Step-by-step explanation:
helppppp meeeeee the sum of the squares of three consecutive integer numbers is 1454. Find the numbers. but i found 21 22 and 23. you need to find the other set plzzz
Step-by-step explanation:
A=x
B=x+1
C=x+2
[tex] {x}^{2} + {(x + 1)}^{2} + {(x + 2)}^{2} = 1454 \\ {x}^{2} + {x}^{2} + 2x + 1 + {x}^{2} + 4x + 4 = 1454 \\ 3{x}^{2} + 6x + 5 - 1454 = 0 \\ 3 {x}^{2} + 6x - 1449 = 0 \\ {x}^{2} + 2x - 483 = 0 [/tex]
I'm sorry but I can't use the calculator, I hope this helps you anyway.
Answer:
The two sets would be 21,22,23 and -21, -22, and -23
Step-by-step explanation:
This is because a negative number squared would be positive.
So -21^2+-22^2+-23^2 would equal the same as 21^2+22^2+23^2 which would be 1454.
what is 8 (x/4 - 6) < 4
Answer:
x<26
Step-by-step explanation:
8(x/4 - 6) < 4
Divide both sides by 8;
8(x/4 - 6)/8 < 4/8
Simplify;
x/4-6<1/2
Add 6 to both sides;
x/4-6+6<1/2+6
Simplify;
x/4-6+6<1/2+6
Simplify
x/4-6+6
=x/4
Simplify;
1/2+6
Convert it into a fraction;
6*2/2+1/2
Since the denominators are equal combine the fractions;
6*2+1/2
6*2+1=13
=13/2
x/4<13/2
Multiply both sides by 4;
4x/4<13*4/2
Simplify 4x/4
4x/4
4/4=1
=x
Simplify 13*4/2
Multiply the numbers:13*4=52
=52/2
Divide the numbers:52/2=26
=26
x<26

Where would the last point need to be in order to finish graphing a square using the points ( 1, 3) 5,3 and 5,7?
A. (3, 7
B. 1, 5
C 1, 7
D. 5, 1
Answer:
C
Step-by-step explanation:
A study that looked at beverage consumption used sample sizes that were much smaller than previous national surveys. One part of this study compared 20 children who were 7 to 10 years old with 5 who were 11 to 13. The younger children consumed an average of 8.2 oz of sweetened drinks per day while the older ones averaged 14.1 oz. The standard deviations were 10.8 oz and 8.2 oz respectively.
Required:
Do you think that it is reasonable to assume that these data are Normally distributed? Explain why or why not?
Answer:
Step-by-step explanation:
In statistics, about 68 percent of values come in one standard deviation of the mean by using a standard normal model. Approximately 95% of the data were all within two standard deviations from the mean. Almost all of the data are in the range of three standard deviations of the mean (roughly 99.7%).
The 68-95-99.7 law, also known as the Empirical Rule, is based on this evidence. 68 percent of the data values of a naturally distributed data collection of small children with a mean of 8.2 and a standard deviation of 10.8 would be between -2.2 and 19.0.
Within a mean of 14.1 as well as a standard deviation of 8.2, 68 percent of the data values in a usually distributed data collection of older children would be between 5.9 and 22.3.
However, we cannot conclude that the data is naturally distributed since the real actual data vary from the usual normal curve computed above.
Hence, various measures like either goodness of fit or theory testing, would be used for this.
Please help me! This is due tomorrow and I really need some help! Thank you.
Answer:
B. the mean is 59 inches
Step-by-step explanation:
if you add the number of inches together you get 413. 413 divided by 7 is 59. that is the mean.
Answer:
B: The mean wingspan is 59 inches.
Step-by-step explanation:
The mean is the average so when you add up all of the wingspans 53+59+59+60+60+61+61 you get 413, and to find the mean you would divide that by seven (413/7), because there are 7 students, which is 59.
A Mustang GT on Missouri has a marked price of $60,000. If paid in cash you are to pay 15% less than the marked price. It also have a hire purchase plan which states to pay 30% of the marked price and $1000 monthly payments for 4 yrs.
A) Discount on Cash price.
B) Cash Price.
C) Amount Payable.
D ) Hire Purchase Price
E ) Difference between the Hire Purchase price and the Cash Price.
Answer:
A) Discount on Cash price. ($9,000 )
B) Cash Price. ($51,000 )
C) Amount Payable. ($51,000 )
D ) Hire Purchase Price ($66,000 )
E ) Difference between the Hire Purchase price and the Cash Price. ($15,000 )
Step-by-step explanation:
The following is the workings:
The GT Missouri marked price = $60,000
If paying cash,
Discount = 15%
(15/ 100 ) x $60,000 = $9,000
Actual Price (less discount) = $60,000 - $9000 = $51,000
If hire purchase,
Firstly, 30% marked price,
= (30/100) x $60,000 = $18,000
Monthly payment = $1000
Period = 4 years = 4 x 12 = 48 months
Total monthly payment,
$1000 x 48 = $48, 000
Therefore, total hire purchase payment
Monthly payment + initial 30% payment
= $18,000 + $48,000 = $66,000
Difference between hire purchase and cash price,
= $66,000 - $51,000 = $15,000

A school secretary plans to order 510 sandwiches for a school picnic. He asks 85 randomly selected students which type of sandwich is their favorite. Based on the data from the sample, how many of each type of sandwich should the secretary order? Show your work.
Sandwich type quantity
penutbutter 37
Ham 18
egg salad 5
Turkey 25
Answer:
85 will be the answer
Step-by-step explanation:
please mark as braillenest
Answer:
Step-by-step explanation:
510/85 = 6
Sandwich type quantity
penutbutter 37 X 6 = 222
Ham 18 X 6 = 108
egg salad 5 X 6 = 30
Turkey 25 X 6 = 150
222 + 180 + 30 + 150 = 510
A triangle has side lengths of 25in, 30in, and 50 in. Classify it as acute, obtuse, or right. Please help me.
9514 1404 393
Answer:
obtuse
Step-by-step explanation:
Using the idea of a "form factor", we find ...
f = a² + b² - c²
f = 25² +30² -50² = 625 +900 -2500 = -975
The form factor is negative, so the triangle is obtuse.
_____
Additional comment
The form factor, as defined above, classifies the triangle according to its sign:
f > 0 . . . acute
f = 0 . . . right
f < 0 . . . obtuse
The largest angle in the triangle can be found from ...
cos(C) = f/(2ab)
Here, it is C = arccos(-975/1500) ≈ 130.5416°

A) Determine the mistake
B) Determine the correct answer.
- 2x -4>8
-2x - 4+4>8+4
-2x >12
- 2x/2 > 12 /2
x>-6
Answer:
She forgot to multiply both sides by -1 and reverse the inequality. She also didn't flip the signs.
Step-by-step explanation:
- 2x -4>8
-2x - 4+4>8+4
-2x >12
(-2x)(-1)<12(-1)
2x<-12
2x/2<-12/2

9514 1404 393
Answer:
1 1/6 hours
Step-by-step explanation:
Assuming distance and time are proportional, 2/3 of the 1 3/4 hours remain:
(2/3)(7/4) = 14/12 = 1 1/6 . . . . hours remain
The trip will take 1 1/6 hours longer.

Explain how to tell 202/220 is not in simplest form
Answer:
An easy way to tell with a number like this is that both numbers are round, so they can both be divided by 2
Step-by-step explanation:
You can tell that it is not simplified if they are both even, as they can be divided by 2, or really, if both numbers have a common factor as a divisor.
For example, 3/6 has a common of factor by 3, 3/3 / 3/6 = 1/2.

Answer:
$33.75
65%
$13.78
Step-by-step explanation:
commission earned = percentage commission x worth of goods sold
4 1/2% x $750
4.5% x $750
0.045 x $750 = $33.75
Percentage mark-up = [(selling price - cost price) / cost price] x 100
[(90.75 - 55) / 55) x 100
= 65%
new income = 6% of $13 + 13
0.06 x 13 = $0.78
$13 + $0.78 = $13.78
FinD the 50th term of the sequence defined by the sequence 3n+3????
Answer:
[tex]\huge {\purple {a_{50} = 153}} [/tex]
Step-by-step explanation:
Given sequence is 3n + 3
[tex] \implies a_n = 3n + 3[/tex]
Plug n = 50
[tex] \implies a_{50} = 3(50) + 3[/tex]
[tex] \implies a_{50} = 150 + 3[/tex]
[tex]\huge {\red {\implies a_{50} = 153}} [/tex]
We have ,
=> T_n = a + ( n - 1)d
=> T₅₀ = 3n + 3
=> T₅₀ = 3(50) + 3
=> T₅₀ = 150 + 3
=> T₅₀ = 153
THEN FIND THE VALUE OF X
Answer:
Supplementary
x = 31
Step-by-step explanation:
The given angles are supplementary which means their sum is equal to 180
3x + 25 + 2x = 180 add like terms
5x + 25 = 180 subtract 25 from both sides
5x = 155 divide both sides by 5
x = 31
