Answer: x > -3

Steps:

5x > -15                       Bring 5 to the other side (multiplication ---> division)

x > -15/5                      Divide

x > -3

The solution of the inequality 5x > -15 after solving the inequality expression is x > -3.

Given an inequality expression:

5x > -15

It is required to find the value of x after solving the expression.

In order to solve this, it is required to isolate the value of the variable, in this case, x, on one side and the constant terms on the other side.

In order to isolate the variable:

Divide both sides by 5.

What is Nullspace of a matrix?

Nullspace of a matrix A is the solution of the equation AX= 0 where 0 is the zero matrix

Answer:

-4

Step-by-step explanation:

Answer:

-4

Step-by-step explanation:

g(x) tells us what the variable is and what variable should be replaced with a value.

g(1) tells us the value that will replace x.

Plug in 1 to the equation:

-5(1) + 1 = g(1)    (multiply)

-5 + 1 = g(1)       (combine like terms)

-4 = g(1)

Therefore, g(1) is equal to -4

The solution to this question is  27 units the perimeter of kite OBDE.

The perimeter of a shape is the entire length of the shape's boundary as used in geometry. A form's perimeter can be calculated by adding the lengths of all of its sides and edges. In order to calculate it, linear distances such as centimeters, meters, inches, or feet are used.

Here

This is because 15x15 =225

8x8 = 64

225+64=289 and

the square root of 289 is 17 and that is the diameter of the circle and the hypotenuse of the triangle and since the kite has two congruent sides which are both radii or  can be written as half of a diameter times two would be the same as the length of the diameter which is17+the two bottom sides (which are both 5 and 5 )

So 5+ 5 = 10 and

10 + 17 =27 or the perimeter of the kite.

Therefore ,the perimeter of kite OBDE is 27 units.

The total number of schools such that 35% of it is 105 will be 300.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

Suppose the total number of students is x.

35% of x = 105

(35/100)x = 105

x = 105(100/35)

What is Standard Deviation?

A standard deviation (or σ) is a measure of how widely distributed the data is in reference to the mean. A low standard deviation suggests that data is grouped around the mean, whereas a large standard deviation shows that data is more spread out.

Solution:

Mean = 100

Standard Deviation = 13

To solve the given problem we need to calculate the Z - Score

Z = X - Mean / Standard Deviation

The histogram's best summary is option (D), "there are a total of 12 snacks with the same amount of sugar."

While bar charts show categorical variables, histograms show quantitative or numerical data.

The majority of the time, a histogram's numerical data will be continuous (having infinite values).

It would be ridiculous to try and show all possible values of a continuous variable along an axis.

So, the y-axis displays the number of snacks.

The x-axis displays how much sugar is in each snack.

The histogram's first column reveals that 2 snacks each contain between 220 and 224 mg of sugar.

The second column reveals that around 3 snacks have 224–228 mg of sugar.

The third column reveals that 8 snacks range in sugar content from 228 to 232 mg.

Twelve snacks are identified in the fourth column as having between 232 and 236 mg of sugar.

Twelve snacks are identified in the fourth column as having between 232 and 236 mg of sugar.

The fifth column reveals that 11 snacks range in sugar content from 236 to 240 mg.

Three snacks are shown to contain between 240 and 244 mg of sugar in the sixth column.

According to the seventh column, 2 snacks contain 244–248 mg of sugar.

The total number of observations is 41 nibbles, or 2+3+8+12+11+3+2.

So, the best statement that describes the histogram is "The most snacks with the same quantity of sugar are 12 in total."

Samples with natural or matched couplings are known as paired samples (sometimes referred to as dependent samples). This results in the creation of a data set where each data point from one sample is uniquely linked with a data point from the other sample. In statistics, paired data, also known as ordered pairs, refers to two variables in a population's individuals that are linked together to ascertain their association. We refer to two datasets that are identical in length and in which each observation can be "paired" with an observation from the other dataset as having "paired data."

The probability of the product of the given expressions is in the form of x² - (by)² is equal to 1/6.

As given in the question,

Given four expressions are:

( x + y ) , ( x + 5y ) , ( x - y ) and ( 5x - y )

Product of any two expression to have two degree expressions :

( x + y )( x + 5y ) = x² + 6xy + 5y²

( x + y )( x - y ) = x ² - y²

( x + y )( 5x - y ) = 5x² + 4xy -y²

( x + 5y )( x - y ) = x² + 4xy -5y²

( x + 5y )( 5x - y ) = 5x² + 24xy -5y²

(x - y) ( 5x - y) = 5x² - 6xy + y²

Total number of possible outcome of the product with degree 2 = 6

Favourable outcomes in the form of x² - ( by )² is x² - y² = x² -(1y)²

Here b = 1 is an integer.

Number of favourable outcomes = 1

Lead time is the time that passes from the start to the conclusion.  It helps in measuring the time taken to complete a project. It varies from industry to industry.

It is normally calculated as:

Lead time = processing time + post-processing time.

Given,

lead time = 8 days

Order place date = 14 days

uncertainty period  = order date + lead time
