Answers
Answer:
-1
Step-by-step explanation:
Pick two points on the line
(0,2) and (2,0)
Using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 0-2)/(2-0)
= -2/2
= -1
Answer:
-1
Step-by-step explanation:
Use two points on the line to find the slope, using rise over run.
We can use the points (0, 2) and (2, 0).
From the first point to the other, the y value decreases by 2 and the x value increases by 2.
Use rise (change in y value) over run (change in x value):
-2 / 2
= -1
So, the slope is -1.

Let X1 and X2 be independent random variables. Suppose the mean and variance of X1 are 1 and 1, respectively. Suppose, the mean and variance of X2 are 4 and 8 respectively. What is the standard deviation of X2 - 3X1
Answers
Since X₁ and X₂ are independent, we have
Var[X₂ - 3X₁] = Var[X₂] + (-3)² Var[X₁]
Var[X₂ - 3X₁] = 8 + 9 × 1
Var[X₂ - 3X₁] = 17
Then the standard deviation of X₂ - 3X₁ is the square root of the variance, √17.

Which point is not on the graph of the equation y=10+x
a. (0,10)
b. (3,13)
c. (8,2)
d. (5,15)
Please answer ASAP. Put the explanation too
Answers
Answer:
C. (8, 2)
Step-by-step explanation:
To find which point is not on the graph, find which set of coordinates makes the equation incorrect.
When plugged into the equation, the point (8, 2) makes it incorrect:
y = 10 + x
2 = 10 + 8
2 = 18
2 [tex]\neq[/tex] 18
The equation is incorrect because 2 is not equal to 18.
So, the point that is not on the graph is C. (8, 2)

Answers

Answer:
22/21
Step-by-step explanation:
Taking the derivative, we have ...
2x·dx +2y²·dx +4xy·dy +3·dy = 0
dx(2x +2y²) +dy(4xy+3) = 0
At the given point, this is ...
dx(2·2 +2·(-3)²) +dy(4·2·(-3) +3) = 0
22dx -21dy = 0
dy/dx = 22/21
The slope of the tangent at the point of interest is 22/21.

With the equation √400x¹⁰⁰
we need to take the square root away separately
√400 = √20*20 = 20
Then with x¹⁰⁰
√x¹⁰⁰ = √x⁵⁰*x⁵⁰ = x⁵⁰

Each of the following statements is true or false. Which statements are true?
A. A triangle where at least two angles are acute is called an acute triangle.
B. Some polygons are neither convex nor concave.
C. The sum of the interior angles of a concave pentagon is $540^{\circ}.$
D. The interior angles of a regular $1000$-gon are greater than the interior angles of a regular $100$-gon.
E. The exterior angles of a regular $1000$-gon are greater than the exterior angles of a regular $100$-gon.
Answers
9514 1404 393
Answer:
A. False
B. False
C. True
D. True
E. False
Step-by-step explanation:
A. False -- any triangle has at least two acute angles, whether it is acute, right, or obtuse.
B. False -- by definition, any polygon that is not convex is concave.
C. True -- the angle sum is the same regardless of whether the pentagon is convex or concave. (Provided it is a "simple" polygon, with no crossing sides.)
D. True -- the measure of the interior angle of a regular polygon increases as the number of sides increases. (see E)
E. False -- the exterior angles of a regular polygon are 360° divided by the number of sides. As the number of sides increases, the measure of each exterior angle decreases. (Interior angles are the supplement of exterior angles, so they increase as the number of sides increases.)
A 5 ounce bottle of juice cost $1.35 and an 8 ounce bottle of juice cost $2.16 a what is the unit cost per ounce of juice and b what is the better buy
Answers
Answers:
First bottle's unit cost = 27 cents per oz
Second bottle's unit cost = 27 cents per oz
Both have the same unit cost.
----------------------------------------
Work Shown:
unit cost = price/(number of ounces)
1st bottle unit cost = (1.35)/(5) = 0.27 dollars per oz = 27 cents per oz
2nd bottle unit cost = (2.16)/(8) = 0.27 dollars per oz = 27 cents per oz
Both lead to the same unit cost. Therefore, you can pick either option and it doesn't matter.

the mass of 2bags of beans and
3 bags of salt is 410kgs
if the mass of 3bags of beans and
2bags of salt is 390kg find the
mass of each item.
Answers
Answer:
70kg- weight of the bag of beans, 90 kg- weight of the bag of salt
Step-by-step explanation:
Suppose the mass of a bag of beans - x kg, the mass of a bag of salt - y kg
The mass 2 bags of beans 2x, The mass 3 bags of salt 3y
2x+3y= 410
The mass of 3 bags of beans 3x, for 2 bags of salt it is 2y
3x+2y=390
We have system of equations (the equations are simultaneous)
2x+3y=410
3x+2y=390
2x= 410-3y
x=205-1.5y
3* (205-1.5y)+2y=390
615-4.5y+2y=390
2.5y= 225
y=90- the mass of the bag of salt
x= 205 - 1.5*90= 205-135= 70- the mass of the bags of beans
