Answer:
18 students
Step-by-step explanation:
72 boys
90 girls
objective: to arrange in rows with equal number (n) of only boys or girls.
To find the maximum number (n) of boys or girls in each row, you need to find the GCF (Greatest Common Factor) of the numbers 72 and 90, such that n divides both numbers evenly without a remainder.
objective: to arrange in rows with an equal number (n) of only boys or girls.
To find the maximum number (n) of boys or girls in each row, we need to find the GCF (Greatest Common Factor) of the numbers 72 and 90, such that n divides both numbers evenly without a remainder.
We will use two methods to find the GCF of two numbers.
Factorize each number to powers of prime and locate the common factors.
72= 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72
90= 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45 and 90
So the GCF/your answer is 18.

Hamdah wants to save $500 to buy a TV. She saves $17 each week. The amount, A (in dollars), that she still needs after w weeks is given by the following function. =Aw−50017w Answer the following questions. (a) If Hamdah still needs $211, how many weeks has she been saving? weeks (b) How much money does Hamdah still need after 5 weeks? $
Answer:
(a) 14.11 dollars (b) 204 dollars
Step-by-step explanation:
(a) 500 - 211 = 289 289 '/. 17 = 14 r:7 14.7 dollars
(b) 17 x 5 = 85 289 - 85 = 204
hope this helped :)
Answer:
If Hamdah still needs $211, she has been saving for 17 weeks(17b). Hamdah still needs $126 after 5 weeks
Step-by-step explanation:
Subtract $211 from $500, you will get $289. After you must divide $289 by 17 because Hamdah earns $17 each week, you will get 17 and that represents how many weeks she has been saving. Hamdah still needs $126 because taking the information from the last question she has $289 (289+211 equals 500, 211 is how much she needs and 289 is how much she has) so we subtract 289 from 500 and we will get 211, then you subtract the product of $17 × 5 weeks from 211 and you will get $126. So, after 5 weeks, Hamdah will still need $126.

Mike earned $11.75 per hour yesterday. He worked a total of 8.2 hours last week. How much money did Mike earn yesterday?
An electronics company has a contract to deliver 21,475 radios within the next four weeks. The clientis willing to pay $20 for each radio delivered by the end of the first week, $18 for those delivered by theend of the second week, $16 by the end of the third week, and $14 by the end of the fourth week. Sinceeach worker can assemble only 50 radios per week, the company cannot meet the order with its presentlabor force of 40; hence it must hire and train temporary help. Any of the experienced workers can betaken off the assembly line to instruct a class of three trainees; after one week of instruction, each of the trainees can either proceed to the assembly line or instruct additional new classes.
At present, the company has no other contracts; hence some workers may become idle once the delivery is completed. All of them, whether permanent or temporary, must be kept on the payroll 'til the end of the fourth week. The weekly wages of a worker, whether assembling, instructing, or being idle, are $200; the weekly wages of a trainee are $100. The production costs, excluding the worker's wages, are $5 per radio. The company's aim is to maximize the total net profit.
Required:
Formulate this as an LP problem (not necessarily in the standard form).
Step-by-step explanation:
See attached a detailed annotation of the LP formulation
let is describe the problem bellow.
An electronics company has a contract to deliver 21,475 radios within
the next four weeks. The client is willing to pay
$20 for each radio delivered by the end of week 1
$18 for each radio delivered by the end of week 2
$16 for each radio delivered by the end of week 3
$14 for each radio delivered by the end of week 4
Each worker can assemble 50 radios/wk.
Size of present workforce = 40.
Any experienced worker can be taken off the assembly line to instruct a class
of three trainees; after one week of instruction, each of the trainees can
either proceed to the assembly line or instruct additional new classes.
Weekly wages for experienced workers: $200
Weekly wages for trainees: $100
Production costs, excluding wages: $5/radio.

__________ refers to the degree of correlation among independent variables in a regression model. a. Multicollinearity b. Tolerance c. Rank d. Confidence level
Answer:
Option A: Multicollinearity
Step-by-step explanation:
Multicollinearity is said to be present when there are high correlations between two or more independent variables called predictor variables. In simple terms, Multicollinearity refers to when the independent variables present in a regression model are correlated.
Tolerance is simply used to detect Multicollinearity.
Rank is basically the model in which the ranks of the dependent variable are said to have regressed on a set of characteristics in the experiment known as covariates.
Confidence level is the percentage of all possible samples that we can expect to be included within the true population parameter.
Looking at all the definitions, the one that fits with the statement in the question is Multicollinearity.

Total solar eclipses occur on a regular and predictable basis. One that could be viewed in parts of the United States occurred on March 7, 1970. The saros cycle is a period of 18 years, 11 1 3 days, and solar eclipses occur according to this cycle. For the purposes of this exercise, we ignore leap years and assume that a year is exactly 365 days. Because the saros cycle is not a whole number of days, but instead is one-third of a day longer than a day, at the end of the saros cycle, Earth will have rotated one-third revolution beyond its location at the beginning of the cycle. Thus, if a solar eclipse is viewable at a certain location, the next solar eclipse will not be. How long after March 7, 1970, will a solar eclipse again be viewable from the United States?
Answer:
Step-by-step explanation:
The previous solar eclipse occured on March 7 , 1970 .
saros cycle has duration of 18 years , 11 + 1/3 days
So the earth goes 1 / 3 of its daily rotation beyond its previous location in the next solar eclipse on the earth . In order that we get solar eclipse on the same point on the earth , we shall have to wait for third solar eclipse
So total period of wait = 18 x 3 years + 11 x 3 + 1 = 54 years and 34 days
Date of next solar eclipse on the same spot = 1970 + 54 = 2024
7 th March + 34 days = April 10
likely date = April 10 , 2024 .

If you deposit $600 into an account which earns 4% yearly interest compounded quarterly,
how much will be in the account after 7 years, assuming you never withdraw money from
the account? Round your answer to the nearest cent if necessary and do not include the
dollar sign.
Provide your answer below:
Answer:
4,368
Step-by-step explanation:
take 600 and add 4% to get 624
then take the 624 and multiply by 7
and the answer is 4,368
let's see what to do buddy...
_________________________________
_________________________________
Step (1)
We have 600 $ .
One year later ;
[tex]600 + (600) \times \frac{4}{100} = 600 + 24 = 624 \\ [/tex]
Now we have 624 $.
_________________________________
Step (2)
One year later :
[tex]624 + (624) \times \frac{4}{100} = 624 + 24.96 = \\ 624 + 25 = 649 [/tex]
After two years we have 649 $.
_________________________________
Step (3)
One year later :
[tex]649 + (649) \times \frac{4}{100} = 649 + 25.96 \\ 649 + 26 = 675 [/tex]
After three years we have 675 $.
_________________________________
Step (4)
One year later :
[tex]675 + (675) \times \frac{4}{100} = 675 + 27 = 702 \\ [/tex]
So after four years we have 702 $.
_________________________________
Step (5)
One year later :
[tex]702 + (702) \times \frac{4}{100} = 702 + 28.08 \\ 702 + 28 = 730 [/tex]
After five years we have 730 $.
_________________________________
Step (6)
One year later :
[tex]730 + (730) \times \frac{4}{100} = 730 + 29.20 \\ 730 + 29 = 759 [/tex]
So After six years we have 759 $.
_________________________________
Step (7)
One year later :
[tex]759 + (759) \times \frac{4}{100} = 759 + 30.36 \\ 759 + 30 = 789 [/tex]
So after seven years we have 789 $.
_________________________________
There's no any more steps.
And we're done.
Thanks for watching buddy good luck.
