The expected number of times to select a green pencil when the pencils are selected 1350 times is 450

The distribution of the pencils is given as:

Red = 4

Blue = 6

Green = 5

The total number of pencil is:

Total = 4 + 6 + 5

Evaluate the sum

Total = 15

The probability of selecting a green pencil is:

P(Green) = 5/15

Evaluate

P(Green) = 1/3

So, the expected number of times is:

E(x) = 1/3 * 1350

Evaluate

E(x) = 450

Hence, the expected number of times to select a green pencil is 450

The amount of cardboard needed to make a cuboid box of dimensions 8 inch, 3 inches and 3 inches is 114 sq. inches.

Let the three dimensions(height, length, width) be x, y,z units respectively.

The surface area of the cuboid is given by

[tex]S = 2(a\times b + b\times c + c\times a)[/tex]

For this case, tissue box is almost cuboid shaped.

Also, its dimensions are given being 8 inches, 3 inches and 3 inches.

Suppose we measure the amount of cardboard needed in terms of area, then, the amount of cardboard needed to make that box(without any whole, full cuboid) is equal to the area of its surface(either outer or inner if we assume 0 inches thickness of cardboard),

Thus, we get:

Amount of cardboard needed = surface area of cuboid box with dimensions 8 by 3 by 3 (in inches)

= [tex]2(8 \times 3 + 3 \times 3 + 3 \times 8) = 114 \: \rm in^2[/tex]

Thus, the amount of cardboard needed to make a cuboid box of dimensions 8 inch, 3 inches and 3 inches is 114 sq. inches.

Answer: 5

Step-by-step explanation:

Answer:

  arc BC = 26°

  arc AB = 90°

  arc CAB = 334°

Step-by-step explanation:

The angles of a linear pair total 180°. This fact lets us write an equation for x that helps us find the measures of all the angles and arcs. The arcs of a circle total 360°.

__

∠APE +∠EPD = 180°

  (25x +15)° +(33x -9)° = 180°

  58x = 174 . . . . . . divide by °, subtract 6

  x = 3 . . . . . . . . divide by 58

Angle APE is ...

  ∠APE = (25x +15)° = (25·3 +15)° = 90°

Then ...

  ∠EPD = 180° -90° = 90°

  ∠DPC = (20·3 +4)° = 64°

  ∠CPB = 90° -64° = 26°

  arc BC = ∠BPC = 26°

  arc AB = ∠APB = 180° -90° = 90°

  arc CAB = 360° -arc AB = 334°

Answer:

∠A + ∠B = 90°

Step-by-step explanation:

Complementary angles are angles which, combined, add to 90°. Therefore, an equation displaying the relationship between two complementary angles may look like this: ∠A + ∠B = 90°.

Answer:

triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. The side opposite the obtuse angle in the triangle is the longest.

Step-by-step explanation:

No; in a right triangle, the other two angles are complementary so they are both less than 90° CLASSIFYING TRIANGLES Copy the triangle and measure its angles.

Answer:

1) 14π

2) 47.1

Step-by-step explanation:

1)

Circumference = 2πr

where r = radius

given radius is 7mi

So we have C = 2πr and r = 7

==> plug in 7

C = 2π(7)

==> multiply 2 and 7

C = 14π

we leave our answer in terms of pi so this is our final answer.

2)

Again Cicumference = 2πr

The given radius here is 7.5

So C = 2πr

R = 7.5 and π = 3.14

==> plug in values

C = 2(3.14)(7.5)

==> multiply 2 and 3.14

C = 6.28(7.5)

==> multiply 6.28 and 7.5

C = 47.1

Answer:

∠POS = 128°

Step-by-step explanation:

Angles on a straight line always add up to 180°

Therefore:

∠POS + ∠POQ = 180°  (as they are the angles on line SOQ)

∠POS + 52° = 180°

∠POS = 180° - 52°

∠POS = 128°

[tex]\huge{\color{magenta}{\fbox{\textsf{\textbf{Answer}}}}}[/tex]

To find :-

The value of ∠POS

Given :-

∠POQ = 52°

Solution :-

The ∠POQ + ∠POS lies on same line SOQ. So they are linear pair and linear pair angle forms sum of 180°.

∠POS + ∠POQ = 180° {linear pair}

∠POS + 52° = 180°

∠POS = 180° - 52°

∠POS = 128°

Result :-

The angle ∠POS is 128°.

Since the sequence has a common difference of 5, hence the sequence  is 4, 9, 14, 19, ... is defined recursively using the formula  f(n 1) = f(n) – 5 .

Recursive functions are functions used to generalize sequence. Given the recursive function

f(n - 1) = f(n) – 5 .

This can be written as:

f(n) - f(n-1) = 5

This shows that the correct sequence must have a common difference of 5

For the sequence 4, 9, 14,19...

d = 9 - 4 = 14 - 9

d = 5

Since the sequence has a common difference of 5, hence the sequence  is 4, 9, 14, 19, ... is defined recursively using the formula  f(n 1) = f(n) – 5

Answer:

increase

Step-by-step explanation:

First, we need to find the mean of the given data set without any change.

10 + 61 + 10 + 44 + 21 + 79 + 27 + 12 = 264

264 ÷ 8 = 33

Now that we have the mean, we can find the mean of the data set with the change of 52.

10 + 61 + 10 + 44 + 21 + 79 + 27 + 52 = 304

304 ÷ 8 = 38

From this, we can see that the mean has increased with the change of 12 to 52. Thus, that's the correct option.

Now, required outcomes: T+2,4,6= 3/12 = 1/4

The amount that will be there in Henry's account after a period of 6 years will be $1,925.765.

Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. It's the outcome of reinvesting interest rather than paying it out so that interest is received on the principal plus previously collected interest in the next quarter.,

[tex]A = P(1+ \dfrac{r}{n})^{nt}[/tex]

The amount that Henry put in the account is $1700, while the compound interest on that account is 2.1% annually. Also, the time for which the amount is kept in the account is 72 months which is equal to 6 years.

Now, the total amount in Henry's account after a period of 6 years will be,

[tex]\rm Account\ Balance = \$1700(1+0.021)^6[/tex]

                           [tex]= \$1700(1.021)^6\\\\= \$1,925.765[/tex]

Hence, the amount that will be there in Henry's account after a period of 6 years will be $1,925.765.
