Answers

Answer:

Tia cut a 4-meter 8-centimeter wire into 10 equal pieces. for Jay 10 quarts would be the answer. Step-by-step explanation: He needs x quarts for the inside painting and x + 19 quarts for the outside. These two measures add up to 2x + 19, which equals 107 (quarts) total. The last one is tring A is 35 cm long, string B is 5 times as long as string A, then string B is 35·5=175 cm long. In total both strings have length 35+175=210 cm. The total length of string needed for 17 identical decirative bottes is  cm that is 35.7 m.

An investment earn 6% simple interest. What amount of principal is need to have $3000 after 5 years

Answers

Answer:

The amount of $1000 principal is needed to have $3000 after 5 years.

Step-by-step explanation:

As the interest formula is

[tex]I=Prt[/tex]

Where

P is the principler is the rate in decimalt is the time in years

Substituting the following values in the interest formula and solve for P

I=$3000

r = 6% = 6/100 = [tex]0.06[/tex]

t = 5

so the equation becomes

[tex]I=Prt[/tex]

[tex]3000=P\left(0.06\right)\left(5\right)[/tex]

switch both sides

[tex]P\left(0.06\right)\left(5\right)=3000[/tex]

[tex]P\left(0.3\right)=3000[/tex]

[tex]P=10000[/tex] $

Therefore, the amount of $1000 principal is needed to have $3000 after 5 years.

Alicia received the following seven scores on her math assignments.

80, 90, 10, 75, 90, 95, 99

Find the mean and median. Which measure of center best represents the data?

Answers

Answers:

Mean = 77Median = 90The median is the better measure of center

=============================================

Explanation:

Part (1) Finding the mean

Add up the values to get

80 + 90 + 10 + 75 + 90 + 95 + 99 = 539

Then divide by 7 because there are 7 values in this list

539/7 = 77

The mean is 77

--------------------------

Part (2) Finding the median

First we'll need to sort the values from smallest to largest

{80, 90, 10, 75, 90, 95, 99}

will sort to

{10, 75, 80, 90, 90, 95, 99}

The middle most value is 90 since we have three items below it {10,75,80} and three items above it {90, 95, 99}.

The median is 90

--------------------------

Part (3) Which is the better measure of center?

Nearly all of the values are clustered from 75 to 99. The value 10 is an outlier since it's far from the main cluster. There are more technical processes used to find out if 10 is actually an outlier or not, but we won't deal with that right now.

The much smaller outlier pulls on the mean to make it smaller than what it should be. The mean 77 is too small to represent what the center should be. The median is not affected by outliers, which is why it's used in applications such as home prices.

The median 90 is the better measure of center.

what conjecture can you make about the sum of firs 52 positive even numbers​

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete. However, the available details is enough to work out a solution.

Considering the first even number: 2

In this case, n = 1

The sum of the first even term is 2.

Represent the sum as a product:

[tex]2 = 1 * 2[/tex]

Considering the first two even numbers: 2 and 4

In this case, n = 2

The sum of the first two even terms is 6

Represent the sum as a product:

[tex]6 = 2 * 3[/tex]

Considering the first three even numbers: 2, 4 and 6

In this case, n = 3

The sum of the first two even terms is 12

Represent the sum as a product:

[tex]12 = 3 * 4[/tex]

Notice the pattern from n = 1 to 3

[tex]2 = 1 * 2[/tex] --- n = 1

[tex]6 = 2 * 3[/tex] --- n = 2

[tex]12 = 3 * 4[/tex] --- n = 3

------------------------------------

It follows that, the sum when represented as a product is: [tex]n * (n + 1)[/tex]

So, the sum of the first 52 even terms would be:

[tex]52 * (52 + 1)[/tex]

Where n = 52

[tex]52 * (52 + 1) = 52 * 53[/tex]

[tex]52 * (52 + 1) = 2756[/tex]

Hence, the sum of the first 52 even terms is 52 * 53 or 2756

Answers

▹ Answer

1/18 of a gallon of juice in each cup.

▹ Step-by-Step Explanation

Since we have 4/9 of a gallon of juice for 8 cups, we will divide to find the amount of juice in each cup.

[tex]\frac{4}{9} / 8[/tex]

Since this operation is division, we have to change 8 to it's reciprocal which is 1/8:

[tex]\frac{4}{9}/ \frac{1}{8} = \frac{4}{72} = \frac{1}{18}[/tex]

Our final answer will be 1/18 of a gallon of juice in each cup.
