1. The midsegment of a trapezoid is half the sum of the bases.
true or false ?
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.

Find the perimeter
~~~~~~~~~~~~~~~~~~~
Answer:
P = 2x^3 + 14x^2 + 8x + 6
Step-by-step explanation:
The perimeter of this figure is P = 2W + 2L, or, in this specific case,
P = 2(7x^2 + 4x + 3) + 2(x^3), which, when expanded, comes out to:
P = 14x^2 + 8x + 6 + 2x^3, or, in standard form:
P = 2x^3 + 14x^2 + 8x + 6

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
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.
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.
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°.

In 1947, milk cost $0.75 per gallon and bananas cost $0.15 per pound. Donna bought two gallons of milk and some bananas for a total of $2.25 in 1947. How many pounds of bananas did she buy?
Answer:
Answer is 5 pounds of bananas
Step-by-step explanation:
Required milk:
Milk= 2 gallons
Milk cost per gallon=$0.75
so,
2*0.75
$ 1.5
total amount =$2.25
to calculate bananas
$2.25-$1.5=$0.75
per pound cost of bananas =$0.15
$0.75/$0.15
5 pounds of bananas
Dona bought 5 pounds of banana and 2 gallons of milk for a total of $2.25.
What are linear and non-linear functions?A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.
Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.
An example of a non-linear function is a quadratic function.
Given, In 1947, milk cost $0.75 per gallon and bananas cost $0.15 per pound.
Let,The cost of one gallon of milk is 'x' dollars and the cost of one pound of banana is 'y' dollars.
Also given Donna bought two gallons of milk and some bananas for a total of $2.25.
Therefore, 2(0.75) + 0.15y = 2.25.
0.15y = 2.25 - 1.5.
0.15y = 0.75.
y = 0.75/0.15.
y = 5.
So, Dona bought 5 pounds of bananas.

Let f(x)=x^2+2 and g(x)=1-3x Find each function value. f(g(-4))
Answer:
171
Step-by-step explanation:
First you plug -4 into the g(x) equation
g(-4)= 1-3(-4)
Use pemdas
g(-4)= 1+12
g(-4)= 13
Next you plug 13 into the f(x) equation
f(13)= 13^2 + 2
First you do 13^2=169
Add 2 and you get 171
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
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

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?
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
