Question 60:
The answer is B. 25.57.
Mean is calculated by adding up all the values of a data set, and then dividing that sum by the amount of values.
25, 32, 16, 21, 30, 18, 37=179
179÷7=25.57
Question 61:
The answer is A. 102.
Mode is the number in a data set that appears most often. 102 shows up twice, while the other values only appear once. So 102 is the mode.
Answer is 8
Work Shown:
f(x) = sqrt(5*x + 4)
f(12) = sqrt(5*12 + 4) ... replace every x with 12
f(12) = sqrt(60 + 4)
f(12) = sqrt( 64 )
f(12) = 8
Answer: g(4)= -60
Step-by-step explanation:
You just plug in 4 into the equation
g(4)= 2√4 - (4)³
g(4)= 2√4 - (4)³
g(4)= 2·2 - (64)
g(4)= 4 - 64
g(4)= -60
Answer:
X=6
Step-by-step explanation:
Turning the question into a formulae
2X + 5 > 16; and 2X + 5 < 29
Let’s start by calculating the lower limit
2X + 5 = 16
X = (16–5)/2
X = 11/2 = 5.5
X > 5.5
The lowest value of X is infinitesimally close to 5.5, but greater than 5.5.
Answer:
8
Step-by-step explanation:
Evaluate 3x^2+x-2 when x=-2
Just plug in x = - 2 into the expression
= 3(-2)^2 + (-2) -2
= 3(4) -2 - 2
= 12 - 4
= 8
