find the measure of each angle indicated
a. 33
b. 36
c. 31
d. 136
Answer:
31
Step-by-step explanation:
Let the missing angle be x.
Sum of angles in a triangle is supplementary,
x + 20 + 129 = 180
x + 149 = 180
x = 180 - 149
x = 31
Answer:
31
Step-by-step explanation:
A triangle is 180 degrees.
129 + 20 = 149
180 - 49 = 33

In selecting one card from a deck of cards is obtaining a queen and obtaining a 2 mutually exclusive events?
A: Yes/True
B: No/False
Answer:
Mutually exclusive is a statistical term describing two or more events that cannot happen simultaneously. It is commonly used to describe a situation where the occurrence of one outcome supersedes the other.
Since in this question, we have selected one card from a deck, and is obtaining a 2 and a queen.
I think the answer for this would be No/False but if i'm wrong, tell me!

Answer:
Your answer is B
Step-by-step explanation:
If you use the division you technically can't use the distributive property, so it could be A. But if you had to use it; I would say the best way to do so it to multiply everything by 1.

Help!!!!! find the value of x.
Answer:
x = 48
Step-by-step explanation:
The two angles shown in the diagram are supplementary and add to 180° because they form a straight line. We can set up an equation:
x - 12 + 3x = 180
4x - 12 = 180
4x = 192
x = 48
Answer:
[tex]x=42[/tex] ✔︎
Step-by-step explanation:
∠1 + ∠2=1803x+x-12=1804x-12=1804x=180-124x=168x=42°∠1= 3x=3×42=126°
∠2=x-12=42-12= 30°

A tennis court has a length of (5x+7) and a width of (3x-3).
What is the area of the tennis court?
What is the median please help please help
Answer:
54.5
Step-by-step explanation:
To find the median, first we have to put the numbers in ascending/increasing order.
43, 60, 50, 36, 58, 50, 73, 59, 69, 51 is your set
36, 43, 50, 50, 51, 58, 59, 60, 69, 73 is your set in order.
The median is the middle number of the data set. Your set has an even number of entries, so we have to average the 2 middle numbers, which are 51 and 58.
36, 43, 50, 50, 51, 58, 59, 60, 69, 73
51 + 58 = 109
109/2 = 54.5

A video store charges $5 per game rental plus $12 to rent the game system. Write an expression for renting the game system and a number of games.
Answer:
12 + 5X = Y
Step-by-step explanation:
Given that a video store charges $ 5 per game rental plus $ 12 to rent the game system, to write an expression for renting the game system and a number of games the following logical reasoning must be performed:
5 = variable not fixed, depends on the number of games
12 = fixed variable
X = number of games
Y = total value
12 + 5X = Y
Thus, if 5 video games were rented, the equation would operate as follows:
12 + 5x5 = Y
12 + 25 = Y
37 = Y
What is the rule of 72?
Answer:
Brainiest please
Step-by-step explanation:
In finance, the rule of 72, the rule of 70 and the rule of 69.3 are methods for estimating an investment's doubling time. The rule number (e.g., 72) is divided by the interest percentage per period (usually years) to obtain the approximate number of periods required for doubling. Although scientific calculators and spreadsheet programs have functions to find the accurate doubling time, the rules are useful for mental calculations and when only a basic calculator is available.
A student measures the volume of a rubber stopper and finds that it is 36ml. The
teacher also measures the stopper and obtains a value of 40 ml. Other students
measure the stopper and it is decided to use 38 ml as the standard value for the
volume of the stopper. What was the student's percentage error? The teachers
error?

A recent study revealed that the average weight of babies born in the United States is normally distributed with a mean of 7.5 pounds. This number is lower than recent years and so researchers are interested in determining what factors are associated with lower birth weights. One researcher decides to look at the age of the mother to determine if younger mothers have babies that are significantly heavier or lighter than average. To study this the researcher collects data from 87 babies who were born to mothers between the ages of 16 and 18. Only one baby was measured per mother. Twins and other multiple births were excluded. The average weight for these babies was 7.3 pounds with a standard deviation of .6 pounds.
Which of the following statements is relevant to the assumption of Normality?
a. the standard deviation for young mothers is not expected to be different than the standard deviation in the population
b. only one baby was measured per mother
c. weights of babies are normally distributed in the population
d. the study used a sample that is different than the comparison population and measured weight on a ratio scale
Answer:
a. the standard deviation for young mothers is not expected to be different than the standard deviation in the population
Step-by-step explanation:
The population mean = μ= 7.5
Sample mean = x`= 7.3
Sample standard deviation= s= 0.6
Sample size = 87
Assuming normality we perform z test
z= x`-u/s/√n
z= 7.3-7.5/0.6/√87
z= -3.11
The critical region for 0.05 for two tailed test is z>+1.96 and Z<-1.96
Since the calculated z= -3.11 falls in the critical region Z<-1.96 we conclude that birth rate is lower in the young mothers.
a. the standard deviation for young mothers is not expected to be different than the standard deviation in the population
Only choice a is correct because when n > 30 the population standard deviation and the sample standard deviation are assumed to be normal
Choice b cannot be the correct option because it is already inferred that only one baby was measured per mother.
Choice C cannot be also the best choice because it is already assumed.
Choice d is totally incorrect.
Which trig ratio? Can you solve this??
Step-by-step explanation:
There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant and cotangent. These six trigonometric ratios are abbreviated as sin, cos, tan, csc, sec, cot. These are referred to as ratios since they can be expressed in terms of the sides of a right-angled triangle for a specific angle θ.

I'm still doing the rest but number 1 is D
What is coordinates of point C?
Answer:
(3,6)
Step-by-step explanation:
Using the midpoint segment formula
M(X, Y) = [(ax1+bx2/2, ay1+by2/2)]
Given (-2 -6) and (4,6) divided in the ratio 1:5
X = 1(-2) + 5(4)/1+5
X = -2+20/6
X = 18/6
X = 3
Similarly
Y = 1(-6)+ 5(6)/1+5
Y = -6+30/6
Y = 24/6
Y = 4
Hence the required coordinate of C is (3,6)

URGENT QUESTION.
The graph represents all solutions to an inequality
Please tell me the answer to this question. It is urgent...
Answer:
The answer is D. -9 and -3
Step-by-step explanation:
since the graph starts at 1 and goes backwards, it cant be 1. so that rules out A. and B. then it requires the numbers to be negative because if they are a whole number over 1, they don´t fit the inequality. I hope this helps :))
