What is the solution to the equation? 3/4(4c+16)=2c+9

ella [17]

3/4(4c+16)=2c+9

We simplify the equation to the form, which is simple to understand
3/4(4c+16)=2c+9

Reorder the terms in parentheses
+(+3c+12)=2c+9

Remove unnecessary parentheses
+3c+12=+2c+9

We move all terms containing c to the left and all other terms to the right.
+3c-2c=+9-12

We simplify left and right side of the equation.
+1c=-3

We divide both sides of the equation by 1 to get c.
c=-3
Hope this helped! :)

Listed below are pulse rates (beats per minute) from samples of adult males and females. Does there appear to be a difference

MrMuchimi

Answer:

There appears to be a difference between the pulse rates from samples of adult males and females. The average pulse rate of males is 63.75 while that of females is 75.875.

Coefficient of Variation (male) = 33.44%

Coefficient of variation (female) = 28.35%

Step-by-step explanation:

Mean (male) = $\frac{sum of x}{n} =\frac{1020}{16} =63.75$

Mean (female) = $\frac{sum of y}{n} = \frac{1214}{16} = 75.875$

Standard Deviation (male) = $\sqrt{\frac{sum(x-63.75)^2}{16-1} } =21.315$

Standard Deviation (female) = $\sqrt{\frac{sum(y-75.875)^2}{16-1} } = 21.512$

Coefficient of Variation = $\frac{Std dev}{mean} *100$

For male, CV = $\frac{21.315}{63.75} *100=33.44%$ %

For female, CV = $\frac{21.512}{75.875} *100=28.35$ %

Comparison : Pulse rates of males has more variability than that of females since it has a greater coefficient of variation.

Mike has a credit rating of 720. Tyler has a credit rating of 560. Mike and Tyler apply for identical loans from Park Bank. Mike

Eva8 [605]

Answer:

6.2%

Step-by-step explanation:

Credit rating is an evaluation of the credit risk of a borrower, that how often a person is going to repay their debt, by credit rating it predicts the ability of the debtor to payback.

Mike has credit rating = 720

Tyler has credit rating = 560

Both are approved for loan. Mike's Credit score is higher, which means he is a much safer debtor as compared to Tyler. Mike will be able to pay back much easily than Tyler. Therefore Mike interest rate is 3.2%

Interest rate of Tyler is higher as he is not that trusted and has low Credit rating. Tyler is approved for a loan that charged 3 percentage points higher because of his inferior credit rating so it interest on the loan will be

Interest = 3.2%+3% = 6.2%

PLZ PLZZZZ HELP ASAP!!!!! Explain the error: 144x2 - 100 (12x + 10)(12x - 10) 2(6x + 5)(6x - 5)

iogann1982 [59]

Answer:

a factor of 2 is shown, but 4 was factored out

Step-by-step explanation:

The difference of squares is factored as ...

a² -b² = (a +b)(a -b)

Then the given difference of squares factors as ...

144x² -100 = (12x)² -10² = (12x +10)(12x -10)

Each of these factors has a factor of 2 that can be factored out:

= (2(6x +5))(2(6x -5))

= (2·2)(6x +5)(6x -5)

= 4(6x +5)(6x -5)

The first factor should be 4, not 2.
