Answer:

x = 15

Step-by-step explanation:

the figure has one pair of parallel sides and is therefore a trapezoid.

the lower base angle is supplementary to the upper base angle on the same side, then

8x + 6 + 54 = 180

8x + 60 = 180 ( subtract 60 from both sides )

8x = 120 ( divide both sides by 8 )

x = 15

kumpel [21]

Answer:

$V_f=450ml/hr$

Step-by-step explanation:

From the question we are told that:

Mass $m=15kg$

Amount of NaCl IV $n=0.9\%$

Rate $R=30ml/kg/hr$

Generally the equation for fluid rate be for your IV pump is mathematically given by

$V_f=mR$

Since

Rate is

30ml/kg/hr at 1kg patient Weight

Therefore

$V_f=15*30$

$V_f=450ml/hr$

Answer:

The mean is 40.35 and the standard deviation is 0.13.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a certain type of olivine assembly, the silicon dioxide (SiO2) content (in weight percent) in a randomly chosen rock has mean 40.35 and standard deviation 0.4.

Sample of 10:

By the Central Limit Theorem, the mean is 40.35, and the standard deviation is $s = \frac{\sigma}{\sqrt{n}} = \frac{0.4}{\sqrt{10}} = 0.13$

The mean is 40.35 and the standard deviation is 0.13.

if u wanted to find the depth of a submarine during a dive , would it be more reasonable to use an equation with the rate in fee

sergij07 [2.7K]

I would choose to use the equation with feet per hour. Submarines reach such great depths that I feel this unit of measurements better represents the magnitude of those depths.

X+9=24 how to solve for x

rodikova [14]

You can easily do just one step to get the value of x.

x + 9 =24 subtract 9 from both sides

x + 9 - 9 = 24 - 9

Simplify:

x = 15

I hope I helped you.
