You flip 3 coins 20 times and record the number of heads. The results are listed below. 2, 1, 0, 2, 2, 0, 2, 2, 3, 2, 1, 2, 1, 2

Assuming a is 0, b is 1, c is 2, d is 3
a= 2, b= 7, c= 9, d= 2
So that gives you
4×5^2-5×3^2
First you have to do the exponents
5^2=25
3^2=9
Now you have 4×25-5×9
4×25=100
5×9=45
100-45=55
55 is the answer.
Answer:
A non-linear graph is a graph that is not a straight line. A non-linear graph can be described by an equation.
Step-by-step explanation:
X + y + z = 54
y = x + 1
z = x + 2
x + x + 1 + x + 2 = 54
3x + 3 = 54
x + 1 = 18
x = 17
y = 17 + 1 = 18
z = 17 + 2 = 19
the three integers are 17, 18, and 19
Answer:
0.9
Step-by-step explanation:
Y = B0 + B1X
B1 is the slope an from the question the slope estimate is 0.5
S.E= standard error at 0.2
At 5percent Level of significance, the z value for the test is equal to 1.96
We are required to find out the largest value of b for which the null hypothesis would be accepted.
0.5 + 1.96 x 0.2
= 0.892
Approximately 0.9
