newton watches a movie with his friends. they watch 50% of the movie and then takes a break. they then watch the remaining 65 minutes = how long was the movie
Answer:
130 minutes
Step-by-step explanation:
They watched 50% of movie, means 50% left unwatched
Remaining length = 65 minutes = 50% of movie
Movie length = 65 *2 = 130 minutes

Question 20
Mr. Stakur rolls a 20-sided die ten times. He rolls were 1,2,3,3,4,6,7,7,8, and 11,
Find the experimental probability Find the experimental probability of Norris rolling at least 10,
Was this higher or lower than what should have theoretically happened?
А
10 percent, Lower
B
20 percent, Higher
С
20 percent, Lower
D
10 percent, Higher
The correct option regarding the probability of rolling a number that is at least 10 is given by:
А 10 percent, Lower
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For the theoretical probability, it is calculated before any experiment. 11 out of 20 numbers are at least 10, hence it is given by:
pT = 11/20 = 0.55 = 55%.
For the experimental probability, we consider previous trials, in which one out of 10 resulted in a number that is at least 10, hence:
pE = 1/10 = 0.1 = 10%.
Which is lower than the theoretical probability, hence option A is correct.

eeeeeehelpmeeeeeeeeeee value of x and y
Step-by-step explanation:
As we can see x and 70° is alternate with each other so it can be name as alternative angle ....
Alternative angle are always equal....So .....
x = 70° ( being alternative angle )
Now....we can see that y and x is vertically opposite ....so it can be name as vertically opposite angle....
y = x ( being vertically opposite angle )
y = 70°
20 points. brianliest if you get it right, and my appreciation
Answer:
x = 17
Step-by-step explanation:
75° and (4x + 7)° are alternate angles.
75 = 4x + 74x = 68x = 17A board is 86 inches long. How long is it in feet and inches?

please help what is the effect on the graph of the parent function f(x) = x when f(x) is replaced with 4f(x)
A function assigns the values. When in the function f(x)=x, f(x) is replaced by 4f(x), the slope of the function reduces by a factor of 4.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given the function f(x) is equal to x. If f(x) in the given function is replaced with 4f(x), then the result will be,
[tex]4f(x) = x\\\\f(x)=\dfrac{x}4 \\\\ f(x) = \dfrac14 \times x[/tex]
Hence, when in the function f(x)=x, f(x) is replaced by 4f(x), the slope of the function reduces by a factor of 4.

Find the horizontal and vertical shift of y=Sqrt x+2-3
Answer: Left 2, Down 3
Step-by-step explanation:
[tex]y=\sqrt{x+2}-3[/tex]
To find the horizontal shift, set the values under the root equal to 0
x + 2 = 0
x = -2
This means the functions is shifted left 2 units
To find the vertical shift, look at the -3
This means the graph is shifted down 3 units.

What is the value of x 2/3x+2=4
To solve for x, we can perform inverse operations to cancel values out.
For addition, we can do subtraction.For multiplication, we can do division.And vise versa.Eventually, we must isolate x to one side of the equal sign, or equation. That will give us its value.
Solving the Question[tex]\dfrac{2}{3}x+2=4[/tex]
⇒ First, isolate the x term by subtracting 2 from both sides:
[tex]\dfrac{2}{3}x=2[/tex]
⇒ Now, multiply both sides by 3 to get rid of the fraction:
[tex]2x=6[/tex]
⇒ Finally, divide both sides by 2 to isolate x:
[tex]x=3[/tex]
Answer[tex]x=3[/tex]
Answer:
x = 3
Step-by-step explanation:
[tex]\sf \dfrac{2}{3}x+2=4[/tex]
Subtract 2 from both sides.
[tex]\sf \dfrac{2}{3}x=4-2\\\\\sf \dfrac{2}{3}x=2[/tex]
Multiply both sides by 3.
[tex]\sf2x=2*3\\2x=6[/tex]
Divide both sides by 2.
[tex]\sf x=\dfrac{6}{2} \\\\\sf x=3[/tex]

Calculating the relative frequencies from the data given in the table. Choose all that correctly describe an association between favorite subject and grade.
A higher percentage of 8th graders than 7th graders prefer History.
A higher percentage of 7th graders than 8th graders prefer English.
A higher percentage of 8th graders than 7th graders prefer Math/Science.
The statement second a higher percentage of 7th graders than 8th graders prefer English and statement third a higher percentage of 8th graders than 7th graders prefer Math/Science are correct.
What is a conditional relative frequency?It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total frequency cell to total frequency.
We can find conditional relative frequency as:
For first cell:
= 38/116
= 0.327
= 32.75% (refer attached picture)
Similarly, we can find for other cells.
A higher percentage of 7th graders than 8th graders prefer English and History, while a higher percentage of 8th graders than 7th graders prefer Math/Science.
Thus, the statement second a higher percentage of 7th graders than 8th graders prefer English and statement third a higher percentage of 8th graders than 7th graders prefer Math/Science are correct.
