The numerical value of a dependent variable is dependent on the value of the independent variable. In other words, the numerical value of the dependent variable changes based on the value of the independent variable. For example, in the equation y = 2x + 3, the numerical value of y (the dependent variable) is dependent on the value of x (the independent variable). If x is 1, then the numerical value of y is 5 (2*1 + 3). If x is 2, then the numerical value of y is 7 (2*2 + 3). So, the numerical value of the dependent variable is dependent on the value of the independent variable.

The expression that represents a 20% discount off the price of an item that originally cost d dollars include:

0.8d

d - 0.2d

Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.

In this case, the cost of the item is d. Since there's a 20% discount, the new cost will be:

= d - (20% × d)

= d - 0.2d

= 0.8d

The cost is 0.8d.

Answer:

23/3

Step-by-step explanation:

Convert the mixed number 723 7 2 3 into an improper fraction first by multiplying the denominator (3) by the whole number part (7) and add the numerator (2) to get the new numerator. Place the new numerator (23) over the old denominator (3) .

72/3 as an improper fraction is 23/3.

To convert the mixed number72/3 to an indecorous bit, we follow these way

Multiply the whole number( 7) by the denominator of the bit

= 7 x 3

= 21.

Add the result to the numerator of the bit

= 21 + 2

= 23.

Write the sum as the numerator of the indecorous bit 23.

The denominator remains the same 3.

Thus, 72/3 as an indecorous bit is 23/3.

Answer:

2/7.

Step-by-step explanation:

Using order of operations (PEMDAS):

0.9 (3 / 2.25 - 1/8( 1 2/3 + 1/9)) - 4/7 / 0.8

= 0.9 (3 / 2.25 - 1/8( 5/3 + 1/9)) - 4/7 / 0.8

= 0.9 (3 / 2.25 - 1/8( 16/9) - 4/7 / 0.8

= 0.9 (3 / 2.25 - 2/9) - 4/7 / 0.8

=  0.9 (12/9 -  2/9) - 4/7 / 0.8

=  0.9 * 10/9 - 5/7

Step-by-step explanation:

the pitcher is in the middle of the diamond square thingy,the length is 30, so half of 30 is 15

After evaluating the given logical expression, we find that the value of the Boolean variable "b" is false.

The value of the Boolean variable "b" can be found by evaluating the given logical expression.

Given:

int x = 3;

int y = 4;

int z = 2;

boolean b = !((x > y) || ((y + z) >= (x - z)))

Let's break down the expression step by step:

1. Evaluate the sub-expression (x > y):

  Since x is 3 and y is 4, the expression (x > y) evaluates to false.

2. Evaluate the sub-expression ((y + z) >= (x - z)):

  We have y = 4, z = 2, and x = 3.

  Substituting the values, the expression ((y + z) >= (x - z)) becomes (4 + 2) >= (3 - 2), which simplifies to 6 >= 1.

  Thus, this sub-expression evaluates to true.

3. Negate the result of the entire expression:

  Since the expression ((x > y) || ((y + z) >= (x - z))) evaluates to false || true, which is true.

  Negating true gives us false.

Therefore, the value of the Boolean variable "b" is false.

In conclusion, after evaluating the given logical expression, we find that the value of the Boolean variable "b" is false.

2.375 number of standard deviation from mean outing with 74 assists.

Data dispersion in regard to the mean is quantified by a standard deviation, or "σ"

By figuring out how far off from the mean each data point is, the standard deviation may be determined as the square root of variance.

The deviation within the data set is bigger when the data points are more away from the mean.

According to the question,

Mean of the number of assists per match is 55

Standard deviation of the same is 8

Let x be the number of standard deviation from mean outing with 74 assists

=> 55 + 8x = 74

Solving for x

=> 8x = 74 - 55

=> 8x = 19

=> x = 19 / 8

=> x = 2.375

Hence, 2.375 number of standard deviation from mean outing with 74 assists.

Using the conversion to find, the tank holds 379 liters.

In the given question,

There are about 3.79 liters in 1 gallon. Kendra’s fish tank contains 100 gallons of salt water.

We have to find how many liters the tank holds.

Firstly we learn about gallon

The gallon is a unit of volume.

We measure liquid things in gallon.

As given that

1 gallon = 3.79 liters

We have to find the 100 gallons in liters.

To find the 100 gallons in liters we multiply 100 by 3.79 because 1 gallons equal to 3.79 liters.

So 1 gallon = 3.79 liters

100 gallon = 100 × 3.79 liters

100 gallon = 379 liters

Hence, the tank holds 379 liters.

Answer:

Step-by-step explanation:

x * (x - 2) =  28

x^2 - 2x = 28

Solving by completing the square:

(x - 1)^2 - 1 = 28

(x - 1)^2 = 29

x = +/-√29 + 1

x = 6.38516, -4.38516

x must be positive so it = 6.38516.

The shortest side = x - 2 = 4.385.

Answer:

It's not -4.44, and if it was -3.14 it would be closer to the -3 tick on the line. With the negative square root of 17 being 4.12 it's not that either. -11/3 is 3.6666667 or something along those lines so it would be closer to the -4 tick on the line, so I'm pretty sure you got it.

The 95% confidence interval for the population mean is (16.426, 26.574

To find the 95% confidence interval, we can use the formula:

Confidence interval = sample mean ± (z-score)*(population standard deviation/√n)

where the z-score for a 95% confidence level is 1.96.

Plugging in the values given in the question, we get:

Confidence interval = 21.5 ± (1.96)*(19.4/√49)

Simplifying this expression, we get:

Confidence interval = 21.5 ± 5.074

Therefore, the 95% confidence interval for the population mean is (16.426, 26.574) as an open-interval.
