The total number of possibilities for four digit pin with the condition of no digit is repeated is equal to 5040.

Total number of digit used to form pin = 4

Condition is : No digit is repeated.

Number of digits are :

( 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 )

Total digits are = 10

Number of possibilities to form four digit pin with no digit repeated

=  ¹⁰P₄

= ( 10! ) / ( 10 - 4 )!

= ( 10 × 9 × 8 × 7 × 6! ) / 6!

= 10 × 9 × 8 × 7

= 5040

Therefore, the total number of possibilities to form four digit pin with the given condition is equal to 5040.

Step-by-step explanation:

The maximum amount of water that the pool can hold is 1000 cubic feet.

To find the maximum amount of water that the rectangular prism swimming pool can hold, we need to calculate its volume.

The volume of a rectangular prism is given by:

V = l x w x h

where l is the length, w is the width, and h is the height of the prism.

Given the dimensions of the swimming pool, we have:

l = 16 feet

w = 12.5 feet

h = 5 feet

Therefore, the volume of the swimming pool is:

V = l x w x h

V = 16 feet x 12.5 feet x 5 feet

V = 1000 cubic feet

The number of oranges that are expected to weigh more than 4 oz is:

1400 - (1400 × 0.0228)≈ 1368.

The mean weight of the oranges growing in an orchard is 8 oz and standard deviation is 2 oz, the distribution of the weight of oranges can be represented as normal distribution.

From the batch of 1400 oranges, the number of oranges is expected to weigh more than 4 oz can be found using the formula for the Z-score of a given data point.

\(z = (x - μ) / σ\)

Wherez is the Z-score of the given data point x is the data point

μ is the mean weight of the oranges

σ is the standard deviation

Now, let's plug in the given values.

\(z = (4 - 8) / 2= -2\)

The area under the standard normal distribution curve to the left of a Z-score of -2 can be found using the standard normal distribution table. It is 0.0228. This means that 0.0228 of the oranges in the batch are expected to weigh less than 4 oz.

Answer:

The correct answers are the following:

A) P=12n-275

B) 124

C) Decrease by $100

Step-by-step explanation:

A) P=12n-275 - Each person (n) pays $12, then the cost/expense ($275) is subtracted from the income to get the profit.

B) 1,213=12n-275  - Plug in the value for P ($1,213).

1,488=12n  - Add $275 to both sides.

124=n  - Divide both sides by $12.

n=124 - This the number (n) of people that attended.

C) P=12n-375 - Change the value for expense to $375.

P=12(124)-375  - Plug in the value for n (124).

P=1488-375  - Simplify and find the difference.

P=1,113 - This is your profit.

1,113-1,213=-100 - $100 reduction/decrease of profit (or -$100 to profit)

Therefore, Alvin's average paddling rate for a canoe trip to a campsite was 6 km/hr

Let's find out Alvin's average paddling rate for a canoe trip to a campsite.The distance Alvin paddled on the way to the campsite is the same as on the way back since he travelled to the same place and back to his initial location.

The rate at which Alvin paddled to the campsite is given by the relation;

r - 3 = (total distance)/(time taken to get to the campsite).

Where r is Alvin's average paddling rate, 3 is the speed of the river current, the total distance is D, and the time taken to get to the campsite is 9 hours.

On the way back, Alvin's rate of paddling is given by;

r + 3 = (total distance)/(time taken to get back from the campsite).

Where r is Alvin's average paddling rate, 3 is the speed of the river current, the total distance is D, and the time taken to get back from the campsite is 4 hours.Since the distance Alvin paddled to and from the campsite is the same, we can use D = rt.

Therefore, we can get an equation in r only:

r - 3 = D/9(r) + 3

r= D/4

Now, we need to solve for D. We can do this by setting both expressions equal to each other. That is:

r - 3 = r + 3D/9

r-3 = D/4(4)D/9

r-3= D/4

Multiplying both sides by 36 gives:

4D = 9D/4 * 36D

D= 81 km

Therefore, the distance of the campsite is 81 km.

Using D = rt,

we can find the average paddling rate r:

r = D/t

r = 81/(9 + 4) r

r = 6 km/hr.

Answer:

5

Step-by-step explanation:

We know that a^2+b^2=c^2 from the Pythagorean theorem   where a and b are the legs and c is the hypotenuse

4^2+3^2 = c^2

16+9 = c^2

25 = c^2

Taking the square root of each side

sqrt(25) = sqrt(c^2)

5 =c

Answer:

d = 5 m

Step-by-step explanation:

The diagonal divides the rectangle into 2 right triangles with legs 3 and 4 and hypotenuse h

Using Pythagoras' identity in one of the right triangles, then

d² = 3² + 4² = 9 + 16 = 25 ( take the square root of both sides )

d = \(\sqrt{25}\) = 5

The meaure of the side length x of the right triangle is approximately 2.02 units.

The figure in the image is a right triangle with one of its internal angle at 90 degrees.

From the image:

Angle θ = 68 degree

Adjacent to angle θ = x

Opposite to angle θ = 5

To solve for the missing side length x, we use the trigonometric ratio.

Note that: tangent = opposite / adjacent

Hence:

tan( θ ) = opposite / adjacent

Plug in the given values and solve for x.

tan( 68° ) = 5 / x

Cross multiply:

tan( 68° ) × x = 5

x = 5 / tan( 68° )

x = 2.02

Therefore, the value of x is 2.02.

Step-by-step explanation:

the median is the middle value of the data sey. If there is no exact middle then it is the average of the values either side of the middle.

listing the values from the data set

1 , 1 , 2, 3 ,  4 , 4 , 4 , 5

               ↑ middle

median = (3 + 4) ÷ 2 = 7 ÷ 2 = 3.5

The exact value of cos^-1( √3/2) = 30°

The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.

There are special angles in trigonometry, this angles have exact value and can be obtained without using calculator. Examples of this calculator are; 30°, 60°, 45°

sin30 = 1/2

cos 30 = √3/2

tan 30 = 1/√3

cos 60 = 1/2

sin 60 = √3/2

tan 60 = √3

Therefore, if cos^-1( √3/2) = x

cos x = √3/2

cos 30 = √3/2

cos x = cos 30

therefore x = 30

Here is my answer. I hope this is helpful.

The angle measured is 70°.

A tangent at any point of a circle is perpendicular to the radius of the circle through the point of contact.

So, the two angles made by the tangent and the point of contact of the circle tangent will be equal to 90°

Since the sum of the angles in a quadrilateral is 360°.

Therefore, 110°+90°+90°+x°= 360°

Thus, x°=70°

Hence the missing angle is 70°.

To calculate the probability of a type II error, we need to first determine the critical value for the test. This can be found using the formula:

Critical value = mean + (z-score for desired level of significance) x (standard deviation/square root of sample size)

Assuming a 5% level of significance and a sample size of 25, the z-score for a one-tailed test is 1.645. Plugging in the values, we get:

Critical value = 100 + (1.645) x (5/sqrt(25)) = 101.645

Next, we need to determine the probability of failing to reject the null hypothesis (i.e. making a type II error) when the true mean heat evolved is actually 103. This can be found using a normal distribution table or calculator:

z-score = (critical value - true mean)/standard deviation = (101.645 - 103)/5 = -0.31

Using the normal distribution table, the probability of a z-score of -0.31 or less is 0.3783. Therefore, the probability of making a type II error is approximately 38%.

In summary, if the true mean heat evolved is 103 and we are using a one-tailed test with a 5% level of significance and a sample size of 25, there is a 38% chance that we will fail to reject the null hypothesis and make a type II error.

If the measure of angle 1 is 50° then the measure of angle 2 is 30°.

We know that line l ∥ line m and line p is the transversal.

Let's label the diagram as follows.

Now, by the vertically opposite angles theorem,

we have angle 1 = ∠TPQ = 50°

now ∠P and ∠Q form interior angles,

Hence, by the interior angles theorem, we have

∠P + ∠Q = 180°

The sum of the interior angles of the angles formed by the transversal is 180°.

50° + ∠Q = 180°

subtracting 50° on both sides we get,

∠Q = 180° - 50°

∠Q = 30°

Hence, the measure of angle 2 is 30°.
