We have to determine the number which is rounded to the nearest tenth in the expression 0.304 1.325.
So, let us divide 0.304 by 1.325.
So, we get = 0.229
Now, we have to round the number 0.229 to the nearest tenth.
The tenths place is to the right of the decimal. Now, we will consider the digit at hundredths place which is '2', which is less than 5.
Therefore, the number rounded to the nearest tenth is 0.2.
Answer:
1. option B is correct i.e.,
2. option D is correct i.e., .
3. option B is correct i.e., .
Step-by-step explanation:
1. Since the given equation is:
As we know that
So, the given equation can be represented as:
2. Given equation is:
As we know that
so the given equation can be represented as:
.
3. Given equation is:
by using the properties ,
and
=
=
=
=
= .
which is option B.
Answer:
0.7486 = 74.86% observations would be less than 5.79
Step-by-step explanation:
I suppose there was a small typing mistake, so i am going to use the distribution as N (5.43,0.54)
Problems of normally distributed samples can be 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.
The general format of the normal distribution is:
N(mean, standard deviation)
Which means that:
What proportion of observations would be less than 5.79?
This is the pvalue of Z when X = 5.79. So
has a pvalue of 0.7486
0.7486 = 74.86% observations would be less than 5.79
