Answer:

C. 3/8

Step-by-step explanation:

To solve think about how many sections there truly are. The 5 section represents 3 parts, the 2 section represents 2 parts, and the 1, 4, 3 sections represent 3 parts in total. This means overall there are 8 parts to this spinner. Since 5 takes up 3 of these 8 parts, the probability of the pointer landing on 5 is 3/8.

Answer:

ŷ = -0.07637X + 61.36874

Step-by-step explanation:

Score, x :

545

595

640

675

705

750

Interest %, y:

18.982

17.967

12.218

8.612

Using the ordinary least square regression calculator :

The equation of best fit obtained is :

ŷ = -0.07637X + 61.36874

Slope = - 0.07637 (depicts a negative relationship between the variables).

Intercept = 61.36874

Score, X = explanatory variable ; Interest rate, Y = response variable

The sandwich will cost $3.1.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Let's say the cost of 1 drink is d while the cost of 1 sandwich is s

Now,

Given that,

A drink and a sandwich together cost $4.85.

So,

s + d = 4.85

And,

The sandwich cost $1.35 more than the drink.

So,

s = 1.35 + d

By using substitution

s = 1.35 + 4.85 - s

2s = 6.2

s = 3.1

Hence "The sandwich will cost $3.1".

Answer:

The trial are not dependent

Step-by-step explanation:

The following four conditions must be met before Binomial probability experiment can be define, they are:

[1]. Each trial is independent, [2]. the trial must have two outcomes that is failure or success, [3]. fixed number of trials and [4]. success probability for each trial is the same.

Thus, the number of ways to choose the positions for success is given in equation (1) below as:

P(x) = n Cₓpˣ [1 - p]ⁿ⁻ˣ. ----------------------------------------------------------------------(1).

Where n-x = failure and 1 - p = probability and x = success.

For this question, three of the conditions mentioned above are met except for condition number one. This is so because the events are dependent. Therefore, the binomial condition that is not met is Each trial is independent.

NB: Why the events are dependent is because if the each husband divorce his wife, then the wife is also divorced.

Answer:

x = -8

Step-by-step explanation:

If the line is parallel to the y axis, that means it will be a vertical line.

Vertical lines have an equation of x = , because the line will only go through one x value.

They also will not have a slope, because their slope is undefined.

So, the correct answer is x = -8

Answer:

The two numbers are 45 and 46.

Step-by-step explanation:

Given: Sum of two numbers=91

To find: Two consecutive numbers which add up to form 91

Solution:

Consecutive numbers are those numbers which have a difference of one between them.

First divide 91 into two halves, we get 45.5

Now we know 45.5+45.5=91

But the numbers should differ by one in order for them to be consecutive.

Hence we subtract 0.5 to get one number and add 0.5 to get the second number from 45.5

So, the two numbers are 45.5–0.5=45

and 45.5+0.5=46

Hence the two numbers are 45 and 46.

Answer:

a)

If Beth’s parents are not albino, but she has an albino brother (aa), then each parent must have the allele a. In order for someone who is not albino to be able to have an albino child of albinism, they must have type Aa.

b)

P(AA) = 0.5(0.5) = 1/4  CHANCE

P(Aa) = 0.5(0.5) = 1/4  CHANCE

P(aa) = 0.5(0.5) = 1/4   CHANCE

c)

the new probabilities are:

P(AA | not aa) = 1/3  

P(Aa | not aa) = 2/3

Step-by-step explanation:

   Given the data in the question;

a) Beth’s parents are not albino, but she has an albino brother. This implies that both of Beth’s parts have type Aa. Why?

If Beth’s parents are not albino, but she has an albino brother (aa), then each parent must have the allele a. In order for someone who is not albino to be able to have an albino child of albinism, they must have type Aa.

To be fully albino you must be aa and must also have at least one a as well as have a child with someone who also has has at least a.

b) Which of the type aa, Aa, AA could a child of Beth’s parents have? What is the probability of each type?

                             A                 a

A                         AA                Aa

a                         aA                 aa

so, Since each type is equally likely, and each is inherited independently of each other then,

P(AA) = 0.5(0.5) = 1/4  CHANCE

P(Aa) = 0.5(0.5) = 1/4  CHANCE

P(aa) = 0.5(0.5) = 1/4   CHANCE

c) Beth is not albino. What are the conditional probabilities for Beth’s possible genetic types, given this fact?

First we rule out aa, since Beth is not an Albino.

the new probabilities are:

P(AA | not aa) = 1/3  

P(Aa | not aa) = 2/3

2x<9+5

2x<14

2x/2<14/2

x<7

Answer:

[tex]\boxed {\boxed {\sf x <7}}[/tex]

Step-by-step explanation:

To solve the inequality you must isolate the variable, which is x.

[tex]2x-5 < 9[/tex]

5 is being subtracted from 2x. The inverse of subtraction is addition, so add 5 to both sides of the equation.

[tex]2x-5+5 < 9+5[/tex]

[tex]2x < 14[/tex]

x is being multiplied by 2. The inverse of multiplication is division, so divide both sides by 2.

[tex]\frac {2x}{2} < \frac {14}{2}[/tex]

[tex]x <7[/tex]

The solution to this inequality is x <7

Answer:

30

Step-by-step explanation:

All angles measure up to 180.

3x+2x+1x=180

6x=180

1x=30

Answer:

L = 90

K = 60

M = 30

Step-by-step explanation:

2x + 3x + x = 180

6x = 180

divide by 6

x = 30

3(30) = 90

2(30) = 60
