Note that multiplication is commutative, in simpler terms, the order of multiplication doesn't matter at all. We shall use this to solve the problem.
[tex](-4)\times(-3\frac{5}{6} )= (-4)\times(-3)\times(\frac{5}{6})[/tex]
Now, what we also know is that a negative number times a negative number is a positive number. And we also know that 4 times 3 is 12.
So,
Writing the same thing in a more convenient way:
[tex]12\times\frac{5}{6} = 12\frac{5}{6}[/tex]
So the answer is the second alternative
In a recent year, 6% of cars sold had a manual transmission. A random sample of college students who owned cars revealed the following: out of 124 cars, 29 had manual transmissions. Estimate the proportion of college students who drive cars with manual transmissions with 90% confidence.
Answer:
The estimate the proportion of college students who drive cars with manual transmissions with 90% confidence is
[tex]0.171 < p < 0.297 [/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 124
The population proportion p = 0.06
The number of cars with manual transmissions is k = 29
From the question we are told the confidence level is 90% , hence the level of significance is
[tex]\alpha = (100 - 90 ) \%[/tex]
=> [tex]\alpha = 0.10[/tex]
Generally the sample proportion is mathematically represented as
[tex]\^ p = \frac{ 29 }{124 }[/tex]
=> [tex]\^ p = 0.234[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.645 [/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]
=> [tex]E = 1.645 * \sqrt{\frac{0.234 (1- 0.234 )}{124} } [/tex]
=> [tex]E = 0.063 [/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\^ p -E < p < \^ p +E[/tex]
=> [tex]0.234 - 0.063 < p < 0.234 + 0.063 [/tex]
=> [tex]0.171 < p < 0.297 [/tex]
The cost of 90 kg of rice is 4500. what is the cost of 2 quintal of rice?
Answer:
The cost of 2 quintal of rice is $10,000.
Step-by-step explanation:
To determine the cost of 2 quintals of rice, knowing that 90 kilos of said product is worth $ 4,500, it is first necessary to establish the equivalence between quintals and kilograms. In this regard, a quintal is equivalent to 100 kilograms, so 2 quintals are equivalent to 200 kilos.
Now, to determine the cost per kilogram of rice, the following calculation is required:
4,500 / 90 = X
50 = X
Therefore, 1 kilogram of rice costs $ 50. Thus, since 200 x 50 equals 10,000, 2 quintals of rice will cost $ 10,000.

Answer:
If a set of points is a function, the elements of the set must have the same number of elements.
For example, if the function is from A→B, the elements must be ordered pairs.
So Y is not a function.
---------------------------------------------------------------------------------------------
If Y is in fact {(2, 6), (3, 1), (4, 1), (5, 6)}
then Y is a function, because each of the first coordinates appears only once.
In functional notation, we have f(2)=6, f(3)=1 etc....
remark: if a first coordinate is repeated, for example if we have (2, 6) and also (2, 8)
this would mean f(2)=6, but also f(2)=8, which means f is not a function.

The enrollment at a university increased from 16,000 students to 20,000 students over a period of 5
years. What is the percent increase in enrollment?
difference
net/
Answer:
25%
Step-by-step explanation:
Initial no of students = 16,000
Final no of students = 20,000
We need to find the percent increase in enrollment.
The increase in no of students = 20,000 - 16,000
= 4000
Percentage = (increase/initial no of students) × 100
[tex]\%=\dfrac{4000}{16000}\times 100\\\\=25\%[/tex]
Hence, the percent increase is 25%.
A study of the career plans of young women and men sent questionnaires to all 722 members of the senior class in the College of Business Administration at the University of Illinois. One question asked which major within the business program the student had chosen. The researcher examined the relationship between gender (men/women) and chosen major. The SPSS p-value was 0.0027. The conclusion of the statistical test is:
Answer: statistically significant
Step-by-step explanation:
The p-value of a statistical test tell us the conclusion to our hypothesis. When the result of the p-value lies between 0.27 it means there is a 27% chance of it occurring, when it is at 0.02 it means there is a 2% chance of it occurring. When it lies between 0.0027 it means there is 0.27 chance of it occurring this becomes statistically significant as this won’t have much changes or effects on the hypothesis. So what this means is there is chance it won’t occur.

By the Exterior Angle Theorem, which of the following is a true statement?
Answer:
2nd option is the correct answer
Step-by-step explanation:
[tex]m \angle 1 > m \angle 3 \: \& \: m \angle 1 > m \angle 7 \\ [/tex]
According to the Exterior Angle Theorem, the true statement should be considered as the option b.
What is an Exterior Angle Theorem?The exterior angle theorem defined that at the time when a triangle's side should be extended, the resultant exterior angle formed should be equivalent to the sum of the measures of the two opposite interior angles of the triangle.
So based on this, we can say that the option b is correct.

Which of the following statements best describes the location of −(−1) on a number line?
Answer:
1 unit to the right of 0
Step-by-step explanation:
Well if you distribute the - into the (-1) than you should get a positive becuase -1*-1 is positive 1. So it would be right next to 0 to the right.

If it is $5.25 for 1 pound of bananas what is the cost of 3.5 pounds
A) $18.37
B)$18.38
C)$19
D)$10.50
Hurry pls
Answer:
18.38 B
Step-by-step explanation:
let x be the cost of 3.5 pounds
5.25/1 = x/3.5
5.25=x/3.5
18.375=x
since you can't buy 3.5 pounds with 18.37 (1 penny short), you need 18.28
what's the constant of proportionality of 1.08p=t
Answer:
1.08 is the constant of proportionality.
Step-by-step explanation:
The constant value (often written k) relating amounts that rise or fall uniformly together.
It is the ratio of the amounts y and x:
k = y/x
Put another way: y = kx
Example: you are paid $20 an hour
The constant of proportionality is 20 because: Pay = 20 × Hours worked
