5. You are buying orange juice for $3.50 per container and have a gift card worth $5. The function f(x) = 3.50x-5 represents your total cost f(x) if you buy x containers of orange juice and use the gift card. How much would you pay for 4 containers of orange juice?

Answers

Answer:

$9

Step-by-step explanation:

If you do 3.5*4 then you get 14. You then use the $5 gift card so you subtract 5 from 14 and get 9

using the equation, that would be f(x) = (3.5*4)-5. Using PEMDAS, you would do the parenthesis first so it would be f(x) = 14-5 which equals 9

Solve for x by factoring

Answers

Answer:

[tex]x=3,-7[/tex]

Step-by-step explanation:

We can solve for x by using [tex]\frac{-b\pm\sqrt{b^{2} -4ac} }{2a}[/tex]

By applying this on the quadratic equation, we get:

[tex]x=\frac{-4\pm\sqrt{4^{2}+84} }{2}[/tex]

Which simplifies to:

[tex]x=\frac{-4\pm10}{2}[/tex]

You purchased concentrated cleaner that must be diluted before use. Container a is the cleaner, which is 20% solution. Container b is pure water. You are mixing together the contents of container a and container b to produce 40 gallons of 9% solution. How many gallons from each container are needed to create the 40 gallons of 9% cleaning solution?

Answers

Answer:

18 gallons from container [tex]a[/tex] and 22 gallons from the container [tex]b[/tex] to be mixed to get the required mixture.

Step-by-step explanation:

Given that the container [tex]a[/tex] has 20% concentrated cleaner

and container [tex]b[/tex] has pure water which has 0% cleaner.

Let x gallons from container a and y gallons from the container b are mixed to get a 9% concentrated solution.

So,

[tex]9\%\; \text{of}\; (x+y) = (20\% \; \text{of}\; x )+(0\% \; \text{of}\; y)\cdots(i)[/tex]

As the total amount of the final solution= 40 gallons

So, [tex]x+y=40\cdots(ii)[/tex]

Using the value of equation (ii) in equation (i), we have

9% of 40 = 20% of x

[tex]\Rightarrow 0.09\times 40=0.2 \times x[/tex]

[tex]\Rightarrow x=\frac{0.09\times 40}{0.2}[/tex]

[tex]\Rightarrow x=18[/tex] gallons.

From equation (ii),

18+y=40

[tex]\Rightarrow y=40-18=22[/tex] gallons.

Hence, 18 gallons from container [tex]a[/tex] and 22 gallons from the container [tex]b[/tex] to be mixed to get the required mixture.

What is the answer to this equation
1) 4(x + 5) = 40

Answers

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

[tex]4(x + 5) = 40[/tex]

Divide sides by 4

[tex] \frac{4}{4} \times (x + 5) = \frac{40}{4} \\ [/tex]

[tex]x + 5 = 10[/tex]

Subtract sides 5

[tex]x + 5 - 5 = 10 - 5[/tex]

[tex]x = 5[/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

CHECK :

[tex]4(5 + 5) = 40[/tex]

Thus the solution is correct.

Ina certain county weights of women are normally distributed with a mean of 138 lb and a standard deviation of 15 lb. What percentage of women in that country weigh more than 120 lb

Answers

Answer:

88.493%

Step-by-step explanation:

We solve this question using z score formula.

Z score = x - μ/σ

where

x is the raw score = 120lb

μ is the population mean = 138lb

σ is the population standard deviation = 15lb

Hence,

z = 120 - 138/15

= -1.2

Probability value from Z-Table:

P(x<120) = 0.11507

P(x>120) = 1 - P(x<120)

1 - 0.11507

= 0.88493

Converting to percentage

= 0.88493 × 100

= 88.493%

The percentage of women in that country weigh more than 120 lb is 88.493%

Gribbles are small, pale white, marine worms that bore through wood. While sometimes considered a pest since they can wreck wooden docks and piers, they are now being studied to determine whether the enzyme they secrete will allow us to turn inedible wood and plant waste into biofuel.1 A sample of 50 gribbles finds an average length of 3.1 mm with a standard deviation of 0.72. Give a best estimate for the length of gribbles, a margin of error for this estimate (with 99% confidence), and a 99% confidence interval. Round your answer for the point estimate to one decimal place, and your answers for the margin of error and the confidence interval to two decimal places. point estimate = Enter your answer; point estimate margin of error = Enter your answer; margin of error The 99% confidence interval is Enter your answer; The 99%confidence interval, value 1 to Enter your answer; The 99%confidence interval, value 2

Answers

Answer:

a) The Margin of Error = 0.26

b) The 99% Confidence Interval = ( 2.84, 3.36)

Step-by-step explanation:

a) Margin of Error

The formula for Margin of Error =

z × Standard deviation/√n

From the above question

The z score for 99% confidence interval = 2.576

Standard deviation = 0.72

n = Random number of samples = 50

Margin of Error =

2.576 × 0.72/√50

= 1.85472 /√(50)

= 0.2622970178

Approximately to 2 decimal places = 0.26

b) 99% Confidence Interval

= Mean ± Margin of Error

Mean = 3.1mm

Confidence Interval = 3.1 ± 0.26

3.1 ± 0.26

= 2.84

3.1 + 0.26

= 3.36

The 99% Confidence Interval = ( 2.84, 3.36)
