<h3>
Answer: 49/100</h3>
=========================================================
Explanation:
There are 7 dimes and 3 pennies, leading to 7+3 = 10 coins total.
The probability of not picking a penny is 7/10. If the first coin is put back, then the probability doesn't change for the second selection.
The probability of getting two dimes is (7/10)*(7/10) = 49/100 when the first coin is replaced.
If the first coin is not replaced, then the answer would be (7/10)*(6/9) = 42/90 = 7/15
Answer:
11/12
Step-by-step explanation:
Multiply 1/4 times 3/3 and 2/3 times 4/4. That gives you 3/12 + 8/12. Add that together and you get 11/12
4,016
4,000
+
16
Which would equal 4,016
Answer: Nonlinear; power of x is greater than 1 (Bottom right corner)
Explanation:
The equation y = x^2 - 1 is known as a quadratic since the largest exponent here is 2. This equation cannot be written in slope intercept form y = mx+b, so that's why it's not linear. You can also graph y = x^2-1 to get a curved parabola. The graph must be a straight line if you want a linear equation.
