Re-write
8x + 14y = 4 (1)
-6x - 7y = -10 (2)

multiply (1) by 3 and (2) by 4
now you have
24x + 42y = 12 
-24x - 28y = -40
-------------------------add
           14y = -28
               y = -2

8x + 14y = 4
8x + 14(-2) = 4
8x - 28 = 4
8x = 32
  x = 4

answer
x = 4 and y= -2

Answer:

Yes, we can conclude that the ship is older than the national average

Step-by-step explanation:

Population mean, μ = 23.6

Sample mean, xbar = 26.7

Sample size, n = 38

H0 : μ = 23.6

H0 : μ > 23.6

The test statistic :

(xbar - μ) ÷ (σ/√(n))

(26.7 - 23.6) ÷ (5.2/√(38))

3.1 / 0.8435513

Test statistic = 3.675

Decision region :

Reject H0 ; if |Tstatistic| > |Tcritical|

Since we are given the sample standard deviation ; we use the T test distribution

df = 38 - 1 = 37

Tcritical at df = 37 ; α = 0.05 ; rigth tailed :

Tcritical(0.05, 37) = 1.687

3.675 > 1.687 ; Hence, we reject H0 and conclude that there is enough evidence that this type of shop is older than the national average.

Write an ordered list of five numbers whose values are between 50.98 and 51.6. Tell whether your list is from least to greatest
Vadim26 [7]

One <em><u>possible answer</u></em> is:

51.0, 51.1, 51.2, 5.13, and 51.4; the list is from least to greatest.

Explanation:

51.0 can be written as 51.00.  Comparing this to 50.98, we can see that 51.00 is larger.

51.1 is larger than 51.0; 51.2 is larger than 51.1; 51.3 is larger than 51.2; and 51.4 is larger than 51.3.  All of these numbers are also smaller than 51.6.
