hapis has four buckets. The buckets hold 4700ml,4.8l,3880ml,and 4.71 l hapis wants to to use the bucket that holds the closest t

Mariana [72]

Answer:

Bucket 2

Step-by-step explanation:

Bucket 1 = 4700ml

Bucket 2 = 4.8l

Bucket 3 = 3880ml

Bucket 4 = 4.71 l

Convert holding capacity of bucket 1 and bucket 3 into liters

1 liter = 1000 milliliter

Bucket 1 = 4700ml

4700ml = 4.7l

Bucket 3 = 3880ml

3880ml = 3.88l

Therefore,

Bucket 1 = 4.7l

Bucket 2 = 4.8l

Bucket 3 = 3.88l

Bucket 4 = 4.71 l

The bucket closest to 5liters is bucket 2 with a holding capacity of 4.8 liters

A store sells flower arrangements at a cost of $28 each. Which statements are true regarding the price of the arrangements? Chec

Maru [420]

Let's check each case to determine the solution to the problem.

we know that

The cost of each flower arrangements is $\$28$

Statements

case A) If the price is marked down by $10$ percent, the new price will be $\$25.20$

we know that

If the price is marked down by $10$ percent

then

the new price will be

$10\%= \frac{10}{100} =0.10$

$(1-0.10)*\$28=0.90*\$28 \\= \$25.20$

$\$25.20=\$25.20$

therefore

The statement case A) is True

case B) If the price is marked down by $25$ percent, the new price will be $\$21$

we know that

If the price is marked down by $25$ percent

then

the new price will be

$25\%= \frac{25}{100} =0.25$

$(1-0.25)*\$28=0.75*\$28 \\= \$21$

$\$21=\$21$

therefore

The statement case B) is True

case C) If the price is marked down by $50$ percent, the new price will be $\$19$

we know that

If the price is marked down by $50$ percent

then

the new price will be

$50\%= \frac{50}{100} =0.50$

$(1-0.50)*\$28=0.50*\$28 \\= \$14$

$\$14 \neq \$19$

therefore

The statement case C) is False

case D) If the price is marked down by $35$ percent, the new price will be $\$18.20$

we know that

If the price is marked down by $35$ percent

then

the new price will be

$35\%= \frac{35}{100} =0.35$

$(1-0.35)*\$28=0.65*\$28 \\= \$18.20$

$\$18.20=\$18.20$

therefore

The statement case D) is True

case E) If the price is marked down by $40$ percent, the new price will be $\$29.80$

we know that

If the price is marked down by $40$ percent

then

the new price will be

$40\%= \frac{40}{100} =0.40$

$(1-0.40)*\$28=0.60*\$28 \\= \$16.80$

$\$16.80 \neq \$29.80$

therefore

The statement case E) is False

A random sample of five Galaxy 8 smartphones is selected from the production line after final assembly, and the result of the we

Dmitrij [34]

Answer:

a. Mean = 155.1 grams

b. Standard deviation = 0.37

c. Fractional uncertainty = 0.074

Step-by-step explanation:

a. Average weight

This is same as the mean weight;

Mathematically, that would be; sum of the weights/ the number of weights

= (155.1 + 154.8 + 155.5 + 155.3 + 154.6)/5 = 775.3/5 = 155.06 which is approximately 155.1

b. Standard deviation

Mathematically; we calculate that using the formula;

√{(x-mean)^2/(N-1)}

Please check attachment for for the complete breakdown of this

c. Fractional uncertainty

= Standard deviation/number of measurements = 0.37/5 = 0.074
