The value of the variable in the isosceles trapezoid is 24.
Calculation of the value of the variable:Since the measure of one angle should be 63 degrees
And, there is the equation 2x + 15 degrees
So for determining the value of x here we have to equate the equation
So,
2x + 15 = 63
2x = 63 - 15
2x = 48
x = 24
Therefore, The value of the variable in the isosceles trapezoid is 24.

Use the graph or table to find the equation that represents the relationship. PLLSSS HELPPPPP
Answers
The equation that is shown by the table is y = 3x - 5
How to use the graph or table to find the equation that represents the relationship?The given parameter is the complete table
From the table, we have the following points
(2, 1) and (1, -2)
Calculate the slope using
m = (y2 - y1)/(x2 - x1)
This gives
m = (-2 - 1)/(1 - 2)
Evaluate
m = 3
The linear equation is represented as
y = m(x - x1) + y1
So, we have
y = 3(x - 2) + 1
Open the bracket
y = 3x - 6 + 1
Evaluate the like terms
y = 3x - 5
Hence, the equation that is shown by the table is y = 3x - 5

Step-by-step explanation:
So we got the genious's theory that we all love/hate with
a^2 + b^2 = c^2
Now the longest side which in our case is also side (AC) is always gonna be C. So remember the longest side is always C. Since they give us the other 2 sides, we know those sides are (A) and (B) in the theorem.
So lets substitute.
34^2 + 41^2 = C^2
Simplify and It Equates to:
1156 + 1681 = c^2
2837 = c^2
Now Square Both Sides to cancel out that pesky ^2 on the (C) variable.
And you get 53.26 which rounds to 53.3 on your test. Good Luck!

Answers
Spinning a blue is unlikely

Distinguishing Likelihood From ProbabilityFundamentally crucial is the contrast between probability and likelihood: While likelihood is attached to hypotheses, probability is attached to potential outcomes. This first column's goal is to clarify this distinction.
The set of potential outcomes is complete and mutually exclusive. Let's say we ask a participant to forecast the results of ten coin flips. There are only 11 potential outcomes (0 to 10 correct predictions). One and only one of the potential outcomes will ever be the actual outcome. Therefore, the probability associated with the potential outcomes must add up to 1.
Contrary to outcomes, hypotheses are neither exhaustive nor mutually exclusive.

(2,5) and (10,3) What is the slope and the y-intercept
Answers
Answer:
slope is -1/4
y intercept is 11/2
Step-by-step explanation:
the slope is (3-5)/(10-2) = -2/8 = -1/4 (using the slope formula)
the y intercept we can set up an equation, y= mx + b
we already know m, which is -1/4 (the slope), and to find b, we could just plug in one of the points to get
5 = (-1/4)*2+b
solve the equation
b = 11/2
In a situation where the sample size was 28 while the population standard deviation was increased, what would be the impact on the confidence interval?
A) It would become narrower due to using the t distribution
B) It would widen with more values
C) It would become wider due to using the z distribution
D) It would become wider with more dispersion in values
Answers
Answer:
C; It would become wider due to using the z-distribution
Step-by-step explanation:
Mathematically, we go on to look at the formula for confidence interval calculations here
The formula involves multiplying z by the s
which is the z-value and the standard deviation
Increasing the standard deviation value means we are increasing the product of multiplying z and s
This means that we are getting a larger value for the multiplication
Thus, we now have a wider confidence interval value as a result of a larger product
So this means that the CI would become wider due to the usage of the z-distribution

Answers
The two real numbers with a sum of 2 and a product of −24 is -4 and 6.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.
Let x represent one number and y represent the other number. The sum of the two real numbers is two. Hence:
x + y = 2
y = 2 - x (1)
The product is -24, hence:
xy = -24
x(2 - x) = -24
2x - x² = - 24
x² - 2x - 24 = 0
x² - 6x + 4x - 24 = 0
x(x - 6) + 4(x - 6) = 0
(x + 4)(x - 6) = 0
x = -4 and x = 6
The two real numbers with a sum of 2 and a product of −24 is -4 and 6.

A middle school took all of its 6th grade students on a field trip to see a symphony at
a theater that has 4100 seats. The students filled 2296 of the seats in the theater.
What percentage of the seats in the theater were filled by the 6th graders on the trip?
Answers
The percentage of seats in the theatre that were filled by the 6th graders on the trip will be 56 %.
We are given that:
Total number of seats in the Symphony theatre = 4100 seats
The number of 6th grade students who filled the seats in the Symphony theatre = 2296
Now, we need to find the percentage of seats that were filled by the 6th grade students on the trip.
Percentage of 6th grade students = 2296 / 4100 × 100
Percentage of 6th grade students = 56 %
Therefore, we get that, the percentage of seats in the theatre that were filled by the 6th graders on the trip will be 56 %.

The perimeter of the triangle is 3x + 24 cm.
What is the perimeter of the triangle?A right triangle is a three-sided triangle that is made up of a length, base and the hypotenuse. The hypotenuse is the longest side of the right triangle The sum of the square of the two other sides of the triangle is equal to the square of the hypotenuse. The sum of angles in a right triangle is 180 degrees.
The perimeter of a right triangle is the sum of the length of the three sides of the triangle.
Perimeter = hypotenuse + base + height
Base = x Height = 8 + x Hypotenuse = 16 + xPerimeter = x + 8 + x + 16 + x

Divide $27,000 into 3 parts so that the second part is three times the first and the
third part is twice the second.
Answers
Answer:
the first part is $2700
the second part is $8100
the third part is $16200
Step-by-step explanation:
Call the first part a (a>= 0)
=> the second part 3a
=> the third part 2.3a = 6a
Because the total of three parts is 27000 so we have:
a + 3a + 10a = 27000
<=> 10a = 27000
<=> a = 2700 (satisfied)
so
the first part is: a = $2700
the second part is: 3a = 3 . 2700 = $8100
the third part is: 6a = 6 . 2700 = $16200
