Answer: C. There are four groups of three tens and six ones

Step-by-step explanation:

From the options,

A. Three groups each have three tens and 4 ones.

Three tens and 4 ones equal: = (3 × 10) + (4 × 1) = 30 + 4 = 34

Therefore, 34 ÷ 3 is incorrect.

B. There are three groups of five tens and 9 ones in each group.

Five tens and 9 ones will be equal to:

= (5 × 10) + (9 × 1)

= 50 + 9 = 59

Therefore, 59 ÷ 3 is incorrect

C. There are four groups of three tens and six ones.

Three tens and six ones equal:

= (3 × 10) + (6 × 1)

= 30 + 6 = 36

Therefore, 36 ÷ 4 is correct

D. There are three groups of five tens and nine ones in each group.

Five tens and nine ones will be equal to:

= (5 × 10) + (9 × 1)

= 50 + 9 = 59

Therefore, 59 ÷ 3 is incorrect

Therefore, the correct option is C.

Normal Distribution Problem. Porphyrin is a pigment in blood protoplasm and other body fluids that is significant in body energy
GarryVolchara [31]

Answer: a) 0.9332, b) 0.8944

Step-by-step explanation: the probability value attached to a z score is gotten by using a z distribution table.

The z score is gotten by making use of the formulae below

Z = x - u / σ

Where x = sample mean, u = population mean and σ = population standard deviation.

a)

For our question, u = 38, σ = 12, we are to look for the z score at z ≤ 56, that's x = 56

By substituting the parameters, we have that

z ≤ 56 = 56 - 38/ 12

z ≤ 56 = 18/12

z ≤ 56 = 1.5

To get the probabilistic value, we check the normal distribution table.

The table I'm using will be giving me probabilistic value towards the left of the area.

From the table, p ( z ≤ 56) = 0.9332.

b)

Z >23 = 23 - 38/ 12

Z >23 = - 15/ 12

Z >23 = - 1.25

The probability value of this z score is towards the right of the distribution but the table I'm using is only giving probability values towards the left.

Hence Z >23 = 1 - Z<23

From the table, Z<23 = 0.1056.

Z >23 = 1 - 0.1056

Z >23 = 0.8944

Find the value of the length x rounded to 1 DP.
ivanzaharov [21]

Answer:

x = 13.6 cm

Step-by-step explanation:

part A:

using tan rule:

tan(x) = \frac{opposite}{adjacent}

tan(39) = \frac{6}{adjacent}

adjacent = \frac{6}{tan(39)}

adjacent = 7.41

part B:

using tan rule:

tan(x) = \frac{opposite}{adjacent}

tan(44) = \frac{6}{adjacent}

adjacent = 6.213

Total length of x:

part A + part B

7.41 + 6.213

13.6 cm

A cistern is leaking 0.25 liters of water per minute. Approximately how many gallons of water is the cistern losing per hour? (P
nikklg [1K]

The cistern is losing approximately 3.963 gallons of water per hour.

<u><em>Explanation</em></u>

A cistern is leaking 0.25 liters of water per minute.

<u>We know, 1 gallon = 3.785 liters</u>

So, 0.25 liters = \frac{0.25}{3.785}=0.06605... gallons

That means, the cistern is losing 0.06605....gallons of water per minute.

So, the amount of water losing in 1 hour or 60 minutes =(0.06605...*60) gallons= 3.963 gallons <em>(Approximately)</em>
