Answer:

3) 6.3

7) 14.7

Step-by-step explanation:

Use ratios to solve the table

10.5/5 = x/3

cross multiply

31.5 = 5x

x = 6.3

10.5/5 = x/7

73.5 = 5x

x = 14.7

Expand and simplify 5(x-1)-3(x+4)
ludmilkaskok [199]
Question:

Expand and simplify 5(x - 1) - 3(x + 4)

Answer:

1.) Use the distributive property to solve this equation:

5(x - 1) = 5x - 5

3(x + 4) = 3x + 12

2.) Put it in the equation:

5x - 5 - 3x + 12

3.) Group them:

5x - 3x - 5 + 12

4.) Simplify:

2x - 7
which is the answer.



Hope this helped! :))

Each time a component is tested the trial is a success (S) or failure (F). Suppose the component is tested repeatedly until a su
babymother [125]

Answer:

(a)\ \{SSS\}

(b)\ \{FSSS\}

(c)\ \{FFSSS, SFSSS\}

(d)\ \{FFFSSS, SSFSSS, SFFSSS, FSFSSS\}

(e)\ \{FFFFSSS, FFSFSSS, FSSFSSS, SSFFSSS, SFSFSSS, SFFFSSS, FSFFSSS\}

Step-by-step explanation:

Given

S\to Success

F\to Failure

n \to 3 Consecutive trials until S happens

Y \to Number of trials

For every possible outcome, the last 3 must be SSS. So, we have:

(a)\ Y = 3

The only possibility here is: \{SSS\}

because 3 trials implies that all outcomes must be S.

(b)\ Y = 4

The only possibility here is:

\{FSSS\}

because 4 trials implies that the first outcome must be F

 

(c)\ Y = 5

The possibilities are:

\{FFSSS, SFSSS\}

because 5 trials implies that the first and the second outcomes must be FS or SF.

(d)\ Y = 6

The possibilities are:

\{FFFSSS, SSFSSS, SFFSSS, FSFSSS\}

because 6 trials implies that the first three outcomes are: FFF, SSF and SFF

(e)\ Y = 7

The possibilities are:

\{FFFFSSS, FFSFSSS, FSSFSSS, SSFFSSS, SFSFSSS, SFFFSSS, FSFFSSS\}

because 7 trials implies that the first three outcomes are: FFFF, FSSF and SSFF and FFSF (similar to (e))
