8 0

Answer:

Height = 8

Step-by-step explanation:

Volume = Length x width x height

192 = 6 x 4 x H

192 = 24 x H

192/24 = H

8 = H

Height = 8

The formula for the area of a triangle is A=bh/2. The area of a triangle is 26 cm squared and its base is 12cm. Using algrebra,

Fed [463]

Answer:

4 and 1 / 3 cm

Step-by-step explanation:

Consider the following;

$A = 1 / 2 * Base * Height,\\26 cm^2 = 1 / 2 * ( 12 cm ) * Height$

Let us say that Height = x. If that is so, through algebra, let us solve for x;

$26 cm^2 = 1 / 2 * ( 12 cm ) * x,\\26 cm^2 = 6 cm * x,\\26 cm^2 / 6 cm = x,\\\\x = 26 cm^2 / 6 cm,\\x = 4 and 1 / 3\\\\Conclusion, Height = 4 and 1 / 3 ( cm )$

Solution ⇒ 4 and 1 / 3 cm

The boys had 5 4 6 gallons of water to share throughout the day. James drank 1 1 3 5 6 1 2 gallons and Simon drank 2 3 gallon. H

dsp73

Answer:

$1\frac{1}{3}$

Step-by-step explanation:

Total Volume of Water = $5\frac{4}{6}$

Volume drunk by James = $1\frac{1}{3}$

Volume drunk by Simon = $\frac{2}{3}$

Volume drunk by Matthew = $1\frac{1}{2}$

Volume drunk by Gilbert = $\frac{5}{6}$

Total Volume Drunk (i.e. The Sum) = $1\frac{1}{3} + \frac{2}{3} + 1\frac{1}{2} +\frac{5}{6}=\frac{13}{3}$

Volume of water Left = Total Volume of Water-Total Volume Drunk

= $5\frac{4}{6}-\frac{13}{3} =\frac{4}{3}=1\frac{1}{3}$

At a university, 60% of the 7,400 students are female. The student newspaper reports the results of a survey of a random sample

omeli [17]

Given Information:

Population mean = p = 60% = 0.60

Population size = N = 7400

Sample size = n = 50

Required Information:

Sample mean = μ = ?

standard deviation = σ = ?

Answer:

Sample mean = μ = 0.60

standard deviation = σ = 0.069

Step-by-step explanation:

We know from the central limit theorem, the sampling distribution is approximately normal as long as the expected number of successes and failures are equal or greater than 10

np ≥ 10

50*0.60 ≥ 10

30 ≥ 10 (satisfied)

n(1 - p) ≥ 10

50(1 - 0.60) ≥ 10

50(0.40) ≥ 10

20 ≥ 10 (satisfied)

The mean of the sampling distribution will be same as population mean that is

Sample mean = p = μ = 0.60

The standard deviation for this sampling distribution is given by

$\sigma = \sqrt{\frac{p(1-p)}{n} }$

Where p is the population mean that is proportion of female students and n is the sample size.

$\sigma = \sqrt{\frac{0.60(1-0.60)}{50} }\\\\\sigma = \sqrt{\frac{0.60(0.40)}{50} }\\\\\sigma = \sqrt{\frac{0.24}{50} }\\\\\sigma = \sqrt{0.0048} }\\\\\sigma = 0.069$

Therefore, the standard deviation of the sampling distribution is 0.069.
