Help please !??? This is kinda confusing

Answer:

Point M is the midpoint of AB. If the coordinate of A are (-3,6) and the coordinates of M are (-5,2), what are the coordinates of B?

Step-by-step explanation:

The total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 fraction of all games at the tournament Anita plays the game.

We have given that,

Of the 10 kids in a chess club, 5 are left-handed and 5 are right-handed.

A permutation can be defined as the number of ways a set can be arranged, order matters but in combination, the order does not matter.

We have 5 girls and 5 boys in a chess club:

There are a total of 5×5 games girls play against a boy.

= 5×5

= 25

The number of games a girl play against another.

It is a combination problem so the total number of games:

= 10

A fraction of the games are boy-versus-boy:

The number games boy-versus-boy = 10

The number games Boy vs Boy & Girl vs Girl & Boy vs Girl

= 10+10+25

=  45

So the fraction = 10/45 ⇒ 2/9

If Anita is one of the club members then Anita will have to play against 9 people at the tournament.

Total number of games = 45

Then the fraction = 9/45 ⇒ 1/5

Thus, the total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 fraction of all games at the tournament Anita play the game.

Answer:

let the width be x

so 3x × x = 48

=> 3x^2 = 48

=> x^2 = 16

=> x = 4

So the length = 4×3 = 12 inches

breadth= 4 inches

Answer:

Option A.

Step-by-step explanation:

√18x÷√32

√18x/√32

√18x/32

√9x/16

9 and 16 are perfect squares

=3√x/4.

Option A

Answer: 4 bags

Step-by-step explanation:

2 cups  =  16 ounces

So  using a proportion

16 / 8   =  x  /  60          where  x  is the number of ounces we need to buy

cross-multiply

16 * 60   =  8 * x

960   = 8 x

960 / 8   = x  =   120    ounces

The  number of  bags  we  need   =    ceiling  [ 120/32 ]    = 4 bags

Answer:

A. 4/12, C. 1/3

Step-by-step explanation:

2/6 can be divided by 3. Therefore, the fraction is 1/3.

A. 4/12 can be divided by 4. This means the fraction will be 1/3. Because 1/3 is equal to 1/3, this option is correct.

B. 1/2 cannot be simplified. Because 1/3 is not equal to 1/2, this option is not correct.

C. 1/3 cannot be simplified. Because 1/3 is equal to 1/3, this option is correct.

D. 3/8 cannot be simplified. Because 3/8 is not equal to 1/3, this option is not correct.

An expression with more than three terms is named simply by its number of terms. For example a polynomial with five terms is called a five-term polynomial.

Answer:

70°

Step-by-step explanation:

[tex] m\widehat {BC} = 90\degree - m\widehat {CD} [/tex]

[tex] m\widehat {BC} = 90\degree -20\degree [/tex]

[tex] m\widehat {BC} = 70\degree [/tex]

Answer:

Step-by-step explanation:

x = -1:  2(3)^(-1) = 2(1/3) = 2/3

x = 0:  2(3)^0 = 2(1) = 2

x = 1:    2(3)^1 = 6

x = 2   2(3)^2 = 18

Answer:

A

Step-by-step explanation:

∠4 and ∠8 are corresponding angles

corresponding angles are congruent ( equal to each other )

so if ∠4 = 100° then ∠8 also equals 100°

Answer:

A

Step-by-step explanation:

8 is equal to 4(100) because it is corresponding angle, corresponding angle are equal to each other...If 4 is 100 then 8 will be 100

Answer:

b corresponding angles

Answer:

Where's the triangle? Do you have an image?

Answer:

Step-by-step explanation:

Given:

A shelf is built on a wall. The angles of the triangle are given as (x + 3)°, (2x - 18)° and 90°

We need to determine the value of x.

Value of x:

By triangle sum property, the angles in a triangle always add up to 180°

Thus, we have;

Simplifying, we get;

Subtracting both sides by 75, we get;

Dividing both sides of the equation by 3, we get;

Thus, the value of x is 35.

Answer:

x = 30

Step-by-step explanation:

correct me if i am wrong but i think you have to

a.) change the denominator's to be the same :

ten is a common denominator therefore you times the second expression by two ( x/5 becomes 2x/10 )

b.) put the formula back together :

3x/10 + 2x/10 = 15

5x/10 = 15

5x = 150

x = 30

Answer:

Step-by-step explanation:

============================================================

Explanation:

Angles 1 and 3 are vertical angles. Note how line t and line r intersect to form an X shape. Angle 1 and angle 3 are opposite angles in this X configuration, which is what makes them vertical angles. Vertical angles are always congruent.

Angle 1 is congruent to angle 2 if and only if both angles were 90 degrees (note the angles are supplementary). Otherwise, they aren't congruent. That allows us to rule out choice A. Choice C is ruled out for the exact same reason.

Answer:

a)  [tex]P(10)=0.2061[/tex]

b)  [tex]P(9\ or\ 12)=0.3172[/tex]

c)  [tex]P(X>10)=0.51545[/tex]

Step-by-step explanation:

From the question we are told that:

Probability of Same day resolution [tex]P=70\%=>0.7[/tex]

Probability of Another day resolution [tex]Q=1-P=>30%=>0.3[/tex]

Sample size [tex]n=15[/tex]

a)

Generally the equation for Probability 10 of the problems can be resolved today is mathematically given by

Since

 [tex]P(X)=^{n}C_{x}*p^{x}*Q^{n-x}[/tex]

 [tex]P(10)=^{15}C_{10}*p^{10}*Q^{15-10}[/tex]

 [tex]P(10)=\frac{15!}{10!(15-10)!*0.70^{10}*0.30^5}[/tex]

 [tex]P(10)=0.2061[/tex]

b)

Generally the equation for Probability 9 or 12 of the problems can be resolved today is mathematically given by

 [tex]P(9)=\frac{15!}{9!(15-9)!*0.70^{9}*0.30^6}[/tex]

 [tex]P(9)=5005*2.942*10^{-5}[/tex]

 [tex]P(9)=0.1472[/tex]

OR

 [tex]P(12)=\frac{15!}{12!(15-12)!*0.70^{12}*0.30^3}[/tex]

 [tex]P(12)=455*3.737*10^{-4}[/tex]

 [tex]P(12)=0.17[/tex]

Therefore Probability 9 or 12 of the problems can be resolved today is

 [tex]P(9\ or\ 12)=P(9)+P(12)[/tex]

 [tex]P(9\ or\ 12)=0.1472+0.17[/tex]

 [tex]P(9\ or\ 12)=0.3172[/tex]

c)Generally the equation for probability more than 10 of the problems can be resolved today is mathematically given by

 [tex]P(X>10)=P(11)+P(12)+P(13)+P(15)[/tex]

Where

 [tex]P(11)=\frac{15!}{11!(15-11)!*0.70^{11}*0.30^4}[/tex]

 [tex]P(11)=0.2186[/tex]

 [tex]P(13)=\frac{15!}{13!(15-13)!*0.70^{13}*0.30^2}[/tex]

 [tex]P(13)=0.0916[/tex]

 [tex]P(14)=\frac{15!}{14!(15-14)!*0.70^{14}*0.30^1}[/tex]

 [tex]P(14)=0.0305[/tex]

 [tex]P(15)=\frac{15!}{15!(15-15)!*0.70^{15}*0.30^0}[/tex]

 [tex]P(15)=0.00475[/tex]

Therefore

 [tex]P(X>10)=0.2186+0.0916+0.0305+0.00475+0.17[/tex]

 [tex]P(X>10)=0.51545[/tex]

Answer:

1/12

Step-by-step explanation:

1/4 X 1/3 = 1/12

Answer:

1/12

Step-by-step explanation:

When multiplying fractions, you multiply it like normal numbers, so 1 is multiplied by 1, and 3 is multiplied by 4.

For example:

3/4 x 9/10 would be equal to 27/40 because the 3 is multiplied by 9 and 4 is multiplied by 10.

3 x 9 = 27

4 x 10 40

27/40

Therefore on your question it would be 1/12.
