Answer:
give brainliest please I need it to level up
Step-by-step explanation:
Let one of the numbers be x,
Then the two numbers are x and x +1
And,
x+x+1 = 53
2x = 53 - 1 (Transposing 1 from LHS to RHS)
2x = 52
x = 52/2
x = 26
x + 1 = 27
So, The two numbers are 26 and 27.
Answer:
30 bracelets
Step-by-step explanation:
she could make 6 in 1 hour so 18 bracelets in 3 hours plus 12 bracelets in 2 hours which equals 30 bracelets.
6(3+2)=x
x=30
Uhhh that doesn’t seem possible but then again i forgot simple math lol
Answer:
I don't know about this thing
Answer:
The mean is 9.65 ohms and the standard deviation is 0.2742 ohms.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
10% of all resistors having a resistance exceeding 10.634 ohms
This means that when X = 10.634, Z has a pvalue of 1-0.1 = 0.9. So when X = 10.634, Z = 1.28.




5% having a resistance smaller than 9.7565 ohms.
This means that when X = 9.7565, Z has a pvalue of 0.05. So when X = 9.7565, Z = -1.96.




We also have that:

So





The mean is

The mean is 9.65 ohms and the standard deviation is 0.2742 ohms.
