The percentage of the cases in a normal distribution falls between 35 and 45 is  0.6826. ii)  If you go out 3 standard deviations from the mean on both sides you capture is 0.9974.

An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically towards either extreme. The distribution's mean is another name for the centre of the range.

A Gaussian distribution or probability bell curve are other names for the normal distribution. Since it is symmetric about the mean, it shows that values close to the mean happen more frequently than those distant from the mean.

P[35 < x < 45]

= p [ 35 - 40/5 < x - 40 / 5 < 45 - 205]

Using the z-table we have:

= 2(0.8413 - 1)

= 0.6826

For 3 standard deviations from mean:

P [-35 < x - m < 35]

= P[-3 < x - m / SD < 3]

Using the z-table:

P[-3 < x - m / SD < 3] = 2(0.9987) - 1

= 0.9974

Hence, the percentage of the cases in a normal distribution falls between 35 and 45 is  0.6826. ii)  If you go out 3 standard deviations from the mean on both sides of a normal distribution percentage of the cases will you capture is 0.9974.

The number 8 is a rational number.

Step-by-step explanation:

That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The number 8 is a rational number because it can be written as the fraction 8/1. Likewise, 3/4 is a rational number because it can be written as a fraction.

The distance between your house and school is 4.1 miles.

According to the given question.

Point c represents your house.

Point d represents post office which is directly west to the point c i.e from house.

And point e represents school which is west of the post office.

Also, it is given that the distance between house and post office, cd is 1.7 miles.

And the distance between the post office and school,de is 2.4 miles.

Now, if we see the attached figure we can say that

cd + de = ce

⇒ 1.7miles  + 2.4miles  = 4.1 miles

Hence, the distance between your house and school is 4.1 miles.

Using a linear function, the total charge from parking in the lot for 72 hours is of:

b. $146.

A linear function is modeled by:

y = mx + b

In which:

Both the basic fee, which is the y-intercept, and the hourly fee, which is the slope, are of $2, hence the cost of parking x hours is given by:

C(x) = 2x + 2

Hence the cost for parking 72 hours is:

C(72) = 2 x 72 + 2 = 2 x 73 = $146.

Which means that option b is correct.

The penny will fall from distance of 232 feet during the 8th second only, as it falls 960 feet in the first 8 seconds, but 728 feet in the first 8 seconds.

The distance the penny falls each second is increasing by 32 feet (16 feet + 32 feet = 48 feet, 48 feet + 32 feet = 80 feet, and so on). Therefore, during the 8th second, the distance it will fall is:

16 + 48 + 80 + ... + (8 - 1) * 32 feet

Using the formula for the sum of an arithmetic sequence, we get:

(8 / 2) * (16 + (8 - 1) * 32) feet

= 4 * (16 + 7 * 32) feet

= 4 * 240 feet

= 960 feet

So the penny will fall 960 feet during the first 8 seconds. However, we need to subtract the distance it fell during the first 7 seconds to find the distance it fell during the 8th second only. The total distance it fell during the first 7 seconds is:

16 + 48 + 80 + ... + (7 - 1) * 32 feet

= (7 / 2) * (16 + (7 - 1) * 32) feet

= 3.5 * (16 + 6 * 32) feet

= 3.5 * 208 feet

= 728 feet

Therefore, the penny will fall 960 - 728 = 232 feet during the 8th second only.

Answer:

(f-g)(x)=-x^(2)+2x+8

the solutions are:

x=4 or x=-2

Step-by-step explanation:

(f-g)(x)=2x+1-(x^(2)-7)

(f-g)(x)=-x^(2)+2x+1+7

(f-g)(x)=-x^(2)+2x+8

does this help or should I solve for the zeros/solutions of this quadratic equation?

then:

-x^(2)+2x+8=0

-(x^(2)-2x-8)=0

x^(2)-2x-8=0

(x-4)(x+2)=0

x=4 or x=-2

Answer:

The required answer is: -x^2+2x+8

Step-by-step explanation:

We have been given the two function:

f(x)=2x+1

And g(x)=x^2-7

We have to find (f-g)(x):

(f-g)(x)=f(x)-g(x)

(2x+1)-(x^2-7)

2x+1-x^2+7

-x^2+2x+8

Hence, the required answer is: -x^2+2x+8

Step-by-step explanation:

The triangle is isosceles. The measure of the two internal angles J and K are equal; The misure of the external K angle (2) is half a circle minus the internal K (1). The internal angle in R is calculated by difference between 180 and twice the internal K angle (1).

1. 72° as well.

2. 180-70-70 = 40°

3. \(m\angle2 = 110 \rightarrow m\angle1 =70\), Same as #2: 40°

4. \(x+2x+2x = 180 \rightarrow 5x=180 \righarrow x= 36\)

5. \(x +(x+30)+(x+30) = 180 \rightarrow 3x +60 = 180 \rightarrow 3x= 120 \rightarrow x=40\)

Answer:

13.5

Step-by-step explanation:

We can solve for x using the side splitter theorem, assuming that the two triangles' bases are parallel.

\(\dfrac{\text{segment of left side}}{\text{left side}} = \dfrac{\text{segment of right side}}{\text{right side}}\)

↓ plugging in the lengths given in the diagram

\(\dfrac{4}{4 + 5} = \dfrac{6}{x}\)

     \(\dfrac{4}{9} = \dfrac{6}{x}\)

↓ cross-multiplying

\(4x = 9(6)\)

\(4x = 54\)

↓ dividing both sides by 4

\(x = 13.5\)

Answer:

Step-by-step explanation:

i just did the test

The problem describes a scenario in which two objects, A and B, start moving towards each other from different locations and speeds. Object A starts from point A, which is 60 miles away from object B, at a speed of 20 mph, while object B starts from point B at a speed of 25 mph.

To solve this problem, we can use the formula Distance = Speed x Time. We know that the total distance between A and B is 60 miles and we want to find the time at which they meet. Let's call that time "t". Let's also assume that they meet at some point "x" miles away from A. Then, the distance that A travels is 60 - x and the distance that B travels is x. Using the formula, we can set up an equation:

Distance A + Distance B = Total Distance

(60 - x) + x = 60

Simplifying this equation, we get:

60 - x + x = 60

60 = 60

This equation is always true, so it doesn't give us any information about when A and B will meet. However, we can use the formula Distance = Speed x Time to set up another equation that relates the distance and speeds of A and B to the time they travel before meeting:

Distance A = Speed A x Time

Distance B = Speed B x Time

Substituting the distances and speeds we know, we get:

(60 - x) = 20t

x = 25t

We can use either equation to solve for t, but let's use the second equation. Substituting x = 25t, we get:

(60 - 25t) = 20t

Simplifying and solving for t, we get:

60 = 45t

t = 4/3

Therefore, A and B will meet after traveling for 4/3 hours, or 1 hour and 20 minutes.
