What are the places in decimals called.

Answer: the tenths place

Step-by-step explanation:

suppose a traveler is selected from this sample at random. Let event A = home sharing and event B = fly. Are events A and B independent? No, P(A) = P(A|B). No, P(A) ≠ P(B|A). Yes, P(A) = P(A|B). Yes, P(A) ≠ P(B|A).

Answers

Answer:

Yes, P(A) = P(A|B)

Step-by-step explanation:

The context of the question is incomplete but I've assumed logically what it might be;

Whether a traveller flies or doesn't fly to their destination is unrelated to whether they home share or not;

Therefore, they are independent;

Independent events are events where the outcome of one event has no effect on the probabilities of the outcomes from a second event;

This can be represented mathematically as: P(A) = P(A|B);

The corollary of this is P(B) = P(B|A);

A common example easily understood would be if you flip a coin, there is a 50% chance of heads and 50% chance of tails;

If I flip and gets a heads first, the probability of getting a heads or tails on the second, third or tenth flip is going to be unchanged, i.e. 50% chance of heads and 50% chance of tails

Two systems of equations are shown:

System A System B

3x + 2y = 3 −x − 14y = 1

−2x − 8y = −1 −2x − 8y = −1

Which of the following statements is correct about the two systems of equations?

A.)The value of x for System B will be one-third of the value of x for System A because the coefficient of x in the first equation of System B is one third times the coefficient of x in the first equation of System A.

B.) The value of x for System A will be equal to the value of y for System B because the first equation of System B is obtained by adding −4 to the first equation of System A and the second equations are identical.

C.) They will have the same solution because they represent the same lines when plotted on the coordinate axes.

D.)They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.

30×60×90 right triangle has side ratios as:

s : l : h = 1 : √3 : 2, where s- short leg, l - long leg, h - hypotenuse

45×45×90 right triangle has side ratios as:

l : l : h = 1 : 1 : √2, where l- legs, h- hypotenuse

If you know one of the sides its easy to find the missing ones.

a) 30×60×90 right triangle

Given l = 12s : 12 : h = 1 : √3 : 2CB = s = 12 / √3 = 12√3/3 = 4√3 AB = h = 2s = 2*4√3 = 8√3

b) 45×45×90 right triangle

Given l = √22BC = l = √22AB = l√2 = √22×√2= √44 = 2√11

c) 30×60×90 right triangle

Given h = 20√6s : l : 20√6 = 1 : √3 : 2BC = s = h/2 = 20√6/2 = 10√6AC = l = s√3 = 10√6×√3 = 10√18 = 10×3√2 = 30√2

Answer:

y=mx+c

⟹(y)−c=(mx+c)−c

⟹y−c=mx+(+c−c)

⟹y−c=mx+0

⟹y−c=mx

⟹mx=y−c

⟹mx×(1m)=(y−c)×(1m)

⟹x×(mm)=1m(y−c)

⟹x×1=1m(y−c)

⟹x=1m(y−c)

1/3(x+3/5)=3

x=36/5

x=42/5

x=48/5

Answers

Answer:

x = 42/5 is the answer to this question

Option B is correct, the solution to the equation is x = 42/5.

The given equation is 1/3(x + 3/5) = 3.

We have to solve for x:

x is the variable in the equation.

Multiply both sides by 3 to get rid of the fraction:

1/3(x + 3/5) × 3 = 3 × 3

(x + 3/5) = 9

Subtract 3/5 from both sides to isolate the x term:

(x + 3/5) - 3/5 = 9 - 3/5

x = 9 - 3/5

Now, to combine the terms on the right side:

x = 45/5 - 3/5

x = 42/5

Therefore, the solution to the equation is x = 42/5.

Sweet Treats Bakery sells gourmet cookies. If three gourmet cookies cost $7.95, then
how much will it cost to buy 10 cookies?

Answers

Answer:

$26.50

Step-by-step explanation:

7.95/3=2.65

2.65*10=26.5

Answer:

$26.50

Step-by-step explanation:

If 3 cookies are 7.95, we can do 7.95/3 to find the cost of 1 cookie.

1 cookie is 7.95/3 = 2.65.

Now, we can find the cost of 10 cookies by simply multiplying 10 to the cost of 1 cookie, which is 2.65*10 = 26.5.

10 cookies will cost $26.50.

Grogg draws triangle ABC. Side BC is 4 inches shorter than side AB. and side AC is 6 inches longer than side BC. The perimeter of the triangle is 31 inches. What is the length of side AB?

Answers

Answer:

AB = 11

Step-by-step explanation:

AB = x

BC = x - 4

AC = 6 + BC Substitute BC

AC = 6 + (x - 4)

AC = 2 + x

The perimeter of the triangle is 31

Perimeter = AB + BC + AC perimeter is the sum of the sides

31 = (x )+ (x - 4 ) + (2 + x)

31 = 3x - 2

33 = 3x

11 = x

AB = x = 11 inches

Check:

AB = x ; AB = 11

BC = x - 4; BC = 11 - 4; BC = 7

AC = 2 + x; AC = 2 + 11; AC = 13

P = 11 + 7 + 13

= 31
