Answer: 0.25

Step-by-step explanation:

The data we have is:

Slacks: one brown, one black.

Sweaters: one tan, one red, one white.

Shirts: one white, one gray.

If the clothes are selected at random, then the probability that Julie will wear brown slacks is equal to the number of brown slacks, divided the total number of slacks.

We have 1 brown slack and 2 slacks in total, so the probability is:

p1 = 1/2 = 0.5

We do the same for the white shirt, we have 2 shirts and one is white, so the probability is:

p2 = 1/2 = 0.5

And we do not have any condition in the sweater, so we can ignore that selection.

Then the probability of both events happening at the same time (that Julie will wear brown slacks and a white shirt) is equal to the product of the individual probabilities: P = p1*p2 = 0.5*0.5 = 0.25

kendra biked 10kilometers on monday .she biked twice as many kilometers on tuseday how many total meters did she bike
hram777 [196]

Answer:

10km+10km*2 = 30km

30km*(1000m/1km) = 30000m

In the second equation of the problem, the kilometers from the initial total distance biked is cancelled out by the conversion of kilometers to meters, as seen in the 1000m/1km (or 1000 meters for every 1 kilometer).

How do we find the factors of x2 – 64
sweet-ann [11.9K]

Answer:

The factors of x²-64 is equal to (x-8)(x+8).

Step-by-step explanation:

The given expression is:

x²-64

we know that, 8² = 64

So,

(x²-8²) = (x-8)(x+8) [As (a-b)(a+b) = a²-b²]

So, the factors of x²-64 i equal to (x-8)(x+8).

What is y=x+10 in Standard Form?<br><br> ASAP please, thanks!
Allushta [10]
The standard form is Ax + By = C

Given the linear equation, y = x + 10, we must transpose x to the left-hand side of the equation:

- x + y = x — x + 10

- x + y = 10

Next, we must multiply both sides by (-1) because A must be positive:

(-1) (- x + y) = 10 (-1)

This leads to:

x — y = -10 in standard form, Ax + By = C

PLZ HELP URGENT!!!! the statement "cot theta= 12/15, sec theta= -13/5 and the terminal point determined by theta is in quadrant
Reptile [31]
We know that
in the IV quadrant
cos theta is positive
and 
sin theta is negative
so
cot theta=cos theta/sin theta--------> cot theta must be negative
sec theta=1/cos theta------> sec theta must be positive

therefore

the answer is the option
<span>A. cannot be true because sec(theta) is greater than zero in quadrant 4</span>
