1. The midsegment of a trapezoid is half the sum of the bases.
true or false ?
Answers
Answer:
TRUE
Step-by-step explanation:
TRUE
Therefore, the given statement "The midsegment of a trapezoid is half the sum of the bases" is True.
What is a trapezium?A trapezium is a quadrilateral with two parallel sides. It has two non-parallel sides that are called the legs of the trapezium, and the other two sides are called the bases.
The midsegment of a trapezoid is a line segment that connects the midpoints of the two non-parallel sides of the trapezoid. Since the midsegment connects the midpoints of the two non-parallel sides, it will always have the same length as half the sum of the two bases.
Therefore, the given statement is True.

Tell whether the angles are complementary or supplementary. Then find the value of $x$ . A ray intersects two other rays forming a right angle. The angles formed after the intersection is x degrees and left parenthesis x minus 20 right parenthesis degrees.
Answers
The measure of the value of x is 55°.
We have,
Complementary angles are two angles that add up to 90 degrees.
Supplementary angles are two angles that add up to 180 degrees.
Now,
The ray intersects two other rays forming a right angle.
This means,
It is a complementary angle.
i.e
x + (x - 20) = 90
x + x - 20 = 90
2x = 90 + 20
2x = 110
x = 55°
Thus,
The measure of the value of x is 55°.

The sum of David's weight and Mike's weight is 180 pounds. If you subtract David's weight from Mike's weight, you get half of Mike's weight. How much does Mike weigh?
Answers
Answer: 120 Pounds
Step-by-step explanation:
Given
The Sum of David and mike weight is 180 pounds
Suppose the weight of David is x and the weight of mike is y
So, [tex]x+y=180[/tex]
Also, subtracting David's weight from Mike's weight, we get half of Mike's weight
[tex]\Rightarrow y-x=\dfrac{y}{2}\\\Rightarrow 2x=y[/tex]
Put the value of x in the above equation, we get
[tex]\Rightarrow 1.5y=180\\\Rightarrow y=120\ pounds[/tex]
Thus, mike Weighs 120 Pounds

A polynomial of degree 3 is multiplied by a polynomial with of degree 5
What is the degree of the product?
A. 2
B.8
C.15
D. The degree could vary based on the polynomials
Answers
Answer:
B.8
Step-by-step explanation:
The degree of a polynomial refers to the term with the highest exponent. Thus the highest exponent in a degree 3 polynomial is x3; for a degree 5 polynomial, it's x5. When you multiply
x3*x5 = x3+5 = x8.
So the product of a degree 3 polynomial and a degree 5 polynomial is a degree 8 polynomial.
Your leading term will result from the 3-degree term of the first polynomial, and the 5-degree term of the second. So you'll have something like ax3 * bx5. That will result in x3*x5=x8, so your product will have degree 8.

A scientist selected a random sample of seven varieties of peach ice cream to investigate the relationship between the density, in pounds per cubic inch, of the varieties of ice cream and the percent concentration of peaches in the ice cream. Assuming all conditions for inference are met, which of the following significance tests should be used to investigate whether there is convincing evidence at the 0.05 level of significance that a greater percent of peaches in the ice cream is associated with an increase in the density of the ice cream?
A. A two-sample t-test for a difference between means
B. A chi-square test of independence
C. A linear regression t-test for slope
D. A two-sample z-test for a difference between proportions
E. A matched pairs t-test for a mean difference
Answers
Answer:
The significance test that would be used to investigate whether there is convincing evidence at 0.05 level of significance that a greater percent of peaches in the ice cream is associated with an increase in the density of the ice cream is option C;
C. A linear regression t-test for slope
Step-by-step explanation:
The linear regression t-test for slope is a test for determining the existence of a statistically significant linear relationship between two variables, a independent variable, X and an dependent variable Y in the following form;
Y = B₀ + B₁·X
The test is used to test the regression line slope where we have;
B₀ = The constant
B₁ = The slope also known as the regression coefficient
The given information tested in the question is if an increase in the peaches in the ice cream is associated with an increase in the density of the ice cream, therefore, the test to investigate the relationship between the rate of both variables is the linear regression t-test for slope.
Therefore, we have
Y = B₀ + B₁·X
Where;
X = The percentage of peaches in the ice cream
Y = The density of the ice cream
