Answer:Julie's average score was 76
Step-by-step explanation:
The formula for Average or mean is expressed as
Average = sum of terms / total number of terms.
Julie's first three test scores in biology were 65, 90 and 73.
The sum of the scores would be
65 + 90 + 73 = 228
The number of terms is the number of subjects. Therefore, the number of terms is 3. Therefore,
Average = 228/3 = 76
p(x) × q(x)
= (3x² - x + 1) × (2x² + 3x - 2)
= 6x⁴ + 9x³ - 6x² - 2x³ - 3x² + 2x + 2x² + 3x - 2
= 6x⁴ + 7x³ - 7x² + 5x - 2
B, You plug in the numbers like 3e^(3*.03) for 3.3
Answer:
C
Step-by-step explanation:
The lower quartile is the value at the left side of the box, that is
LQ = 14
The upper quartile is the value at the right side of the box, that is
UQ = 28
The median is positioned at the vertical line inside the box. that is
Median = 21
Answer:
12
Step-by-step explanation:
For our problem since we only in 10 am:
I'm going to let x=4 represent the time 10:04 am
which means I'm going to let x=17 represent 10:17am.
So when x=4, y=23 miles and when x=17,y=179 miles.
You have two points.
You can use the formula 
.
Or just line the points up vertically and subtract them vertically, then put 2nd difference over first difference. Like this:
( 17 , 179)
-( 4 , 23)
-----------------------
13 156
So the slope is 156/13=12 miles/hour.
