Answer:

y= 0.35

Step-by-step explanation:

y 1/4

when x=5,

find y=? when x=7.

given that y varies directly with x.

y = kx

Where k is the constant of proportionality

k= y/x

k= (1/4)÷ 5

k= 0.05

y= kx

y= (0.05)(7)

y= 0.35

The accepted values are  2 3 4 5 6   One is not counted. It says between.            

The total number of ways each dice can be thrown is  2 3 4 5 6 7 8 9 Ten is not counted. Same reason.

5/8 * 5/8 = 25/64 = 0.39

Answer:

A

E

Step-by-step explanation:

a rational number can be expressed as fraction. well, that is what the number 8/9 is.

so, A is a correct option.

as such it is automatically also a member of the real numbers (which is a superset of rational numbers). so, E is a correct option.

all other options are wrong.

8/9 is not a natural number (1, 2, 3, 4, ...).

it is not a whole number (0, 1, 2, 3, 4, ...).

it is not an integer (... , -2, -1, 0, 1, 2, 3, ...).

and as it is a rational number, it is automatically not an irrational number.

Step-by-step explanation:

a) Let X be the random variable the number of customers asking for water.

X ~B(10,0.6)

= P(X = 6) =( 0.6)6 ( 0.4)4 10!/6 !*4!

= 0.2508

Y ~B(10,0.4)

= P(Y = 4)=( 0.6)6 ( 0.4)4 10!/6 !*4!

= 0.2508

The probability that exactly 6 ask for water with their meal is calculated by binomial distribution and the value is P ( x = 6 ) = 25.08 %

What is a Binomial Distribution?

The binomial distribution is a type of probability distribution that predicts the likelihood of obtaining one of two outcomes given a set of inputs. It summarizes the number of tries where each trial has the equal chance of producing the same result.

The formula for Binomial Distribution is given by

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

where

n = number of trials

x = number of successes

p = probability of getting a success in one trial

q = probability of getting a failure in one trial

q = 1 - p

Given data ,

Let the probability that exactly 6 ask for water with their meal be P ( x = 6 )

Now , an average of 3 out of every 5 customers ask for water with their meal

So , the probability of getting a success p = 3/5 = 0.6

The probability of getting a failure q = 1 - p = 0.4

The number of trials = 10

The number of successes x = 6

So ,

Probability that exactly 6 ask for water with their meal be P ( x = 6 ) is

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

Substituting the values in the equation , we get

P ( x = 6 ) = [ 10! / ( 4 )! 6! ] ( 0.6 )⁶( 0.4 )⁴

On simplifying the equation , we get

P ( x = 6 ) = 0.2508

P ( x = 6 ) = 25.08 %

Therefore, the value of  P ( x = 6 ) is 25.08 %

Hence , probability that exactly 6 asks for water is 25.08 %

Answer:

Sides = 3.2

Diagonals = 4.5

Shape = Square

Step-by-step explanation:

a) i) Distance from P to Q= 3.162278 which is approx 3.2.

So to calculate your answer you use the distance formula. The formula is the square root of (x2 - x1) + (y2 - y1).

So all sides of the shape have a length of 3.2 because the shape is a square.

DIAGONALS:

QS = 4.472136 approx 4.5

For:

(X1, Y1) = (-3, -2)

(X2, Y2) = (-1, 2)

We use the same formula for distance.

B) The shape is a square

To determine which of the rectangles has a different area, the areas of the four rectangles must be calculated. The rectangle with a different area is rectangle b

The dimension of the 4 rectangles are:

a. length: 4x and width: 4

b. length: 11 and width: x

c. length: 2 and width: 8x

d. length: 16x and width: 1

The area of a rectangle is:

[tex]Area = Length \times Width[/tex]

Rectangle (a)

[tex]Area = 4x \times 4[/tex]

[tex]Area = 16x[/tex]

Rectangle (b)

[tex]Area = 11 \times x[/tex]

[tex]Area = 11x[/tex]

Rectangle (c)

[tex]Area = 2 \times 8x[/tex]

[tex]Area = 16x[/tex]

Rectangle (d)

[tex]Area = 16x \times 1[/tex]

[tex]Area = 16x[/tex]

Rectangles (a), (c) and (d) have the same area (i.e. 16x) while rectangle (b) has 11x as its area.

Hence, the rectangle with a different area is rectangle (b).

Answer:

Step-by-step explanation:

Well believe it or not, that is not a simple question. Just look at what you left us to define. Your talking (for example) about a square and wondering what the vertex of B is called (other than a vertex.)

I think vertex is the only thing you can call B. But then there's a problem. What do you call the points on a segment? ___________? There are endpoints, but what's between those endpoints? I think you would just give them letter names and call them points. A point is dimensionless and there an infinite number of them in a segment.

Answer:

165.7 or 166

Step-by-step explanation:

since the adjacent has already been given which is 113 you have to use the cos ratio to find the hypotenuse

cos47=adjacent/hypotenuse

cos47=113/h

cos47h/cos47=113/cos47

hypotenuse=166

I hope this helps

Answer:

Hypotenuse is 165.689

Step-by-step explanation:

For this question you will be using cosine.

You start solving this problem as C (cosine) = A/H (adjacent over hypotenuse).

COS(47) / 1 = 113/H

Meaning cosine of 47 over 1 is equal to 113 over H (hypotenuse).

Next you cross multiply leaving you with 113/ COS47 = COS47 x H

Next you divide both sides by COS47 x y

and divide 113 by COS47 and get your answer.

Answer:

Below.

Step-by-step explanation:

If the length is x then the width is x-9 inches.

Perimeter

= 2L + 2W = 86

2x + 2(x - 9) = 86

4x - 18 = 86

4x = 104

x = 26

So the length is 26 inches and the width is 17 inches.
