Assume that 20 percent of students have taken calculus in high school. Of those who have taken calculus in high school, 80 perce

Alex73 [517]

Answer:

The probability that a randomly selected student plans to major in science is 40%

Step-by-step explanation:

Students who take calculus in high school = 20% or 0.2

Of these students, 80% or 0.8 plan to major in science.

That means of these students,

(100 -80) = 20% or 0.2 do not plan to major in science

Students who do not take calculus in high school = (100 -20)= 80% or 0.8

Of these students, 30% or 0.3 plan to major in science.

That means of these students,

(100 -30) = 70% or 0.7 do not plan to major in science.

The probability of students who take calculus in high school and plan to major in science = 0.2 * 0.8

= 0.16

= 16%

The probability of students who take calculus in high school and do not plan to major in science = 0.2 * 0.2

= 0.04

= 4%

The probability of students who do not take calculus in high school and plan to major in science = 0.8 * 0.3

= 0.24

= 24%

The probability of students who do not take calculus in high school and do not plan to major in science

= 0.8 * 0.7

= 0.56

= 56%

All of these probabilities will give 100% of the population.

(16+4+24+56)% = 100%

Therefore, the probability that a randomly selected student plans to major in science = 16% + 24%

= 40%

At Sunrise Donuts you can buy 6 donuts and 2 kolaches for $8.84. One kolache and 4 donuts would cost $5.36. What is the price of

Lelechka [254]

Set up a system of equations like this, where "k" represents a kolache and "d" represents a donut:

$\left \{ {{6d +2k = 8.84} \atop {k+4d = 5.36}} \right.$

We're solving for d. First, we can rearrange the second equation to have it equal k:

$k + 4d = 5.36$
$k = 5.36 - 4d$

Next, we can substitute this in for k in the first equation:

$6d + 2k = 8.84$
$6d + 2(5.36 - 4d) = 8.84$
$6d + 10.72 - 8d = 8.84$

Finally, we can get the value of d if we solve this equation:

$-2d + 10.72 = 8.84$
$-2d= -1.88$
$d = 0.94$

You can buy a donut at Sunrise Donuts for $0.94.
