Answer:

(a) Minimum red blood cells 5.744 million cells per micro liter

(b) Maximum red blood cells 5.068 million cells per micro liter.

Step-by-step explanation:

Z-score formula is = \frac{x-u}{Standard deviation}

Z-score = \frac{x-5.5}{0.4}

The value of z-score is 0.61 so then x will be;

x = 5.744

The minimum red blood cells count that can in top is 27% of count which is 5.744 million cells per micro liter.

Z-score = \frac{x-5.5}{0.4}

The value of z-score is 0.14 so then x will be;

x = 5.068

The maximum red blood cells count that can be in top is 14% of count which is 5.068 million cells per micro liter.

question 14(multiple choice worth 5 points) (01.07 lc) what is the product of 3.4 × 10−14 and 1.8 × 1028? 6.12 × 1014 9.4 × 1014
asambeis [7]

The product of (3.4 × 10⁻¹⁴) and (1.8 × 10²⁸) is 6.12 × 10¹⁴. Applying associative property and exponential rule, the required product is calculated.

<h3>What are the required properties?</h3>

The given products are decimals and exponentials. So, the required properties are the associative and exponential rules. They are as follows:

Associative property:

a×(b × c) = (a × b)×c

From this, we can also write,

(a × b) × (c × d) = (a × c) × (b × d)

Exponential rule:

The product of two exponentials is a^m\times a^n = a^{m+n}

<h3>Calculation:</h3>

The given values are

3.4 × 10⁻¹⁴ and 1.8 × 10²⁸

The product of these values is

(3.4 × 10⁻¹⁴) × (1.8 × 10²⁸)

Applying the associative property: (a × b) × (c × d) = (a × c) × (b × d);

⇒ (3.4 × 10⁻¹⁴) × (1.8 × 10²⁸) = (3.4 × 1.8) × (10⁻¹⁴ × 10²⁸)

Applying exponential rule: a^m\times a^n = a^{m+n}

⇒ 6.12 × 10⁻¹⁴⁺²⁸

⇒ 6.12 × 10¹⁴

Thus, the product of the given values is 6.12 × 10¹⁴. Option A is correct.

Llana [10]
N+(n+1)= 57

Combine like terms
2n+1=57

Subtract 1 from both sides
2n=56

Divide both sides by 2
n=28

Help it’s 6 grade math

Answer:

the mean is 55.6; if she redid the D and F papers the mean would increase because you would get a higher average than before. Higher scores mean that the number that you add are larger evidently ending up in a larger value

Step-by-step explanation:

if you want to find mean, all you do is add the numbers together and then divide by the total number of values that you added.

so this would be 74+12+61+86+45 and that is 278. Then there is a total of 5 so you divide 278 by 5 which gives you 55.6.
