Answer:

the number of recruits neither be college graduate and nor army veterans is 30

Step-by-step explanation:

The computation of the number of recruits neither be college graduate and nor army veterans is as follows;

= Total recruits - (college students + army veterans - both college graduates & army veterans)

= 120 recruits - (80 + 25 - 15)

= 120 recruits - 90  

= 30

hence, the number of recruits neither be college graduate and nor army veterans is 30

Combination tells the number of ways an object can be arranged. The number of all of the possible combinations Gabby can have is 9.

The combination helps us to know the number of ways an object can be arranged without a particular manner. A combination is denoted by 'C'.

\(^nC_r = \dfrac{n!}{r!(n-r)!}\)

where,

n is the number of choices available,

r is the choices to be made.

We know that the number of options of the flower with Gabby is 3( daisies, carnations, or sunflowers) and the color choices she has is (clear, red, or blue), therefore, she \(^3C_1\) choices for the flower, also, she has \(^3C_1\) choices for color.

\(\text{Total number of choices with Gabby} = \text{Choices of flower} \times \text{Choices of color}\)

                                                         \(= ^3C_1 \times ^3C_1 \\\\= 9\)

On solving the provided question, we can say that - the probability the coin comes up heads and the card is a heart is 1/26

The probability that something will occur is the foundation for it. The foundation of theoretical probability is the justification of probability. For instance, the theoretical likelihood of receiving heads while tossing a coin is 1/2. A branch of mathematics known as probability measures the possibility of an event happening or a proposition being true. The probability of an occurrence is a number between 0 and 1, where roughly 0 denotes the event's improbability and 1 denotes certainty.

let

e1 be the drawing a card from a deck of 52 cards,

and,

e2 be the flipping of a coin,

These two events are mutually exclusive. so,

\(P(E1) = 4/52 = 1/13\\P(E2) = 1/2\\now, P(E1 and E2 ) = P(E1) * P(E2) = (1/13)*(1/2) = 1/26.\\\)

Final Price = 1014

Initial Price = 975

SALES TAX FORMULA: (Final/Initial Price - 1) * 100 = ANSWER

(1014/975 - 1)* 100 = 4%

Answer:C

Step-by-step explanation:

288 divided by 4 equals 72

Option C is correct, y=72x is the equation which represents the number of times her heart beats per minutes.

A division is a process of splitting a specific amount into equal parts.

The equation that represents the relationship between the number of times Lupe's heart beats per minute and the time (in minutes) is:

y = 72x

where y is the number of times Lupe's heart beats per minute, and x is the time in minutes.

We can see this by dividing the total number of heart beats by the time in minutes:

y = (288 beats / 4 minutes) = 72 beats/minute

Hence, y=72x is the equation which represents the number of times her heart beats per minutes.

The distance between the point (-1, 1, 1) and the set 5 = {(x, y, z): 2 = xy} Z is √3. to find the distance, we need to determine the closest point on the set to (-1, 1, 1).

Since the set is defined as 2 = xy, we can substitute x = -1 and y = 1 into the equation to obtain 2 = -1*1, which is not satisfied. Therefore, the point (-1, 1, 1) does not lie on the set. As a result, the distance is the shortest distance between a point and a set, which in this case is √3.

To explain the calculation in more detail, we first need to understand what the set 5 = {(x, y, z): 2 = xy} represents. This set consists of all points (x, y, z) that satisfy the equation 2 = xy.

To find the distance between the point (-1, 1, 1) and this set, we want to determine the closest point on the set to (-1, 1, 1).

Substituting x = -1 and y = 1 into the equation 2 = xy, we get 2 = -1*1, which simplifies to 2 = -1. However, this equation is not satisfied, indicating that the point (-1, 1, 1) does not lie on the set.

When a point does not lie on a set, the distance is calculated as the shortest distance between the point and the set. In this case, the shortest distance is the Euclidean distance between (-1, 1, 1) and any point on the set 5 = {(x, y, z): 2 = xy}.

Using the Euclidean distance formula, the distance between two points (x₁, y₁, z₁) and (x₂, y₂, z₂) is given by:

\(distance = √((x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²).\)

In our case, let's choose a point on the set, say (x, y, z) = (0, 2, 1). Plugging in the values, we have:

\(distance = √((0 - (-1))² + (2 - 1)² + (1 - 1)²) = √(1 + 1 + 0) = √2.\)

Therefore, the distance between the point (-1, 1, 1) and the set 5 = {(x, y, z): 2 = xy} is √2.

ANOVA (Analysis of Variance) is a statistical test used to analyze differences between group means.

The test involves partitioning the total variation into two components:

variation between groups (SSB, sum of squares between) and variation within groups (SSW, sum of squares within).

The total sum of squares (SST) represents the overall variability in the dataset.

The computational shortcut for ANOVA states that the sum of squares within groups (SSW) can be calculated by

subtracting the sum of squares between groups (SSB) from the total sum of squares (SST).

Step-by-step explanation:

a = \(\pi\)\(r^{2}\) for a circle.  We do not want to find the area for a whole circle.  We only want to find the area for part of a circle.  a hole circle is 360 degrees.

a = \(\frac{88}{360}\)\(\pi\)\(r^{2}\)

a = \(\frac{88}{360}\)\(\pi\)(\(5^{2}\))

a = 19.2 rounded.

The area of the sector of circle is b. 19.20 square meter.

The space enclosed by the sector of circle is called area of the sector of circle.Mathematically,

Area of the sector of circle, A = θ/360πr²

where θ is the angle of the arc and r is the radius of the circle.

Now it is given that,

radius of the circle, r = 5m

Angle of arc, θ = 88°

Therefore, area ofsector of circle A = θ/360πr²

Put the values,

A = 88/360 π 5²

Solving the equation we get

A = 19.20 square meter.

Hence,the area of the sector of circle is b. 19.20 square meter.
