Answers
Answer:
see below
Step-by-step explanation:
The experimental probability is what you actually rolled
24/60 = 2/5 = 40%
The theoretical probability is what we expect to happen
=number of even numbers / total number of numbers
3/6 = 1/2 = 50%

Logan is doing a handstand dive from a 12 meter platform. The equation that models the path of her dive is given by LaTeX: h=-4.9t^2+12h = − 4.9 t 2 + 12, where t is seconds. After how many seconds will Logan hit the water?
Answers
Answer:
Time, t = 2.44 seconds
Step-by-step explanation:
Logan is doing a handstand dive from a 12 meter platform. The equation that models the path of her dive is given by :
[tex]h=-4.9t^2+12t[/tex]
It is required to find the time after which Logan will hit the ground. At this point, h = 0
[tex]-4.9t^2+12t=0\\\\t(-4.9t+12)=0\\\\t=\dfrac{12}{4.9}\\\\t=2.44\ s[/tex]
So, after 2.44 seconds it will hit the water.

a secant and tangent are drawn to a circle from a common exterior point. If the length is 14 inches and the length of the external segment of the secant is 4 inches, then it which of the following is the length,in inches, of the internal segment of the secant?
Answers
Answer:
Correct option: (3) 45
Step-by-step explanation:
Let's call the length of the tangent 'T', the length of the external segment 'E' and the length of the internal segment 'A'.
If we have a secant and a tangent to a circle, we can use the following property:
T^2 = E * (A + E)
If the tangent is 14 inches and the external segment is 4 inches, we have that:
14^2 = 4 * (A + 4)
196 = 4A + 16
4A = 180
A = 45
Correct option: (3)

The sum of angles in a triangle is 180°. Therefore,
x - 11 + 48 + 90 = 180
x + 127 = 180
x = 53°
Answer:
x = 53
Step-by-step explanation:
Using the information that angles in a triangle add up to 180°, we can set up and equation to find the value of x
⇒ Use the information that angles in a triangle add up to 180°, form an equation
→ x - 11 + 48 + 90 = 180
⇒ Simplify
→ x + 127 = 180
⇒ Minus 127 from both sides to isolate x
→ x = 53
We can substitute the value of x back into x - 11 + 48 + 90 = 180 to see if our value of x is correct, if we end up on 180 on both sides then the value of x is correct
→ x - 11 + 48 + 90 = 180
⇒ Substitute in the value of x
→ 53 - 11 + 48 + 90 = 180
⇒ Simplify
→ 180 = 180
This means that x = 53 is correct

Ms. Ziolkowski asks her class to write the correct trigonometric function for the triangle shown below.
Two students get into an argument about the correct answer.
Rhianna states that the correct trig function is tan A = 3/4. Christopher insists that the correct trig function is tan C = 4/3. Who is correct? In writing your response, be sure to include the terms opposite side, adjacent side, tangent ratio, and reference angle. Be sure to restate the question and explain your position with at least four sentences.
Answers
Answer:
They are both correct
Step-by-step explanation:
tan A = opposite / adjacent = 3/4 >>> A= 36.9 deg
tan C = opposite / adjacent = 4/3 >>> C= 53.1 deg
cheak:
<B+ <A + <C = 180 deg
90 + 36.9 + 53.1 = 180
180 = 180
Answer:
Botn are correct
Step-by-step explanation:
Tan ratio can be obtained by opposite/adjacent
Both students are correct. They have different values only because they have taken different reference angles
Rhianna has taken angle A as the reference angle,
So tanA = opposite/adjacent = BC/AB
tanA = 3/4
Christopher has taken angle C as the reference angle,
So tanC = opposite/adjacent = AB/BC
tanC = 4/3
What is the volume of the cylinder below? Use 3.14 for pi and I round to the nearest tenth
Answers
Answer:
Option (4).
Step-by-step explanation:
Formula to calculate the volume of a cylinder is,
V = πr²h
Here r = radius of the cylinder
h = Height of the cylinder
From the figure attached,
r = [tex]\frac{13}{2}=6.5[/tex] cm
h = 11 cm
Now we substitute the values of h and r in the formula,
V = π(6.5)²(11)
= 464.75π
= 1459.32
≈ 1459.3 cm³
Therefore, volume of the given cylinder is 1459.3 cm³
Option (4) will be the answer.
Pedro withdrew some money from his bank account. After giving $15 to his cousin, he spent 1/5 of what was left on a lamp, then he used the remaining $128 to buy a calculator. What percent of Pedro’s money did he give to his cousin?
*Please Show Work*
Answers
Answer:
He gave 8.57 % of his money for his cousin.
Step-by-step explanation:
In order to calculate the percent that Pedro gave to his cousin, we first need to calculate his total amount, which is given by "x". This is given by:
x = 15 + (x - 15)/5 + 128
x = 15 + x/5 - 3 + 128
x = x/5 + 140
x - x/5 = 140
(5*x - x)/5 = 140
4*x = 700
x = 175
He had originally $175 and gave $15 to his cousing, therefore we can use a rule of three to calculate the percent that he gave to his cousin:
$175 -> 100%
$15 -> y%
175*y = 1500
y = 1500 / 175
y = 8.57 %

In April, Phillipa rode 13 . 5 + 8 . 7 + 11 . 1 miles on her bicycle. In March, she rode ( 13 . 5 + 8 . 7 + 11 . 1 ) ÷ 2 miles, and in May, she rode 4 × ( 13 . 5 + 8 . 7 + 11 . 1 ) miles. Determine the month when she rode the most and the month when she rode the least. How many times farther did she ride in the month when she rode the most than in the month when she rode the least?
Answers
Answer:
Phillipa rode the most in May and rode the least in March.
Distance travelled by Phillipa on her cycle in May = 8 × Distance travelled by Phillipa on her cycle in March
Step-by-step explanation:
Given:
In April, Phillipa rode 13 . 5 + 8 . 7 + 11 . 1 miles on her bicycle. In March, she rode ( 13 . 5 + 8 . 7 + 11 . 1 ) ÷ 2 miles, and in May, she rode 4 × ( 13 . 5 + 8 . 7 + 11 . 1 ) miles.
To find: the month when she rode the most and the month when she rode the least
Solution:
Distance travelled by Phillipa on her cycle in April = 13 . 5 + 8 . 7 + 11 . 1 = 65 + 56 + 11 = 132 miles
Distance travelled by Phillipa on her cycle in March = ( 13 . 5 + 8 . 7 + 11 . 1 ) ÷ 2 = [tex]\frac{132}{2}=66[/tex] miles
Distance travelled by Phillipa on her cycle in May = 4 × ( 13 . 5 + 8 . 7 + 11 . 1 ) = 4 × 132 = 528 miles
So, she rode the most in May and rode the least in March
Distance travelled by Phillipa on her cycle in May = 8 × Distance travelled by Phillipa on her cycle in March

What is the image point of (3,8) after a translation right 4 units and up 1 unit?
Answers
Answer:
its going to be (7,9)
Step-by-step explanation:
Answer:
The image of the point after the translation would land the point at (7, 9).
Step-by-step explanation:
When you're moving a point right, imagine adding the number of units you are going right to the x value. When you're moving a point up, imagine adding the number of units you are going up to the y value.
(3 + 4, 8 + 1)
(7, 9)
So, the image of the point of (3, 8) after a translation right 4 units and up 1 unit is going to be (7, 9).

Given the definitions of f(x) and g(x) below, find the value of g(f(-1)).
f(x) = -4x – 7
g(x) = x² + 7x – 2
Answers
Answer:
(x)=(x-7)(x-4)
g(x)=x(2)+7x - 2
Now find a common denominator. (x+10)(x-4) is a good one.
x-16/(x+10)(x-4)+x-4/(x+10)(x-4)
2x-20/(x+10)(x-4)
The value of function g(f(-1)) is -70.
What is Function?
A relation between a set of inputs having one output each is called a function.
Given that;
The value of functions,
f (x) = -4x - 7
g (x) = x² + 7x - 2
Now, Value of function g(f(-1)) as;
g(f(x)) = g(-4x - 7)
= (-4x - 7)² + 7(-4x - 7) - 2
= (4x + 7)² + 7 × -4 × x - 7 × 7 - 2
= 16x² + 49 + 56x + 28x - 49 - 2
= 16x² + 84x - 2
Thus, g(f(x)) = 16x² + 84x - 2
Now, To find value of g(f(-1)) we can substitute x = -1,
g(f(-1)) = 16(-1)² + 84(-1) - 2
= 16 - 84 -2
= -70
Thus, The value of function g(f(-1)) is -70.

What is the slope-intercept equation of the line below?
Answers
Answer:
The slope-intercept form:
[tex]y = -3x +4[/tex]
Step-by-step explanation:
-To get the slope-intercept equation, you first need to find the slope by using this equation [tex]m = \frac{rise}{run}[/tex] (starting counting from the first point, to the second point) in order to get the slope. After you have the slope, you need to find the y-intercept ( y-intercept is where the line crosses the y axis of the graph, basically). So, to find that, you need look for the point that only crosses the y axis to get the y-intercept. After you have both the slope and y-intercept, you put it in slope-intercept form:
The two points I found from the following graph are:
[tex]( 1, 1)[/tex] and [tex](2, -2)[/tex]
Trick: Since the line of the graph shows that it is down (not up), Start counting down from point [tex]( 1, 1)[/tex] to point [tex](2, -2)[/tex]. Then, find the y-intercept:
[tex]m = \frac{-3}{1} = -3[/tex]
[tex]b = 4[/tex]
Use it to create a slope-intercept form:
[tex]y = mx +b[/tex] (where [tex]m[/tex] represents the slope and [tex]b[/tex] represents the y-intercept)
[tex]y = -3x +4[/tex]
So, therefore the slope-intercept form is [tex]y = -3x +4[/tex] .
