Answer:
Step-by-step explanation:
<u>Given function:</u>
<u>x-coordinate of the vertex is:</u>
<u>The axis of symmetry is the vertical line that passes through the vertex:</u>
- x = -3 is the line we need
Answer:
Solution given:
slope(m)=½
passing through point (x',y')=(0,3)
now
equation of a line is:
y-y'=m(x-x')
y-3=½(x-0)
y=½x+3
<u>D</u><u>.</u><u>y</u><u>=</u><u>½</u><u>x</u><u>+</u><u>3</u><u> </u><u>is</u><u> </u><u>a</u><u> </u><u>required</u><u> </u><u>equation</u><u> </u><u>of</u><u> </u><u>a</u><u> </u><u>line</u><u>.</u>
Given:
Population mean, μ = 10
Population standard deviation, σ = 1.5
Random variable, x = 11.
By definition, the z-score is
z = (x - μ)/σ
= (11 - 10)/1.5
= 0.667
Answer: 0.667
Answer:
C: (1,3)
Step-by-step explanation:
If we count 1 to the right on the x-axis and count 3 up on the y-axis, we will end up at the point of intersection which is (1,3).
Answer:
- 39
Step-by-step explanation:
x + 7= (-2)^5
x + 7 = -32
x = - 32- 7
x = - 39
