If th ere are 10,000 stu dents enrolled in the college an d the institution is funded at the rate of $300 per student unit. At the 95 % confidence level, estimate the interval th at covers the total funding of the college . for full credit, round the answer to TWO decimal places!

Answer: (35823600 , 36176400)

Step-by-step explanation:

Mean number of units = 12

Standard deviation = 3

Number of samples (n) = 10000

Fund rate = 300

Mean = 10000 * 300 * 12 = 36000000

Standard deviation = 10000^0.5 * 300 * 3 = 90000

Fir 95% C. I

Z0.05 = 1.96

Interval = mean ± 1.96 * SE

(36000000 - 1.96*90000) ; (36000000 + 1.96*90000)

(35823600 , 36176400)

Help I really really need it.

Answers

Answer:

$400.00

Step-by-step explanation: The shirt was bought at 20% of its original value, or 1/5th. To calculate it's original value, we multiply it by it's inverse 5/1, which is 5 times it's sale price. 80 * 5 = 400.

what is 24 divided by 8/15

Answers

Answer:

45

Step-by-step explanation:

put 24 over 1 to make it a fraction.

So now its:

24/1 divided by 8/15

Now cross multiply

So now its:

24*15/1*8

(24 times 15)

Over

(1 times 8)

=360/8

=45

24 divided by 8/15 is equal to 45.

To divide 24 by 8/15, we can simplify the problem by multiplying 24 by the reciprocal of 8/15, which is 15/8. Multiplying fractions involves multiplying the numerators and denominators.

So, 24 divided by 8/15 can be rewritten as 24 multiplied by 15/8:

24 * (15/8)

When we multiply the numerators (24 * 15) and the denominators (1 * 8), we get:

360/8

Simplifying the fraction by dividing both the numerator and denominator by their greatest common factor, which is 8:

45/1

Therefore, 24 divided by 8/15 is equal to 45.

Ab and c lie on a straight line BD=CD BCD=15 BAD=5 Work out x

Answers

Answer:

[tex]x = 10[/tex]

Step-by-step explanation:

The attachment completes the question;

From the question, we have the following given parameters

[tex]BD = CD[/tex]

[tex]\angle BCD = 15\deg[/tex]

[tex]\angle BAD = 5\deg[/tex]

Required

Solve for x

Since [tex]BD = CD[/tex] then

[tex]\angle CBD = \angle BCD[/tex] --- Property: Base angle of an isosceles triangle

[tex]\angle CBD = \angle BCD = 15[/tex]

Also, ABC is a straight line;

So:

[tex]\angle CBD + \angle DBA = 180[/tex] --- angle on a straight line

Substitute 15 for [tex]\angle CBD[/tex]

[tex]15 + \angle DBA = 180[/tex]

Make [tex]\angle DBA[/tex] the subject

[tex]\angle DBA = 180 - 15[/tex]

[tex]\angle DBA = 165[/tex]

Considering triangle DBA

[tex]\angle DBA + \angle BAD + x = 180[/tex] ---- angles in a triangle

Substitute 165 for [tex]\angle DBA[/tex] and 5 for [tex]\angle BAD[/tex]

[tex]165 + 5 + x = 180[/tex]

Make x the subject

[tex]x = 180 - 165 -5[/tex]

[tex]x = 10[/tex]

Tracy can type 45 words in 3 minutes. At that rate, how many minutes would it take Tracy to type 315 words?​

Step-by-step explanation:

The rate that she types is 15 words in a minute

315/15 =

Answer:  It will take Tracy 21 minutes to type 315 words

Step-by-step explanation:

Set up a proportional relationship to solve for the  number of minutes.

45 words  = 3 mins

315  words =  x mins.  

[tex]\frac{45}{315} = \frac{3}{x}[/tex]      Cross multiply  

45x = 945    Divide both sides by 45

 x = 21  

Juan needs to take an Uber to get to the movies. The Uber charges $1.50 for the first mile, and then $1.55 for each mile after that. If the total charge is $10.49, then how far was Juan’s Uber ride to the movie?

Answers

Answer:

5.8 miles were travelled by Juan's Uber ride to the movie.

Step-by-step explanation:

Let x = miles travelled by Juan

Charges for first mile = $1.50

Charges for each mile after first = $1.55

Total charge for Juan = $10.49

We need to find how many miles Juan covered?

The equation will be:

[tex]1.50+1.55(x)=10.49[/tex]

We will solve this equation to find value of x

Solving:

[tex]1.50+1.55(x)=10.49[/tex]

Subtracting 1.50 from both sides

[tex]1.50+1.55(x)-1.50=10.49-1.50\\1.55(x)=8.99\\x=\frac{8.99}{1.55} \\x=5.8[/tex]

So, 5.8 miles were travelled by Juan's Uber ride to the movie.

The volume of a cylinder is 4πx3 cubic units and its height is x units. Which expression represents the radius of the cylinder, in units? 2x 4x 2πx2 4πx2

Answers

Answer:

It's A

Step-by-step explanation:

The expression that represents the radius of the cylinder is 2x

What is volume?

The volume of a shape (e.g. cylinder) is the amount of space in the shape i.e. the cylinder

Below, is how to calculate the radius of the cylinder

The volume is given as:

V = 4πx³

The volume of a cylinder is:

V = πr²x

By comparison, we have:

πr²x = 4πx³

Divide the common factors

r² = 4x²

Take the square root of both sides

r = 2x

Hence, the expression that represents the radius of the cylinder is 2x
