Answer:
z=1.96
Step-by-step explanation:
Using normal distribution table or technology, 97.5% corresponds to z=1.959964, generally denoted z=1.96, or 1.96 standard deviations above the mean.
(above value obtained from R)
Answer:
6 feet
Step-by-step explanation:
1/2 times 4 1/4
change to improper fractions
(3/2)*(17/4)
(3*17)/(2*4)=51/8=6 3/8 feet tall
3/8 of 12 inches is (3/8)*12=36/8=4 4/8=4.5 inches
Jebb is 6 feet 4.5 inches tall
Answer:
x + 5y = 7 or y = -⅕x + 1⅖
Step-by-step explanation:
First, find the rate of change [slope]:
-y₁ + y₂\-x₁ + x₂ = m
Then use the Point-Slope Formula since we are given points. Now, according to this formula, all negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY careful inserting the coordinates into the formula with their CORRECT signs. It does not matter which one you choose:
y - y₁ = m(x - x₁)
y - 1 = -⅕(x - 2)
y - 1 = -⅕x + ⅖
+ 1 + 1
_______________
y = -⅕x + 1⅖ >> Line in <em>Slope-Intercept</em><em> </em><em>Form</em>
If you want it in Standard Form:
y = -⅕x + 1⅖
+⅕x +⅕x
___________
⅕x + y = 1⅖ [We do not want fractions in our Standard Equations, so multiply by the denominator to get rid of it.]
5[⅕x + y = 1⅖]
x + 5y = 7 >> Line in <em>Standard Form</em>
__________________________________________________________
y - 2 = -⅕(x + 3)
y - 2 = -⅕x - ⅗
+ 2 + 2
______________
y = -⅕x + 1⅖
y = -⅕x + 1⅖
+⅕x +⅕x
___________
⅕x + y = 1⅖ [We do not want fractions in our Standard Equations, so multiply by the denominator to get rid of it.]
5[⅕x + y = 1⅖]
x + 5y = 7 >> Line in <em>Standard Form</em>
** You see? I told you that it would not matter which ordered pair you choose because you will always get the exact same result!!!
I am joyous to assist you anytime.
Answer:
C) y = 2x - 3 and y = -2x - 1.
Hope this helps you!
