2. French Vanitta K-Cups that originally
cost $5.99 are now on sale for $4.75.
Answer:
20.7% is the % decrease.
Step-by-step explanation:
If you are finding the % of decrease then see below.
% Decrease = (Original Cost - New Cost ) ÷ Original Cost × 100
5.99 - 4.75 = 1.24
1.24 ÷ 5.99 = .2070
.2070 × 100 = 20.7%
The cost of a baguette and a cup of hot chocolate is $1.45. The cost of 2 baguettes and a cup of hot chocolate is $2.10. What is the cost of one cup of hot chocolate?
Answer:
It is $0.8
Step-by-step explanation:
First find out the value of one baguette.
They just added one more baguette. So the amount left after subtracting them both will be the cost of 1 baguette.
2.10 - 1.45 = 0.65
Now, subtract the 1st cost with the cost of 1 baguette.
1.45 - 0.65 = $0.8

To solve for k in the inequality -16 -32 > -48, what steps are correct?:
A First, subtract 32 to each side, then divide by -16 and flip the sign
B First, divide both sides by 16, then add 32 to both sides and leave
the sign
C First, subtract 48 from both sides, divide by -16 and leave the sign
D First, add 32 to both sides, then divide by -16 and flip the sign
Answer:
D. First, add 32 to both sides, then divide by -16 and flip the sign
Step-by-step explanation:
Taking that the inequality is -16k-32>-48
First you have to get rid of any addition or subtraction, in this case you have to get rid of -32 by adding 32 to each side:
-16k-32+32 > -48 +32
Then you need to divide by -16 and flip the sign because you are dividing by a negative number and if you don't flip the sign the inequality will be false.
[tex]\frac{-16k}{-16} <\frac{-16}{-16}[/tex]

What is the product?
(x − 3)(2x2 − 5x + 1)
2x3 − x2 + 16x + 3
2x3 − 11x2 + 16x + 3
2x3 − 11x2 + 16x − 3
2x3 − x2 + 16x − 3
Step-by-step explanation:
= (x - 3)(2x² - 5x + 1)
= 2x³ - 5x² + x - 6x² + 15x - 3
= 2x³ + (-5 - 6)x² + (1 + 15)x - 3
= 2x³ - 11x² + 16x - 3
Option → C
The product of the given polynomials is: C. 2x³ - 11x² + 16x - 3.
What is the Product of Two Polynomials?The product of two polynomials is simply the multiplication of both polynomials together.
Given:
(x − 3)(2x² − 5x + 1)
Multiply using the distributive property
x(2x² − 5x + 1) -3(2x² − 5x + 1)
2x³ - 5x² + x - 6x² + 15x - 3
Combine like terms
2x³ - 11x² + 16x - 3
Therefore, the product of the given polynomials is: C. 2x³ - 11x² + 16x - 3.

In which set do all of the values make the inequality 3k – 6 < 12 true?
The set of values that satisfies the inequality is (-∝, 6)
Inequality shows the non-equal comparison between two numbers or other mathematical expressions.
Given the inequality: 3k – 6 < 12
Solving the inequality:
3k – 6 < 12
Add 6 to both sides:
3k - 6 + 6 < 12 + 6
3k < 18

Answer:
25% increase
Step-by-step explanation:
formula for percent of change = (new amount - original amount) / original amount; this will give you a decimal and multiply it by 100 to get the percent
(30 - 24) / 24
6/24 = 1/4 = 0.25

A National Institute of Health survey of 40467 U.S adults found that 3156 of them experienced at least one major depressive episode in the previous year. Make a 95% confidence interval for the proportion of all U.S. adults who experienced depression in that year. (Source: https://www.nimh.nih.gov/health/statistics/major-depression)
Using the information given, it is found that the 95% confidence interval for the proportion of all U.S. adults who experienced depression in that year is (0.075, 0.081).
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]\frac{1+\alpha}{2}[/tex].
3156 out of 40467 adults experienced depression, hence:
[tex]n = 40467, \pi = \frac{3156}{40467} = 0.078[/tex]
95% confidence level
So [tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.078 - 1.96\sqrt{\frac{0.078(0.922)}{40467}} = 0.075[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.078 + 1.96\sqrt{\frac{0.078(0.922)}{40467}} = 0.081[/tex]
The 95% confidence interval for the proportion of all U.S. adults who experienced depression in that year is (0.075, 0.081).

GIVEN THAT TAN Ꝋ= - 4/3 AND Ꝋ IS IN QUADRANT II, FIND SIN 2Ꝋ
Answer:
sin 2θ = -24/25
Step-by-step explanation:
see the below formula of sin x in terms of tan x
by substituting => -4/3 / ± √(16/9 + 1)
=> -4/3 / ± √(25/9)
=> -4/3 / ± 5/3
=> ± -4/5
=> ± 4/5
as theta is in second quadrant is in 2nd quadrant sin value is positive
so sin θ = 4/5 and cos θ = -3/5
now sin 2θ = 2 sinθcosθ
= 2 * 4/5 * -3/5
= -24/25
