Answer:
0 real # solution
Step-by-step explanation:
b^2-4ac<1 is equal to 0 real number solution and
-5(2+1)=-22+10
-5(2+1)=-12
which is less than 1
Using the normal distribution, the area underneath the shaded region <u>between the two z-scores</u> is given by:
C. 0.6766.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
Hence, for this problem, the area is the <u>p-value of z = 0.75 subtracted by the p-value of z = -1.3</u>.
Looking at the z-table, the p-values are given as follows:
Then:
0.7734 - 0.0968 = 0.6766.
Which means that option C is correct.

Answer: what kite can you put the pic
Step-by-step explanation:
Answer:
Question 7
Answer : 1200 inches squared
Question: 8
Answer: 84 centimeters squared
Question: 9
Answer: 2304 feet squared
Step-by-step explanation:
1) Q7: Parallelogram
A=BH
base 30 inch X height 40 inch = 1200 inches squared
2) Q8: Rhombus
A=pq
/2
Multiply the two diagonals then divide by 2
Diagonals 14 cent X Diagonal 12 cent divided by 2 = 84 centimeters squared
3) Q9: Trapezoid
A= (B1+B2)H/2
Add the two bases times the height divide by 2
gives you:
2304 feet squared
