May I Get Help, I Know I Have To Multiply The Possibilities, But I Keep Getting Stuck

Answers

Answer 1

First we obtain each probability

The land has no oil

is a 45% chance that the land has oli , then the chance that the land has not oil is 55%

55% can be represented like 0.55

then the probability to the land has no oil is 0.55

The test shows that there is no oil

Kit claims to have an 80% of idicating oil, then the percent that there is no oil is 20%

20% can be represented like 0.2

the tne probability to shows that theere is no oil is 0.2

Finally

Multiply the probabilities to find the probability that say the land has no oil and the test shows that there is no oil

[tex]0.55\times0.2=0.11[/tex]

then irhg toption is B

B. Are the graphs of y = a|x| and y = |ax| the same when a is negative? Why?

Answers

The absolute value gives always a positive number.

If a is negative, then a|x| is negative and |ax| is positive.

Therefore, the graph of y=a|x| won't be the same as the graph of y=|ax|.

Another way to see it, is by using the property:

[tex]\mleft|ax\mright|=\mleft|a\mright|\cdot\mleft|x\mright|[/tex]

Since a is negative, then |a| = -a. So, |ax| = -a|x|, which is clearly different from a|x|.

Leeds Company produced the following number of maps during the first five weeks of last year. Prepare a bar graph. Week Maps 1 800 2 600 3 400 4 700 5 300

Answers

The bar graph is attached below.

The heights of the rectangular bars in a bar graph, which displays complete data, are proportionate to the values they indicate. The graph's bars can be displayed either vertically or horizontally. Bar graphs, commonly referred to as bar charts, are a visual depiction of groups of data. It is one method of processing data. A bar graph is a great tool for representing data that are unrelated to one another and do not need to be displayed in any particular sequence. The bars provide a visual representation for comparing amounts in several categories. The x and y axes, commonly known as the horizontal and vertical axes, the title, labels, and a bar graph are all included.

Hence we frame the desired bar graph.

consider the following linear equation 5x-5y=15 determine the slope and Y-intercept (entered as an ordered x and y pair) of the equation

Answers

The first step to solve this problem is to rewrite the equation in slope intercept form, to do it, solve the given equation for y:

[tex]\begin{gathered} 5x-5y=15 \\ -5y=-5x+15 \\ y=x-3 \end{gathered}[/tex]

According to this, the slope of the line is 1.

The y intercept is (0,-3).

The line graphed should look like this:

Complete the equation of the line through (-7,-3) and (-2,4)

Answers

If one line passes through the points (x₁, y₁) and (x₂, y), the slope of the line can be calculated using the formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}...(1)[/tex]

Additionally, the equation can be expressed in point-slope form as:

[tex]y-y_2=m(x-x_2)...(2)[/tex]

From the problem, we identify:

[tex]\begin{gathered} (x_1,y_1)=(-7,-3) \\ \\ (x_2,y_2)=(-2,4) \end{gathered}[/tex]

Then, we calculate the slope of the line using (1):

[tex]m=\frac{4-(-3)}{-2-(-7)}=\frac{4+3}{-2+7}=\frac{7}{5}[/tex]

Finally, we find the equation of the line using (2):

[tex]\therefore y-4=\frac{7}{5}(x+2)[/tex]

what is the measure in radians of central angle 0 in the circle below

Answers

For this exercise you need to use the following formula:

[tex]\theta=\frac{S}{r}[/tex]

Where θ is the Central angle in radians, "S" is the arc length and "r" is the radius of the circle.

In this case, you can identify that:

[tex]\begin{gathered} S=8\pi cm \\ r=8\operatorname{cm} \end{gathered}[/tex]

Knowing these values, you can substitute them into the formula and then evaluate, in order to find the measure of the Central angle in radians. This is:

[tex]\begin{gathered} \theta=\frac{8\pi cm}{8\operatorname{cm}} \\ \\ \theta\approx\pi radians \end{gathered}[/tex]

In one us city the taxi cost is 2$ plus .50c per mile . If you are traveling from the airport there is an additional charge of 3.50$ for tolls how far can i travel for 33$

Answers

Let the number of miles I can travel for $33 be x;

The total cost of taxi ride from the airport is;

Flat fee + Tolls fee + Charge/Mile = Total cost

Flat fee = $2.00

Toll fee = $3.50

Charge per mile = 0.50x

Total cost = $33.00

Thus, we have;

[tex]\begin{gathered} 2.00+3.50+0.50x=33.00 \\ 0.50x=33.00-5.50 \\ 0.50x=27.50 \\ x=\frac{27.50}{0.50} \\ x=55 \end{gathered}[/tex]

Chips (x) Chips (y) 200 100 160 140 120 180 80 220 Hint: use your calculator (STAT: Edit)

Answers

step 1

Find the slope m

we need two points

so

(200,100) and (80,220)

m=(220-100)/(80-200)

m=120/-20

m=-6

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=-6

(x1,y1)=(200,100)

substitute

y-100=-6(x-200)

Convert to slope intercept form

y-100=-6x+1200

y=-6x+1300

step 3

Find the equation in standard form

Ax+By=C

where

A is a positive integer

B and C are integers

so

y=-6x+1300

The formula, = / + , converts temperatures between Celsius and Fahrenheit degrees. What is the temperature in degrees Celsius that is equivalent to 14 degrees FahrenheitA) -10B) -9 C) -8D) -7

Answers

Hello there. To answer this question, we need to plug in the value given by the question and solve for C, the temperature in Celsius.

We want to find the equivalent temperature in Celsius to 14 degrees Fahrenheit.

Knowing that F = 9/5C + 32, making F = 14 lead us to:

14 = 9/5C + 32

Subtract 32 on both sides of the equation

9/5C = -18

Multiply both sides of the equation by a factor of 5/9, in order to get:

C = 5/9 (-18) = -10.

This is the equivalent temperature we were looking for.

In the diagram below of rhombus ABCD,angle C is 100,what is angle DBC

Answers

Okay, here we have this:

Considering the provided information, that in a rhombus opposite angles are equal, and that the sum of the angles of a triangle is 360 °, we obtain:

360°=100°+100°+4(m∠DBC)

Now, let's clear "m∠DBC":

360°=200°+4(m∠DBC)

4(m∠DBC)=360°-200°

4(m∠DBC)=160°

m∠DBC=160°/4

m∠DBC=40°

Finally we obtain that the correct answer is the option A.

The first three terms of an arithmetic sequence are as follows.3, -1, -5

Answers

We will take a look at how we go about with arithmatic progressions.

Arithmmetic sequences are caetgorized by the following two parameters:

[tex]\begin{gathered} a\text{ = First term} \\ d\text{ = common difference} \end{gathered}[/tex]

Where,

[tex]\begin{gathered} \text{The value of the first term is called ( a )} \\ \text{The common difference between each and every successive value in a sequence is called ( d )} \end{gathered}[/tex]

We are given the following arithmetic sequence:

[tex]3\text{ , -1 , -5 , }\ldots[/tex]

Now we will try to determine the values of the two parameters ( a and d ) from the given sequence as follows:

[tex]\begin{gathered} a\text{ = 3 }(\text{ first term value )} \\ d\text{ = (-1 ) - ( 3 ) = (-5 ) - ( -1 ) = -4 ( common difference )} \end{gathered}[/tex]

Now to determine the value of any term number ( n ) in an arithmetic sequence we use the following formula:

[tex]a_n\text{ = a + ( n - 1 )}\cdot d[/tex]

Where,

[tex]n\text{ is the term number}[/tex]

So if we plug in the values of arithmetic sequence parameters into the general equation above we get:

[tex]\textcolor{#FF7968}{a_n}\text{\textcolor{#FF7968}{ = 3 + ( n - 1 ) }}\textcolor{#FF7968}{\cdot}\text{\textcolor{#FF7968}{ ( -4 )}}[/tex]

Now we are to determine the values of term numbers ( n = 4 ) and ( n = 5 ). We will evaluate the ( an ) for each term number as follows:

[tex]\begin{gathered} \text{\textcolor{#FF7968}{For n = 4}} \\ a_4\text{ = 3 + ( 4 - 1 )}\cdot(-4\text{ )} \\ a_4\text{ = 3 - 12} \\ \textcolor{#FF7968}{a_4}\text{\textcolor{#FF7968}{ = -9}} \\ \\ \text{\textcolor{#FF7968}{For n = 5}} \\ a_5\text{ = 3 + ( 5 - 1 )}\cdot(-4\text{ )} \\ a_5\text{ = 3 - 1}6 \\ \textcolor{#FF7968}{a_5}\text{\textcolor{#FF7968}{ = -}}\textcolor{#FF7968}{13} \end{gathered}[/tex]

Hence, the next two consecutive numbers in the arithmetic sequence would be:

[tex]3\text{ , -1 , -5 ,}\text{\textcolor{#FF7968}{ -9}}\text{ , }\text{\textcolor{#FF7968}{-13}}[/tex]
