Answer:

84 is 7 x n.

n = 84 ÷ 7

n = 12

Step-by-step explanation:

You can solve the problem by using algebraic expressions in looking for the value of n.

Let n be the no. of families in City B that have a dog.

City A is 7 times as many families with a dog than City B. You can express this as: City A = 7 x n

Since you know that City A has 84 families owning a dog. Then you can express this as: 84 is 7 x n or 84 = 7 x n.

Let's get the value of n.

84 = 7 x n

n = $\frac{84}{7}$ or n = 84 ÷ 7

n = 12

There are 12 families in City B that have a dog.

Answer:

I would reject the null hypothesis.

Step-by-step explanation:

The test is a two-tailed test because it is stated that the alternate hypothesis is two-sided.

Degree of freedom = n - 1 = 350 - 1 = 349

At 349 degrees of freedom and 5% significance level, the critical values are -1.96702 and 1.96702

Conclusion:

Reject the null hypothesis because the test statistic 3 falls outside the region bounded by the critical values -1.96702 and 1.96702.

Answer:

Answer is option d 

Step-by-step explanation:

$given \: expression \: is \: {(x - 3)}^{2} = 5 \\ {x}^{2} - 6x + 9 = 5 \\ subtracting \: 5 \: on \: both \: sides \: we \: get \\ {x}^{2} - 6x + 4 = 0 \\ on \: solving \: the \: quadratic \: equation \: by \\ \: completing \: square \: method \\ {x}^{2} - 6x = - 4 \\ adding \: {3}^{2} on \: both \: sides \: w e\: get \\ {x}^{2} - 6x + {3}^{2} = {3}^{2} - 4 \\ {(x - 3)}^{2} = 5 \\ x - 3 + = \sqrt{5} \\ x = \sqrt{5 } + 3$
