Answer:

64 books

Step-by-step explanation:

The first step is to find the number of books that will fit in the shelve per foot

= 40/5

= 8

Therefore the number of books that will fit perfectly in 8-foot shelf can be calculated as follows

= 8×8

= 64

Hence 64 books would fit in 8-foot shelf

Step-by-step explanation:

A = [tex]\frac{\pi r^2}{2}[/tex] or [tex]\frac{3.14r^2}{2}[/tex]

r = 4

3.14 x 4^2 = 50.24

50.24/2 = 25.12

Answer: 11

Step-by-step explanation:

Based on the information that have been given in the question, we can use the information to form an inequality which goes thus:

5 + 9.95h < 125

9.95h < 125 - 5

9.95h < 120

h < 120/9.95

h < 12.06

h < 12

Therefore since h is less than 12, the greatest number of hat that can be ordered will be 11.

Answer:

A sampling distribution of the sample proportion with n = 20 and p = 0.8

Step-by-step explanation:

We are given that

The probability of tails of a weighted coin, p=0.8

n=20

We have to find the type of distribution is simulated if this procedure repeated 75 times .

Random variable is a proportion of number of tails therefore, type of distribution is   sampling distribution of the sample proportion.

We have n=20 and p=0.8

Hence, we can say that type of distribution is simulated is given by

A sampling distribution of the sample proportion with n = 20 and p = 0.8

Answer:

I chose answer D. A binomial distribution with n=20 and p=0.8, No clue if correct or not

Answer:

BOTH ARE CORRECT

Step-by-step explanation:

Given that:

Triangle ABC Is right angled ;Angle ABC

Hypotenus = 15

If legs are 9 and 12 units long ;

From Pythagoras :

9² + 12² = hypotenus²

81 + 144 = 225²

2.) if:

B = 20° ; BC = will be

Using :

Cos θ = BC / 15

Cos 20 = BC / 15

BC = Cos 20 * 15

BC = 0.939692 * 15

BC = 14.09

BC = 14.1

Answer:

only 1 and 2 are correct

Step-by-step explanation:

Here, we want to select appropriately

From the question, all we had to do is to make a subtraction; and that is;

3 5/12 -2 2/3

1. 2 8/12 can be reduced to 2 2/3; so the answer here is yes

2. 3 15/36 can be reduced to 3 5/12

and 2 24/36 can also be reduced to 2 2/3; so this is correct also

3. This is wrong

4. This is wrong

Answer:

Please check the explanation.

Step-by-step explanation:

Given

P(Z > 1.96)

To determine

What probability expression is equivalent to P(Z > 1.96)

Suppose Z is a standard normal variable.

Therefore,

P(Z > 1.96) = 1 - P(Z ≤ 1.96)

solving

                 = 1 - Ф(1.96)

                 = 1 - 0.9750

                 = 0.0250

The probability of the expression being equivalent to P(z > 1.96) is calculated as 0.0250.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

The given information is P(z > 1.96)

Let z is a standard normal variable. Then we have

P(z > 1.96) = 1 – P(z ≤ 1.96)

P(z > 1.96) = 1 – 0.9750

P(z > 1.96) = 0.0250

Answer:

BC = 4 cm

BE = 10.39

Step-by-step explanation:

ABCD is an isosceles trapezoid.

Measures of base angles of an isosceles trapezoid are equal.

[tex]\therefore m\angle ABC = m\angle DCB [/tex]

[tex]\because m\angle DCB = 120\degree [/tex]

[tex]\therefore m\angle ABC = 120\degree [/tex]

[tex] m\angle ABE = 120\degree-90\degree [/tex]

[tex] m\angle ABE = 30\degree [/tex]

in triangle ABE,

[tex]\cos 30\degree =\frac{BE}{12}[/tex]

[tex]\frac{\sqrt 3}{2} =\frac{BE}{12}[/tex]

[tex] BE = \frac{\sqrt 3\times 12}{2} [/tex]

[tex] BE =6\sqrt 3\: cm[/tex]

[tex] BE = 10.39 cm[/tex]

[tex]\sin 30\degree =\frac{AE}{12}[/tex]

[tex]\frac{1}{2} =\frac{AE}{12}[/tex]

[tex] AE = \frac{12}{2} [/tex]

[tex] AE =6 \: cm[/tex]

Next, Draw [tex] CF\perp AD [/tex]

FD = AE = 6

EF = 16 - (AE + FD) = 16 - (6+6) = 16-12

EF = 4 cm

BCFE is a rectangle.

Measures of the opposite sides of a rectangle are equal.

Therefore

BC = EF

BC = 4 cm

Answer:

Hey, I'm not sure if my assumptions were correct or not because there is no diagram. I assumed the triangle to be equilateral, the two lines are parallel and the height of the triangle is 1.

Step-by-step explanation:

Since the triangle is parallel*, we can just use ratio and proportion.

[tex] \frac{rise}{run} = \frac{1}{34 - x} = \frac{0.5}{9x - 59} \\ \frac{1}{34 - x} = \frac{0.5}{9x - 59} \\ 1(9x - 59) = 0.5(34 - x) \\ 9x - 59 = 17 - .5x \\ 9x + 0.5x = 59 + 17 \\ 9.5x = 76 \\ x = \frac{76}{9.5} \\ x = 8[/tex]

Now that we had found the value of x, we will now substitute that to both equations to get the respective distances.

CE = 34 - x = 34 - 8 = 26

Since y varies inversely as x,  then xy = k  

                                                          2(8) = 16 = k

Therefore, xy = 16

Answer:

3.5%

Step-by-step explanation:

Given data

A=$6225

P=$5000

T= 7years

R=???

Simple interest

A=P(1+rt)

substitute

6225=5000(1+7r)

6225=5000+35000r

collect like terms

6225-5000=35000r

1225=35000r

r= 1225/35000

r=0.035

Hence the rate is 0.035*100= 3.5%

x + 6.8 = 8.9

Step-by-step explanation:

First let's break this sentence down into parts.

A number increased by 6.8 is 8.9.

"A number" - This value is unknown, therefore we will represent it with x.

"increased by" - This signifies that we will be adding.

"is" - This represents the equal sign (=)

Now let's put these together.

x + 6.8 = 8.9

This is your expression.
