For a charity event, raffle tickets are printed such that they have a vowel (excluding y) as the first character and a prime number less than 10 as the second digit. (Note that 1 is not a prime number.) The probability that the winning ticket has the vowel contained in the word event and the digit is the number of letters in the word event is
Answer:
P=5%
Step-by-step explanation:
In order to solve this problem, we can use the following formula for the probability of two independent events:
P(A and B)=P(A)*P(B)
so we need to find the probability for each event to happen.
They are asking for the probability that the winning ticket will have the letter e on it. There are 5 vowels in the alphabet (a, e, i, o and u). Therefore the probability for the first letter to be e is:
[tex]P(A)=\frac{desired}{total}[/tex]
[tex]P(A)=\rac{1}{5}[/tex]
We also know there are 4 prime numbers between 0 and 10 (2, 3, 5, 7) so the probability for the number to be a 5 is:
[tex]P(B)=\frac{1}{4}[/tex]
so the probability of getting a ticket that starts with an e and ends with a 5 is:
P(A and B)=P(A)*P(B)
[tex]P(A and B)=(\frac{1}{5})(\frac{1}{4})[/tex]
[tex]P(A and B)=\frac{1}{20}[/tex]
so the probability is 5%
The probability that the winning ticket has the vowel contained in the word event and the digit is the number of letters in the word event is P=5%.
What is probability?The chance of happening an event out of all the possible outcomes is called the probability of an event.
The probability of two independent events
P(A and B)=P(A)*P(B)
The probability that the winning ticket will have the letter e on it. There are 5 vowels in the alphabet (a, e, i, o and u). So, the probability for the first letter to be e is:
P(e) =1/5
There are 4 prime numbers between 0 and 10 (2, 3, 5, 7) so the probability for the number to be a 5 is:
P(B) =1/4
So, the probability of getting a ticket that starts with an e and ending with a 5 is:
P(A and B)=P(A)*P(B)
= 1/5 x 1/4 =1/20
In percentage , probability is 1/20 x 100 % =5%
Hence, the probability is 5%

find the slope of the line passing through (3,7 ) and (6,11) asap
Answer:
4/3
Step-by-step explanation:
You're going to want to use the slope formula which is attached. Using this, you'll take the second y and subtract the first y from it. In other words, 11-7, which is 4. This will be the numerator. Then, you'll take the second x and subtract the first x from it. In other words, 6-3, which is 3. This will be the denominator. The final answer is [tex]\frac{4}{3}[/tex].

The height of a pebble dropped from a cliff 20,00 feet heigh is described by formula h(t)=20,000 + 5t^2. How long will the pebble take to reach a height of 32,500 feet?
Answer:
It will take 50 seconds for the pebble to reach the height
Step-by-step explanation:
To calculate the time, simple substitute h(t) for 32,500
So we have
32,500 = 20,000 + 5t^2
5t^2 = 32,500-20,000
5t^2 = 12500
t^2 = 12500/5
t^2 = 2500
t = square root of 2500
t = 50 seconds

What is an expression?An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
here, we have,
given expression is,
f(x) = -4x^2 + 4x - 4
now, we have to find the value of f(3).
so, we have to put x = 3, in the expression.
we get,
f(x) = -4x^2 + 4x - 4
f(3) = -4* 9 + 4*3 -4
or, f(3) = -36 + 12 -4
or, f(3) = -28
Hence, The solution is the value of f(3) = -28.

Which statement accurately describes the vector shown?
Answer:
magnitude of √61 and a direction angle equal to approximately 40°
Step-by-step explanation:
I inserted the x,y axis into a vector calculator to get the magnitude and angle :D
The magnitude of the vector is √61 and the direction of the angle is 40 degrees option (C) magnitude of √61 and a direction angle equal to approximately 40° is correct.
What is a vector?It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.
We have a vector shown in the picture.
The coordinate of the vector are:
The tail coordinate = (0, 0)
The head coordinate = (6, 5)
We can find the magnitude of the vector using the distance formula:
The distance formula can be given as:
[tex]\rm M=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]\rm M=\sqrt{(6-0)^2+(5-0)^2}[/tex]
M = √61
The direction of the angle:
tanA = 5/6
tanA = 0.8333
A =39.80 ≈ 40 degrees
Thus, the magnitude of the vector is √61 and the direction of the angle is 40 degrees option (C) magnitude of √61 and a direction angle equal to approximately 40° is correct.

Rendering math...While solving an equation, Wayra made some mistakes. Her solution is given below. Please help her to identify the step in which there is a mistake and also the right solution. Step 1: 13(z+6) = 4(z-3)-5z Step 2: 13z+19 = 4z-12-5z Step 3: 13z+19 = z-12 Step 4: 13z+z = -19-12 Step 5: 14z =-31 Step 6: z =-3114 Wayra has made a mistake at?
Answer:
According to the calculation, Wayra mage a mistahe in step 2 where she added 13 and 6 together instead of multiplying to get 78.
She also make a mistake in step 2 where he subtracted 5z from 4z to get z instead of -z
Step-by-step explanation:
Given the equation solved by Wayra expressed as;
Step 1: 13(z+6) = 4(z-3)-5z
She is find the value of z from the equation;
Step 2: Open the parenthesis using the distributive property;
13(z+6) = 4(z-3)-5z
13z + 13(6) = 4z - 4(3) - 5z
13z + 78 = 4z - 12 - 5z
Step 3: Simplify
13z + 78 = 4z - 5z - 12
13z + 78 = -z -12
Step 4: Collect the like terms;
13z + z = -12 - 78
Step 5: Simplify the result
14z = -90
Step 6: Divide both sides by 14
14z/14 = -90/14
z = 6.428
According to the calculation, Wayra mage a mistahe in step 2 where she added 13 and 6 together instead of multiplying to get 78.
She also make a mistake in step 2 where he subtracted 5z from 4z to get z instead of -z
