dr. aguilera conducts psychological research that examines factors associated with college student academic performance. she administered a survey to 127 participants from her university’s student subject pool. in the survey, she asked students to report their current college grade point average (gpa). dr. aguilera also asked questions about sleeping, eating habits, and social media use.

Answers

Answer 1

According to Dr. Aguilera's findings, excessive levels of anxiety are associated with poor academic performance. Sleep duration, on the other hand, is unrelated to excellent or poor academic performance.

we are able to reach this end due to the fact:Dr. Aguilera determined a main significance in the relationship among anxiety and academic success.moreover, this quantity is terrible, indicating a poor dating between these  variables.consistent with this bad connection, the greater the value of one variable, the lower the fee of the opposite. As a result, the extra anxiety, the decrease the educational achievement.The phrase "correlation" refers back to the hyperlink between two variables. As a end result, if the adjustment is equal to zero, there may be no link between the two variables.The association among sleep hours and educational fulfillment became nil. this means that those elements have no effect on each other and are unrelated.it is important to word that the operational definition of this test is big since it presentations the measurements utilised to acquire the findings in addition to the general control of the test.nevertheless, the cohort impact is important for averting hurdles to size and research methodologies.

Answers

12% of  students are enrolled in less than three courses and taking a math course

For given question,

50% of students are enrolled in less than three courses and 33% of students are taking a math class.

The probability that the students are enrolled in less than three courses is 0.5

P(A) = 0.5

The probability that the students are taking a math class is 0.33

P(B) = 0.33

if 71% of students are either enrolled in less than three courses or taking a math course.

P(A ∪ B) = 0.71

We need to find the percentage of students that are enrolled in less than three courses and taking a math course.

i.e., we need to find P(A ∩ B)

We know that, P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

P(A ∩ B) = 0.5 + 0.33 - 0.71

P(A ∩ B) = 0.12

So, 12% of  students are enrolled in less than three courses and taking a math course.

Therefore, 12% of students are enrolled in less than three courses and taking a math course.

Answers

The integers are 14 and 16.

How to calculate the value?

Let the integers be represented by x and x+2.

It was stated that the consecutive even integers such that 6 times the smaller integer is 36 more than 3 times the larger integer.

This will be:

6(x) = 3(x + 2) + 36

6x = 3x + 6 + 36

6x = 3x + 42

6x - 3x = 32

3x = 42

Divide

3x/3 = 42/3

x = 14.

The larger number will be:

= 14 + 2

how do you find the y-intercept from vertex form

Answers

It is found that the intercepts can be found from vertex form, if the graph is hovering above the x axis (k<0).

What is y-intercept of a function?

The intersection of the graph of the function with the y-axis gives y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Assume that we've got: y = f(x) At y-axis, we've got x = 0, so putting it will give us the y-intercept. Thus, y-intercept of y = f(x) is y = f(0)

If a quadratic equation is written in the form y=a(x-h)² + k

therefore it is called to be in vertex form. It is called so because when you plot this equation's graph, we will see vertex point(peak point) is on (h,k)

To convert the given equation to vertex form, We will take out coefficient of x squared, and then inside the bracket, we try to make perfect square like situation.

To find the intercepts, if the graph is hovering above the x axis (k<0) then there will be no real solutions for the x intercept.

share. Express her capital gain
She sold them in 2007 for $55.10 per
as a percent, rounded to the nearest tenth of a percent.

Answers

Maria's capital gain is 55.2%.

Here, we are given that Maria purchased 1,000 shares of stock for $35.50 per share in 2003.

Thus, the total cost price of these shares = 1000 × 35.5

= $35500

In 2007, she sold all of the stocks for $55.10 per share

Thus, the total selling price of these shares = 1000 × 55.1

= $55100

Now, absolute gain = selling price - cost price

Here, Maria's absolute gain will be-

= 55100 - 35500

= 19600

Now, her percentage gain will be given by-

Gain % = absolute gain/ initial value × 100

= 19600/35500 × 100

= 55.2

Thus, Maria's capital gain is 55.2%.

Find the equation of the line which passes through (6,2) and is parallel to the line with equation 3y=5x+2

Answers

Answer:

3y = 5x - 24

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

3y = 5x + 2 ( divide through by 3 )

y = [tex]\frac{5}{3}[/tex] x + [tex]\frac{2}{3}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{5}{3}[/tex]

• Parallel lines have equal slopes , then

y = [tex]\frac{5}{3}[/tex] x + c ← is the partial equation of the parallel line

to find c substitute (6, 2 ) into the partial equation

2 = 10 + c ⇒ c = 2 - 10 = - 8

y = [tex]\frac{5}{3}[/tex] x - 8 ← equation in slope- intercept form

multiply through by 3 to clear the fraction

3y = 5x - 24 ← equation of parallel line

which row of pascal’s triangle would you use to expand (2x 10y)15? row 10 row 12 row 15 row 25 how many terms are in this expansion? 3 terms

Answers

15th row of the Pascal's Triangle is used to expand [tex](2x+10y)^{15}[/tex]. There will be 16 terms in the expansion.

Pascal's Triangle is used to find the co-efficient for binomial expansions.

The nth row of the Pascal's Triangle gives the coefficients in the expansion of binomial expressions of degree n. For example, in the expansion of [tex](x+y)^2[/tex] , the binomial coefficients are 1,2,1 which is given in the 2nd row of Pascal's Triangle. Also the expansion has three terms, therefore. The Pascal triangle starts with 0th row consisting of only 1.

Here the given expression is [tex](2x+10y)^{15}[/tex] of degree 15. So its binomial coefficient is given in the 15th row of Pascal's triangle.

The number of terms in the binomial expansion of degree n will be n+1 because the coefficients in nth row will n+1 in number.

Hence there will be 16 terms in the expansion of [tex](2x+10y)^{15}[/tex].

if the length of a rectangle is increased by 30 percentage and the width of the same rectangle is decreased by 30 what is the affect on the area

Answers

Answer:

The area will decrease by 9%.

Step-by-step explanation:

The area of a rectange is given by the formula below.

[tex]\boxed{\text{Area of rectangle}= \text{length}×\text{width}}[/tex]

Let the original length and width of the rectangle be L and W respectively.

Start by finding the original area:

Original dimensions

Length= L= 100%L

Width= W= 100%W

Original area= LW

Let's find the dimensions of the new rectangle in terms of L and W.

New dimensions

Length= (100% +30%)L= 130%L

Width= (100%-30%)W= 70%W

New area

[tex] = \frac{130}{100} L \times \frac{70}{100} W[/tex]

[tex] = \frac{91}{100} LW[/tex]

= 91% LW

Comparing the new area with the original area:

100% LW- 91% LW= 9% LW

∴ The area will decrease by 9%.

*Note that percentage is equivalent to dividing a number by 100.

work out the volume of cylinder B

Answers

Answer:

720cm³

Step-by-step explanation:

Volume of a cylinder is given by Base Area (A) x Height (h)

or V = Ah

Volume of cylinder A = 18 x 5 = 90 cm³

Base Area A = πr² where r is the radius of the base

For cylinder A, if radius = rₐ

Area = π x (rₐ)² = 18

We can see that cylinder B has twice the height of cylinder A. That means cylinder B radius is twice the radius of cylinder A

So radius of cylinder B = 2 x rₐ = 2rₐ

Base Area of Cylinder B = π x (2rₐ)² = 4π(rₐ)² = 4 x Base Area of cylinder A = 4 x 18 = 72

So while the heights are in the ration 1:2, the base areas are in the ratio 1:4 because the areas are directly proportional to the square of the radius

Hence Volume of Cylinder B = 72 x 10 = 720 cm³

Another way to look at this is that the volume of cylinder B = 8 (2 x 2 x2) times the volume of cylinder A = 8 x 90 = 720cm³

Answers

When Mr. Johnson earns $5.40 an hour. One week, he worked 40 hours and 2 hours overtime, If he is paid time and one-half for overtime then the total amount he earned is $232.2

The amount he earns in an hour = $5.40

Total number of hours he worked =40 hours

The amount he earns = 5.40×40 = $216

Overtime hours = 2 hours

Overtime payment per hour= 5.40×1.5= $8.1

The amount he earns for overtime = 2×8.1= $16.2

The total amount he earned = 216+16.2= $232.2
