The percent of decrease from 69 songs to 37 songs?
Answer:
46.3768%
Step-by-step explanation:
Or 46.38% if you round it to the nearest tenths
The percentage decrease of songs from 69 to 37 songs is 46.4%.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, The number of songs decreased from 69 songs to 37 songs.
Therefore, The net amount of songs that decreased is,
= (69 - 37).
= 32 songs.
Now to obtain percentage change we'll divide the net amount change by the original amount and multiply it by 100% which is,
= (32/69)×100.
= 46.4%

Answer:
81
Step-by-step explanation:
First we go with exponents, 2x2=4 and 5x2=25. Now we go with what's inside the parentheses so, 4 (Originally 2x2) plus 4 plus 6, which equals 14. Now we multiply 4 and 14, which equals 56. Then we add 56 and 25 which equals 81.

Find the difference in the given lengths of the polygons . (7x + 2) units (6x - 5) units .
Answer:
Difference in the lengths of the polygons is (x + 7) units.
Step-by-step explanation:
Lengths of the given polygon = (7x + 2) units and (6x - 5) units
Therefore, difference in the given lengths = (7x + 2) - (6x - 5)
= (7x - 6x) + (2 + 5)
= x + 7
Therefore, difference in the lengths of the polygons is (x + 7) units.

What is the expression of (5)(x+3)(y+2)
Answer:
The expression of (5)(x+3)(y+3) is a binomial
i need help finding the y-intercept
Answer: (0, -7)
Step-by-step explanation:
y = mx + b
Where m is slope and b is y-intercept
y = 2x + b
One point that passes through the line is (5,3), which means that x = 5 and y = 3
3 = 2(5) + b
3 = 10 + b
b = -7
(0, -7) is the y-intercept
Using this info you can find the equation of the line

Construct a 90% confidence interval for μ1-μ2 with the sample statistics for mean calorie content of two bakeries' specialty pies and confidence interval construction formula below. Assume the populations are approximately normal with equal variances.
Answer:
The 90% confidence interval for the difference in mean (μ₁ - μ₂) for the two bakeries is; (49) < μ₁ - μ₂ < (289)
Step-by-step explanation:
The given data are;
Bakery A
[tex]\overline x_1[/tex] = 1,880 cal
s₁ = 148 cal
n₁ = 10
Bakery B
[tex]\overline x_2[/tex] = 1,711 cal
s₂ = 192 cal
n₂ = 10
[tex]\left (\bar{x}_1-\bar{x}_{2} \right ) - t_{c}\cdot \hat \sigma \sqrt{\dfrac{1}{n_{1}}+\dfrac{1}{n_{2}}}< \mu _{1}-\mu _{2}< \left (\bar{x}_1-\bar{x}_{2} \right ) + t_{c}\cdot \hat \sigma \sqrt{\dfrac{1}{n_{1}}+\dfrac{1}{n_{2}}}[/tex]
df = n₁ + n₂ - 2
∴ df = 10 + 18 - 2 = 26
From the t-table, we have, for two tails, [tex]t_c[/tex] = 1.706
[tex]\hat{\sigma} =\sqrt{\dfrac{\left ( n_{1}-1 \right )\cdot s_{1}^{2} +\left ( n_{2}-1 \right )\cdot s_{2}^{2}}{n_{1}+n_{2}-2}}[/tex]
[tex]\hat{\sigma} =\sqrt{\dfrac{\left ( 10-1 \right )\cdot 148^{2} +\left ( 18-1 \right )\cdot 192^{2}}{10+18-2}}= 178.004321469[/tex]
[tex]\hat \sigma[/tex] ≈ 178
Therefore, we get;
[tex]\left (1,880-1,711 \right ) - 1.706\times178 \sqrt{\dfrac{1}{10}+\dfrac{1}{18}}< \mu _{1}-\mu _{2}< \left (1,880-1,711 \right ) + 1.706\times178 \sqrt{\dfrac{1}{10}+\dfrac{1}{18}}[/tex]
Which gives;
[tex]169 - \dfrac{75917\cdot \sqrt{35} }{3,750} < \mu _{1}-\mu _{2}< 169 + \dfrac{75917\cdot \sqrt{35} }{3,750}[/tex]
Therefore, by rounding to the nearest integer, we have;
The 90% C.I. ≈ 49 < μ₁ - μ₂ < 289
Solve the system of equations
-12x+9y=7
3x+4y=2
Show all workings please
Answer:
x = -2/15 & y = 3/5
Step-by-step explanation:
- 12x + 9y = 7 ...(1) ; 3x + 4y = 2 ...(2)
Multiply both sides of (2) by 4:
12x + 16y = 8
Add the new equation & (1):
12x + 16y = 8
-12x + 9y = 7
0 + 25y = 15 => y = 15/25 = 3/5
Thus, substitute the value of y in (2):
3x + 4y = 2 => 3x = 2 - 4(3/5) = (10-12)/5
=> 3x = -2/5
=> x = - 2/15
Answer:
[tex]x=-\frac{2}{15}=-0.133333333\\y = \frac{3}{5}= 0.6[/tex]
Step-by-step explanation:
−12x+9y=7
3x+4y=2
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
−12x+9y=7,3x+4y=2
To make −12x and 3x equal, multiply all terms on each side of the first equation by 3 and all terms on each side of the second by −12.
3(−12)x+3×9y=3×7,−12×3x−12×4y=−12×2
Simplify.
−36x+27y=21,−36x−48y=−24
Subtract −36x−48y=−24 from −36x+27y=21 by subtracting like terms on each side of the equal sign.
−36x+36x+27y+48y=21+24
Add −36x to 36x. Terms −36x and 36x cancel out, leaving an equation with only one variable that can be solved.
27y+48y=21+24
Add 27y to 48y.
75y=21+24
Add 21 to 24.
75y=45
Divide both sides by 75.
y=3/5
Substitute 3/5 for y in 3x+4y=2. Because the resulting equation contains only one variable, you can solve for x directly.
3x+4×(3/5)=2
Multiply 4 times 3/5
3x+12/5=2
Subtract 12/5 from both sides of the equation.
3x=-2/5
Divide both sides by 3.
x=-2/15
The system is now solved.
x=−2/15 ,y=3/5
