Apples lose 75% of their weight during drying. How many pounds of fresh apples do you need to pick in order to get 150 lb of dri

Anna35 [415]

Since apples lose 75% of their weight, that means 150 lbs = 25% of fresh apples. 25% = 1/4, so the equation is 150/(1/4) = 150*4 = 600 lbs

If f(x) = 2(x)^2+5 sqrt (x-2). complete the following statement. f(2)=_____

dangina [55]

Answer:

The value of function at x = 2 is 8.

Step-by-step explanation:

Given : Function $f(x)=2x^2+5\sqrt{x-2}$

We have to find the value of given function at x = 2 , that is f(2)

Consider the given function $f(x)=2x^2+5\sqrt{x-2}$

To find the value f(2) put x = 2 in given function ,

We have,

$f(2)=2(2)^2+5\sqrt{2-2}$

Simplify, we have,

$f(2)=8+5\sqrt{0}$

Simplify further, we have,

$f(2)=8$

Thus, the value of function at x = 2 is 8.

Ms. McCormick keeps a rectangular recycling bin for used paper in her classroom. The area of the bottom of the bin is 400 square

aniked [119]

According to the dimensions given, the volume of paper in the recycling bin is of 6800 cubic inches.

<h3>What is the volume of a rectangular prism?</h3>

It is given by the multiplication of the base area by the height, that is:

$V = S_bh$

In this problem, we have that the measures in square inches and inches, respectively, are given by:

$S_b = 400, h = 17$

Hence:

$V = 400 \times 17 = 6800$

The volume of paper in the recycling bin is of 6800 cubic inches.

A manufacturing process makes rods that vary slightly in length but follow a normal distribution with mean length 25 cm and stan

Galina-37 [17]

Answer:

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22) = 0.1251

Step-by-step explanation:

Step(i):-

Given mean of the Population = 25cm

Given standard deviation of the Population = 2.60

Let 'x' be the random variable in normal distribution

Given x=22

$Z = \frac{x-mean }{S.D} = \frac{22-25}{2.60} = -1.15$

Step(ii):-

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22) = P( Z<-1.15)

= 1-P(Z>1.15)

= 1-( 0.5+A(1.15)

= 0.5 - A(1.15)

= 0.5 - 0.3749

= 0.1251

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22) = 0.1251

Are women better at multitasking than men? Researchers conducted a multitasking experiment in which 120 men and 120 women played

stich3 [128]

Answer:

Yes, women better at multitasking than men.

Step-by-step explanation:

Given

$n_1=120$ --- Men

$n_2=120$ --- Women

$\bar x_2 > \bar x_1$ --- Women with greater average speed

Required

Does women better at multitasking?

When making comparison between two variables that are subjected to the same conditions;

If both variables have different mean values; the variable with the greater mean value performs better.

So, in this case:

$\bar x_2 > \bar x_1$ means that women perform better than men, at multitasking.
