Answer:
Gabe worked 65, Abe worked 62 and Babe worked 69.
Step-by-step explanation:
Let Gabe = x
Therefore, Abe worked: x-3 and Babe worked x+4
So,
x+(x-3)+(x+4)=196
3*x+1=196
3*x=195
x=65
Then,
x-3= 62
x+4=69
Answer:
a =3
b = -5
c = 4
Step-by-step explanation:
3x^2+4=5x
Subtract 5x from each side
3x^2-5x+4=5x-5x
3x^2-5x+4=0
The equation is in the form
ax^2 +bx+c =0
a =3
b = -5
c = 4
Answer:
Mr Blake's science class
Step-by-step explanation:
The standard deviation is a measure of variation.
It tells us how far each of the data set in the distribution are far from the mean of the distribution.
The average score of students in Mr. Blake's science class was 73 with a standard deviation of 11, while the average score of students in Mrs. Arnold's class was 75 with a standard deviation of 10.
Since 11>10, Mr Blake's science class is more variable than Mrs. Arnold's class.
Correct answer is B. Begin it with the words "Antarctica is".
<h3>
what is Antarctica? </h3>
Antarctica The least inhabited and most southern continent on Earth is. It encompasses the geographical South Pole and is almost fully south of the Antarctic Circle, bordered by the Southern Ocean. With a surface area of 14,200,000 km2, Antarctica is the fifth-largest continent, being nearly twice the size of Australia and larger than Europe (5,500,000 sq mi). Ice blankets the majority of Antarctica, with an average thickness of 1.9 km (1.2 mi).
The continent with the greatest average elevation is Antarctica, which also tends to be the coldest, driest, and windiest overall. With around 200 mm (8 in) of yearly precipitation at the shore and much less inland, it is primarily a polar desert.
