Answer:

  8/9

Step-by-step explanation:

You want to know the least fraction of the distribution that lies between 61 and 79 if the mean is 70 and the standard deviation is 3.

Chebyshev's inequality tells you that at most 1/k² of the distribution will lie beyond k standard deviations from the mean.

Here, the given limits are (61 -70)/3 = -3 and (79 -70)/3 = 3 standard deviations from the mean. That is, we can use k=3 to find the maximum fraction that is beyond the interval [61, 79]. That fraction is ...

  1/k² = 1/3² = 1/9

Since this is the maximum fraction outside the given range, the minimum fraction inside the given range is ...

  1 -1/9 = 8/9

At least 8/9 of the number are between 61 and 79.

The hοle needs tο be 39 inches deeper.

A cοnversiοn factοr is a number used tο change οne set οf units tο anοther, by multiplying οr dividing. When a cοnversiοn is necessary, the apprοpriate cοnversiοn factοr tο an equal value must be used. Fοr example, tο cοnvert inches tο feet, the apprοpriate cοnversiοn value is 12 inches equals 1 fοοt.

The current depth οf the hοle is 2 feet 9 inches, which is the same as 2 + 9/12 = 2.75 feet (since there are 12 inches in 1 fοοt).

Tο find οut hοw much deeper the hοle needs tο be, we need tο subtract the current depth frοm the required depth:

6 feet - 2.75 feet = 3.25 feet

Hοwever, we are asked tο express the answer in inches, sο we need tο cοnvert the 3.25 feet tο inches using the given cοnversiοn factοr:

3.25 feet x 12 inches/1 fοοt = 39 inches

Therefοre, the hοle needs tο be 39 inches deeper.

Edit: I didn't see that there was a chart at the bottom of the pic; Desmos can still give points, but your x & y intercepts are two points, regardless

Step-by-step explanation:

Asymptote: the denominator cannot equal zero

D: x cannot equal 2

y int: set x=0 and solve

Answer:

Step-by-step explanation:

D: ( - ∞ , - 2 ) ∪ ( - 2 , ∞ )

R: ( - ∞ , 3 ) ∪ ( 3 , ∞ )

Asymptotes: x = - 2 , y = 3

x - int. ( x , 0 ) :

\(\frac{-1}{x+2}\) + 3 = 0

\(\frac{-1}{x+2}\) = - 3

x + 2 = \(\frac{1}{3}\)

x = - 1 \(\frac{2}{3}\)

( - 1 \(\frac{2}{3}\) , 0 ) are coordinates of x - intercept.

y - int. ( 0 , y ) :

- 1 ÷ ( 0 + 2 ) + 3 = 2 \(\frac{1}{2}\)

( 0 , 2 \(\frac{1}{2}\) ) are coordinates of y - intercept.

\(y = -1.25 x^{2}+ 5\)  is the needed quadratic function in standard form.

A quadratic equation is one with a single degree 2-variable and has the general form  \(a x^{2} + bx + c = 0.\)  a, b, and c is the constant value, and x consists of a variable.

The quadratic equation's x-intercepts are (-5, 0). That indicated that the quadratic equation's two elements are (x + 5) and (x -0).

f(x) = a (x + 5) (x - 0) (x - 0)

= ax+5a

f(x) = \(ax^{2} +5x\)

The quadratic equation's graph goes through (4, 0). Therefore, we must change equation 1 to read x = 4 and f(x) = 0.

0 = a × 4² + (5 × 4)

0 = a × 16 +20

a = \(\frac{-20}{16}\)

=-1.25

The quadratic equation is known to have the form ax² + bx + c = 0.

f(x) = -1.25\(x^{2}\) + 5x  

Consider y= F(x)

∴ The required quadratic equation of function in the standard form is Y = -1.25 x² + 5x.

If m = -5 or m = 3, the system of linear equations has no solution.

To determine the values of m for which the system of linear equations has no solution, we need to check the determinant of the coefficient matrix, which is:

| 3 m |

| m+2 5 |

The determinant is

=  (3 x 5) - (m x (m+2))

= 15 - m^2 - 2m

= -(m^2 + 2m - 15)

= -(m+5)(m-3)

So, for the system to have no solution, the determinant must be zero, so we have:

-(m+5)(m-3) = 0

This gives us two values of m: m = -5 and m = 3.

Thus, if m = -5 or m = 3, the system of linear equations has no solution.

Answer: y=-5x+2

Step-by-step explanation: Luckily for you, they already pretty much gave you all the information you need for this problem. Keep in mind that the standard form for linear equations is y=mx+b, where m is slope and b is figure 0, or the y-intercept. So, all you have to do is substitute the values for the given information. You know that -5 is the slope, m, and (0,2) is the y-intercept, or b (you know that this is the y-intercept because x is at zero). So, you'd be left with y=-5x+2.

To show that the angle bisector of an equilateral triangle is perpendicular to the base​, we can assume an equilateral triangle with sides ABC. Next, we can get an angle bisector in the middle represented by BD which becomes perpendicular to the base BC.  

After getting the angle bisector, we would see that the line segment BD, divides angle BAC into two equal angles, each measuring 30 degrees. Now, we can draw a perpendicular line from point D to the base BC.

We could also draw a line E, which is the perpendicular line that intersects the base BC. We want to show that BD is perpendicular to BC, which means we need to show that angle BDE is a right angle.

Since the sum of angles BDA and ADE is 90 degrees (they form a right angle), and the sum of angles BAD, ABD, and BDA is 180 degrees, it follows that angle BDE must be a right angle.

Therefore, we have shown that the angle bisector of an equilateral triangle is perpendicular to the base.

Explanation:

Segment AW bisects angle CAD.

This leads to the smaller pieces (angles CAW and DAW) to be equal to one another. Both are 20 degrees each. That totals to 20+20 = 40 degrees.

Therefore, angle CAD = 40 degrees.

The supplement of this is angle DAX

(angle CAD) + (angle DAX) = 180

angle DAX = 180 - (angle CAD)

angle DAX = 180 - 40

angle DAX = 140 degrees

About 80 necklaces have more than 28 beads. Then the correct option is C.

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The numbers of beads on 500 handcrafted bead necklaces follow a normal distribution whose mean is 24 beads and the standard deviation is 4 beads.

P(x > 28) = P(x - 24 / 4 > 28 - 24 / 4)

P(x > 28) = P(x - 24 / 4 > 1)

P(x > 28) = 1 - ∅1

P(x > 28) = 1 - 0.8413

P(x > 28) = 0.1587

Multiply both sides by 500, then we have

500 P(x > 28) = 0.1587 × 500

500 P(x > 28) = 79.35

500 P(x > 28) ≈ 80

Answer:

Step-by-step explanation:

real number can be irrational or integer.

otherwise there is no number which can be irrational,integer and real (all together)

Answer: The answer is B) there is no such number.

Step-by-step explanation:

So we have to find which number is irrational, and integer, and a real number. Let's examine the problem closely:

- irrational means not rational and cannot be represented by a simple fraction (like pi )

- an integer means a number that can be written without a fractional component ( -1, 2, 0, -10000 )

- and a real number means that it is not imaginary ( like 2i, \(\sqrt{-1}\) )

And our choices here are:

-  -4/2

-  there is no such number

Let's take a look at -4/2. This number is a fraction, but it can be simplified down to -2/1, which is an integer. -2 is a real number, not an imaginary number. But, -2 is not irrational, because as it just was shown here, it CAN be represented by a fraction. So, since only two out of the three criteria are true, then we have to consider choice B.
