Answer:
a: b: c= 2: 9 :4
Step-by-step explanation:
Since b is the common variable in both fractions, ensure that the value of b in both fractions are the same. Here, the value of b in both fractions are 9. Thus, we can find their relationship with one another in terms of ratio by combining the two fractions together.
a: b: c= 2: 9: 4
This ratio is already in it's simplest form.
Answer:
B.) Yes; it can be rotated 180° or less and match the original figure.
Step-by-step explanation:
You have to trust me its b I did the quiz on Pearson Conexus. I would show a picture but I'm on pc and don't know how to .
My answer will help.
Anyways, have a great day/night !! <3
Answer:
7.
Step-by-step explanation:
Place value can be defined as the numerical value representing a digit owing to its position in a number. Some examples of the various place values used in representing each digit are tenths, hundredths, thousandths, unit, tens, hundreds, thousands etc.
For example, in the number 0.27845;
- The place value of 0 is units.
- The place value of 2 is tenths.
- The place value of 7 is hundredths.
- The place value of 8 is thousandths.
- The place value of 4 is ten thousandths.
- The place value of 5 is hundred thousandths.
Therefore, given the number 0.27845.
The digit representing hundredths in 0.27845 is 7.
Answer:
A) 0.0107
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Mean of 440 seconds and a standard deviation of 40 seconds.
This means that
Find the probability that a randomly selected boy in secondary school can run the mile in less than 348 seconds.
This is the p-value of Z when X = 348. So
has a p-value of 0.0107, and thus, the correct answer is given by option A.
