The smallest sample size that will satisfy the conditions for the use of a normal model to represent the sampling distribution is 30, as stated in option (a).
The smallest sample size that will satisfy the conditions for the use of a normal model to represent the sampling distribution is determined by the Central Limit Theorem, which states that if the sample size is greater than or equal to 30, the sampling distribution of the sample mean will be approximately normal, regardless of the shape of the population distribution.
According to this theorem, if the sample size is greater than or equal to 30, the sampling distribution of the sample mean will be approximately normal, regardless of the shape of the population distribution. Therefore, the smallest sample size that will satisfy the conditions for the use of a normal model is 30. The answer is therefore option (a).

What is the measure of \angle 1?, What is the measure of \angle 2?, What is the measure of \angle 4? and What is the measure of \angle 5?
Answer:
<1 and <6 = 98
<2 and <3 = 139
<4 and <5 = 123
Step-by-step explanation:
82 + 9x - 6 + 6x - 1 = 180
15x + 75 = 180
15x = 105
x = 7
<1:
x + 82 = 180
x = 98
<2:
6x - 1 = 6(7) - 1 = 41
x + 41 = 180
x = 139
<3 = <2 because of vertical angle thm so <3 = 139
<5:
9x - 6 = 9(7) - 6 = 57
x + 57 = 180
x = 123
<4 = 5 because of vertical angle thm
<6 = <1 because of vertical angle thm

Mary was allowed a discount of 11% for goods worth sh.8000 and a discount of 8.6% for goods worth sh.17000. What percentage discount was she allowed altogether
Mary got 9.37%. discount .
What is percentage discount?A percentage discount is a reduction in the price of a good or service that is expressed as a number of hundred. A 20 percent reduction, for instance, would result in an item that was originally $100 costing $80.Given ,
discount = 11%
So,
((8000x0.110) + (17000x0.086)) = 2342
⇒ 2342 / (8000+17000) = 2342/25000
= 0.0937 or 9.37% discount.
The percentage discount allowed all together was 9.37%.

B) Three two-digit integers have a mean average of 16 and a range of 16. The median of the integers is 12. If all three integers are even and all are different to each other, what are the 3 numbers?
Answer:
The three numbers are 10,12 and 26
Step-by-step explanation:
For the average of the numbers to be 16; it means that the sum of all the numbers will be:
3 * 16 = 48
If the median is 12, it means the middle number is 12
For the range to be 16, the difference between the highest and smallest number is 16
if the lowest is x, then the highest will be (x + 16)
So, if we added these and 12, we get 48
Thus;
(x + 16) + x + 12 = 48
2x + 28 = 48
2x = 48-28
2x = 20
x = 20/2
x = 10
Then, the last number will be x + 16 = 10 + 16 = 26
So, the three numbers are 10,12 and 26

The isosceles triangle shown has a base of 4 y + 2 and a perimeter of 6 y + 12 . Which expression represents the length of 1 of the triangle's legs?
Answer:
The expression that represents the length of 1 of the triangle's legs is y + 5
Step-by-step explanation:
An isosceles triangle has two sides equal which are the triangle legs. Let b represent the base of the triangle and l represent one of the triangle's legs. Then, the perimeter, P is given by
P = l + l + b
i.e P = 2l + b
From the question, P = 6y + 12 and b = 4y +2
∴ 6y + 12 = 2l + 4y + 2
6y - 4y + 12 - 2 = 2l
2y + 10 = 2l
∴ 2l = 2y + 10
Then,
l = (2y+10)/2
l = y + 5
Hence, the expression that represents the length of 1 of the triangle's legs is y + 5
Two numbers decomposed into prime factors are expressed as follows: 2³. 3. 5 is 2². 3².7 Indicate the number of prime factors Which represents the least common multiple of these numbers
Answer:
2³. 3². 5. 7
Step-by-step explanation:
Since the first number is 2³. 3. 5 and the second number is 2². 3².7, we multiply the prime number with the highest exponents.
Since 2³. 3. 5 = 2³. 3¹. 5¹. 7⁰ and 2². 3².7 = 2². 3². 5⁰. 7¹ ,we multiply the prime number with the highest powers to get the least common multiple of both numbers, so, we have the L.C.M = 2³. 3². 5¹. 7¹ = 2³. 3². 5. 7

Daphne played 240 consecutive games of soccer without being taken off the field. Then, after a single game on the sidelines, she played another string of consecutive games, although this string was 40% shorter. How many consecutive games was that?
Answer:
144.
Step-by-step explanation:
40% shorter means she played 100 - 40 = 60% of the previous tall.
60% of 240
= 240 * 0.6
= 144 games.
