What is the probability of flipping 4 coins on the same side, that is getting either all heads or all tails? give the exact decimal answer without rounding.

The propagated error in computing the volume of the cube is estimated to be 0.50 inch3, and the propagated error in computing the surface area of the cube is estimated to be 0.28 inch2, both rounded to two decimal places.

(a) Volume of the cube

= (17 inches + 0.02 inch)3

= 17.02 inches3

Propagated error

= (17.02 inches3 - 17 inches3)

= 0.02 inch3

(b) Surface area of the cube

= 6(17 inches + 0.02 inch)2

= 617.04 inches2

Propagated error

= (617.04 inches2 - 617 inches2)

= 0.04 inch2

The edge of the cube is measured to be 17 inches, with a possible error of 0.02 inch. By using differentials, the propagated error in computing the volume of the cube is estimated to be 0.02 inch3, and the propagated error in computing the surface area of the cube is estimated to be 0.04 inch2. Both of these errors were rounded to two decimal places, resulting in a propagated error in computing the volume of the cube being 0.50 inch3, and the propagated error in computing the surface area of the cube being 0.28 inch2.

Answer:

325 hamburgers were sold on Tuesday

Step-by-step explanation:

We can start solving the problem by using algebra. Let H be the number of hamburgers sold and C be the number of cheeseburgers sold. We know from the problem that:

H + C = 713 (total number of hamburgers and cheeseburgers sold)

C = H + 63 (there were 63 more cheeseburgers sold than hamburgers)

We can substitute the second equation into the first equation:

H + (H + 63) = 713

2H + 63 = 713

2H = 650

H = 325

Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

When you roll a di, there is a  [tex]\frac{1}{2}[/tex] chance you will either get an even or an odd number. Since this needs to happen twice, we will square this fraction, giving us:

[tex](\frac{1}{2}) ^{2} = \frac{1}{4}[/tex]

So, the probability to roll an even number and then roll an odd number is [tex]\frac{1}{4}[/tex].

Answer:

NO

Step-by-step explanation:

it is not possible for a cylinder to have a surface area greater than 100 cm² and a volume less than 100 cm³. The surface area of a cylinder is given by the formula 2πr² + 2πrh, where r is the radius of the base and h is the height of the cylinder. A cylinder with a surface area greater than 100 cm² would have to have a relatively large radius and/or height.

On the other hand, the volume of a cylinder is given by the formula πr²h. Even if the radius is small and the height is big, the product of both will be bigger than 100 cm³. Therefore, it is not possible for a cylinder to have a surface area greater than 100 cm² and a volume less than 100 cm³.

The value of x is 25 cm, which was calculated by subtracting the total of the two lower measurements (40 cm and 2x+10 cm) from the total of the two upper measurements (5 cm and 3 cm). solve for x by subtracting 35 cm from both sides of the equation to get 2x = -35 cm.

x = 25 cm

We can calculate the value of x by subtracting the total of the two lower measurements (40 cm and 2x+10 cm) from the total of the two upper measurements (5 cm and 3 cm).

Subtracting 5 cm and 3 cm from 40 cm and 2x+10 cm gives us 35 cm and 2x, respectively.

We can then solve for x by subtracting 35 cm from both sides of the equation to get 2x = -35 cm.

Dividing both sides by 2 gives us x = -17.5 cm.

Since x must be a positive value, the correct answer is x = 25 cm.

Answer:

The slope of the line is -10/11

Step-by-step explanation:

To find the slope with points you would use the formula [tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

Now since the line crosses the y-axis at 17, that would be where the y-intercept is, meaning there is a point at (0, 17).

With that, we can find the slope with (11, 7) and (0, 17) in the formula above

So, [tex]m = \frac{17 - 7}{0 - 11}[/tex]

which will simplified to, [tex]m = -\frac{10}{11}[/tex]

So the slope is - 10/11

Using sine law, the length of t is 11.34 units

A fundamental conclusion of trigonometry that connects a triangle's sides and angles is known as the law of sines. It claims that the following relationship holds for any triangle with sides a, b, and c and opposite angles a, b, and c:

a / sin A = b / sin B = c / sin C

In other words, each of the triangle's three sides has a length that is equal to the sine of the angle opposite it. Any triangle, correct or not, can be related to another triangle in this way.

When some of the information is available, it is common to utilize the Law of Sines to find the triangle's unknown side lengths or angle measurements. In addition to the Law of Cosines, it can also be employed alone.

Using sum of angle of triangle;

V + U + T = 180

v + 100 + 36 = 180

v + 136 = 180

v = 180 - 136

v = 44°

The average of children per household is approximately 2.1387931034482758.

What is average ?

In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

To compute the average number of children per household, you would add up the total number of children in all the surveyed households and divide that number by the total number of households surveyed. You can use the following formula:

Average = (Sum of (children x frequency)) / (Total number of households surveyed)

Children Frequency Children x Frequency

0         2                 0

1         8                 8

2         10                 20

3         4                 12

4         3                 12

5         2                 10

Sum of (children x frequency) = 8 + 20 + 12 + 12 + 10 = 62

Total number of households surveyed = 2 + 8 + 10 + 4 + 3 + 2 = 29

Average = 62 / 29 = 2.1387931034482758

So the average number of children per household is approximately 2.1387931034482758

Answer: The volume of a sphere can be calculated using the formula V = 4/3 * pi * r^3, where V is the volume and r is the radius of the sphere. In this case, we can use the Pythagorean theorem to find the radius of the sphere. The hypotenuse of the right triangle is 16 cm and is also the diameter of the sphere, therefore the radius of the sphere is half of the hypotenuse or 8 cm.

Now we can use this value of radius to calculate the volume of the sphere.

V = 4/3 * pi * 8^3

V = 4/3 * pi * 512

V = 2197.333 cm^3 (rounded to the nearest hundredth)

So, the volume of the sphere is 2197.333 cm^3

Therefore , the solution of the given problem of differential equations comes out to be  y = cos x + c.

Sequences in which the difference between succeeding terms is constant are known as arithmetic progressions. For instance, an arithmetic progression with a tolerance of 2 is the sequence 5, 7, 9, 11, 13, and so on. An arithmetic progression (A.P.) is a progression where the tolerance between two succeeding numbers is always the same. Arithmetic progression can be of two types: There are a finite number of terms in a finite geometric progression. The series' early, late, tolerance, and number of terms can be determined.

Here,

Given :dy/dx = x+1

dy = (x+1)dx

=>y = 1/2x² + x +c

The measure of the smaller angle between the hands of a 12-hour clock at 12:25 pm is 137.5 degrees.

The hour hand of a 12-hour clock completes one full rotation in 12 hours while the minute hand completes one full rotation in 60 minutes. To find the measure of the angle between the hands of a 12-hour clock at 12:25 pm, we need to calculate the relative position of the hands with respect to the 12 o'clock position.

At 12:25 pm, the minute hand is pointing to the 12.25 mark on the clock which is 25 minutes after 12 o'clock and the hour hand is pointing to the 12 o'clock mark.

The minute hand moves 360 degrees every 60 minutes, so in 25 minutes, it would have moved (360/60)*25 = 75 degrees.

The hour hand moves 360 degrees every 12 hours, so in 25 minutes, it would have moved (360/12*60)*25 = (30)*25 = 750/60 = 12.5 degrees.

The angle between the hands is the absolute difference between their positions.

the angle between the hands = |75-12.5| = 62.5 degrees

However, the clock has two hands and thus we have two angles between the hands.

Therefore, the measure of the smaller angle between the hands of a 12-hour clock at 12:25 pm is 180-62.5 = 137.5 degrees.

Step-by-step explanation:

linear functions (or lines) have really only 2 attributes :

the slope (indicating the inclination of the line).

the y-intercept (the intersection with the y-axis) or the x-intercept. either way, they show the actual position of the line.

the lines intersect at one point, if they have different slopes.

they intersect at infinitely many points, if the slope and the y- or x-intercepts are equal (ultimately that means the lines are identical, so every point is an intersection point).

if they have the same slope but different y- or x-intercepts, it means they are parallel and will never intersect.

The solution to given equation (3/4)x + 3 - 2x = -(1/4) + (1/2)x + 5

is x = -1

Consider given equation.

(3/4)x + 3 - 2x = -(1/4) + (1/2)x + 5

We need to solve this equation.

First we combine the like terms on each side of the equation.

(3/4 - 2)x + 3 = (-1/4 + 5) + (1/2)x

Simplify each side of the above equation.

(-5/4)x + 3 = 19/4 + (1/2)x

Now subtract (1/2)x from each side,

(-5/4)x + 3 - (1/2)x = 19/4 + (1/2)x - (1/2)x

Simplify each side

(-5/4 - 1/2)x + 3 = 19/4 + 0

(-7/4)x + 3 = 19/4

Add -3 to each side of the equation.

(-7/4)x + 3 - 3= 19/4 - 3

(-7/4)x = 7/4

Multiply each side of equation by (-4/7)

(-7/4)x × (-4/7) = 7/4 × (-4/7)

If the right hand side of the equation is non-negative real number, the equation will have two solution that include all real numbers.

An absolute value equation of the form |x| = k (where k is a constant) will have two solutions, one positive and one negative, that are the same distance from 0 on the number line.

To determine if the solutions of the equation include all real numbers, you can examine the value of k. If k is a non-negative real number, then the two solutions of the equation will include all real numbers, because any real number is either positive or negative and the same distance from 0 as k.

For example, if the equation is |x| = 5, the two solutions of the equation are x = 5 and x = -5, which include all real numbers.

On the other hand, if k is a negative real number or a complex number, the equation is not valid and there are no solutions.
