Jane wrote the numbers 1-100 and placed them in a bag. If she selects a number without looking, what is the probability that the
Sloan [31]

Since she wrote the numbers 1-100, we know that the probability for one number is 1/100.

If she selects a number without looking, it's a 1/100 chance she'll pull out one specific number.

However, here we need to find the probability of a number below 5. There are four numbers below 5 from the range to 1-100 and they are 1, 2, 3, and 4.

Therefore, since there are 4 numbers below 5, we have a 4/100 chance of Jane pulling out a number below 5.

In simplified terms it would be \frac{1}{25}

In decimal form, it would be 0.04

Which of the following are solutions to 2x2 – 8x - 90? Select all that apply.
Bond [772]

Answer:

x=-5, x=9

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}

in this problem we have

2x^{2} -8x-90  

equate to zero

2x^{2} -8x-90=0  

so

2=-1\\b=-8\\c=-90

substitute in the formula

x=\frac{-(-8)\pm\sqrt{-8^{2}-4(2)(-90)}} {2(2)}

x=\frac{8\pm\sqrt{784}} {4}

x=\frac{8\pm28} {4}

x=\frac{8+28} {4}=9

x=\frac{8-28} {4}=-5

therefore

The solutions are x=-5, x=9
