? + 31° + 94° = 180°
? + 125° = 180°
? = 180° - 125°
? = 55°
Answer: 52°
Step-by-step explanation:
Angles in a triangle always add up to 180°.
So to work out what the missing angle is, you would have to add 34 and 94 together.
34+94=128
Then you would have to take 128 away from 180.
180-128=52°
Hope this helps :)

if there are only 2 of a particular stamp remaining out of 5000 originally printed, what percent remains today?
Answers
Answer:
0.04%
Step-by-step explanation:
To find a percentage, we want to create a ratio of a portion by the total.
Our portion is 2.
Our total is 5000.
Let's create the ratio by dividing the numbers.
2/5000
Divide.
= 0.0004
Multiply this by 100 to find the percentage.
0.04%
This is your answer.
Check your answer by plugging it into a percentage equation.
0.04/100 of 5000 = 2
0.0004 • 50000 = 2
2 = 2
Your answer is correct.
Hope this helps!
6) The Delphi method used for forecasting: A) uses a single measure that weights multiple indicators and provides a measure of overall expectation. B) obtains forecasts through a comparative analysis with a previous situation. C) uses a panel of experts, whose identities are typically kept confidential from one another, to respond to a sequence of questionnaires. D) uses measures that are believed to influence the behavior of a variable that the researcher wishes to forecast.
Answers
Answer:
C) uses a panel of experts, whose identities are typically kept confidential from one another, to respond to a sequence of questionnaires.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Opportunity or convenience sampling.
The Delphi method is a structured communication framework or technique that is typically used as an interactive forecasting method to arrive at a group decision or opinion by relying on the feedback from a panel of experts. The individual opinions of the panel of experts are modified to ensure anonymity and are mainly an unbiased exchange of ideas, so as to produce a convergence of opinions.
Hence, the Delphi method used for forecasting uses a panel of experts, whose identities are typically kept confidential from one another, to respond to a sequence of questionnaires.

A small liberal arts college in the Northeast has 350freshmen. One hundred five of the freshmen are female. Suppose sixty freshmen are randomly selected (without replacement).Step 2 of 2:Find the standard deviation of the number of females in the sample. Round your answer to two decimal places, if necessary.
Answers
Answer:
The standard deviation of the number of females in the sample is 3.21.
Step-by-step explanation:
For each freshmen, there are only two possible outcomes. Either it is a female, or it is not. Sixty freshmen are randomly selected (without replacement). This means that the hypergeometric distribution is used to solve this question.
Standard deviation of the hypergeometric distribution:
We have that:
N is the population size.
n is the sample size.
s is the number of successes in the sample.
The standard deviation is given by:
[tex]\sigma = \sqrt{n(\frac{s}{N})(1 - \frac{s}{N})(\frac{N - n}{N-1})}[/tex]
A small liberal arts college in the Northeast has 350freshmen.
This means that [tex]N = 350[/tex]
One hundred five of the freshmen are female.
This means that [tex]s = 105[/tex]
Suppose sixty freshmen are randomly selected
This means that [tex]n = 60[/tex]
Find the standard deviation of the number of females in the sample.
[tex]\sigma = \sqrt{60(\frac{105}{350})(1 - \frac{105}{350})(\frac{350 - 60}{350 -1})} = 3.21[/tex]
The standard deviation of the number of females in the sample is 3.21.

Solve for x.
4x - 6 = 30
Answers
Answer:
x = 9
Step-by-step explanation:
Move all terms that don't contain x to the right side and solve.
The solution to the equation 4x - 6 = 30 is x = 9.
What is the solution to the equation?Given the equation in the question:
4x - 6 = 30
To solve the equation 4x - 6 = 30, first, isolate the term with the variable:
4x - 6 = 30
Add 6 to both sides of the equation to isolate the term with the variable:
4x - 6 + 6 = 30 + 6
Add -6 and 6
4x + 0 = 30 + 6
4x = 30 + 6
Add 30 and 6
4x = 36
Divide both sides of the equation by 4 to solve for x:
(4x)/4 = 36/4
x = 36/4
x = 9
Therefore, the value of x is 9.

6+2/3=-20+x
6=-20+1/3x
x=78
Answer:
x=6
Step-by-step explanation:
Distribute.
2/3 * 9 = 6
2/3 * x = 2/3x
Distribute other side.
-5*4 = -20
-5 * -x = 5x
Rewrite.
6 + 2/3x = -20 + 5x
Subtract 5x from both sides.
-13/3x + 6 = -20
Subtract 6 from both sides.
-13/3x = -26
Multiply -3/13 to both sides.

Step-by-step explanation:
Triangle is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
The area of the triangle.
= 1/2 x base x height
The area of the triangle is 105760 cm².
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
In ΔVWX.
w = 680 cm
∠X=80°
∠V=32°
This means,
∠W + ∠X + ∠V = 180
∠W = 180 - 112
∠W = 68°
This means,
68° = 680
1° = 10
Now,
∠X=80°
x = 800 cm
∠V=32°
v = 320 cm
Now,
V
/ | \
(x) / | \ (w)
/ | \
W M X
(v)
680² = VM² + (320/2)²
462400 = VM² + 25600
VM² = 436800
VM = 661 cm
Thus,
The area of the triangle.
= 1/2 x base x height
= 1/2 x 320 x 661
= 160 x 661
= 105760 cm²
