Answer:

2/5.

Step-by-step explanation:

The prime numbers from 1 to 20 are 2, 3, 5, 7, 11, 13, 17 and 19.

A total of 8.

So the probability of rolling a prime number is 8/20

= 2/5.

A piece of wire 6 cm long weighs 30 grams. What is the weight of an 8 m length of the same wire?
Feliz [49]

Answer:

4000 gm

Step-by-step explanation:

We can use ratios to solve

Change 8 m to cm

8m * 100cm/1m = 800 cm

6 cm             800 cm

-------------  = ------------

30 grams      x gm

Using cross products

6 * x = 800 * 30

6x = 24000

Divide by 6

6x/6 = 24000/6

x = 4000 gm

Given the parent function f(x)=x^2 in red, write the equation for the transformed function g(x) in green.
Nataly_w [17]

Answer:

g(x) = 2x² + 1

Step-by-step explanation:

The parabola got thinner, so to show that, you put a 2 <u><em>before</em></u> x²<em> </em>to show that the graph was <em>dilated </em>(or thinned) by a factor of <em>2 </em>(Note: this number can also be <em>negative</em>, so if the dilation factor is negative, it's okay). Since the parabola shifts up by <em>1</em>, you then add + 1<em> </em><em><u>after</u></em> x² to show the positive upward shift.

Your full equation would look like this: g(x) = 2x² + 1

Dilation: this just means that every point on the parent function was double (or whatever the factor is) in the transformed function.
