Answer:
Kindly check explanation
Step-by-step explanation:
Total Number of pens = 5
Number of defective pens = 2
Number of non-defective pens = 3
A.) number of defective pens selected :
X : {0, 1, 2}
It is possible that no defective pen will be selected ; 1 defective will be chosen or both pens are defective.
2.)
Defective as Success (since selecting a defective pen is the point of interest.
3.)
Since selection is done without replacement
Probability of success per selection is different for each selection ;
Number of defective = 2
Number of observations = 5
P(success on first selection) = 2/5
P(success on second selection) = 1/4
Hence, X is not well approximated by a binomial random variable.
4.) if selection is done with replacement ; then then the probability of success per selection will be the Same for each selection made. Hence, X will be well approximated by a binomial Random variable.
5.) If sampling is done without replacement, then the the hypergeometric function will be a more effective approximation.
3. Find the value of x.

Answer:
x = -3
y = 4
Step-by-step explanation:
distribute first
7x + 35 = 2y + 6
combine 'like terms'
7x - 2y = -29
do same steps for second equation
4x + 4y = 13 + 3x
x + 4y = 13
System of Equations:
7x - 2y = -29
x + 4y = 13
Multiply the first equation by 2 to eliminate the 'y-term'
14x - 4y = -58 (Now add this to the second equation)
+ x + 4y = 13
15x = -45
x = -3
Substitute -3 for 'x' to find 'y'
-3 + 4y = 13
4y = 16
y = 4

Latoya's softball team won 75%, or 18, of its game. Define a variable. Write and solve an equations to determine the number of games the team played.
Will give brainliest
Answer:
18 / 3 * 4 = a
a = 24
Step-by-step explanation:
so we know that 18 is = to %75 but we need to know what %100 is, to figure this out lets find a common denominator
so we know that %75 of something is 3/4, and to double check, we can take the fraction 3/4 and divide it the way its written, bc thats what a fraction is, a small division problem
3 / 4 = 0.75 or 75/100 or %75
so now we know we have 3 out of 4 parts of something, to find out how big each part is, we divide the number (18) by how many pieces we have...
18 / 3 = 6
so each 1/4 is = to 6, now to figure out the whole, we multiply by how many pieces are in said whole, in this case by 4
6 * 4 = 24
so since we know that 6 is = to %25 and we multiplied 6 by 4, we can do the same to %25...
25 * 4 = 100
and have the whole
this is basically a detailed explanation of the other answer
hope this helps :)

A car manufacturer announced that next year the price of a certain model car would increase by 3.5%. This year the price is $15,649 . The increase in the price of the car is $? The new price of the car is $?
The increase will be the original price x the increase rate.
15649 x 0.035 = $547.72
The new price would be original price + increase
15649 + 547.72 = $16,196.72
Explain the difference between (-5)squared and -5squared.
Answer:
The major difference between square and rectangle is that a square has all its sides equal whereas a rectangle has its opposite sides equal. In Geometry, we have learnt different types of shapes such as square, rectangle, cube, cone, cylinder, parallelogram, rhombus, and so on.
All these shapes can fall under any one of the categories such as two-dimensional shapes or three-dimensional shapes. All the shapes can share a few characteristics. But they have many different characteristics properties that differentiate the shapes from each other. In this article, let us discuss the difference between a rectangle and a square in detail.

Stores often mark up items each year to cover inflation.
Last year, a CD at Juan's Tunes cost $12.95. This year,
the cost was marked up 8%. The store also gave anyone
who bought four CDs this
year a 10% discount. Explain
the steps to find the final cost for the four CDs this year.
Answer:
so you have $12.95. then you multiply it by 8% which gives you $13.986. Then you take 10% off of it, which gives you $12.5874.
Answer:
The new price would be 108% of last year’s price. Multiply the new price by 4 and then multiply that amount by 90% to find the sale price.

Apples and tangerines were sold in the ratio of 6 to 4.
40
tangerines were sold. How many fruits were sold?
Answer:
100.
Step-by-step explanation:
By proportion the number of apples sold is (6/4) * 40
= 6 *10
= 60.
Total fruit = 40 + 60 = 100.

Show mathematically why the ratio 15:10 is not equal to 10:15
Answer:
Hello here is my answer
Step-by-step explanation:
The 2 ratios are 15:10 and 10:15
multiply the numbers of the first ratio with the last number if the second ratio, which means,
15*15=225
10*15=150
we get 225:150
now we multiply the numbers of the second ratio with the last number if the first ratio.which means,
10*10=100
15*10= 150
now compare bot of them
225:150::100:150
we see that 225:150>100:150
hence proven that 15:10 is not equal to 10:15

y =
Answer:
y = -4
Step-by-step explanation:
given x = -1
6x - 7y = 22
6(-1) -7y = 22
-6 - 7y = 22
-7y = 22 + 6
-7y = 28
y = -4

The first side of a triangle is four inches longer than twice the
second side. The third side of the triangle is 5 inches shorter than
the sum of the other two sides. The perimeter is 72 inches. Find
the lengths of the three sides.
Answer:
1st Side: 27 inches, 2nd Side: 23/2, 3rd Side: 67/2
Step-by-step explanation:
Let's solve your problem step by step:
First side should be: 2x+4
Because 2 times the second side =, and 4 longer than that.
Second side should be: x
This is the base of the equation, since all the numbers depend on "x"
Third side should be: (3x+4)-5
Because x + x+4, and the third side is 5 shorter..
We add all and we get 72.
Solve for x.
x=23/2
Now, we can solve for other sides, by doubling it and adding 4.

Please select the best answer from the choices provided
T
F
Answer: False
Step-by-step explanation:
Economic equilibrium simply refers to a scenario where the economic forces are equal and balanced. It is the condition whereby the demand and the supply of goods and services are equal.
We should note that economic equilibrium is only theoretical. In reality, this isn't true as the market doesn't reach equilibrium, Eben though it moves towards it.
Therefore, the statement in the question is false.

if the cube was Rolled 78 x and the nine appears 26 times what was the experimental probability of rolling a 9
Answer:
1/3 = 0.3333 = 33.33% experimental probability of rolling a 9.
Step-by-step explanation:
The experimental probability is given by the number of desired outcomes divided by the number of total outcomes, after a number of experiments is made.
In this question:
Cube rolled 78 times.
9 appeared 26 times
26/78 = 1/3 = 0.3333 = 33.33% experimental probability of rolling a 9.

Determine the no. of permutations
for the word PHOTOGRAPH
Given:
The word is "PHOTOGRAPH".
To find:
The no. of permutations for the given words.
Solution:
The total number of letters in the word PHOTOGRAPH is 10.
It is clear that P, H, O are twice and T, G, R, A are occurred once.
To find the total number of permutations, we need to divide the permutation of 10 letters by the permutation of repeated letters.
The total number of permutations for the given word is
[tex]Permutations=\dfrac{10!}{2!2!2!1!1!1!1!}[/tex]
[tex]Permutations=\dfrac{10\times 9\times 8\times 7\times 6\times 5\times 4\times 3\times 2\times 1}{2\times 2\times 2}[/tex]
[tex]Permutations=10\times 9\times 7\times 6\times 5\times 4\times 3\times 2\times 1[/tex]
[tex]Permutations=453600[/tex]
Therefore, the no. of permutations for the word PHOTOGRAPH is 453600.

Help this is trigonometry I think 35 points!!
Answer:
y = 16.3
Step-by-step explanation:
We would apply the formula for altitude of a right triangle which is given as:
h = √(xy)
Where,
h = 14
x = 12
y = y = ?
Plug in the values
14 = √(12*y)
14² = (√(12*y) (squaring both sides)
196 = 12*y
196/12 = 12y/12 (division property of equality)
16.3 = y (nearest tenth)
y = 16.3
