Eva payrolls for on a number cube and the number of cubes roll 24 times then what is a reasonable prediction for the number of successful Rolls
Answer:
The reasonable prediction for successful rolls is 4.
Step-by-step explanation:
Assuming the rolling cube is a fair 6 sided cube, so the probability of success of one roll is given as
[tex]P(Success)=\dfrac{Number\ of\ successful\ events}{Number\ of\ total\ events}[/tex]
[tex]P(Success)=\dfrac{1}{6}[/tex]
The total success is given as
[tex]P(Total\ Success)=P(Success)\times Number\ of\ events[/tex]
For 24 rolls it is given as
[tex]P(Total\ Success)=P(Success)\times Number\ of\ events\\P(Total\ Success)=\dfrac{1}{6}\times 24\\P(Total\ Success)=4[/tex]
So the reasonable prediction for successful rolls is 4.

Mark rides his bike from his house to the closest edge of the park, across the length of the park, and then back home. The distance from his house to the closest edge of the park is 0.9 km and the distance from the far side of the park to his house is 1.6 km. The map shows the path Mark took on his bike. If ∠B = 85° on the map, then use the law of cosines to determine the length of the park in kilometers.
Answer:
The length of the park is approximately 1.77 kilometers
Step-by-step explanation:
The law of cosines is most appropriate when the measures of two sides and the included angle formed n=by the path of motion is known
The given parameters of the question are;
The distance from Mark's house to the edge of the park, a = 0.9 km
The distance from the far side of the park to Mark's house, c = 1.6 km
Whereby the included angle between lines, 'a' and 'c' is the ∠B = 85°, by cosine rule, we have;
b² = a² + c² - 2·a·c·cos(B)
Where;
b = The length of the park in kilometers
By plugging in the known values of 'a', 'b', and 'c', we get;
b² = 0.9² + 1.6² - 2 × 0.9 × 1.6 × cos(85°) ≈ 3.11899146089
∴ b = √(3.11899146089) ≈ 1.76606666377
Therefore, the length of the park, b ≈ 1.77 km.
Jasmine swims 12 laps every afternoon, Monday through Friday. How many laps does she swim in one week?
Answer:
60
Step-by-step explanation:
In one week, Jasmine swims on Monday, Tuesday, Wednesday, Thursday, and Friday. Meaning she swims 5 days a week. If she swims 12 laps on all 5 days, then she swims a total of 60 laps.
Find x. Use a simplified radical or round to the nearest tenth.
Pleas helpppp
Answer:
[tex]x = 7 \sqrt{2} [/tex]
Step-by-step explanation:
[tex]sinθ = \frac{opp}{hyp} [/tex]
[tex]sin45° = \frac{7}{x} [/tex]
[tex] \frac{ \sqrt{2} }{2} = \frac{7}{x} [/tex]
Cross multiply:
[tex]( \sqrt{2} )(x) = 7(2)[/tex]
[tex]x = \frac{14}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } [/tex]
[tex]x = \frac{14 \sqrt{2} }{2} [/tex]
[tex]x = 7 \sqrt{2} [/tex]
What is the value of x in the figure?
Step-by-step explanation:
If there are two straight lines the opposite angles equal each other
so 4x+2=150
subtract both sides by 2
4x=148
divide both sides by 4
x=37
Hope that helps :)
b. If 3x - 3 and 5x + 7° are the angle of a linear pair, find their measurement the angle
Answer:
x = 22°
the angles are: 63° and 117°
Step-by-step explanation:
a linear pair of angles total together to be 180°
so:
3x - 3 + 5x + 7 = 180
combune like terms:
8x = 176
divide both sides of the equation by 8:
x = 22°
the angles are: 63° and 117°

Let f(x) = 5x – 2 and g(x) = 2x + 3 and find f(x) –
Select the correct response:
f(x) – g(x) = 7x + 1
f(x) – g(x) = 3x – 5
f(x) – g(x) = 7x – 1
f(x) – g(x) = -3x + 5
Answer:
f(x) - g(x) = 3x - 5
Step-by-step explanation:
Hi,
To subtract f(x) and g(x), we need to do (5x - 2) - (2x + 3). We solve and we get 3x - 5. So, f(x) - g(x) = 3x - 5.
The second answer choice is correct.
I hope this helps :)

Answer this question to get marked as brainliest!!!!!
Answer:
113.14 is the answer use circle formula
find the surface area (will give brainliest)
Answer:
336 ft^2
Step-by-step explanation:
All you have to do is find the area of each face, and add them up.
Firstly lets starts with the identical triangles.
There are two of them, and the area of a triangle is b*h/2
So the area is 6*8/2 , which is 24, and since their are two of them, we add another 24, and we get 48 so far.
Since all the other sides are rectangles, we can just multiply the given lengths and add them up.
So, we have
12x10, which is 120,
12x8, which is 96, and
12x6, which is 72.
Now add all of them up.
48+120+96+72 which is 336
Your answer is 336 ft^2

[tex]given \: that \: p = {x}^{2} + 4x - 2 \: and \: q = 2x - 1 \: and \: q - p = 2 \: find \: x[/tex]
Answer:
x= -1
Step-by-step explanation:
p= x² +4x -2 -----(1)
q= 2x -1 ------(2)
q -p= 2 -----(3)
Substitute (1) and (2) into (3):
2x -1 -(x² +4x -2)= 2
2x -1 -x² -4x +2= 2 (Expand bracket)
-x² -2x +1=2 (Simplify)
x² +2x +2 -1= 0 (Bring all terms to one side)
x² +2x +1= 0
(x +1)²= 0 (Factorise)
x +1= 0 (Square root both sides)
x= -1 (-1 on both sides)

is the mean number of books between all the
students, rounded to the nearest tenth?
Answer:
8.7
Step-by-step explanation:
Add up all the books
5 students have 6 books each
3 students have 8 books each and so on
5 * 6 = 30
8*3 =24
9*6 = 54
12*4 = 48
-------------
156 books
Divide by the number of students
156/18 =8.6666666
Round to the nearest tenth
8.7
The average ( or mean) number of books per student is 8.7 books
