Answer:
On the science test the point ( 0 , 424 ) the intercepts is bigger
Step-by-step explanation:
The relation hours spend vs science test score is
y = 6.5*x + 424
And the relation hours spend vs Maths test score is
y = 7.2*x + 34.7
Making x = 0 ( student does not study at all ) we get:
For science score test woul be
y = 0 + 424
In case of maths
y = 0 + 34.7
That mean student without studying will get better score in science.
The point ( 0 , 424) ( science ) represents the interception with y axis
in Maths case such point is ( 0 . 34.7)
Answer:
x-int: (3, 0)
y-int: (0, 2)
Step-by-step explanation:
The x-int is found when y = 0. Set <em>y</em> to 0 to solve for the x-int.
The y-int is found when x = 0. Set <em>x</em> equal to 0 to solve for the y-int.
Answer:
100%
Step-by-step explanation:
Use conditional probability:
P(B | A) = P(B and A) / P(A)
P(B | A) = (12/28) / P(A)
We need to find the probability that a student studies art.
P(A or B) = P(A) + P(B) − P(A and B)
24/28 = P(A) + (12+12)/28 − 12/28
P(A) = 12/28
P(B | A) = (12/28) / (12/28)
P(B | A) = 1
What this means is that all of the students who study art also study biology.
Answer:
![\frac{-27}{40}](https://tex.z-dn.net/?f=%5Cfrac%7B-27%7D%7B40%7D)
Step-by-step explanation:
First we need to write in correct form :
![\frac{-3}{8}:\frac{5}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B-3%7D%7B8%7D%3A%5Cfrac%7B5%7D%7B9%7D)
We know how to divide fractions. If we can divide numerator by numerator, denominator by denominator, we just do it. In this example we can not do that.
So, we rewrite first fraction and multiply by reciprocal second ( numerator and denominator change place)
![\frac{-3}{8} *\frac{9}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B-3%7D%7B8%7D%20%2A%5Cfrac%7B9%7D%7B5%7D)
Now, multiply numerator by numerator, denominator by denominator :
![\frac{-27}{40}](https://tex.z-dn.net/?f=%5Cfrac%7B-27%7D%7B40%7D)
Answer: 198 ft^2
total Area = Area of rectangle + area of trapzoid
= base*height + .5(b1+b2)*height
9*18+.5(9+3)6
162+36
