Answer:
B
Step-by-step explanation:
The lines marked with ||| are equal. That means that 2P + 7 equals 17
2P + 7 = 17 Subtract 7 from both sides.
2P + 7 - 7 = 17 - 7 Combine
2P = 10 Divide by 2
P = 5
3k - 5 and 28 are marked with one | That means that they are equal
3k - 5 = 28
3k = 28 + 5
3k = 33
k = 33/3
k = 11
The answer is B

Answer:
Step-by-step explanation:
Median: First write in ascending order. If number of data's is odd, median is the middle data.
If number of data's is even, then median = average of n/2th and (n+2)/2th term.
1) 1 , 3 , 5 , 5 , 6
Median = 5
2) 3,4,10,2,1
Ascending order: 1,2,3,4,10
Median = 3
3) 4, 5,7,11
Median = (5+7)/2 = 12/2 = 6
4) 1,1,2,6
Median = (1+2)/2 = 3/2 = 1.5
5) 2,2,3,3,,5,7
Median = 3+3/2 = 6/2 = 3
6)1,2,4,6,7,7
Median = (4+6)/2 = 10/2 = 5
7) 2,2,3,6,7,8
Median = (3+6)/2 = 9/2 = 4.5
8)1,2,3,14,17,18
Median = (3+14)/2 = 17/2 = 8.5
Mean= Sum of all the items÷ number of items
1)Mean = (1+2+3+2)÷4 = 8÷2 = 4
2)Mean=(4+3+2+4+2)÷5 = 15÷5 = 3
3)Mean = (5+4+6+1)÷4 = 16÷4 = 4
4)Mean = (2+5+1+4+7+5)÷6 = 24÷6 = 4
5)Mean =(10+11+9+12+8)÷5=50÷5 = 10
6)Mean = (1 + 2 + (-2)+1+(-2) )÷5 = -2÷5 = -0.4
7)Mean = (4+(-2)+3+(-3)+3)÷5 = 5÷5 = 1
8)Mean = (4+5.5+3+5.5)÷4=18÷4 = 4.5
Answer:
Median
1) 5
2) 3
3) 5+7=12/2=6
4)1+2=3/2=1.5
5)3+3=6/2=3
6) 4+6=10/2=5
7) 3+7=10/2=5
8)14+3=17/2=8.5
Mean
1) 2
2) 3
3)4
4)4
5) 10
6) 0
7) 1
8) 4.5
Step-by-step explanation:
Median is the middle number, make sure the list of in order from smallest to highest.
2) 1, 2, 3, 4, 10
if you have two numbers in the middle add them together then divide by 2
4) 1, 1, 2,6
5)2, 2, 3, 3, 5, 7
6) 1, 2, 4, 6, 7, 7
7)2, 2, 3, 7, 6,8
8)1, 2, 3, 14, 17, 18
Mean is when you add all the numbers together and divide by how many there are.
1) 1+3+2+2=8/4=2
Find the domain for the rational function f of x equals quantity x minus 1 end quantity divided by quantity x plus 3 end quantity.
(−∞, 1) (1, ∞)
(−∞, −1) (−1, ∞)
(−∞, 3) (3, ∞)
(−∞, −3) (−3, ∞)
Answer:
[tex]\mathrm{Domain\:of\:}\:\frac{x-1}{x+3}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x<-3\quad \mathrm{or}\quad \:x>-3\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:-3\right)\cup \left(-3,\:\infty \:\right)\end{bmatrix}[/tex]
Therefore, the 4th option i.e. (−∞, −3) (−3, ∞) is the correct answer.
Step-by-step explanation:
Given the expression
[tex]f\left(x\right)=\frac{x-1}{x+3}[/tex]
We know that the domain is the set of all the input or argument values for which is the function is real and defined.
From the given expression, we need to make sure the denominator of a rational function can be anything but 0, because 0 would make the function undefined.
Thus, we need to find undefined points such as:
x+3 = 0
x = -3
Therefore, the function domain must be:
x < -3 or x > -3
In other words,
[tex]\mathrm{Domain\:of\:}\:\frac{x-1}{x+3}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x<-3\quad \mathrm{or}\quad \:x>-3\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:-3\right)\cup \left(-3,\:\infty \:\right)\end{bmatrix}[/tex]
Therefore, the 4th option i.e. (−∞, −3) (−3, ∞) is the correct answer.

Answer:
[tex]\mathrm{A.\:}x+2y=a[/tex]
Step-by-step explanation:
In standard form [tex]ax+by=c[/tex], any point the line passes through will make the inequality true. We can simply use any point given to find the equation of the line:
We can write the following system of equations from two points from the table:
[tex]\begin{cases}d\cdot3a+e\cdot(-a)=f\cdot a\\d\cdot5a+e\cdot(-2a)=f\cdot a\end{cases}[/tex]
Solving, we get:
For [tex]a \notin 0[/tex],
[tex]d=1,\\e=2,\\f=1[/tex]
Therefore, our equation is:

Answer: the last one
Step-by-step explanation:
um so the set begins with 40 and ends with 100 (look at that on the number line)
and so the median is essentially that middle line in the box, which is around 80
i assume yk how to calculate medians so I calculated the median of the first and the last answer
the first one was like 70, and the last one was like 78.9 which is close enough to 80
so i think its the last one
Answer:
It is answer number four.
Step-by-step explanation:
40 and 100 represent the outliers so both numbers must be included.
80 must also be included as it is the mean or average test grade.

Answer:
The correct answer is,
a<9use the discrminant to determine all values of k which would result in the equation -3x^2-6x+k=0 having real,unequal roots. must be right ty helppp asap
Answer:
[tex]k>-3[/tex]
Step-by-step explanation:
We have the equation:
[tex]-3x^2-6x+k=0[/tex]
Where a = -3, b = -6, and c = k.
And we want to determine values of k such that the equation will have real, unequal roots.
In order for a quadratic equation to have real, unequal roots, the discriminant must be a real number greater than 0. Therefore:
[tex]b^2-4ac>0[/tex]
Substitute:
[tex](-6)^2-4(-3)(k)>0[/tex]
Simplify:
[tex]36+12k>0[/tex]
Solve for k:
[tex]12k > -36[/tex]
[tex]k>-3[/tex]
So, for all k greater than -3, our quadratic equation will have two real, unequal roots.
Notes:
If k is equal to -3, then we have two equal roots.
And if k is less than -3, then we have two complex roots.

Lake Michigan is one of five great lakes in north america.In summertime, lake Michigan recedes about 1/4 foot per hour. Lake Michigan is about 279 ft. In depth.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete. However, a possible question is "calculate the depth of the lake after certain number of hours (say 2 hours)"
Given
[tex]Rate = \frac{1}{4}ft/hr[/tex]
[tex]Depth = 279ft[/tex]
First, we calculate the depth receded.
If the rate is 1/4ft per hour
Then
The Depth receded in 2 hours is:
[tex]Receded = \frac{1}{4} * 2[/tex]
[tex]Receded = \frac{2}{4}[/tex]
[tex]Receded = 0.5ft[/tex]
The new depth is then calculated as:
[tex]New\ Depth = 279ft - 0.5ft[/tex]
[tex]New\ Depth = 278.5ft[/tex]

DECIMAL FORM ROUNDED TO THE NEAREST TENTH !
BRAINLEST to whoever right.
Answer:
The value of x = 65.4°
Step-by-step explanation:
Given
hypotenuse = 12
To determine
The value of ∠x = ?
Using the trigonometric ratio
cos x = adjacent / hypotenuse
here:
Adjacent of angle ∠x = 5hypotenuse = 12substituting adjacent = 5, hypotenuse = 12 in the formula
cos x = adjacent / hypotenuse
cos x = 5 / 12
x = arccos (5/12)
x = 65.4°
Therefore, the value of x = 65.4°
Answer:
The answer is 65.3 to the nearest tenth
Step-by-step explanation:
You'll use the Pythagoras theorem to find the unknown side first
then you'll use the sin rule to solve for x
Solve for y: 2x^2+2y=4x+2x^2-7. Show your work
Answer:
y = 2x - 3.5
Step-by-step explanation:
2x² + 2y = 4x + 2x² - 7
2y = 4x + 2x² - 7 - 2x²
2y = 4x - 7
y = (4x - 7) / 2
y = 2x - 3.5
2x² + 2y = 4x + 2x² - 7
4x + 2y = 4x + 2x² - 7
4x + 2y = 4x + 4x - 7
4x+2y=8x-7
2y = 4x - 7
solve the system of equations y = -2x and y = x - 3 what is the y value of your solution

Question :
1. Find the gradient of the tangent to the curve y = 2x²+5x-3 at the point where x = 1.
2. Find from first principle, the derivative of 3/x with respect to x
Answer:
dy/dx
= d/dx [2x² + 5x - 3]
= 4x + 5.
Hence at x = 1, dy/dx = 4(1) + 5 = 9.
The slope of the tangent is 9.
d/dx (3/x)
= d/dx (3x^-1)
= 3 * d/dx (x^-1)
= 3 * [-1 * x^(-2)]
= -3/x².

From the two triangles, it can be observed that;
m<BAC≅m<EDC (alternate angles)
m<ABC≅m<DEC (alternate angles)
m<BCA≅m<ECD (vertically opposite angles)
m<BAC + m<ABC + m<BCA = m<EDC + m<DEC + m<ECD = [tex]180^{o}[/tex] (sum of angles in a triangle)
