Answer:
f(6) = - 75 , g(- 5) = - 8
Step-by-step explanation:
substitute x = 6 into f(x) , that is
f(6) = - 2(6)² - 3 = - 2(36) - 3 = - 72 - 3 = - 75
substitute x = - 5 into g(x) , that is
g(- 5) = 2(- 5) + 2 = - 10 + 2 = - 8
I'm thinking line 2 and 3 are Parallel
P(C/Y) = 15/30 = 1/2 = 0.5
Answer:
a.) 26< a <u>28 </u>
b.) 4
Step-by-step explanation:
a.) After looking at the age in years collum you can notice that all of ages have a difference of 2. With this you can infer that the missing number is 28.
b.) To find the mean add up all the numbers in the frequency column.
3+2+7+8+0=20
Divide that by the amount of numbers. There are 5 numbers so 20/5=4.
Hope this helps!
