Answer:

a = 17
∠ABC = 78°

Step-by-step explanation:

The marked angles form a linear pair, so have a sum of 180°.

(4a +10) +(6a) = 180

10a = 170 . . . . . . . . . . subtract 10

a = 17 . . . . . . . . . . . . . divide by 10

Then the measure of angle ABC is ...

∠ABC = 4a +10 = 4(17) +10 = 68 +10 . . . . . substitute 17 for 'a'

∠ABC = 78°

A manufacturer produces widgets that are packaged in boxes of 100. The probability of a widget being defective is 0.021. Find th

gavmur [86]

Answer:

$\=x=2.1$

$\sigma=2.03$

Step-by-step explanation:

From the question we are told that:

Sample size $n=100$

Probability of a defective widget $P=0.021$

Generally the equation for binomial trial is mathematically given by

$q=1-p$

$q=1-0.021$

$q=0.979$

Since X is binomial random variable with functions of n and p,The equation of mean \=x

$\=x=E(x)$

Where

$E(x=n*p)$

$\=x=100*0.021$

$\=x=2.1$

Generally the equation for variance \sigma is mathematically given by

$\sigma=\sqrt{nqp}$

$\sigma=\sqrt{200*0.021*0.979}$

$\sigma=2.03$
