Answer:
[tex]\huge\boxed{\sf <E = 40\°}[/tex]
Step-by-step explanation:
∠E = 1/2 (mCD - mAB)
Where mCD = 110° and mAB = 30°
∠E = 1/2 (110° - 30°)
∠E = 1/2 (80°)
∠E = 40°

find the value of k
9514 1404 393
Answer:
k = -2
Step-by-step explanation:
The determinant can be formed by subtracting up-diagonal products from down-diagonal products:
(x)(x+y)(y) +(y)(x)(x+y) +(x+y)(y)(x) -(x+y)^3 -x^3 -y^3
= 3xy(x+y) -(x^3 +3x^2y +3xy^2 +y^3) -x^3 -y^3
= -2(x^3 +y^3)
The value of k is -2.

A group of friends wants to go to the amusement park. They have no more than $325 to spend on parking and admission. Parking is $13.50, and tickets cost $21.25 per
person, including tax. Which inequality can be used to determine x, the maximum number of people who can go to the amusement park?
Answer:
14
Step-by-step explanation:
First you do 325 - 13.50 , then you just divide 311.50 by 21.25, and because you cant have .6 of a friend its 14 :)
can someone please help me find the value of p and q?
Answer:
[tex]q=31.7\\p=28.4[/tex]
Doing all calculations with 3 significant figures.
Step-by-step explanation:
First, we'll obtain the value of 'q', this by realizing how the two angles together form a right triangle with inner angles of 30, 60, 90.
Furthermore, the opposite side of the angle of 30 is 'q' and its adjacent is given as 55. Hence, we can solve for 'q' using tangent as follows:
[tex]tan(30)=\frac{q}{55} =.577[/tex]
We solve for 'q':
[tex]q=.577*55=31.7[/tex]
Now to solve for 'p', we first will calculate what '55-p' is equal to.
First, we realize '55-p' corresponds to the adjacent side to the angle of 50 inside the small right triangle (the one with inner angles of 50, 40, 90) and q (which we now know is 31.7) correspond to the opposite side. Hence, we again use tangent as follows:
[tex]tan(50)=\frac{q}{55-p} =\frac{31.7}{55-p} =1.19[/tex]
We solve for 'p':
[tex]1.19(55-p)=31.7\\65.5-1.19p=31.7\\1.19p=33.8\\p=\frac{33.8}{1.19}=28.4[/tex]

Joe has four birthday cakes to share between his 24 guests joe doesn't eat cake , but wants to cut them up so that each guest gets an equal piece what fraction is each piece of cake
The fraction of each piece of a cake is 1/6.
Given that, Joe has four birthday cakes to share with his 24 guests joe doesn't eat cake.
We need to find what fraction is each piece of cake.
What are fractions?A fraction represents a part of a whole or, more generally, any number of equal parts. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.
Now, 4 cakes are shared among 24 guests.
So, 24/4=6
Thus, each cake needs to divide into 6 slices.
Therefore, the fraction of each piece of a cake is 1/6.

Find m angle k please
Answer:
B. = 58°
Step-by-step explanation:
Sum of all angles in triangle = 180°
5x+30°+62°+x+52° = 180°
6x+144° = 180°
6x = 180°=144°
6x = 36°
x = 36°/6
x = 6°
∠K = x+52°
∠K = 6°+52°
∠K = 58°
The answer should be B
Answer:
Angle k = 6 +52 = 58
Step-by-step explanation:
The inside angles of a triangle equal 180 degrees. Therefore, 62° + (x+52°) + (5x + 30°) =180°

Step-by-step explanation:
Researchers make a one-sample zzz interval to estimate the proportion of adults who would say they learned something new in the past month. Previous studies have suggested that about 40\%40%40, percent would answer "yes" to this question. The researchers plan on using a confidence level of 95\%95%95, percent, and they want the margin of error to be no more than \pm 5\%±5%plus minus, 5, percent.
Answer:
369
Step-by-step explanation:
The researchers need a sample size of 385 to estimate the proportion of adults who would say they learned something new in the past month with a 95% confidence level and a margin of error of no more than ±5%.
What is a margin of error?The margin of error is the amount of error or uncertainty in a statistical estimate, usually an estimate of a population parameter based on a sample.
We have,
To create a one-sample z-interval, the following steps can be followed:
Determine the sample size (n) and the sample proportion p.
Since no sample size or proportion is given in the problem, we cannot proceed with this step.
Determine the level of confidence (C) for the interval. In this case, the researchers want a confidence level of 95%, so C = 0.95.
Find the critical value (z*) for the level of confidence.
This can be done using a standard normal distribution table or a calculator.
For a 95% confidence level, the critical value is 1.96.
Calculate the margin of error (ME) using the formula:
ME = z x √(p x (1 - p) / n)
Since the margin of error is given as no more than ±5%, we can set it equal to 0.05 and solve for the required sample size:
0.05 = 1.96 x √(0.4 x (1 - 0.4) / n)
Solving for n, we get:
n = (1.96 / 0.05)² x 0.4 x (1 - 0.4)
n ≈ 384.16
Since the sample size must be a whole number, we round up to the nearest integer and get n = 385.
Therefore,
The researchers need a sample size of 385 to estimate the proportion of adults who would say they learned something new in the past month with a 95% confidence level and a margin of error of no more than ±5%.
