Change the fraction 3/4 to a percent
Rom4ik [11]
To convert 3/4 to a percent we need to convert 3/4 to a decimal and then multiply the decimal by 100. Lets do it:-

To convert a fraction to a decimal we have to divide the numerator by the denominator.

3/4  
3 ÷ 4 = 0.75

Decimal = 0.75

0.75 × 100 = 75
75%.

So, 3/4 in percent form is 75%.

Hope I helped ya!! xD

If the sampled population has a mean of 48 and standard deviation of 16, then the mean and the standard deviation for the sampli
Step2247 [10]

Answer:

48 and 4

Step-by-step explanation:

If we assume that \bar X to be the random variable that proceed the normal distribution with mean \mu and  a standard deviation \dfrac{\sigma }{\sqrt{n}}

Given that:

mean =48

standard deviation = 16

sample size = 16

The population mean is same as the population mean in sampling distribution that is 48.

The standard deviation of the sampling distribution is therefore calculated as:

standard deviation = \dfrac{\sigma }{\sqrt{n}}

standard deviation = \dfrac{16 }{\sqrt{16}}

standard deviation = \frac{16}{4}

standard deviation = 4

Thus; the mean and the standard deviation of the sampling distribution is 48 and 4

One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg ha
anastassius [24]
Solutions

To solve this problem we have to use the Pythagorean theorem. You can only use the Pythagorean theorem in Right Triangles. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c². 

Given 

One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg has a length of 10x yards.

First leg (24 yards) would be α 

Second leg would be β

Hypotenuse (74 yards) would be c

Now we have points α β c.  

a² (24) + β² ( x ) = c² (74) 

Calculations 

c² = α² + β²

74² = 24²+ β² 

<span>5476 = 576 + </span>β² 

5476 - 576 = β²
<span> </span>
<span>4900 = </span>β² 

→√4900 
<span> </span>
β<span> = 70 yards 
</span>
<span>70 = 10x 
</span>
<span>x = 70</span>÷<span>10 = 7 yards  
</span>
The second leg = 7 yards

Find the number if 1 2/3% of it is 4.75
Alecsey [184]
<h2>Answer:</h2>

The number is:

                      285

<h2>Step-by-step explanation:</h2>

It is given that:

1 2/3% of a number is 4.75.

Let the number be x.

We know that:

1\dfrac{2}{3}=\dfrac{1\times 3+2}{3}=\dfrac{5}{3}

This means that:

\dfrac{5}{3}\%\ of\ x=4.75

i.e.

\dfrac{5}{3\times 100}\times x=4.75\\\\\dfrac{1}{60}\times x=4.75\\\\x=4.75\times 60\\\\x=285

Hence, the number is: 285
