Without finding the quotient, is the value of the expression (-3 1/3 + 3 1/2) ÷ (-1/4) positive or negative? Explain.
PLZ HELP ASAP
Answers
The expression (-3 1/3 + 3 1/2) ÷ (-1/4) is a division of a positive numerator by a negative denominator, and thus the quotient is negative.
What is an expression?
In mathematics, an expression is a combination of numbers, symbols, and operators (such as +, -, x, ÷) that represents a quantity or a mathematical relationship between quantities.
To determine whether the value of the expression (-3 1/3 + 3 1/2) ÷ (-1/4) is positive or negative, we need to analyze the signs of the numerator and denominator.
First, let's convert the mixed numbers to improper fractions:
-3 1/3 = -10/3
3 1/2 = 7/2
So the expression becomes:
(-10/3 + 7/2) ÷ (-1/4)
Now let's analyze the signs:
The numerator is the sum of two fractions with different signs, so we need to subtract their absolute values and use the sign of the larger one.
|10/3| = 10/3 and |7/2| = 7/2, so the larger fraction is 10/3.
-10/3 + 7/2 = (-20 + 21) / 6 = 1/6, so the numerator is positive.
The denominator is negative because it is a fraction with a negative denominator.
Therefore, the expression (-3 1/3 + 3 1/2) ÷ (-1/4) is a division of a positive numerator by a negative denominator, and thus the quotient is negative.

A random sample of students were asked whether they prefer milk juice or water is it results are summarized in the table.
Answers
Answer:
C
Step-by-step explanation:
The probability of students response is milk is 0.311.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
The table shows the students preference of milk, juice or water.
Total number of students preferred milk = 14
Total number of students = 45
Thus the probability that the students response is milk is
[tex]P(e)=\frac{14}{45}[/tex]
⇒ [tex]P(e)= 0.311[/tex]
Hence we can conclude that the probability of students response is milk is 0.311.

Hello There!
First things first, we should find the rate of change / slope
given two points we can find the slope by using the slope formula which is
(let m be slope)
[tex]m = \frac{y_2-y_2}{x_2-x_2}[/tex]
To find the slope all we have to do is plug in the points
(1,5),(2,10)
remember the first numbers in an ordered pair are the x values and the second numbers are the y values
we also plug in the points of the second ordered pair first so
[tex]m=\frac{10-5}{2-1} \\10-5=5\\2-1=1\\m=\frac{5}{1} or5[/tex]
Knowing the slope we can create an equation to find the x value (a)
y=5x
given the y value we plug in y and solve for x
15=5x
divide each side by 5
15/5=3
5x/5=x
we're left with
x=3
so we can conclude when y =15 x = 3 therefore 3 is your answer
