The answer is 60.7 because 90-29.3=60.7
The probability that his number will be 4 is one in eleven, or 1/11.
Answer: 285.2 kg
Step-by-step explanation:
Given
The volume of helium in the balloon is 
The density of the helium is 
Mass of the helium gas is given by the product of density and volume
Thus, the mass of gas is 285.2 kg
About 4.01% of the test scores in the normal distribution that are greater than 90
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
Z score is given by:
z = (raw score - mean) / standard deviation
Given that mean score is 76, and the standard deviation is 8.
For x > 90:
z = (90 - 76) / 8 = 1.75
P(z > 1.75) = 1 - P(z < 1.75) = 1 - 0.9599 = 0.0401
About 4.01% of the test scores in the normal distribution that are greater than 90

Exponents can be expressed in terms of quotient or fraction.
For example: x^6 can be expressed as x^8 / x^2 = x^8-2 = x^6.
From the question, 5^8 can be expressed as
5^10/5^2 = 5^8
(5^2)(5^8) / (5^2) = 5^8
