Alborosie

Answer:

Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M will be approximately normal.

Step-by-step explanation:

We use the central limit theorem to solve this question.

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a sample size larger than 30 can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$

Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M will be approximately normal.

The rectangle shown has a perimeter of 86 cm and the given area. Its length is 7 more than five times its width. Write and

Sati [7]

Answer: the length of the rectangle is 37ft

the width of the rectangle is 6 ft

Step-by-step explanation:

Let L represent the length of the rectangle.

Let W represent the width of the rectangle.

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

The perimeter of the given rectangle is 86 feet. This means that

2(L + W) = 86

Dividing through by 2, it becomes

L + W = 43 - - - - - - - - - - - -1

Its length is 7 more than five times its width.. This means that

L = 5W + 7

Substituting L = 5W + 7 into equation 1, it becomes

5W + 7 + W = 43

6W + 7 = 43

6W = 43 - 7

6W = 36

W = 36/6

W = 6

L = 5W + 7 = 5 × 6 + 7

L = 37

The price of a computer was decreased by 20% to £136. What was the price before the decrease?

Contact [7]

Answer:

£ 170 .

Step by step explanation :

Given that the price of a computer was decreased by 20% to £136. And we need to find the Original price before the decrease. So , let the earlier price be x ,

Decrease in 20 % :-

⇒ Decreased price = 20% of x

⇒ Decreased price = 20/100 × x

⇒ Decreased price = x/5

New price :-

⇒ New price = x - x/5

⇒ New price = 5x - x/5

⇒ New price = 4x/5.

But its given £ 136 , So

⇒ 4x/5 = £ 136

⇒ x = £ 136 * 5/4

⇒ x = £ 170

<h3>Hence the Original price was £ 170 .</h3>
