Answer:
Amy should not use her previous luck of rolling a 3 four times because theoretical probability remains the same even after an event favoring one side has occurred by chance.
Step-by-step explanation:
Assuming that this number cube has 6 sides, there is only 1 side that has a 3 on it. For this reason, every time the cube is rolled there is a 1 in 6 chance that the number will be a 3. If she rolls the number cube 240 times, 1 out of 6 rolls would be a 3. This means that 240/6 equals the number of times she would get a 3. Moreover, Amy would role the number 3 on 40 different times after rolling the cube for a total of 240.

Which expression is equivalent to t2 – 36?
Group of answer choices
(t – 12)(t + 3)
(t – 6)(t – 6)
(t + 6)(t – 6)
(t – 12)(t – 3)
Answer:
(t + 6)(t - 6)
Step-by-step explanation:
(t - 6)(t + 6)
(t . t) + (t . (6) + ((-6) . t) + ((-6) . 6)
= t² - 6t + 6t - 36
= t² - 36
so,
t² - 36 = (t + 6)(t - 6)

Find the length of the third side. If necessary, write in simplest radical form. sdquare root of 58 8
Answer:
√122
Step-by-step explanation:
Find the length of the third side. If necessary, write in simplest radical form. square root of 58 8
let the given sides be;
Hypotenuse = x
Adjacent = √58
Opposite = 8
Using pythagoras theorem;
hyp^2 = opp^2 + adj^2
x^2 = (√58)^2+8^2
x^2 = 58 + 64
x^2 = 122
x = √122
Hence the length of the unknown side is √122

There are 100 cookies and 80 brownies on a dessert table at a restaurant. Of these desserts, 12 cookies and 24 brownies contain nuts. What percentage of these desserts contain nuts?
Answer:
20%
Step-by-step explanation:
Total number of desserts: 100 + 80 = 180
Number of desserts that contain nuts: 12 + 24 = 36
What percentage is 36 of 180?
To find what percentage a part is of the whole, divide the part by the whole and multiply by 100%.
percent = 36/180 * 100% = 0.2 * 100% = 20%
Answer: 20%
A container can hold three orange slices. If a company had twenty-six orange slices to put into containers, how many more slices would they need to fill up the last container?
Answer:
The last container needs one more slice to be filled up.
Step-by-step explanation:
From the question, we know that only 3 oranges can fit into a container.
However, the company has 26 oranges that need to be inside containers.
We can find out the number of containers that will be filled up completely and the remainder left.
We will do this by dividing the number of orange slices available by the number that can fit into a container.
This is 26 / 3 = 8 remainder 2
Therefore, 8 containers will be filled up, with only two oranges left in the last container.
Remember that each container needs up to 3 oranges to be filled up. Since the last container has only 2 orange slices in it, it needs one more slice to be filled up.

What is Law of Cosines?The Law of Cosines is a mathematical formula used to find an unknown side or angle of a triangle, given the lengths of the other two sides and the angle opposite the unknown side. It is also known as the Cosine Rule.
The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite side c, the following equation is true:
c² = a² + b² - 2ab cos(C)
where cos(C) is the cosine of angle C. This formula can be rearranged to solve for any of the variables, depending on which values are known.
Given data ,
Let the triangle be represented as ΔXYZ
And , the measures of the sides of the triangle are
z = 75 inches
x = 26 inches
And , the measure of ∠Y = 135°
We can use the Law of Cosines to find the length of y, since we know two sides and the included angle of the triangle.
The Law of Cosines states that:
c² = a² + b² - 2ab cos(C)
where c is the side opposite angle C, and a and b are the other two sides.
In this case, we want to find the length of side y, which is opposite angle Y. So we can write:
y² = x² + z² - 2xz cos(Y)
Substituting in the given values, we get:
y² = 26² + 75² + 2(26)(75) cos(135°)
Simplifying, we get:
y² = 676 + 5625 - 2925√2
y² ≈ 9163
Taking the square root of both sides, we get:
y ≈ 95.76
Rounding to the nearest inch, we get:
y ≈ 96 inches
Hence , the length of y, to the nearest inch, is 96 inches

A line has a slope of 6 and passes through the point (1,4). What is its equation in
slope-Intercept form?
Write your answer using Integers, proper fractions, and improper fractions in simplest form.
y-x-O
The slope intercept form of the line that passes through the point (1, 4) and has the slope 6 is y = 6 x - 2.
The point that the line passes through is:
(1, 4)
The slope of the line is:
m = 6
The slope intercept form of the line is:
y - y₁ = m (x - x₁)
Substitute the values in the equation, we get that:
y - 4 = 6 ( x - 1)
y - 4 = 6 x - 6
y = 6 x - 6 + 4
y = 6 x - 2
Therefore, we get that, the slope intercept form of the line that passes through the point (1, 4) and has the slope 6 is y = 6 x - 2.

In ΔFGH, the measure of ∠H=90°, GH = 3.8 feet, and FG = 8.5 feet. Find the measure of ∠F to the nearest degree.
Answer:
F=26.555≈27 degrees
Step-by-step explanation:
sin F = opposite/hypotenuse = 3.8/8.5
sin F = 3.8/8.5
F = sin^-1(3.8/8.5)
(3.8 is opposite of angle F, 8.5 is hypotenuse)

Find f(-5) if f(x) = 5x + 11.
A) 4
B) 5
C) 6
Step-by-step explanation: Since f(x) = 5x + 11, we find f(-5)
by substituting a -5 in for the x in the function to get f(-5) = 5(-5) + 11.
Now just simplify the right side to get -25 + 11 or -14.
So f(-5) = -14.
