Find z:

Answer:

x=10

y = 21°

z=8°

Step-by-step explanation:

we have

AB = AD, CB = CD,

AC perpendicular to DB, AC is angle bisector of DAB and DCB

Perimeter = 140

2(2x + 7 + 4x +3) = 140

6x + 10 = 70

6x = 60

x = 60/6=10

x=10

again

3y - 1 +28° =90

3y - 1 = 90° - 28°

3y - 1 = 62°

3y = 63°

y = 21°

again

4z+58°=90

4z = 90° - 58

4z = 32°

z=32/4

z=8°

The probability that Dave will select a gray T-shirt is 13 / 25.

The odds in favor of picking a gray T-shirt is 13 : 25

Probability is used to calculate the odds that are in favor or against a random event happening. The odds in favor or against a random event happening has a probability value that lies between 0 and 1. The higher the odds that are in favor of the event happening, the closer the probability value would be to 1.

The probability that Dave will select a gray T-shirt = number of gray T-shirts / total number of T-shirts

13 / 25

Ratio is used to compare two or more numbers together.

The odds in favor of picking a gray T-shirt = number of gray T-shirt : total number of T-shirts = 13 : 25

Step-by-step explanation:

A. The functions are given as follows:

B. The company from which the family should rent the truck is: Company Y.

There are two costs in the problem, given as follows:

The fixed costs for Company X are given as follows:

The variable cost is of 0.59 per mile, hence the function, considering a trip of m miles, is given as follows:

X(m) = 59.90 + 150 + 36 + 0.59m.

X(m) = 245.9 + 0.59m.

The fixed costs for Company Y are given as follows:

The variable cost is of 0.79 per mile, hence the function, considering a trip of m miles, is given as follows:

Y(m) = 39.90 + 52 + 0.79m

Y(m) = 91.9 + 0.79m.

The trip is of 750 miles, hence the costs are given as follows:

Due to the lower cost, Company Y should be chosen.

Option 2 is the correct graph for the function f(x) = \(4[(1/2)^{x}]\) .

Given ,

f(x) = \(4[(1/2)^{x}]\)

Mathematically the graph will of exponential in nature.

So,

Let us assume few values to understand the nature of graph.

Firstly,

Let x= 1

f(x) = \(4[(1/2)^{1}]\)

f(x) = 2

Let x = 2

f(x) = \(4[(1/2)^{2}]\)

The volume of cylinder is denoted as πr²h

The density of a cylinder is determined by its volume, which indicates how much material it can hold or how much can be submerged inside it. The volume of a cylinder can be calculated using the formula r2h, where r denotes the radius of the circular base and h denotes the height of the cylinder. Any substance that can be evenly put into the cylinder, including liquid, may be used as the material. Shape volumes can be seen here.

This article contains a basic explanation of cylinder volume as well as examples with solutions for your convenience. The study of shapes and their characteristics is a key component of geometry in mathematics. Any three-dimensional shape must have both volume and surface area.

Hence, the volume of cylinder is denoted as πr²h

The x-axis of this graph is D) Individuals' life spans as a percentage of the maximum life span for the species.

In mathematics, "graph" can refer to (at least) two different things. The word "graph" in elementary mathematics refers to a plot or a function graph.

A graph is, in the language of mathematicians, a set of points and the connections between some subset of those points (which may be empty).

Making a diagram that shows the link between two or more objects is known as developing a graph. Create a graph by placing a series of bars on graph paper.

Depending on age, survival curves display the likelihood of survival in a population. The y-axis represents the number of survivors (on a log scale), while the x-axis represents time (indicating relative age). The graph's x-axis (horizontal line) should contain the independent variable, and the y-axis should contain the dependent variable. At the origin, where the coordinates are, the x and y axes intersect.

Answer:

y=(x-2)^2-81

Step-by-step explanation:

The smallest value (minimum) among the following (3.11, 0.956, 36, 4.21, or 10.1) is 0.956.

The smallest value refers to the minimum value among the data set values.

The opposite of the smallest value is the maximum value or the largest value.

In these values, 3.11, 0.956, 36, 4.21, or 10.1, 0.956 is obviously the smallest because it is less than 1, whereas other values are more than 1 and it represents a proper fraction, unlike the other improper fractional values.

Thus, we can conclude that 0.956 is a fractional value depicted as a decimal, unlike other values that combine whole numbers with some fractions.

Which of the following is the smallest value, 3.11, 0.956, 36, 4.21, or 10.1

Step-by-step explanation:

Since DE is a midsegment, it divides the side AB into two congruent segments. Therefore, we can conclude that angle ADE is congruent to angle BDE. Using this fact and the given angle measures, we can set up an equation and solve for x:

ADE = BDE (since DE is a midsegment)

3x + 7 = 5x - 2 (substitute the given angle measures)

7 = 2x - 2 (subtract 3x from both sides)

9 = 2x (add 2 to both sides)

x = 4.5

Therefore, the solution is x = 4.5.

Answer:

The nth term is Tn = 2[T(n- 1) -2]

The next term is 356

Step-by-step explanation:

Given

Terms: 15,26,48,92,180

Solving (a) : The recursive n term

We have:

T1 = 15

T2 = 26 = 13 * 2 = (15 - 2) * 2

T3 = 48 = 24 * 2 = (26 - 2) * 2

T4 = 92 = 46 * 2 = (48 - 2) * 2

T5 = 180 = 90 * 2 = (92 - 2) * 2

So, the nth term can be represented as:

Tn = [T(n-1) - 2] * 2

Tn = 2[T(n-1) - 2]

The next term is the 6th term.

So, substitute 6 for n in the above formula.

T6 = 2 * [T(6 - 1) - 2]

T6 = 2 * [T5 - 2]

Substitute 180 for T5

T6 = 2 * (180 - 2)

T6 = 2 * 178

T6 = 356

The graph of the equation y=2x+1 shows a straight line, or it is a linear equation. When the value of x rises, eventually the value of y rises by twice the rise in x plus one. With a ruler and the specified amount as the starting point, draw a vertical line. From the line across to the -axis, create a horizontal line using a ruler. Look at the value on the -axis.

There are three fundamental ways to graph linear functions. The initial method involves charting points and then tracing a line through them. The second is by using the slope and y-intercept. The identity function f(x)=x is transformed as the third method.

20 pages of Daniel's book had pictures.

If 1/12 of the pages in Daniel's book had pictures, we can calculate the number of pages with pictures by multiplying the total number of pages in the book by 1/12:

240 pages x (1/12) = 20 pages

To find the number of pages with pictures in the entire book, we need to determine how many groups of 12 pages there are in the book and then multiply that number by the number of pages with pictures in each group (which is one page). We can do this by multiplying the total number of pages in the book (240) by the fraction 1/12, which gives us 20 pages with pictures in the book.

P(A∪B)=4/5, P(C)=2/5,  \(P(AUB^c)=\frac{3}{5}\), n(BUC)=4.

The given information is: U = {E1, E2, E3, E4, E5}, A = {E1, E2} B = {E3, E4} C = {E2, E3, E5}

Total number of outcomes = 5

From the given information, we get

n(U)=5,n(a)=2,n(B)=3, n(C)=3

The formula for probability:

Probability=number of favorable/number of total outcomes.

(a) To Find P(A), P(B), and P(C):

\(P(A)=\frac{n(A)}{n(U)} \\\\P(B)=\frac{n(B)}{n(U)} \\\\P(C)=\frac{n(C)}{n(U)}\)

(b) To Find P(A U B):

Now We should find P(AUB) if A and B are mutually exclusive.

P(A∩B)=0

P(A∪B)=P(A)+P(B)-P(A∩B).

P(A∪B)=P(A)+P(B).

P(A∪B)=2/5+2/5

P(AUB)=4/5

c)

\(A^c=U-A=[E1, E2, E3, E4, E5]- [E1, E2]=E_3,E_4,E_5\)

Number of elements in \(A^c\)=3.

\(n(A^c)=3\)

\(P(A^c)=\frac{n(A^c)}{n(u)} =\frac{3}{5}\\\\ C^c=U-C=[E1, E2, E3, E4, E5]-[{E2, E3, E5}]=E_1,E_4\)

Number of elements in \(C^c\)= 2

\(n(C^c)=2\\\\P(c^c)=2/5\)
