Fill in the missing information. Tim Worker is doing his budget. He discovers that the average miscellaneous expense is $45.00 w
nlexa [21]

Answer:

P(38.6

And we can assume a normal distribution and then we can solve the problem with the z score formula given by:

z=\frac{X -\mu}{\sigma}

And replacing we got:

z=\frac{38.6- 45}{16}= -0.4

z=\frac{57.8- 45}{16}= 0.8

We can find the probability of interest using the normal standard table and with the following difference:

P(-0.4

Step-by-step explanation:

Let X the random variable who represent the expense and we assume the following parameters:

\mu = 45, \sigma 16

And for this case we want to find the percent of his expense between 38.6 and 57.8 so we want this probability:

P(38.6

And we can assume a normal distribution and then we can solve the problem with the z score formula given by:

z=\frac{X -\mu}{\sigma}

And replacing we got:

z=\frac{38.6- 45}{16}= -0.4

z=\frac{57.8- 45}{16}= 0.8

We can find the probability of interest using the normal standard table and with the following difference:

P(-0.4

Find the answer. Number 1,2,3,4,5, and 6.
jeyben [28]

Answer:

<u><em>Note. All numbers are rounded to the nearest tenth</em></u>

1

  • x/9 = cos 48°
  • x = 9 cos 48°
  • x = 6.0

2.

  • x/11 = sin62°
  • x = 11 sin 62°
  • x = 9.7

3.

  • x/8 = tan 75
  • x = 8 tan 75°
  • x = 29.9

4.

  • sin x = 38/53
  • x = arcsin 38.53
  • x = 45.8°

5.

  • tan x = 15/20
  • x = arctan 15/20
  • x = 36.9°

6.

  • cos x = 27/29
  • x = arccos 27/29
  • x = 21.4°
