What graphs? there isnt a picture
Answer:
21
Step-by-step explanation:
Substitute.
We are given x = 3, y = 9 and z = 2
3(9-2) = 3(7) = 21
It’S 750-600 this the answer
We can calculate (62 + 90) / 2 = 76. it's <span>known that 95% lies between the mean and twice the standard deviation. </span><span>if the mean is "μ" and the standard deviation is "σ": </span><span>μ-2σ and μ+2σ. i</span><span>f μ=76, then </span><span>76+2σ = 90, so 2σ = 14, so σ = 7.
</span>
<span>the mean is 76 and the standard deviation 7. </span>
