Giselle's age is 15 years.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Giselle's age = x

Father age = 3x

Now,
After 10 years his age will be 5 more than twice her age.

This can be written as,

3x + 10 = 5 + 2 (x + 10)

Solve for x.

3x + 10 = 5 + 2x + 20

3x - 2x = 5 + 20 - 10

x = 15

Thus,

Answer:

18

Step-by-step explanation:

x - y = 6

x = 6

2x = 6 · 2 = 12

12 + 6 = 18

x is twice the value of y can be written as:

x= 2y

then we replace x with 2y in the given equation

x - y = 6

2y - y = 6

y = 6

then to find x we replace y with 6 in either of the equations

x = 2y

x = 2(6) = 12

or

x - 6 = 6

x= 6 + 6 = 12

now find value if x + y

12 + 6 = 18

Answer:

The answer to your question is: first piece = 4 in, second piece = 8 in, third piece = 12 in

Step-by-step explanation:

Data

total length = 24 inches

first piece = x in

second piece = 2x

third piece = 3x

Equation

x + 2x + 3x = 24

6x = 24

x = 24/6

x = 4 lengths of the first piece

second piece = 2(4) = 8 inches

third piece = 3(4) = 12 inches

1) The probability table is calculated by the formula. 2) the probability that a student scores higher than 1.5 is 0.9, and 3) the probability a student scores between 2.5-3.5 is 0.47.

1)

We know that the probability of any event

= no. of observation for the event/total n. of observation

Here, the total no. of observations is 250

Hence we get the following probability table

GPA             Frequency

0-0.5               1/250

0.5-1                4/250

1-1.5               20/250

1.5-2              35/250

2-2.5             67/250

2.5-3             58/250

3-3.5             47/250

3.5-4             18/250

2)

The probability that a student's GPA is higher than 1.5 is
P(1.5-2) + P(2-2.5) + P(2.5-3) + P(3-3.5) + P(3.5-4)

= (35 + 67 + 58 + 47 + 18)/250

= 225/250

= 0.9

3)

The probability that a student's GPA is between 2.5 and 3.5

= P(2.5-3) + P(3-3.5)

= (58 + 47)/250

= 105/250

= 0.42

Non-overlapping intervals:

If the intervals(say interval a & interval b) doesn't overlap then the set of pairs form by [a. end, b. start] is the non-overlapping interval.

In mathematics, a (real) interval is a set of real numbers that contains all real numbers lying between any two numbers of the set. For example, the set of numbers x satisfying 0 ≤ x ≤ 1 is an interval which contains 0, 1, and all numbers in between. Other examples of intervals are the set of numbers such that 0 < x < 1, the set of all real numbers {\displaystyle \mathbb {R} }\mathbb {R} , the set of nonnegative real numbers, the set of positive real numbers, the empty set, and any singleton (set of one element).

Let's take the below mentioned overlapping intervals example to explain the idea: If both ranges have at least one common point, then we say that they're overlapping. In other words, we say that two ranges and are overlapping if: On the other hand, non-overlapping ranges don't have any points in common.

Given N set of time intervals, the task is to find the intervals which don’t overlap with the given set of intervals.

Examples:

interval (a) = { {1, 3}, {2, 4}, {3, 5}, {7, 9} }

Output:  [5, 7]

The only interval which doesn’t overlaps with the other intervals is [5, 7].

interval (a) = { {1, 3}, {9, 12}, {2, 4}, {6, 8} }

Output: [4, 6]  and [8, 9]

There are two intervals which don’t overlap with other intervals are [4, 6], [8, 9].

As the probabilities of random variables are negative so we can expect to lose roughly 50 cents on each $1.00 ticket we purchase.

The rules of the "numbers" game are simple: a player selects a three-digit number between 000 and 999. Anyone who picks the winning number receives a payout equal to 600 times their original wager. The winning number is decided by a publicly disclosed source. The majority of bets were for $1 or less, and frequently.

A permutation is an arrangement (or ordering) of a collection of items. (We can also arrange only some of the objects in the set.) The arrangement of the objects in a permutation depends on their order.

The random variable-0.499/1000

The random variable "winning" are $1 and $600.

and their probabilities are 999/1000 and 1/1000, respectively.

The expected "winnings" are calculated as follows:

=(999/1000)(-1)+(1/1000)(500)

=-0.499/1000

=-0.499 cents

The measure of missing angles is 48° and 36°.

The angle sum property of a triangle states that the sum of the three internal angles of a triangle equals 180 degrees. Three line segments combine to form a triangle, a closed shape having interior and exterior angles. When the values of the other two angles are known, one may utilize the angle sum property to determine the measure of an unknown interior angle.

Given Measure of one angle= 96, one angle= 2x, other angle= x + 12.

Using the angle sum property, we get

96 + 2x + x + 12 = 180

108 + 3x = 180

3x = 180 - 108

3x = 72

x = 72/3

x = 24

So, one angle = 2(24

= 48

The dimensions of the rectangle: length = 15 km and width = 11 km

Let l be the length of rectangle and w be the width of the rectangle.

A rectangle has perimeter 52 km

Using the formula of the perimeter of rectangle we get an equation,

2(l + w) = 52              ............(1)

And its area is 165 sq-km.

Using the formula of the area of rectangle we get an equation,

l * w = 165               ............(2)

From equation (1),

l = 26 - w

Subatitute above value of l in equation (2),

(26 - w) * w = 165  

26w - w² = 165

w² - 26w + 165 = 0

(w - 15)(w - 11) = 0

w = 15     or         w = 11

For w = 15,

l = 26 - 15

l = 11

For w = 11,

l = 26 - 11

l = 15

But as we know, the length of rectangle is always greater than the width,

l = 15 and w = 11 is true .

Therefore, the length of rectangle = 15 km and width of rectangle = 11 km

Answer: 9

Step-by-step explanation: The number of sides that a regular polygon has can be determined by the measure of one of its exterior angles. A regular polygon is a polygon with sides of equal length and angles of equal measure.

The measure of one exterior angle of a regular polygon is equal to 360° divided by the number of sides of the polygon. Therefore, if one exterior angle of a regular polygon measures 40°, we can use the following equation to find the number of sides of the polygon:

exterior angle measure = 360° / number of sides

40° = 360° / number of sides

number of sides = 360° / 40°

number of sides = 9

Therefore, a regular polygon with one exterior angle measuring 40° has 9 sides.

Answer: August 12th

Step-by-step explanation: 4 and 6 have common multiples of 2, so you need to multiply 6 by 2 and 4 by 3. Both get you 12, so the earliest they have tennis practice is the 12th of August (12 days after July 31st).

Answer:

August 12

Step-by-step explanation:

To solve this question, we need to find the Least Common Multiple (LCM) of 4 and 6.

Since we know that Nick and Mark both had practice on July 31st, we can simply add {LCM of 4 and 6} days to that date to get when they will next both have practice.

To find the LCM of 4 and 6, find the prime factorization of both:

[tex]4 = 2 \times 2[/tex]          [tex]6 = 2 \times 3[/tex]

Now, take the largest quantity of each distinct prime number and multiply them together:

The largest number of 2's is 2. The largest number of 3's is 1. So, we multiply

[tex](2 \times 2) \times (1 \times 3)[/tex]

[tex]= 4 \times 3[/tex]

[tex]= 12[/tex]

Therefore, the LCM of 4 and 6 is 12.

This means that Nick and Mark will have practice on the same day in 12 days.

The last step to solve this problem is to add 12 days to July 31.

[tex]\textrm{July } 31 + 12 \textrm{ days} = \textrm{August } 12[/tex]

Nick and Mark will next have practice on the same day on August 12.

Step-by-step explanation:

The rate of the water rising in the tank when the depth of the water is 1 ft is 56.05 ft/min.

The rate of change of volume is-

dV/dt = 11 ft3/min.

Volume of cylindrical cone = (1/3)πr²h

As we're trying to find dh/dt, we need to calculate the volume within terms of just one variable, h.

Diameter =  22 ft

Thus, radius is 11 ft

By using height and radius of a water in the tank, we may calculate h using similar ratios.

11/44 = r/h

1/4 = r/h

r= h/4

Put into volume;

V = (1/3)π(h/4)h²

V = (1/3)(π)h³ / (16)

dV/dt = [(1/3)(3)(π)(h)² / 16](dh/dt)

V = [(π)(h)² / 16](dh/dt)

Solve for (dh/dt) ;

dh/dt = (dV/dt)(16) / [((π)(h)²]

Now, the change in volume is dV/dt = 11 ft³/min

dh/dt = (11 ft³/min)(16) / [((π)(h)²]

For h = 1 ft,

dh/dt = (11 ft³/min)(16) / [((π)(1 ft)²]

dh/dt ≈ 56.05 ft/min

Thus, the rate of the water rising in the tank when the depth of the water is 1 ft is 56.05 ft/min.
