4 0

Answer:

a

Step-by-step explanation:

y=6x²+12x+2

y=4x²+16x+16

6x²+12x+2=4x²+16x+16

6x²-4x²+12x-16x+2-16=0

2x²-4x-14=0

x²-2x-7=0

x²-2x+1-1-7=0

(x-1)²=8

x-1=±√8=±2√2

x=1±2√2

x≈1±2.83

x≈3.83,-1.83

x=2√2 -1≈1.828≈1.83

A large concrete mixing machine can mix a certain amount of concede in 12 hours, while a smallet one can mix
Andrews [41]

Answer:

[(1/12)(5/5) + (1/20)(3/3)](x hours) = 1

(5/60 + 3/60)x = 1

(8/60)x = 1 we can reduce 8/60 by dividing out a 4

(2/15)x = 1 x both sides by 15/2

x = 15/2

x = 7 1/2 or 7.5 hours

Based on the sample of 500 people, 42% owned cats. Calculate the test statistic. Round to two decimal places.
Tanzania [10]

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.
