How do you factor the sum of cubes of 216s³+ 27t³?
You can not make the sum of two unalike terms.
Vector you equals (-3,8), and vector v=(-14,6) match each vector operation with the magnitude of its resultant vector
drag the tiles to the boxes to form the correct pairs not all tiles will be used
Answer:
I hope this helps you
Step-by-step explanation:
The magnitude of given operations of vectors are found.
What are Vectors?Vectors are quantities which are having the independent properties of magnitude as well as direction.
Given that,
u = (-3, 8) and v = (-14, 6)
3u = (-9, 24) and 2v = (-28, 12)3u - 2v = (-9+28, 24-12) = (19, 12)
Magnitude of 3u - 2v = [tex]\sqrt{19^2+12^2}[/tex] = [tex]\sqrt{505}[/tex] units
2u = (-6, 16) and 3v = (-42, 18)2u - 3v = (36, -2)
Magnitude = [tex]\sqrt{36^2+(-2)^2}[/tex] = [tex]\sqrt{1300}[/tex] units
u = (-3, 8) and 4v = (-56, 24)u + 4v = (-59, 32)
Magnitude = [tex]\sqrt{(-59)^2+32^2}[/tex] = [tex]\sqrt{4505}[/tex] units
5u = (-15, 40) and v = (-14, 6)5u - v = (-1, 34)
Magnitude = [tex]\sqrt{1157}[/tex] units
7u = (-21, 56) and 2v = (-28, 12)7u - 2v = (7, 44)
Magnitude = [tex]\sqrt{1985}[/tex] units.
Hence the magnitude of vectors are found.

A party of 5 wants to add a tip of 20% to their total $175 bill
Answer:
Hi, I think your question is incomplete. But I'll assume you're asking a party of 5 wants to add a tip of 20% to their total 175 dollars bill, how much do each person needs to pay?
Step-by-step explanation:
Firstly, calculate the percentage: 175 x 20% is 35, so 35 + 175 is 210.
210 ÷ 5 (Num. Of people in party)
Is 42 dollars. Therefore each people need to pay 42 dollars.

Answer:
d. x > -2
Step-by-step explanation:
okay lets simplify this equation
-6x + 18 < 30
first lets subtract 18 from both sides
-6x < 12
now divide both sides by -6
x < -2
important rule: when you multiply or divide an inequality by a negative number, you must flip the inequality sign!
x > -2

A student wants to determine if there is a difference in the pricing between two stores for health and beauty supplies. She recorded prices from both stores for each of 10 different products. Assuming that the conditions for conducting the test are satisfied, determine if there is a price difference between the two stores.
alpha = 0.05 level of significance.
Store 1 Store 2
Product A 5.92 5.85
Product B 7.53 7.93
Product C 3.75 3.98
Product D 1.81 1.71
Product E 1.71 1.96
Product F 2.86 2.58
Product G 4.79 4.74
Product H 3.18 3.69
Product I 3.02 2.87
Product J 3.77 3.68
Required:
a. Use technology to calculate the P-value.
b. Draw a conclusion based on the hypothesis test.
Answer:
The P-value is 0.04542 which is less than 0.05
Since the calculated value of t does not fall in the critical region so we accept H0 that there is no price difference between the two stores.
Step-by-step explanation:
Store 1 Store 2 Difference (Store 2-1) d²
Product A 5.92 5.85 -0.07 0.0049
Product B 7.53 7.93 0.4 0.16
Product C 3.75 3.98 0.23 0.0529
Product D 1.81 1.71 -0.1 0.01
Product E 1.71 1.96 0.25 0.0625
Product F 2.86 2.58 - 0.28 0 .0784
Product G 4.79 4.74 -0.05 0.0025
Product H 3.18 3.69 0.51 0.2601
Product I 3.02 2.87 - 0.15 0.0225
Product J 3.77 3.68 -0.09 0.0081
∑ 0.65 0.6619
1. The degrees of freedom = n-1= 10-1= 9
2. The significance level is 0.05
3.The test statistic is
t= d`/sd/√n
4. The critical region is ║t║≥ t (0.025,9) = 2.262
The null and alternate hypotheses is
H0 : ud= 0 against Ha: ud≠ 0 (two tailed test)
5. Calculations
d`= ∑di/n= 0.65/10= 0.065
Sd²= ∑(di-d`)²/n-1 = 1/n-1 [∑di²- (∑di)²n]
Sd²= 1/9[0.6619-(0.65)²/10] = [0.6619-0.4225/9]= 0.0266
Sd= 0.163
Therefore
t= d`/ sd/√n
t= 0.065/ 0.163/√10
t= 0.3987/3.1622=0.1261
6. Conclusion
Since the calculated value of t does not fall in the critical region so we accept H0 that there is no price difference between the two stores.
Now the P- value:
The P-value is the rejection region. In this test it is on both sides and would add up to be (2.262 + 2.262)/100= 4.542/100
The P-value is 0.04542 which is less than 0.05

Answer:
Step-by-step explanation:
Total number of students who roller skated = 80
Number of students who roller skated with laser tag = 39
Number of students who roller skated with no laser tag = 80 - 39 = 41
Therefore, percentage of students who roller skated with no laser tag = [tex]\frac{41}{154}\times 100[/tex] = 27%
Since, number of students who played laser tag = 85
Percentage of students who played laser tag = [tex]\frac{85}{154}\times 100[/tex] = 55%
Total number of students who played no laser tag = 45% of 154 = 69
Number of students with no roller skates and no laser tag = 69 - 41 = 28
Percentage of students with no roller skates and no laser tag = [tex]\frac{28}{154}\times 100[/tex]
= 18%
Percentage of students who played with no rollers skates = (30 + 18)%
= 48%
Laser tag No laser tag Total
Roller skate 25% 27% 52%
No Roller skate 30% 18% 48%
Total 55% 45% 100%

Please help solve question 12 and through 14
( will give brianlst :))
Answer:
12. The slope is 2
The y-intercept is 5
13. The slope is 1
The y-intercept is 5
14. The slope is 0.99
The y-intercept is 10
Step-by-step explanation:
12. If you use the rise over run method you go up by 2 and over 1. If you put rise over run you get 2/1 and that is equal to 2. So, slope is 2. The y-intercept is where x=0. If you look you can see that when x is 0, y is equal to 5. Therefore, the y-intercept is 5.
13. The slope is 1 because if you use the slope formula you can use two points like (1,6) and (2,7) in it to find that the slope is 1. You can also see that both the x and y variables go up by 1 each time, so the slope has to be 1. Once again the y-intercept is where x equals 0, even though it isn't shown on the graph we can infer it. At 0 days, the length of the kudzu would be 5 (because 5 is one step less than 6, remember the slope is 1).
14. The slope would have to be 0.99 because each consecutive download is 99 cents. There is a base membership fee of $10 so that has to be the y-intercept.
I hope this helps!!

Solve for Y
ABC = DEF
Answer:
12
Step-by-step explanation:
△ABC ≅ △DEF means that these two triangles are congruent to each other. Congruent triangles also have corresponding sides and angles that are equal to each other!
This means that angle A corresponds to angle D; and thus, we can set up in equation for these two to solve for y.
First, let's try to decipher what exactly we are solving. Y is what we are multiplying by five to get 60°, or angle A (congruent angle).
Now, we just solve it!

Answer:
The temperature farthest from zero is 5
Step-by-step explanation:
the reason for this is because it doesn't matter whether that temperature is negative or positive because all the question is asking is...."how far from zero"....and would -4 be farther from zero....or would 5 be farther from zero. How I know this is absolute value is always positive. And absolute value of -4....is 4.....and absolute value of 5....is 5.
And 5 is 1 temperature more away from zero than -4.
Answer:
5 is the farthest from 0
-4 is the coldest temperature
5 is the warmest temperature
Step-by-step explanation:
The farthest from 0 could be negative or positive. It's just whichever one has the greatest absalute value (if you know that term, if not...), whichever one you would put up more fingers to count to.
In this case, according to the number line, the farthest from 0 into the nagatives is -4, but the farthest from 0 in the positives is 5. This means that 5 is the farthest from 5 because 5 takes 5 of your fingers to count to, whule -4 (yes, even though it's negative) takes just 4 fingers. This is a good way to visualize it until you can wrap your head around it!
The coldest is the lowest number. In this case, it's below zero. Below zero means negatives. In this case, -4 is the lowest number.
The warmest is the highest number. In this case, it's above zero. That means it's a positive number. 5 is the highest number here.
