Answer:
The answer is A because all points less than -3 are shaded
Out of the sampled 30 employees 22 worked for at least 10 years.
point estimate (p^) = 22/30 = 0.73
x + y = 24 where x and y are the 2 parts of diagonal Other diagonal wil be smaller that 24.
x^2 + z^2 = 13^2
y^2 + z^2 = 20^2 where z = 0.5 * length of smaller diagonal)
form last 2 equations
y^2 - x^2 = 20^2 - 13^2 = 231
now y = 24-x so we have
(24 - x)^2 - x^2 = 231
576 - 48x = 231
48x = 345
x = 7.1875
z^2 = 13^2 - 7.1875^2 = 117.34
z = 1.83
so smaller diagonal = 21.66 cm
looks like its the third choice.
Step-by-step explanation:
f(-1)=3×(-1)²-4×(-1)
=3×1-4×(-1)
=3+4
=7
hope it helps.
