(please show your steps)

Answers

Answer:

Step-by-step explanation:

divide through by the coefficient of [tex]x^{2}[/tex]

[tex]\frac{5x^{2} }{5}[/tex] + [tex]\frac{16x}{5} + \frac{-40}{5} = \frac{8}{5}[/tex]

[tex]x^{2} +\frac{16}{5}x -8 =\frac{8}{5}[/tex]

[tex]x^{2} +\frac{16}{5} x = \frac{8}{5} +8[/tex]

[tex]x^{2} + \frac{16}{5} x =\frac{48}{5}[/tex]

Add half of the square of the coefficient of x  to both sides [tex](\frac{1}{2} X \frac{16}{5} ) ^{2}[/tex]

[tex]x^{2} + \frac{16}{5}x + (\frac{1}{2} X \frac{16}{5} )^{2} =[/tex] [tex]\frac{48}{5} +(\frac{1}{2} X \frac{16}{5} )^{2}[/tex]

[tex]x^{2} +\frac{16}{5} x +(\frac{16}{10}) ^{2} =\frac{48}{5} +\frac{64}{25}[/tex]

[tex](x +\frac{16}{10})^{2} =\frac{304}{25}[/tex]

[tex]x +\frac{16}{10} =[/tex]±[tex]\sqrt{\frac{304}{25} }[/tex]

[tex]x = -\frac{16}{10}[/tex] ± [tex]\sqrt{\frac{304}{25} }[/tex]

[tex]x=-\frac{16}{10} + \sqrt{\frac{304}{25} }[/tex] or[tex]-\frac{16}{10} - \sqrt{\frac{304}{25} }[/tex]

on a map the scale shown is 1 inch = 5 miles if a park is 75 square miles what is the area of the park on the map

Answers

Answer:

75 miles squared

Step-by-step explanation:

First we have to convert 1 inch = 5 miles to square miles as that is what we are trying to get

So, 1 inch squared = 25 miles squared

To get 75 miles squared, we multiply both sides by 3.

So 3 * 1 inch squared = 3 * 25 miles squared

Gets us 3 inch squared = 75 miles squared

A simple random sample of 36 men from a normally distributed population results in a standard deviation of 10.1 beats per minute. The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal​ range, the result is a standard deviation of 10 beats per minute. Use the sample results with a 0.10 significance level to test the claim that pulse rates of men have a standard deviation equal to 10 beats per minute.
Complete parts​ (a) through​ (c) below.
a. Identify the null and alternative hypotheses.
b. Compute the test statistic. χ2 = ___ (round to three decimals)
c. Find the​ P-value. ​P-value=____​(Round to four decimal places as​ needed.)
d. State the conclusion. (reject null/ eccept null)

Answers

Answer:

Step-by-step explanation:

Given that:

sample size n = 36

standard deviation = 10.1

level of significance ∝ = 0.10

The null hypothesis and the alternative hypothesis can be computed as follows:

[tex]H_0 : \sigma = 10[/tex]

[tex]H_1 : \sigma \neq 10[/tex]

The test statistics can be computed as follows:

[tex]X^2 = \dfrac{(n -1)s^2 }{\sigma ^2}[/tex]

[tex]X^2 = \dfrac{(36 -1)10.1^2 }{10^2}[/tex]

[tex]X^2 = \dfrac{(35)102.01 }{100}[/tex]

[tex]X^2 = \dfrac{3570.35 }{100}[/tex]

[tex]X^2 =35.704[/tex]

degree of freedom = n - 1 = 36 - 1 = 35

Since this test is two tailed .

The P -value can be determined by using the EXCEL FUNCTION ( = 2 × CHIDIST(35.7035, 35)

P - value = 2 × 0.435163515

P - value = 0.8703      ( to four decimal places)

Decision Rule : To reject the null hypothesis if  P - value is less than the 0.10

Conclusion: We fail to reject null hypothesis ( accept null hypothesis) since p-value is greater than 0.10 and we conclude that there is sufficient claim that the normal range of pulse rates of adults given as 60 to 100 beats per minute resulted to a standard deviation of 10 beats per minute.

Full question :

A man buys a certain number of oranges at 20 for Rs. 60 and an equal number at 30 for Rs. 60. He mixes them and sells them at 25 for Rs. 60. What is the gain or loss percent?

Answer:

4% loss(percentage loss on cost price)

Step-by-step explanation:

we will be employing algebra in solving this problem :

20 oranges at 60 Rs=60Rs/20 per orange=3Rs per orange

Say x oranges bought at 3Rs per orange=3Rsx

Equal number of oranges at 30 oranges for 60 Rs=60Rs/30 per orange=2Rs per orange

Say x oranges bought at 3Rs per orange=2Rsx

Total Cost Price = 3Rsx + 2Rsx = 5Rsx

He then sells all oranges at 25 for 60 Rs

Therefore price per orange=60/25=12/5Rs

since he sold x+x oranges(from the above calculations)

Total selling price=total oranges *12/5Rs=2x oranges*12/5Rs=24x/5Rs

Profit or loss=24x/5-5x=-x/5

therefore we have a loss =-x/5

Percentage of loss(on cost price)

Find the maximum rate of change of f at the given point and the direction in which it occurs. f(x, y)

Answers

Answer:

f (x,y) = sin (x,y)  & points = (1,0)

Maximum  rate of change in f at given point & direction = 1

Step-by-step explanation:

The function & points are not given,

Considering them as general example : f (x,y) = sin (x,y) & points = (1,0)

Maximum rate of change in f (x,y) happens in direction of ∇ f (1,0)

∇  f (x,y) =  [ df / dx ,  df/ dy ]

= [ y cos (xy) , x cos (xy) ]

∇ f (1,0)  = [ 0, cos (0) ] = (0,1)

Magnitude at (1,0) = ∇ f (1,0)  = √ 0^2 + 1^2  = 1

-8/5 divided by 5/-6 PLS HURRY!!!

Answers

Answer: 48/25

Step-by-step explanation:

Answer:

48/25 as an improper fraction, 1 23/25 as a mixed fraction.

Step-by-step explanation:

It is -8/5 divided by 5/-6.

First of all, you can get rid of the negative signs becasue there are two.  Negative and Negative equals positive, so we already know that the answer will be positive.  

So, we now have 8/5 divided by 5/6.

When you divide fractions, the fraction being divided is turned to it's reciprocal.  To get a fraction's reciprocal, just flip the numerator and denominator's places.  It's that easy!  

Here is an example:  2/3's reciprocal is 3/2.  The numbers just get flipped!

That would mean 5/6's reciprocal would be 6/5.  Don't find the reciprocal of 8/5 because it is not the number that is getting divided.  When you find a reciprocal you can change the division sign into a multiplying sign.

Example:  2/3 divided by 4/5.  Reciprocal of 4/5 is 5/4.  Now it is 2/3 TIMES 5/4.

Back to the problem.

We now have 8/5 TIMES 6/5.  When you multiply fractions, just multiply both numerators, in this case being 8 and 6, and the denominators, in this case being 5 and 5.  So 8 times 6 is 48.  5 times 5 is 25.

We now have 48/25, which can be reduced to 1 23/25!  

For the mixed number, if you are confused, 25 goes into 48 only one time.  So, the whole number is 1.  but when 25 goes into 48 only one time, there is still 23 left because 48-25= 23.  23 is our new numerator!  The denominator stays the same.  So, it's 1 23/25.  :)

If the number 4 were added to the set { 2,3,3,3,4,5,8 }, which central tendency would change?

Answers

Answer:

The central tendency that changes is the median.

Step-by-step explanation:

- The mean without number 4 is 28.

28/7 = 4

But if we add the 4, the mean would be 32.

32/8 = 4

The mean does not change.

- The mode also does not change because the number that appears most frequently is 3.

- And the range does not change either since the range is the subtraction of the largest number with the smallest, in this case:

8 - 2 = 6

- On the other hand, the median is the middle number, without 4 the median would be 3, but with 4 the median would be 4 + 4/2, which is the same 4.

2(4x-6) = 4(3x-7) what is x​

Answers

Answer:

The value of x in this equation is -4.

Step-by-step explanation:

2(4x - 6) = 4(3x - 7)

Distribute 2 to (4x - 6) and distribute 4 to (3x - 7)

8x - 12 = 12x - 28

Subtract 12x form both sides of the equation.

-4x - 12 = -28

Add 12 to both sides of equation.

-4x = 16

Divide -4 on both sides of the equation.

x = -4

The value of x is -4.

Answer:

x=4

Step-by-step explanation:

Starting with 2(4x-6) you apply the distributive law: a(b-c) = ab - ac

a =2,  b=4x, c=6

2(4x-6) = 2*4x-2*6 Then multiply the numbers 2*4

8x-2*6 = multiply 2*6

8x-12

Then for 4(3x-7) you apply the distributive law.

a =4, b=3x, c=7

4*3x-4*7 multiply 4*3

12x-4*7 multiply 4*7

12x-28

Then the equation would be 8x-12 = 12x-28. Add 12 to both sides.

8x=12x-16 Subtract 12x to both sides

-4x=-16 divide both sides by -4

then you'll get Positive 4 as your x.
