Answer: 45 degrees
Step-by-step explanation:
There have been 5 tests so far.
The final will count for two more.
So the grand average score will be the average of 7 test scores.
If the grand average score is to be 80, then all 7 components
will add up to (7 x 80) = 560 .
The tests she has already taken add up to
(75 + 84 + 74 + 59 + 94) = 386
So the "two" tests she's about to take need to add at least
(560 - 386) = 174 .
So she needs to score at least (174/2) = 87 on the final.
It'll be averaged into the others as if it were two tests,
so it'll add 174 points to the others, and the whole set
of ' 7 ' tests will average 80 .
<span>The answer is: the least amount is 105.35 and the greatest amount is 105.44. If the number after the one you want to round is 5 or bigger, you need to round up the number. For instance, 105.35 is rounded to 105.4 which is equal to 105.40. If the number after the one you want to round is smaller than 5, you need to round down the number. For instance, 105.44 is rounded to 105.4 which is equal to 105.40.</span>
Answer:
it would be
The dependent variable is distance, the equation is y = 35x, and the dragonfly will travel 840 miles
Step-by-step explanation:
By the graph it can be seen that the distance a dragonfly can travel is dependent on the certain number of hours.
∴ Dependent variable : Distance (on y axis)
The equation of straight line is given by :-
, here m is the slope of the line and c is the initial value of y at x=0.
From the given graph, the slope of the given line passing from (0,0) and (2,70) will be :-
Also, the value of y = 0 at x=0.
∴ The equation of the given line :
At x=24,
∴ The dragonfly will travel 840 miles in 24 hours.
Answer:
D. 550 years
Step-by-step explanation:
Firstly, you need to understand the meaning of B.C.E. and C.E. B.C.E. means "Before common era", where "common era" is the year where Jesus Christ was born (I will just call it "The Year" since the name is so long). The date has been used as a dating system for many years.
In this case, 300 B.C.E. means 300 years before "The Year" whereas 250 C.E. means 250 years after "The Year". Thus, the total would be:
300 + 250 = 550 years
