Answer:
Greatest prime factor of is 7.
Step-by-step explanation:
Given that
Two positive integers are and
.
(1) Greatest Common Factor or <em>HCF</em> of and
is 5.
(2) Least Common Multiple or <em>LCM </em>of and
is 105.
To find:
The greatest prime factor of the product = ?
Solution:
First of all, let us learn about a property of HCF and LCM of two numbers.
The product of two numbers and
is equal to the product of their HCF and LCM.
Using this property for the given numbers:
Now, let us make prime factors of to find the greatest of the prime factors.
So, the prime factors of are 5, 5, 3 and 7.
Greatest prime factor of is 7.
The average number of skateboards produced per day last year is 310.
<h3>What is a normal distribution?</h3>It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.
We have:
The standard deviation of skateboards produced was 20 skateboards. They found they produced up to 280 skateboards on 93.32% of the days last year.
Z- score at 93.32% is -1.5
We know:
μ = 280 + 30
μ = 310
Thus, the average number of skateboards produced per day last year is 310.
