Answer:

Briana saved $1.80.

Step-by-step explanation:

When the sales promotion is 20% off.

Cost price is $45

Amount after discount is = 45-(0.20\times45)=36 dollars

When the sales promotion is 10% off.

Cost price is $42

Amount after discount is = 42-(0.10\times42)=37.80 dollars

Hence, Briana saved 37.80-36=1.80 dollars

45x.20=9
42x.10=4.2
9-4.2=$4.80

You roll a pair of fair dice until you roll “doubles” (i.e., both dice are the same). what is the expected number, e[n], of roll
bonufazy [111]

We need to define our outcomes and events.

 

Finding the probability<span> of each event occurring separately, and then multiplying the probabilities is the step to <span>finding  the probability</span> of two independent events that occur in sequence.

</span>

<span>
To solve this problem, we take note of this:</span>

 

The roll of the two dice are denoted by the pair

(I, j) ∈ S={ (1, 1),(1, 2),..., (6,6) }

Each pair is an outcome. There are 36 pairs and each has probability 1/36. The event “doubles” is { (1, 1),(2, 2)(6, 6) } has probability p= 6/36 = 1/6. If we define ”doubles” as a successful roll, the number of rolls N until we observe doubles is a geometric (p) random variable and has expected value E[N] = 1/p = 6.

Someone please help ASAP will give brainliest

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0)

You need to find "m" and "b".


If you look at the graph, when x = 0, y is 1, so the y-intercept is 1.

y = mx + 1

To find "m", you can use the slope formula and find two points on the graph and plug it in, or you can use this:

slope=\frac{rise}{run}

Rise is the number of units you go up(+) or down(-)

Run is the number of units you go to the right.


If you look at the graph, from each point you go up 1 unit, and to the right 1 unit. So your slope is \frac{1}{1} or 1


y = 1x + 1

y = x + 1
