Marta_Voda [28]

Answer:

They have collected 375 cans of food.

Step-by-step explanation:

In conducting a canned-food drive,the goal of the school is to collect a total of 500 cans of food. They have reached 6/8 of their goal. This means that they have collected 6/8 of the total number of cans of food that they intended to collect. The number of cans of food that they have collected would be

6/8 × 500 = 375 cans of food.

Solve the attachment...

hichkok12 [17]

Answer:

2 ( Option A )

Step-by-step explanation:

The given integral to us is ,

$\longrightarrow \displaystyle \int_0^1 5x \sqrt{x}\ dx$

Here 5 is a constant so it can come out . So that,

$\longrightarrow \displaystyle I = 5 \int_0^1 x \sqrt{x}\ dx$

Now we can write √x as ,

$\longrightarrow I = \displaystyle 5 \int_0^1 x . x^{\frac{1}{2}} \ dx$

Simplify ,

$\longrightarrow I = 5 \displaystyle \int_0^1 x^{\frac{3}{2}}\ dx$

By Power rule , the integral of x^3/2 wrt x is , 2/5x^5/2 . Therefore ,

$\longrightarrow I = 5 \bigg( \dfrac{2}{5} x^{\frac{5}{2}} \bigg] ^1_0 \bigg)$

On simplifying we will get ,

$\longrightarrow \underline{\underline{ I = 2 }}$

In 2009, the American Time Use Survey found that the average American spends 2.8 hours a day watching TV. Suppose the standard d

Anit [1.1K]

Answer:

4.72 hours/day

Step-by-step explanation:

Mean time spent watching TV (μ) = 2.8 hours a day

Standard deviation (σ) = 1.5 hours a day

The 90th percentile (upper 10%) of a normal distribution has an equivalent z-score of roughly z = 1.282. The minimum time spent watching TV, X, at the 90th percentile is:

$z=\frac{X-\mu}{\sigma} \\1.282=\frac{X-2.8}{1.5}\\ X=4.72\ hours/day$

On a typical day, you must watch at least 4.72 hours of TV to be in the upper 10%.

Need help solving this problem

natka813 [3]

Answer:

Part 1: $\frac{11-x}{5}$ or $\frac{11}{5}-\frac{x}{5}$

Part 2: $\frac{9}{5}$

Step-by-step explanation:

To start things off, you must put everything on the opposite side of y so that you only have the y variable left.

In this case, put x onto the other side, making it negative since it's flipped, so you get $5y=11-x$ (since the x is negative you're using subtraction from 11).

Next, divide both sides by 5 to make 5y into y:

$\frac{5y}{5} =\frac{11}{5}-\frac{x}{5}$

$y=\frac{11}{5}-\frac{x}{5}$

Then in this case you turn y=f(x), but the system did it for you, so all you have to put is $\frac{11}{5}-\frac{x}{5}$ .

For the second part you must replace x with 2 since you need to find f(2).

$\frac{11-2}{5}$

Your answer for part 2 is $\frac{9}{5}$ .
