Answer:

The number of units decreased by $8.7\%$ .

Step-by-step explanation:

Initially, 470 units were sold. The following 429 units were sold, meaning this was $470-429=41$ less units than last year. Thus, the number of units sold decreased and the percent of decrease is:

$\frac{41}{470}\approx 8.7\%$

Need help solving for relative frequency please!

Sunny_sXe [5.5K]

Answer:

Kindly check explanation

Step-by-step explanation:

Given :

Relative frequency = frequency / total frequency

Total frequency = 389+335+975+351+72 = 2122

Response ________ Frequency __ R/ frequency

Never ____________ 389 _ 389/2122 = 0.180

Rarely ____________ 335 _ 335/2122 = 0.158

Sometimes _________975 _975/2122 = 0.459

Most of the time _____ 351 _ 351/2122 = 0.165

Always ____________ 72 __ 72/2122 = 0.034

I need this done super fast help!!!! And it has 7 parts so step by step please

Answer:

177 and 178

Step-by-step explanation:

First, the expression for the 2nd mile marker is x+1.

Now, you add x and x + 1 together to get 2x + 1

Next, make 2x + 1 equal to 355

Now subtract 1 and then divide by two on both sides to get x = 177.

This means that the first mile marker is 177 and the next is 178.

Kisachek [45]

Answer:

A. 14x14x28

B. The maximum volume is 5488 cuibic inches

Step-by-step explanation:

The problem states that the box has square ends, so you can express volume with:

$v=x^{2} y$

Using the restriction stated in the problem to get another equation you can substitute in the one above:

$4x+y=84\\\\$

Substituting y whit this equation gives:

$v=x^{2} (84-4x)\\\\v=84x^{2} -4x^{3}$

Now find the limit of x:

$\frac{84x^{2}-4x^{3}}{dx}=168x-12x^{2}\\\\x=\frac{168}{12}=14$

Find the length:

$y=84-4(14)=28$

You can now calculate the maximum volume:

$v=(14)^{2}(28)= 5488$

Evgesh-ka [11]

The total area under the curve must equal 1. Let the value of the density curve be x. Then 10x = 1. Therefore x = 1/10 or 0.1.
The correct answer is D. 0.1.
