Answer:

  (-2)

Step-by-step explanation:

Put the point values in the given equation to see what the missing number is.

  y = 1/2x + (_)

  2 = 1/2(8) + (_) . . . . . substitute the given values

  2 = 4 + (_) . . . . . . . .  simplify

  -2 = (_) . . . . . . . . . . . subtract 4

The green ? should be filled with -2.

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

Answer:

[tex]\huge\boxed{\sf Solution\ Set = \{x,y\} = \{1,2\}}[/tex]

Step-by-step explanation:

3x + 4y = 11 ----------------------(1)

x = 15 - 7y   ----------------------(2)

Put Eq. (2) in (1)

3(15 - 7y) + 4y = 11

45 - 21y + 4y = 11

45 - 17y = 11

Subtracting 45 to bot sides

-17y = 11 - 45

-17y = -34

Dividing both sides by -17

y = -34 / -17

y = 2

[tex]\rule[225]{225}{2}[/tex]

Put y = 2 in Eq. (2)

x = 15 - 7(2)

x = 15 - 14

x = 1

[tex]\rule[225]{225}{2}[/tex]

Solution Set = {x,y} = {1,2}

[tex]\rule[225]{225}{2}[/tex]

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

Answer:

so for the first one the cost for all the tickets is 412

for the last one the cost is 333

Step-by-step explanation:

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 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:

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.

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
