write the ratio as fraction in simplest form with whole numbers in the numerator and denominator. 12m : 32m (PICTURE)​

Answer:

0.48

0.52

No

Yes

Step-by-step explanation:

Result of experiment :

Point up = 48

Point down = 52

Total number of trials = 100

Recall :

Experimental probability = number of outcomes / number of trials

1.)

P(Landing point up) = 48 / 100 = 0.48

2.)

P(Landing point down) = 52 / 100 = 0.52

3.)

The same result will not occur has the outcomes of trials aren't fixed.

4.) Yes, nearly the same result could occur on the second trial, as the number of possible outcubes are just 2 and the number if trials is high.

Answer:

There's is a 25% chance on having all 6 births be girls. There is a 50-50 chance of a boy nor a girl. However, it is possible.

The probability of having 6 ​girls will be 1/64.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

In a family with 6 ​children, excluding multiple​ births.

Then the probability of having 6 ​girls will be

Leaving out the third gender, let's suppose that there is an equal chance of having a girl or a boy.

Any child can be either a boy or a girl, with each having equal probability of = 1/2

Each of these blank spaces can be filled in 2 ways : B and G (denoting 'B' and 'G' respectively)

Probability of first blank being a ''G' is = 1/2

and second blanks too being a “G” is = 1/2

Thus, probability of each blank individually being a “G” = 1/2

Thus, probability of all being a “G” = (1/2) (1/2)  (1/2) (1/2) (1/2)* (1/2) = (1/2)6 = 1/64

Thus, probability of 6 children being all 6 girls = 1/64

Step-by-step explanation:

remember that

[tex] \displaystyle a \rm cis( \theta) \times b cis( \theta _{2}) = ab \cdot cis( \theta + \theta _{2})[/tex]

so we acquire:

[tex] \displaystyle \frac{ \sqrt{2} }{6} \rm cis \left( \frac{3\pi}{5} \right) \times \frac{ \sqrt{6} }{4} cis \left( \frac{2\pi}{3} \right) = \frac{ \sqrt{2} }{6} \times \frac{ \sqrt{6} }{4} \cdot cis \left( \frac{3\pi}{5} + \frac{2\pi}{3} \right)[/tex]

Answer:

  -9

Step-by-step explanation:

You are given a point and a slope, so you can write the equation of the line in point-slope form:

  y -k = m(x -h) . . . . . line of slope m through point (h, k)

  y -7 = 4(x +5) . . . . using the given point

Putting in the x- and y-values of the other point, we have ...

  -9 -7 = 4(w +5)

  -4 = w +5 . . . . . . . . . divide by 4

  -9 = w . . . . . . . . . . subtract 5

The value of w is -9.

Answer:

The minimum sample size needed is [tex]n = (\frac{1.96\sqrt{\sigma}}{4})^2[/tex]. If n is a decimal number, it is rounded up to the next integer. [tex]\sigma[/tex] is the standard deviation of the population.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.9}{2} = 0.05[/tex]

Now, we have to find z in the Z-table as such z has a p-value of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.05 = 0.95[/tex], so Z = 1.645.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

How large a sample must she select if she desires to be 90% confident that her estimate is within 4 ounces of the true mean?

A sample of n is needed, and n is found when M = 4. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]4 = 1.96\frac{\sigma}{\sqrt{n}}[/tex]

[tex]4\sqrt{n} = 1.96\sqrt{\sigma}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{\sigma}}{4}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{\sigma}}{4})^2[/tex]

[tex]n = (\frac{1.96\sqrt{\sigma}}{4})^2[/tex]

The minimum sample size needed is [tex]n = (\frac{1.96\sqrt{\sigma}}{4})^2[/tex]. If n is a decimal number, it is rounded up to the next integer. [tex]\sigma[/tex] is the standard deviation of the population.

Answer:

x= 2, y= 8

Step-by-step explanation:

y= 3x +2 -----(1)

y= -2x +12 -----(2)

Substitute (1) into (2):

3x +2= -2x +12

Move x terms to 1 side, constant to the other:

3x +2x= 12 -2

Simplify:

5x= 10

Divide both sides by 5:

x= 10 ÷5

x= 2

Substitute x=2 into (1):

y= 3(2) +2

y= 6 +2

y= 8

The radius of the sphere is approximately 4.2 feet.

To find the volume of a specific sphere, we need to know its radius. Once we have the radius, we can plug it into the formula and calculate the volume.

The formula for the volume of a sphere is:

V = (4/3) x π x r^3

where V is the volume of the sphere, r is its radius, and π is a mathematical constant approximately equal to 3.14.

We are given the volume of the sphere, so we can plug it into the formula and solve for the radius:

384 = (4/3)  x π  x r^3

Dividing both sides by (4/3) x π, we get:

r³ = 384 / ((4/3) x π)

r³ = 72.825

Taking the cube root of both sides, we get:

r ≈ 4.243

The radius of the sphere is approximately 4.2 feet.

$38,025.04

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 8.4/100

r = 0.084 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 1,200.00(1 + 0.084/2)(2)(42)

A = 1,200.00(1 + 0.042)(84)

A = $38,025.04

Answer:

You multiply the probabilities together.  The probability of rolling an odd number is 1/2 (because half of the numbers on a number cube are odd).  The probability of rolling a number greater than 1 is 5/6 because 5 of the 6 numbers are greater than 1.  Then multiply those two fractions together to get your answer.

B) 6x + 16 = 82

Note: I just kept my wrong approach.

Step-by-step explanation:

Let first define an odd integer.

Considering [tex]x\in\mathbb{Z}: 2k+1[/tex], [tex]x[/tex] is an odd integer.

Now, three consecutive odd integers are [tex]a_1 = 2k+1[/tex] , [tex]a_2 = 2k+3[/tex] and [tex]a_3 = 2k+5[/tex]

The sum of the​ first, two times the second and three times the third can be written as

[tex]a_1 + 2a_2 + 3a_3 = 2k+1 + 2(2k+3)+3(2k+5)[/tex]

Expanding and simplifying

[tex]2k+1 + 2(2k+3)+3(2k+5) = 2k+1 +4k+6+6k+15 = 12k+22[/tex]

This is what I have done initially, but considering [tex]x[/tex] to be an odd integer, three consecutive integers can be written as

[tex]x, x+2, x+4[/tex] such that [tex]x\in\mathbb{Z}: 2k+1[/tex]

Therefore,

[tex]x+2(x+2)+3(x+4)=82 \implies x+2x+4+3x+12 = 82 \implies 6x+16 = 82[/tex]

and [tex]6x+16 = 82 \implies 6x = 66 \implies x = 11[/tex]

The three consecutive odd integers such that the sum of the​ first, two times the second and three times the third is 82 are [tex]11, 13, 15[/tex]

Answer:

y= -1/3(x) + 8

Step-by-step explanation:

slope of the 1st line = 3

slope of the line perpendicular to the first is its opposite reciprocal, so

slope of the 2nd line = -1/3

now we have a point and the slope of the perpendicular line, so we use the point slope formula to get:

y-7=-1/3(x-3)

y= -1/3(x) + 1 + 7

y= -1/3(x) + 8

Answer:

X = -6 - 3y

Y = -1

Step-by-step explanation: Solve for X first using basic algebra. Plug in X vaalue to original equation and solve. -6 - 3y + 3y = -6. Solve by adding 6 to both sides of the equation and dividing -3y by 3y.
