A 6-sided die must be rolled 36 times before sequence 65 appears. (i.e., a 6 followed by a 5)
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Let E as the expected rolls, and E₆ as the expected rolls given we rolled a 6.
Given that we rolled a 6, there is a 1/6 chance that two rolls will be enough, a 4/6 chance that we didn't roll a 5 or 6 and so spent two rolls, and a 1/6 chance that we rolled a 6 and only wasted one roll:
E₆ = (1/6)2 + (4/6)(E+2) + (1/6)(E₆ + 1)
Rearrange the terms and apply arithmetics operations
E₆ = (4E + 11)/5
According to the question,
We have 5/6 that we rolled [1,5]
So we wasted a roll, and 1/6 that we rolled a 6,
E = (1/6)×E₆ + (5/6)×(E+1)
Substitute the value of E₆ in the equation,
E = (1/30)×(4E+11) + (5/6)×(E+1)
E = 36
Hence, a 6-sided die must be rolled 36 times before sequence 65 appears.

What is the domain of the function f(x)=-2x + 9 when the range is {-7, 1,9}?
Domain f(x) = 23, 7, -9 for range of { -7, 1, 9}
The domain is f(x) = -2x + 9, and the range of the function is {-7, 1, 9}
To find the domain of the function we have to put the value of x as -7, 1, and 9.
Put x = -7 we have
f(x) = -2x + 9
= -2(-7) + 9
= 14+9
= 23
Now x = 1
f(x) = -2(1) + 9
= -2+9
= 7
Now x = 9
f(x) = -2(9) + 9
= -18 + 9
= -9
Therefore we get the domain of function as 23, 7, -9 for the range {-7, 1, 9}.

Eshaal is creating a model of a pyramid. The model created will need to be scaled up from the blueprint.
If segments DE and AB are parallel, which of the following expressions will help Eshaal determine the length of segment BC?
BC = CE
BC equals AC times CE all over CD
BC equals AC times DE all over CE
BC = AC
Answer:
See attachment
PS:
Can I have Brainliest?
The correct statement is BC equals to AC times CE all over CD.
We have, If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally. this is known as the triangle proportionality theorem.
Given, DE and AB are parallel
So, [tex]\frac{BC}{CE} =\frac{AC}{CD}[/tex]
[tex]BC = \frac{AC\times CE}{CD}[/tex]
Therefore in statement form we say that BC equals to AC times CE all over CD.

A high school soccer team is going to Columbus to see a professional soccer game. A coordinate grid is superimposed on a highway map of Ohio. The high school is at point (2, 4) and the stadium in Columbus is at point (7, 6). One unit on the map is 3 miles. The approximate distance between the high school and the stadium to the nearest mile is Answer miles.
Answer:
16 miles
Step-by-step explanation:
Given that :
1 unit = 3 miles
High School = (2, 4)
Stadium = (7, 6)
Approximate distance between high school and stadium :
Distance between High school and Stadium
x1 = 2 ; y1= 4 ; x2 = 7 ; y2 = 6
Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Distance = sqrt((7 - 2)^2 + (6 - 4)^2)
Distance = sqrt((5^2 + 2^2))
Distance = sqrt(25 + 4)
Distance =5.3851648 units
1 unit = 3 miles
Approximate Distance in miles :
3 * 5.3851648 = 16.155494
Approximate distance = 16 miles

i need to solve this questions the sum of two numebers is 5.036 .one number has a 4 in the tenths place and a 7 on the thousandths place.the other number has a 1 in the ones place and and an 2 in the hundredths place. what are the two numbers?
Two numbers, whose sum is 5.036, are 3.407 and 1.629.
Decimals numbers are numbers containing wholes and parts separated by a decimal point ".".
In adding or subtracting decimal numbers, first is to align the decimal point of the decimal numbers. Add/subtract the digits from right to left.
If we have two numbers, one number has a 4 in the tenths place and a 7 on the thousandths place, the second number has a 1 in the ones place and and an 2 in the hundredths place, and their sum is 5.036, we can write that as:
_ . 4 _ 7
+ 1 . _ 2 _
5 . 0 3 6
7 and 9 when added will give a sum of 16.
_ . 4 _ 7
+ 1 . _ 2 9
5 . 0 3 6
Since there is 1 from 16 earlier, 1 and 2 when added will give a sum of 3.
_ . 4 0 7
+ 1 . _ 2 9
5 . 0 3 6
4 and 6, when added will give a sum of 10.
_ . 4 0 7
+ 1 . 6 2 9
5 . 0 3 6
Since there is 1 from 10, 1 added to 1 and 3 will give a sum of 5.
3 . 4 0 7
+ 1 . 6 2 9
5 . 0 3 6
Hence, the two numbers are 3.407 and 1.629.

Joel cut the longest piece of fencing in order to make a right triangle. Find the perimeter of Joel's fence.
He needs 20 minutes to install all of the fence.
Since we have given that
Dimensions of triangle he has to use for fencing are
15 feet, 8 feet, and 20 feet.
1) For making it a right triangle it must satisfy the "Pythagorus theorem" which states that
H²= B²+P²
⇒ 20²= 15²+8²
⇒ 400 ≠ 225+64
⇒ 400≠ 289
No, it will not be able to make a right triangle.
2) Joel cut the longest piece of wood in order to make a right triangle.
So, from above we get that
√289= 17 FEET
So, Longest side must be 17 feet.
It is takes him 30 seconds to install each foot of fencing,
Total perimeter of fencing will be
17+15+8=40 feet
So, for 1 foot he needs = 30 seconds
For 40 feet , he will need
40×30=1200 seconds
1200/60
= 20 MINUTES
Hence, he needs 20 minutes to install all of the fence.

in a different plan for area codes, the first digit could be any number from 4 through 8, the second digit was either 4 5 6 or 7, and the third digit could be any number except 2 or 7 with this plan, how many different area codes are possible?
There are 160 possibilities for area codes
We are required to find all the combinations for different area codes
It is given to us that the conditions for the tree digit area code are:
first digit could be any number from 4 through 8,
the second digit was either 4 5 6 or 7, and the third digit could be any number except 2 or 7
Using the conditions above, the digits which can be first digit of code = 4 through 8 =4,5,6,7,8
the digits which can be second digit of code= 4,5,6,7
the digits which can be third digit of code = 0,1,3,4,5,6,8,9
number of possibilities for first digit= 5
number of possibilities for second digit=4
number of possibilities for third digit= 8
Therefore, total number of possibilities of code = number of possibilities of first digit x number of possibilities of second digit x number of possibilities of third digit = 5 x 4 x 8=160
Therefore, there are 160 possibilities for area codes
