Jake bakes and sell apple pies. he sells each pie for $5.75. the materials to make the pies cost $40. the boxes jake puts the pi

dezoksy [38]

Answer:

$18\ pies$

Step-by-step explanation:

Let

x-------> the number of pies

we know that

$5.75x-40-12.50=50$ -----> linear equation that represent the situation

solve for x

$5.75x-52.50=50$

$5.75x=50+52.50$

$5.75x=102.50$

$x=102.50/5.75=17.8$

Round to the nearest whole number

$17.8=18\ pies$

What is the equation of the following graph in vertex form? HELP PLS

sammy [17]

Answer:

y = (x - 2)^2 + 1

Step-by-step explanation:

The general equation of a parabola in vertex form is y-k = (x-h)^2. Here, we can see immediately from the graph that the vertex is at (2, 1). Thus, the equation of this particular parabola takes the form y - 1 = a(x - 2)^2. We must still determine the value of a. Note that the graph goes through (0, 5). Thus, 5 - 1 = a(0 - 2)^2, or

4 = 4a. Thus, a = 1, and the equation of this parabola is y - 1 = (x - 2)^2, or, after simplification, y = (x - 2)^2 + 1.

In a large population, 69 % of the people have been vaccinated. If 3 people are randomly selected, what is the probability that

andre [41]

Answer:

$P( X \geq 1)=1-P(X$

And the probability is:

$P(X=0) = (3C0) (0.69)^0 (1-0.69)^{3-0} = 0.0298$

And replacing we got:

$P( X \geq 1)=1-P(X$

Step-by-step explanation:

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=3, p=0.69)$
