A. 0.125

Step-by-step explanation:

Answer:

0.19146

0.066807

Step-by-step explanation:

Given that :

Mean (m) = 70

Standard deviation (s) = 10

a. Find the probability that a randomly selected high school senior will have a score between 70 and 75.

X ≤ 70 :

Using : z = (x - m) / s

Z = (70 - 70) / 10

Z = 0 / 10

Z = 0

P( Z < 70) = 0.500

X ≤ 75

z = (x - m) / s

Z = (75 - 70) / 10

Z = 5 / 10

Z = 0. 5

P(z < 0.5) = 0.69146

0.69146 - 0.5000

= 0.19146

b. Find the probability that a randomly selected high school senior will have a score higher than 85.

X ≥ 85

z = (x - m) / s

Z = (85 - 70) / 10

Z = 15 / 10

Z = 1.5

P(z > 1.5) = 0.066807 ( Z probability calculator)

Answer:

[tex]2^{100} * 6[/tex]

Step-by-step explanation:

length of finite strings = 100

number of letters : 4 { a,b,c,d }

Determine the number of strings that use ≤ two different letters

since the number of letters is 4 and we are allowed to make use of at most 2 different letters

Then the number of ways will be : [tex]^{4} C_{2}[/tex] = 6 ways

now considering the length of the Finite strings

The number of strings that use no more than two different letters

= [tex]2^{100} * 6 ways[/tex]

Answer:

The probability that all three of them will find full-time jobs within three months after graduation from college is 0.0197.

Step-by-step explanation:

Let X denote the number of college graduates who will find a full time job within three months after graduation from college.

A random sample of 3 college students, who will be graduating soon, are selected.

The probability of X is, p = 0.27.

Each student is independent of the other to find a full time job within three months after graduation from college.

The random variable X follows a binomial distribution with parameter n = 3 and p = 0.27.

Compute the probability that all three of them will find full-time jobs within three months after graduation from college as follows:

[tex]P(X=3)={3\choose 3}(0.27)^{3}(-0.27)^{3-3}[/tex]

                [tex]=1\times 0.019683\times 1\\=0.0197[/tex]

Thus, the probability that all three of them will find full-time jobs within three months after graduation from college is 0.0197.

Answer:

30

Step-by-step explanation:

Plug in -4 wherever you see an x. So:

([tex]-4^{2}[/tex])-(3*-4)+2 --> (16) - (-12) + 2 --> 16 + 12 +2 (two negatives make a positive) --> 28 + 2 = 30

Answer:

81cm^2

Step-by-step explanation:

Answer:

81

Step-by-step explanation:

Let's do a quick refresher on how to find area.

l = length

w = width

a = area

a = l(w)

Since one side is 9cm, and all the sides are equal, you multiply 9x9.

Nine times nine is 81.

Answer:

Step-by-step explanation:

Answer:

a

 [tex]P(K) = 0[/tex]

b

 [tex]P(Z) = 0[/tex]

c

[tex]P(W) = 0.1016[/tex]

d

 [tex]P(R) = 0.29[/tex]

Step-by-step explanation:

From the question we are told that

  The number of married people is  k = 15  

   The number of people that are not married is  u =  15

   The number of people selected is  e = 12

   The total number of people is n  =  30

Generally the number of ways of  selecting 12  people from the married people is mathematically represented as

        [tex]B = ^k C_e[/tex]

Here C stands for combination hence we will be making use of the combination functionality in our calculators

       [tex]B = ^{15} C_{12}[/tex]

=>   [tex]B = 455[/tex]

Generally the number of ways of  selecting 0  people from the not  married people is mathematically represented as

    [tex]A = ^u C_0[/tex]

=> [tex]A = ^{15} C_0[/tex]

=> [tex]A = 1[/tex]

Generally the number of ways of  selecting 12  people from the total number of  people is mathematically represented as

     [tex]D = ^{n} C_{12}[/tex]

=> [tex]D = ^{30} C_{12}[/tex]

=> [tex]D = 8.6493225 *10^{7}[/tex]

Generally the number of ways of selecting 12 people from the married people is equal to the number of ways of selecting 12 people from not married, also  the number of ways of selecting 0  people from the not married is equal to the number of ways of selecting 0 people from the married people,   all this is because the number of married people  is equal to the number of not married people

Generally the number of ways of selecting 8 people from the married people is  

      [tex]E = ^{k} C_{8}[/tex]

=>   [tex]E = ^{15} C_{8}[/tex]

=>   [tex]E =6435[/tex]

Generally the number of ways of selecting 4 people from the not  married people is  

       [tex]F = ^{u} C_{4}[/tex]

=>   [tex]F= ^{15} C_{4}[/tex]

=>   [tex]F=1365[/tex]

Generally the number of ways of selecting 6 people from the   married people is  

       [tex]G = ^{k} C_{6[/tex]

=>   [tex]G= ^{15} C_{6}[/tex]

=>   [tex]G=5005[/tex]

Generally the number of ways of electing 6 people from the married people is equal to the number of ways of selecting 6  people from the not married people

Generally the probability that the jury consists of all married people is mathematically represented as

        [tex]P(K) = \frac{455 * 1 }{8.6493225 *10^{7}}[/tex]

=>     [tex]P(K) = \frac{455 * 1 }{8.6493225 *10^{7}}[/tex]

=>     [tex]P(K) = 0.000005[/tex]

=>    [tex]P(K) = 0[/tex]

Generally the probability that the jury consists of all not married people  is mathematically represented as

        [tex]P(Z) = \frac{455 * 1 }{8.6493225 *10^{7}}[/tex]

=>     [tex]P(Z) = \frac{455 * 1 }{8.6493225 *10^{7}}[/tex]

=>     [tex]P(Z) = 0.000005[/tex]

=>    [tex]P(Z) = 0[/tex]

Generally the probability that the jury consists of 8 married and 4 that are not married is mathematically represented as

     [tex]P(W) = \frac{ E * F}{D}[/tex]

=>  [tex]P(W) = \frac{ 6435 * 1365}{8.6493225 *10^{7}}[/tex]

=>  [tex]P(W) = 0.1016[/tex]

Generally the probability that the jury consists of 6 married and 6 that are not married. is mathematically represented as

 [tex]P(R) = \frac{G * G}{D}[/tex]

  [tex]P(R) = \frac{5005 * 5005}{8.6493225 *10^{7}}[/tex]

=> [tex]P(R) = 0.29[/tex]

The answer is 47.

The remainder when p(x) is divided by (x-3) is 1

The remainder of a polynomial can be gotten from graphs and by using the remainder theorem

The divisor of an expression is the number or expression that divides an expression

The divisor of the polynomial is given as:

x - 3

Set the above divisor to 0

[tex]x - 3 = 0[/tex]

Add 3 to both sides of the equation

[tex]x = 3[/tex]

Next, we determine P(3) from the graph.

From the graph, we have:

[tex]P(3) = 1[/tex]

Hence, the remainder is 1

Answer:

Step-by-step explanation:

Answer:

y = - (1/2) x + 1

Step-by-step explanation:

The given equation of the line is:

2 x - y - 7 = 0

solving for y gives:

2 x - 7 = y

so y = 2 x - 7

where the slope is "2", which is fundamental to know in order to construct a perpendicular line to it by using the "opposite of the reciprocal" of the given slope.

So in our case, the slope of the perpendicular line must be:  "- 1 / 2"  (negative one half).

now we can build the equation of the new line, using this slope and requesting the point (4, -1) to be in it:

y = - (1/2) x + b

-1 = - (1/2) (4) + b

-1 = - 2 + b

solve for b:

b = 2 - 1 = 1

Then the equation of the perpendicular line is:

y = - (1/2) x + 1

y= -1/2 x+1

Step-by-step explanation:

2x-y-7=0

2x-7=y

y=2x-7

Answer:

5.5 gallons

Step-by-step explanation:

The answer is 5.5 gallons.

Number of containers = 14

Amount in each container = 1.5 liter

1 gallon = 3.8 liter

Total amount of tea in gallon

Total amount of tea in gallon = Number of containers × Amount in each container / 3.8

Total amount of tea in gallon = 14 × 1.5 / 3.8

Total amount of tea in gallon = 21 / 3.8

Total amount of tea in gallon = 5.5 liter (Approx.)
