I need to know how to solve for X

yulyashka [42]

add all the numbers until u left with no numbers left except the number left over and then add xs and then subtract the number from 23 to isolate x. then divide x by the number left over from the right side.

-6+9-19=-16

x+2x=3x

so -16+3x= 23

+16 +16

3x=39

(3/3)x=39/3

x=13

hope it helps!

Answer:

the lower value of the interval = 35.26

Step-by-step explanation:

The mean number is u = 40.1

n = 16

the mean number called x is 38.1

the standard deviation = 5.8

given a 95% Confidence Interval

The lower value of the confidence interval is?

<u>solution</u>

There is a inﬁnite population and the standard deviation of the population is known,

the below formula is used for determining an estimate of the conﬁdence limits of the population mean, i.e.

x ± ( zₐσ)/ √n

For a 95% conﬁdence level, the value of za is taken from the confidence interval table = 1.96.

the conﬁdence limits of the population=

x ± ( zₐσ)/ √n

38.1 ± (1.96*5.8)/ √16

38.1 ± 11.368/4

38.1 ± 2.842

40.942 or 35.258

Thus, the 95% conﬁdence limits are 40.942 or 35.258

this prediction is made with conﬁdence that it will be correct nine five times out of 100.

finally, the lower value of the interval = 35.26

Dimas [21]

Answer:

x = 225.16 feet

Step-by-step explanation:

Given that,

The angle between the piling and the pier is 60°.

A surveyor has set up his transit on one side of the lake 130 feet from a piling that is directly across from a pier on the other side of the lake.

We need to find the distance between the piling and the pier. Let the distance be d. Using the trigonometry to find it as follows :

$\tan(60)=\dfrac{x}{130}\\\\x=\tan(60)\times 130\\\\x=225.16\ feet$

So, the required distance is 225.16 feet.
