Answer: 20

Step-by-step explanation:

From the question, there are ten kids in a class and when any two meet, each kid says “hi” to the other kid and the answer “hi” follows.

The number hi one would hear before the class starts would be 10 multiplied by 2 because there are 10kids and 2 hi whenever the kids greet.

= 10 × 2

= 20hi

There will be 20 times the word hi would be heard

Answer:

90 times

Step-by-step explanation:

im sorry but i cant see the orange cuboid number at the bottom but i'll consider its a 5cm (i hope its correct)

firstly, you have to find the area of EACH faces then just add them togeher

whereas, diagram A

9 x 9 = 81 ( 1 face)

* since cube has 6 faces then just multiply by 6 then

answer: 486 cm²

for diagram B

front and back faces: 2(5x7)

left and right faces: 2(15x7)

top and bottom: 2(5x15)

answer: 430cm²

then compare between 486 and 430

answer should be 486 > 430

hope this helps :)

Answer: 3

Step-by-step explanation: if you had the histogram..... the first is 14 and the second is 14 too, but the first one you divide by 4 because there are only 4 lines, so that gives you 3.5

The second one you divide by 5

So, 14 divided by 5 is

2.8

If you round both of these you should have around 3

Therefore, the answer is 3

Answer:

c. 133 acres

Step-by-step explanation:

Given: coordinates of the corners of a parcel are (-8, 10), (6, 17) and (2, -4)

To find: area of the parcel

Solution:

Using heron's formula,

area of triangle joining coordinates [tex](x_1,y_1),(x_2,y_2),(x_3,y_3)[/tex] is equal to [tex]\frac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|[/tex]

Let [tex](x_1,y_1)=(-8,10)\,,\,(x_2,y_2)=(6,17)\,,\,(x_3,y_3)=(2,-4)[/tex]

Area of triangle (parcel) [tex]=\frac{1}{2}|-8(17+4)+6(-4-10)+2(10-17)|\\[/tex] [tex]=\frac{1}{2}|-8(21)+6(-14)+2(-7)|\\ =\frac{1}{2}|-168-84-14|\\ =\frac{1}{2}|-266|\\ =133\,\,acres[/tex]

Step-by-step explanation:

Step 1:  Answer the question

This algebraic expression is not a polynomial therefore, none of these options match except D.  The reason why it is not a polynomial is because there is a 7^x which is not a polynomial expression.  The expression needs to be expressed as a 7x^2 + 2x + 1.  Therefore, the answer is D.

Answer:  D, none

Answer:

They claim that 90% of the times, the orders arrive in time.

Then, out of N orders, (90%/100%)*N of them will arrive in time.

Here we have that N = 20

then the number that arrives in time is:

(90%/100%)*20 = 18

Now, experimetally we see that 4 times her packages arrived after noon (so 16 times the packages arrived in time), so we can calculate the experimental percentage as:

(X/100%)*20 = 16

X = (16/20)*100% = 80%

so the percentages doesn't match, so it the claim is not really accurate, but this is a small sample, so if the number of times that she uses the delivery increases, we may see that the experimental percentage gets closer to the claimed percentage.

Answer:

83

Step-by-step explanation:

You are trying to find the score that gives you a specific mean.  A mean is calculated by dividing the sum of the data by the amount of data.  Set up in this order, with x as the fourth score, to find the answer.

[tex]\frac{71+80+86+x}{4}=80\\\frac{237+x}{4} =80\\237+x=320\\x=83[/tex]

The fourth test score must be an 83.

Answer:

83

Step-by-step explanation:

Equation: 71 + 80 + 86 + x / 4 = 80

Add 71, 80, and 86 together.

237 + x = 80

Multiply 4 to both sides (cross multiplying).

237 + x = 320

Subtract 237 from both sides.

x = 83

Answer:

You have to define when the power should be pushed up using the 'For' statement and let an impulse be sent to the CPU to increase power by 15%

Step-by-step explanation:

We use certain functions in writing computer programs.

For the 'For' statement ; we can define conditions. First Elana would define at what point does she want the player power to get the best power.

For example if she defines that when the player has played for 2hours return an integer 1 for instance.

This value returned will now send a pulse to the CPU to increase its power to 15%.

If the player plays for further 1hour she can define the count to be 10 and so send another pulse to the CPU to increase the processing power by additional 15%

Answer:

50

Step-by-step explanation:

The solution of number is, 200.

We have to given that;

To find a number which is 30% of  number is 60.

Let us assume that,

A number is, x

Hence, We can formulate;

⇒ 60 = 30% of x

⇒ 60 = 30/100 × x

⇒ 60 = 3x / 10

⇒ 600 = 3x

⇒ 3x = 600

⇒ x = 200

Thus, The solution of number is, 600

Step-by-step explanation:

Given that the number of purses a vendor sells daily has the probability distribution represented in the table.

Expected Value, [tex]E(x)=\sum_{i=1}^{n}x\cdot p(x)[/tex]

Therefore:

[tex]E(x)=(0X0.35)+(1X0.15)+(2X0.2)+(3X0.2)+(4X0.03)+(5X0.07)\\=0+0.15+0.4+0.6+0.12+0.35\\E(x)=1.62[/tex]

If each purse sells for $50.00, the number of expected daily total dollar amount taken in by the vendor from the sale of purses

To change from a decimal to a fraction  count the number of decimals and add that many zeros after the 1 in the denominator, then simplify

To change a decimal to a percent, move the decimal to places to the right and add a percent sign

To change a fraction to a decimal divide the numerator by the denominator

To change a percent to a decimal move the decimal 2 places to the left and remove the percent sign( if there are fractions, change to a decimal)

Mass of each can = 680 grams

Step-by-step explanation:

Mass of a canvas shopping bag  = 600 grams Or [tex]\frac{600}{1000}[/tex] Kilograms

                                                      = 0.6 Kilograms

Let the mass of each can = w Kilograms

Then the mass of 5 cans = 5w Kilograms

Total mass of the bag when these cans were kept in the bag = 4 Kilograms

(5w + 0.6) = 4

5w + 0.6 - 0.6 = 4 - 0.6

5w = 3.4

w = [tex]\frac{3.4}{5}[/tex]

   = 0.68 Kilograms

   = [tex]0.68\times 1000[/tex]

   = 680 grams

Therefore, mass of each can = 680 grams

Answer:  (-6,7)

Step-by-step explanation:

Tow points, (x1, y1) and (x2, y2) are simetric in a quadratic graph when:

f(x1) = y1 = f(x2) = y2

so y1 = y2

Then if we have the point (2,7) we want to find other point that has the same value for y, this is (-6, 7)

So the correct option is  (-6,7)

Answer:

first you divide the larger number into its separate parts. Here, 23 becomes 20 and 3.

Next, you multiply each separate part — 20 x 7 and 3 x 7.

Finally, you add all the products together. 140 + 21 equals 161, the product of 23 x 7.
