Tanzania [10]

The statement that correctly describes the product, 5.15 x 6√7, which is 81.7537155..., is <u>A. </u><u>irrational</u>.

<h3>What is an irrational product?</h3>

An irrational number is one that can be written as a decimal, but not as a fraction.

An irrational number has endless non-repeating digits to the right of the decimal point.

The rules for determining if a product is rational or irrational are as follows:

The product of two rational numbers is rational.
The product of a rational number and an irrational number is irrational.
The product of two irrational numbers is irrational.

<h3>Data and Calculations:</h3>

5.15 x 6√7

= 5.15 x 6 x 2.64575...

= 81.7537155...

Thus, the product of 5.15 x 6√7 is irrational because √7 is irrational.

<em /> $\displaystyle 3^{6x + 18} < 27^{3x}$ <em />

<em />

<u>Step 2: Solve for </u><em><u>x</u></em>

Rewrite: $\displaystyle 3^{6x + 18} < 3^{3(3x)}$
Set: $\displaystyle 6x + 18 < 3(3x)$
Factor: $\displaystyle 3(2x + 6) < 3(3x)$
[Division Property of Equality] Divide 3 on both sides: $\displaystyle 2x + 6 < 3x$
[Subtraction Property of Equality] Subtract 3x on both sides: $\displaystyle -x + 6 < 0$
[Subtraction Property of Equality] Subtract 6 on both sides: $\displaystyle -x < -6$
[Division Property of Equality] Divide -1 on both sides: $\displaystyle x > 6$

The length of human pregnancies varies normally with a mean of 266 days and a standard deviation of 16 days.What is the median l

docker41 [41]

Answer:

The median length of all pregnancies will be 266 days.

Step-by-step explanation:

We have been given that the length of human pregnancies varies normally with a mean of 266 days and a standard deviation of 16 days. We are asked to find the median length of all pregnancies.

We know that mean, median and mode all are equal for normal distribution.

Since we are told that the length of human pregnancies varies normally, therefore, the median length of all pregnancies will be same as mean that is 266 days.
