The sum of two numbers is -18. If the first number is 10, which equation represents this situation, and what is the second numbe

professor190 [17]

Answer:

The equation that represents this solution is: 10+x= -18

The second number is -28.

Step-by-step explanation:

To solve for this, we first need to make an equation. We know that one of the numbers, the first one, is 10, but the second is unknown. Because of this, we will label the unknown number x. We also know that the -18 is the sum, so we know it will be behind the equal sign. Using this info, we can make the following equation.

10+x= -18

We did 10 because it was the first, added it with the unknown x, and it all equals -18. This would be your equation.

To find the answer, you need to solve the equation.

10+x= -18

First, since we are adding ten to both sides, subtract ten from both sides.

10-10+x= -18-10

Now, solve. Remember that subtracting a positive number is the same as adding a negative number.

x= -28

Now, check. Does 10+ -28 equal -18? Yes, so we are correct.

Data on pull-off force (pounds) for connectors used in an automobile engine application are as follows:

hjlf

Answer:

a) 75.62

b) 75.2

Step-by-step explanation:

Data provided:

79.9,75.1,78.2,74.1,73.9,75.0,77.6,77.3,73.8,74.6,75.5,74.0,74.7,75.9,72.6,73.8,74.2,78.1,75.4,76.3,75.3,76.2,74.9,78.0,75.1,76.8

Sum = 1966.3

Total number of observations, n = 26

a) Mean is given as:

Mean = $\frac{\textup{Sum of all observations}}{\textup{Total number of observations}}$

or

Mean = $\frac{\textup{1966.3}}{\textup{26}}$

or

Mean = 75.62

b) For value that separates the weakest 50% of the connectors i.e median or the 50th percentile

Arranging the data in ascending order:

72.6, 73.8, 73.8, 73.9, 74, 74.1, 74.2, 74.6, 74.7, 74.9, 75, 75.1, 75.1, 75.3, 75.4, 75.5, 75.9, 76.2, 76.3, 76.8, 77.3, 77.6, 78, 78.1, 78.2, 79.9

i = $\frac{\textup{n}}{\textup{2}}$

or

i = $\frac{\textup{26}}{\textup{2}}$ = 13

When the number of observations is even the formula for median is:

$Median = \frac{\frac{n}{2}+\frac{n+2}{2}}{2}$

or

$Median = \frac{\frac{26}{2}+\frac{26+2}{2}}{2}$

or

$Median = \frac{13th+14th}{2}$

or

$Median = \frac{75.1+75.3}{2}$

or

Median = 75.2
