b+53+245=360
b+298=360
b=360-298
b=62
Answer:
62
Step-by-step explanation:
360 degrees is the total … You get the point.
360 degrees - 245 degrees
= 115 degrees
Now, we go onto the angle
The total measure of the angle is 115 degrees
The angle has been split into two angles. On of the angles measure is 53 degrees. To find the measure of the other angle, you have to subtract the measure of the angle that was given 53 degrees) by the total measure (115 degrees):
115 degrees - 53 degrees
= 62 degrees

Refer to the table above. Determine the percent of all voters that did not vote Republican or Democrat but voted "other" instead. Round your answer to the nearest tenth of a percent.
Answer:
9.9%
Step-by-step explanation:
Well, you would just divide the "other" category and the "total" category and then move the decimal over 2 spaces, because you need to multiply by 100 to turn your answer into a percent, so:
Then once you multiply by 100, or move the decimal to the left 2 spaces, it becomes:
9.9%, which could be rounded to 10% or 9%.

1. In ABC, A=45 degrees, B=75 degrees, and BC=12. What is the length of AB?
We know that sum of the interior angles of any triangle equal 180° :
So :
A + B + C = 180°
45° + 75° + C = 180°
120° + C = 180°
Both sides minus ( 120°) :
C = 180° - 120°
C = 60°
_________________________________
According to the theorem of sinuses :
[tex] \frac{AB}{ \sin(C) } = \frac{BC}{ \sin(A) } \\ [/tex]
[tex] \frac{AB}{ \sin(60) } = \frac{12}{ \sin(45) } \\ [/tex]
[tex] \frac{AB}{ \frac{ \sqrt{3} }{2} } = \frac{12}{ \frac{ \sqrt{2} }{2} } \\ [/tex]
[tex]Multiply \: both \: sides \: by \: \frac{ \sqrt{3} }{2} [/tex]
[tex] AB = \frac{24}{ \sqrt{2} } \times \frac{ \sqrt{3} }{2} \\ [/tex]
[tex]AB = \frac{12 \sqrt{3} }{ \sqrt{2} } \\ [/tex]
[tex]AB = \frac{2 \times 6 \sqrt{3} }{ \sqrt{2} } \\ [/tex]

MP bisects ∠BMS. If m∠BMP = 2x + 9 and m∠BMS = 7x – 3, find the value of m∠PMS
Answer:
Step-by-step explanation:
If MP bisects ∠BMS, then the line MP divides <BMS equally;
The adition postulate if therefore true;
<BMP +< PMS = <BMS and <BMP = < PMS
The equation becomes;
<BMP +< BMP= <BMS
2 <BMP = <BMS
2(2x+9) = 7x - 3
4x+18 = 7x-3
collect like terms
4x-7x = -3-18
-3x = -21
x = 21/3
x = 7
Since <BMP = < PMS 2x+9
< PMS = 2(7)+9
< PMS = 14+9
< PMS = 23
Hence the value of < PMS is 23

The Martians are trying to destroy Earth by launching an anti-matter rocket (it will be disastrous it will hit earth). In response, Earth launches 500 missiles towards the rocket. Each missile will hit the rocket with probability 0.01, independently of other missiles. What is the probability that Earth will be saved, if at least 3 missiles must hit the rocket in order to destroy it before it hits Earth
Answer:
The probability the earth is saved is [tex]P(X > 3) = 0.8753 [/tex]
Step-by-step explanation:
From the question we are told that
The number of missiles lunched by earth is n = 500
The probability that each missile will hit the rocket is p(x) = 0.01
Generally the expected number of missiles that will hit the rocket is
[tex] \lambda = n * p(x)[/tex]
[tex]\lambda = 500 * 0.01 [/tex]
[tex]\lambda = 5[/tex]
Gnerally the probability that Earth will be saved is mathematically represented as
[tex]P(X > 3) = 1 - P(X \le 2)[/tex]
=> [tex]P(X > 3) = 1 - P( X = 0 ) + P(X =1 ) + P( X = 2) [/tex]
Gnerally the probability distribution function of a Poisson distribution is
[tex]P(K) = \frac{e^{- \lambda t } * (\lambda * t)^k}{k!}[/tex]
Here t = 1
Hence
[tex]P( X = 0 ) = \frac{e^{-5} * 5^0 }{0!}[/tex]
[tex]P(X =1 ) =\frac{e^{-5} * 5^1 }{1!}[/tex]
[tex]P( X = 2) = \frac{e^{-5} * 5^2 }{2!}[/tex]
[tex]P(X > 3) = 1 - [ \frac{e^{-5} * 5^0 }{0!} + \frac{e^{-5} * 5^1 }{1!} + \frac{e^{-5} * 5^2 }{2!}][/tex]
[tex]P(X > 3)= 1 - [ \frac{0.00673 }{1} + \frac{0.033689}{1} + \frac{0.168449 }{2}][/tex]
[tex]P(X > 3) = 0.8753 [/tex]
1. Contaminated water is subjected to a cleaning process. The concentration of the
pollutants is initially 5 mg per liter of water. If the cleaning process can reduce the
pollutant by 10% each hour, define a function that can represent the concentration
of pollutants in the water in terms of the number of hours that the cleaning process
has taken place.
Answer:
The concentration of pollutants in the water can be defined as the quotient between the mass of pollutants and the total mass of water.
Assuming that 1L of water weighs 1000 grams, we know that:
Mass of pollutants = 5mg = 0.005g.
Initial concentration = 0.005g/1000g = 0.000005
If we multiply this by 100%, we get the percentage:
0.000005*100% = 0.0005%
Now, the mass of pollutants decreases by 10% each hour.
So if initially, we have 5mg
After one hour, we will have: 5mg - 0.1*5mg = 5mg*(0.9).
After another hour, we will have: 5mg*(0.9) - 0.1*5mg*0.9 = 5mg*(0.9)^2.
And so on, then after n hours, the mass of pollutants will be:
M(n) = 5mg*(0.9)^n
Or we can write this in grams as:
M(n) = 0.005g*(0.9)^n
Then the concentration as a function of time in hours will be:
C(n) = M(n)/1000g = (0.005g/1000g)*(0.9)^n
Notice that the thing between the parentheses is the initial concentration, then if we write this in percentage form:
c(n) = 100%*(0.005g/1000g)*(0.9)^n = 0.0005%*(0.9)
The function that represents the concentration of polution in the water as a function of hours is:
c(n) = 0.0005%*(0.9)

Sports. The path of a particular punt follows the quadratic function where is the height of the ball in yards and corresponds to the horizontal distance in yards. Assume corresponds to midfield (the yard line). For example, corresponds to the punter's own yard line, whereas corresponds to the other team's yard line. a. Find the maximum height the ball achieves. b. Find the horizontal distance the ball covers. Assume the height is zero when the ball is kicked and when the ball is caught.
The question is incomplete. The full question is below.
The path of a particular punt follows the quadratic function
[tex]h(x)=\frac{-1}{8}(x-25)^{2}+50[/tex]
where h(x) is the height of the ball in yards and x corresponds to the horizontal distance in yards. Assume x=0 corresponds to midfield (the 50 yards line). For example, x=20 corresponds to the punter's own 30 yard line, whereas corresponds to the other team's 30 yard line.
a. Find the maximum height the ball achieves.
b. Find the horizontal distance the ball covers. Assume the height is zero when the ball is kicked and when the ball is caught.
Answer: a. Maximum height = 50
b. Horizontal distance = 40
Step-by-step explanation: A quadratic function has its maximum or minimum point on its vertex.
When the function is negative, function has a maximum point.
The quadratic function h(x) is written in vertex form, meaning the coordinate of vertex is explicit in the function.
General vertex form: [tex]f(x)=A(x-h)^{2}+k[/tex]
A is vertical scaling parameter
(h,k) are the coordinates of vertex
So, the quadratic function for the height for the ball:
[tex]h(x)=\frac{-1}{8}(x-25)^{2}+50[/tex]
shows its vertex:
(h,k) = (25,50)
a. The maximum height the ball achieves the maximum value corresponds to the y-axis, which means, maximum height is 50 yards.
b. Horizontal distance is when h(x)=0, so:
[tex]\frac{-1}{8}(x-25)^{2}+50=0[/tex]
[tex]\frac{-1}{8}(x-25)^{2}=-50[/tex]
[tex](x-25)^{2}=400[/tex]
[tex]x^{2}-50x+625=400[/tex]
[tex]x^{2}-50x+225=0[/tex]
Solving quadratic equation:
[tex]x_{1}=\frac{50+\sqrt{1600} }{2}[/tex] = 45
[tex]x_{2}=\frac{50-\sqrt{1600} }{2}[/tex] = 5
When ball is kicked, it is in position 5. When is caught, is position 45. So, distance the balls covers is 40 yards.

A municipal bond service has three rating categories (A, B, and C). Suppose that in the past year, of the municipal bonds issued throughout the United States, 70% were rated A, 20% were rated B, and 10% were rated C. Of the municipal bonds rated A, 50% were issued by cities, 40% by suburbs, and 10% by rural areas. Of the municipal bonds issued B, 60% were issued by cities, 20% by suburbs, and 20% by rural areas. Of the municipal bonds rated C, 90% were issued by cities, 5% by suburbs, and 5% by rural areas. a. If a new municipal bond is to be issued by a city, what is the probability that it will receive an A rating? b. What proportion of municipal bonds are issued by cities? c. What proportion of municipal bonds are issued by suburbs?
Answer:
(a) The probability that the new municipal bond issued will receive an A rating given that it was issued by a city is 0.196.
(b) Thus, the probability of municipal bonds issued by suburbs is 0.325.
Step-by-step explanation:
The data provided is as follows:
P (A) = 0.70
P (B) = 0.20
P (C) = 0.10
P (c | A) = 0.50
P (s | A) = 0.40
P (r | A) = 0.10
P (c | B) = 0.60
P (s | B) = 0.20
P (r | B) = 0.20
P (c | C) = 0.90
P (s | C) = 0.05
P (r | C) = 0.05
(a)
The Bayes' theorem states that the conditional probability of an event Y[tex]_{i}[/tex] given that another event X has already occurred is:
[tex]P(Y|X)=\frac{P(X|Y)P(Y)}{\sum\limits_{i} {P(X|Y_{i})P(Y_{i})}}[/tex]
Compute the probability that the new municipal bond issued will receive an A rating given that it was issued by a city as follows:
[tex]P(A|c)=\frac{P(c|A)P(A)}{P(c|A)P(A)+P(c|B)P(B)+P(c|C)P(C)}[/tex]
[tex]=\frac{(0.50\times 0.70)}{(0.50\times 0.70)+(0.60\times 0.20)+(0.10\times 0.90)}\\\\=\frac{0.35}{0.56}\\\\=0.196[/tex]
Thus, the probability that the new municipal bond issued will receive an A rating given that it was issued by a city is 0.196.
(b)
The law of total probability states that:
[tex]P(X)=\sum\limits_{i} {P(X|Y_{i})}[/tex]
Compute the probability of municipal bonds issued by suburbs as follows:
[tex]P(s)=P(s|A)P(A)+P(s|B)P(B)+P(s|C)P(C)[/tex]
[tex]=(0.40\times 0.70)+(0.20\times 0.20)+(0.10\times 0.05)\\\\=0.28+0.04+0.005\\\\=0.325[/tex]
Thus, the probability of municipal bonds issued by suburbs is 0.325.
What is the Reciprocal of 10/3
Answer: 3/10
Step-by-step explanation:
The reciprocal is the fraction/ number flipped
x-intercept=3, y-intercept=-4 put into slope intercept form
y = mx + c
y intercept= (0,-4) , x intercept = (3,0)
m = (y2-y1)/(x2-x1)
m = (0-(-4))/(3-0)
m = 4/3
0 = (4/3)(3)+ c
c = -4

the diagonals of a rhombus are in the ratio 3 :4 if the longer diagonals is of 12 cm then find the area of rhombus.
Answer:
Area= 54 cm^2
Step-by-step explanation:
Recall that a rhombus is given by the product of its two diagonals (d1 and d2) divided by 2.
Area = d1 * d2 / 2
So in our case, the longer diagonal is 12 cm long, and the shortest one should be in the ratio 3:4, therefore:
3 /4 = d2 / d1
3 / 4 = d2 / 12
d2 = 3 * 12 /4
d2 = 3 * 3
d2 = 9 cm
Then we can now calculate the Area of the rhombus as;
Area = d1 * d2 / 2 = 12 * 9 / 2 = 54 cm^2

When you're asked to find f(n), locate n on the x-axis, then move up or down along the grid line until you meet the curve. Then move horizontally to the f(x) axis and read the value from that.
This process is illustrated in the attachment.
