Using a system of equations, it is found that they expect to sell 175 adult tickets and 350 student tickets.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable a: Number of adults that attend.
  • Variable s: Number of students that attend.

They expect that twice as many students as adults will attend, hence:

s = 2a.

Their goal is to earn $1,500 from ticket sales, hence:

10a + 5s = 1500.

10a + 5(2a) = 1500.

20a = 1500.

a = 1500/20.

a = 175.

s = 2a = 2 x 175 = 350.

They expect to sell 175 adult tickets and 350 student tickets.

Male and female high school students reported how many hours they worked each week in summer jobs. The data is represented in th
fgiga [73]

The values of data that might affect the statistical measures of spread and center is that: D. The males have a suspected significant high outlier.

<h3>What is a box and whisker plot?</h3>

A boxplot is also referred to as box and whisker plot and it can be defined as a type of chart that can be used to graphically represent the five-number summary of a data set with respect to locality, skewness, and spread.

In Mathematics, the five-number summary of any box and whisker plot include the following:

  • Minimum
  • First quartile
  • Median
  • Third quartile
  • Maximum

By critically observing the box and whisker plots which represent the number of hours the students worked in summer jobs, we can reasonably infer and logically deduce that male students have a significant high outlier because the maximum value (37) is very far from the third quartile (15).

Consider the roots of a cubic equation with integral coefficients: −1, −4, and 3. Which choice is a factor of the cubic equation
mash [69]

Answer:

D

Step-by-step explanation:

Lets go case by case.

Given the roots, a factor will be part of the equation if for some of the roots the factor becomes null, i.e., equal to 0.

Is there any root that makes (x+3)=0? No, as it only becomes 0 for x = - 3 and -3 is not a root. So A NO!

Is there a root that makes (x-1)=0? No, as it only becomes 0 for x=1 and 1 is not a root. So B NO!

(x-4)=0 only for x=4, and as 4 is not a root, C NO!

The last, (x-3)=0 if x=3. As 3 is one of the roots, (x-3) is a factor of our equation!

D is the only correct option!

Which are rational and irrational? Thanks in advance :)
DochEvi [55]

Answer:

3\frac{1}{2}-rational

\pi -irrational

-\frac{2}{3}-rational

\sqrt{16} -rational

\sqrt{3} -irrational

18-rational

0.625-rational

0.987987987...-rational

Step-by-step explanation:

Rational numbers:

-are all numbers you can write as a quotient of integers  \frac{a}{b} , b\neq 0

-include terminating decimals. For example, \frac{1}{8}=0.125

-include repeating decimals. For example, \frac{1}{3} =0.33333....

Irrational numbers:

-have decimal representations that neither terminate nor repeat. For example, \sqrt{2}=1.414213....

-cannot be written as quotients of integers
