Answer:

23

Step-by-step explanation:

15% of 20 = 3  then add the 3 to the 20 to get 23

23Answer:

Step-by-step explanation:

15/100*20 = 3

20+3 = 23

The percentage of measurements that are above the 39th percentile is 61%.

To calculate the percentage of measurements above the 39th percentile, we need to find the complement of the percentile value. The 39th percentile represents the value below which 39% of the measurements fall. Therefore, the complement of the 39th percentile is the percentage of measurements above that value. Since the total percentage adds up to 100%, subtracting 39% from 100% gives us the percentage of measurements above the 39th percentile, which is 61%.

In summary, the percentage of measurements that are above the 39th percentile is 61%. This means that 61% of the measurements are higher than the value corresponding to the 39th percentile.

What is the percentage of measurements that fall above the 39th percentile?

Answer: x= -12

Step-by-step explanation:

These are corresponding angles which means they are the same. X+62= 50. Subtract 62 from both sides. X= -12

Answer:

x = -12

Step-by-step explanation:

Note that the 50 degree angle and the angle x + 62 are equal, because both are formed by a single diagonal crossing two parallel lines.

Thus, 50 = x + 62, or x = -12

The water level is rising at the rate of 0.36 ft/min

For given situation, using similar triangles, the height and width of the water is proportional to the height and width of the trough.

w / h = 5 / 1

w = 5h           ...........(1)

The volume of the water is:

V = AL

V = (½ wh) (12)

V = 6wh

V = 6(5h)h                       ............(from (1))

V = 30h²

Now we find the derivative of V with respect to time t:

So, the rate of water being filled in the trough is:

dV/dt = 60 * h * dh/dt

We have been given that dV/dt = 9

and  h = 5 inches

             = 0.4167 ft,

Substitute these values in above equation of dV/dt,

9 = 60 * 0.4167  * dh/dt

9 = 25.002 * dh/dt

dh/dt = 9/25.002

dh/dt ≈ 0.36 ft/min

Therefore, the water level is rising at the rate of 0.36 ft/min

If she sold the gold bracelet at $2012, the profit would be $1212

Let  original price of the gold bracelet be x

Mrs Tan wanted to make a profit of 52%

The selling price would be $1216

Selling price = x + 52% of x

1216 = x + (52/100)x

1216 = 152/100x

x = 1216(100/152)

x = 800

The original price is $800

The price at which she sells the gold bracelet is 2012

Profit = selling price - original price

= 2012 - 800

= 1212

Therefore, if she sold the gold bracelet at $2012, the profit would be $1212

Answer:

q ^ p

Step-by-step explanation:

The symbolic form of the statement would be:

q ∧ p

Where q represents "m angle A + m angle B = 180°" and p represents "angle A and Angle B are supplementary".

The ∧ symbol represents "and" in logic, so the statement can be read as "q and p".

Statement II and III are not true, while statement I is true. Therefore, the correct answer is c. II and III only.

I. 68% of the values are between 37.6 and 50.4: This statement is true. In a normal distribution, approximately 68% of the values fall within one standard deviation of the mean. In this case, the range of 37.6 to 50.4 falls within one standard deviation of the mean (44 ± 3.2).

II. 13.5% of the values are less than 40.8: This statement is not true. In a normal distribution, approximately 50% of the values fall below the mean. Since the mean is 44, it is not possible for only 13.5% of the values to be less than 40.8.

III. 5% of the values are lower than 37.6 or higher than 50.4: This statement is not true. In a normal distribution, approximately 2.5% of the values fall below the mean minus one standard deviation, and approximately 2.5% of the values fall above the mean plus one standard deviation. Since the range of 37.6 to 50.4 falls within one standard deviation of the mean, it is not possible for 5% of the values to be outside this range.

Same age

See explanation below

Let the age of Jasmine = y

Multiplying Jasmine age by 3 and adding 6:

= (y × 3) + 6

= 3y + 6

Multiplyng the sum by 2:

2 × the sum = 2 × (3y + 6)

= 6y + 12

Let James age = z

Multiplying the age by 2 and adding 4:

James age × 2 = z × 2 = 2z

adding 4 = 2z + 4

Multiplying the sum y 3:

3 × the sum = 3 × (2z + 4)

= 6z + 12

Now since they are twins, they ae most likely same age

This means:

6y + 12 = 6z + 12

subtracting 12 from both sides:

6y = 6z

dividing both sides by 6:

y = z

Hence, Jasmine age is the same as James age

B) The expression for Jasmine = 2(3y + 6) = 6y + 12

The expression for James = 3(2z + 4) = 6z + 12

let the twin's age = 2, 3, 4, 5

when twin's age = 2

6y + 12 = 6(2) + 12 = 12 + 12 = 24

6z + 12 = 6(2) + 12 = 12 + 12 = 24

when twin's age = 3

6y + 12 = 6(3) + 12 = 18 + 12 = 30

6z + 12 = 6(3) + 12 = 18 + 12 = 30

when twin's age = 4

6y + 12 = 6(4) + 12 = 24 + 12 = 36

6z + 12 = 6(4) + 12 = 24 + 12 = 36

when twin's age = 5

6y + 12 = 6(5) + 12 = 30 + 12 = 42

6z + 12 = 6(5) + 12 = 30 + 12 = 42

Answer:

\(\sqrt{10}\)

Step-by-step explanation:

The distance between two points can be found using the Pythagorean Theorem \(a^{2} + b^{2} = c^{2}\).

This is because, if you connected your two points with a line, that line could be defined as the hypotenuse of a right triangle. the base of that triange is the distance between the x coordinates (\(x_{2} -x_{1}\)) and the height by the distance between the y coordinates (\(y_{2} - y_{1}\)). Sine these are the sides of the right triangle, they are equal to a and b above (c is the hypotenuse that we are trying to find). So, we calculate the two distances above and get 3 and 1 (for x and y respectively). 3^2 + 1^ 2 =10. So the answer is square root 10.

Answer:

r = 59

Step-by-step explanation:

59 + r = 118

59 + r - 59 = 118 - 59

r = 59

Since 59 is being added to r, and you want r alone, you must subtract 59 from the left side of the equation. The rule is that you must do the same operation to both sides of the equation. Therefore, to solve for r, subtract 59 from both sides of the equation.

The probability of choosing a white marble from the box can be determined by dividing the number of white marbles by the total number of marbles.

In this case, the box contains 7 green marbles and 6 white marbles, so the total number of marbles is 13.

To find the probability, we divide the number of white marbles (6) by the total number of marbles (13):

Probability of choosing a white marble = 6 / 13

To express this as a decimal number, we divide 6 by 13:

Probability of choosing a white marble ≈ 0.4615 (rounded to 4 decimal places)

The probability of choosing a white marble from the box is approximately 0.4615.

A linear system with 3 equations and 4 variables by representing it with an augmented matrix and bringing the matrix to reduced row-echelon form can be solved.

A mathematical representation of a system based on the application of a linear operator is known as a "linear system" in systems theory. Ordinarily, compared to nonlinear systems, linear systems display much simpler features and properties. The automatic control theory, signal processing, and telecommunications all heavily rely on linear systems as a mathematical abstraction or idealisation.

Linear systems, for instance, are frequently used to model the propagation medium for wireless communication systems. An operator, H, that converts an input, x(t), into an output, y(t), a kind of black box description, can be used to describe a general deterministic system.

The superposition principle, or alternatively both the additivity and homogeneity properties, must be satisfied by a system to be considered linear, and only then.

The number of adults at the public pool that day is 284 and the number of children is 147.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

Let x be the number of adults and y be the number of children who used the swimming pool.

Total number of people used the swimming pool = 431

x + y = 431

Daily price for adults = $2.00

Daily price for children = $1.50

Total amount for admission = $788.50

2x + 1.5y = 788.5

We got two linear equations here :

x + y = 431 and 2x + 1.5y = 788.5

x + y = 431 ⇒ x = 431 - y

Substituting this in second equation,

2(431 - y) + 1.5y = 788.5

862 - 2y + 1.5y = 788.5

-0.5y = -73.5

y = 147

x = 431 - 147 = 284

Hence the number of adults is 284 and the number of children is 147.
