Answer:
He was incorrect because...
Step-by-step explanation:
Although there is a CHANCE that a 1 will be rolled. There is also a chance to rolls all 6's, or all 5's for example. The chance that a 1 will be rolled is 1/6, or ~16.67%.
Joe is not correct.
We have a statement said by joe - if you roll a number cube 6 times, one of those rolls will be a 1.
We have to investigate whether joe is right or not?
What are all possible outcomes if you roll a number cube?When you roll a number cube the possible outcomes are - 1, 2, 3, 4, 5, 6.
If we consider statement said by joe - he expressed the certainty of the occurrence of 1. According to him, if you roll a number cube 6 times, then the probability of the Event (say A) - one of those rolls will be 1 is :
P(A) = 1 (the event will 100% occur)
However, when a number cube is rolled 6 times, the total number of possible outcomes = 6 x 6 = 36. The total number of favorable outcomes are = 6.
Therefore, the probability that the event - one of the rolls will be 1 is
[tex]P(A) =\frac{6}{36}= 0.16[/tex]
This means that the probability of occurrence of event is 16%.
Hence, Joe is not correct.

Laurie is trying to stay within 10 feet of her current diving depth of -30 feet (with regard to sea level) so that the light is still good but she can be close to the sea life during her scuba dive Which two equations can be used to find the minimum and maximum depths Laurie wants to stay between?
Answer:
It should be the first one
Step-by-step explanation:
since positive ten would represent going further up and negative ten going further down, the diver would be within ten feet of her current position
Answer:
A) -30 - x = 10 and -30 - x = –10
Step-by-step explanation:
Part 1:
1) Isolate the variable x
-30 - x = 10
-x = 40
2) Multiply both sides by -1
x = -40
Therefore -30 - x = 10 is correct
Part 2:
1) Isolate the variable x
-30 - x = –10
-x = 20
2) Multiply both sides by -1
x = -20
Therefore -30 - x = –10 is also correct
Final Answer: -30 - x = 10 and -30 - x = –10

!!!!!!!!!!!!!!
Answer:
look at the picture i have sent
In the right ABC above, the length of the side BC is 4.
What is the Pythagoras theorem?The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]
Given;
Side BA= [tex]\sqrt{11}[/tex]
Side AC= [tex]\sqrt{5}[/tex]
BC^2=BA^2+AC^2
BC^2= ([tex]\sqrt{11}[/tex])^2 +([tex]\sqrt{5}[/tex])^2
BC^2= 11+5
BC^2= 16
BC= 4

Given the point (x, y) = (3, 8), find x' of the image point with respect to an axis rotated 60.
3/2 + 4√3
(3√3)/2 - 4
(3√3)/2 + 4
The value of x', the image point with respect to an axis rotated 60 is 3/2 + 4√3
How to determine the x' coordinate?The point is given as:
(x, y) = (3, 8)
The angle of rotation is given as:
θ = 60
The image of rotation is calculated using:
x = x'cosθ - y'sinθ
y = x'sinθ + y'cosθ
So, we have:
3 = x'cos(60) - y'sin(60)
8 = x'sin(60) + y'cos(60)
Evaluate cos(60) and sin(60)
3 = 1/2x' - y'√3/2
8 = x'√3/2 + 1/2y'
Multiply the second equation by √3
8√3 = 3/2x' + √3/2y'
Add this equation and the first equation to eliminate y'
3 + 8√3 = 1/2x' + 3/2x'
Evaluate the sum
3 + 8√3 = 2x'
Divide through by 2
x' = 3/2 + 4√3
Hence, the value of x' is 3/2 + 4√3

Answer:
5. a = 4
7. x = -8
9. x = -1
11. p = 1.1
13. x = -1
15. x = -4
Step-by-step explanation:
2.9a = 11.6
2.9a/2.9 = 11.6/2.9
a = 4
-3.7x = 29.6
-3.7x/-3.7 = 29.6/-3.7
x = -8
(x-5)(-3) = 18
(x-5)(-3)/-3 = 18/-3
x-5 = -6
x-5+5 = -6+5
x = -1
3.6 = -2p+5.8
3.6-5.8 = -2p+5.8-5.8
-2.2 = -2p
-2.2/-2 = -2p/-2
1.1 = p
2x+6 = -4x
2x+6-6 = -4x-6
2x = -4x-6
2x+4x = -4x-6+4x
6x = -6
6x/6 = -6/6
x = -1
21-6x = -11-14x
21-6x-21 = -11-14x-21
-6x = -14x-32
-6x+14x = -14x-32+14x
8x = -32
8x/8 = -32/8
x = -4
Answer:
5.) a= 4
7.) x= -8
9.)x= -1
11.) p= 1.1
13.) x= -1
15.) x= -4
Step-by-step explanation:
5.) divide 11.6 by 2.9a
7.)divide 29.6 by -3.7u
9.) Divide by sides by -3. simplify. Add 5 to both sides. then simplify again x= -1
11.) subtract 5.8 from 3.6 . you're left with -2p=-2.2 divide both sides by -2. you get p=1.1
13.)Subtract 6 from both sides. You get 2x= -4x-6. Add 4x to both sides. then divide -6 by 6 you get x=-1
15.) Simplify both sides of the equation, so add 14x to -6x +21 side, you get 8x= -32 then divide -32 by 8x you get -4
