4(1/2x7)=12 <=> x28/2=12
x=12*2/28=24/28=12/14=6/7
Elimination
A, they are both linear
linear equations are sometimes given by y=mx+b, equation A, if graphed, produces a hyperbola which is not linear so statement A is false
B they areboth non-linear
equationb is linear so this is false
C equation a is non-linear and equation b is linear
true
C is the answer
Answer:
b.line segment
Step-by-step explanation:
line segment is a piece and or part of a line having two end points
Answer:
a. P=0.01222
b. P=0.98778
c. The probability of rejecting the claim is now P=0.00298.
Step-by-step explanation:
In this case, we evaluate the sampling distribution for a population proportion π=0.8 with a sample size of 25.
We need to calculate the probability of getting a sample mean below 15, which means p=15/25=0.6.
The standard deviation of the sampling distribution is:

The z value por p=0.6 is

The probability of having a sample mean less than 15 is

The probaiblity of not rejecting the claim is 1-0.01222=0.98778
If the value 15 is replaced by 14, we have a new value of p=14/25=0.56.
There will be less chances of rejecting the hypothesis.
