Answer:
p = 0.259264214
Step-by-step explanation:
26 - 7 = 19 with good brakes
Probability of picking 4 with good brakes
p = 19/26 * 18/25 * 17/24 * 16/23
p = 0.259264214
The probability that all the randomly chosen cars have good brakes is approximately 0.169 or 16.9%.
To calculate the probability that all the randomly chosen cars have good brakes, we need to consider the number of cars with good brakes and the total number of cars.
Total number of cars assembled: 26
Number of cars with bad brakes: 7
To calculate the probability, we can use the concept of combinations.
The number of ways to select 4 cars out of the remaining 26-7 = 19 cars with good brakes is given by the combination formula:
C(n, r) = n! / (r! * (n-r)!)
where n is the total number of cars with good brakes and r is the number of cars to be randomly selected.
In this case, n = 19 and r = 4.
The total number of ways to select 4 cars from the total pool of 26 cars is given by the combination formula:
C(26, 4) = 26! / (4! * (26-4)!)
Now, we calculate the probability that all the randomly chosen cars have good brakes:
Probability = (Number of favorable outcomes) / (Number of total outcomes)
Number of favorable outcomes = C(19, 4)
Number of total outcomes = C(26, 4)
Probability = C(19, 4) / C(26, 4)
Using a calculator, we can compute these combinations and evaluate the probability:
Probability ≈ 0.169
Therefore, the probability that all the randomly chosen cars have good brakes is approximately 0.169 or 16.9%.

What is the range of the function graphed below?
Answer:
[tex]-\infty < y < -2[/tex]
Step-by-step explanation:
Given
The attached graph
Required
The range of the graph
From the graph we can see that the curve points down towards the y-axis,
This means that y starts from a [tex]-\infty[/tex] number
Coming up, the curve stops increasing at 2 and becomes horizontal; This means that y ends at 2
Hence, the range is: [tex]-\infty < y < -2[/tex]

Answer:
-4/7 =n
Step-by-step explanation:
2/3 ( 1+n) = -1/2 n
Multiply each side by 6 to get rid of the fractions
6*2/3 ( 1+n) =6* -1/2 n
4(1+n) = -3n
Distribute
4+4n = -3n
Subtract 4n from each side
4+4n -4n = -3n -4n
4 = -7n
Divide each side by -7
4/ -7 = -7n/-7
-4/7 =n

If a student is selected at random find the probability the student is a senior given that it's a female round to the nearest whole percent
Answer:
16%
Step-by-step explanation:
It says to find the probability the student is a senior given that it's a Female. So let's see. There are 19 females in total, and we're trying to figure out the probability that one of them will be a senior. Well, there are 3 female seniors.
[tex]\frac{3}{19\\}[/tex]
Divide 3 by 19 (not 19÷3, 3÷19)
=.157894736etc
You'll get a continuous decimal, but that's ok. The directions say round to the nearest whole percent. That means the percent should end up with no decimals.
16% (not 15.7, round it up instead to 16%)
Therefore, the answer is 16%. Hope this helps! :)
The probability of the student is a senior and female is 16%
What is probability?Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favorable outcomes / Number of sample
It says to find the probability the student is a senior given that it's a Female. There are 19 females in total, and we're trying to figure out the probability that one of them will be a senior. Well, there are 3 female seniors.
The probability of the student being a senior and female is calculated as below:-
Divide 3 by 19 (not 19÷3, 3÷19)
Probability = 0.157894736 = 0.16
Probability = 0.16 x 100 = 16%
Therefore, the probability of the student is a senior and female is 16%

if two angles in a triangle are 60° and 30°, is the third angle acute, obtuse, or right?
Answer: Right Angle
Step-by-step explanation:
And Since The Angles Of a Trangle Add Up To 180° When You Substract 90 From It You Remain With Another 90° Which Means The Angle Is Non Other Than a right angle traingle
60° + 30° = 90°
180° - 90° = 90°
∴ 90° = Right Angle Traingle

Can anyone tell me what the answer to this problem is and the explination?
The figure shown above is triangle. The area of the triangle is a= 1/2base times height.
Base is 10 . The height is 6.
A= 1/2bh
A= 1/2*10*6
A= 1/2*60
A= 30
Or you can find the area of the triangle separately and add them up.
First triangle :
The half of the base is 10/2= 5
B= 5 H= 6
A= 1/2*6*5
A= 15
Second triangle :
b= 5
h= 6
a= 1/2*5*6
a= 15
Add up them both areas 15+15= 30
