Answer:
A. Discriminant = 116
B. Number of solutions for the quadratic equation = 2
C. Type of solutions (circle one):Imaginary
D. Type of solutions (circle one):irrational
Step-by-step explanation:
The given quadratic equation is

We rewrite in standard form to get;

The discriminant is

where a=1, b=8, c=-13
We substitute to get:



Since the discriminant is great than zero, we have two distinct real roots
Answer:
$5.3
Step-by-step explanation:
<u>1) Ask yourself: How much money is left to spend? </u>
<em>- Subtract the cost to rent the park shelter: </em>
3,500 - 250 = 3,250
<em>- Find the total amount of money spent on gifts for students: </em>
300 * 5.50 = 1,650
<em>- Subtract the total money spent on gifts for students: </em>
3,250 - 1,650 = 1,600
<u>2) Ask yourself: How much can be spent </u><u>per student</u><u>? </u>
<em>- Divide the money left by the number of students: </em>
1,600 / 300 = 5.3
Answer:
49.865%
Step-by-step explanation:
Given that:
μ = 4 ; σ = 1
For x = 4
P(x < 4) :
Z score (x - μ) / σ
P(x < 7) - P(x < 4)
((7 - 4) / 1) - ((4 - 4) / 1)
P(Z < 3) - P(Z < 0)
Usibg the Z probability calculator :
0.99865 - 0.5
= 0.49865
= 0.49865 * 100
= 49.865%
