Point (3,0) is system solution.

<h3>What is inequality?</h3>

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

We have

y> -2

x + y <4

  • For (1,-5):

First inequation:

-5> -2 (incorrect)

Second inequality:

1-5 <4 (correct)

  • For (3,0):

First inequation:

0> -2 (correct)

Second inequality:

0+3 <4 (correct)

  • For (-1,-2):

First inequation:

-2> -2 (incorrect)

Second inequality:

-1-2 <4 (correct)

  • For (1,5):

First inequation:

5> -2 (correct)

Second inequality:

1+5 <4 (incorrect)

Hence, Point (3,0) is system solution.

Answer:

The jar contains 132 grams of zinc

Step-by-step explanation:

The ratio of zinc to copper is 4:15, if there were 495 grams of copper, then that means the ratio was multiplied by the quotient of 495 and 15, which is 33. 33 * 4 is 132, so that is the total amount of zinc in the jar.

Heights of men on a basketball team have a bell shaped distribution with a mean of 173 cm and a standard deviation of 8 cm using
ASHA 777 [7]
I have a similar problem here with a slightly different given. 

Heights of men on a baseball team have a bell shaped distrubtion with a mean of 172cm and a standard deviation of 7cm. Using that is the empirical rule, what is the approximate percentage of the men between the following values? 
a) 165 cm and 179cm 
<span>b) 151cm and 193cm
</span>
The solution is:

 <span>a. (165-172)/7 = -1, (179-172)/7 = 1, % by empirical rule = 68% 

b. (151-172)/7 = -3, (193-172)/7 = 3, % by empirical rule = 99.7%
</span>
I hope that by examining the solution for this problem, it could help you  answer your problem on your own.

(i)If the circumference of the circle is 88 cm ; Find the diameter. <br> (Take π = 22/7 )
xxTIMURxx [149]
<h3>Given:</h3>

Circumference of the circle = 88 cm

π = 22/7

<h3>To Find:</h3>

The Diameter of the circle.

<h3>Formula:</h3>

Circumference of circle = 2πr

r = radius

<h3>Solution:</h3>

Circumference of the circle = 2πr = 88 cm

Circumference of the circle = πr = 88/2 = 44 cm

Circumference of the circle = r = 44 × 7/22 = 14 cm

r (radius) = 14 cm

d (diameter) = 2r = 2(14) = 28 cm

<h2>Answer:</h2>

Diameter of the circle = 28 cm
