in a 400 page manuscript, there are 200 randomly distributed misprints if a page is selected, find the probability that it has 1 misprint
please show work
Answer:
½
Step-by-step explanation:
The probabliliry of picking a misprint is gotten by dividing the number of misprints by the total number of pages in the manuscript.
There are 200 randomly placed misprints in the 400 page manuscript.
Therefore, the probability of picking a misprint is:
200 / 400 = ½

What is distributive property of 7(5b +8)
Answer:
35b+56
Step-by-step explanation:
First, split the equation.
To do this, take 5b and 8, and make each of those their own little parentheses. Those would both be multiplied by 7.
7(5b) + 7(8)
Multiply out.
35b + 56
A particular type of cell increases by 75% in number every hour. Find the number of cells present at the end of 12 hours if there are initially 4 of these cells?
We have been given that a particular type of cell increases by 75% in number every hour. We are asked to find the number of cells present at the end of 12 hours if there are initially 4 of these cells.
We will use exponential growth formula to solve our given problem.
[tex]y=a\cdot (1+r)^x[/tex], where,
y = Final amount,
a = Initial amount,
r = Growth rate in decimal form,
x = Time.
[tex]75\%=\frac{75}{100}=0.75[/tex]
Upon substituting initial value [tex]a=4[/tex] and [tex]x=12[/tex] in above formula, we will get:
[tex]y=4\cdot (1+0.75)^{12}[/tex]
[tex]y=4\cdot (1.75)^{12}[/tex]
[tex]y=4\cdot 825.0050068497657776[/tex]
[tex]y=3300.020027[/tex]
[tex]y\approx 3300[/tex]
Therefore, there will be approximately 3300 cells at the end of 12 hours.

Answer:
-The measure of [tex]\angle A[/tex] :
[tex]\angle A = 144\textdegree[/tex]
-The measure of [tex]\angle B[/tex] (if needed):
[tex]\angle B = 144\textdegree[/tex]
Step-by-step explanation:
-Set the measure of [tex]\angle A[/tex] on one side and set the measure of [tex]\angle B[/tex] on the other side and it will be written as:
[tex]10x + 24 = 6x + 72[/tex]
-Then, solve for [tex]x[/tex] :
[tex]10x + 24 = 6x + 72[/tex]
[tex]10x + 24 - 6x = 6x - 6x + 72[/tex]
[tex]4x + 24 = 72[/tex]
[tex]4x + 24 - 24 = 72 - 24[/tex]
[tex]4x = 48[/tex]
[tex]\frac{4x}{4} = \frac{48}{4}[/tex]
[tex]x = 12[/tex]
-After you have found the value of [tex]x[/tex], plug in both the measure of [tex]\angle A[/tex] and [tex]\angle B[/tex] in order to get the actual angle measurement of [tex]\angle A[/tex] and [tex]\angle B[/tex] :
Finding the measure of [tex]\angle A[/tex] :
[tex]\angle A = 10(12) + 24[/tex]
[tex]\angle A = 120 + 24[/tex]
[tex]\angle A = 144\textdegree[/tex]
Finding the measure of [tex]\angle B[/tex] :
[tex]\angle B = 6(12) + 72[/tex]
[tex]\angle B = 72 + 72[/tex]
[tex]\angle B = 144\textdegree[/tex]
-Notice: That reason why both [tex]\angle A[/tex] and [tex]\angle B[/tex] have the same measurements, its because they are Alternate Exterior Angles, based on the diagram shown.
Given angle 1 and angle 2 are supplements, angle 3 and angle 4 are supplements, angle 1 is congruent to angle 4. Prove Angle 2 is congruent angle 3
m<1 + m<2 = 180°
m<3 + m<4 = 180°
Because they are both equal to 180°, you can set them equal to each other.
m<1 + m<2 = m<3 + m<4
Angles 1 and 4 are congruent (equal), so we can subtract them from each side to get:
m<2 = m<3

The volume of the following figure is 240in² Which of the following is the missing side length?
Answer:
8 in
Step-by-step explanation:
The formula to find the volume of a rectangular prism is l · w · h.
l = ?
w = 6 in
h = 5 in
We know the volume of the following figure is equal to 240 and so we can set up an equation where we solve for l (length).
l · 6 · 5 = 240
To get l by itself, you divide 240 by 6 and then by 5 to get your answer.
l = 8
We can check our work here by multiplying 8 · 6 · 5 which gives us the correct 240.

What is the value of y?
A. 630
B. 126°
C. 73°
D. 54°
Answer:
y = 63
Step-by-step explanation:
The sum of the angles of a triangle is 180
54+y+y = 180
Combine like terms
2y+54 = 180
Subtract 54 from each side
2y+54-54= 180-54
2y =126
Divide each side by 2
2y/2 = 126/2
y =63
Answer:
A. 63 degrees
Step-by-step explanation:
All angles added together would equal 180. We have two angles that equal y and a third that has 54. Our first step:
180-54=126
Both of the y angles equal 126. We want a separate value though, so we divide this by two.
126/2=63
Thus, A is our answer
A bag of potatoes weights 30 lb. If 74% of a potato is water, how many pounds of water are there in the bag?
Answer: There are 22.2 pounds of water in the bag.
Step-by-step explanation:
Hi, to answer this question we simply have to multiply the total weight of the bag by the water percentage in decimal form (divided by 100).
Mathematically speaking:
30 x (74/100) = 30 x 0.74 =22.2 pounds
There are 22.2 pounds of water in the bag.

Answer:
71
Step-by-step explanation:
its an isosceles triangle, as we can tell from the sides, that means that 2 angles are the same size as well. a triangle has 180 degrees.
180-38=142
142/2=71
check
71+71+38=180
that means x=71 degrees
hope this helps!!
Answer:
x = 71
Step-by-step explanation:
The triangle has 2 congruent sides and is isosceles.
Thus the 2 base angles are congruent, so
x = [tex]\frac{180-38}{2}[/tex] = [tex]\frac{142}{2}[/tex] = 71

the integers are x and x+2
x^2 + x^2 + 4x + 4 = 202
2x^2 + 4x -198 = 0

Select the grid that represents the ratio 3/5. Then find a percent equivalent to the given ratio. We
Answer:
60%
Step-by-step explanation:
I'm not sure about the grid (as you didn't attach any images), but I can help with the percentage part. To convert a fraction into a percentage, all you have to do is multiply the fraction by 100. When we do this, we get 3/5*100 = 60%.
Another way to think about it is to rewrite 3/5 so that it's denominaor is 100. We can mutiply the fraction by 20/20 which gives us 60/100. Note that this doesn't change the original fraction because 20/20 is equal to 1. Then, you simply take the numerator as the percentage. In this case, the numerator is 60, so the percentage will be 60%.

write a rule for the nth term of the sequence for which a3=27 and r=3
Answer:
These two things should help you with your question.
Step-by-step explanation:
How To Find The nth Term Of A Geometric Sequence
Written by Hazmo in Geometric Sequence
The nth term is one of the most important element of geometric sequence.
It’s usually used to find out specific values within the geometric sequences.
We calculate the nth term by first finding the common ratio ‘r’ by dividing any two consecutive terms of the sequence.
And then we substitute ‘a‘ with the first term of the sequence and ‘n’ with the term number to get the final answer of the nth term.
The general formula to find the nth term is:
an=a1r(n–1)
Understanding the nth term of a geometric sequence gets easier if we know the meaning of this term and variables used.
Therefore, let’s first find what the nth term is and then move on to the details of it’s evaluation with different examples.
The rule that is generated is 3, 9, 27, ........ an.
What is geometric progression ?"Geometric Progression (GP) is a type of sequence where each succeeding term is produced by multiplying each preceding term by a fixed number, which is called a common ratio. This progression is also known as a geometric sequence of numbers that follow a pattern."
Given,
a3 = 27
and r = 3
Formula for nth term is given by
[tex]a_{n} = a_{1}r^{n-1}[/tex]
so, we have
[tex]27 = a1.3^2[/tex]
so a1 = 3
Hence, the series becomes 3, 9, 27, ........an
