SOMEONE PLEASE HELP ASAP!!!
Answer:
Step-by-step explanation:
Recall that (a-b)(a+b) = a^2 - b^2
So,
(x-2i)(x+2i) = x^2 - (2i)^2 = x^2+4
(x+i-i)(x+1+i) = (x+1)^2 + 1 = x^2 + 2x + 2
(x-2+2i)(x-2-2i) = (x-2)^2 + 4 = x^2 - 4x + 8
Selecting a State Choose one of the 50 states at
random.
a. What is the probability that it begins with M?
b. What is the probability that it doesn't begin with a
vowel?
Answer:
PART ONE- 8/50 PART 2-38/50
Step-by-step explanation:
First of all, we know that there are 50 states. Lets see how many states begins with M first.
Maine (27 C, 5 P)
Maryland (28 C, 5 P)
Massachusetts (29 C, 4 P)
Michigan (28 C, 4 P)
Minnesota (28 C, 2 P)
Mississippi (27 C, 6 P)
Missouri (25 C, 3 P)
Montana (27 C, 6 P)
There are 8 states which means that the probabilty is 8/50 which simplifies to 4/25
We know that 12 states begins with a vowel. 50-12 is 38/50
The probability that it begins with M is 0.16 and the probability that it doesn't begin with a vowel is 0.76
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur.
Given that, Selecting a State, Choose one of the 50 states at random.
We know that, P(A) = n(A)/n(S)
where, P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.
a) There are 8 states which begins with M, that means the probability = 8/50 = 4/25 = 0.16
b) We know that 12 states begins with a vowel,
Therefore, the probability that it doesn't begin with a vowel = 1 - 12/50 = 38/50 = 0.76
Hence, The probability that it begins with M is 0.16 and the probability that it doesn't begin with a vowel is 0.76

que es suma y resta de fracciones homogeneas
Answer:
responder
Step-by-step explanation:
Para sumar y restar fracciones, sus denominadores deben ser iguales. Por tanto, sumar o restar fracciones homogéneas es más fácil, dado que ya tienen el mismo denominador.
Answer:
Recuerda que cuando se suman fracciones homogéneas se hace lo mismo que cuando se suman objetos del mismo tipo. Por ejemplo, la suma tres décimos más dos décimos da como resultado cinco décimos: , por la misma razón que sumar tres vacas más dos vacas da como resultado cinco vacas.

What is the slope intercept form for this?
Slope= -1 Y intercept= 8
Answer:
y= -x+8
Step-by-step explanation:
y=m+b Replaced M with -1 which will be -x.
y= -x+b Then replace the b with 8.
y= -x+8
You do -x because its the same as -1.
Answer:
y = -x + 8
Step-by-step explanation:
Hi there!
We are given that the slope of a line is -1 and the y intercept of that same line is 8
We want to find the equation in slope-intercept form
Slope-intercept form can be written as y=mx+b, where m is the slope and b is the y intercept
As we are already given the values of the slope and the y intercept, we can simply substitute these values into the formula to find the equation.
First, substitute -1 as m in the equation:
y=-x+b (when 1 is the coefficient, you don't need to write '1' in front of a variable; when -1 is the coefficient, putting only a - sign will suffice)
Now substitute 8 as b in the equation
y = -x + 8
Hope this helps!

A deal is a deal, so here is a good one, let's see who gets it right I had $5.00. My mom gives me $10.00, My dad gave me $30.00. My aunt and uncle give $100.00. I had another $5.00. How much money did I have?
Answer:150.00$
Step-by-step explanation:
The total amount that the person will have is $150.00
Amount that the person had = $5.00 + $5.00 = $10.00Amount given by mum = $10.00Amount given by dad = $30.00Amount given by aunt and uncle = $100.00The total amount that the person had will be the addition of all the amount that he already had and those that he was given. This will be calculated thus:
$10.00 + $10.00 + $30.00 + $100.00 = $150.00
Therefore, the total amount that the person will have is $150.00

Answer:
x=2
Step-by-step explanation:
hope it helps
please mark as Brainliest
Answer:
x = 2
Step-by-step explanation:
For me it's easier to work with decimals than fractions, so I converted 3/4 to .75
.75(x + 18) = 15
.75x + 13.5 = 15
That was just distributing the .75 but here is where it gets a bit confusing.
.75x + 13.5 = 15
-13.5 -13.5
.75x = 1.5
Divide both sides by .75 to isolate the variable.
x = 2

the following angles. Explain your reasoning.
F

В.
38 A.
1. BCD
2. ZECF
3. ZDCF
Answer/Step-by-step explanation:
1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°
2. m<ECF = m<BCD (corresponding angles)
m<ECF = 38° (substitution)
3. m<DCF + m<ECF = 180° (linear pair)
m<DCF + 38° = 180° (substitution)
m<DCF = 180° - 38° (Subtraction property of equality)
m<DCF = 142°

Find the value of a. Then find the angle measures of the quadrilateral.
Answer:
a = 60
Step-by-step explanation:
Since it is a quadrilateral, the sum of interior angles is equal to 360°. Now you have to create an equation to solve this question. To create an equation, you have to add all the interior angles to 360°.
The equation would be 2a°+a°+a°+2a° = 360°.
Then you would simplify it to 6a° = 360.
You would divide 6 on both sides to get to a° = 60.
Therefore, the value of a is 60.
