Find the probability of having 2, 3, or 4

denis-greek [22]

Answer:

16% for 2 successes, 6.4% for 3 successes, 2.6% for 4 successes, and 1% for 5 successes

Step-by-step explanation:

Since the success rate of a binomial experiment is 40%, converted to 0.4, you get the equation of f(x) = (0.4)^x, for where x is the amount of successful experiments

For the success of 2 experiments:

f(2) = (0.4)^2

=0.16 => 16%

For the success of 3 experiments:

f(3) = (0.4)^3

= 0.064 => 6.4%

For the success of 4 experiments:

f(4) = (0.4)^4

= 0.0256 => 2.56% => ~2.6

For the success of 5 experiments:

f(5) = (0.4)^5

= 0.01024 => 1.024% => ~1%

Find an equation for the line below.<br><br><br> will give brainiest

pogonyaev

Answer: $y=-\frac{x}{2}-6.5$

Step-by-step explanation:

First find slope m. From observing the equation we can see that there are two points on the line. They are (-5,-4) and (-1,-6). Using the formula to find slope rise/run we get m = -0.5.

Now we use the point-slope formula to start the switch to the slope-intercept formula. Using (-1,-6) as our x and y values and switching m=-0.5 we get y + 6 = -0.5 ( x + 1). Simplify and we get y + 6 = -x/2 - -0.5. Subtract 6 from both sides and the final equation is y = -x/2 - 6.5.

A florist sold 50 bouquets yesterday, including 10 rose bouquets. What is the experimental probability that the next bouquet sol

AlexFokin [52]

Answer:

$\frac{1}{5}$

Step-by-step explanation:

Given

Total number of bouquets sold yesterday $= 50$

Total number of rose bouquets sold yesterday $= 10$

Then the probability of selling a rose bouquet out of total 50 bouquet is

$\frac{10}{50} \\\frac{1}{5}$

Probability of selling other than rose bouquet out of total 50 bouquet is

$1 -$ probability of selling a rose bouquet

Substituting the given values in above equation we get -

$1 - \frac{1}{5} \\= \frac{4}{5}$

Probability that the next bouquet sold will be a rose bouquet

$1 * \frac{1}{5} \\\frac{1}{5}$

Emilia lost $4,000 in personal belongings due to a flood at her apartment complex. Fortunately, she had renter’s insurance with

docker41 [41]

She would receive $3500 maximum.

Since she has $10,000 in coverage, the entire $4000 loss is covered. However, the insurance company would only pay her the amount after the deductible has been taken:

4000 - 500 = 3500
