Answer:

a

  [tex]y' = 0.85 [/tex]

b

 [tex]P(J) = 0.27  [/tex]

c

 [tex]P(R) = 0.0144 [/tex]

d

  [tex]P(R') =  0.7744 [/tex]

e

 [tex]P(Q) =0.2256 [/tex]

Step-by-step explanation:

From the question we are told that

   The proportion of M & M's that is  brown is  b =  0.12

   The proportion of M & M's that is  yellow  is  y =  0.15

    The proportion of M & M's that is  red  is  r =  0.12

    The proportion of M & M's that is  blue  is  b =  0.23

    The proportion of M & M's that is  orange  is  o =  0.23

    The proportion of M & M's that is  green  is  g =  0.15

Generally the probability that a random selected M&M is not yellow is  

         [tex]y' =  1-y[/tex]

=>      [tex]y' =  1-0.15[/tex]

=>      [tex]y' = 0.85 [/tex]

Generally the probability that a randomly selected peanut M&M isgreen or red is mathematically represented as

       [tex]P(J) =  g +  r [/tex]

=>    [tex]P(J) =  0.15 + 0.12 [/tex]

=>    [tex]P(J) = 0.27  [/tex]

Generally the  probability that two randomly selected peanut M&M’s are both red is mathematically represented as

      [tex]P(R) = r^2[/tex]

=>    [tex]P(R) = 0.12^2[/tex]

=>    [tex]P(R) = 0.0144 [/tex]

Generally if two  two peanut M&M’s are selected the probability that neither of them are red is mathematically represented as

     [tex]P(R') =  (1 -r)^2[/tex]

=>  [tex]P(R') =  (1 - 0.12)^2[/tex]

=>   [tex]P(R') =  0.7744 [/tex]

Generally if two  two peanut M&M’s are selected the probability that at least one of them is red is mathematically represented as

        [tex]P(Q) =  1- P(R')[/tex]

=>      [tex]P(Q) =  1- 0.7744 [/tex]

=>      [tex]P(Q) =0.2256 [/tex]

Answer:

The probability is    [tex]P(Z) = 0.0064 [/tex]

Step-by-step explanation:

From the question we are told that

  The number of members is  n = 15

Generally the number of ways of selecting two member from the fifteen members is mathematically represented as

       [tex]K  =  ^{n}C_2 *  2![/tex]

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

      [tex]K  =  ^{15}C_2 *  2 * 1 [/tex]

=>  [tex]K  =  78  *  2 * 1 [/tex]

=>  [tex]K  =  156  [/tex]

Gnerally the number of outcome that matches the outcome required by the committee(Which is  reselecting the member who where the chairman and vice chairman of the board ) is   m =  1

Generally the probability of randomly selecting the two members who currently hold the positions of chairman and vice chairman and assigning them to their current positions is mathematically represented as

      [tex]P(Z) =  \frac{m}{K}[/tex]

=>    [tex]P(Z) =  \frac{1}{156}[/tex]

=>    [tex]P(Z) =  \frac{1}{156}[/tex]      

 =>    [tex]P(Z) = 0.0064 [/tex]      

Answer:

a

  The null hypothesis is  [tex]H_o : p = 0.67[/tex]

   The alternative hypothesis is  [tex]H_a : p \ne 0.67[/tex]

b

 The sample proportion is [tex]\^ p = 0.65[/tex]

Step-by-step explanation:

From the question we are told that

     The sample size is  n =  546  

      The number of people that use a laptop overnight is  [tex]k = 355[/tex]

    The population proportion is  [tex]p = \frac{2}{3} = 0.67[/tex]

   Generally

  The null hypothesis is  [tex]H_o : p = 0.67[/tex]

   The alternative hypothesis is  [tex]H_a : p \ne 0.67[/tex]

Gnerally the sample proportion is mathematically represented as

        [tex]\^ p = \frac{ k}{n}[/tex]

=>     [tex]\^ p = \frac{ 355}{546}[/tex]

=>     [tex]\^ p = 0.65[/tex]

Answer:

Step-by-step explanation:

If he uses 1 hour to practice harmonica, one our on homework, and another hour doing chores. He will be spending twice as much time practicing harmonica and doing homework than he would spend on chores.

Answer:

10 minutes more on working with his homework than his chores and harmonica OR 1/6 hour (or any other equivalent fraction).

Step-by-step explanation:

You can convert 1/4 into fifteen minutes. 15+15=30 minutes. Thus, he spends 30 minutes on his harmonica and doing chores.

You can convert 2/3 into 40 minutes.

40-30=10, so he spent 10 minutes more on working with his homework than his chores and harmonica.

Since you want it in fractions, you can find fractions that are equivalent to 10/60. One you can use is 1/6.

Answer:

The null hypothesis                 [tex]H_o : \mu = 3.2 \ mg/dl[/tex]

The alternative hypothesis      [tex]H_a : \mu > 3.2 \ mg/dl[/tex]

Step-by-step explanation:

From the question we are told that

  The mean is  [tex]\mu = 3.2 \ mg/dl[/tex]

   The standard deviation is [tex]\sigma = 1.5 mg/dl[/tex]

   The sample size is  n = 25

    The sample mean is  [tex]\= x = 3.75 \ mg /dl[/tex]

Generally

   The null hypothesis is : That the mean of the  Arsenic blood concentrations in healthy individuals is [tex]\mu = 3.2 \ mg/dl[/tex]

i.e

The null hypothesis  [tex]H_o : \mu = 3.2 \ mg/dl[/tex]

    The alternative hypothesis is : That the mean of the  Arsenic blood concentrations in healthy individuals is greater than  [tex]\mu = 3.2 \ mg/dl[/tex]

The alternative hypothesis      [tex]H_a : \mu > 3.2 \ mg/dl[/tex]

Answer:

its 148 because alternate

Answer: 148.

Step-by-step explanation:

Both angles are perpendicular, whilst being the same length and being a straight line. Therefore, it would be 148.

Answer:

The probability that, in any hour, less than 2 customers will arrive is 0.0067.

Step-by-step explanation:

The random variable X can be defined as the number of customers arriving hourly at the drive-through window at the Fidelity Credit Union.

The random variable X describes a finite number of occurrences of an event in a fixed time interval.

The random variable X follows a Poisson distribution with parameter λ = 7.1.

The probability mass function of X is:

[tex]P(X=x)=\frac{e^{-7.1}(7.1)^{x}}{x!};x=0,1,2,3...[/tex]

Compute the probability of less than 2 customers arriving as follows:

[tex]P(X<2)=P(X=0)+P(X=1)[/tex]

                [tex]=\frac{e^{-7.1}(7.1)^{0}}{0!}+\frac{e^{-7.1}(7.1)^{1}}{1!}\\\\=0.00083+0.00586\\\\=0.00669\\\\\approx 0.0067[/tex]

Thus, the probability that, in any hour, less than 2 customers will arrive is 0.0067.

Step-by-step explanation:

Answer:

There are two possible locations. E could be located in either -8 or 2.

Step-by-step explanation:

The number line is a one-dimensional graphing model for real numbers, in which each element is represented by points. Under this system, there are two directions:

[tex]-x[/tex] - Left semiaxis that corresponds to negative real numbers.

[tex]+x[/tex] - Right semiaxis that corresponds to positive real numbers.

Both semiaxis are divided by origin, which represents the real number zero.

Let E and F points on the number. If we know that [tex]F = -3[/tex] and [tex]EF = 5[/tex], there are two choices for the location of E. That is:

[tex]E_{1} = F+EF[/tex]

[tex]E_{1} = -3+5[/tex]

[tex]E_{1} = 2[/tex]

[tex]E_{2} = F-EF[/tex]

[tex]E_{2} = -3 -5[/tex]

[tex]E_{2} = -8[/tex]

There are two possible locations. E could be located in either -8 or 2.

Answer: 9

Step-by-step explanation:

I calculated it

Answer:

50°

Step-by-step explanation:

Angle NMP is an angle that has its vertex on a point along the circumference of the circle, thus, angle NMP is referred to as an inscribed angle of the circle.

The measure of an inscribed angle is equal to half of the measure of the arc it intercepts.

Therefore, the following equation shows the relationship between inscribed angle NMP and arc NP:

m<NMP = ½ × measure of arc NP

m<NMP = ½*100

m<NMP = 50°

Answer:

0.818335 ≤ p ≤ 0.86366

Step-by-step explanation:

Given that:

Sample size (n) = 1000

Positive lung cancer = 841

n(p) = 841, p(p) = 841/1000 = 0.841

n(1 - p) = 1000 - 841 = 159

1 - p = 0.159

95% confidence interval

For a 95% confidence interval : z = 1.96

P ± z√p(1-p) / n

0.841 ± 1.96 * √0.841(0.159) / 1000

0.841 - (1.96 * 0.0115636) = 0.818335344

0.841 + (1.96 * 0.0115636) = 0.863664656

0.818335 ≤ p ≤ 0.86366

Answer:

The equation for a is [tex]a=-\frac{2000}{7}*(t-g)[/tex]

The altitute is 101,428.57 feet

Step-by-step explanation:

You know that the relationship between ground temperature and atmospheric  temperature can be described by the formula

t = -0.0035a +g

where:

Solving the equation for a:

-0.0035a +g=t

-0.0035a= t - g

[tex]a=\frac{t-g}{-0.0035}[/tex]

[tex]a=-\frac{2000}{7}*(t-g)[/tex]

The equation for a is [tex]a=-\frac{2000}{7}*(t-g)[/tex]

If the atmospheric temperature is -305 °F and the ground temperature is 50 °F, then t= -305 °F and g= 50 °F

Replacing in the equation for a you get:

[tex]a=-\frac{2000}{7}*(-305-50)[/tex]

[tex]a=-\frac{2000}{7}*(-355)[/tex]

a= 101,428.57

The altitute is 101,428.57 feet
