Answer:

The standard deviation is above 6 mm, which means that this batch does not pass the technical control.

Step-by-step explanation:

Mean of the batch:

The mean of the batch is the sum of all values divided by the number of items. So

M = \frac{31+32+38+34+45+41+24}{7} = 35

Mean in the desired interval.

Standard deviation:

Square root of the sum of the difference squared between each term and the mean, divided by the number of itens. So

S = \sqrt{\frac{(31-35)^2+(32-35)^2+(38-35)^2+(34-35)^2+(45-35)^2+(41-35)^2+(24-35)^2}{7}} = 6.46

The standard deviation is above 6 mm, which means that this batch does not pass the technical control.

Consider two events, P and Q. The probability of event P occurring is 16. The probability of event Q occurring is 23. Which stat
garri49 [273]

The event "P and Q" is a compound event in the probability, and the true statement about the probability is P(P and Q) = 1/9

<h3>How to determine the true statement?</h3>

The probabilities are given as:

P(P) = 1/6

P(Q) = 2/3

The probability of the event P and Q is calculated using:

P(P and Q) = P(P) * P(Q)

This gives

P(P and Q) = 1/6 * 2/3

Evaluate the product

P(P and Q) = 1/9

Hence, the true statement about the probability is P(P and Q) = 1/9

Write a power represented with a positive base and a positive exponent whose value is less than the base
dlinn [17]

You have that situation with ANY base that's less than ' 1 '.

Examples:

(0.9)² = 0.81  (90% of the base)

(7/8)² = 0.765625  (87.5% of the base)

(1/2)² = 1/4  (50% of the base)

(0.1)² = 0.01  (10% of the base)

Each of these results is less than the base, and with
higher positive powers, they keep getting smaller.

Use proportion to find the whole 75 is 15% of what number
Iteru [2.4K]

Answer:

500

Step-by-step explanation:

15% * x = 75

(15/100) * x = 75           Multiply both sides by 100/15

(15/100)*(100/15) = 75 * 100/15

x = 7500/15

x = 500

Answer 500

Proportion

15/100 = 75 / x             Cross multiply

15x = 100*75                Combine the right

15x = 7500                   Divide 15

15x/15 = 7500/15

x = 500

At an amusement park , the cost of 3 adult tickets and 4 children’s ticket is $126.50 another customer paid $120.50 for 2 adult
KonstantinChe [14]

Answer:

1 Adult ticket=$21.50 ; 1 Children ticket=$15.50

Step-by-step explanation:

3A+4C=126.50

2A+5C=120.50

We find the price of adult tickets 1st.

15A+20C=632.5

8A+20C=482

7A=632.5-482=150.5

1A=21.50

Now we find Children ticket

6A+8C=253

6A+15C=361.50

7C=108.50

1C=15.50
