Answer:

1.78

Step-by-step explanation:

To solve for x  we need to cross multiply it

We have = sign in between the fractions so we cross multiply it

9*x = 2* 8

9x = 16

Now we divide by 9 on both sides

so x= 1.7777777778

When we round to two decimal places then

x= 1.78

What is 5/15 written as a decimal???

Answers

the first when you do is divide 15 by 5 and you get 3 so. 0.333333 number 2 is 0.26666 the 3rd is 1 divided by 5 equals 0.2
Hello!

There are a couple ways we can use to convert a fraction to a decimal, but let's stick with the easiest one.

To convert a fraction to a decimal, simply divide the numerator (top part of the fraction) by the denominator (bottom part).

The first fraction is 5/15. Its numerator is 5, and its denominator is 15. Divide the top by the bottom.

5 ÷ 15 = 0.3333333333

Because this decimal keeps repeating, it is called a "repeating fraction."

We don't want to write all those 3's over and over again, so to indicate that it is a repeating decimal, simply put a bar above the 3.

Convert the other two fractions using the same method:

4 ÷ 15 = 0.266666667

Remember to put a bar above the repeating number.

3 ÷ 15 = 0.2

Since this decimal does not repeat, it is called a "terminating decimal". You do not have to put a bar above the 2.

Don't forget this method!

In a homicide case 33 different witnesses picked the same man from a line up. the line up contained 5 men. if the identifications were made by random​ guesses, find the probability that all 33 witnesses would pick the same person. round to seven decimal places.

Answers

the correct question in the attached figure

we know that

the probability
that a witness picks a particular person by chance-----> P=1/5

the probability
that all 7 witnesses would pick the same person-----> P=1/5^7=0.0000128

the answer is the option B 0.0000128

There are a variety of problems in which the number of witnesses change, for example
....find the probability that all 9 witnesses would pick the same person

in this case, the probability would be-------> P=1/5^9=0.000000512

Final answer:

The probability that Nancy is a robber given Bob's identification is around 33.2%, considering Bob's accuracy and the base rate of robbers in the population.

Explanation:

Probability Calculation:

To find the probability that Nancy is a robber given Bob's identification, we use Bayes' Theorem. Given that Bob is 99% accurate in identifying suspects, the calculation reveals that the probability that Nancy is a robber is around 33.2%.

Base Rate Fallacy: It is crucial to consider the base rate of robbers in the population to avoid common statistical errors in interpreting the probability of an event.

How can Brady use fraction strips to show that 3 4 and 7 8 are NOT equivalent?

Answers

Brady needs three strips that each represent one fourth (1/4). He needs to line them up end to end. The new long strip he has created represents 3/4.

Next Brady needs seven strips that each represent one eighth (1/8). He needs to line them up end to end. The new long strip he has created represents 7/8.

If the two long strips he created were equal then 3/4 would equal 7/8 but as they are not equal this is not the case. Since the strip for 7/8 is longer, the fraction 7/8 is greater than 3/4.
Final answer:

To demonstrate that 3/4 and 7/8 are not equivalent, Brady can use fraction strips to visually compare the colored portions of the strips, which will clearly show that 7/8 is greater than 3/4 as it has more colored sections.

Explanation:

To show that 3/4 and 7/8 are not equivalent using fraction strips, Brady can follow these steps:

Take one strip and divide it into four equal parts to represent the fraction 3/4. Color three of these parts.Take another strip, divide it into eight equal parts to represent the fraction 7/8, and color seven of these parts.Compare the two colored strips side by side.

Brady will observe that the strip representing 7/8 has more colored sections than the strip representing 3/4, even though the strips are the same length. This visual comparison confirms that 3/4 is less than 7/8, thus they are not equivalent fractions. The fraction 7/8 is only one-eighth away from being a whole, whereas 3/4 is one-fourth away.

B. $39,600.00
C. $88,712.07
D. $93,429.71

Answers

if im not wrong then i sure its C

Answer:

After 35 years balance in the account  = $93429.71

Explanation:

We will applying the compound interest formula.

A = [tex] P(1 +\frac{r}{n})^{nt}  [/tex]

Where,

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per year

t = the number of years

Given that,

P = $6000

r = 8% = [tex] \frac{8}{100}  [/tex] = 0.08

n = 2 (because of twice in a year)

t = 35 years

[tex] A= 6000(1 + \frac{0.08}{2}) ^{2*35}  [/tex]

A = 6000[tex] (1.04)^{70}  [/tex]

A= $93429.71    (Option D)

Why is it most logical to let x represent Dianna’s current age?

Answers

let's say Diana is "x" years old today.

in 3 years, she's going to be " x + 3 " years old.

33 years ago, she was " x - 33 " old.

how much is 4 times that anyway?  well 4(x-33), that's 4 times as 33 years ago her age.

now, we know in 3 years, x+3, she'll be "4 times as old as she was 33 years ago", 4(x-33), therefore, those amounts are equal then,

[tex]\bf \stackrel{\textit{3 years from now}}{x+3}~~=~~\stackrel{\textit{4 times as old as she was 33 years ago}}{4(x-33)} \\\\\\ x+3=4x-132\implies 135=3x\implies \cfrac{135}{3}=x\implies 45=x[/tex]

why is it most logical to use "x" for her age today?

well, because 3 years from now is just x + 3
and
33 years ago is x - 33, 4 times that is 4( x - 33 ).

works very well as a point of reference.

Answers

1. Rewrite the system:

 x+12y=68  (i)
 x=8y-12   (ii)

 2. Let's substitute the equation (ii) into the equation (i):

 x+12y=68
 (8y-12)+12y=68

 3. Then, you have:

 8y-12+12y=68

 4. When you clear "y", you have:

 20y-12=68
 20y=68+12
 20y=80
 y=80/20
 y=4

 5. You already have the value of "y". Now, you must substitute this value into the equation (ii):

 x=8y-12
 x=8(4)-12
 x=32-12
 x=20

 6. Therefore, the result is:

 x=20
 y=4

Roderick wants to draw a circle for which the numerical value of the circumference is greater than the value of the area. Which lengths could he use for the radius? Check all that apply.

Answers

Answer:

The length of the radius must be less than [tex]2[/tex]

[tex]\frac{1}{2},1,1.5[/tex]

Step-by-step explanation:

we know that

The circumference of a circle is equal to

[tex]C=2\pi r[/tex]

The area of a circle is equal to

[tex]A=\pi r^{2}[/tex]

where r is the radius of the circle

In this problem we have that

[tex]C > A[/tex]

Substitute

[tex]2\pi r > \pi r^{2}[/tex]

Simplify

[tex]2r > r^{2}[/tex]

[tex]2> r[/tex] ------> rewrite

[tex] r< 2\ units [/tex]

The length of the radius must be less than [tex]2[/tex]

the answer is

[tex]\frac{1}{2},1,1.5[/tex]

Roderick select the length of radius, for keeping the value of circumference of the circle greater than the value of its area, should be 1/2,1 and 1.5. Thus the option A, B and C is the correct option.

What is circumference and area of the circle?

Circumference of the circle is the length of its boundary. It can given as,

[tex]P=2\pi r[/tex]

The area of the circle is the space occupied by it. It can be given as,

[tex]A=\pi r^2[/tex]

Given information-

Roderick wants to draw a circle.

The circumference of the circle must be greater than the area of the circle.

The circumference of the circle having radius equal to [tex]r[/tex] units can be given as,

[tex]P=2\pi r[/tex]

The area of the circle having radius equal to [tex]r[/tex] units can be given as,

[tex]A=\pi r^2[/tex]

Now as Roderick wants to draw a circle in which, the circumference of the circle must be greater than the area of the circle. Thus,

[tex]P>A[/tex]

Put the values as,

[tex]2\pi r>\pi r^2\\2r>r^2\\2>r[/tex]

Thus the value of the  radius of Roderick circle must be less than the number 2.

Number 1/2 , 1, and 1.5 is less than the number two.

Thus, Roderick select the length of radius, for keeping the value of circumference of the circle greater than the value of its area, should be 1/2,1 and 1.5. Thus the option A, B and C is the correct option.

Do 1.5 cm, 3 cm, 1.5 cm make a triangle and what kind

Answers

Don't really know how to explain making one but the triangle will be a isosceles for sure. 

The lengths 1.5 cm, 3 cm, and 1.5 cm cannot form a triangle because the sum of the lengths of the two shorter sides is equal to the length of the longest side, which does not satisfy the Triangle Inequality Theorem.

The question asks if lengths 1.5 cm, 3 cm, and 1.5 cm can form a triangle, and if so, what kind of triangle it would be. To determine whether these lengths can form a triangle, we use the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

For these lengths:

1.5 cm + 1.5 cm = 3 cm1.5 cm + 3 cm > 1.5 cm1.5 cm + 3 cm > 1.5 cm

We see that when we add the lengths of the two shorter sides (1.5 cm + 1.5 cm), it equals the length of the longest side (3 cm). According to the Triangle Inequality Theorem, the lengths do not meet the condition for forming a triangle because the sum must be greater than, not equal to, the length of the third side. Therefore, these lengths cannot form a triangle.

 4x+1 = 25

      x = 6

Answer:

[tex]x=6[/tex]

Step-by-step explanation:

We have been given a triangle and we are asked to solve for x using angle bisector theorem.

Angle bisector theorem states that if a ray bisects an angle of a triangle, then it divides the opposite side of triangle into segments that are proportional to the other two sides.

Using angle bisector theorem we can set an equation as:

[tex]\frac{4x+1}{5}=\frac{15}{3}[/tex]

Let us solve for x by multiplying both sides of our equation by 5.

[tex]\frac{4x+1}{5}*5=\frac{15}{3}*5[/tex]

[tex]4x+1=5*5[/tex]

[tex]4x+1=25[/tex]

Let us subtract 1 form both sides of our equation.

[tex]4x+1-1=25-1[/tex]

[tex]4x=24[/tex]

Upon dividing both sides of our equation by 4 we will get,

[tex]\frac{4x}{4}=\frac{24}{4}[/tex]

[tex]x=6[/tex]

Therefore, the value of x is 6 units.
