At a stop sign, some drivers come to a full stop, some come to a rolling stop' (not a full stop, but slow down), and some do not

Natasha2012 [34]

Answer:

Option C.

Step-by-step explanation:

Given information:

Male-Full stop = 6, Male-Rolling stop = 16, Male-No stop = 4

Female-Full stop = 6, Female-Rolling stop = 15, Female-No stop = 3

Using the given information we get

Total number of males = 6 + 16 + 4 = 26

Total number of males = 6 + 15 + 3 = 24

Probability of No stop is

$p=\dfrac{\text{No-stop}}{Total}$

$p=\dfrac{4+3}{50}$

$p=\dfrac{7}{50}$

We need to find the number of males that would we expect to not stop at all.

Expected number of males = Number of males × Probability

Expected number of males = $26\times \dfrac{7}{50}$

Expected number of males = $3.64$

Therefore, the correct option is C.

Naily [24]

Answer: $550.00

Step-by-step explanation: Equation: I = Prt

<u>Calculation:</u>

First, converting R percent to r a decimal

r = R/100 = 2%/100 = 0.02 per year,

then, solving our equation

I = 5500 × 0.02 × 5 = 550

I = $ 550.00

The simple interest accumulated

on a principal of $ 5,500.00

at a rate of 2% per year

for 5 years is $ 550.00.

Hope this helped! ;)

denis-greek [22]

Answer:

$\boxed{\bold{y=-(x+6)^2+32}}$

Step-by-step explanation:

$y=-x^2-12x-4\\\\y=-(x^2+12x)-4\\\\y=-(\underline{x^2+2\cdot x\cdot6+6^2}-6^2)-4\\\\y=-\left[(x+6)^2-36\right]-4\\\\y=-(x+6)^2+36-4\\\\\bold{\underline{y=-(x+6)^2+32}}$
