Answer:
s = -133/5 = -26.600 ⬇️
Step-by-step explanation:
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(0 - 5 • (s + 30)) - -17 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
-5s - 133 = -1 • (5s + 133)
Equation at the end of step 3 :
-5s - 133 = 0
Step 4 :
Solving a Single Variable Equation :
4.1 Solve : -5s-133 = 0
Add 133 to both sides of the equation :
-5s = 133
Multiply both sides of the equation by (-1) : 5s = -133
Divide both sides of the equation by 5:
s = -133/5 = -26.600
One solution was found :
s = -133/5 = -26.600

Answer:
z= 3.63
z for significance level = 0.05 is ± 1.645
Step-by-step explanation:
Here p = 42% = 0.42
n= 500
We formulate our null and alternative hypotheses as
H0: p= 0.42 against Ha : p> 0.42 One tailed test
From this we can find q which is equal to 1-p= 1-0.42 = 0.58
Taking p`= 0.5
Now using the z test
z= p`- p/ √p(1-p)/n
Putting the values
z= 0.5- 0.42/ √0.42*0.58/500
z= 0.5- 0.42/ 0.0220
z= 3.63
For one tailed test the value of z for significance level = 0.05 is ± 1.645
Since the calculated value does not fall in the critical region we reject our null hypothesis and accept the alternative hypothesis that more than 42% people owned cats.
Answer:
The y intercept is (0,13)
The equation of the line is y = -2x+13
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -2x+b
Substituting the point
3 = -2(5) +b
3 = -10 +b
Add 10 to each side
13 =b
The y intercept is (0,13)
The equation of the line is y = -2x+13
