Answer: The answer is Three whole and five sixths (3 5/6)

Step-by-step explanation: One whole and three fourths can be expressed as 1 3/4, and this is added to five sixths, that is, 5/6. therefore these can be expressed as

[1 3/4 + 5/6}

The other part of the questions says one whole and one fourth which can be expressed as 1 1/4.

The entire question can now be written out as

[1 3/4 + 5/6] + [1 1/4]

We would start by solving for the left hand side of the expression

1 3/4 + 5/6

= 7/4 +5/6

By using a common denominator which is 12 (the LCM), the expression now becomes,

[21 + 10]/12

= 31/12

We can now add this to the right hand side of the expression. Thus,

[31/12] + 1 1/4

=31/12 + 5/4

By using a common denominator which is also 12, the expression now becomes,

[31 + 15]/12

= 46/12, By simplifying further we arrive at,

23/6.

Written as a proper fraction, this becomes

3 5/6 (Three whole and five sixths)

Answer:

The correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by $\pi$

Option D is correct option.

Step-by-step explanation:

The circumference of table top = 24 $\pi$ inches

We need to find area of table top

The formula used to find area is: $Area = \pi r^2$

We need to find radius of tabletop.

The formula used to find circumference is: $Circumference = 2\pi r$

Putting value of circumference we can find radius

$Circumference = 2\pi r\\24\pi =2\pi r\\r=\frac{24\pi}{2\pi}\\r=12$

So, radius of table top = 12

Now, finding the area:

$Area = \pi r^2\\Area=\pi(12)^2\\Area=3.14(144)\\Area=452.16\:inches^2$

So, the correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by $\pi$

Option D is correct option.

Suppose x is a normally distributed random variable with a mean of 22 and a standard deviation of 5. The probability that x is l

MaRussiya [10]

Answer:

The probability that x is less than 9.7 is 0.0069 = 0.69%

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 22, \sigma = 5$
