Answer:

 =34 minutes.

Step-by-step explanation:

Done according to my own understanding!

15mg - 7.25mg = 7.75mg

   7.75mg / 20min = 0.3875mg per minute

       7.25mg - 2mg = 5.25mg

             5.25mg / 0.3875mg = 13.5483871 minutes

                     13.5483871 minutes + 20 minutes = 33.5483871 minutes

                                  =34 minutes.

Must be part of a specific member group to join . - CREDIT UNION.

Credit Unions require that you are a member of a member group to join as well as other entry requirements unlike a bank where the qualification rules are less stringent.

Profits are given to shareholders . - BANK.

A Bank is owned by its investors and shareholders so they will have to distribute profits to them unlike a Credit Union that is owned by its members.

Offer checking and savings accounts, CDs, loans . BOTH.

Both Credit Unions offer these financial products and accounts.

Deposits are insured up to $250,000  - BOTH.

Both of these types of Institutions are insured up to $250,000 by the United States Governments. Credit Unions are insured by the National Credit Union Share Insurance Fund (NCUSIF) and banks are insured by the FDIC (Federal Deposit Insurance Corporation).

Fees tend to be higher . BANKS.

Banks are for profit institutions so they will charge higher fees to make more profit for their investors.

Interest customers earn on deposits tends to be higher. - CREDIT UNIONS.

Credit Unions earn higher deposit interest for customers because they are not-for-profit so do not have to offer less rates to keep more money for their investors.

Bank, credit union, or both have been for each of the statements below:

Banks are financial institutions that have licenses to accept deposits from customers and provide loans when the conditions are met.

Credit Unions, on the other hand, are not operated for the purpose of making profits. They are formed by members who hold an agreement and their methods of operation are similar to the commercial banks.

In the given points above the similarities and differences between these two financial institutions are shown.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the expression 4x+2 = 8X-5. To find the value of x, we need to follow the steps;

Sep 1:

Add 5 to both using addition property to move 5 to both sides

4x+2+5= 8x-5+5

4x+7 = 8x

Step 2:

Collect like terms

4x-8x = -7

-4x = -7

Step3:

Divide both sides by -4

-4x-4 = -7/-4

x = 7/4

Answer:

(4,5)

Step-by-step explanation:

Answer:

y = -8x + 54

Step-by-step explanation:

Since the lines are parallel, their slopes are the same, leaving you with y = -8x.

That equation at x = 7 would make y -56, but we want it to be -2. Therefore we add a 54 in the end, leaving you with y = -8x + 54.

Answer:  (7) 7.0              (8) 17.3            (9) 64.7°

Step-by-step explanation:

Law of Cosines is: a² = b² + c² - 2bc · cos A

                         or: b² = a² + c² - 2ac · cos B

                         or: c² = a² + b² - 2ab · cos C

7) b = 4, c = 10, ∠A = 34

a² = b² + c² - 2bc · cos A

   = 4² + 10² - 2(4)(10) · cos 34°

   = 16 + 100 - 80 (0.829)

   = 116 - 66.323

   = 49.677

a = [tex]\sqrt{49.677}[/tex]

a = 7.0

8) a = 11, b = 8, ∠C = 131

c² = a² + b² - 2ab · cos C

   = 11² + 8² - 2(11)(8) · cos 131°

   = 121 + 64 - 176 (-0.656)

   = 185 + 115

   = 300

c = [tex]\sqrt{300}[/tex]

c = 17.3

9) a = 10.5, b = 5.9, c = 9.6

9.6² = 10.5² + 5.9² - 2(10.5)(5.9) · cos C

92.16 = 110.25 + 34.81 - 2(10.5)(5.9) · cos C

92.16 = 145.06 - 123.9 cos C

-52.9 = -123.9 cos C

0.427 = cos C

cos⁻¹ (0.427) = C

Answer:

1/18

Step-by-step explanation:

We are considering that we have 2 dices with 6 faces each (so, the probability to getting any face in any dish is 1/6). To get an 11, we only have two ways to obtain it:

Dice 1= 6 and Dice 2 =5 or Dice 1= 5 and Dice 2 =6

So, the probability of the event is given as:

P(Dice1=5 ∧ Dice2=6) ∪ P(Dice1=6 ∧ Dice2=5) = P(Dice1=5) x P(Dice2=6) + P(Dice1=6) x P(Dice2=5) = 1/6 x 1/6 + 1/6 x 1/6 = 1/36 + 1/36 = 2/36 = 1/18.

As 1/18 = 0,055, and 0,055 > 0,05, we consider the event as not significative (according to the definition of significance in the sentence).

Answer:

[tex]-2\frac{7}{20}[/tex]

Step-by-step explanation:

Given the following question:

[tex]3\frac{2}{5} -5\frac{3}{4}[/tex]

To find the answer we first need to convert the mixed numbers into improper fractions, find the common denominator, subtract the denominators, and of course convert the improper fraction back into a mixed number.

[tex]3\frac{2}{5} -5\frac{3}{4}[/tex]
[tex]3\frac{2}{5}=5\times3=15+2=17=\frac{17}{5}[/tex]
[tex]5\frac{3}{4} =4\times5=20+3=23=\frac{23}{4}[/tex]
[tex]\frac{17}{5} -\frac{23}{4}[/tex]

Find the common denominator:
[tex]CD=20[/tex]
[tex]\frac{17}{5} \times4=\frac{68}{20}[/tex]
[tex]\frac{23}{4} \times5=\frac{115}{20}[/tex]
[tex]\frac{68}{20} -\frac{115}{20}[/tex]
[tex]68-115=-47=-\frac{47}{20}[/tex]
[tex]=-\frac{47}{20}[/tex]

Convert the improper fraction into a mixed number:
[tex]-\frac{48}{20}[/tex]
[tex]-\frac{47}{20} =47\div20=-2\frac{7}{20}[/tex]
[tex]=-2\frac{7}{20}[/tex]

Your answer is "-2 7/20."

Hope this helps.

[tex]2\frac{7}{20}[/tex] is the mixed number we get by subtracting  [tex]3\frac{2}{5}[/tex] from [tex]5\frac{3}{4}[/tex].

To subtract [tex]3\frac{2}{5}[/tex] from [tex]5\frac{3}{4}[/tex], we first need to convert both mixed numbers to improper fractions.

[tex]5\frac{3}{4}[/tex] = (4 × 5 + 3) / 4 = 23/4

[tex]3\frac{2}{5}[/tex] = (5 × 3 + 2) / 5 = 17/5

Now we can subtract the two fractions:

23/4 - 17/5

To subtract fractions, we need to have a common denominator.

The common denominator for 4 and 5 is 20.

We'll convert both fractions to have a denominator of 20:

23/4 = (23 × 5) / (4 × 5) = 115/20

17/5 = (17 × 4) / (5 × 4) = 68/20

Now we can subtract the fractions:

115/20 - 68/20

= (115 - 68) / 20

= 47/20

Step-by-step explanation:

A graph is concave down where its second derivative is negative. That will be where the slope of the first derivative is negative.

Your graph shows the first derivative has negative slope at the left and right ends. The function f(x) will be concave downward on those intervals:

  (–4, –2) U (2, 4)

Answer and explanation:

1. Cost is response variable while file size is explanatory variable. Cost is response variable here because it is the dependent variable and the other is the independently variable that affects the dependent variable cost. The scatter plot will show how much cost increase with each change in file size. Scatter plot is in positive direction and strong

2. Time of delay of thunder is response variable while distance from lightning is explanatory variable. Time of delay is dependent variable while the other is independent variable which affects it. Scatter plot shows how much delay of thunder changes with change in distance from lightning. Positive scatter plot and strong

3. Your distance from it is explanatory variable while apparent brightness is response variable. Distance from it is independently variable while the the other is dependent variable. Scatter plot shows change of brightness with each change of distance. Negative direction as distance increase results in brightness decrease. It is strong.

4. weight of car is response variable while age of owner is explanatory variable. Weight of car is dependent variable while the other is independent variable. Scatter plot shows change of weight of car with change of age of owner. Positive direction as one increases the other increases. Strong

so in this case if they were to push the tables togther only 1 can sit at one square table if there pushed together

unless each table held 2 people like one on one side and one on the other it would be the same formula because 10 on one side of the tables and 10 on the other side would be 10x2

10+10=20 or 10x2=20
