Answer:
The smallest integer is -4.
Step-by-step explanation:
4(n + n+2) = 3*n - 12 Combine the left
4(2n + 2) = 3n- 12 Remove the brackets
8n + 8 = 3n - 12 Subtract 3n from both sides
8n-3n + 8 = 3n-3n - 12 Combine
5n + 8 = - 12 Subtract 8 from both sides
5n = - 12 - 8
5n = - 20 Divide by 5
5n/5 = -20/5
n = - 4
n + 1 = -3
n + 2 = - 2

If the pattern shown continues how many black keys appear on a keyboard with 35 white keys ?
Answer:
25 black keys
Step-by-step explanation:
Let the number of requires black keys = 'x'
White key : Black keys = 7 : 5
7 : 5 :: 35 : x
Product of extremes = product of means
7 *x = 35 * 5
x = [tex]\frac{35*5}{7}[/tex]
x = 5 *5
x = 25
Katie just opened a checking account at the bank. Within the first month, she deposited three checks for $21.68, $42.09, and $65.44. She withdrew $4.64 for new pencils, $23.11 for earbuds, and $9.78 for movies from her account in the same month.
Complete question is;
Katie just opened a checking account at the bank. Within the first month, she deposited three checks for $21.68, $42.09, and $65.44. She withdrew $4.64 for new pencils, $23.11 for earbuds, and $9.78 for movies from her account in the same month.
Write Katie’s withdrawals as negative rational numbers and her deposits as positive rational numbers.
Answer:
Deposits are; +21.68, +42.09, and +65.44.
Withdrawals are; -4.64, -23.11, and -9.78
Step-by-step explanation:
We are told that the deposits are;
$21.68, $42.09, and $65.44.
Now, she withdrew $4.64 for new pencils, $23.11 for earbuds, and $9.78 for movies from her account in the same month.
We are told to write Katie’s withdrawals as negative rational numbers and her deposits as positive rational numbers.
A rational number is a number that can be expressed as the ratio of two integers. In this question, by inspection, all the given values for deposits and withdrawals can be expressed as the ratio of 2 integers.
Thus;
Deposits are; +21.68, +42.09, and +65.44.
Withdrawals are; -4.64, -23.11, and -9.78
What are the x-intercepts of this quadratic function? g(x) = - 2(x - 4) * (x + 1)
A. (- 4, 0) and (- 1, 0)
B. (4, 0) and (- 1, 0)
C. (- 4, 0) and (1, 0)
D. (4, 0) and (1, 0)
Hi,
The correct answer is B.
The equation is g(x) = -2(x − 4)(x + 1).
In this equation (x - 4) and (x + 1) are the x-intercepts. In this form (x - 4) and (x + 1) are zeros.
Therefore the x-intercepts are (4,0) and (-1,0).

A right triangle has side 9 and hypotenuse 15. Use the Pythagorean Theorem to find the length of the third side.
Provide your answer below:
Answer:
12
Step-by-step explanation:
Pythogorean Theorem:
a squared + b squared = c squared
9 squared or 81 + ? squared = 15 squared or 225
Inverse Pythagorean Theorem:
c squared - a squared = b squared
225 - 81 = 144
sqrt (144) = 12
12 = b
Hope this helps! Good luck!

In a random sample of 100 voters, 48 said they planned on voting for the Republican presidential candidate. On election day, 51% of voters actually voted for the Republican presidential candidate. (a) Identify the value of the sample proportion.
Answer: 0.48 .
Step-by-step explanation:
The sample proportion is a ratio of number of successes in a sample to the sample size.Let p be the proportion of voters actually voted for the Republican presidential candidate.
Given: In a random sample of 100 voters, 48 said they planned on voting for the Republican presidential candidate.
Sample proportion: [tex]\hat{p}=\dfrac{48}{100}=0.48[/tex]
Hence, the sample proportion is 0.48 .

Can someone factor f(x)= 2x^4 -12x^3 +6x +20x and please show steps thank you
Answer:
I dont think the way you wrote it was right.
Step-by-step explanation:
Answer:
f(x) = 2x(x - 5)(x -2)(x + 1)Step-by-step explanation:
Given
f(x)= 2x^4 -12x^3 +6x^2 +20xFactoring in steps
f(x)= 2x^4 -12x^3 +6x^2 +20x =2x(x^3 - 6x^2 + 3x + 10) =2x(x^3 - x^2 - 2x - 5x^2 + 5x + 10)2x(x - 5)( x^2 - x - 2) = 2x(x - 5)(x -2)(x + 1)If a data set is negatively skewed, which would be the best measure of spread? Select one:
Interquartile Range
Standard Deviation
Range
Answer:
Not real sure, but it should be Standard Deviation, if a data set is negatively skewed it would need a good measure for data spread.
The residual for a predicted relative abundance when the rainfall was 3 inches is 1.25. What is the actual relative abundance when the rainfall was 3 inches
Answer:
The actual relative abundance will be "7.59".
Step-by-step explanation:
The residual on something like a curve anywhere at a point becomes expressed as the maximum at either the position between some of the real y-value as well as the expected y-value. Consequently, the difference regarding true relative abundance as well as expected relative abundance seems to be 1.25 whether we presume that the x-variable represents rainfall, as well as they-variable, represents the relative abundance of locusts.The predicted relative abundance for 3 inches rainfall will be:
= [tex]6.7 - (0.12\times 3)[/tex]
= [tex]6.34[/tex]
The residual will be:
= [tex]actual - predicted \ relative \ abundance[/tex]
= [tex]1.25[/tex]
Now,
The actual relative abundance will be:
= [tex]1.25 + predicted \ relative \ abundance[/tex]
= [tex]1.25 + 6.34[/tex]
= [tex]7.59[/tex]
Remember that perhaps the residual positive value means that even the calculation underestimates the relative abundance. The real relative abundance, however, is 7.59.
