Answer:

Reject H0 as the critical region for alpha = 0.07 is  z ≤ -1.82  and z≥ 1.82

Step-by-step explanation:

For the significance level ∝ = 0.07

For a two tailed test we divide it with 2 and get 0.035

When we subtract 0.035 from 1 we get 0.965

And when we look at the z- table and corresponding to 0.965 we find the value of z to be 1.82

Now the calculated value of z=  -1.94 which is less than ±1.82.

Hence reject H0 if z ≤ -1.82  and z≥ 1.82

Therefore reject H0.

While ∝ =0.07

p- value = 0.06 should be examined

the p- value is the smallest value of ∝ where we reject H0.

Hence at ∝= 0.06  critical region is  z ≤ -1.88  and z≥ 1.88

At ∝= 0.05  critical region is  z ≤ -1.96  and z≥ 1.96

So p- value is near 0.06

Step-by-step explanation:

Natural numbers or the counting numbers is all the positive, non-decimal numbers. They are 1, 2, 3... and so on. Natural numbers does not include 0.

Whole numbers are all the natural numbers with the addition of 0. In other words, whole numbers are: 0, 1, 2, 3... and so on.

Therefore, the only number that is a whole number and that's not a natural number is 0.

Answer: 0

Step-by-step explanation: The set of counting numbers, {1, 2, 3, 4, ...}

is called the set of natural numbers.

When we include 0 in the set of natural numbers,

the new set, {0, 1, 2, 3, ...} is called the set of whole numbers.

Notice that all natural numbers are

included within the set of whole numbers.

We can represent the relationship between these two

sets of numbers using the diagram shown below.

In fact, 0 is the only whole number that's not a natural number.

In the roll of a pair of fair dice, The sample space is as follows:

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

If x,y represent  the  possible outcome of rolling the two die

Then the total number of possibilities for  the sample space = (x,y)

= (6 × 6) = 36

Now, the probability of getting a sum of 1 does not exist in the roll of a pair of  fair dice.

Therefore, Probability(1) = 0

The total number of children who attended play is 10 and this can be determined by forming the linear equation in two variables.

Given :

The following steps can be used in order to determine the total number of children attending play:

Step 1 - Let the total number of adults attending play be 'x' and the total number of children attending play be 'y'.

Step 2 - The linear equation that represents the total number of people attending the play is:

x + y = 40

x = 40 - y    --- (1)

Step 3 - The linear equation that represents the price of all the tickets is:

12x + 8y = 440    --- (2)

Step 4 - Now, substitute the value of 'x' in the above expression.

12(40 - y) + 8y = 440

Step 5 - Simplify the above expression.

480 - 12y + 8y = 440

40 = 4y

y = 10

Answer:

55mph

None of the option is correct

Step-by-step explanation:

Let v be the speed and t as the time taken. If speed varies inversely as the time it takes to drive, then v ∝ 1/t.

v = k/t where k is the constant of proportionality.

IF it takes Kris 5 hours when driving at 55 mph, then v = 55mph when t = 5 hours.

Substituting this values into the formula above;

55 = k/5

k = 55*5

k = 275mp/hr²

To calculate the speed it will Martin to  drive for 5 hours, we will substitute k = 275 and t = 5 into the original equation v = k/t

v = 275/5

v = 55 mph

Hence, martin will also need to drive at 55mph to take 5 hours

discrete probability distribution

Step-by-step explanation:

A discrete probability distribution is a term that describes a form of a probability distribution that is used in a situation where the set of possible outcomes is discrete.

While it also has a tendency to take on a countable number of values, it is a probability distribution where a sample is drawn from a larger population, this sample points possess an empirical distribution that is considered to be discrete, which resulted in information about the population distribution.

Hence, given that Bob is dealing with discrete data and the samples are drawn without replacement, the likely probability distribution is DISCRETE PROBABILITY DISTRIBUTION

D) X′ (0, 6), Y′ (0, 0), Z′ (15, 0)

Step-by-step explanation:

From the image attached, given that the location of the triangle is at:

X(0, 2). Y(0, 0), Z(5, 0)

Transformation is the movement of a point from its initial position to a new position. A shape is transformed by transforming all the points in the shape. Types of transformations are reflection, rotation, dilation and translation.

A dilation produces the same shape but different size. If the dilation < 1, then it is a reduction but if dilation > 0 then it is an enlargement.

A point A(x, y) which is dilated by a factor of c at the origin has new coordinates at A'(cx, cy).

Since triangle XYZ is dilated by a factor of 3 with the center of dilation at the origin, this represents an enlargement and the new coordinates of the triangle are:

X'(3*0, 3*2) = X'(0, 6)

Y'(3*0, 3*0) = Y'(0, 0)

Z'(3*5, 3*0) = X'(15, 0)

Answer:

The  revenue is [tex]R(9) = \$ 876.9[/tex]

Step-by-step explanation:

From the question we are told that

  The  rate of change  in revenue for Under Armour from 2004 through 2009 is  

   [tex]\frac{d R }{dt } = 13.897t + \frac{284.653}{t}[/tex]

Now  

     [tex]dR = (13.897t + \frac{284.653}{t})dt[/tex]

Integrating both sides to obtain R(t)

     [tex]\int\limits dR = \int\limits (13.897t + \frac{284.653}{t})dt[/tex]

    [tex]\int\limits dR = \int\limits (13.897\frac{t^2}{2} + 284.653(ln (t)) ) + C[/tex]

From the question we have that at  t  = 8  [tex]R(8)= \$ 725.2 \ million[/tex]

   [tex]725.2 = 6.9485(8)^2 + 284.653(ln (8) ) + C[/tex]

So

At  t = 9  

   [tex]R(9) = 6.9485*(9)^2 + 284.653(ln (9) ) -311.4[/tex]

Sampling methods are used to choose members from the population to be a part of a study.

There are different kinds of sampling methods used in different scenarios like simple random sample, stratified random sample, systematic random sample and cluster random sample.

There are also methods like voluntary response and convenience sample which are not that effective.

Voluntary response sample is a method of sampling by which researcher requests to members of a population to take part in the sample and the member decides to whether join or not to join in the sample.

Given study is an internet poll where the researches asks people to indicate whether or not they have a cable subscription. 1974 people responded to the poll fully on their consent.

the probability that more than 70% of customers in the sample will need additional maintenance is 0.0371

Step-by-step explanation:

From the information given:

we are to determine the probability that more than 70% of customers in the sample will need additional maintenance

In order to achieve that, let X be the random variable that follows a binomial distribution.

Then X [tex]\sim[/tex] Bin(48, 0.6)

However 70% of 48 samples is

= 0.7 × 48 = 33.6 [tex]\simeq[/tex] 34
