b) what is the probability that she starts with a black shirt.

Answer:

Step-by-step explanation:

ok, so this is an infinitly repeating function, so you can write it as:

sqrt(12-x)

Although, x is also equal to sqrt(12-x), so

x = sqrt(12-x), and

x^2 = 12-x

x^2-12+x = 0

now just apply the quadratic formula and you're good

hope i helped :D

The quadrilateral ABCD is an isosceles trapezoid, and the length of AC for the quadrilateral is 19 feet

The quadrilateral ABCD is an isosceles trapezoid

This means that:

From the above highlights, we have:

AC = 7ft + 12ft

Evaluate the sum

AC = 19 ft

Hence, the length of AC for the quadrilateral is 19 feet

Step-by-step explanation:

Since this is a subtraction problem remember to 'add the opposite' So change to addition between the two sets of parenthesis and change all the signs/operations in the second term.

Then combine like terms. This means the terms can only be added or subtracted if the have exactly the same variables and exponents. See image.

Answer:

7x+12y ≤ 600

7x+12y = 600

Step-by-step explanation:

Lets first call cars x and minivans y. Since they want to raise 600, you can do the sign ≤ and 600

≤ 600

Since it is $7 per car, we can do 7x.

Since it is $12 per minivan, we can do 12y.

Together, they have to add up to 600 or more.

7x+12y ≤ 600

If you provide some options, I might be able to give a better answer. Without options, I can't tell if they want an exact answer or not. So technically, the answer could also be:

7x+12y = 600

Answer:

a) x = 1/12

b) x = 3/4

c) x = 2/35

d) x = 20

e) x = 3/10

Step-by-step explanation:

a) 8x = 2/3

   8x/8 = (2/3) / 8

   x = 2/3 * 1/8

   x = 2/24

   x = 1/12

b) 1 1/2 = 2x

    3/2 = 2x

    (3/2) / 2 = 2x/2

    3/2 * 1/2 = x

    3/4 = x

    x = 3/4

c) 5x = 2/7

   5x/5 = (2/7) / 5

   x = 2/7 * 1/5

   x = 2/35

d) 1/4x = 5

   1/4x * 4 = 5 * 4

   x = 20

e) 1/5 = 2/3x

   1/5 * 3/2 = 2/3x * 3/2

   3/10 = x

   x = 3/10

Using a system of equations, it is found that:

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

You buy 4 health bars and 3 health drinks for $10, hence:

4x + 3y = 10.

Your friend buys 6 health bars and 2 health drinks for $10, hence:

6x + 2y = 10

2y = 10 - 6x

y = 5 - 3x.

Replacing on the first equation:

4x + 3y = 10

4x + 3(5 - 3x) = 10

-5x = -5

5x = 5

x = 1

Then:

y = 5 - 3x = 5 - 3 = 2.

Answer:

Yes, but you have to write what the slope and y-intercept of the equation is as well.

Step-by-step explanation:

(Not sure if you wanted the full answer or just if you should graph it but I'm putting it here anyways :^P)

First convert the equation from standard form to slope-intercept form.

5x-3y=18 -> 5x-18-3y -> 5/3x-6=y

5/3x is the slope and 6 is the y-intercept!

Then graph the equation.

First rewrite the equation in slope intercept form

slope intercept form: y = mx + b [ where m is slope and b is y-intercept ]

[tex]\sf \rightarrow 5x - 3y = 18[/tex]

[tex]\sf \rightarrow - 3y = 18-5x[/tex]

[tex]\sf \rightarrow y = \dfrac{-5x+18}{-3}[/tex]

[tex]\sf \rightarrow y = \dfrac{-5x}{-3} + \dfrac{18}{-3}[/tex]

[tex]\sf \rightarrow y = \dfrac{5}{3}x -6[/tex]

comparing with y = mx + b, Here we can identify that the

x-intercept:          ( then y will be 0 )

[tex]\sf \hookrightarrow \dfrac{5}{3}x -6=0[/tex]

[tex]\sf \hookrightarrow \dfrac{5}{3}x=6[/tex]

[tex]\sf \hookrightarrow x=\dfrac{18}{5}[/tex]

[tex]\sf \hookrightarrow x = 3.6[/tex]

Using it's concept, it is found that there is a 0.45 = 45% experimental probability of the coin landing on tails.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

For an experimental probability, these number of outcomes are taken from previous trials.

In this problem, 9 out of 20 trials resulted in tails, hence the experimental probability is given by:

p = 9/20 = 0.45 = 45%.

Overtime Hours Worked A random sample of 15 registered nurses in a large hospital showed that they worked on average 44. 2 hours per week. we can estimate with 90% confidence that the population mean of overtime hours worked by registered nurses in the hospital is between 42.5 and 45.9 hours per week.

The t-distribution is a probability distribution that is used to estimate the population mean of a normally distributed variable when the sample size is small or the population standard deviation is unknown.

To estimate the population mean with a 90% confidence interval, we can use a t-distribution with n-1 degrees of freedom, where n is the sample size.

First, we need to calculate the standard error of the mean, which measures the variability of sample means around the population mean. The formula for the standard error of the mean is:

SE = s / sqrt(n)

where s is the sample standard deviation and n is the sample size.

In this case, s = 2.6 and n = 15, so:

SE = 2.6 / sqrt(15) = 0.671

Next, we need to find the critical value of the t-distribution with 14 degrees of freedom and a 90% confidence level.

We can look this up in a t-table or use a calculator to find that the critical value is approximately 1.761.

Finally, we can calculate the confidence interval using the formula:

CI = X ± tα/2 * SE

where X is the sample mean, tα/2 is the critical value of the t-distribution, and SE is the standard error of the mean.

In this case, X = 44.2 and tα/2 = 1.761, so:

CI = 44.2 ± 1.761 * 0.671

CI = (42.5, 45.9)

Therefore, we can estimate with 90% confidence that the population mean of overtime hours worked by registered nurses in the hospital is between 42.5 and 45.9 hours per week.
