Ascience class has 5 girls and 5 boys in the seventh grade and 3 girls and 5 boys in the eighth grade. the teacher randomly selects a seventh grader and an eighth grader from the class for a competition. what is the probability that the students she selects are both boys? write your answer as a fraction in simplest form.

Probability would be to select both  boys.

Step-by-step explanation:

To find the probability of picking two boys, we need to first know how many different ways she can pick the 7th and 8th grader.

There are 10 (5 girls and 5 boys) 7th-graders and 8 (3 girls and 5 boys) 8th-graders. So the total number of ways she can pick is:

10  ×  8  =  80

To select two boys, there are 5 boys in the 7th-grade class and 5 in the 8th-grade class, so there are:

5  ×  5  =  25  ways

Which gives us the probability of:

=

Probability would be to select both  boys.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
