Answer:

A. -1.5 B.2

Step-by-step explanation:

The Axis of symmetry is the line that goes through the center of the parabola. And resembles a symmetrical shape that makes the parabola look the same on both sides.

In this case for A, -1.5 would be the answer because it is in the center of the parabola on the x-axis. For B, 2 is the axis of symmetry because it lines up in the center of the parabola.

Ymorist [56]

Answer:

Step-by-step explanation:

Given

17 % of the drivers stopped have invalid licenses

n=24 drivers are stopped

using Binomial distribution

^nC_r(p)^r(q)^{n-r}

here p=0.17

q=1-0.17=0.83

(a)none will have valid license i.e. r=0

P(r=0)^{24}C_0(0.17)^0(0.83)^{24}=(0.83)^{24}=0.0114

(b)Exactly one have invalid license i.e. r=1

P(r=1)=^{24}C_1(0.17)^1(0.83)^{23}=24\times 0.17\times (0.83)^{23}

=0.0561

(c)At least 2 will have invalid license i.e. r\geq 2

P(r\geq 2)=1-P(r=0)-P(r=1)

P(r\geq 2)=1-0.0114-0.0561

P(r\geq 2)=0.932
