I am pretty sure that the main thing that we should do to solve this task is to do this : 5(0.75)+6(0.15)+7(0.10)3.75+0.9+0.7&#10;&#10;&#10;5.35 which is weighted average as it only can be found by adding <span>the products of each corresponding value. Hope everything is clear! Regards!</span>

Answer:

Weighted Average =  Σwx /  Σw = 5.35  / 1 = 5.35

Step-by-step explanation:

The Formula for calculating the Weighted Average of a data set is;

Weighted Average =  Σwx /  Σw

Where

Σwx - Is the sum of the product of each weight, and its value

Σw - Is the sum of each weight

In  this case,

Σwx = (5.00 * (75.0 / 100)) + (6.00 * (15.0 / 100)) + (7.00 * (10.0 / 100))

       = (5.00 * 0.75) + (6 * 0.15) + (7 * 0.10)

       = 3.75 + 0.90 + 0.70

       = 5.35

Σw   = (75.0 / 100) + (15.0 / 100) + (10.0 / 100)

       = 0.75 + 0.15 + 0.1

       = 1

Hence, Weighted Average =  Σwx /  Σw = 5.35  / 1 = 5.35

Select the correct answer.
slamgirl [31]

Answer:

The graphs are missing, but we can find the inequality for this problem:

She has $60.

The price of a T-shirt is $10, the price of a sweatshirt is $14.

If T is the number of T-shirts she buys, and S is the number of sweatshirts that she buys, we have:

T + S ≥ 5 (because she wants to buy at least 5 items)

T*$10 + S*$14 < $60 (because she wants to spend under $60)

Those two inequalities define the number of T-shirts and sweatshirts that she can buy.

Events M and N are independent events. In this scenario, if P(M) = 0.46 and P(M and N) = 0.138, then P(N) = .
Oksi-84 [34.3K]

Answer:

P(N)=0.3

Step-by-step explanation:

Given: P(M)= 0.46, P(M and N)=0.138

Using P(M) ×P(N)= P(M and N)

⇒0.46×P(N)= 0.138

⇒P(N)= \frac{0.138}{0.46}

⇒P(N)=0.3

yaroslaw [1]

Answer:

The statement provided is True.

Step-by-step explanation:

The exponential function representing growth is given as follows:

y=y_{0}\cdot e^{kt}

Here,

<em>y</em> = final value

<em>y</em>₀ = initial value

<em>k</em> = growth rate

<em>t</em> = time passed

As the function e^{x} is increasing, then the exponential function representing growth is also increasing.

Thus, the statement provided is True.
