One dozen students each drop a brass tack six times from a height of six inches onto a level hard surface. They record the number of times the tack lands point up. The table below lists their results.
a table of values
What was the experimental probability that the tack lands point-up for student 7?
0.800
0.833
0.200
Answer:
0.833
Step-by-step explanation:
1. locate which vertical column of the graph we are referring to:
student 72. calculate the total number of trials student 7 did:
if in 5 trials the tack landed point-up, and in 1 trial the tack did not land point-up, the total number of trials is 65 + 1 = 63. refer back to the question:
the question states: "what is the experimental probability that the tack lands point-up"4. interpret the graph:
of the 6 trials student 7 underwent, the graph tells us that 5 landed point-up. therefore the experimental probability of a tack landing point up is 5/6 (in 5 out of the 6 trials, the tack landed point-up)5. converting from fraction to decimal:
all the given answers are given in decimal form, whilst our current answer (5/6) is in fraction form. to convert to decimal form, simply divide the top number by the bottom number5 ÷ 6 = 0.833therefore, the experimental probability that the tack will land point-up, is 0.833

Given an expression [tex][(1.3)^{3} /{(1.2)^{2}}^{4} ]^{-6}[/tex].
We are required to find the equivalent expression of the given expression.
Expression is combination of numbers, fraction,symbols, coefficients, determinants, indeterminants or algebraic operations. It shows some relationship also. It is found without equal to form.
Expression is [tex][(1.3)^{3} /{(1.2)^{2}}^{4} ]^{-6}[/tex]
It is in fraction as we know that fraction is combination of two numbers one is numerator and denominator.
First we need to multiply the powers present in numerator and denominator.
=[tex](1.3)^{-18} /[{(1.2)^{2}}^{-24} ][/tex]
We have to invert the numerator and denominator because the powers in negative.
=[tex][(1.2)^{2}]^{24} /(1.3)^{18}[/tex]
Hence the equivalent expression for [tex][(1.3)^{3} /{(1.2)^{2}}^{4} ]^{-6}[/tex]is [tex][(1.2)^{2}] ^{24}/(1.3)^{18}[/tex].

How are the pieces of a step function related to the domain of the function? Justify your thinking.
Step-by-step explanation:
As we know, for any function domain is referred to as the set of input values that can be taken for an independent variable in the given function. Range of a function is defined as the set of output values generated for the domain (input values) of the function. In the case of a step function, for each value of x, f(x) takes the value of the greatest integer, less than or equal to x. For example:
[-2.19] = -3
[3.67] = 3
[-0.83] = -1
The domain of this function is a group of real numbers that are divided into intervals such as [-5, 3), [-4, 2), [-3, 1), [-2, 0) and so on. This explains the domain and range relations of a step function.
This can be generalized as given below:
[x] = -2, -2 ≤ x < -1
[x] = -1, -1 ≤ x < 0
[x] = 0, 0 ≤ x < 1
[x] = 1, 1 ≤ x < 2

Answer:
184m^2
Step-by-step explanation:
Ok first we will look at the triangles.
The formula for triangles is 1/2bh
The base in our triangle is 6, and the height is 4. Also, we have 2 such triangles.
so, we need to plug in our values into our formula, and multiply it by 2, since there are 2 triangles.
2( 1 / 2 ( 6 ) ( 4 ) )
2 ( 12 )
24.
The area of the 2 triangles is 24.
Now, the next part is gonna be hard to explain, but I promise the final answer is right.
lets find the area of the rectangle in the middle. That's easy, 6*10 = 60.
Because the top rectangle would connect to the 5m side of the triangle, then the area of the rectangle would be 10*5 = 50
The same thing applies to the bottom rectangle, so its also 50.
24+50+50+60 = 184
The unit is meters(m)
So, 184 m^2
The surface area of the prism based on the net provided will be 184 square meters.
What is the surface area of a triangular prism?Let h be the height and b be the base of the triangle.
Let L₁, L₂, and L₃ be the length and W be the width of the rectangle.
Then the surface area of the triangular prism will be
Surface area = 2 Area of triangle + 3 Area of rectangle
Surface area = h x b + (L₁ + L₂ + L₃) x W
From the figure, the length of the rectangles will be 5 m, 6 m, and 5m, and the width is 10 m.
From the figure, the height is 4 m and the base is 6 m of the triangle. Then we have
Surface area = 4 x 6 + (6 + 5 + 5) x 10
Surface area = 24 + 16 x 10
Surface area = 24 + 160
Surface area = 184 square m
The surface area of the prism based on the net provided will be 184 square meters.

Ben is picking cherries to make jam. each cherry weighs about 1/2 ounce. There are 16 ounces in a pound. He needs 3 pounds of cherries. About how many cherries does he need to pick?
Answer:
96 Cherries
Step-by-step explanation:
This is a question on some unit conversions.
First we convert 3 pounds to ounces.
Given 16 ounces = 1 pound,
3 pounds = 3 x 16 ounces = 48 ounces
Next, we will find the number of cherries required.
Number of Cherries required = Total weight of cherries needed (in ounces) / Weight per cherry.
= [tex]\frac{48}{0.5}[/tex]
= 48 * 2
= 96 cherries

Step-by-step explanation:
When you are writing a similarity statement, you must put the letters of both triangles in the same order. In other words, you must make the first letter of the first triangle match with the first letter of the second triangle, and so on.
In this figure, [tex]\angle K\cong\angle E[/tex], [tex]\angle L\cong\angle T[/tex], and [tex]\angle KUL\cong\angle EUT[/tex]. Hence,
[tex]\triangle KLU \sim \triangle ETU[/tex]
Since K is first, E is also first, as ∠K matches to ∠E. Since L is second, T is also second, as ∠L matches to angle ∠T.
Solve the equation r = 1/(x-1) for x in terms of r. In other words, manipulate the equation until you have x equal to an expression with r's in it but no x's.
Answer:
[tex]x=\frac{1}{r} +1[/tex]
Step-by-step explanation:
[tex]r=\frac{1}{x-1}[/tex]
[tex]r(x-1)=1[/tex]
[tex]x-1=\frac{1}{r}[/tex]
[tex]x=\frac{1}{r} +1[/tex]
Answer:
[tex]x=\dfrac{1+r}{r}[/tex]
Step-by-step explanation:
Given equation:
[tex]r=\dfrac{1}{(x-1)}[/tex]
Multiply both sides by (x - 1):
[tex]\implies r(x-1)=\dfrac{1}{(x-1)} \cdot (x-1)[/tex]
[tex]\implies r(x-1)=1[/tex]
Expand the brackets:
[tex]\implies rx-r=1[/tex]
Add r to both sides:
[tex]\implies rx-r+r=1+r[/tex]
[tex]\implies rx=1+r[/tex]
Divide both sides by r:
[tex]\implies \dfrac{rx}{r}=\dfrac{1+r}{r}[/tex]
[tex]\implies x=\dfrac{1+r}{r}[/tex]
help i forgot how to do this and this is one of the last questions on my summer homework
Answer:
162°
Step-by-step explanation:
They are on a straight line so add to 180
8x + 10 + 2x - 20 = 180
10x - 10 = 180
10x = 190
x = 19
We want AXB so 8x + 10 where x = 19
8(19) + 10 = 162 so it is 162°
Answer:
162 degrees
Step-by-step explanation:
These two angles add up to 180.
8x + 10 + 2x - 20 =180 Next combine the x terms and the constant terms
10x -10 = 180 Next Add 10 to both sides
10x = 190 D Next divide both sides by 10
x = 19. Now that we know x, we can solve for <AXB
8x + 10
8(19) + 10
152 + 10 = 162
