In a particular college class, 60% of the students are female. Of the female students, 75% have long hair. One student is picked randomly in the class. What is the probability that it is a female with long.
If one student is picked randomly in the class, the probability of a student being long haired female is 9 out over 20 students.
What is probability?Probability is defined as the ratio of outcomes that are more likely to occur than all other outcomes of an event. For an experiment with 'n' number of outcomes, the number of favorable outcomes can be denoted by the symbol x. To calculate the likelihood of an event, use the following equation.
Probability (event) = favourable outcomes/ total outcomes (x/n)
Let the number of students in a particular college be 100
Then, if 60% are female that means 60 students are girls (60/100 × 100)
Now, it is said that 75% of females have long hair, that means
75% of 60 girls have long hairs, if we calculate then we find that
⇒ 75/100 × 60
⇒ 3/4 × 60
⇒ 3 × 15
⇒ 45 girls are long haired
Now the probability of a female being longed hair is
⇒ favourable outcomes/ total outcomes
⇒ 45/100
⇒ 9/20
Thus, the probability of a student being long haired female is 9 out over 20 students.

The quadratic equation is [tex]-3/5x^2-2/3x-\frac{1+2\sqrt{2}}{3}[/tex]
Quadratic Equation:
A quadratic function is a function of degree two.
The general form of the quadratic equation is
x² + (sum of roots)x + Product of roots.
Given,
Here we have the roots,
[tex]\frac{-1-\sqrt{2} }{3} ,\frac{-1+\sqrt{2} }{3}[/tex]
And the coefficient with x² is equal to -3/5.
Through the given details we have to find the quadratic equation.
To find the equation we have to identify the sum of roots and the product of roots.
So, the sum of roots is,
[tex]= > \frac{-1-\sqrt{2} }{3} +\frac{-1+\sqrt{2} }{3}[/tex]
[tex]= > \frac{-1 }{3} +\frac{-1 }{3}\\= > \frac{-2}{3}[/tex]

The function's y-intercept is $60.
The equation y = 1/10x+60 can be used to express the function.
y| y 60 is the range.
The equation for the annual cost in dollars, y, based on x, the quantity of game tokens purchased for an arcade member, is represented by the following statements:
A) The function's y-intercept is $60.
B) The equation y = (1/10)x + 60 can be used to express the function.
C) y ≥ 60 is the range.
Typically, the slope-intercept form of the equation of a line is expressed as;

Lily is behind on her homework. The ritualistic teacher assigned exactly 5 homework assignments every day for the past 9 learning days. Here is the amount of homework assignments Lily has been able to get done each night (if she didn’t finish some of the 5 assignments from the night before, she would start work on them the next day): 3, 6, 2, 4, 3, 7, 1, 3, 2. If Lily doesn’t finish all her assignments, she won’t be able to go on a fun field trip next month. Lily can’t do more than 10 assignments in one night. There is one more homework night, with 5 more assignments. Can Lily still make it to the field trip?
Answer:
she cannot go on the field trip.
Step-by-step explanation:
Day 1 = 5, done = 3, remaining = 2.
Day 2 = 2 + 5, done = 6, remaining = 1
Day 3 = 1 + 5, done = 2, remaining = 4
Day 4 = 4 + 5, done = 4, remaining = 5
Day 5 = 5 + 5, done = 3, remaining = 2 + 5
Day 6 = 2 + 5 + 5, done = 7, remaining = 5
Day 7 = 5 + 5, done = 1, remaining = 4 + 5
Day 8 = 4 + 5 + 5, done = 3, remaining = 1 + 5 + 5
Day 9 = 1+ 5+ 5+ 5, done = 2, remaining = 4+5+5
Day 10 = 4+5+5+5, done = 10(maximum assignment done assumed), remaining = 4 + 5
At the end of day 10, she had 9 remaining assignments, so she cannot go on the field trip.

Assume that births are randomly selected and of the 50 births, 49 are girls. use subjective judgment to describe the number of girls as significantly high, significantly low, or neither significantly low nor significantly high.
Based on the information provided, the number of girls in the births cannot be categorized as significantly high, significantly low, or neither significantly low nor significantly high, solely through subjective judgment.
The description of "significantly high" or "significantly low" typically requires statistical analysis and comparison to a reference point or expected value. Without knowing the total number of births or having a reference point for the expected proportion of girls in the births, it is not possible to determine whether the number of girls is significantly high or low.
The term "significantly" in statistics usually involves assessing whether an observed value deviates from an expected value by a statistically significant margin.
Subjective judgment alone cannot accurately assess whether the number of girls in the births is significantly high or low. To determine significance, a statistical analysis would involve calculations such as calculating the expected proportion of girls, performing hypothesis testing, and assessing the p-value to make an informed judgment.
Without these quantitative measures, it is not possible to make an accurate subjective determination of the significance of the number of girls in the births.

What is a gigabyte?A gigabyte is a specific unit of data that's equal to about 1 billion bytes of data. The term gigabyte is typically used to describe the amount of stored data or the capacity of a storage device. For example, an HDD might offer 500 GB of raw capacity but is currently storing only 200 GB of data.
Given that,
A tablet data provider offers different plans for data usage
The plan Raul chose has a monthly fee of $29.99 per month for 5 GB of data with an additional cost of $10 for each gigabyte over 5.
Assume that he will use n gigabyte per month
The monthly fee is $29.99 for 5 GB
∵ The cost per GB after the first 5 GB is $10
∵ The number of GB whose cost is $10 is (n - 5)
∴ His monthly fees = 29.99 + 10 (n - 5) ⇒ current plan
The fees of the unlimited is $59.99 per month
∵ We need the unlimited cheaper than current plane
Let the current plan greater than the unlimited plan
∴ 29.99 + 10 (n - 5) > 59.99
Subtract both sides by 29.99
∴ 10 (n - 5) > 30
Divide both sides by 30
∴ n - 5 > 3
Add both sides by 5
∴ n > 8
Hence, The minimum number is 9 GB to make the unlimited cheaper.

Find the square root of 1,331.
Find the cube root of 1,331.
Find the square of 1,331.
====================================================
Reason:
The cube root undoes the cubing operation.
It's similar to how the square root undoes squaring.
Your calculator should have a cube root button, or an nth root button. If not, then you can type in 1331^(1/3)
The exponent of 1/3 is the same as a cube root.
The result of 1331^(1/3) is 11
11^3 = 11*11*11 = 1331
Interpretation: You have a box that is 11 cm by 11 cm by 11 cm. The volume is 11^3 = 1331 cubic cm.
As you can see, the cube root is useful if you know the volume and want to work backwards to determine the side length of the cube.
the cube root of 1331 = ∛(11 × 11 × 11) = 11.
The square root of 1331 is 36.48287.
Solve the system of equations by substitutión.
y =-4x+5
y = 3x - 16
Answer:
y = - 4x + 5 ---1
y = 3x - 16 ---2
Substitute 1 into 2:
- 4x + 5 = 3x - 16
7x = 21
x = 3
Substitute x into 1:
y = - 4(3) + 5
= - 7
