What is the value of x in the <br> triangle?

Makovka662 [10]

Answer:

x = 75°

Step-by-step explanation:

Sum of angles in a triangle: 180°

So,

50°+55°+x=180°

105°+ x = 180°

Subtract 105° from both sides

x = 75°

A manufacturer knows that their items have a normally distributed lifespan, with a mean of 15 years, and standard deviation of 3

Gala2k [10]

Answer:

The probability that their mean life will be longer than 13 years = .9943 or 99.43%

Step-by-step explanation:

Given -

Mean $(\nu )$ = 15 years

Standard deviation $(\sigma )$ = 3.7 years

Sample size ( n ) =22

Let $\overline{X}$ be the mean life of manufacturing items

the probability that their mean life will be longer than 13 years =

$P(\overline{X}> 13)$ = $P(\frac{\overline{X} - \nu }{\frac{\sigma }{\sqrt{n}}}> \frac{13 - 15 }{\frac{3.7}{\sqrt{22}}})$ $(Z =\frac{\overline{X} - \nu }{\frac{\sigma }{\sqrt{n}}})$

= $P(Z> -2.53)$

= $1 - P(Z < -2.53)$ Using Z table

= 1 - .0057

= .9943
