4×c + 6 = 94
4×c = 88
c = 22
=>
b = 2×22 = 44
a = 22 + 6 = 28

The quotient of a number and - 2/3 is -9/10
What is the number?
1 7/20
3/5
29/30
20/27
Answer:
n = 3/5
Step-by-step explanation:
Represent this quotient as:
n
---------
-2/3
and set it equal to -9/10:
n -9
--------- = -------
-2/3 10
Cross multiplication yields:
10n = 6, so that n = 6/10 or n = 3/5
