The answer is D I believe.
Answer:
Step-by-step explanation:
Evan has 43 and Brayden has 42. Reid has 76 and Bryce has 23. Which pair of boys has more? How much more do they have?
Reid and Rryce have more. If you add 43 and 42 you get 85 and when you add 76 and 23 you get 99. So now subtract 99 and 23 which is 76.
Step-by-step explanation:

0.7 is the new probability of the event being sold out given that total number of events is 7 and 5 events are sold out. This can be obtained by using the formula for probability.
<h3>Find the new probability of the event being sold out:</h3>
Probability is the chance of occurrence of an event.
⇒ The formula for finding probability,
Probability =
Here it is given in the question that,
- Total number of outcomes = Total number of events = 7
- Number of events sold out = 5
- Number of events not sold out = 2
Therefore by using the formula of probability we get,
⇒ Probability (Junior Athletics being sold out) = 
Probability (Junior Athletics being sold out) = 
Probability (Junior Athletics being sold out) = 5/7
⇒ Probability (Junior Athletics being sold out) = 0.7
Hence 0.7 is the new probability of the event being sold out given that total number of events is 7 and 5 events are sold out.

Answer:
2 Real Roots
Step-by-step explanation:
The discriminant (D) is found using the formula b^2+4ac for the equation ax^2+bx+c.
If D>0 there are two real roots, D=0 one real root and D<0 no real roots.
D = b^2+4ac
D = 10^2+4(-4)(-8)
D = 100+32*4
D = 100+128
D = 228
since 228>0
There are 2 real roots
