Step-by-step explanation: desmos is a good online graphing calculator to graph y= 6x-16.5
120 - 36 as a product with the GCF as a factor. True, we can factor out the GCF and we'll have a product:
GCF(120,36) = GCF(5(24),36)=GCF(5(12)(2),12(3)) = 12
We can factor that out and get:
120 - 36 = 12(10 - 3) = 12(7)
Answer: TRUE
How to find the GCF of three numbers.
There are a couple different ways; the obvious way is to find the GCF of the first two and then then GCF of the result and the third.
The other way is to prime factorize all three numbers; for each prime factor count how many times it occurs in each input. In the GCF it will occur the minimum of those three. Multiply the resulting powers of prime factors to get the GCF.
GCF(60,90) = GCF(30(2), 30(3)) = 30
60 + 90 = 30(2 + 3)
Xiao missed a factor of ten in the GCF.
Answer:
a) 0.997 is the probability that the breaking strength is at least 772 newtons.
b) 0.974 is the probability that this material has a breaking strength of at least 772 but not more than 820
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 800 newtons
Standard Deviation, σ = 10 newtons
We are given that the distribution of breaking strength is a bell shaped distribution that is a normal distribution.
Formula:
a) P( breaking strength of at least 772 newtons)
Calculation the value from standard normal z table, we have,
0.997 is the probability that the breaking strength is at least 772 newtons.
b) P( breaking strength of at least 772 but not more than 820)
0.974 is the probability that this material has a breaking strength of at least 772 but not more than 820.
This is true because it is an unknown number so it is replaced by a variable.
