If you have a TI calculator, then you can type in invnorm(1 - 0.628) You are subtracting the probability from 1 because the invnorm function finds the z-score given the probability to the left of the z-score

The correct answer is:

1.03

Explanation:

We will use a z-table to do this.

84.85% = 84.85/100 = 0.8485; this is the value we look for in the middle of the table. Once we find it, we see the number to the left is 1.00; above it we have 0.03. This means that 1.00+0.03 = 1.03 is the z-score for this value.

vector u is represented by the directed line segment RS and vector v is represented by the directed line segment OP. if R=(8,-2)

melamori03 [73]

The given points are

R=(8,-2) , S=(11,-6), O=(-3,-9), and P=(0,-13)

To find the value of u and v, we have to perform subtraction of the points . That is

$u= RS = =$

$v = OP = =$

Since we get the same values of u and v , therefore the two vectors are equal .

irinina [24]

For
ax+by=c
the slope is -a/b
20x+25y≥200
slope=-20/25=-4/5
negative slope

yint is where x=0
20(0)+25y≥200
25y≥200
y≥98
positive yint

x+y<10
slope=-1/1=-1
yint is where x=0
y<10
yint is at y=10

since it is equal, it is solid line
to tell if it is above then sub (0,0) and see if true
0≥200
false
shade on side that doesn't have (0,0), shade above line

x+y<10 doesn't have equal under so it is dashed
test (0,0)
0<10
true, it is shaded below

test point (4,5)

20(4)+25(5)≥200
80+125≥200
225≥200
true

4+5<10
9<10
true

so the ones that are true are

The line x + y < 10 has a negative slope and a positive y-intercept.
The line representing 20x + 25y ≥ 200 is solid and the graph is shaded above the line.
The overlapping region contains the point (4, 5).
