Answer:
The first step is to determine the largest number that evenly divides the numerator and the denominator (also called the Greatest Common Factor of these numbers). In other words, what's the biggest number that goes into '2' (the numerator) and '4', the denominator?
Step 2. Once you've answered step 1 and realized that, for our fraction at least, the greatest number that evenly divides 2 and 4 is '2'. Now divide the top and the bottom by 2 to get your simplified fraction which is ½.
I hope this helps if you have any questions on my answer plz let me know Ty :3
Answer: In ∆ KLM above, NO // ML and < KNO = < KON. Find m < MNL =
Step-by-step explanation: dUNNO
Answer:
The root is x = -2
Step-by-step explanation:
1. Add 4 on both sides.
x^2 + 4r + 4 = 0
2. What two numbers, if added together and multiplied together, give 4?
2 and 2.
3. Factor
(x+2)(x+2)=0
4. Solve
x = -2 (There is only one root for this quadratic equation.)
Please give me brainliest is this is right. Than you!
Answer:
The standard deviation for the number of defective parts in the sample is 1.88.
Step-by-step explanation:
The sample is with replacement, which means that the trials are independent, and thus, the binomial probability distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
68 defective out of 400:
This means that 
From the shipment you take a random sample of 25.
This means that 
Standard deviation for the number of defective parts in the sample:
The standard deviation for the number of defective parts in the sample is 1.88.
Answer:
Answer:
44 = 12 + M
Step-by-step explanation:
Start with your final amount that everything else is going to equal
44 =
Then, add the $12 that is already saved to the other side\
44 = 12
But, that equation is not true yet, so we have to add the amount of money that she still needs to save
44 = 12 + M
That equation shows that the money she has saved ($12), plus the amount she still has to save will equal the amount she needs.
