let velocity of Max is v, and total time t

at 12 mins

distance of Victoria = 3•12•v= 36v

distance of Max = 12v

after 12 mins

distance of Victoria = (t-12)v/3

distance of Max = (t-12)v

since the race was a tie, then

total distance of Victoria = total distance of Max

36v + (t-12)v/3 = 12v + (t-12)v

cancel v from both sides

36 + t/3 - 4 = t

algebraic manipulation

⅔ t = 32

t = 48 mins

Keiko uses 6.9 pints of blue paint and white paint to paint her bedroom walls. 2/5 of this amount is blue paint, and the rest is

lianna [129]

Answer: $4.14\ \text{pints}$

Step-by-step explanation:

Given

Keiko uses 6.9 Pints of blue and white paint

If the fraction of blue paint is $\frac{2}{5}$ , then thr fraction of white paint is

$1-\dfrac{2}{5}=\dfrac{3}{5}$

Amount of white paint is

$\Rightarrow \dfrac{3}{5}\times 6.9=4.14\ \text{pints}$

Find the slope of the line through each pair of points (12, -18) & (-15, -18)

padilas [110]

Answer:

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(-18 + 18) / (-15 - 12)

0 / -27

= 0

So, the slope is 0.

a – 3b = 22 a = b – 2 What is the solution to the set of equations in the form (a, b)? (–10, –8) (–12, –10) (–8, –6) (–14, –12)

Vinil7 [7]

A = b - 2

a - 3b = 22
(b - 2) - 3b = 22
b - 2 - 3b = 22
-2 - 2b = 22
-2b = 24
-b = 12
b = -12

a = b - 2
a = -12 - 2
a = -14

Solution set {-14, -12}

The probability of being a universal donor is 6% (O-negative-blood type). Suppose that 6 people come to a blood drive.' a) What

Tcecarenko [31]

Answer:

$Mean = 0.36$

$SD = 0.5817$

$P(x=3) = 0.003588$

Step-by-step explanation:

Given

Let

A = Event of being a universal donor.

So:

$P(A) = 0.06$

$n = 6$

Solving (a): Mean and Standard deviation.

The mean is:

$Mean = np$

$Mean = 6 * 0.06$

$Mean = 0.36$

The standard deviation is:

$SD = \sqrt{np(1-p)}$

$SD = \sqrt{6*0.06*(1-0.06)}$

$SD = \sqrt{0.3384}$

$SD = 0.5817$

Solving (b): P(x = 3)

The event is a binomial event an dthe probability is calculated as:

$P(x) = ^nC_x * p^x * (1-p)^{n-x}$

So, we have:

$P(x=3) = ^6C_3 * 0.06^3 * (1-0.06)^{6-3}$

$P(x=3) = ^6C_3 * 0.06^3 * (1-0.06)^3$

$P(x=3) = 20 * 0.06^3 * (1-0.06)^3$

$P(x=3) = 0.003588$
