James is 8 years old. Last year, his father was 4 times as old as he was. In how many years' time will their combined age be 51?

Snowcat [4.5K]

Last year He was 7 years old.

His father is 4 times the age 7 x 4 = 28

Last year his dad was 28, so this year he is 29.

Combined age this year = 29 + 8 = 37

51 - 37 = 14 years

14/ 2 people = 7 years

8 + 7 = 15

29 + 7 = 36

15 + 36 = 51

It will take 7 years.

Below are tabulated a number of Rockwell G hardness values that were measured on a single steel specimen. Compute

Mashcka [7]

Answer:

a) 48.408

b) 1.235

Step-by-step explanation:

The average hardness value xbar can be computed as

xbar=sum of values/number of values

xbar=(46.5+46.9+49.4+50.3+49.8+48.8+47+47.7+48.3+49.4+47.8+49)/12

xbar=580.9/12

xbar=48.408 (rounded to 3 decimal places).

The average hardness value is 48.408.

The standard deviation hardness value s can be computed as

$s=\sqrt{\frac{sum(x-xbar)^2}{n-1} }$

x x-xbar (x-xbar) ²

46.5 -1.90833 3.64174

46.9 -1.50833 2.27507

49.4 0.99167 0.98340

50.3 1.89167 3.57840

49.8 1.39167 1.93674

48.8 0.39167 0.15340

47.0 -1.40833 1.98340

47.7 -0.70833 0.50174

48.3 -0.10833 0.01174

49.4 0.99167 0.98340

47.8 -0.60833 0.37007

49.0 0.59167 0.35007

Total 16.7692

$s=\sqrt{\frac{16.7692}{12-1} }$

$s=\sqrt{\frac{16.7692}{11} }$

$s=\sqrt{1.5245}$

$s=1.2347$

s=1.235 (rounded to 3 decimal places)

The standard deviation hardness value is 1.235.

I need help (please show your work)

oksano4ka [1.4K]

Answer:

the solution is (-4, 3)

Step-by-step explanation:

if you were to graph y = -7/4x - 4 you could plot your first point at (0, -4) and get your second point by going up 7 units (from (0, -4) and to the left by 4

if you were to graph y = -1/4x + 2 you could plot your first point at (0, 2) and get your second point by going up 1 unit (from (0, 2) and to the left by 4

the second point plotted for each equation will be the point of intersection, (-4, 3)
