Answer:

35 gallons of mulch will cover 7 flowerbeds

Step-by-step explanation:

If it takes 15 gallons of mulch to cover 5 flowerbeds then we can represent the number of gallons per flowerbed.

The number of gallons per flowerbed = 15 gallons of mulch /5 flowerbeds

= 3 gallons of mulch/ flowerbeds

So it takes 3 gallons of mulch to cover 1 flowerbed.

Therefore for 7 flowerbeds we can determine the amount of gallons of mulch needed by using conversion factors:

= (3 gallons of mulch/ flower bed)×7 flowerbeds

= 21 gallons of mulch

Therefore 21 gallons of mulch will cover 7 flowerbeds

You need to work out how much you need for 1 flowerbed,
So, 15÷5= 3. 3 gallons =1 flowerbed
Then, 3 X 7 = 21 Gallons.

What is the value of the remainder if 10x4 – 6x3 + 5x2 – x + 1 is divided by x – 3?

natita [175]

Answer:

Remainder is 691.

Step-by-step explanation:

Given function is $10x^4-6x^3+5x^2-x+1$ .

Now we need to find remainder if we divide given function $10x^4-6x^3+5x^2-x+1$ by (x-3)

(x-3) means plug x=3 into $10x^4-6x^3+5x^2-x+1$ to find remainder.

$10x^4-6x^3+5x^2-x+1$

$=10(3)^4-6(3)^3+5(3)^2-(3)+1$

$=10(81)-6(27)+5(9)-(3)+1$

$=810-162+45-3+1$

$=856-162-3$

$=856-165$

$=691$

Hence remainder is 691.

Find the mean and standard deviation for the set of data.

dem82 [27]

The mean and standard deviation for the set of data will be 16 and 5.87. Then the correct option is A.

<h3>What is a standard deviation?</h3>

It is the measure of the dispersion of statistical data. Dispersion is the extent to which the value is in a variation.

The set of data is given below.

16, 22, 8, 5, 20, 18, 14, 17, 24

The mean of the data set will be

μ = (16 + 22 + 8 + 5 + 20 + 18 + 14 + 17 + 24) / 9

μ = 144 / 9

μ = 16

Then the standard deviation of the data set will be

$\rm \sigma = \sqrt{\dfrac{\Sigma (x_i - \mu)^2}{n}} \\\sigma = \sqrt{\dfrac{(16 - 16)^2 +(22 - 16)^2 + (8-16)^2 + ......+(24-16)^2 }{9}} \\\sigma = \sqrt{\dfrac{310}{9}}\\$

Simplify the expression further, then we have

σ = √34.44

σ = 5.87

The mean and standard deviation for the set of data will be 16 and 5.87.

Then the correct option is A.
