A number is chosen at random from 1 to 25. Find the probability of selecting an odd number or multiples of 5. *
Answer:
Odd number: 13/25 (52%)
Multiples of 5: 5/25 (20%)
Step-by-step explanation:
There are 13 odd numbers between 1 and 25 so you have a 13/25 chance which is 52% (13/25 = 0.52). There are 5 multiples of 2 between 1 and 25 so you have a 5/25 chance which is 20% (5/25 = 0.2).
The probability of selecting an odd number or multiples of 5 is 3/5
What is probability?"It is finding out the possibilities of the occurrence of an event."
Formula to find the probability of an event:"P(A) = n(A) / n(S)
where, n(A) is the number of favorable outcomes of an event A
n(S) is the total number of outcomes for an experiment"
For given question,
A number is chosen at random from 1 to 25.
n(S) = 25
Let event A: selecting odd number
⇒ A = {1 , 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25}
⇒ n(A) = 13
So, the probability of selecting odd number would be,
⇒ P(A) = n(A)/n(S)
⇒ P(A) = 13/25
Let event B: selecting a number which is multiple of 5
⇒ B ={5, 10, 15, 20, 25}
⇒ n(B) = 5
So, the probability of selecting a number which is multiple of 5 would be,
⇒ P(B) = n(B)/n(S)
⇒ P(B) = 5/25
Let (A ∩ B) represents the odd numbers which are multiple of 5
⇒ (A ∩ B) = {5, 15, 25}
⇒ n(A ∩ B) = 3
So, the probability of selecting odd numbers which are multiple of 5 would be,
⇒ P(A ∩ B) = n(A ∩ B)/n(S)
⇒ P(A ∩ B) = 3/25
So, the probability of selecting an odd number or multiples of 5 is,
⇒ P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
⇒ P(A ∪ B) = 13/25 + 5/25 - 3/25
⇒ P(A ∪ B) = 15/25
⇒ P(A ∪ B) = 3/5
Therefore, the probability of selecting an odd number or multiples of 5 is 3/5

85% of all teachers work in the summer. If you sample 6 random teachers, what is the probability they all work over the summer?
Answer:
[tex]\frac{5}{6}[/tex]
Step-by-step explanation:
Given parameters
Percentage of all teachers the works in summer = 85%
Number of teachers sampled = 6 teachers
Unknown:
The probability that they all work in summer = ?
Solution:
Now, to solve this problem, let us find the number of teachers that works in summer from the given size;
Number of teachers = 85% x 6 = 5.1;
Since it is not possible to have 5.1 people, the number of teachers will be 5
The probability = [tex]\frac{5}{6}[/tex]

Step-by-step explanation:
Negative numbers are worth way less than positive numbers. In order to solve, the biggest looking negative number is worth less.
Positive is bigger
Negative is smaller
*EXTRA*
negative plus negative = positive
negative plus positive = negative
negative times negative = positive
negative times positive = negative

A friend recently planned a camping trip. He had two flashlights, one that required a single 6-V battery and another that used two size-D batteries. He had previously packed two 6-V and four size-D batteries in his camper. Suppose the probability that any particular battery works is p and that batteries work or fail independently of one another. Our friend wants to take just one flashlight. For what values of p should he take the 6-V flashlight
Answer:
The values of p = 0 < p ≤ 2/3
Step-by-step explanation:
First we write the probability of 6V flashlight working representing it as a binomial mass function of a binomial random variable
P ( 6v flashlight working ) = P ( at least one 6V battery works )
= P ( 1 6v battery work ) + P ( 2 6v battery work )
= b( 2; 2, p ) + b( 1; 2, p )
write out a formula of b( 2; 2, p ) + b( 1; 2, p )
P ( 6v flashlight working ) = p^2 + 2p( 1 - p )
Next we write the probability of D flashlight working representing it as a binomial mass function of a binomial random variable
P ( D flashlight works ) = p ( at least two D batteries works )
= b( 4; 4, p ) + b(3;4, p ) + b(2; 4, p )
write out a formula of b( 4; 4, p ) + b(3;4, p ) + b(2; 4, p )
P ( D flashlight works ) = [tex]P^4 + 4p^3 ( 1- p ) + 6p^2 ( 1- p)^2[/tex]

The machine that Holley operates tightens 40 bolts every 3 minutes. The bolts are delivered to her machine station in boxes containing 1,000 bolts each. Which equation can be used to determine t, the number of minutes it takes Holley's machine to tighten a box of 1,000 bolts at the same tightening rate?
Answer:
75
Step-by-step explanation:
3 divide by 40= 0.0075
0.0075 times 1000= 75

The area
The area of a triangle ABC is 64 cm². Given AB = 11 cm and BC = 15 cm, Find ABC. Trying to find angle B.
Answer:
∠B ≈ 50.9°
Step-by-step explanation:
The area formula for a triangle can be used to find the missing angle.
Area formulaWe don't want confusion between A for area and angle A, so we define Q as the area of the triangle with sides a, c, and included angle B. In this scenario, 'a' represents side BC (opposite angle A), and 'c' represents side AB (opposite angle C).
Q = (1/2)ac·sin(B)
Unknown angleSolving for B, we have ...
2Q/(ac) = sin(B)
B = arcsin(2Q/(ac)
B = arcsin(2(64)/(11(15)) = arcsin(128/165)
∠B ≈ 50.9°

half of the substance to remain is called the half-life of the substance.
The half-life of a pesticide is 10 years. A farmer initially applies 200 grams of the
pesticide to a fence post.
Complete the following statements.
After 20 years, there are
grams of pesticide left. Round your answer
to the nearest whole gram.
After 60 years, there are
grams of pesticide left. Round your answer
to the nearest hundredth of a gram.
After
years, there are approximately 1.03 grams of pesticide
left. Round your answer to the nearest whole year.
Answer:
Instructions are below.
Step-by-step explanation:
To calculate the final amount of a given substance, we need to use the following formula:
final amount= initial amount / (2^n)
n= elapsed time / half-life
For 20 years:
n= 20/10= 2
Final amount= 200/(2^2)
Final amount= 50 grams
For 60 years:
n= 60/10= 6
Final amount= 200/ (2^6)
Final amount= 3.125 grams
To calculate the elapsed time it is more complicated:
elapsed time= ln(ending amount/beginning amount) / (-decay constant)
ln= natural logarithm
decay constant= ln(2) / half-life
decay constant= 0.0693
elapsed time= ln(1.03/200) / (-0.0693)
elapsed time= 76.028
Prove:
n= 76.02/10= 7.602
Final amount= 200/(2^7.602)= 1.03 grams

What is the circumference, in feet, of the circle. Round to the nearest tenth
Answer: 4.7 ft
Step-by-step explanation:
Since this is a diameter we are going to do the formula that uses the diameter to find the circumference.
C=3.14(d)
1.) Insert the numbers into the formula: C= 3.14*1.5
You’ll get 4.71 as your answer.
Next round to the nearest tenth and you’ll get 4.7.

7x - 2 = 9x+5
Please help!!
Answer:
x=-7/2
Step-by-step explanation:
Answer:
x = -7/2 or -3.5
Step-by-step explanation:
7x - 2 = 9x + 5
Add 2 to both sides
7x = 9x + 7
Subtract 9x from both sides
-2x = 7
Divide both sides by -2
x = -7/2
x = -3.5
What is -7 2/3 + (5 1/2) + 8 3/4 ?
Answer:
-72/3+51/2+83/2=89/4
Step-by-step explanation:
2x/5 + 5/8 = 1/4 help
[tex] \frac{2x}{5} + \frac{5}{8} = \frac{1}{4} [/tex]
[tex] \frac{2x}{5} = \frac{1}{4} - \frac{5}{8} [/tex]
[tex] \frac{2x}{5} = \frac{2}{8} - \frac{5}{8} [/tex]
[tex] \frac{2x}{5} = \frac{2 - 5}{8} [/tex]
[tex] \frac{2x}{5} = \frac{ - 3}{8} [/tex]
[tex]2x = \frac{ - 3}{8} \times 5[/tex]
[tex]2x = \frac{ - 15}{8} [/tex]
[tex]x = \frac{ - 15}{8} \div 2[/tex]
[tex] x = \frac{ - 15}{8} \times \frac{1}{2} [/tex]
[tex]x = - \frac{ 15}{16} [/tex]
(3x+5)(3x+9) express as a trinomial
Answer:
9x^2+42x+45
Step-by-step explanation:
Foil (3x+5)(3x+9) by taking the numbers in the left parenthesis and multiplying it by the numbers on the right. So 3x(3x), then 3x(9), then 5(3x) and 5(9). Now we have 9x^2 + 27x+15x+45, simplify to get 9x^2+42x+45.
In science class, Vicky did an experiment with an unknown solid. She started with 11 grams of the solid. During the experiment, the change in the mass of the solid was –4 grams. What was the final mass of the solid To solve the problem, Jamal subtracted 11–(–4) and came up with an answer of 15 grams. Is Jamal correct? Why or why not?
Step-by-step explanation:
In this following excerpt,
We know that jamal wants to know the final mass, for this to be solved. We have to add the initial mass (11) to the change in the mass i.e, [-4] for this to be qualified as the final mass we are supposed to add the 11 to the -4, i.e, (11+(-4).)
Answer:
All in all the statement to support this resolution is,
11 + (-4)
