Graph the function need ASAP help
Is it a, b , c or d?
Answers
Answer:
D
Step-by-step explanation:
(the line is a / shape, so the slope is positive)
(the line crosses the y axis at (0,-2)
(using the above information, the equation is y=2x-2)
Answer:
y = 2x - 2
Step-by-step explanation:
Start with
y = mx + b
The graph shows the y-intercept -2.
We have y = mx - 2
slope = m = rise/run
The slope is rise of 2 and run of 1, so m = 2.
y = 2x - 2

Lines l and m are parallel. When they are cut by the two transversals below, a triangle is formed.
Parallel lines l and m are intersected by lines s and t. A triangle has angles 1, 2, 40 degrees. The exterior angle to angle 1 is 74 degrees.
What is Measure of angle 2
34 degrees
40 degrees
74 degrees
146 degrees
Answers
Answer:
<2 = 34degrees
Step-by-step explanation:
Find the diagram attached below:
First we need to get <1;
<1 + 74 = 180 (angle on a straight line)
<1 = 180 - 74
<1 = 106degrees
Also, <1 + <2 + 40 = 180 (sum of angle in a triangle)
106+<2 + 40 = 180
146 + <2 = 180
<2 = 180-146
<2 = 34degrees

34 its the right answer

Solve (x + 3)2 – 5 = 0 using the quadratic formula.
Answers
Answer:
Step-by-step explanation:
(x+3)² -5 =0 , use the formula (a+b) ² = a²+b²+2ab
x²+9 +6x -5 =0 , combine like terms
x²+6x +4 =0, use the quadratic formula x = (-b±√b²-4ac)/2a
x= (-6 ±√6²-4*1*4)/2*1
x= (-6 ± √36-16) /2
x= (-6±√20)/2
x=(-6 +2√5)/2 and x=( -6-2√5) /2, factor 2 in the numerator and simplify
x= -3 +√5 and x= -3 -√5

The mean number of travel days per year for salespeople employed by hardware distributors needs to be estimated with a 0.90 degree of confidence. For a small pilot study the mean was 150 days and the standard deviation was 14 days. If the population mean is estimated within two days, how many salespeople should be sampled
Answers
Answer:
133
Step-by-step explanation:
Given that :
Degree of confidence, α = 0.90 ; The Zcritical vlaue at α = 90% is 1.645
The margin of error, MOE = ±2
Standard deviation, s = 14
Using the relation :
n = (Zcritical * standard deviation) / MOE
n = ((1.645 * 14) / 2)²
n = (23.03 /2)²
n = 11.515²
n = 132.595
n = 133 samples

question 1…. help please
Answers
Answer: The number = 3 /4 or 4 / 3
Concept:
Here, we need to know the idea of a reciprocal.
Reciprocal is also called the multiplicative inverse. It is similar to turning the number upside down which is found by interchanging the numerator and denominator.
Number ⇒ Reciprocal = 1 / Number
Solve:
STEP ONE: Set up the equation
Let x = the number
Let 1 / x = the reciprocal
x + 1 / x = 25 / 12
STEP TWO: Multiply x on both sides
(x + 1 / x) · x = (25 / 12) · x
x² + 1 = 25x / 12
STEP THREE: Multiply 12 on both sides
(x² + 1) × 12 = (25x / 12) × 12
12x² + 12 = 25x
STEP FOUR: Subtract 25x on both sides
12x² + 12 - 25x = 25x - 25x
12x² - 25x + 12 = 0
STEP FIVE: Solve for the quadratic equation
(3x - 4) (4x - 3) = 0 ⇔ (Factorization of the equation)
(x - 4 / 3) (x - 3 / 4) = 0
x = 4 / 3 or x = 3 / 4
Hope this helps!! :)

A coin is tossed. If it shows heads, a marble is drawn from Box 1, which contains one white and two black marbles. If it lands tails, a marble is drawn from Box 2, which contains two white and two black marbles. Find P(black|coin fell tails).
Answers
Answer:
P(black|coin fell tails) = ¼
Step-by-step explanation:
Since a coin has a head and a tail, then probability of landing tail is;
P(tail) = ½
Now, if it falls tails, a marble is drawn from Box 2, which contains two white and two black marbles.
Thus, probability of getting a black marble is; 2/4 = ½
Thus;
P(black|coin fell tails) = ½ × ½ = ¼

For the transition matrix P = [0.8 2 0.2 2, 0.3 0.7], solve the equation SP = S to find the stationary matrix S and the limiting matrix Upper P overbar.
Answers
Answer:
Stationary matrix S = [ 0.6 0.4 ]
limiting matrix P = [tex]\left[\begin{array}{ccc}0.6&0.4\\0.6&0.4\\\end{array}\right][/tex]
Step-by-step explanation:
Transition matrix
[tex]p = \left[\begin{array}{ccc}0.8&0.2\\0.3&0.7\\\end{array}\right][/tex]
solving the equation SP = S ( using Markova chain with 2 states )
stationary matrix, S = [ a , 1 - a ]
given that SP = S
[ a , 1 - a ] * [tex]\left[\begin{array}{ccc}0.8&0.2\\0.3&0.7\\\end{array}\right][/tex] = [ a , 1 - a ]
= a*(0.8) + ( 1 - a ) ( 0.3 ) = a
∴ a = 0.6
hence; stationary matrix S = [ 0.6 0.4 ]
limiting matrix P = [tex]\left[\begin{array}{ccc}0.6&0.4\\0.6&0.4\\\end{array}\right][/tex]
