What is the equation of 35?​

Answers

35 - X = 5

Simplifying

35 + -1X = 5

Solving

35 + -1X = 5

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '-35' to each side of the equation.

35 + -35 + -1X = 5 + -35

Combine like terms: 35 + -35 = 0

0 + -1X = 5 + -35

-1X = 5 + -35

Combine like terms: 5 + -35 = -30

-1X = -30

Divide each side by '-1'.

X = 30

Simplifying

X = 30

Lyn either travels by bus or walks
when she visits the shops.
The probability that she catches
the bus To the shops is 0.2
The probability that she catches
the bus FROM the shops is 0.6

0.2
Walk
a) Complete the tree diagram.
b) Show that the probability that Lyn
walks at least one way is 0.88.​

Answers

I’m forced to write an explanation, sorry for the useless text

The probability tree has been drawn below and the  probability that Lyn

walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks.

What is probability?

The probability of an event occurring is defined by probability.

Do not take underestimate probability it has several uses in daily life whether forecasts like that.

As per the given probability tree,

(a)

The probability in branches adds to 1 thus,

0.2 + probability that she walks to the shop = 1

Probability that she walks to the shop  = 1 - 0.2 = 0.8

The probability in the same branches multiplies as,

The probability that she took a bus to the shop x from the bus she again took the bus.

Similarly, the tree diagram has been drawn below.

(b)

The probability is 0.88 lies in that Lyn walks at least one way 0.88 is when she reaches the shop by bus and from the bus, she walks.

Hence "walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks".

A.6 inches
B.8 inches
C.10 inches
D.12 inches

Answers

The answer Is C. 10 inches
Answer: 6 inches

Step-by-step explanation:
volume of a rectangular prism is V=LWH
L is length and that is 20
W is width and that is 20
H is height and that is 6
The reason that L and W are 20 is because you would multiply those to get the base, and the base is already given, 400.
Since you know the volume is 2,400, a quick trick is that you divide 2,400/400. That equals 6.
So 20 x 20 x 6 = 2400

fair- sided coin is tossed 18 times . Which of the experimental outcomes is most consistent with theoretical outcomes
A) 4 heads and 14 tails
B) 6 heads and 12 tails
C) 9 heads and 9 tails
D) 10 heads and 8 tails
HELP WILL GIVE BRAINLY

Answers

Answer:

C) 9 heads and 9 tails

Step-by-step explanation:

if a fair sided coin is tossed, the probability of obtaining either heads or tails is 50%

If the coin is tossed 18 times, we would expect to see the same probability outcome which is 50% heads and 50% tails.

which corresponds to 9 heads and 9 tails.

Answer:

Step-by-step explanation:

Each throw is independent of any other throw. The probability of getting a head or tail is 1/2, so you should expect to flip as many heads as tails. Answer C shows that even split.
