to estimate the speed of a car, v, in miles per hour, based on the length, L, in feet, of its skid marks when suddenly braking o

Leno4ka [110]

Answer:

69.6 miles per hour

Step-by-step explanation:

Length of the skid marks = 242 feet

The formula used for the velocity is

$v=2\sqrt{5L}$

where, L is the length of skid marks in feet and the velocity obtain has the units of miles per hour.

By substituting the value

$v=2\sqrt{5\times 242}$

v = 69.6 miles per hour

Thus, the speed of the car at the time of accident is 69.6 miles per hour.

Suppose a and b are mutually exclusive events, and that p(b)=0.48 and p(a or b)=0.98. find p(a).

olga2289 [7]

The value of p(a) is 0.5

Mutually exclusive events are those events that do not occur at the same time

Given,

The a and b are mutually exclusive events

P(a AND b)=0

P(a)=0.48

p(a or b)=0.98

We know that,

P(a or b)=P(a)+P(b)-P(a AND b)

P(a or b)=P(a)+P(b)-0

P(a or b)=P(a)+P(b)

P(a)=P(a or b)-P(b)

Substitute the given values

P(a)= 0.98-0.48

P(a)=0.5

Hence, the value of P(a) is 0.5

Jenny bought 7 t-shirts, one for each of her 7 brothers, for $9.95 each. The cashier charged her an additional $13.07 in sales t

maw [93]

It's simple, first you have to read the text, let's start.

She arrives with x

Jenny bought 7 T-shirts

x-7*price, so x-7*9.95

The cashier charged her an additional.

$x-7*9.95-13.07$

Then left for her 7.28

therefore

$x-7*9.95-13.07=7.28$

$x-69.65-13.07=7.28$

$x-82.72=7.28$

$x=7.28+82.72$

$\boxed{\boxed{x=\$90.00}}$

She started with $90.00
