If you flip a coin 92 times, what is the best prediction possible for the number of times it will land on tails?

Answers

Answer 1

Answer:

Hence, the probability of a head on Flip 1 and a head on Flip 2 is the product of P(H) and P(H), which is 1/2 x 1/2 = 1/4. The same calculation applies to the probability of a head on Flip 1 and a tail on Flip 2. Each is 1/2 x 1/2 = 1/4.

Step-by-step explanation:

Answer 2

Answer:

1/4 of 92 = 23 Hope this helps

Find all constants a such that the vectors (a, 4) and (2, 5) are parallel.

Answers

Answer:

[tex]\displaystyle a = \frac{8}{5}[/tex].

Step-by-step explanation:

Two vectors [tex](x_1,\, y_1)[/tex] and [tex](x_2,\, y_2)[/tex] are parallel to one another if and only if the ratio between their corresponding components are equal:

[tex]\displaystyle \frac{x_1}{x_2} = \frac{y_1}{y_2}[/tex].

Equivalently:

[tex]\displaystyle \frac{x_1}{y_1} = \frac{x_2}{y_2}[/tex].

For the two vectors in this equation to be parallel to one another:

[tex]\displaystyle \frac{a}{4} = \frac{2}{5}[/tex].

Solve for [tex]a[/tex]:

[tex]\displaystyle a = \frac{8}{5}[/tex].

[tex]\displaystyle \frac{8}{5}[/tex] would be the only valid value of [tex]a[/tex]; no other value would satisfy the [tex]\displaystyle \frac{x_1}{y_1} = \frac{x_2}{y_2}[/tex] equation.

Answers

Answer:

8 peanut cookies

Step-by-step explanation:

4 x 12  = 48

48 x  1/3 = 2/3 left             (16 chocolate chip)

48-16= 2/3 = 32 left          

32 x 3/4 = 24                     (24 gingersnaps)

32-24 = 8                          ( 8 peanut cookies)

Which of the following polynomials is guaranteed by the Intermediate Value Theorem to have a zero on the interval [−4,−1]?

Answers

Answer:

3

Step-by-step explanation:

because 4-1=3

The polynomials are not given, but we can answer in a general way.

Basically, what you need to test is:

Sign[p(-4)] ≠ Sign[p(-1)]

But let's see why.

The intermediate value theorem says that, if for two values a and b such that:

a < b

If we have a given continuous function such that:

f(a) < 0 and f(b) > 0.

or

f(a) > 0 and f(b) < 0

Then there exists a value c

a < c < b

Such that:

f(c) = 0

So to find the correct polynomial, you just need to evaluate it in both extremes of the interval and you should see that the sign changes.

This means that if p(x) is the polynomial, then you should have:

Sign[p(-4)] ≠ Sign[p(-1)]

This will imply, by the intermediate value theorem, that the polynomial is equal to zero for some given value on the given interval.

  CB +BD +CD = 360°

  CD = 360° -140° -140° = 80°

The measure of inscribed angle B is half the measure of the arc it subtends:

The altitude of a triangle is 5 less than its base. The area of the triangle is 42 square inches. Find its base and altitude.​

Answers

9514 1404 393

Answer:

  base: 12 in

  altitude: 7 in

Step-by-step explanation:

The formula for the area of a triangle is ...

  A = 1/2bh

Filling in the given information, we have ...

  42 = 1/2(b)(b -5)

  b^2 -5b -84 = 0 . . . . multiply by 2, put in standard form

  (b -12)(b +7) = 0 . . . . factor

The only positive solution is b = 12

The base is 12 inches; the altitude is 7 inches.

The mass of Sand that Carla needs to purchase for the sand tank is gotten to be; 25811 g

What is the mass required?

Formula for density is;

Density = mass/volume

From the box we are given, it's volume is;

Volume = 30 * 30 * 76

Volume = 68400 cm³

Now, from conversion;

1 cm³ = 1g. Thus;

68400 cm³ = 68400 g

Volume = Mass/density

Volume = 68400/2.65

Volume = 25811 g

soln

A=(9,j)

x1=9,y1=j

B=(10,4)

x2=10,y2=4

slope=1

by using the fomulaof slope,

slope=y2-y1/x2-x1

1 =4-j/10-9

1 = 4-j/1

1=4-j

j=4-1

j=3

Answer:

j = 3

Step-by-step explanation:

(9 , j) ; [tex]x_{1}= 9[/tex]   and [tex]y_{1} = j[/tex]

(10, 4) ; [tex]x_{2} = 10[/tex]   and [tex]y_{2} = 4\\\\[/tex]

[tex]Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\ \frac{4 - j}{10-9} = 1\\\\\frac{4 - j}{1}=1[/tex]

4 - j = 1   {Subtract 4 from both sides}

-j = 1 -4

-j = -3 {Multiply both sides by (-1) }
