Answer:
About 4 days
Step-by-step explanation:
Convert 39 and 42 degrees C to a z score and then use the z-table
Answer:
y=0
Step-by-step explanation:
Rewrite Evaluate Powers:
3
Calculate:
Solve using substitution:
Solve the equation for t:
t=-3
t=1
Substitute back to t=3^y
3^y=-3
3^y=1
y∉R
y=0
First step is to plot all the given coordinates in the xy plane.
Notice that after plotting the points A, B, C and D, we have got the figure ABCD is a trapezium with bases AD = 4 units, BC = 6 units and height: DE= 5 units.
Formula to find the area of trapezium is:
Area =
=
=
= 5 * 5
= 25 square units.
So, third choice is correct.
Hope this helps you!
For future reference, it would be easier to say 8 and a half miles. Just a tip for better understanding. Now I am pretty sure the answer would be the first one. You would take the total divided by the variable of each day to get the number of days
