Nami is adding a mosaic pattern to the top of a small round table.the distance around the edge of the table top is 4.7 feet .wha
Alchen [17]

Given, Nami is adding a mosaic pattern to the top of a small round table.

Given, the distance around the edge of the table top is 4.7 ft.

That means the circumference given is 4.7 ft.

We know that the formula to find circumference is C = 2\pi r

Where, C = circumference, r = radius.

Here to get the area first we will find the radius of it. So we will substitute the value of circumference in the formula. We will get,

4.7 = 2\pi r

To get r, we will move 2\pi to the left side by dividing it to both sides. We will get,

\frac{4.7}{(2\pi) } = \frac{(2\pi r )}{(2\pi) }

\frac{4.7}{(2\pi) } = r

0.748 = r ( Approximately taken upto three decimal place)

So we have got the radius here. Radius is 0.748 ft. We will have to find the area now. We know that the formula to find the area is,

A = \pi r^2, where A = area, r = radius.

By substituting the value of r we will get,

A = \pi (0.748)^2

A = 1.76 (Approximately taken upto two decimal place)

So the area Nami needed = 1.76 square ft.

We have got the required answer here.

♡ The Question ♡

-  -4(-3n-8)=104

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ The Answer ♡

-  D) 6

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ The Explanation/Step-By-Step ♡

-  -4(-3n - 8) = 104

Divide both sides by -4!

-4(-3n - 8) over -4 = 104/-4

Simplify!

-3n - 8 = -26

Add 8 to both sides!

-3n - 8 + 8 = -26 + 8

Simplify!

-3n = -18

Divide both sides by -3!

-3n/-3 = -18/-3

Simplify!

n = 6

2nq=3+7nq solve for n thanks
Gnesinka [82]

Answer:

n = - \frac{3}{5q}

Step-by-step explanation:

Given

2nq = 3 + 7nq ( subtract 7nq from both sides )

- 5nq = 3 ( divide both sides by the multiplier - 5q )

n = \frac{3}{-5q} = - \frac{3}{5q}

All human blood can be "ABO-typed" as O, A, B, or AB, but the distribution of the types varies a bit among groups of people. Her
Tanya [424]

Answer:

a. Pr(They both have type O)

= Pr(They both have type O)

= 0.35 x 0.45

= 0.1575 = 15.75%

b. Pr( they both have the same blood type)

= Pr( they both have the same blood type)

= 2/8

= 0.25 = 25%

c. Pr( at least one person has type O)

= Pr (at least one person has type O)

= 1 - 0.3575

= 0.6425 = 64.25%

Step-by-step explanation:

a) Data:

                   O       A         B       AB

Chinese   0.35   0.27    0.26     0.12

American 0.45   0.4      0.11       0.04

b) Calculations:

i. Pr(They both have type O)

= Probability of Chinese with O multiplied by Probability of American with O

= 0.35 * 0.45

= 0.1575 = 15.75%

ii. Pr( they both have the same blood type)

= Probability of two out of 8 outcomes

= 2/8

= 0.25 = 25%

iii. Pr( at least one person has type O)

= Probability of (1 – p(none) )

The probability of none = p(none O blood type)

= p(none)

for Chinese = (0.27 + 0.26 + 0.12) * for American ( 0.4 + 0.11 + 0.04)

= 0.65 * 0.55 = 0.3575

Pr (at least one person has type O) = 1 - 0.3575

= 0.6425
