Answer:

82%

Step-by-step explanation:

The total number of marbles is 9 + 6 + 7 + 11 = 33.  6 marbles are blue, so 27 are not.  So the probability of selecting a non-blue marble is 27/33 ≈ 82%.

The probability of NOT getting a blue marble is 82%.

Probability denotes the possibility of the outcome of any random event.

Given that, a bag contains 9 red marbles, 6 blue marbles, 7 green marbles, and 11 yellow marbles, one is selected randomly, we need to find the probability that a blue marble will not be selected,

So, the probability of NOT event = 1-P(E)

Therefore,

The probability of getting a blue marble = 6/33 = 2/11

The probability of NOT getting a blue marble = 1-2/11 = 9/11

= 0.81818181 ≈ 82%

Hence, the probability of NOT getting a blue marble is 82%.

The original price of the computer is $ 6,000  .

Step-by-step explanation:

Given as :

The selling price for the computer = $ 1,500.00

The discount coupon = 75 %

Let the original price or market price of computer = $ x

Now,

Discount % = [tex]\dfrac{\textrm market price - \textrm selling price}{\textrm market price}[/tex] × 100

Or, 75 % = [tex]\dfrac{\textrm x - \textrm 1500}{\textrm x}[/tex] × 100

Or, [tex]\frac{75}{100}[/tex] = [tex]\dfrac{\textrm x - \textrm 1500}{\textrm x}[/tex]

Answer:

The total minutes Nick volunteer in a year are 5000 minutes.

Step-by-step explanation:

Given:

Nick volunteer Saturday for 60 minutes and each Sunday for 40 minutes. He takes 2 weeks off every year.

Now, how many minutes did he volunteer in one year.

So, in one year there are 52 weeks.

And, total weeks Nick volunteer are 50 in a year as he takes 2 weeks off every year.

And, total minutes in a week nick volunteer = 60+40= 100 minutes.

Now, for getting the total minutes Nick volunteer in a year, we multiply the total weeks he volunteer in a year from total minutes he volunteer in a week :

Total minutes Nick volunteer in a year = total weeks he volunteer in a year × total minutes he volunteer in a week

Total minutes Nick volunteer in a year [tex]=50\times 100\ minutes[/tex]

Total minutes Nick volunteer in a year [tex]=5000\ minutes[/tex]

Therefore, the total minutes Nick volunteer in a year are 5000 minutes.

Answer:

m<1: 51

m<2: 61

m<3: 29

Step-by-step explanation:

m<1 = 51, because to find the 3rd angle, you need to add the other two angles and then subtract 180 from that answer.

61 + 68 = 129

180 - 129 = 51

m<2 = 61, because it's a vertical angle, meaning that the angle that's opposite to it exactly, is the same. So since the angle opposite to m<2 is 61, that's what the answer would be.

m<3 = 29, because all you need to do is add 90 and 61, and then subtract 180 by the answer. I got 90 as one of the angle measurements because there's a right triangle, meaning it's 90. Then since we already know what angle 2 is (61) then all you need to do is add:

90 + 61 = 151

Then subtract:

180 - 151 = 29

Answer:

1) Actual Measurements of Gym = 50 m x 40 m

2)The actual measurements of the closet  =20 m x 10 m

3) if 1 cm  = 12 m the actual dimensions of the gym  are : 60 m x  48 m

4) The area of the gym =  2000 sq m

Step-by-step explanation:

Here, the question is INCOMPLETE.

I am attaching the correct figure for the reference.

Here, The dimensions of Closet are   =   2 cm , 1 cm

The dimensions of gym are = 5 cm , 4 cm

Now as the scale represents 1 cm  = 10 m

So, the ACTUAL dimensions of the closet are :

2 cm  = 2 x  1 cm  = 2 x 10 m   = 20 m

1 cm  = 10 m

And, the ACTUAL dimensions of the gym  are :

5 cm  = 5 x  1 cm  = 5 x 10 m   = 50 m

4 cm  = 4 x  1 cm  = 4 x 10 m   = 40 m

Now, solving the giver parts:

1) Actual Measurements of Gym = 50 m x 40 m

2)The actual measurements of the closet  =20 m x 10 m

3) if 1 cm  = 12 m

the ACTUAL dimensions of the gym  are :

5 cm  = 5 x  1 cm  = 5 x 12 m   = 60 m

4 cm  = 4 x  1 cm  = 4 x 12 m   = 48 m

4) The area of the gym = LENGTH x WIDTH

                                        =  50 m x 40 m   = 2000 sq m.

Mean = -2

Step-by-step explanation:

Given data is:

-18, 10, -20, -11, 9, 18

Arranging the data in ascending order

-20, -18, -11, 9, 10, 18

Mean:

Mean is given by the formula

[tex]Mean=\frac{Sum}{items}[/tex]

Items are: 6

[tex]Mean = \frac{-20-18-11+9+10+18}{6}\\= \frac{-12}{2}\\= -2[/tex]

Mode:

Mode is the most frequent value in the data. So,

As there is no value repeated in the data. There is no mode

Median:

Median is the middle value of the data. As the no. of data value are even,

the average of middle 2 values is mode.

Note that the data has to be arranged in ordered to find median

Here,

[tex]Median = \frac{-11+9}{2}\\=\frac{-2}{2}\\= -1[/tex]

Range:

Range is the difference between the largest and smallest value of the data

Here

Largest value = 18

Smallest value = -20

So,

[tex]Range = Largest\ value-Smallest value\\= 18-(-20)\\= 18+20\\=38[/tex]

Answer:

$65 ≤ x ≤ $135

It can also be written as $65 ≤ x AND x ≤ $135

Step-by-step explanation:

Now, one should know the meaning of compound inequality. A compound inequality is the inequality which simply combines the two simple inequalities.

Now, in an inequality, three relations are performed, equal to, less than and greater than. You can combine 'equal to' with 'less than' or 'greater than' according to situation given.

Notice that in given sign

≤

the value at left side or the pointed side will be small or lesser than the value at right side. Also notify that if inverted, like this ≥

Value of left side will be greater. Means the value at pointed side will always be smaller. The lower bar is sign of equal to

if this is written

x ≤ 3

It means that x can be equal to three or any value less than 3 means 2,1,0,-1 etc.

Now in question given, it is stated that money should be not less than $65 means it can either be $65 or more but not less than it. Lets assume 'x' as the amount required,

So one inequality is

$65 ≤ x

For second condition which is amount should be no more than $135, means it can be $135 or less, so inequality is

x ≤ $135

Remember that we use AND in the answer because both statements of inequality are need to be fulfilled or satisfied.

Final answer:

The height of the coin when Jake tosses it is 6 feet.

Explanation:

The equation that models the height and time of the parabola is [tex]h(t) = -16t^2 + 24t + 6.[/tex]

To find the height of the coin when Jake tosses it, we need to determine the height at time t = 0.

Plugging in t = 0 into the equation, we have [tex]h(0) = -16(0)^2 + 24(0) + 6[/tex]

= 6 feet.

So the height of the coin when Jake tosses it is 6 feet.

Answer:

m∠FAD=48°

Step-by-step explanation:

The Perpendicular Bisector Theorem states that: A radius that bisect a chord is perpendicular to the chord

we have

FD=DE

The radius AC bisect the chord FE

so

AC is perpendicular to FE

The triangle FAD is a right triangle

m∠FAD+m∠AFD=90° ---> by complementary angles in a right triangle

we have

m∠AFD=42°

substitute

m∠FAD+42°=90°

m∠FAD=90°-42°

m∠FAD=48°

Answer:

Step-by-step explanation:

let the initial amount of money per person be x

let the total cost of the pizza be y

Before one person left:

10x = y ------------> (eq 1)

After one person left, each of the 9 remaining people had to pay $0.60 extra.

9(x+0.6) = y ----------(eq 2)

equating y from both equations

10x = 9(x+0.6)

10x = 9x+(0.6)(9)

10x = 9x + 5.4     (subtract 9x from both sides)

10x - 9x = 5.4

x = 5.4 (substitute this back into equation 1)

10x = y

y = 10(5.4) = $54

Final answer:

The total bill for the pizza was $54.00. Each of the ten people would have contributed $5.40, but after one person left, the remaining nine paid an additional 60 cents each.

Explanation:

When the tenth person left the group, the nine remaining people each had to pay 60 cents extra for the pizza. This means that the contribution of the tenth person would have been 9 times 60 cents, which is $5.40. To find the total bill, we also need to add the amount that the remaining nine people paid before the extra charge. Since each person originally was going to pay the same amount, this amount is also $5.40. Therefore, each of the 10 people would have paid $5.40 making the total bill 10 times $5.40, which equals $54.00.

3rd and 4th element difference = - 2 + 10 = 8

4th and 5th element difference = -10 + 18 = 8

The difference (d) is 8 and it's negative because the series is lowering the previous value.

3. Proof of d = - 8

14 - 8 = 6

6 - 8 = - 2

Answer:

16 pieces.

Step-by-step explanation:

4/1/4=16

The number of pieces of rope he cut is 16 pieces.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that;

The length of rope= 4foot

Length of each piece=0.25

Now,

To find the number of pieces of rope Kyle cut, we need to divide the length of the rope by the length of each piece:

number of pieces = length of rope / length of each piece

In this case, Kyle cut a 4 foot piece of rope into pieces that are 0.25 feet long, so we can plug these values into the formula:

number of pieces = 4 / 0.25

number of pieces = 16

Therefore, by algebra the answer will be 16 pieces.

[tex]AB=\sqrt{m^2+n^2}[/tex]

Step-by-step explanation:

Given:

In Δ ABC

m∠C= 90°

[tex]BC=m[/tex]

[tex]AC=n[/tex]

For the triangle ABC we can apply trigonometric ratio to find m∠A.

We have:

[tex]\tan\angle A=\frac{BC}{AC}[/tex]

Substituting values of side BC and AC

[tex]\tan \angle A=\frac{m}{n}[/tex]

Taking inverse tan to get m∠A.

∴ [tex]m\angle A=\tan^{-1}(\frac{m}{n})[/tex]

AB can be found out using Pythagorean theorem:

AB being the hypotenuse can be written as

[tex]AB^2=BC^2+AC^2[/tex]

Substituting values of side BC and AC

[tex]AB^2=m^2+n^2[/tex]

Taking square roots both sides:

[tex]\sqrt{AB^2}=\sqrt{m^2+n^2}[/tex]

∴ [tex]AB=\sqrt{m^2+n^2}[/tex]
