Answer:
a) y does NOT vary directly with x
b) y = 2.5x -6.5
Step-by-step explanation:
If variation were direct the ratios of y to x would be constant. They are not:
6/5 ≠ 11/7
y does not vary directly with x.
__
y changes by 5 from 6 to 11 when x changes by 2 from 5 to 7. Then the slope of the linear function rule is (change in y)/(change in x) = 5/2. Using a point-slope form of the equation of a line, we can write the rule as ...
y = m(x -h) +k . . . . . . . . for a line of slope m through point (h, k)
y = (5/2)(x -5) +6
y = 2.5x -6.5 . . . . . simplify
Okay so first what you would do is figure out what 3/5 is as a decimal so you would divide 3 by 5 which is 0.6 so the percentage is 15.6%
Next turn it into a fraction which would be 15.6/1
Then multiply the numerator and denominator by 10
15.6= 15.6/1= 156/10
then to put it in simplest form divide 10 by 156 and that would be 15 and 6/10

Answer:
<h2><u>First question</u></h2>
Vertically opposite angles are equal
So
x = 75°
<h3><u>Second question</u></h3>
Vertically opposite angles are equal
So
5y = 135°
Divide both sides by 5
y = 27
Hope this helps you
Answer:
a)
b)
c)
d)
Step-by-step explanation:
Let X the random variable of interest and we know that the distribution is given by:
And for this problem we can use the cumulative distribution function in order to solve the items:
Part a
We want to find this probability:
Part b
Part c
And we can calculate the probability with this difference:
Part d
Since we have a continuous distribution the the probability for an unique value would be:
Answer:
- 5/8
Step-by-step explanation:
-9-11/24-(-8)= -20/32 = - 5/8
