Last question of my homework pls &lt;3​
dimaraw [331]

Answer:

J(2, 5 )

Step-by-step explanation:

Using the section formula

x_{J} = \frac{1(-2)+2(4)}{2+1} = \frac{-2+8}{3} = \frac{6}{3} = 2

y_{J} = \frac{1(1)+2(7)}{2+1} = \frac{1+14}{3} = \frac{15}{3} = 5

Thus J = (2, 5 )

The average household income for a recent year was $30,000. five years earlier the average household income was $24,500. assume
ikadub [295]

Using hypothesis test, we conclude that there is evidence to believe that the average household income has increased.

According to the question,

The average household income for a recent year (x₁⁻) = $30,000

The average household income for a recent year (x₂⁻) = $24,500

sample sizes n₁ = n₂ = 34

standard deviation of both samples were $24,500. Thus, s₁ = s₂ = $5928.

Null hypothesis:  There is no evidence to believe that the average household income has increased.

H₀ : μ₁ ≤ μ₂

Alternative hypothesis:  There is evidence to believe that the average household income has increased.

H₁: μ₁ > μ₂  

To check hypothesis we have the formula

Standard error=  \sqrt{\frac{s_{1} ^{2} }{n_{1} } + \frac{s^{2} _{2} }{n_{2} }  }

= \sqrt{2067128.4706}

= 1437.7512

Thus, standard error is $1437.7512.

Formula for test statistic = [(x₁⁻ -  x₂⁻) - (μ₁ - μ₂)]/standard error

= [(30000 -  24500) - 0]/1437.7512

= 3.8254

The critical value of z at 5% level of significance is 1.6449.

Here, the calculated value is greater than the critical value so we reject H₀.

Hence using hypothesis test, we conclude that there is evidence to believe that the average household income has increased.

Wewaii [24]

Answer:

17.5

Step-by-step explanation:

formula:

y=k(x)

direct variation^^^

y=7, x=2

substitute it in the formula

7=(k)2 or 7=2k

7/2 or 3.5= k, k is the constant

now substitute k to the problem

y=5k

y=5(3.5)

y=17.5
