The average cost of tuition plus room and board for a small private liberal arts college is reported to be $9,200 per term, but a financial administrator believes that the average cost is higher. A study conducted using 350 small liberal arts colleges showed that the average cost per term is $9,515. The population standard deviation is $1,200. Let α = 0.05. Based on the computed test statistic or p-value, what is our decision about the average cost?
1. Equal to $9,200
2. Greater than $9,200
3. Less than $9,200
4. Not equal to $9,200

Answer:

A) 112 3/4 inches

       ___  

B) 5.555 inches

Step-by-step explanation:

Each tile has its own constant width of 2 3/4 in. and length of 5 1/2 in.

The width of the sidewalk is 9 tiles wide; therefore, the width in inches can be found by calculating 9 x 2 3/4

The length of the sidewalk is 25 tiles long; therefore, the width in inches can be found by calculating 25 x 5 1/2

Sidewalk:  W = 24 3/4 in.  L = 137 1/2 in.

A) L-W

B) L/W

10^6 is a million.

7.085 a million times is what we are looking for.

So our answer is 7.085 million = 7,085,000

Answer:

50

Step-by-step explanation:

Volume of rectangular pyramid=(l*w*h)/3, so 150/3=50

Answer:

V=1/3 * L *W *H

V= 1/3 *5* 3 *10

V=1/3 *150

V= 50 m2

Answer:

im going to be honest i havent done this since las year and so i dont remember the value of that line outside but i think its 70*

Step-by-step explanation:

reason is because the c is originally 180* but it has more of and angle so the angles obv increases and you can get the angle by multiplying 70*times 7x and divide by 3

i say 3 because of the amount of angles in a triangle and the line outside if i remember correctly is the "angles" of a triangle  and that would be your answer

1) Quotient of 43.5÷3 :-

→ 14.5

2) Quotient of 24.6÷5 :-

→ 4.92

Answer:

2

Step-by-step explanation:

We know 10 1/2 is basically 10.5 or 21/2

To find the max amount of scarves she can make, simply divide the number of yards she has by 4. This will get you the number of scarves she can create.

[tex]\frac{21/2}{4} = \frac{21}{2} * \frac{1}{4} = 21/8 = 2.625[/tex]

Well.. we don't want to make .625 of a scarf since that would be ridiculous, so we will round it down to 2 since we can't make 3 either.

The max amount of scarves she can make is 2.

Answer: 8

Step-by-step explanation:

A really simple way to solve these problems is to think of g(whatever number) as the y coordinate on your graph. Therefore the question is basically asking you if x is 10, what is y. If we find 10 on the x axis, we can count up the y axis until we reach the line. So, the answer is 8

Yes you found it correct as per slope intercect form y=mx+b

Here

Slope=m=1/2

Y intercect=5

Now.

for g(10)

The coordinate is (10,8)

So

g(10)=8

Answer:

3/4, 18/24, 27/36, 36/48

Step-by-step explanation:

9 and 12 can both be divided by 3 to equal 3/4

9/12 times 2 is 18/24

9/12 times 3 is 27/36

9/12 times 4 is 36/48

Answer:

1 / 180 + 1 / t = 1/84

t = 157.5 minutes

Step-by-step explanation:

3hrs = 180 minutes

1.4 hours = 84 minutes

your rate + friend's rate = rate together

1 lap in 180 min + 1 lap in t min = 1 lap in 84 min

The equation is

1 / 180 + 1 / t = 1/84

subtract 1/180 from both sides

1/t = 1/84 - 1/180

1/t = 0.006349206349

multiply both sides by t

1 = 0.006349206349t

Divide both sides by 0.006349206349

1 / 0.006349206349 = t

157.5 = t

t = 157.5 minutes

Answer:

approximately 1.13

Step-by-step explanation:

[tex](f \circ f) = f(f(3))[/tex]

Working from the inside...

[tex]f(3) = 3^{-3} =\frac{1}{3^3} = \frac{1}{27}[/tex]

Now put this result back into  f  again.

[tex]f(\frac{1}{27})=\left(\frac{1}{27}\right)^\frac{1}{27}[/tex]

Use a calculator to approximate this; the result is 1.13.

Note:  an "exact" answer is [tex]\frac{1}{\sqrt[27]{\frac{1}{27}}}[/tex].
